Is there a solution to wifi tether and 3g dropping off? - EVO 4G Q&A, Help & Troubleshooting

I have been using wifi tether and the built in tethering option on CM. On both my 3g will randomly drop in and out. Also, when tethering two computers the connection is almost unusable.
Is there something that I am missing or something that I need to change?
Thanks and I apologize if this has been answered. I tried searching without luck.

The only time that has happened to me, is when my screen went to sleep, because I had my m obile data unchecked. I have to force the screen to stay on during tethering. I used to have the tethering drop off as well, not the 3g. that was solved by changing the channel to 1. Never had a failed connection since then. Other than that, I would be rendered clueless.

Yeah keeping the screen on seems to help but I still can't figure out why the 3g shuts on and off. It is really strange.

This used to happen to me. I used it to play cod and I got a connection interrupted every 2 mins or so. Then i found wireless tether

Quick Pandora question

I don't know if roms have anything to do with this or not but recently my Pandora has started sucking. I am on fresh 3.2 and everytime I play a song it stops half way through and goes to the next song. Is this a known problem? Is there anyway to fix it? Thanks

I haven't experienced that nor have heard of anyone else. The Pandora issue I know of is the interference from the Stagefright code with Froyo. Do search on disabling Stagefright and see if that helps.

Are u using wifi when listening to pandora when this happens. It was happening to me on wifi only. 3g was fine. I reset my router by unplugging it and plugging it back in. The problem lies by either the data connection getting intrruptted or from flash.

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

I also just went over to my neighbors place and connected to his wifi just fine so I know my epic works

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.

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?

[Q] Stuck Data Issue?

Hey guys, got a question. Has anyone run into the issue of their data randomly getting stuck, with just the upload arrow illuminated? When I'm using the hotspot feature, this happens much more frequently.
Thoughts?
Dunno about a fix, but you're not alone. Happens to me all the time.

Yes! Wow I haven't seen anyone else mention this, but yeah I get the same bug on rare occasion.... quite rare.
Fix is to toggle airplane mode as this resets the radio. Juggernaut statusbar toggles ftw.

Yeah, I switch between "GSM/WCDMA" and "WCDMA only" when this happens. It's a real pain. I downloaded a 2.1-2.2GB program while I was at 4.44GB used and T-Mobile said I used about 30 megs as far as they know...seems to happen more when I get closer to 5 gigs, I dunno, maybe they're onto me xP

Leave network settings in auto mode and try enabling and disabling airplane mode. This always fixes it for me. I have encountered this bug on multiple devices after tethering. Happens less on the t989 because tethering is native (probably).

You get less disconnects using airplane mode as a fix? Interesting...it's always affected me no matter what pretty much
This happens all the time.. I've always thought it was quite curious.. seems like some "uploading" going on, don't like it at all..

I've never had it as a frequent bug... very rarely. Airplane mode just resets the radio.

I've had this happen to my T-mo SGII and Sensation...just stuck in upload and any other data requests (Web, email...) are null when this is occurring.
I wonder if T-mobile is probing our phones for information when this happens?
Either way, it is annoying and toggling airplane or data seems to solve...tho I've had it go right back to doing that today after toggling...

[Q] Can't receive MMS while on WiFi

Just like the title says. I'm using Wicked's V.5 with UVLI8. I've looked at other threads with other devices and I've seen no resolution.
Any ideas?

have you ever been able too? b'c on past phones while on wifi the mobile network would kick in to let the mms go Thru or come in then go back to wifi when it was done
Check if wifi calling is on. If it is turn it off and it should work.

Seems like a work-around. I'll test, but still, it's a pain to have to turn wi-fi calling off and on to receive a MMS. Why wouldn't I just turn of wi-fi for the moment till the MMS comes thru?
You can do that too. But for many its good enough to be a fix... If you're like me and don't use wifi calling.
I know it sucks, but at least you'll know what's causing it. Maybe if enough people complain they'll fix it.
I've heard some 3rd party apps allow mms to send over wifi and therefore will work with wifi calling.
Tmobile only allows mms to send over data connection.

Are you sure? I get pix all the time at home and I'm showing 100% without signal. 0 bars but still the triangle. This is with Wi-Fi calling always on. Stock and xquizit.
Sometimes I do get the "data roaming" lost connection bs and lose Wi-Fi calling.

Similar thing happens to me. Wifi get stuck or conflict with Data signal.
I always turn Network Data off 1st, then turn WiFi on - once WiFi fully loaded => turn data on. That way it prevent wifi conflict. Works for me.

You might be partially right lol. There was a thread about turning mobile data off and that killed MMS over WiFi. All I know is that I'm able to send and receive MMS at home and I have no cell signal. There's no way the MMS are going through the cell tower. Technically speaking I do have some sort of signal. Even though it says no signal it's a blank triangle and not the circle with a line through it. It's enough to register with the network I guess...
I think I need sleep too. Turning WiFi off gave me the no signal circle. So iono wtf.
I know this has something to do with the custom ROM I'm using (Wicked V.5). I've never seen this issue, and I've been using Androids for 2 years. Even before I flashed Wicked, I had no issues on the same device on the same WiFi network.
Xquizit xD works fine for me.

WiFi not reconnecting

I leave my WiFi on at all times. I only have WiFi access at home, so when I'm at work I leave it on but am not connected to anything except the cell network. My typical day is about 10 hours at the office. When I get home, occasionally I will reconnect to my own WiFi but most days it will show my network as available and that my password is saved, but I have to toggle WiFi on and then back on before it will auto correct. Trying to manually connect from the network list doesn't connect either until toggled off and on.
Over the weekend, I can leave for several hours and reconnect without any issue. Seems to be something with the extended time away during the workday that causes the issue. Is anyone else experiencing similar or have suggestions on how to fix this issue?

Just toggling the WiFi off and on seems to resolve it, so it's not an overly huge issue. Just would be nice if I didn't need to toggle at all and it would auto connect as my previous phones had done.
