[Q] Jelly Bean Wifi Problems TF300 - Transformer TF300T Q&A, Help & Troubleshooting

Hey XDA, I've lurked around here for awhile, and you guys have usually solved my problems without me having to post a thread.
This is my first thread post asking for help, so hopefully you guys can help me.
I have a TF300, running JB, unrooted. I am at college, on a WPA2 Enterprise network, using PEAP and MSCHAPV2.
Problem is, the Wifi is incredibly intermittent. Sometimes it will work just wonderfully, and sometimes it will take multiple resets just to connect to the network. Sometimes, the tablet will say that it is connected, and load one page or two, then begin to timeout, still saying it is connected.
I understand that on a WiFi network, signal loss occurs. But, this is happening in the same spot, and sometimes it is so bad that I just give up and stop using my tablet.
Hopefully you guys can pull something through. I love this tab and don't want to sell it.

[Q] Anyone else Having wifi connection issues with the xoom?

Hey I was wondering if anyone else was having wifi connection issues with the xoom? Every time I use my xoom I have to keep retrying to load the market, webpages and everything else that uses data. Usually have to reload the market around 3-5 times to get it to work. I have tried 2 different routers and stilll the same thing. Please let me know if anyone else is having this issue and if there is a way to fix it. Thanks
P.s. When Im on 3G everything is fine
I get it but only with Market, I assumed it was a market issue.
On. 3G, for me, everything is dog slow, but I never get the Retry box.

Mine works perfect with my AT&T U-Verse gateway and tethered to my AT&T captivate. No problems here at all with wifi. Do you have problems with other wifi routers? Go to Starbucks or a friends and see if the same issue occurs. If not, there is something with your router that Xoom does not like.
I'm having WiFi issues as well. I don't have any issues with any other laptops in my house ... but my Xoom ... get very poor signal on WiFi and sometimes doesn't get any connection at all. This is serious buzz kill.
Mine is also choking on wifi. Switch to 3g and no problems. Annoying.

Hardly surpisring when the antenna is surrounded by glass and plastic
Wifi is suspect on the Xoom. I cannot get a connection to my secure wireless at work but I can connect to the less secure guest wireless network. I also could not initially tether with my phone (TMobile Vibrant) but after I downloaded Mobile AP I was able to tether just fine and have not had any issues since then.
No complaints here to report. I'm pulling in on average a speed of 17mbps download on most days from my home wifi network. Quite the speedy little guy my Xoom is.
WiFi hasnt been a problem for me either.
So far, I've used it on 4 different wireless networks (G and N/G), using various security options and I connect to each without fail. Hell, Ive even seen the Xoom connect to WiFi when driving down the street towards places that I have it configured to see.
I did have some trouble at one point due to my DNS and DHCP servers being offline. I didnt suspect any issues with them, so I spent more time than I should have troubleshooting the Xoom.

Always Connecting...
Greetings All,
I have been having issues as well after the update. The wireless always disconnects and connects and doesn't stay connected. No problems with my Droid X or laptop or other device.
Problem is that now I'm getting very close to going over my data plan.
Is there a fix in the works, since it worked perfectly with 3.0
Annoyed...

UPDATE: Uninstalled the leaked Flash 10.2 and that has fixed the problem, somewhat. Still disconnects, but less.

Wireless issue fixed....
Greetings again,
Even after uninstalling flash, the problem persisted somewhat. I was getting very frustrated and so I reset the xoom to factory settings. A few notes on that. All applications were reinstalled, through the market which is good and bad.
So far, after 2 days of heavy wireless use, not a single drop in wifi connectivity.
Hope this helps...

So far my wireless is great. I use WP2 Secure at home, a WEP at my parents, and a MAC based approval network at work. All are steady with full bars and no issues.

Its the encrypton protocol, WPA2 with AES will cause problems.
TKIP works.
I also have random issues. Some days its just fine, but other days wifi works and then stops working, usually a reboot fixes it.
Must be some wifi issue.
I have a fully factory stock xoom and have had NO wy fy problems at all! internet conection firm and stable. I intend not to root my zoom untill all the important updates are done and stable. I also am waiting for my 4G card install. I have WPA2 with AES and the xoom conected to it with NO problem
I haven't had any problems with mine whatsoever. I think it could be your router. My Xoom stays connected with my router and I haven't had a single problem so far with connected wifi.
My PS3 needs a router reset every single time I want to play Black Ops though.
ihad this issue. I think it may be hioneycomb and not xoom related because I experienced it on the acer iconia. The good news is that I resolved my connection issue with wifi. On the surface it looks like a dhcp handshake issue so, if you assign your xoom a static ip from your router, the issue goes away and all is good.

[Q] Internet Loading Delay

I was told on another forum that this issue I've been having, is being talked about here on xda, and is some new bug that isn't figured out yet.
If I could be pointed to a thread that is talking about this, thank you.
My problem...
I've been dealing with data issues for 5 days, and I'm going crazy!
Long story short, had zero data for 3 days, spoke with tech support for over an hour, and ended up hard resetting, which ended up bringing back data.
Now to my current problem. I can't seem to find anyone else with this issue. From the stock browser, or Dolphin HD, I try to load a website (any website - even a small page like google), and I'll have a delay for about 20-30 seconds before it wants to do anything. Once that delay passes, then I have my normal 4g speed loads. However it only loads about 90%, then stops.
I've had a couple page loads that acted normally, but 99% have had this horrible delay, with a good handful not loading at all.
Please help me figure this problem out.
Please, someone. I really need help with this.
See this thread.
tl;dr: Verizon appears to have problems with IPv6 lately, and their DNS servers are returning v6 addresses for some sites. Your problem is most likely that you're failing to get to the site via IPv6 (which is preferred) and it waits to timeout (30 sec., usually) before switching to IPv4. If you're rooted, you can force a different DNS server (Post 47). Otherwise, 3G won't give you trouble.
Thank you so much!!!
Not rooted, so I guess I'll just switch it to 3g until things get better with Verizon.
Do you happen to know if this is something that they are working on and will be fixed soon, or might it be like this for a while?
Switching it to 3g worked perfectly. Thanks again.
I've always had a super strong 4g connection where I live and work, that I've never really had the need to switch to 3g.
Going to miss my 4g until they get it working again though
Unfortunately, nobody knows when it'll be back to normal. If you call and talk to a tech, they'll just tell you that they're still rolling it out and will fix problems as they can.
Personally, I think that Verizon's DNS servers just haven't propagated the removal of the AAAA (IPv6) records. Once that happens, and the phones update, your connection should return to normal.

Y'know, switching between CDMA and LTE should result in a new DHCP request, which also might result in you getting a different DNS server. If you've got nothing better to do, you could try switching back to LTE every hour or so and see if you get a better/more current DNS server.
Worth a shot. Might as well give it a try. I'll be sitting at my desk at work for the next 6 hours, so...

[Q] Wifi at home issue

Hi Everyone.
I am not a developer nor really tech savy, but I do know how to adjust a few things. Anyways, I just got my Infuse 4G, loving it so far except at my home. I have really fast internet connection and my router is new and is Cisco. My laptop, desktop and tablet all work really well. My infuse though will connect and tells me that it has a really strong wifi connection, but I can't open anything for **** such as a browser or market app. It works fine at work and at any att wifi hot spots.
Can anyone advice me on this? Sometimes though, it works fine but about 85 % of the time at home, I can't open any internet connection although it says that I am connected to wifi.
I am about 5 days close to returning this if this problem can't be resolved.
Any help will be really and greatly appreciated.
Thank you.

Probably your router. If it's Linksys-branded Cisco of the "saucer" form factor - find something better. Linksys-branded Cisco hardware sucks these days.
I suggest finding a router that is supported by DD-WRT - I have always been disappointed when running routers with closed-source factory firmware.

I would think that if it works well at work and att hot spots that this would point to ot being an issue with the home router.
Have you tried resetting the router?

resetting meaning turning it off and wait for a few minutes and turning it back on?
No, but if that was the case, my other devices shouldn't work neither no?

Some routers are buggy and don't play well with some devices.
90% of the time it's the router's fault.

Wifi Issue: sell GT7 or wait for ICS

Dear seasoned Xda members,
I love my GT7+ and have enjoyed the versatility of the Android Os (my first device). As I carry the device around and (attempt to) use it at work the size is perfect. However, I have terrible issues with the WIFI. At home there is no issue - but I work in a hospital, and the device is only good for me if it can get WIFI.
Well... in the hospital it will connect to both the "guest" wifi and the "secure" wifi (for which my device has been setup), but in both cases the connection just "dies" after about 2 minutes. The only way to get on again it by re-booting the device.
I had hoped that all of the firmware updates would address the issue - and I have read that some routers are troublesome for the GT7+. Unfortunately I will have little control over what routers are being used.
The device is no use to me if I can't use it at work - and Im wondering if I should sell it or if ICS will resolve the Wifi issue.... I would appreciate any guidance even if its speculation.
[btw the device is entirely stock, not rooted, and using ADW instead of TW]
Cheers!
Here's samsung's ics update list.http://androidandme.com/2012/02/devices/official-samsung-android-4-0-update-list/. You'll probebly have to wait until Q2 or Q3 for ICS, unless someone ports CM9.

I guess it was my fault to get the WIFI only version thinking it would be easy to switch between networks. Seems like a bug that they should have wrinkled out before shipping a "Wifi-only" device.
In any case, if anyone is looking for another device to play with - shoot me an email (aliota [at] gmail.com)
I had the same issue prior. I bought this Tab twice and with both devices the same thing happened at work aswell. At home it was working perfect. At work any wireless connected but dropped in like 2 minutes. Very Frustrating. I was actually thinking of picking it up again assuming the issue had been fixed..

Have you tied to do a factory reset on the device and then reconfigure the wifi connections? I bounce between many wireless networks during my day and the connection is stable.
I did have a few reboots until I set the wifi to turn off with the screen and never to turn off when charging, now the device is rock solid.
I believe that once ICS is dropped there will be some custom firmwares (ROMS) available for the device. Every new device I see posts like this where there is one feature or another that is flaky, once the developers start working their wonders on it the device becomes wonderful. The biggest hold up right now for development is the WiFi driver. Based on history of other devices, eventually that will be overcome as well.

Interesting... I've tried this in the past without any luck, but will try again. I really want to keep the device because it is quite powerful and the 7" size makes it much more portable than a 10"+ tablet.
Thanks for the feedback.
I have noticed some wifi issues with mine also but they dont seem to big of a deal for what I use mine for. I would really recommend keeping it as it is duel-core, lightweight, can even fit in some pockets.
But rather you keep it or not I suppose depends what you use your tablet for mostly I suppose.

Google or Zyxel? WFi issues on Android devices only

The Problem: WiFi disconnects every time i am barely downloading anything or just watching youtube, and re connects, and so on.
WiFi Modem: Zyxel P-2812HNU-F3
Ever since i bought Galaxy Nexus back in December 2011, I have had WiFi issues 24/7. I thought it was a hardware problem, but then i went to my friends house and tried his WiFi and it worked great. He had a linksys modem while I had Zyxel. Back then i honestly didnt think that the Zyxel modem could be the problem. Thats because i had Galaxy S 2 before Nexus and that phone worked great. But SGS2 was on 2.3. So i thought that Google ****ed up when they released ICS. I still do, for some of us. If you have the time, please look at this thread in Galaxy Nexus forum, where we discussed the problem:
http://forum.xda-developers.com/showthread.php?t=1386884
Long story short, i tried changing lot of things in router but nothing worked. When 4.1 was available for my Nexus, i downloaded it without even thinking that there might be a WiFi fix because i had given up on WiFi. I used 3g until 4.1 was out. Anyways, a few days after i had installed 4.1 i turned on WiFi and run a test in Speedtest app. Speed was great. But the thing i worried about was WiFi being disconnected. So i tried downloading a gameloft game and no diconnect. The whole game downloaded fine. But after a few hours later i noticed after downloading some movies it sometime disconnected and reconnected. I was mad at google again. But JB was much, MUCH better then ICS. Atleast i can use my WiFi now. Sometimes it works, other times it wont.
Yesterday i got my Transformer Infinity. This device is on 4.0.3. The first thing i did when setting up device, was downloading speedtest. I ran it, and it had the same problem that ICS on my Nexus had. I began to search again why this happens in ICS. I downloaded WiFiFix manager but that didnt help at all. Many other zips and apps didnt help either. So... Today, or tonight i opened up router page and started changing wpa2 to wps, like i did months ago for Nexus. But nothing helped. Then i wanted to try omething i havent done before, so i changed 802.11b/g/n to g only. Now WiFi works greta on my Infinity and Nexus. No disconnects at all! (lol i so hope that this is a permanently fix)
I dont know how that will effect my other devices, mostly PCs. So is this a Zyxel issue or Android? WiFi with n works normal with my PCs and other android devices. This must be because of 4.0+, right? I dont think its a hardware issue at all because my Infinity behaves same way.
Should i stay on 802.11g or is there something i can do to fix my devices to work with 802.11n?
Or is there a way i can enable 802.11g for Infinity and Nexus only, and use 802.11n for the rest?
