Stock rooted Froyo: VPN broken - EVO 4G Q&A, Help & Troubleshooting

After flashing netarchy's stock rooted Froyo ROM, I can't use my VPN anymore. I have a L2TP/IPSec VPN server and it's working fine with my laptop, and was working with my EVO before Froyo. Now, the phone connects to the server with no errors on either end and the connection is successfully established. But that's all. No data is ever sent and I can't connect to anything behind the firewall. At least one other person is having this issue:

It doesn't appear he is using a rooted ROM so it can't be an issue with netarchy's ROM.
Any ideas?

I'm having a similar issue.

[SOLVED] Cannot Obtain Ip Address

After flashing the latest Radio and ROM from DJDroid, I have been unable to actually connect to my WiFi. I have since then flashed LeeDroid's ROM onto my Desire, and I am still unable to connect to the WiFi of my router. Now I was fine before I flashed this new ROM, so I am unsure what has happened. Does anyone have any suggestions?

Would you mind sharing how you solved it?

[Q] Wireless Tether 3G Issues

I have searched XDA and SDX to no avail. I seem to have opposite problem of everyone else in that Wireless Tether (2.0.5-pre8) will only work on 4G, and not 3G. When I try to connect over 3G, the network appears on my PC and I’ll get notification that network is connected, but it doesn’t actually connect to the internet. After a few seconds an error will pop up over PC network icon reading “No Internet Access.” Tether works flawlessly over 4G however.
This is my current setup:
Latest Build: 3.30.651.3 rooted odexed
Kernel: [email protected] 18-2 #17
Latest Radio, WIMAX, PRL,PRI
I have tried almost all of the different versions of Wireless Tether with the same results. And I know WT used to work over 3G, but I have flashed so many different ROMS/kernels I don’t remember which setup allowed this.
Native Hotspot app shows 67 registration failure over both 3G and 4G
have you tried the pre13 release? pre8 is old
wireless_tether_2_0_5-pre13.apk,
http://code.google.com/p/android-wifi-tether/downloads/detail?name=wireless_tether_2_0_5-pre13.apk&can=2&q=Evo
Yeah, that's one of the versions I already tried w/same results. I suspect problem lies not in tethering app, but somewhere in my phone.
when your computer is connected and showing no internet access does your phone have access at that time?
are you using juice defender?

Try Calkulin's USB tether fix. You can look it up here http://forum.xda-developers.com/sho...ghlight=Calkulin's+USB+tether+fix#post8795414
post #356 or download it here
http://www.mediafire.com/file/4y1l9c6ydg7027r/Calkulin's_EVO_2.2_USB_Tethering_Fix.zip
I do run Juice Defender, but have disabled it with same result. As far as phone still having connection while PC does not, I haven't checked that part yet. I'll check that tonight after work.
I thought Calkulins Tether fix was for deodexed ROMs only? That was going to be my next step, d/ling deodexed version of my existing ROM and applying this fix.
Is it possible latest HTC kernel is culprit? And this raises another question: I thought a modified kernel (with ip and binary files?) was necessary to run WT? How is it I'm able to tether through 4G on supposedly stock HTC kernel?
Here is link to current build:
http://forum.xda-developers.com/showthread.php?t=836728
I just checked, and phone does still have 3G connection while PC does not,i.e., I can surf the net on native phone browser while PC cannot. It just shows "limited access" above PC wireless connection icon.
Thought I had it fixed; I was wrong.
You don't have user access control on blocking your pc?
Try the deodexed version wifi and then usb tether.
Have you tried custom roms or are purposely staying with 3.30.651.3 builds?
NOW I fixed it:
Restored Nandroid backup of earlier odexed 3.29.651.5 build with [email protected] #10 and WT works as it should on both 3G and 4G.
Hopefullly this thread will help anyone else experiencing similar with latest build and kernel.
Thanks to all who responded!
I have been having the exact same problems, so now im currently trying to find the 3.29.651.5 build with [email protected] #10 since i didn't do a backup.
It seems to be a problem with the stock 3.30.651.3 build.
(~-_-)~
I think this is the one I originally used
http://forum.xda-developers.com/showthread.php?t=819838
Disregard Earlier This is the One
http://forum.xda-developers.com/showthread.php?t=699847
This ROM incorporates the latest Software version 3.29.651.5 with some developer applications (root, busybox and flash_image).
Updated kernel to 2.6.32-15-g0f673ed ([email protected] #10)
FWIW, I am using Wireless Tether 2.0.5-pre8 and am getting d/l speeds of 4-5 mb/s and u/l speeds of 1-1.2 mb/s over 4G on my PC, so I see no need to try a later version of WT.
YMMV, but if it works this well, why f**k with it?
But see my related post
http://forum.sdx-developers.com/index.php?action=profile;u=2063;area=showposts
I haven't been in area w/o 4G since latest tweaks, so I don't know if above will still break my 4G connectivity as described in above post. Just be sure to have a Nandroid b/u through Amon Ra 1.8 so you can restore your 4G if above breaks it.

[Q] Rooted wifi tether stopped working?

Hi guys,
The first thing I did when I got my Nexus is root the phone and install the wireless tether for root users. It worked fine the first few times I ran it, but now whenever I hit start tether it starts up and mentions I should check the error log. At this point the tether has failed to broadcast a network even though the app thinks it's working, and everything is ok in the error log except these 3 steps:
Setting ad-hoc mode
Setting essid
Setting channel
These 3 flag as failed, I have tried other wifi tethering apps and get basically the same result where they won't start up or they start but fail to broadcast.
My wifi works fine, I can connect to networks via wifi without any issues, but I'm really stumped as to why the tethering has stopped working.
Anyone have any ideas? I'm running the stock ROM still as root while I wait for a good port of the forthcoming CM9, so if someone wants to suggest a stable, fully working ROM to flash in the meantime that's fine too
An update, I flashed a couple of different roms and this issue has now persisted accross all of them. Nobody has any experience with the same problem?
do you have the most recent version of wifi tether?

As far as I'm aware yes, it is also failing to work with other wifi tethers (have tried barnacle tether which does exactly the same thing)
I'm starting to think it might be hardware somehow, but other than this the wifi works fine for connecting to networks.

PPTP VPN issues- possibly solved

I've searched far and wide for an answer and I can't find anything conclusive. I'm trying to use a PPTP VPN connection on my phone SGS II. The connection requires MPPE encryption and I can connect but afterwards the connection fails/drops/timeout after about 3-4 minutes. I am on ICS 4.0.4 (darkside). Does anyone have a conclusive answer to why the VPN connection will drop when I am in an area with full service? I have tested all the radio's available and deduced it is not a service/radio issue. It seems to be possible an issue with the kernel, or ROM, but again I am not sure. I'm at wits end trying to get this to work.

Here is an update incase anyone experiences the same issue.
In my testing I re flashed the darkside ROM I had a few times to be sure it was not a dirty flash. I also switched Kernel's from tdj's to faux. Neither step worked. So I flashed a new ROM (infamous resurrection) it comes with its own Kernel as well. After flashing IR I have been able to maintain VPN connections via PPTP w/ MPPE encryption. I can't conclusively say if it was ROM or Kernel related but my issue is resolved. If anyone is ok with ICS and needs to use a VPN connection the Infamous Resurrection ROM is the one I'd pick.

Wifi hotspot does not provide internet access

Hello, I once had a problem with the wifi hotspot operation on a Lenovo K3 Note - while the data connection worked fine and the hotspot set-up appeared to work, the connected device did not have internet access. This was solved when I flashed a new ROM.
Now I have an identical problem on an elderly phone (Ice-phone mini) running Android 4.3 that I want to use as a wifi hotspot. The symptoms are exactly the same as I had with the first phone. This phone is rooted, but I have not found any other ROMs to try, it is running the original rom.
I wonder whether this wifi hotspot problem is somehow generic, as I have come across it on more than one occasion. Is there any generic, or other solution?
I've tried Wifi Tether, but for some reason it fails. The log shows wifi interface configured but all the other operations fail.
Thanks.
