Wifi problems

I'm on stock efo2 with ef10 modem
I can connect to 3g and 4g just fine but wifi disconnects as soon as it connects
Its not my router cause my iphone 3gs and nexus s can connect and I went to my friends place and tried his too.
My epic could connect before so I'm wondering what wrong
I don't think my modem failed

Changed channels on wifi router
Both my wife and I have Epics and they did the same thing a few weeks ago. Very frustrating when your 3g signal is weak at the house. My phone had been rooted in the past but I was back on stock for other reasons. My wifes phone has never been rooted. I decided to root my phone again and went to the EE03 modem and gingerbread rom to see if that would help. It didn't. I tried my old SDF rom from a few months ago and it was still the same. Finally I went in to our router settings (even though it works great with our wii, and both laptops) and changed the channel from 1 to 11 and now our phones connect great and stay connected. What really baffles me is that my phone wifi seemed to do the same cycling thing on other wifi signals as well. I haven't tried it at other places since it started working at home again. If I think of it I'll do that and post back the results.
So for me, changing the channel on our wifi router seemed to fix the problem.
Might be worth a shot.

Thx
Ill try that
Now time to google how to
Today after I left my house and left for work my modem just died so my phone was just as good as a brick
I just fixed it now
And as you said flashing modems dont help

damn changing the channel didn't work
I changed from 1 to 11
Still can't connect
Channel 8-11 are completely empty so wtf is wrong
I also just went over to my neighbors place and connected to his wifi just fine so I know my epic works

wow, im having the same problem too. I'm on EF02 modem with EC05 ROM (SRf 1.2)
I can't connect to my home wifi at all, but all of my electronics can....

Lets bump this thread until its a sticky or until we get our answer

Question... Do you have your settings for your Wifi router saved on your phone? ...My buddy was having this problem yesterday, and I told him to reset the settings and he reconnected and everything worked after that. It's worth a shot if you haven't tried it already.

Damn it didnt work

Try a different modem, like EF02, EE03, or EC05. Or something in your rom may have gotten corrupted. Try flashing a new rom and kernel. Wipe everything first. Or try a nandroid from before you had the issue, if you have one available. Not entirely sure these ideas will help, but worth a try I suppose.

I too am having wifi issues at home. I can connect elsewhere but my unsecured router at home will not let me obtain an IP. Rather than make a new thread I thought id try and post here

Bump and I guess the only solution is to buy a new router
Sent from my SPH-D700 using XDA Premium App

Fixed
What I did was go to cmd prompt
Type ipconfig
Take the number next to gateway
Paste that number into the browser
Google what your router's default password
Now find factory reset
That's all I had to do

how old is your house
I just recently moved & @ my old place I couldnt get my wifi to work @ all or even work on my xbox that was 5ft from the router & then i move out, dont change anything & like magic my wifi works perfectly on everything. i was told it was bc my old place was sooooo old it was made back when they used chicken wire to hold the "drywall mud" bc back then drywall didnt come in sheets it came in a bucket...

Not sure if this is the same problem or not.
My WIFI shows as being connected even when it is not connected. Thus, it appears that I am connected but data is in fact NOT working.
I tested this by choosing an encrypted wifi connection in my neighborhood and entering a random password. To my suprise IT CONNECTED! Nope, not really. it just showed like it was connected, it really showed that I had connected to my neighbors encrypted WIFI, but when I opened the browser to navigate I got nothing. Fooled me.
Any ideas?

SOLVED[Q]Wifi continuously scans even though connected

I am on Legendary 2.1 and just had it pointed out and I verified that even though my wifi is connected to my router it continuously scans every few seconds. This has got to be a battery drain. Is there a way to turn off the scanner when connected or set it for every 5 minutes instead? Thanks.
Edit: Thanks TeamERA for explaining that it only does that while in the listing window so it can update the list immediately. It defaults to the scan interval in build.prop when that window is closed. Thank you.

I think romtoolbox allows you to change that Im not sure but you can check it out.

Sorry root tools by jrummy allows you to change wifi scan intervals
Sent from my OG Epic

I'm pretty sure you should be able to turn off 'network notification' while connected...this should stop scans since this option is made to notify when a network is available. In theory, if its not notifying you if new networks are available, I would assume it's not scanning. Good luck

I found a program called wifi buddy on the Android market. This program allows you to disable wifi scanning.

I will try that...thank you! Probably add hours onto my battery life on weekends at home with wifi on.

Wifi buddy settings only control that app not the system settings so disabling wifi scanning only worked inside app not to system wifi scanning
Sent from my SPH-D700 using xda premium

I'm not knowledgable enough yet, but has anyone looked into using SQ Editor? Perhaps something can be manipulated in system files to just disable intermittent scanning all together? Only initial scan when wifi is activated? Just an idea...

That's what I was hoping for. Can't seem to get a DEVs attention to look into this. Build prop edit doesn't do anything.

Trying to find any sort of process or folders in root explorer that relate to wifi/scanning and coming up empty...I'm with you Kenny, we need a dev to pick this up, especially if editing build prop showed no results

I think my phone is doing this too.
In betterbatterystats mmc_delayed_work (under kernel wakelocks) accounts for 90% of my wakelocks, this does not happen on 3G so it is definitely related to Wifi.
I thought it had something to do with my router (DIR-655) as other people said they experienced unusual drain with that router.. Not so sure now.

This is probably the main reason people are complaining about their battery life on the gingerbread builds. I think it is more of a EI22 issue. How did EH17 or the previous gingerbread Roms handle this and if it handled this issue better can we take something from to fix our problem.
Sent from my SPH-D700 using xda premium

It would be nice to actually have the system manipulated, however, I am pretty sure that Juice Defender has an option of wifi control...I think (and I don't fully remember, just went to Thunderhawk and haven't put it back, trying to figure out other ways to better battery, as is everyone else) that you can allow JD to stop all wifi unless user selected.

So I don't claim to be a dev, but I just thought of something that might lead you in the right direction. I remember a post about lowering the signal threshold on your phone to get better 4g connectivity a couple of months ago in the general section. Its a dialer code and you need your msl to gain access. This is one of the phone settings like at the bios level. When I did this, I was able to see a boatload of settings that you would not find anywhere in the os settings. If you know where I am talking about and know the dial code to get in there, I do remember seeing some wifi stuff. Maybe something in there you can change scan or retry rates, with signal thresholds that might work for you. Write down all changes you make if u need to go back.
Again, just a thought trying to help.

You need to restore wifi calling settings via titanium backup. If u don't have, download a stock rom ands pull the apk from there

Copy the three files and put them in your titanium backup folder. Then restore the app

I was getting error ER05 and REG99 earlier today. I was able to get it working by disabling wifi calling (i had to wait a few seconds while it was trying to enable and was finally able to uncheck the box). Next i disabled wireless networking, then shutdown the phone pulled the battery out. Once the phone was off, I did reset my router, but I'm not sure whether the router is a factor. Once the router was back up i put the phone back together and turned on wireless, then enabled wifi calling. Worked with no errors. Before it started working, I did chat online with "support" and they said there were no outages in my area and that i should call tech support. My router is a Linksys WRT54GL

CM7 issues. (Dolphin browser, 4G, in-call sound)

So I believe I've had this issue everytime I fashed any kind of CM7 to my phone. The backup of my dolphin browser never actually restores correctly. All my other apps restore their data perfecty and work fine. But dolphin browser always just restores the app but I can never get my data back on it, so I lose all my bookmarks and saved emails and stuff which is annoying and sometimes I forget some of my passwords lol. But has anyone else had this problem? Even when I backup my bookmarks from the app itself and restore them it never gets me them back.
And the problem I'm having with 4G is it never connects or shows up. I know I need to have 3G on first, and I do, but when I turn 4G on it says "turning on" then "unknown" and it never even shows in my status bar as scanning or anything.
Also, the in-call speaker sound stays on the loudest even when lowerng it to the end. Its like that with regular talking on the phone and head phones, and no, its not from voodoo control. But is there anyway to fix this?

Tb. I always use it and it works perfectly on every other ROM I flash. Its just cm7 I'm having problems with. And no the backup isn't corrupted or anything. I'm thinking maybe it could be because dolphin runs differently on cm7?? Or has some kind of different data?

I can't imagine that the data would be stored in a different location. But you even said dolphin's own back and restore doesn't work on cm7? I would say that is a dolphin issue not a cm7 issue contact their support.

Ya that's what I'm thinking. Maybe it runs in a different way or something.
But anyway, that's not the biggest problem I'm having. I don't mind that as much as any of the other two issues.
4G, for some reason, just isn't working for me. Can anyone confirm that it actually works so I can see where the problem is from?
Also, the in-call speaker sound stays on the loudest even when lowerng it to the end. Its like that with regular talking on the phone and head phones, and no, its not from voodoo control. But is there anyway to fix this?

Not sure about the in call volume I can't test 4g seeing I don't have 4g where I live. Which version of CM7 you on? 7.2 RC2 is the latest version.

4g is working for me on cm7... or it was 2 days ago... not on cm7 right now so can't test... maybe they are working on towers in your area... they are starting deployment of lte and it has been giving their network some problems from what I've read... I know there was a big outage last week in texas because of this... maybe its that...

Maybe, or maybe not. Ill restore my backup of thunderhawk and test 4G to see if its from the ROM or the network. And I seen another tread talking about the in call sound to always being too loud so I guess that's a ROM based bug but not a big problem.

CM10 bugs....how to downgrade to ICS

I installed the cm10 rom about 2 weeks ago. I love jelly bean and cm10 dont get me wrong but i have been noticing that i can not send picture messages when connected to 3g or wifi (i have to reboot the phone everytime i want to send a picture) also my 3g would randomly disappear (it disconnects without showing that its disconnected). I have to put the phone on airplane mode and then reconnect to 3g. Just a few days ago my s3 stopped letting me use the wifi at my job (it said trying to avoid poor signal or something like that). The wifi signal at my job is very strong and i went into the wifi settings and disable the "avoid poor signal" feature. Still it wouldnt connect but it connects to the wifi at my house. I just want to know if im the only person experiencing this. Also how would i be able to switch back to ics from jb? Is it a quick process? Can it be done str8 from my phone without using my computer? Can i do it using mobile odin? If odin is needed?

So, now that you're back on ICS, you should give CM10 another try. That build was like 2 months old. Those bugs you were talking about have been squashed. Pretty stable at this point.
