[Q] Wifi detection range and signal huge decrease - Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl

Hello. Recently, I opened the back cover of my note a couple of time to reattach the loose LCD ribbon in my tablet. During this time, Isomehow,noticed that the wifi was not working! Well, it was working, but I cant use my device unless im < 10 feet away from a router. However before, it was working perfectly fine, and on my other.devices, everything is fine. Is this a well known problem? Did I damge the internet card in my tablet? Also, the signal is around -60 when im close b
ut when.I walk 10 feet away it is like -90.

I would imagine you have disturbed the Wifi antenna. I haven't seen inside the tablet, but it would more than likely have at least one antenna connected to the Wifi module.
It's usually a thin wire running on the outer frame.

My tablet can not see my wifi router when it suddenly shutdown.
I don't know why my tablet never see name of my wifi router if suddenly turnoff wifi router. I used WP2 and AES & TSKIP.
And if want my tablet P600 see my rounter wifi, i must go to wifi router setting to change AES or TSKIP and then my tablet can see it. But my galaxy s4 don't have this problem. Maybe kernel of galaxy note?

[Q] Solutions for OUYA's weak wifi?

Got mine yesterday. Biggest complaint is the wireless receiver is pretty weak. I had the OUYA upstairs where my phone, laptop, and ATV2 all got a strong wifi connection. However, the OUYA kept dropping the connection every few minutes. I had to move it downstairs, in the same room as the router.
Has anyone found any solutions for increasing the OUYA's wifi range?
noticed the same thing about weak wifi signal...wonder if it's a hardware design issue or a driver issue.
Yeah, I've noticed the same thing. I actually have to AP's - a netgear router in my outside office where my cable comes in and then a WRT-54g setup as a repeater to serve my house. My TV, Living room PC, Wii, tablet, and phones all get a great signal off the WRT and the Ouya even reports it as a good signal - but refuses to connect sometimes and drops the connection all the time. Oddly enough the Ouya has an easier time connecting to my netgear router even though it shows a "fair" signal at best. So I'm thinking maybe the Ouya is just kind of picky about what it likes to connect to. But I also usually see at least 6 AP's in my living room and the Ouya only picks up my 2 - so it does seem to have weak reception.
Thinking I'm going to reconfigure my network this weekend. I've been working from my official office more lately and don't use my outside office much at all anymore so I'm probably going to reverse things and put the router in the living room so the devices in there can be hardwired and the office will run off of WiFi now instead. Been thinking about doing it for awhile the Ouya is just the final straw.
One thing I've considered doing is using the Ouya out of it's case to see if that improves it's reception any, it's really easy to remove from the case (4 hex screws on top then the board just pulls out with a gentle tug - but be careful not to get the grounding clip caught on the lip the lid fits into) and with the case being aluminum it could potentially be attenuating the signal. Since they released design files for the case if running it out of the case helps it wouldn't be that hard to get a plastic case made for it...but I'd hate to have to go that route just on principal.
For whatever reason I did have better luck getting the Wifi to connect when I went into Mange->Settings->Advanced->Wifi and used the unskinned android settings menu to setup my wifi. using the Ouya's menus I was never able to get it to connect to my WRT repeater. But using the stock settings I was. Not sure why that should matter but there it is.
I think it is a driver issue. Install speed test and seer what results you get. I get higher upload speeds than download speeds and using Ethernet it ifs no where near where it should be. Not enough off an improvement to make connecting it worthwhile.

Someone else posted somewhere, that they turned off ethernet once they had wifi connected, then hard reset the Ouya, and it sped up the wifi connection. I can confirm this for myself as I tested a file transfer through ES File Explorer and it jumped from 3 kbps to 45 kbps. Still a lot slower than my other wifi devices in the same room, but at least it became usable.

Hard reset as in simply pressing the power button, or by disconnecting power?

Try just rebooting (hold power for a second and select power off). It's never a good idea to just pull the plug.

Yep this.
Didn't really have enough difference for me. Range and speed are still flaky if I'm more than 20 feet from the router.
I'm still waiting for OUYA to recognize this as a problem, and hopefully put a stronger wifi chip in for retail. OUYA support has told me that weak wifi on the OUYA is not a widespread issue, so seems like they just want to deny the problem.
They either need to:
Increase the power to the wifi chip
Use a better wifi chip
Use a wifi chip that can utilize a wire antenna for better range
Build in drivers for some external wifi adapters
Sucks that I'll have to get an wifi repeater, wifi bridge, or something else to get the OUYA working in a room where my laptop, ATV2, phone, and tablets all work fine.
Mine dropped out completely when I tried to login for the first time after updating, had to turn the Wi-Fi on/off a few times to get it to work... and it's sitting 20cm from the router!

Yes, mine is extremely flaky still as well. So far I'm pretty frustrated with the problems that are arising with Ouya, which is too bad, because I actually really really like it should far. I honestly wish I'd waited until retail now, because I would have had a better/more finished product for less money and hassle.

Is anyone still experiencing Wifi problems? I just got mine hooked up today and had a ton of problems until I updated the software and reset, have not had a single connection issue since.

No. Mine worked out of box. I have an Ouya1-b
I have experienced zero issues, but I have an enterprise class dedicated wireless access point (a Ubiquiti Networks Unifi AP if you're curious), so I get full bars everywhere in my apartment and coverage like 20 feet out into the parking lot outside my apartment.
Since I also have a gigbit network everywhere in my apartment, I have generally just been disabling the WiFi.
One sort of issue I have noticed with the networking on the Ouya is that Android was built to allow for multiple network interfaces, which is only natural given that pretty much every smartphone has WiFi and also some sort of "mobile" data as well. Turning off the WiFi doesn't seem to always "stick" for whatever reason, so I may end up just "forgetting" my normal WiFi network in the network settings to prevent the WiFi from being used.
I have been toying with the idea of taking the Ouya mobo out of the aluminum casing, as its trivial to do and many people have speculated that the case is causing BlueTooth and WiFi signal issues. I HAVE experienced some weak connectivity to the controllers, and wanted to isolate the issue to either the controller or the console.

I tried taking it out of its case, and it didn't have any noticeable impact on my WiFi.
what about Bluetooth? Thats the thing that would effect the controllers, which are the element which is having a reception problem...

I didn't know the case was aluminum. Seems kind of odd choice of material. The Ouya isn't handled much, so there's no tactile advantage to using aluminum. The Ouya has a cooling fan, so heat dispersion isn't a huge issue if they chose plastic instead of aluminum.
What's the wired network speeds like? Can anyone test it?

Since switching to Ethernet (and turning off WiFi) things go much faster. Streams 1080p movies without an issue, and game downloads are pretty fast. Thumbnail loading on the OUYA menus still could be faster, but I think that's more of a firmware issue with the way those are handled, rather than internet speed.
i think the worst part is that they refuse to fix anything or acknowledge the issue. This topic is covered on several other websites, even their own support website. Ouya seems to keep saying this isn't a global issues. so does that mean in the future if we are having other issues they have to be global in order to be fixed or updated?
This seems crazy. i have 4 devices right next to the ouya and my ouya download speeds are less than 107 kbs, but all my other devices are between 5-10 mbs.
i tried to erase everything, reboot it, and now i cant even connect and maintain a wifi connection and get past the ouya upgrade page on set up. It says im connected, then timesout and says i have no wifi.
and to make matters worse im not really close to a ethernet connection, my router is upstairs and my tv is downstairs.
This just seems crazy that a company could releases a product in such an alpha stage and not take the people who helped make them successful seriously.
I've seen speeds of nearly 2-3mbps on my Ouya, which is consistent with my Nexus 10, laptop, and others (no way to install steam to see if Ic an get Steam's stupid 7mbps...)

Weak Wifi Strength?

I really only use this phone as a tiny tablet, no service on it, so its airplane mode. wifi only, its a great device. But im having weak wifi connection, the wireless router is in a bedroom, and in my office, which is just across the living room from the bedroom with the router in it, its one bar, - 88db, etc ,sometimes no signal, i'll be trying to check email on it, an ill have to stick the phone up in the air or move it around before it picks it up again,etc. i've tested same spot with ipod touch, an its has almost full bars -40ish db, no problems.. so im thinking its the phone, has anyone else noticed it?

Yes, my phone likes that. Hope 4.2 or 4.3 will fix it.

[Q] poor wifi signal.

I am facing a weak wifi problem since I bought it, it was refurbished and it had android 2.3 and htc sense 3.0. i updated it with 4.2.2 r11 .
The problem is that when i sit with the router then it only get full signal, if i move even 2,3 steps signal drops and after 5 meters there is no signals.. laptop and other mobile works fine with the same router so no problem with the router.. so is it the battery cover problem or IC is weak??
i have tried one thing and it even works but it is not a proper solution.. what I did is I connected a small wire with the terminal of wifi which is under batter cover and it is so thin that it easily came out of battery cover.. it increased wifi signal power.. so any one knows what could be the problem be? THANKS IN ADVANCE..
Could be a multitude of things.
Loose battery cover

[Q&A][i9195] Low wifi connection.

So in one room in second floor there is 1 bar wifi. My i9195 disconnects after sometimes and have to wait until it connects while others have no problems. With other phones (s2, lg 70.....) it don't disconnect and everything perfect. Even they can brows in third floor and for me no chance to connect wifi and browse etc. Is this problem with phone or this phone has bad anttena? If someone has same problem with i9190 please respond is everything Ok.

I recently got S4 Mini i9195, and noticed same problem, wifi was absolutely poor. I started searching on the internet, found where the antenna is, and decided to take my device apart. And you wouldn´t believe what I found.... all other antenna contacts on motherboard are bent, they are in a ˂ shape - so they can flex and touch antennas integrated in middle frame chassis. Wifi antenna contact was absolutely straight, parallel with the MB, so there was no way it can touch antenna on the chassis. I used needle and carefully bent the contact in correct shape, assembled phone and voila - wifi signal is full.
It seems it was a production error, I´m surprised nobody noticed it before.

The bigger the network of chromecasts, the harder to connect?

Hi guys,
We've just setup our chromecast network. Now with 1 or even 2 chromecasts in the network, everything runs smooth. But if we switch to a bigger network with 3 or more chromecasts, the connection is really hard or won't even happen at all. Anyone experienced this as well? The Wifi is new and quite strong (with additional routers on the first floor, so the wifi shouldn't be the problem).
Thanks for the reply
This is a limitation of WIFI. The more devices you have on a wifi, less bandwidth you will have available. WIFI protocol is using air time allocation protocol because it can talk only with one device at the same time. More devices you have active, more times it will switch between them to deliver all the packages requested. If you have wifi booster or extenders, I would recommend you to grab them all, smack them with a hammer, put them in water, take them out, dry them in the microwave oven, burn them with a torch and trow them in the garbage because that is what they are. Extenders ads latency and packet loss and also is reducing your bandwidth in half before you even have a device on. Do it yourself or contact a professional to install UNIFI from UBNT or similar products. Huge fan of their gear. If you have it properly installed and set-up(not just plugged in) you wont have any problems with any devices not just Chromecast.
BTW, strong WIFI doesnt mean anything. Your wifi is as strong as the weakest device. You can have a wifi that transmits 10 miles, if your other device transmits back only 30ft, it will be 30ft max wifi range even if at 300ft it shows full bars. The best thing to do is add a bunch of AP with the transmit power on the lowest. Keep in mind that wifi 2.4 has only 3 true channels that wont overlap: 1. 6 and 11. If you set them all the same channels they will hurt them self with their own noise floor. If you properly set them up with a spectrum analyzer, to be right at the limit, you could make them all same channel and do cool things like zero-handoff. Performance WIFI requires knowledge and proper set-up not just plug and go.
