WIFI Tether screwed up my 3G?? - Samsung Epic 4G Touch

During a recent power-outage today I needed to access the net on my tablet so I grabbed a wifi tether program from the store and tried to use it on my rooted E4GT. It did not work well so I cancelled the tether. Ever since that my 3G seems very un-reliable.
I tried restarting the phone, powering off then on again - no success.
I am considering re-flashing the whole FI27 onto my phone again but was looking for any other ideas.

[Q] Wireless Tether issues

Anyone else having issues with wireless tethering? I have tried multiple ROMS including Random 3.3, CleanGB 1.0.3, and SleeperRom. The hotspot Hack used to work brilliantly for me but about a week ago I started having issues where my ipad would connect for about 5 minutes on first start of the tethering, then after about 3-5 mins it would start flashing the connected icon (like it was connecting and disconnecting from the hotspot). Other wifi connections work just fine (example the one at my house).
I have also tried barnacle and wifi-tether beta 11 for root. Those don't seem to be able to connect at all. (Could not join network message for barnacle, connect briefly then disconnect for wifi tether)
Any help is greatly appreciated as I use the tether to watch hulu and netflix while at work and I have been bored the past few days.
Since it is on every ROM and every tether app, is it possible it is something in your Ipad? Never had a problem tethering from Froyo to CM7. Try Odining back to stock, root and tether. If it works there move forward testing at each stage. You may have bad data somewhere.

I thought it might have been the iPad also except that all the other wifi connections I have tried work like a charm and stay connected. I am at stock EI22 right now so I will get it rooted and try again to see what happens.
Are there any system logs or anything I can look at to see if the broadcast is going in and out or something on the epic?
You can try running logcat. It is an app in the market. It logs all operations.
Might have resolved it...
I did a clean ODIN back to stock EC05, then ODIN to a rooted EC05, then ODIN the CWM 5.
I flashed CleanGB 1.0.5 MTD and attempted to tether with default settings (enabling security) which i think defaults to WPA Tkip. that didnt work (connect then immediate disconnect then when I attempted to connect again it gave failed to join message.)
Finally I switched security to WPA2 AES and connected the iPad. it has been connected for a few minutes now so hopefully it stays connected.
Thanks for the help.
TLDR: Switch security on Hotspot Hack to WPA AES and tether worked.
Nice job! Glad you got it working.

[Q] Wifi Tether Apks NOT Working(?)!

Yes I used the Search feature, still no satisfactory resoultion...
I have rooted several phones over the past few weeks (with different bootloaders), Evo 4Gs, one tethers, one doesn't, Droid RAZRs, both tether, Droid 3s, neither tether (I read the TBH thread, so...), E4GT neither tether (mine included but am running Phantom's Rom so no worries there).
I am at my wits end. The apk(s) used to work before, but as of late I am not having any success at all. Android Tether lists in my networks, my pc and laptop will connect, internet access is detected, they connect but NONE of my browsers are able to connect.
I never had this problem, never had to change any settings in the apk(s), and never had to change my pc(s) configuration. Is this happening to anyone else? Does anyone know what is going on?
HELP ME OBI-WAN KENOBI!
Try FoxFi, free at Google Play. I had issues tethering E4GT. This app works great for Samsung & Motorola. All others, maybe Bluetooth.

Wifi Tether (Im using 3.1 beta11 pulled from Calk's ICS roms) works if you change the device profile to "Samsung Galaxy Nexus (CDMA/LTE)". I always enable the access control and allow the pc accessing.
The hacked sprint hotspot has always worked for me on gingerbread as well i prefer it but use the other atm on ICS.
Wifi Tether wont work properly until you change it to thet CDMA/LTE Nexus it gives the same issue you describe without the change.

Ok but what are you running ICS or GB because there is an answer to both.... If you are rooted the stock wifi tether works fine so can we have a little more info although the answers you have gotten so far a pretty damn good.
Thanks
I switched to my Nexus S 4G to give the ICS ROMS a spin and really loved it but missed my E4GT so I recently switched back. I am currently on Phantom's EL26 (Gingerbread) from way back when. I found that the EL 26 modem gives me the best battery life by far and I like the debloated stock because I am running SPB SHELL 3D launcher (cracked-pm me).
I have so many Google Wifi Tether apks on my pc and dug up the wifi_tether_v3_1-pre101.apk and changed the channel to 6. It works now.
The Sprint Hotspot comes fully functional on the ROM that I am on but it was really bugging me that I couldn't get the google wifi tether to work on friends' and family's phones. There must be a bug in the newest release or something.
FIFOX said that HTC has a block on wifi tether when I tried to install it on my friend's Evo 4G.
I am going to use the TBH thread to change the radio strings on my friend's Droid 3 so he can tether. We'll see how that goes later today.
-worked like a charm; rewrote the strings with RadioCom and changed the entitleent with sqlite editor, using the most recent google wifi tether apk on chanel 6.
Thanks for all the input. I'm gonna hit the thanks button for you all.
PEACE!

[Q] Is WIFI Tether working?

I haven't been able to get my wifi tether working. I've searched for hours but most of the post aren't very recent. I've tried adjusting the settings to many different combinations as mentioned in three other posts. I'm on baseband MC2, JB 4.1.2 and have tried two roms...Swampmonster 2.2/2.3 and Macks Allstar 5.0, as well as using both my PC and laptop to connect. I've used the TrevE mods that come with both roms as well as a couple of apps from the play store.
The same thing happens with every attempt, I connect to the AP but don't get any connection to the internet...DNS server is not responding.
I've recently changed from big red over to sprint and have had my N2 for about a week now. Is this a Sprint thing or is it just my unfamiliarity with my Note 2?
Any help would be much appreciated. Dexter's on tonight.....
Also tried WolfRom and USB tethering, still no connectivity

It's been working for me, basically. I'm on a stock deoxided MC2 ROM with Perseus kernal. I get an error but I don't know what it is, since the log gives another error about no file existing. The error I had before trying to reinstall WiFi and BusyBox was a routing fix failed error.
I used this at work for at least six hours to connect a tablet and laptop. I figure I'm using around 2GB to 6GB each night.
Unfortunately, you're going to have to keep experimenting. I suggest trying with just the defaults settings. See what happens. If not, try changing Driver reloads or none. Unfortunately, it's just a lot of trial and error.

Thanks. I don't give up easily...I'll get it working if possible. I'm just wondering if Sprint is blocking the tether because I connect right away with no errors but the "DNS Server is not responding".
I see you're from the bay area. I grew up in SF but haven't been back in a long time. I miss the beach...

Sprint should be blocking you unless there is something off on your phone. My issue, I think, has to deal with the BusyBox Linux binary library that got loaded. I'm assuming maybe a phone wipe and reflash may fix it.
Yea, I'm near the wine valley, actually. Although, I prefer to be back in San Diego.
I installed Goodness Noteworthy v1.0.8 ROM and get good wifi tethering of 3G. I haven't tested 4G as I don't get it yet.
I'm just running stock rooted MC2 with updated CSC data (Garwyn's) and the separate TrevE version of the Wifi Tether APK works like a charm. My kids just used it on 3G and LTE all the way down I-95 in Florida. Sometimes it would boot them all off when switching from LTE to 3G, but they'd reconnect without issue.
Not sure if that helps you, other than I'm using the very latest MC2 OTA and maybe you're still using a ROM based on the leak? I'm not a dev, so if I'm talking out of my posterior just disregard!
Got it working
I'm still not sure why I had problems when nobody else did on the respective threads for the roms I mentioned above.
I did get it going though...For the touchwiz roms I had to run ISWAT tether unlocker while my tether was active (It's on the Play Store).
Right now I'm running LiquidSmooth's AOSP rom and the native tether works great. I've been bouncing back and forth between nandroid
backups; I like TW most of the time but when I want to tether or am looking for speed/responsiveness I switch over to AOSP.
Just to make sure, have you tried this: http://forum.xda-developers.com/showthread.php?p=40234725
I flashed it on deodexed stock MC2 and it works great, even with tablets and an iPod Touch.
I got it working with Treve mod
WifiTether_TrevE_Mod_11_20_2012_insmodv3.apk
Had to change one settings, or else it wouldn't appear on PC
Change Device-Profile to Generic ICS/JB wlan0

I've got it working on deoxidized rooted stock rom. I'm using the latest beta from July 20, 2013 (TrevE Mod Wifi Tether. The only setting I needed to change was to Driver Reload 2.
wifi-tethering
Now, I'm also using the Wifi -Tethering . its still working now.
you can find info from rootnote2.com
Is the problem of wifi tether under AOSP rooms on this device totally insoluble?
I've never found an answer to it, only directions to fixing it under TouchWiz or vague changelog entries about having 'fixed wifi tether' on Carbon and such, which did no such thing.
Standard wifi tether app 3.3b2 fails to start an access point. TrevE mod claims to start fine in the app's log, but no access point shows up on a scan. The mobile hotspot function in system settings also starts up, and even let's devices connect, but there's no data transfer.
I understand that there's something bad going on with Samsung's release of wifi drivers, so I'm just hoping that someone somewhere has looked into this.

[Q] Reliable Tethering App?

I just rooted my EVO yesterday & I just can't get a tethering app to work. ONCE I had my laptop connect, but had no internet access. I've tried WiFi Tether several times with different settings & I can't get a connection. I'm just looking for a simple & reliable tethering app to use on trips & such. As far as I know I have the latest updates with no additional roms installed. Basically a rooted stock phone.

This can be a very tricky question that has perplexed many people including myself for quite some time! What I have found is wifi tether for root users is the best and most reliable but there are some conditions to this. What I have found is if you are a sprint customer you have to be sure to get the right version of wifi tether. It all depends on how much flexibility you want but if you want something reliable consider one of the early 2.0 releases instead of going for the latest and experimental one. The easiest way to determine this is to make sure that the little wifi icon is green and not yellow.
if you do decide to try to alter the sentence with the more advanced version, be sure to leave it on a generic mode with waln=0 instead of the specific evo 4G mode.
If you're using a rooted stock, a lot of the roms come with a built into hacked sprint wifi tether, so you should be all good to go.

[Q] Unlocked T999 t-mobile s3 on 4.1.2 jb tethering problem

Hello all, I just recently purchased a Unlocked T-mobile galaxy s3 that im currently using on straight talk. I have it rooted on the 4.1.2 jb version and cant find anything to help me get tethering working whatsoever. Any insight on what I can do to resolve this would be very much appreciated as im about to tear my hair out! Thanks
Try the tether apps from play store. If they can't help then see if your straighttalk plan prohibits you from tethering. As a last resort, you can switch to a AOSP Rom. All of these roms do have built in Tether that works the first time.
I don't do tether and don't use stock Rom, so can't help that well.
some time ago, i used an app called easytether. check it out.
easy tether and wifi tether
I've tried both easy tether and wifi tether, both to no avail, I can connect my computer to both but I don't receive data. Don't have this problem with my old galaxy s blaze. Even tried pdanet, same issue, does upload but no download for any of these. IM completely stumped at this point.
