Base Android Networking Problem

I'm not sure if this is the correct place to post this, but it does have a direct bearing on what people will think of a rom.
Base android ie: not based on an HTC kernel has a problem with networking which will usually only manifest on wifi connections.
If you have a classless static route being pushed by the dhcp server then android will load that route but fail to load the default route. That will lead to you having no external network connectivity on wifi.
It took me awhile to figure out exactly what was going on because my home and work servers both have static routes to cater for on demand VPN dialing.
From what I can see the HTC engineers have patched this in their kernels because I only get the problem on AOSP roms, not on roms based on the HTC leaks or release versions. Perhaps some very bright kernel hacker (RichardTrip) would be able to figure out what they patched. The problem does not occur in the eclair stock rom.

I'm having the same issue with wifi on vanilla 2.2 roms. Currently OD 3.0.2 but have also had issue in CM6 nightly.
And as you mentioned, I've had no issue with sense roms.
Its different to the now fixed wifi sleep bug in that it stays connected to the AP just no data passes through?
And it seems some Nexus users also have this issue with their stock 2.2 roms also....

Hi wmobr,
it's easy to fix if you can modify the config of the dhcp server. If you can't then you have to manually add the default route.
You might be able to do it if you modify the rom to include a route update when connecting to wifi networks.

[Q] Can't make outgoing calls

When i make a call the call is immediately interrupted (after a short *bleep). Getting called works though.
I have done a full-wipe and using:
- LeeDrOiD V2.3.4 BETA 4 R2
- Radio_12.28e.60.140f_26.04.02.17_M2_SF - HTC WWE 1.72.405.3 R2
After some simple tests i found that wifi was interrupting the call. When disabling wifi i can make calls again.
I think i have the corresponding logfile (using adb logcat).
I am aware that the rom i am using is still a beta, but since i haven't (yet) found any other user having the same issues i decided to create this question thread. Who can give me some advice to fix this problem? Thanks!

When wifi is on, but not connected to a wifi-network i can make phone calls. Only when connected to a wifi-network, the call immediately gets disconnected after a short bleep.
Found only a single user having simular issues, only he runs on another ROM:
http://code.google.com/p/cyanogenmod/issues/detail?id=2732
E-mailed this person but we both came to the conclusion his problem was different and solved by a ROM update.
Attached is the logcat output. Three lines got my attention:
Code:
D/CallNotifier( 7167): - onDisconnect: cause = ERROR_UNSPECIFIED, incoming = false, date = 1300277007142
D/CallNotifier( 7167): - DisconnectCause is ERROR_UNSPECIFIED: play TONE_CALL_ENDED!
D/InCallScreen( 7167): onDisconnect: incoming: false state: DISCONNECTED post dial state: NOT_STARTED, cause=ERROR_UNSPECIFIED
Full-wiping again and installing LeeDrOid again didn't fix the problem. Installing CoreDroid V4 didn't fix the problem either.
Anyone got some advice how to fix this problem on the Gingerbread beta releases?

Just letting you guys know my issue is resolved, maybe it will help anyone later on experiencing same issues.
I found out not only disabling wifi will make outgoing calls work again, also changing the network settings from 'gsm / wcdma automatic' to 'only gsm' and reverting back again temporarily fixed the problem (outgoing calls were allowed again while wifi was enabled).
I Just flashed a new radio: Radio_12.41.60.19_26.06.04.14_M_Test - HTC Ace Gingerbread S Generic 2.16.0.0
Now everything is working as it should be! I thought it wouldn't be the radio as the issue was solved on an older rom with the same radio.
Edit: The problem persists. At first it seemed to work, but later on the problem came back. It looks like the Gingerbread beta contains a bug, but strange enough not effecting much people... Comparing the dmesg log with a dmesg log of a successful call pointed out that the next few logs are missing on a interrupted call:
Code:
[10894.955902] wds: 0020 @ 01
[10894.956024] qmi: wds: got handle 0x02a73d58
[10894.956542] wds: 0022 @ ff
[10894.956665] qmi: wds: CONNECTED
[10894.957977] wds: 002d @ 01
[10894.958068] qmi: got network profile
[10894.959259] rmnet_open()
Can anyone figure this out?

Isn't there anyone that can help me find out what is wrong or how to troubleshoot this furthermore? Can someone help me analyze the log files. The last thing i want to do is revert to stock and send the phone back for repair . Please advice!

I think it is a kernell/radio issue....

Yes it really looks like a kernell thing, now running excellent on LeeDroiD HD 2.2.2 with LeeDroiD's kernel 2.2.8 using radio 12.28e.60.140fU_26.04.02.17_M2. Still find it strange i am one of few experiencing it. That's the only thing that makes me uncertain about this being a kernell issue, as others should then have experienced simular problems wouldn't they?
I think i will just have to wait for a new (major) kernell release of GB.

Hey,
I am using CM7 and get this issue as well.
Sometimes when I call people all I get is a beep and it disconnects.
Switching to 2g works for me but that is not a good solution imo.
Wish I could get this fixed.

I am glad to see I'm not on my own on this one! 2g isn't a fix for me either, its a not-so-pleasant workaround. Temporarily disabling wifi was a faster workaround, maybe this works for you too. I went back to 2.2.1 because of this problem, maybe you should too.
Please keep me updated!

I always have wifi off when out and about.
Did you get stock rom or something? Post a link to the rom please.
I am just about to try cm7 rc3 - out today.

I installed RUU_Ace_HTC_WWE_1.32.405.6_Radio_12.28b.60.140e_26 .03.02.26_M_release_155891_signed.exe from http://forum.xda-developers.com/showthread.php?t=824357
After that i gained root and ENG S-OFF again, did a full-wipe and installed LeeDroiD HD 2.2.2 with LeeDroiD's kernel 2.2.8 (http://forum.xda-developers.com/showthread.php?t=842802) followed by radio 12.28e.60.140fU_26.04.02.17_M2 (http://forum.xda-developers.com/showthread.php?t=877295)

So what do you think I should do?
Go back to stock and stick with it?

That depends... I am no expert on this as I am on the same boat as you are. If this is disturbing you as much as it disturbed me you could give the ROM I am now using a go, that's LeeDroiD HD 2.2.2.

Well I am using CM7 rc3 for now with the latest radio.
I have also changed to GSM auto (PRL).
Will report back tomorrow.

did you set up an voip-account with your cellphone?
I am imagining a scenario like this: voip-Account set up and the option "use internet calls" set to "for every call" (may be called differently, my rom is set to german).
Now, if you enable Wifi, your phone would try to connect to your voip provider and if that fails for whatever reason you should be getting error messages...
If you have your phone sync your settings through you google account, that would explain the error reappearing after full wipe, new radio software and even on a new rom. Flashing a 2.2 rom would make the issue disappear though, as 2.2 doesn't support voip...

Thanks for your reply! Unfortunately this was not the case. There weren't any SIP-accounts configured. I also tested this by not configuring any synchronization accounts after fully wiping and installing a Gingerbread ROM.

Yesterday-evening i installed CyanogenMod 7.0.0-DesireHD and I did not have any issues. After that i installed CoreDroid HD GB 2.3.3 V5.1 but with that rom the problem came back. How did it go for you, you didn't report back.
So does anyone know what the similarities and differences between those two roms are? Both are running on Android 2.3.3 (Gingerbread). CM is No-Sense while CoreDroid is Sense. Are both using the same kernel? Could a difference in drivers be causing our problem? How can i find the drivers that are being used?

Have u checked your apn settings? I had to manually enter proxy and port after cm7 stable install for my phone to work.
Sent from my DHD

Yes, checked those too. At the moment happily using CM-7 without any problems, so as long i stick with this rom everything is fine. Not really a solution but at the moment very happy with this ROM.

[CM 7.1-11] [ALSO CM 7.2-RC0] wifi problems with peap-mschapv2

Hi,
it's a lot of time that I'm lurking the forum, especially the cm7 and ICS cm9 thread. Thank you developers!
I was using cm7 rc 1.5 and everything was just fine. Finally I decided to try the latest stable. Wipe cache and installed. Restart (and pull out the battery ).
Everything it's working fine, but the wireless, that was working on the previous version. Here at the university I have to use peap/mschapv2.
I try to deleted the /data/misc/wifi/wpa_supplicant.conf but nothing change. Actually after putting the information it looks like as before (but the priority):
Code:
ctrl_interface=tiwlan0
update_config=1
device_name=Motorola phone
manufacturer=Motorola
model_name=TI1271
model_number=1271
serial_number=012345
device_type=1-0050F204-1
os_version=80000000
network={
ssid="Wi-Fi_UniNa"
key_mgmt=WPA-EAP IEEE8021X
eap=PEAP
identity="[email protected]"
password="password"
phase2="auth=MSCHAPV2"
priority=1
}
The result is that under the settings --> wireless it just says "connecting" but it does not connect at all.
Catlog reports a lot of
Code:
wifi doCommand: ret=-1
I googled it, but I didn't find anything interesting.
Don't know if it works with other kind of connections. I will try as soon as possible and post the results.
Going back to rc 1.5 with a nandroid backup works good.
Here a full catlog (cannot put directly the link, new user)
pastebin.com/Hv1KWWVK
Do you have any kind of suggestion?
Thank you,
Peppe

So, the wifi works on a wpa-psk. Again, in the catlog there are lots of
Code:
wifi doCommand: ret=-1
so I guess this is not the problem.
Thanks,
Peppe

So it seems to be solved.
Yesterday, I first tried to copy the wpa_supplicant binaries from the rc 1.5, but nothing changed.
Then, I also copied the tiwlan_drv.ko (i.e. the driver of the wlan) and its firmware from Rc 1.5 and WORKED.
So to me it seems a bug of the wlan driver, though I didn't try to copy only the driver without copying the wpa_supplicant binaries.
I'd like to point out this to developers, but I don't know if they read this board (I cannot post on the dev board). What do you suggest?
Or should I use the github commits system?
Thank you,
Peppe

Could you maybe post a Link to the files from RC1.5 that you mentioned? Thanks

My wifi seems crappy though with RC1.5 :/...it sort of disconnects or loses activity (even though the wifi signal shows it's good)... It's very annoying when i play Modern Combat 3 multiplayer online --'

Unfortunately it's in german, but maybe you can have a look at it with Google Tranlsate.
There is a zip archive, that contains different versions of wpa_supplicant. I didn't test that yet, but I think it could be worth trying which one works:
www.gnuyork.org/download.php?file=wpa_supplicant.zip

To me, it does not seem a problem of wpa_supplicant. Or at least, the driver has something to do with peap/mschapv2, since it was working with rc1.5 and not with the stable.
Though we have eduroam in our university, it never worked (with laptop too). I've never investigated really, since I don't use it.

I gave my Defy to my gf recently so I had extra motivation to fix those little annoyances. I found out that if you switch WPA settings from AES (or auto) to TKIP it doesn't disconnect like that anymore.

Hi,
this is just to say that the problem is still in CM 7.2 RC-0. This time I *just* copied the driver and the firmware from CM7 RC 1.5 and now it works.
Can someone test the peap-mschapv2?
If the bug is real, and to me it seems, can someone post this in the dev section / cm7 dev thread? I cannot (low number of posts).
Bye,
Peppe

Hello everyone, I just tried this, and non of them work, the wifi just turns its self off after about 15 seconds with these wpa_supplicant-s. When I put the original back, it works just the way it always has.
My problem is that eduroam and the university wireless which uses almost the same protocols as eduraom just don't work. Its constantly connecting and disconnecting.
The wpa_supplicant.conf has nothing to do with this because i tried copying it form a friends phone which also has android on it (can't remember which phone it was), the bottom line is: it works for him, and not for Defy users.
Could someone please upload the rc 1.5 wpa_supplicant and tiwlan_drv.ko, because the link for rc1.5 is dead.
Also could you mention where to place tiwlan_drv.ko

Hi gmcgmc,
I can confirm the PEAP/MSCHAPv2 issues.
Beingi able to use my universities EDUROAM-network stopped when I upgraded from stock firmware to CM7. With CM9 it doesn't work, too.
I checked the different wpa_supplicants available via the link DD23 posted, with no success. With one supplicant it didn't even try to connect, 'cause it didn't store the entered settings. With some of the other supplicants it began to connect, but got an error during authentification. Maybe next week I'll be able to post a log.
I will give the driver/firmware thing a try.
Regards
kadolf

Me too having a wifi issues with CM7.2 RC2, it was working with my CM7.1 RC1.5 but i installed CM9 after that and it stopped working...Can someone help me fixing this please.

Just to make a resume.
Stock rom and CM 7.1 RC 1.5 work good with mschapv2 (at least for me ) while CM 7.1 stable and CM7.2 RC* don't work.
To my experience wpa_supplicant has nothing to do with this, as copying the driver from RC 1.5 works.
The last time I copied the following files (my guessing is that actually just the first file is needed. But anyway I copied all of them)
tiwlan_drv.ko --> /system/lib/modules/
fw_tiwlan_ap.bin --> /system/etc/wifi
fw_tiwlan_ap_rfmd.bin --> /system/etc/wifi
The right procedure (for me) was:
Turn off wifi
Delete (or rename to keep your passwords) /data/misc/wifi/wpa_supplicant.conf (rename e.g. to wpa_supplicant.conf.bak)
Rename the old files you are going to write
Copy the files (I used adb, you can use whatever you like)
reboot
Now it should work. If you want use the old wpa_supplicant.conf just delete the new one and revert the ".bak" while the wifi is off.
By the way, the last trick works always when the wifi is stuck (i.e it doesn't see any network):
turn off the wifi
rename the wpa_supplicant.conf
turn on wifi and check that it sees networks
turn off wifi
revert wpa_supplicant.conf
turn on wifi --> finished
No need to reboot!
I've two questions:
1. Can someone test if it is needed just the first file? If so, we may (actually I don't know how...) create a flashable zip
2. Can someone post this on dev thread?
Bye,
Peppe
PS: I've uploaded the files.

Hi gmcgmc,
thanks for the files.
Unfortunately I can't test them until next monday.
If I have some results (may they be good or bad ones) I'll post it.
Greetings,

Ok.
I've made a bur report through cm bug tracker
http://code.google.com/p/cyanogenmod/issues/detail?id=5313
So I confirm the bug/issue under CM 7.2 RC3. Copying *just* tiwlan_drv.ko works.
Bye,
Peppe

wpa2 issue
solved

I tried it with just copying tiwlan_drv.ko - behavior like before.
Then I copied the two other files, too - doesn't work for me and it stopped working with open networks.
I'll try to restore the original WPA-Supplicant, because I've overwriten it a half year ago (while trying to solve the problem) and lost my backup.

How did you copied it? I tried with RootExplorer and it didn't work. I had to use adb (after remouning system in rw). Something like that
Code:
./adb push "tiwlan_drv.ko" /system/lib/modules/
And yes, restore the original wpa_supplicant.

Peppe

The issue is still present in CM 7.2 Stable.

[Q] IPSEC VPN (tun.ko)

I'm trying to connect my phone up to my works Cisco VPN.
I've read online that I need a compiled version of tun.ko kernel module in order for it to work. I've checked in /system/lib/modules/ and can't see it in there.
There are instructions online for compiling it which I wouldn't mind doing but I'm guessing this will have to wait until HTC release the kernel sources for the One X(?)
Can I use the module from another phone running the same kernel version?
EDIT: Sorry just done some more reading and found out tun.ko is baked into ICS so this can't be the problem I'm having

Did you manage to get this working? I am trying to connect to a L2TP/IPsec PSK VPN and I keep getting a timeout.
This has been working for the past 2 years on my gingerbread Desire HD.
I think it's to do with this issue:

[Q] kernel(s) with wifi N support?

at firts i am running cm7.2_rc_buzz_kang(03-14-2012),with original radio(never had to flash another,just few times sometimes reflashed to make gps work),custom mtd
i would like to ask devs for this question, but i cant, so i try at least here...
some time ago our router at home has been changed and so has wlan...and that started to cause me problems,because i cant set router up for my phone to provide "g" wifi which works flawlesly..(actually,discovering,that everything is caused by "n" wifi provided by router was very funny,because it was the last thing i thought i could be ) however..after some googling and much xda reading i found app called Wifi fixer,which in most cases fixes my problem,but it doesnt work in 100% cases,and its not the "coolest" solution
few days ago i found Sympnotics kernel,and flashed it,one of reasons was its declared "n" wifi fix,which didnt work...i know,its beta,im not complaining,just saying what i found...btw thats the only thing,that is not good FOR ME on that kernel
so i thought to look for another...
i found infinityplay,which didnt work in "my" way,neither did "official" arco68s,neither last hcdr.kernel_v4.2...
the only one i found working is HCDR.Kernel_v4..
my next idea was (i am noob,so sorry... ) to copy bcm4329.ko (which should be wifi module of kernel) from HCDR.Kernel_v4 to SympKernV4.1..that (surprisingly ) didnt work...at least i tried...
so there is my question...(in this moment,youre the only person who i know is developing kernel,most for Sympnotic) would it be possible to have your kernel with hcdr.kernel_v4 wifi module??
if i have known to do this on my own,i wouldnt bother to ask here, but i have no idea how to build my own kernel,even how to take one,change wifi module and again make flashable zip...
sorry for my english,its not my native language
thx you all here
edit:i have the same problem with cm9,bulit does not matter...btw with hcdr.jacobs v4 wifi does not work...
