I've been looking at the design of the wireless system, posted this over at forums.ouya.tv (http://forums.ouya.tv/discussion/1349/very-poor-wifi-stability) and thought it might spark something here.

There are many devices successfully using the Broadcom BCM 4330, which the AzureWave AW-NH660 inside the OUYA is based on.
So the chip is OK, we just have to alter the antenna configuration to hopefully improve the signal.

http://i.imgur.com/5bjwZj2.jpg

The white thing with the eights at U11 is a 2.4GHz chip antenna, though I still can't find the exact model.

The 3 pads at JC1... after poking around the internet some more I'm now fairly sure they are for a mini RF connector.

http://i.imgur.com/Z6No0n5.jpg

It appears the OUYA team went with a chip antenna instead of one plugged into a U.FL connector and the board was set up for either option.

Now we just need a brave soul to solder on a U.FL connector (https://www.sparkfun.com/categories/78) or an antenna and test it out. (probably would have to desolder the chip antenna as well, not sure though)

I also did some tests with the case on and off:

Got this apk from the Amazon app store that will graph your wifi dBm http://www.ampedwireless.com/wifianalytics/

Tested with the case on and off ~50ft from my access point through 3 walls. I don't usually get great reception in that room with other devices so I was actually surprised the OUYA didn't have problems.

Case on, then off.

You can see that the dBm only raises by a few points. I was able to decrease the dBm by about the same amount by putting my hand over the WiFi area of the board, so I'd say the case is not causing much interference.

I work in Quality Control for a growing industrial equipment company, I'm a hardware hacker and have an Ouya console on the way. :D

I also have a couple of UFL to SMA bulkhead and UFL to PCB antenna cable assemblies that I originally purchased to mod an old netbook, but could easily re-purpose to hack my Ouya console when it arrives.

I just have to obtain the connector and check out my Ouya to see how the traces go for that chip antenna.
With the SMA bulkhead connector assembly one can use a wide array of industry standard and home-brew antenna solutions from inexpensive omnidirectional antennas to directional antennas for greater range.

Looks like cooling and WiFi mods are in the offing for starters!
Good stuff!

Well I connected a plain wire in parallel to the original antenna as first test.
It did already help quite a bit!

There is no need to remove the original antenna, just turn this resistor, it needs to be soldered to the free pad:
http://abload.de/thumb/pcbjus8d.jpg (http://abload.de/image.php?img=pcbjus8d.jpg)
(yes it is quite small)

And test the temperature of the Wireless IC before and after soldering. In HF tech if you are unlucky a small mistake can cause high power loss heating up the chip and damaging it!

also this may be slightly off topic but i think there is also some problem on the software end as well, as I notice that whenever I use a wired controller (a pc dualshock knock-off) and turn off bluetooth, my wireless connection is considerably faster and more reliable... I have the exact same wi-fi chipset in my laptop, and [physically] sitting beside the ouya it blows away the performance of OUYA's wi-fi, until i turn off Bluetooth on the OUYA and then performance is exactly the same.

Great work on both fronts. Did you attach the wire before or after the original antenna? I've read that for 2.4GHz the antenna should be around 30mm and that copper ground wire works well. Excited to do some testing later.

I did a bit of testing. Initially I wanted to solder a 30mm wire to the chip antenna, but I realized this copper plated clip from Radioshack (http://www.radioshack.com/product/index.jsp?productId=2062233) I had was about 30mm and would require no soldering.

I clipped it on before the chip antenna and the signal improved measurably!

http://i.imgur.com/pj6KgJH.jpg

This was done with the metal case on and the top off in approximately the same location/conditions as my last test.

You can see that the dBm hovers just below -70 like the other test, but then when the clip is attached it goes up and hovers around -64.

The poor wireless signal is caused by the metal case of the ouya if you get a plastic case it will improve the wifi signal without adding any other artifact

Did you not see the pictures?

It doesn't matter if the case is on or off, it doesn't change the signal much with it in the case vs out of the case, its the crappy wifi antenna that they use that's the issue, did you even see the picture of the signal with the clip on the antenna on how much it improved the signal?

I know but some people got it to work that way i see it improves with the clip but you how it is people don't want to do this if their having wifi troubles

Actually it's been proven by the modders across multiple forums that taking it out of the metal case does NOT increase the wireless signal in any significant manner. This was something that people thought BEFORE all the modding and testing started. Placing the OUYA in the same place with or without the case is relatively the same weak signal.

The problem is more software than anything, but of course a stronger antenna will always work.

Thanks for this OP, really good info!

So, I got a U.FL connector in from Sparkfun today, and figured that I would have a go at putting it on the board. I made a few mistakes, but eventually got it to work!

Here you can see my wifi before the mod. It is hovering at around -60dB.
https://www.dropbox.com/sc/r8lflnbwzshg9ka/octG19O3Lz

Here is the connector on my finger to give you some idea of the scale that we are talking about here!
https://www.dropbox.com/sc/wh27lr3g8wr51si/rbNpn5lR3x

Here is the connector just sitting on the board, waiting to be soldered.
https://www.dropbox.com/sc/i4l2wk5mm5uyuvc/lyiLaAGAUM

The first thing that I did was remove the small resistor that goes to the SMD chip antenna. It was a little tricky, but I got it off without too much trouble. While I had it off I took the opportunity to measure its resistance, and am I glad that I did! Turns out that it is an SMD jumper, aka 0 Ohm resistor. This turned out to be a very good thing as I later ended up with it stuck in a ball of solder.

I managed to solder the connector on, but I misjudged how much heat the retaining/ground pads needed to reflow the solder. They are sitting on what must be a huge, and heavy duty, ground plane that took even my 50W soldering iron a few seconds to heat up enough to melt the solder. Of course, I didn't realize this when I first soldered down the connector, so I ended up pulling up the signal pad.

https://www.dropbox.com/sc/bnh3u1mbzqg6cth/Iat95ydM_P

So I ended up pegging the connector down to the ground pads (it ended up slightly crooked, but sturdy) and then soldering a tiny wire from some desoldering braid from the first pad of when the SMD should have been to the signal pin of the antenna connector. I checked everything with my multimeter, and it all checked out.

https://www.dropbox.com/sc/cfn2107gy22q0d5/7A5FshRq-c

I fed the antenna wire up through one of the rear screw holes for the time being and used some electrical tape to hold it in place on the Ouya. Eventually I hope to drill a mounting hole in the Ouya case, but this worked for testing.

And these are the results!

https://www.dropbox.com/sc/p91mtcyailej5mb/CNH2HFfmw1

Around 5dB gain, or about 3x better reception! Not too shabby! I also tested out my connection with the Speedtest.net Android app, and where before I was lucky to get 3Mbit down, I am now consistently getting 10+. Oh, and I haven't had to wait for a Youtube video to buffer since the mod. I'll let you all know if the performance remains consistent.

I don't understand why they went with that crappy chip antenna, all they had to do was put a connector on the board and ran a wire around the case (probably would have been cheaper, or right around the same price as what they used), and would have resulted in a much Better signal.

Fantastic work Fredjikrang! I laughed seeing the final solder job, about the type of blob I would expect myself to come up with. Glad you didn't ruin anything.

Surprised the antenna didn't increase the signal more than it did, but still a worthy improvement. Interesting to see that the two weakest wifi signals were bumped up enough to not cut out.

How far away is your router and do you plan on trying any other antennas out?

madmax2069: I wouldn't say the chip antenna is crappy quite yet, though I too am quite curious about their decision to use it over the connector. Two theories: 1. Connector and internal wire had no significant signal improvement over the chip antenna. 2. The connector was deemed too fragile to put in a system that encourages people to open it up. I believe most U.FL connectors are only rated for a few insertions before the coupling is compromised.

07-16-2013, 06:10 AM
Yeah, not my finest soldering work. If I did it again I know that it would turn out much better, now that I have a better idea of what is going on. Oh well.

It has been working really well so far. My actual data throughput, as measured using the Android Speedtest.net app is much, much better than it has ever been. I usually would be under 1Mbit throughput unless I turned my Ouya on the side (pointing the antenna at the router.) Even then I never got much above 3Mbit. Now I am consistently over 10Mbit, which is saying something since that is my average internet speed! I also haven't noticed any lag on my controller since then, but I haven't really pushed it yet.

I am a little tempted to try a 5dB antenna on it, but I really don't see much of a need at this point. I haven't had any problems with my connection since doing the upgrade.

My router is a good 50ft away, through four or five walls. It is an Amped Wireless R10000 though.

Question; has this helped at all with controller range and responsiveness? I haven't noticed too big of issues (though I haven't done a speed test) with my wireless with my wireless router a floor up and a room and a half over. My controllers however are only barely usable at 2.5 meters from the Ouya, and display lots of variable input issues.

07-25-2013, 07:50 PM
I think it should help, but what we really need to do is figure out how to get the bluetooth antenna on the controller working better since we know that the PS3 and Wii controllers have much better performance.

The controller appears to have an embedded meander antenna.

The chip is a BCM20730

I am curious about the two test points(?) and what their functions are.

Looking closely at the picture, the lower one is a fiducial to help the pick and place machine locate the parts on the board, but looks to double as a testpoint also, looks like to the configuration memory on the lower part of the board, my guess is it is an I2C or SPI memory device to setup the BCM chip for operation. You would have to pull the controller apart, but it looks like the antenna is hooked to the ground plane.

I'm impressed with how just soldering a wire on there improves the performance!
I'm guessing that cut to the right length it would do even a little better, but I'm not sure if it is a simple matter of cutting it at a 1/4 wavelength or not.

I just ordered a pair of U.FL connectors on Amazon:
http://www.amazon.com/gp/product/B00CXOC5Z4/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1

As I mentioned before I already have the antenna and cable assemblies, so once the connectors arrive it's just a matter of drilling a hole in the case and installing the hardware.
I'll post photos when I do my mod.

Based on what I've seen of the black 16gb model the connector is already on the PCB so when my black Ouya arrives I'll simply be drilling and installing the external antenna. THAT Ouya model is super easy to mod.

Didn't realize you were nearby, I might have to drop mine off since you like messing with these things :p

It really is a simple add on. Though I guess I wouldn't recommend it for someone who doesn't use drills since you might need a brad point bit to get a nice clean hole depending on the connector. I guess soldering shouldn't be left to those who don't it often but it's not that hard to do.

The antenna was posted but the shield wasn't. Wonder how much of an effect the shielding has on performance, we clearly know what the antenna does.

Michael Thompson
02-27-2014, 11:10 PM
The shield is intended to keep unwanted signals out, probably interference from the bluetooth system and/or other components on the circuit board.
That's one of the ICs I placed additional copper heat sinks on in my original grey Ouya.

PCB modification finished!

Here is the Ouya PCB with the fan removed and held in a couple of special clamps to stabilize the board while I'm working on it:

Here is the U.FL connector for the WiFi soldered to the PCB.
The 0-ohm SMD resistor that originally connected to the internal WiFi antenna has been removed and the connection from the Wifi components to the external antenna components bridged with a wire.
I did it that way because the original resistor (essentially a jumper) went flying off somewhere when I went to remove it (this stuff is super tiny folks!) and I didn't feel like waiting for a replacement to come down from our parts distribution.
The work is a tad rough looking but solid. I'd rather have a good ugly connection than risk messing something up just to make it appear prettier any day.

The WiFi cable is attached to the connector to complete the connection to the external WiFi antenna.

There is a cutout in the PCB that will allow the antenna cable to bend over the top so that the lid will fit with no problems.
Here is the PCB installed into the case and the antenna cable fully routed prior to the lid being reinstalled.

A dead WiFi router can be cannibalized for parts also.
I'm sure people have at least one of those lying around.
Some with two antenna's.

I don't have any hard numbers but I see a ton of wireless routers in my neighborhood now, and can connect to a nearby open Xfinity hotspot when I couldn't before.

My Ouya system sits beneath my Router so my own wireless connection remains awesome.

I would guess that with multiple controllers I could maximize BT performance and WiFi will still kick butt due to the higher gain external antenna and the fact that the systems won't interfere with each other now.

I'd bet that the Ouya PCB itself could be installed inside an older router enclosure with external antenna(s) with room to spare for a hard drive and USB hub!

It might fit in my old d-link. metal with antenna.
The cicsco one looks way cooler. no antenna but plastic.

Nope, if it aint broke....well maybe after I get an OUYA 2.

Any reason you can't leave the chip antenna hooked up and just bridge the connection from before the resistor to a new antenna?

Or would they interfere...

There isn't any advantage to it as the chip antenna is still inside the metal box.
The impedance would be wacky too, which could actually harm the WiFi chip.

This takes the antenna away from the bluetooth system and places out of the box.
I'm pretty sure it is one of the reasons that the 16GB models have a connector installed on the board and an antenna placed against the inside of the plastic box.

I'm new to this forum, so first of all:

Hi everyone :)

I was searching for a workaround for the controller lag issues. I'm always experiencing this while playing with multiple controllers connected. I was wondering if this workaround would also increase the Bluetooth strength and thereby fix the controller issue. I have never done any modding, so I really don't know. Sorry if this is a dumb question :)
Thanks.

Thanks do you have to bypass or disable the antenna it has already? I was wanting to go just the route of soldering the single wire for what it's worth

@Andy: If it's an option for you, you can send in your controllers to OUYA and have them update the firmware (this should be a permanent and best fix for lag.). You can also do a few things, Set your Ouya to prioritize Bluetooth over Wifi, tip it on it's side with the top toward you, and make sure your controller has fresh batteries and sit a bit closer to ouya.

@reesh: Soldering a wire to the chip antenna mount point works for a mild gain as seen earlier in this thread. I asked if we could both leave in the chip antenna and add an external one and that posed iffy to our resident expert ;)
My take is that if you are comfortable with your solder skills adding a wire is easy enough and reversible...if you want to go big then put a real antenna and disconnect the chip. (also easily reversible if you are careful.)
My ouya is from the kickstarter, connected via wifi and I don't have any signal issues. So I'm leaving mine stock.

I ran some tests using the speedtest apk side loaded on my OUYA. I bought my OUYA in October and it had been updated to the latest firmware. I ran each test 10 times in the same location to get a proper average.

OUYA wired ethernet: 29-31mbps (avg 30)

OUYA stock wireless: 3-4bmps (avg 3.5)
OUYA w/ "prioritze wifi over bluetooth" selected in options: 3-4mbps (avg 3.5)
OUYA w/ bluetooth turned off (ps3 controller wired in): 3-4mbps (avg 3.75)
OUYA w/ case removed: 6-8mbps (avg 6.5)
OUYA w/ single wire antenna mod and case still off: 8-12mbps (avg 10)
OUYA w/ single wire antenna mod coiled inside case: 4-6mbps (avg 4.75)
OUYA w/ single wire antenna mod running through hole in bottom of case and taped externally: 6-12mbps (avg 8.75)


The performance is still pretty weak but I am now able to stream 720p files seamlessly through XBMC- before they would stop to buffer every 10-15 seconds. I've watched three episodes of True Detective and they only buffer once when the video reached the HBO logo- bitrate of the videos spikes from around 5 to 20mbps at that point.

Also the wire antenna mod is pretty easy. I'd never soldered before, just went out and bought the cheapest iron from radio shack, some generic wire, and some rosin core solder. I have no idea if I was supposed to use a special type of wire or cut it to a certain length (I did about 10 inches). I also have no idea if this mod would somehow cause long term damage to the console, so don't take my results as a go ahead.

It is also interesting to note that speedtest always reported my upload speed accurately at 6mbps- even when the download was much slower. So like many people have speculated, maybe there is some sort of driver/software issue that is gimping download speeds. It may be intentional, possibly to reduce bluetooth interference. If so I really wish they'd put in an override option for people who are using the console exclusively for XBMC.

Nice to see raw data but it seems once the case comes off, things get better...as usual.
But some of the other mods here should possibly help with that factor too.

With the single wire mod, did you rotate the resistor as described by user82 in Post #3 or did you just solder the wire to the terminal as shown in Post #18?

I was considering doing the antenna mod but in the end I didn't have enough faith in my soldering skills. So what I did was buy a mini travel router (TP-Link TL-WR702N) which I set up in client mode. It receives the wifi signal from my main router and I connect it to my Ouya via ethernet. I now get full download speeds and I can stream HD video (only tried 720P) without any problem.

The mini router is really small- about 2.5"x2.5" x0.5" and cost me $19.99 off Amazon.ca. It does not have an external antenna but it obviously gets better wifi reception than the Ouya. It is USB powered but it comes with a USB wall charger. I power mine from a USB service port on my TV. That way the router is powered off when the TV is off. I considered plugging it into the Ouya's USB port but I didn't want to rob too much power from the Ouya, and I thought it might heat up the Ouya which would result in the Ouya's fan running more often.

I hope this is not too late to add data to this thread. Just wanted to share my results.


https://dl.dropboxusercontent.com/u/98507800/ouya/Ouya-Antennae.jpg

I modded my Ouya with a 6dbi antenna. I upgraded from the stock wireless cable to the RG178 just to be extra safe. Parts retreived on ebay for about $12. Soldering, drilling and assembly time took only 10 minutes. It wasn't that bad really! I destroyed the 0Ohm resistor and then solder bridged the connector to the UFI port. Used a micro-drill bit on a dremmel to start the hole and slowly shave outward to make it large enough for the antenna to fit through.

These are the signal strength before the modification. thunderdome is my wifi router sitting on channel 9.

https://dl.dropboxusercontent.com/u/98507800/ouya/net01.png

Not much going on out there.

https://dl.dropboxusercontent.com/u/98507800/ouya/net02.png

And i'm sitting around 50dbi which I guess is average for the Ouya being about 12 feet away from my router. My Iphone gets around 55-60dbi when i have it on the desk.

After the 6dbi antenna mod!

https://dl.dropboxusercontent.com/u/98507800/ouya/net03.png

Oh hello! There's more access points out there.

https://dl.dropboxusercontent.com/u/98507800/ouya/net04.png

And i'm down in between -30dbi and -40dbi. Which is a rather large improvement! Not bad really!

Finally, since I have a Netgear WNDR3700v2 with DD-WRT loaded onto it. I can reverse check the dbi ratio from the Ouya into the Router.

https://dl.dropboxusercontent.com/u/98507800/ouya/DD-WRT-Network-cross-check-Ouya.jpg

DD-WRT is more critical towards the devices connecting. My Pi is right next to the router about a foot away, which is why its connection is awesome. But the Ouya for being 12 feet away shaving 10dbi off the top is something I will definatly take!

So conclusion on the wi-fi access point = Success! I can now feel comfortable taking my Ouya to larger venues where the internet connection at a hotel may be spotty and still be able to connect with ease.

Thanks guys!
