wifi not connecting/disconnecting after a second

I have searched the forums and found nothing to help. My Evo is rooted, and I have not recently flashed any Roms. Last Wednesday or Thursday this started happening, my evo just will not stay connected to wifi, any wifi. Once it connects it disconnects within a second. I have tried to reboot the wireless router and modem in my house to make sure. My girlfriends Evo connects fine full bars. Other times my evo cannot find my wireless router at all and just continues to scan. My wireless router is encrypted WPA2 and N.
For 2 weeks now I have been running Going Green Lightening 10-20 without any issue, the wifi was working perfectly. I tried to flash a different rom, same results. I read some other post that suggested flashing a new kernel, tried this as well and still not able to stay connected or see the wireless router. I've tried to connect to the wireless at work and recently stayed in a hotel and my still cannot pick up wireless. Anyone seen this happen before or have any suggestions?
Edit: I flashed freedom kernel, now I get a wifi signal but its not very strong. If I leave the room that has the router in it, my signal just drops. This has worked fine for over a year and all of a sudden it just kinda died. Any help would be appreciated. Also I am contacting HTC regarding this issue, I doubt sprint can help and I do not have the TEP any longer.

This can be closed I found the problem.

What was the problem?

my antenna is broken, the tape looking stuff, has a rip. So i have to replace it it should work.

i just had this issue, this is what you do:
Back up everything into Titanium Backup
Boot into recovery
wipe cache, Dalvik, and pretty much everything
reflash your rom,kernel and gapps (or if you would like to check out some other roms and kernels just click on the link in my sig)
once you've set up your phone download Titanium Backup from the market
in titanium backup restore all your apps ONLY!!! (don't get apps w/ data - only get apps, and do not get system data)
after this your wifi should be working just fine

Lol damn. Now is when I notice I have to many apps. Thanks for help. I'll give it a shot.

Replacing the antenna worked for me. For everyone else I did see where clearing the cache, dalvick fixed it. Also try to flash a new kernel it did fix my issue originally, but just not distance.

[Q] Weak Wifi Signal

Hi. I am having very weak wifi signal and the signal keeps droping on my one x while my old sensation at the same place has better wifi reception. Any one facing this problem or any one has any fix? I have the insertcoin 3.3.0 installed. Even with the stock firmware i faced the same issue. Thanks in advance.

Hi,
I'm facing exactly the same problem...
only when standing in a range of a few meters from the router, I have a good connection.
My desire has a much much better connection.
do you think we have to send it back?
gr,
F

I had to buy a plug in wifi extender, put it into an area in the house quite far from my wireless modem router, One X now has much better wifi reception.
My Samsung Galaxy Nexus never had this problem, or Nexus S, or Nexus.... seems the wifi reception of the One X handset is weak.
By the way my modem router is Netgear 1000SP and my wifi extender is the Netgear one. Very easy to set up. £69 (in the UK).

but that will only solve the problem at home and not at work or other places

I have the same problem. My HTC Desire has much better WiFi reception than my One X. I tested it with the WiFi Analyzer app and the difference in signal strength is on average 10 DBm, which is quite large difference. For me it makes WiFi unusable on the top floor of my house, where the Desire never had problems. With the One X I have set WiFi to Best WiFi in Settings, but it didn't help much.
What I also noticed are very large variations in signal strength. In a room next to the room where my WiFi router is, I should have strong signal, sometimes I have 2 arcs signal strength in the WiFi icon, but sometimes those bars drop do only the dot in the icon, so a large difference.
edit: as far as I can remember, before the update I didn't notice the WiFi problem, but that might be due to the fact I just got my phone. I haven't unlocked my bootloader so I can't test it myself, so maybe somebody else is willing to test that? It's important to find out, because if WiFi really was better before the OTA update, it means it's just a firmware issue. If not... it can be hardware.

I think its a software issue as many of us are facing the exact same problem only when away from the router. My router is on the ground floor and my room is on the second floor. Its just that floor where I am facing the problem while my sensation has got a decent signal. I feel its a software issue and the next update should hopefully solve it.
I am also having weak signal on ground floor rooms where the router is just 7-8 feet away from me.

I just sent my One X back because the wifi signal was so poor
about 15 feet from the router i had 1 bar signal any further non, what so ever. Pretty much made the phone a useless pile of ****e when it comes to using wifi.
Spoke to HTC regarding it but they told me to send the phone back, i will see what the next phone is like, most likely the same by the sounds of it if other people are having this issue

Please let us know if your next phone is (way) better, because if it is, maybe we need to send it back too. For now I keep having the hope that it's just software and will be fixed.

I just got my replacement. The Wifi is alot better. I have full bars in the same location that i had 1 bar on the old one
There is definately a big difference, my main problem was at home, but i had 1 bar at my desk at work aswell, i now have full bars.
I havent updated it with any firmware as of yet, but it said there was non available when i last got it to check.
If it helps at all its Build 1.26.206.2
Worth sending yours back, there seems to be a few people with this issue, but if it was a fault with the model i would expect alot more people complaining, not just the few of us
I think my replacement phone they have given me an o2 Rom one due to the fact it has crappy o2 software on it... not to happy about that but at least the wifi works

And did you update your first One X? (or do you know which version that one runned on?)
(because like I stated in one of my previous posts, I don't recall any problems on the first firmware, which was 1.26, but I used it only a few days with 1.26. Now I'm on 1.28.)

I updated yeah, i believe there was an update on Friday or so, unfortunately i didnt take note of what version it updated to
This phone is o2 branded by the looks of it, its not what my original phone was it was unbranded completly, i may take this one back aswell, tho not sure if its worth it as at least the wifi works. O2 wont release the update as early as the unbranded presumably.
Suppose i could just custom rom this and get rid of the o2 stuff

Would you be so kind to look up what radio version you are running now?
With my old Desire I would just flash a different radio myself, but that's not possible without S-Off.

Yep no bother it is:

Hope that helps

I have the same issue with the wifi signal. I tried to install the 1.28 european ruu and some custom roms, but did not work. Do you think that it is a hardware or a software issue?

I think its possibly firmware, like wph says in his posts, I'm sure before the phone had latest firmware there wasn't a problem.
Is it possible to flash the older Rom and firmware?

No that's the problem. Flashing an older RUU will not work, since the bootloader has changed and doesn't allow an older bootloader to be flashed. Unlocking the bootloader doesn't help since it doesn't give S-Off and therefore it's impossible to flash a different radio/baseband.

So will have to wait to the S-off to flash a new radio and hope that could solve the problem?

Like I stated above, if I recall correct, the problem wasn't there with the old radio. But I only used it a few days before the update came. If it's just the radio, maybe HTC will fix it with a new update, so it could be with the next OTA update. If the next update doesn't contain a new radio, then the wait will be longer. If the radio from 1.26 was really better, it would be nice to know that for sure. That means I don't have to send my phone back. And there S-Off would be handy, then I could test my premise. If the radio isn't the problem, but it's hardware, then waiting is pointless and we just have bad luck with our devices.

I mailed the seller yesterday concerning this problem, and they are going to change my device. I will send it today, hoping to get it back asap.

WiFi issues

I'm not sure what the deal is, but sometimes the phone stops working on my WiFi connection at home. It also seems to have trouble when switching from 4g to WiFi... The only solution I have found so far is to reboot the phone... Anyone else having these sorts of issues?
Sent from my Lumia 900 using Board Express

Do you see this issue when you are using the WiFi or when resuming from Screen Timeout?
If you are seeing this issue when resuming from Screen Timeout, then it is not a problem as the device will switch OFF WiFi when not in use and turns on automatically when you turn on the screen.
If it is the not the case, I think there might be a issue with your device.

You're not the only one. I've seen that issue as well. As a "test", I turned off my wi-fi for the better part of a week -- and just used by Data connection everywhere I went (home, work, etc.). Not ONCE during that time did my data connection stop functioning. Not even a single time. I've just turned my wi-fi back on to see what happens.
I'll report back.

I've got the same issue and so do others on WPcentral and the Nokia support forums. To me, it sounds like a software issue. That being said, my 30 days are running out, so I'm going to swap out my device sometime between now and Monday, so I should be able to let you know if that fixes it.
Losing my saved games and app settings will suck, but at least I'll have the peace of mind of knowing for sure if it's a device issue.

Last night I started noticing the same issue. I applied the fix Nokia released and since then I have seen some weird issues. Last night i was trying to download an app and it was just stuck at the four dots. I then also tried IE and it was slow and pages would not render. I then powered off/on and got the same thing.
This morning I was trying read something on the web and had the same effect. just for Sh!ts and giggles I turned off WiFi and tried to browse using LTE and it was super fast.
I had a green dot replacement and was hesitant to apply the patch but said what could be the harm. Now I am stuck here with more issues than I had before.
To be honest this is my work phone under a corporate account and I wanted to switch to WP7 but now I am starting to wonder if I really want to stick with a device that is having this many issues and on top of that the camera issues.
Im at a crossroads because I may just wait and go to the iPhone 5 when its released.

Well, at this point I don't know if I should get another Lumia since I'm still within 30 days, but I might try the Titan II instead...

I have this issue also. I reported it in a couple of threads here and on the Nokia site. I do NOT lose Data connection with Wifi. The Wifi connection simply does not display content. The site conneciton occurs. Sometimes the site theme or color shows up. But, no data is displayed. A reboot is required. I too tried 4g only connection for an extended time. Never had this occur. ONLY on a wifi connection, only at home, and strangely enough, only on limited sites. But, once the situation occurs, it occurs on every site until reboot.
The trigger sites for me....this xda site, and the old Twitter site. No other site seems to trigger it for me.
Since the update, this occurs much less. Before the update, maybe 1 in 15 Internet connection attempts at the those sites.

Just got my Lumia 900 swapped today -- to resolve some *major* issues I was having with the capacitive buttons + speaker audio. Anyhow...the button issue went away, so I'll see how the wifi/data issue goes. Hoping for the best!

I swapped mine out last night and now have gone about 15 hours without the Wifi issue. I'll keep everyone updated, but it might be worth it to swap out yours as well just for the peace of mind if your 30 days are nearly up as well.

No issues here. LTE and WiFI playing very nice together.

Same here. Swapped handset, no issues thus far.
If I make it through the weekend (with both DATA and WI-FI enabled) without having any issues, I'll be feeling pretty good that it was just a defective handset. Making it through a few days will be an even better sign!

Update: I swapped out my phone at something like 6PM Friday, and went all weekend and all work day Monday with no issues whatsoever with connectivity.
I'm pretty convinced that the problem is fixed, I think. I wouldn't wait around until after your return period is up if you're having this issue. I know it's a pain to reinstall all your apps, and you lose settings and game saves, but still.

For those that have this issue...or had rather. I wonder if you were able to narrow down a trigger. I do not have a data disconnection. I simply have a lack of content display. Not exactly the same thing. And, if it is not a data connection issue, we should probably not refer to it as such, because the researchers..or what ever you guy the 'official' people that look into it...could the issue off if it is indeed not a connection issue.
Anyway...glad you guys got yours working. I've had mine for over a week and only 1 occurance of the no display of content since then.....yes...triggered by xda.

I wish I'd paid more attention when this was happening on my (previous) Lumia 900, but I couldn't necessarily repro the problem at will. That said, it *did* happen on a daily basis -- sometimes just when opening my email and hitting 'sync' manually. It was almost like I hit 'sync' before the wifi was connected, and then it got into a 'disconnect' loop that could only be solved by 1) waiting for a few minutes, 2) going into Airplane mode and back to normal again, or 3) turning wifi on/off briefly. In any event, it would mean that ALL OF MY DATA did not function until I fixed it. I ended up turning off my wi-fi completely and just using my data connection for everything. That worked too.
All that said, I exchanged my Lumia 900 last Friday and I've not experienced this issue again.... not even once. I've visited the same websites, used the same email, sync'd the same way (sometimes manually, sometimes not), and I've left both my DATA and WI-FI on the entire time -- I never turn either of them off. Not one single "data loss" issue, or whatever you want to call it.
It "feels" solved. I hope it is

Curious. Same micro-SIM in the exchanged 900? Or, did they use a new one.

Yes. Sorry. Too lazy to trim down your post to quote. Interesting. So maybe it was a device problem. Or AT&T did some SIM configuring while you were there. Never get to see what they are doing on the terminals. In any case, good that you are up and running.

Well, to make a long story short, I switched to a Titan II, but had some other issues. With the Titan II I realized it was my fault, not the phones. I had switched to AT&T from Verizon because I has having the same issue over several phones that I had with the Titan II.
I really liked Mango, but with the inability to backup SMS/MMS messages, also the ability to send SMS from the PC (which can be done with 3rd party apps on Android), I decided to go back to Verizon. Hopefully when WP8 comes out we'll have these features, but for now, Android is my baby. Thanks to all who helped me, these forums are great for any phone.

No Network Signal After Flash to 4.1 on Verizon Galaxy Nexus

I just updated to 4.1 and can't seem to get a network signal on any of the ROMs I have tried. Anyone else had this problem or found or know of a solution?
Thanks.

Was this an OTA uprade? If you did an manual upgrade, you should make a backup before going forward.

Are you sure you used the correct ROM? Cross-flashing between a Toro/Maguro/Toro+ will often have the phone but up but with the radios not working

did you check your apn?

I just bought this phone on Thursday and the bestbuy rep had the same problem on two different phones and had to call the Verizon help desk. She managed to get it working and of course my signal went in and out as soon as I left the parking lot. I went home and immediately rooted and flashed 4.1 and had the same issue. I was on the phone with tech support and they couldn't find the problem.
I then did a quick search online and found that this is a common issue. The problem is that when updating to 4.0.4 the galaxy nexus has a hard time with the 4g connection. It then drops to 3g and then it realizes 4g is available and switches back just to start this never ending cycle. This causes a signal to be held for seconds at a time before dropping completely until it switches to the other.
The temp fix is to disable LTE and run your phone on CDMA full time. This worked for me and I have constant signal everywhere. Eventually I know a patch will arrive so I'm content with 3g for the time being.
What puzzles me is how come this doesn't happen to everyone? Its a big enough issue that I found the solution within 3min of searching for a fix but not big enough for Verizon to be aware of.

I have the same issue. it burns your battery as well by switching back and forth. I used to leave my nexus uncharged at night and the sleep mode would allow it to only lose a a few percentages but now if i leave 4g on with 50 percent battery.. Its almost alway dead when I wake up

Sad to say I have the same experience
The story told by mclaughlin47 is almost exactly what happened with me. Even rooted and running BAMF Paradigm 2.1, I still have the same problem. If anyone knows of a way to fix this, please let us know.
I can't believe Verizon isn't aware of this problem. I actually had better battery life and signal with my Thunderbolt running Vicious ROM. I may just be returning mine if I don't hear of a solution soon.
Thanks for any help, cause this is ridiculous!

I am rooted now, but even on stock ICS I was getting a problem where my radios just die. Requires a reboot to fix. But when I was seeing it, they always looked fine. You don't know they died until you try to use data or make a call.

Do you still have your imei

I saw the same issue with ics and jb roms. Tried several radios but always dropped data and voice when using 4g. From what I've been reading, it's a hardware defect.
Mine also works great and stays connected all the time when I leave it in cdma mode. Went back to my rezound since 3g mode there at least still let's me use data while talking on the phone. I like showering in as much radiation as I can

Reflash the radio and the cdma radio. Samsung and Verizon Wireless both claim that hardware defects are not known issues.
Which hardware revision do you have? (looks on the label on the back should be 11.11, 11.12, or 12.0.)

i have 12.01
will try reflashing the latest radios

Have the same exact issue...just upgraded to a jelly bean Rom and my data drops completely and I barely have a signal, did a super wipe (radio-rom-Gnapps)...and went to my old rom of ICS and I still have the same problem...but for the most part I barely have any type of signal and calls are dropping, called Verizon and they told me something about a switch, and that there is no problem in ur area....I just called last night, I'm gonna call back today...wish there was a solution ...also tried that 3G switch I just read earlier and I still have a poor signal

Any updates? I'm having the same problem

Hi,
I'm having the same issue. I've had my Nexus for about a month now and have had nothing but horrible signal issues, while my old Droid 2 gets fantastic signal.
I'm using the latest Bugless Beast 4.1.1 with the latest radios that were released today.
People have mentioned it being a hardware defect. I'm assuming I should just go back to stock ICS and go into Verizon and exchange it for a different Nexus?

It may very well be a hardware problem, but my thought was a SIM card problem for the reason that rebooting often does not solve the problem for me. I have a passcode on my SIM card, so if my phone doesn't ask me to enter the code then I can assume it doesn't see the card. This often happens when I encounter the loss of data problem and reboot, and I usually have to remove the SIM card and fiddle with it a bit and put it back in and then it reconnects.
So I went to the Verizon store to try and swap my SIM card and they wouldn't give me a new card, saying that it's a known software issue that Samsung has already attempted to fix twice and they are working on another OTA update. I obviously made a ruckus about how I'm paying for service I can't access and I want a different device, blah, blah, blah. Basically he was incredibly unhelpful.
I've been on ICS AOKP and recently switched over the CM10 JB and that's when the problems started for me, but I switched because some type of battery issue (it lasted about 3 hours for a few days) caused my phone to reset itself and erase everything so it seemed like a good time to upgrade. So I may have unique hardware issues going on but according to vzw it is software-based. I'm not sure if this is something that can/will be addressed in a new nightly if that's the case.

PEOPLE, IT'S NOT A HARDWARE PROBLEM! IT'S SIMPLY A RADIO.IMG PROBLEM! A LOT OF PEOPLE WHO IS ON ICS, BUT FLASHED LATEST RADIO ARE SUFFERING FROM THIS!
What you can do is just flash to a older radio image. Not that hard. Will this stop the OTA? Probably, but you can either flash the latest version back or just manually flash it.
Have a good day.

I got mine the first week of Aug at Best Buy. The first one I got had all the problems described above. Radios dropping out and dropping every call I made. I returned it the next day, and the sales guy told me he was 100% sure it wasn't the phone. I asked him to exchange the phone and the card because I couldn't use a phone that couldn't make calls. He did the exchange, and the second phone was actually worse. Most of the time, I could not even make a call. So, the next day I took that one back. They gave me a third one that worked great for a week, then I started getting a no SIM card error message. The phone would reboot and work again for about 3 hours, then repeat error message. I took the card out, wiped down all the contacts with a soft cloth, and I have had no problems since. Great reception, no dropped calls. Great phone. I don't know if it is hardware or software, but I would keep returning the phone until you get one that works!
Once again, what is the point of having a phone that can't make calls.

weak wifi transmission

I recently reverted to stock on my at&t note 2. I am having wifi issues. The phone gets a strong signal from my router (-50) but I get authentication errors connecting if I am not very close. Standing 5 feet from the router I get terrible throughput. I am running dd-wrt and can see that the router is only getting -90 signal from my phone. Every other device is much stronger.
I have tried disabling wifi power save mode and have tried the OTA update to ucamh3 baseband.
Any suggestions greatly appreciated.

With a weak or malfunctioning wifi setup over multiple roms ....I might suspect a bad antenna ??
Not a for sure thing...but it should be considered...
Several of these devices were returned early on with antenna issues...
With a pure stock UCAMH3 rom running...wifi has been excellent...
I would try a clean slate data reset in recovery...and a router reset as well...
Then set up the wifi again on the device...
It's a long shot...but is certainly a good first step in diagnosing the device and the antenna...
Does the device suffer the same in other wifi areas ??
If not...look back to your home system....g

Thinking it might be a bad antenna, I ordered a replacement housing which (to my understanding) includes the WiFi antenna on the Note 2. No luck. I'm going to try another ROM to see if I have any better luck. If that doesn't work, might buy a new router. I'll update if I find anything that fixes my issue.

I'm on CyanogenMod now with no improvement. Router sees strength of -85 and SNR of 9 when I'm 5 feet away from it.

exact same issues here with i317. wifi worked great for about a year while rooted, and running multiple roms. i loaded SkyNote4.3 and it's been down hill ever since. I'm currently on DN3 4.3 and it works fine if i am close to my router as well. have S4, and Nexus 7 on same router, and they work fine with great signal, so it's not the router. I even removed security from my wifi as a test, and same results.
I have tried reverting to 4.1.2 and still no change. Appears to be SNR related at the moment, as my other wifi devices have 38-50 SNR values on DD-WRT, but my i317 has 10-12. No microwaves or any of that jazz going on, all 3 of these devices sitting next to each other when pulling values.
still investigating, but if anyone has any suggestions i'm open to ideas at this point.
what has been tried: reverting to 4.1.2 stock firmware from sammy, 4.2 bootloaders, 4.3 bootloaders, different modems, different kernels, different roms.

I got a replacement Note 2 from AT&T for this reason. I Googled the problem and found many mentions of it, so I called AT&T and had the CSR Google the problem while I was on the phone..
Of course I hadn't opened it up or anything...

I sent my phone to Samsung twice. The first time they just tried to update the software and claim it was fixed. That obviously did nothing to resolve the problem. I just got it back from a second visit to the service center where they replaced the mainboard. I haven't tried it yet, but expect that solved the problem. I'll confirm later tonight.

yeah, i'm to the point where i believe it's antenna related, and I believe it's on the mainboard. unfortunately it's over my 1 year manufacturer warranty and att is telling me they'd charge me the 200 deductible and just replace it. doesn't seem worth it to me at all. it's just odd that it started out of the blue with a 4.3 skynote rom.

I thought mine was antenna related so I bought a new housing. That didn't fix it. I read where one person bent up the contacts a little so I tried that and it didn't fix it. I never used to believe software would screw up the hardware, but I really believe some firmware has a bug that's pushes too much power to the wifi transmitter and damages it. That's just a hunch from a few posts I've read. It sounds like this may have happened to people with a Samsung OTA update.
If I were you, I'd log onto Samsung's site and just double check that you don't have any warranty left with them. If not, I'd even try chatting with them expressing disappointment in the device. let them know that apple geniuses would take care of you anyways. Maybe they'll be generous.. worth a shot.

So good and bad news. After getting my phone back from Samsung the second time, wifi authentication issues and drops are gone. The strength is good enough to keep me connected around the house, and speed is fairly consistent throughout the house, and is good enough for browser, etc. However, the speed still isn't up to par with other devices. I'm now experiencing 4-5mbps on speedtest.net (vs. ~20mbps on my other wireless devices). :/
