Wifi issue

Sorry if this has already been covered in another forum.
My wifi on the samsung mesmerize is not working properly, 3G works just fine. I try and go online from my wifi connection it says server problem, if I go to my wifi settings it says it's connected. Help would be much appreciated, I have a very fast internet and would like to take advantage of it, especially considering my psu just blew on the pc! I have pulled 10 mbs on this phone using wifi before. Haven't installed a new app that would prevent anything with the wifi that I'm aware of, just wiped my phone the other day, saturday actually. Again any help would be great.

We're going to need to know what you're currently running.
As far as I know, no one is having issues with Wi-fi on either 2.1 or 2.2

My wifi sometimes won't turn on and I have to reboot to fix it, try that?

Yea if that don't fix it try pulling the battery.
Although since the phone is telling you i'ts connected I'm now thinking this is probably app related...(which a reinstall or reflash may correct)

I also have wifi issues with my fascinate, running froyo. I turn wifi on, and it works until the phone sleeps. Then at some point (seem to be a different amount of time each time) I lose my connection to the net. It still says the wifi is connected (wifi symbol at the top). But if I attempt to use google talk, or pull up a web page I do not have access to the internet. If i turn wifi off, and then right back on, all is well (until the next time it sleeps).
There is an app called wifi keep alive. If i check all the options on that app it helps. I see the issue far less often, but it still happens, and using this app my battery life suffers a little.

Mobile data doesn't activate when wifi off

Having a real hard time withbswitching between wifi and 3g, anyone help? When I turn off wifi after a few hours of use, the mobile data wont come back without a reboot. I have tried cycling airplane mode, and it sometimes works and sometimes doesn't. Only way to get back is with a reboot.

does it happen regardless of where you are? my first charge had data issues, it would only grab carrier data 1 out of maybe 10 times i rebooted and/or turned wifi off, and when it did, it took hours. replacement device still has trouble reacquiring carrier data at my home, but it's fine everywhere else. fwiw, when i researched my issue, i saw tons of anecdotal reports of people having their sim replaced by vzw and not having any further data issues.

Thanks for the reply. It seems to happen regardless of location unfortunately. I am trying to use Llama or Y5 to control wifi but its not very effective when 3g wont come back on!

What have you done to your phone? what is your current setup? Maybe it's time for you to flash back to factory stock to see if the issue resolved and take it from there.

You don't happen to be using juice defender or something like that? When I used it, I was having all sorts of problems getting data to come back on. Ditched JD and all is well.

I use Tasker to switch between 4g and Wifi. I haven't experienced any issues even though I switch back and forth several times a day. Could your problem be a defective phone or the radio firmware? Personally I run a rooted Stock EP4D and have no complaints.

same experience for me when using Auto Wifi on eclipse.
no problems after switching back to Tweakstock

[Q] Wifi Problems

Hi,
Starting to lose my patience with this device now. Such as shame that this lovely piece of hardware is strangled by poor software. I've already put the device on ebay and withdrawn it because its so slinky and I really want the issue to be sorted. I have no option but to go with the ipad mini at this rate, it just works!
Using odin I've successfully upgraded to ICS with P6800DXLP8_P6800OLBLP7_P6800DXLP7_HOME.tar and XXLQ1_OXALQ1_ATO My wifi keeps dropping out, ive tried it on three different routers etc and still the same issue. Tried CM10 and that reboots on me. Ideally i want a stock rom that works without any niggles on my Euro p6800. Any ideas, i'm really trying to make Android work for me, ive searched the forums like a good boy but no real answers anywhere.
:cyclops:

I can't help but thinking... if you are fed up with the Sammy device, why not switch to something that is completely open, like the Nexus 7, instead of a closed ecosystem like Apple's? Seems like there are other (better) choices out there than the iPad mini.

I'm sorry you're having troubles. Please feel free to give me your tablet. I could always use two!
Barring that, here is what I would suggest that has worked for me:
I have always had "advanced WiFi lock" from the play store, and it appears to have improved WiFi performance even when I had ICS.
I had locerra's cyanogen 10 ROM for a spell and really liked it. I then did some research in the development section and found Daniel HK's Paranoid Android ROM v. 2.55 and have enjoyed it even more. WiFi performance has been consistent and stable on both custom. roms.
Do some research and have a go at it.
If not, i can give you my address as I am currently living in Mexico and you can ship it to me!

I didn't experience any wifi issues at all until today. I'm staying with a friend for the week in Canada, and wifi k3ps dropping out. It seems that only a restart will solve the issue, and the network then falls out of range(even though I'm next door to the router). I'll give the app mentioned a try.... But any other thoughts please let us know! I'm on the leaked ics rom from Open Austria, rooted.
Update: "Advanced wifi lock" app has solved the issue, thanks! But we shouldn't really need to download the app.. Any ideas of how to solve such issues natively?

Correction, sadly the app didn't solve the issue.... Still having intermittent wife but HTC is connected constantly.

Ensure you don't have BOTH 2.4 GHz & 5 GHz enabled on your router at the same time.
Use one or the other.
After disabling 2.4 GHz band, and using 5 GHz only on my Billion router, my device (P6810) had no wifi drop-out issue. Same if I use only 2.4 Ghz band only.
Hope it helps.......
BTW, I would suggest LP8, such as my SkyHigh ROM, having "fixed" wifi issue for most........ But try the above first

Did you fix your issue in the end? I've tried changing settings on the Cisco Valet router to operate in just one wavelength but there is no such option... I guess it must be a old router. The wifi lock app didn't make much difference either unfortunately.

Maybe you could check the router manufacturer website to upgrade its firmware.
Backup your router settings to PC first though...

Thanks, The firmware on my mate's Cisco router was out of date, wifi connection much better but it still cuts out and appears to only reconnect if I restart. Even a "quick reboot" from within Rom Toolbox Pro doesn't reconnect. Annoying issue... It even cuts out midway through a skype call with my wife (but no issues on mates ipad or my htc) Also no issue with my wifi connection back in the uk. Very weird. Any further ideas appreciated!

Just wondering of the connection is secured? Does it cut out on open connection?
If secured, did you restore wifi settings with any particular app (ie. Titanium)? If so, you could try delete/forget wifi connection and manually enter the password instead
Or, delete/forget wifi connection in settings and restore with titanium backup. You usually have choice of "101" or "XML", try one then the other, reboot each time after restore.
Edit: if you have another device to set up a wifi hotspot, open and secured, and test?

It's a secure network, but i've tried forgetting the ssid and then reconnecting, but it makes no difference... Still patchy connection. I don't want to make the network open as it's my mate's network not mine.
I downloaded an app called "wifi manager" and it seems to be working 60% of the time, which is good enough for the moment. When I get back home to my own wifi network I expect no connection problems as it was working fine when I left last week probably the issues were due to my mates awful Cisco router and not the GTab!

impression
I think it's the WiFi driver in the version of your ROM.
There is no reason you should be having to amend settings on a router because in most instances, you will not have access to a,ending the router.
I'm currently living in Mexico and I'm dependent on several WiFi access points around town and intermittent WiFi where I live. I can safely assume that the technology isn't the latest and greatest down here and I don't control any of those settings.
I am not experiencing the problems you are describing.

I think you're right, it is the wifi driver. I've just tried connecting to the open wifi network at Toronto airport, which connects fine on my htc, but i need to restart my GTab in order to connect to it. I'm running an official Samsung ics rom from the European carrier, Open Austria, (downloaded from samobile.com)... These issues only started when I left the UK and arrived in Canada. I'm wondering if the 3g roaming has some part to play in the error. Anyway.. I will try again when I get home, but anticipating issues.... How would I fix this? Do I have to reinstall the rom and all my apps?! (hope not, as I have this baby set up just perfect )

Maybe I overlooked it, but what is your current firmware?
Sent from my GT-P6810 using xda premium

Current firmware is the official ics from Samsung, build number Imm76d.xxlq2
Now I'm back home and wifi connects perfectly. I do suspect an issue of using wifi when roaming, but will keep an eye on it next time I go abroad again and post back if it happens again.

Ah, that says it all...
Check my comments about LP8 firmware mentioned in my first post here..... way down the bottom Was obviously missed. Posts after that, I assumed you had, since you didn't comment about it.
There is also a thread relating to the problem and the subsequentLP8 fix.
Either flash SkyHigh ROM (P6800 DXLP8) or official DXLP8.
Whether just flashing the kernel from DXLP8 firmware world do the trick, not sure, as I have a P6810. But as I said, flashing the firmware package helped most out with the "wifi bug"
Do you have root and custom recovery?

Just got my 7.7 3g P6800 back from Samsung in HK... Replaced Motherboard under warrenty due to super brick.
They installed LP7 ROM and when i got it here had wifi issues...
Read about it and found recomendations to change to LP8 Rom...
Now have installed latest LP8 Rom form sammobile
Wifi issues have gone away....For a week...Now back again.
Just dropping out every few minuets and not in range etc...
my ROM is
Baseband version P6800DXLP7
Kernel version 3.0.15-1160935
[email protected] #3
SMP PREEMPT Wed Oct 31 15:10:33 KST 2012
Build number IMM76D,DXLP8
Is there anything wrong with this ROM or could anybody recommend a fix or alternate ROM?
Thanks and Regards..

Possible solution to WIFI problems?
I have had major problems with WIFI in my 7.7. The Austrian ICS has dropped connections, went totally berserk in some locations and stopped working unless rebooted.
I have now diagnosed (I believe) that the reason is the use of channel 12 in any WIFI router. If the router does not use 12 there seems to be no problems. At home I can configure my router not to use 12 and after that I have had no problems. There seems to be some kind of conflict or the Tab is faulty in that sense.
I do not know if this can be generalized, but at least for me it worked.

Yes I had the same problem with band number.... My friend's router that my tablet had an intermittent connection with, was on band 11. As soon as I got back home to my router in the uk (which uses band 6) My wifi connection problems disappeared.

Yes I Can say after doing alot of reading i realised its the chanel.
im using locked chanel 5 and seems much better..also wifi connection manager from play store.
still not the greatest and low signal even in same room to router but working i suppose.
Just funny how my S3 has a much stronger signal compared to the 6800 every wifi ive ever used.
Would be good if somehow the wifi drivers from S3 could be used somehow?

WIFI stuck at "scanning for WIFI networks.."

Hi there,
I have a little problem with my HTC OneS after installing CM.
Everything works fine, but when I'm connected to my home WIFI and I'm leaving my house (or the WIFI idle time is over)
and I come back (or wake up the phone) it stucks with this message in WIFI settings, mobile data works well.
To solve this I have to restart my phone and then it works without any trouble, as long as I'm don't leaving my house.
All other WIFI work without any problem. The curious thing is, with stock ROM (and all notebooks and other mobile phones) it works well.

When it happens, try to turn standby on and off again: at this point wifi connects. Works for me!

[Q] Data once lost wont re-connect

i am currently using Resurrection Remix 5.0.2 but was using cm12 nightlys before. The problem is that
the data connection is good but once i loose the connection there is an exclamation mark next to the
signal bar so i presume thats the data lost. It then wont connect again untill i reboot the phone.I have tried
switching on and off data but still no joy..This never happened on kitkat. I thought the problem was CM
related hence why i tried the RR rom but exactly the same is happening. Someone sugested that it could be
the sim card but im not so sure as it works fine before lollipop.I surely can't be the only one experiencing
this? but by the same token i can't find any info on it either ..maybe says something!!
Hope someone can help as i want to stay on lollipop i do like it, maybe the official release will sort it out.
Thank you

It's a ROM issue (radio.img). I was facing same problem on earlier builds of BlissPop ROM, but not no issues..
If you are getting exclamation mark in 2 or more ROMs, then there is problem with your sim-card or the network operator.
I suggest you to contact your concerned network operator and take his help for the same. (If you are facing same issue on 2 or more ROMs, try out Stock ROM CM11s)

Thank you for your reply, so would it be possible to flash a modem from kitkat or would there be compatibility issues with that?

did you check your network type and apn settings

So here is the latest update. I replaced the sim card on Saturday, the problem is is still there. I checked me APN settings they are three UK so that's ok. I've tried cm12,resurrection, blispop and now I'm on sabermod. I'm thinking this oneplus doesn't like lollipop, looks like I will have to revert to kitkat for just now until the official release comes out but I can't see that fixing the problem either as I don't seem to see anyone else with this problem.
Thank you for your help folks

I'm also with Three and have lost my data connection. They replaced the sim on Tuesday and I'm sure it worked until the old number swapped to the new sim. I have a 321 simcard on order and I'll try that once it arrives. My phone is still running Kitkat.

I had no problems with kitkat, if it lost the connection it automatically connected again when I was back in an area with a signal. But this has got me beat, a new sim card and too many roms to count but still the same problem. I am a lorry driver and cover the whole of Scotland and signal is patchy at best and it's annoying to find out later on in the day that data was off and you didn't receive any messages or emails.. Some of them important..

I have exactly the same problem.
I'm from Spain.
I've discovered that if i set network type to LTE it seems to work right.
Today I've moved from blisspop to temasek.
The 3g reconnect doesn't work, as always.
I turn data and wifi off when I sleep so tomorrow I will confirm if LTE works also with temasek.

my connection has always been set on LTE but never makes any difference
At the weekend I installed the official OxygenOs, I have been driving all day and had to reboot the phone 4 times because of this problem, I did half wish that when an official release came it would maybe sort out the problem but no joy. So I can only think it's to do with the oneplus. I'm at a loss now and seriously don't want to go back to kitkat but it looks like this will be the only solution to the problem..

I've tested this night again and if I set network to LTE.
The test I've done is.
- Turn off data and wifi before to sleep.
- Turn off only data when I woke up.
The connection was successful almost inmediately.

Greetings. I ran into similar issue with the CM12s update.
Once I lose the mobile signal for whatever reason, the data connection is not restored. Only way to regain it, is by restarting the phone (haven't tested airplane mode). Sometimes even if I leave WiFi on for long time (overnight), I will not have data connection after turning off the WiFi. I use HSPA connection only, not LTE.
I can not recall having this issue on KitKat. Issue was on the first CM12s update and remains on the second one, both were installed clean, so clean install of the ROM will not fix it. I am not using any custom ROMs or kernels, only TWRP recovery.
Has anyone had such issue and maybe found a solution to this?

Did you ever get this sorted? I've been having this issue, luckily I always have Wi-Fi at home/uni but there are times when it just won't find a Data connection. This happened right after the CM12 update :/

Well decided to a bit of searching, if you go into Settings -> Mobile Network Settings -> Network Operators and manually choose the network rather than the Auto Search option, it seems to have worked for me for the time being.

I am on the same boat as OP. The problems started after updating to Lollipop.
If anyone has found a solution, please let me know. I read about someone installing a 44S modem, but I'm unsure if this will permanently change system files (I wouldn't want it to) and I'm therefore hesitant.
