[Q] Loss of Wifi? - Epic 4G Q&A, Help & Troubleshooting

I just unbricked my phone by following the newest directions I found, you may remove that topic if reading this (sorry). Wifi was the issue I was trying to resolve when I did brick it. Ever since EH17, I downgraded (or tried to) to EC05 and get back on Syndicate, and now Wifi will not work except with DI18. Any update through Sprint, done from files from here, etc will result in non-working wifi. It always worked before, even with EC05. I have a Linksys E3200 with WPA2 security. Anyone have any ideas how to fix that? It always sits at "obtaining IP address"

I just got the phone back on EH17 in Syndicate, was still no luck (wasn't working in stock EC05 either). Now I go to EH17 Hurricane (where it last worked other than DI18 stock) low and behold, wifi works again! So how come now I can't downgrade to EC05 and still have it? What could be causing this?

Damn so many ppl are having this problem
I had a help req on this fourm with 2 weeks of bumping and no luck
But i figured how to fix it
Step 1 find your windows computers ip through cmd prompt
Type ipconfig
Your ip should be accross from gateway ip or something like that
Step 2 copy and paste ip into web browser
Step 3 login
Default password is admin
Leave username blank
Step 4 play with options till you can find factory reset or something like that
Step 5 press it
Step 6 ????
Step 7 profit

You are saying to reset the router. Unfortunately the router really is not the issue considering the phone can and will connect, but only with DI18 or EH17. Not even a stock (unroot start from scratch) EC05 will make the wireless work right. It just sits at obtaining IP.

Instead of doing a factory reset on the router, you could try just unplugging for 30 seconds and plugging it back in for a soft reset. It is possible an ip address is locked up or something in the router. Also for the changing of the modem, did you just Odin the modem.bin file? Can you explain the steps you did when upgrading/downgrading, etc...

Sure. I'll even go back to when I first rooted.
Was at Stock EC05, everything worked perfectly.
Rooted with Clockwork mod Purple, Added SyndicateROM Frozen 1.2 and Genocide 2.0 Kernel, everything worked great.
Saw ACS EH17Plus Kernel and Hurricane 1.5, decided to give that a shot, worked great.
Decided to upgrade the modem to EH17, used ODIN, did successfully. The only issue I had was the very seldom "random" reboot once going to EH17.
After trying for a while, missed a few features of Genocide/SyndicateROM Frozen. (Voodoo control, GalaxyTuner, etc etc). Wiped Data x3, Wipe Dalvik x3. Went back to that and noticed no wireless IP obtained.
ODIN modem to EC05, since I knew that worked, but no luck, still same.
Factory reset (after a brick somewhere along the lines, forgot where after) to DI18, wireless worked again!
Let Sprint auto-update to EC05 OTA, wireless stops working right again once at EC05.
Flashed up to EH17/EH17PLUS Kernel/Hurricane 1.5, wireless works right again.
I tried for the hell of it, to go back to SyndicateROM Frozen 1.2 and Genocide 2.0 but still, wireless will not work right.
So the only options that work for me are DI18 stock or EH17. Strange eh?
*Edit: I'm not even removing the above due to my own stupidity. I took your advice and soft rebooted the router, I don't even know how it would allow connection with certain software and not with others, but the phone is connected fine now on stock EC05. I have a COMPTIA A+ certification to boot. Sad day for me lol.

I am glad it worked for you!! It was probably just a simple IP conflict! And we ALL have days like this!

Yes, but the funny thing was I went into my Router's DHCP reservation before this and cleared out the lease for the MAC of the phone and it still hadn't worked! Once I noticed my printer was having an issue as well I figured something just got messed up in the router's memory or what have you. Once I did the soft reboot, everything worked thank god. It was just the strangest thing that the phone would connect using Gingerbread or it's original DI18 but no other setup. Guess I'll never have an answer better than a (at the time) dysfunctional router.

my phone did hang on the obtaining ip and on every build but other devices would connect
give it a shot
it worked for others too

[Q] 4g gone?

So, I started out with 4g working. I was on stock kernel with fresh rom. Then I did a backup and flashed cm6. Ofcourse cm6 doesn't have 4g, so because of this, i did a full wipe and went back to the backup. Then i flashed 2-3 kernels like kings, and netarchys. Finally i flashed bakedsnack kernel and rom.
So right now I'm on bakedsnack. BUT my 4g doesn't seem to work. When i enable it, it says "scanning" and then "connecting to sprint". After that it loops back to scanning, and then to connecting to sprint again. Over and over.
I know it sounds as if I'm not in the 4g area, but this happens everywhere and anywhere i go. Even if im 50+ miles from my home (where it worked previously.)
Does anyone know how to fix it?
oh and i actually have clear wire at my house, which has the same exact coverage as sprints network, and right now i have 4 bars on my clearwire.
There are several things that can be done to fix this. Try deleting the tree XML file first, forcing your phone to generate a new one:
Using a terminal emulator or through adb on your computer....
su
ls /data/misc/wimax
(You should see a file with your mac address - several numbers followed by tree.xml)
rm /data/misc/wimax/xxxxxxxxxxxx.tree.xml
Then reboot. Your phone will generate a new tree file when it boots back up. Flip on 4g and see if that fixes it.

Have the same issue good luck I havent found a fix other than a replacement phone
I have the correct mac I need I have certs etc etc
just reflashed it to start over. Seems to have teh same problem. Still have the 0016. Re doing it again now.
Same problem still, except now it does:
Scanning, connecting to sprint, turning off, turning on, scanning, etc..
sorry for the bump, but i had a nandroid backup of my old fresh rom with stock kernel. At first i wasn't expecting much when i restored, but i just saw that in the /data/misc/wimax dir, there are 2 xml files. One of which has my own hex (or w/e its called), the other one is 0016. I deleted the 0016, but it keeps re appearing. Is there any way to fix this?
I tried to adb remount it, but for some reason i cant. Is there another way to check to see if my rsa keys are still there?
Thanks
edit: I have now successfully changed my xml to the mac address, but 4g still doesnt work =/
I've had the same issue for a while now. I was on the 2.2 "leak" and it was still working. I used the roll back hack to get back and then went up to rooted 2.2. Since then, I've had nothing.
- My MAC was wrong, but the fastboot fix got that worked out.
- My tree.xml was wrong, but I renamed it and a new one with the right MAC in the name was generated.
- I went all the way back to stock unrooted (2.2 Final RUU) S-OFF and everything and still nothing.
I have mine sitting next to a friends and he's got 3 bars. Mine just keeps scanning, connecting and turning off then turning on (same cycle as the OP) without getting anywhere. I'll be watching this thread to see if there are any suggestions posted that I haven't seen in my searches. I think I've tried 4 ideas from other threads to no avail. If I don't get this worked out I'm going to have to visit the dreaded Sprint store and kill half a day waiting on them to test and most likely replace the damn thing but whatever.
Yea, im taking mine to the sprint store today. Tried everything. I cant even update it to 2.2 using the normal updater thats in the phone. Just fails at signature verification.
The problem is, I bought mine on craigslist, would they still replace it? Or am i ****ed?

[Q] Data network not connecting

Hi. Well I had rooted my phone and was running CM6.1.1 with snapdragon kernel. When the evo shift came out, I bought it and changed over to the shift. 3days in to using shift, the micro usb port failed and would not charge. It wouldn't even recognize when connected to my computer. So had to go and return it.
But when I changed over to evo, it started having problems with data connection. I could make calls but it would not be able to connect via 3g. It could connect through wifi but that was it.
So I unrooted my phone using .ruu and haven't tried it yet. Could you guys help me out and advise me in what option I have. Thanks again.
I had a similar problem when I had my hero....I lost 3g and ended up finding the solution was to wipe all, flash a sense rom and then go back to cyanogen....
Thanks. I'll try that and see what happens. I'll switch to evo tomorrow and see how it goes..
i had a similar problem with 3g data being very faulty after i updated all of my radios to the latest versions. what i did to fix the problem was full data/cache/dalvik wipe and then flash the radio: EVO_Radio_2.15.00.11.19, flash the wimax:EVO_WiMAX_27167_R01, and flash the PRI: EVO_PRI_1.77_003. Prior to that, i had the latest PRI and it would constantly screw with my data connection, so whatever you do, do not update to the latest PRI. Its actually been said that something weird is up with it and that this problem is common.
the radios can be found right here:
http://forum.xda-developers.com/showthread.php?t=715485
good luck man, hope this helped!
I have the same issue. I went from CM7 to a sense ROM and I still dont have date even after the new radio updates. Is there anything else I can do?
Have you already tried reverting back to your old radio that worked?
sure did. Nothing.
I actually did a full unroot using ruu. Then started my phone again back in stock mode. It worked after full unroot. Now I re-rooted my phone and back to using CM6.1.1 with snap dragon kernel.
Same Issue Please Help
Im having the same issue as the OP. I went from CM7 to a sense ROM and lost my Data connection. I can only connect through wifi. However I can't update my profile or my PRL This is a pretty big issue for me as I can't use any data features on the phone except when connected via wifi.
Can someone please suggest a way to re-establish my ability to connect to the sprint network. I do not have 4G in my area so I can't try that route. I have searched the forum for the last day and a half and still haven't found a solution. Ive tried reflashing the newest radios and still no luck. I have cleared the dalvik, cache and factory data reset mutiple times and I have tried sprint lovers newest ROm and also even tried reverting back to the original backup I took when I first rooted before I flashed any ROM's and still no luck. I also tried the ##3283#/MSL code/Data/ restore option and still nothing.
ANY Suggestions? Unrooting would be a last resort option followed by going to sprint and getting a new phone.

going to a sense rom, dialing ##data# and then entering your msl, then going to edit mode, top section, hit menu, and do a reset?
this usually fixes alot of data issues from what i am aware. It won't harm your phone anyway.
Yeah I have tried the ##data# restore multiple times and still nothing. It will reboot and begin the hands free activation but it never successfully completes it. Afterwards when I try to update profile it just sits in a loop saying "the network is preparing you services..." for 20 mins and then times out with nothing happening. I even tried the ##data# restore method again after reading this, for good measure, and still nothing.
Is it possible to connect via 4G and update my profile even tho I cant via 3G? I'm about an hour away from any 4G service I think Cincinnati may be the closest.
this is extremely frustrating and the worst part is that I dont know how it happened as I followed every instruction to the tee and Ive flashed mutiple multiple ROMS over the last 6 months and have had no problem until I tried going from CM7 to myn's warm2.2 rls5. After flashing the ROM and wiping EVERYTHING except the SD card I flashed the new Radio's (Cualkin's Combo pack with the newest Radios) and that's when I noticed the data connection was gone. I'm not sure as which step of the process caused the issue as I didn't notice it until I began to go thru the initial setup on the phone and was unable to connect to my gmail account.
I have backed up a few versions of rom's. Would they have the Data info I need and maybe a could just copy and paste a file or does this info need to be downloaded from sprint in order to setup the phone?
Please any advice??? I'd like to try all my options before I reroot and exchange it, If unrooting and returning is my only option can someone please point me to a good guide for the process? I used Unrevoked 3.21 for the root.

syndicate 1.01 no wifi

using syndicate 1.01 rom since thursday, everything running great,fast, etc... today i noticed it will not connect to my home wifi. keeps getting obtaining ip address message. had no problem connecting before today. is this an issue with the rom?
Sounds like it didn't flash correctly, reflash the ROM and if that doesn't work re-download it then reflash.
In the future look in the Syndicate thread and you'll see all the issues that are normal to know whether it was a bad flash or not.
i was just getting ready to re-flash but the strange thing is i put the rom on thursday and it worked with no problem for 2 days then just stopped connecting today. oh well i will reflash and see what happens
i tried frankenstein which is based on syndicate and still no wifi. looks like a common problem
Just to make sure, did you flash the EB13 Modem prior to Syndicate 1.0.1?
i used odin to put eb13 and victory pit. then i rooted cwm 3.0. booted in recovery and put syndicate on. i did not put the eb13 modem on.
is eb13 go on with odin on the phone tab? then boot in recovery and flash syndicate?
The EB13 Modem belongs in the Phone section.
no good on the wifi
boot in cwm 3
do all wipes
boot in download mode
odin eb13 modem
boot in cwm 3
do wipes
flash syndicate 1.01
flash syndicate fixhotspot,fixmaps, and fixtethers
still no wifi. constant "obtaining ip address"
i will keep looking but if any ideas please pass along
yep, same here. My wifi used to work perfect. Now, all of sudden out of nowhere, it keeps trying to obtain an ip address, but won't connect. My other computers connect to the wifi just fine.

[Q] Home Wi-Fi Will Not Connect After Flashing

I flashed Calkulin's GB ROM and flashed the latest FD19 modem. It wouldn't connect, so I flashed back to the EL29. Still no luck. So I figured, what the heck? I'll go ahead and flash an ICS ROM. So I flashed Calkulin's ICS and still no luck.
But wait, there's more!
I don't think this is a problem with the ROM. Why, you ask? Because I can connect to my neighbor's unsecured Belkin router no problem! Also, it's happened over two ROMs and three modems. And doubly also, I had the same problem with my Transformer. And tripply also, the thread for neither ROM is lighting up with people having this problem.
I'm using an AT&T 2Wire, so to fix this, I have tried the following:
Change the broadcast channel on the router (this is what solved the problem on the Transformer).
Change the IP range on the router.
Restart the router from a browser.
Physically unplug the router for a few minutes.
Disable and then re-enable wireless from the router.
Someone suggested clearing the DHCP table, but I don't think you can do that on a 2Wire.
And... still no luck. I have to believe that this is not all that uncommon.
Has anyone else dealt with something like this?
For the record:
Calkulin's E4g 2 v1.4
Modem: EL29
Kernel: 3.0.15-SPH-D710.FD02-CL336391
Again, I don't think t's the ROM.
Is your network password protected with WEP or WPA? If it is then delete the network from your phone and add it back. Should connect after a minute or two. I have to do this pretty often when flashing between roms.
If you've already done this then I'm at a loss.

This may be a silly question but have you setup the connection again? Every time I flash a new ROM I always have to search for the network again and re-enter my password.
Verify the Password
Well, I decided to try one more thing and disabled network security. Voila! Connected in less than a second. So then, when I turned network security back on, I remembered that I had recently changed the password.
So here's my word to the wise today. If you're having trouble connecting to a Wi-Fi network, make sure you're using the correct password.
Thanks for the replies, though.

Kindle 6.3 Broken Wi-Fi

I recently came from ICS, and having issues with wi-fi there. So I went back to stock, hoping my issues would be resolved. Awesome. They aren't!
Wi-Fi doesn't work. I have/had hashcode's latest kernel flashed. I don't know what to do. Any ideas? D:
Any help is appreciated.
Thank you!
How are you wiping when you flash roms? Maybe you have messed up how your kindle connects to wireless . There has been a Mac address issue with the new kernel maybe yours never reverted when you went back to stock. Have you tried other networks? Have you done a factory restore? Do you mean pure stock not rooted?

I wipe ; Factory Reset, System, Dalvik-Cache, Cache
And basically when I go to TURN-ON Wireless, no networks show. It doesn't even fully turn it on, it gets stuck in the middle of turning on the Wi-fi.
I went back PURE stock, NO ROOT. However, it seems I may have need of getting ROOT back. :/
I'm still curious if you performed a factory restore when you returned it to stock. I suppose your case could be that something burned out the wifi adaptor of the kindle although I bet its rare but not completely unreasonable. After a new clean flash when you reroot we will see those results ?
Probably totally unrelated, but have you ever had the locate-my-kindle software installed? I got similar weird behavior after a while when using that... first wifi networks were slow to come up, then it would struggle to turn on wifi, finally it'd just give an error and crash the settings manager or whatever it's called. I had to get rid of the software. Basically it was storing every single wifi network it ever came in contact with, even for just a second, and having too many entries hosed wifi. Uninstalling it seemed to clear those extra entries and restore functionality.
I do know that restoring your account from Google to your device and letting them keep copies of your wifi passwords can also cause issues although when I was testing roms for some devs on my droidx with known wifi issues ñot allow the Google restore and backup caused similar problems.
