Android with Wifi Thread - Cooler wifi

Update:
handsets are becoming very hot when wifi is used, you can make them use less power by using the rootfs.img provided, changes where made to tiwlan.ini during testing which keeps the wifi on active even when not in use, this version has reverted the changes and now power saving can be used once more.

Looks like this thread has served its purpose

Wow, are you actually doing all of these commands through the phone? >_<
I really want to see wifi rollin on android too, can't wait to load the ol' Tilt up with it.

the '-f' option
Hi,
a short question, you wrote...
Code:
'wpa_supplicant -f -Dtiwlan0 -itiwlan0 -c/data/misc/wifi/wpa_supplicant.conf &'
...and I've allready seen this in different ohter posts, but I don't know what the '-f' option effects.
I allready browsed the manpages an this option ins't listed. I just tried the command without this statement and it also worked (but did not create the output '-Dtiwlan0' to '/data/local/tmp'). But wlan also doesn't work...

For Polaris users who might need this info:
First things first, make sure wlan works in Windows Mobile. This seems to be the procedure for getting the wlan into do something in Android. It seems to be very similar to the wifi tethering guides on the G1.
Custom Kernel
We need a kernel, the kernel config produced by make vogue_defconfig ARCH=arm leaves the wireless extensions disabled, so this might the cause of the missing mac address in ifconfig. Current attempts to produce a kernel with these extensions have caused the settings dialogues and ifconfig to hang, Ctrl+C does not force an exit. I'll continue to investigate this.
Tiwlan kernel module
I've found another version of the tiwlan driver, other than the one that is currently in git master which loads the firmware and gives the ok - OK
Download Update: This driver skipped checks, ignore it
so lets see if we can merge this with the newer driver to get a working one.
Initial Variables
Code:
setprop wifi.interface tiwlan0
WLan Commands
Modprobe Method:
Code:
mkdir -p /lib/modules/`uname -r`
cp /sdcard/wlan.ko /lib/modules/`uname -r`/
Insmod Method:
Code:
insmod /sdcard/wlan.ko
Tiwlan0 Mac address: No
Required Output: TIWLAN: Driver loaded
WLAN_Loader
Code:
wlan_loader -f /sdcard/Fw1251r1c.bin -e /proc/calibration -i /sdcard/tiwlan.ini
Tiwlan0 Mac address: No
Required Output: Set property wlan.driver.status = ok - Ok
ifconfig -a might need to show a mac address at this point, i'm still not sure when ifconfig -a gets the mac address info
Code:
wpa_supplicant -ddK -Dtiwlan0 -itiwlan0 -c/sdcard/wpa_supplicant.conf &
ifconfig -a must show a mac address or the next step will error out, you can assign one using the following command, just change it to mac address you see in windows. However simply assigning one with this command might not be enough, it could be the sign of a bigger problem.
Code:
ifconfig tiwlan0 hw ether 00:00:00:00:00:00
Code:
ifconfig tiwlan0 192.168.1.100 netmask 255.255.255.0
ifconfig tiwlan0 up
Log Collecting:
Dmesg - Its a ring buffer so as new info is added old info will be removed, you need to run the command right after insmod or modprobe to see if it worked ok.
Code:
[B]dmesg|grep -i wlan[/B]
TIWLAN: Found SDIO controller (vendor 0x104c, device 0x9066)
TIWLAN: Driver initialized (rc 0)
TIWLAN: 1251 PG [B]1.1[/B]
TIWLAN: Driver loaded
If i'm right The kaiser has 1.1. the G1 has 1.2, its a reference to the chip used.
Logcat
You can run logcat at the start to keep a log of everything the machine has done since android has started. If you run it like this it will keep logging to the file as you run other commands so when you boot back to WM and sync you can open the file in an editor like Notepad++ and see what happened. This is the first thing i run when i get to the root shell
Code:
logcat -f /sdcard/debuglog.txt &
After running the wlan_loader you can run this to check it worked ok:
Code:
[B]grep -i 'wlan' /sdcard/debuglog.txt[/B]

i did once end up with the ok - Ok but it was hit and miss, and i've ended up with all sorts from ok - Fail to fail - Ok to fail - Fail but ifconfig has never shown a mac address on its own
Email to...
The terminal emulator in android should have an option in the menu to email everything you've seen to an email address, use that to keep logs of the entire session. Better terminal has this feature, but it stopped working, try
Files
Fw1251r1c.bin
The firmware filenames of the G1 and the Kaiser have the same name. So we should get a list of good kaiser firmware to rule firmware issues out as soon as possible. If you can connect in windows mobile to a wpa secured AP then the Fw1251r1c.bin in the windows folder on the rom should be the one you are using in Android.

thanks,
how did you manage that configMge doesn't fail on start? I still get 'rc = -1'. Did you build a new 'wlan.ko' with the Kernelsource from git (Vogue/Kaiser)? And what firmware are you using (the original or the extracted?)
maybe you can post your files for testing...

Its either the variable being set or modprobe being used that does the trick, so try those, i'm in the middle of compiling a newer kernel to see if it works better

Thx for the short Tutorial and the scripts. Unfortunately I still get the message:
Code:
'ConfigMge start rc = -1'
I think the reason is the (my) wlan.ko module - it shows following message/warning while loading (insmod and modprobe)
Code:

especialy lsmod gives me another value for the second number (think the allocated memory):

Upon further investigation it turns out that a specific version of the firmware and a compatible wlan.ko are needed to get it to work, i'm rolling up a fresh system.img to test now, i'll post it if it works

So you'll have to compile a custom kernel, then a custom wlan.ko before you try this. I have also uploaded the wifi firmware, a link is in the first post

Custom Kernel:
I use the Kernelsources from git ("git.linuxtogo.org", vogue branch). I also tried to build the 'wlan.ko' from Android-source (I set 'KERNEL_DIR' to the Folder of my Kernel source). If I run make I get some errors because of missing include-files.
//Edit: just made symlink to arm-msm
If I'm home on weekend I try to build a new wlan.ko for my kernel. Is there anything, that needs to be patched for kernel 2.6.25?
btw. I found this page http://www.johandekoning.nl/index.php, there are some information about wlan and firmware loading issues (for the G1, but nearly the same problemes)

I didn't do anything special to get a wlan.ko, just compiled it as normal:
Code:
KERNEL_DIR=/Android/kernel make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
Current status from error log:

Sorry, my mistake, i did in fact have a different driver version. I have uploaded it, check the first post. This driver does not seem to work and will need to be modified.

thanks for the files, where did you get them? Compiling worked without any failure (just had to create a symlink to 'arch-msm'
it seem as if the firmware is loaded (on my phone it only works with the fw of the G1). I think it is realiy loaded because you get 'failed - OK' if you try to load it a 2nd time.
by the way have you extraced wlan-eeprom ('/proc/calibration') http://projects.linuxtogo.org/tracker/index.php?func=detail&aid=32&group_id=37&atid=273

Yes, i have extracted my eeprom file and i have found my mac address in there 3 times, which seems strange. I found the area which has the same start as the carlibration of a G1 (found here) and extracted a chunk to get the same size file. I tried it but it doesn't seem to make a difference. Maybe the data is read after the point at which we are having errors?

So I've played a bit around with the files. At the moment the driver is loaded and the firmware is accepted. But the wlan adapter still doesn't get a Mac.
Btw. if you take a look at the eeprom-file you find the MAC from Offset 0x5C to 0x61 in reverse order. Would be interesting the G1 eeprom-file looks like. Maybe somebody can 'cat /proc/calibration > /sdcard/calibration.bin'.
//***OK nearly the same as you said - should write faster***//
OK, yes found the offset in my file, but the its a bit different
Code:
G1:
02 11 56 06 1C 06 01 16 60 03 07 01 09 56 12 00 00 00 01 0D 56 40

Ah, i made a mistake, still need to find where the contents of calibration are in the rom dump

Ok in romdump there are some more Offsets (0x243E5C8, 0x2500040, 0x2500840, 0x2520040 from full rom-dump) that have nearly the same byte order
But only in 0x2500840 and 0x2500040 my MAC is included --> I've checked with 'diff' both extracted Offsets (752 Byte) and they are same

Ok i found the correct location, I searched for 021156061c in the eeprom dump and found it. I haven't had a chance to test this yet. Also another interesting thing to note is that both the kaiser' and G1's mac address started with 00:18 :41

Good luck. I have flashed CROMI-X without problems. Have you cold-booted after the install/flash to see if that does anything? If not, try flash again after wiping cache/dalvik. Maybe someone with more experience will post as well. Wish I could offer more suggestions - I'm learning as I go.

Probably some left over settings from one ROM or the other. You must do a full wipe when switchingbetween the two. Did you try that?

Yes, have done a factory reset, flushed cash and dalvik, etc.
only thing I haven't done is wipe data (for obvious reasons).
In a nutshell, followed all the guides to the letter, but never get wifi.

Well unless you have a hardware failure? factory resetting should get it working.....BTW a factory reset in TWRP does wipe data so I'm not sure what you mean by not wiping data.... You need to wipe data as you'll have all your old data settings present. Back up in tibu the stuff you want to keep and wipe data please. What have you got to lose?

Yes, you are quite correct about wiping data. Leaves media though, as that's where the TWRP backups are.
So can confirm that I do a factory reset.
As mentioned in the original post. Everything comes up as expected, except wifi.

Still stuck without a solution.
Given that some of you got Wifi working on your TF700, maybe somebody can post the steps.
Only other difference I can think of is that my device is encrypted.
Thanks

Do you have external SD and willing to follow instructions? I will try to help you out and see if you can get your wifi back..

Yep. Have an external card, but not recognised by latest TWRP (still) if that's needed.
Happy to follow your lead.
Thanks

First, you need to format your external SD with a fat32 for the TWRP to see it. Then you may want to back up your whole system to your external SD just in case you want to restore it later. Also, you need to move all your data to your external SD because you will need to format your internal SD and install a fresh rom on it. Please make sure that you use a "Format" option in the TWRP, not "Wipe". After the installation of the custom rom, you need to shut down your device for at least 10 second and power it up for the rom to set up. When you see the device set up screen, you must let it stabilizes for at least one minute and reboot your device one more time. During the device set up, you want to skip the wifi set up and do not sign in the google app store to prevent any app to install. When your device are up and running, you can check to see if you can enable your wifi. Please follow all the steps and report back. Good luck.

[Q] WiFi connect possible, but no scanning?

Hi,
problem:
i can´t see any wifi networks, that im not connected to
i´m able to add manuelly any wifi network without problems.. wifi on those manually added networks, works perfect
notification of open networks is enabled.. and i got a notification that there is an open wifi network in range.. so scanning itself seems to work? but my device doesn´t show any network but the one im connected to.
EDIT: "MotoTool AIO" shows me at "SysInfo" -> "wifi" a wifi scan... so this seems really a problem on just displaying the wifi scan results on the device?!?!?
tools like "wifi analyzer" don´t show ANY network
what i tried/looked for, without a positive result:
wifi_display_on has still value 0 in settings.db
file WCNSS_qcom_wlan_factory_nv.bin is existing in /persists (http://forum.xda-developers.com/showpost.php?p=49656627&postcount=3)
flashed stock baseband (http://forum.xda-developers.com/showthread.php?t=2649763)
i did more.. but can´t remember everything.. im sorry...
im on latest gapps.. latest cm12 nightly.. (problem exists since some nightly in the summer of 2014)
im on moto g XT1032
i did not a clean install.. i just upgraded via adb sideload in TWRP (and i don´t really want to do a clean install)
after fixing systemUI Crash and launcher3 crash on myself (look: http://forum.xda-developers.com/showpost.php?p=58316659&postcount=768) i just have this problem (also no GPS Signal, tried to fastboot erasing modemst1 and modemst2)
im really really interested in finding the problem instead of just do a clean install..
so i also take a look at logcat.. and found those errors:

[SOLVED][Q] WiFi won't turn on

All of a sudden, on Stock + Root TF700T, WiFi won't turn on. I highly doubt that this is related to my WiFi router ... the WiFi won't even enable on the tablet, and I can't even see a MAC address in About Tablet section.
I also did some digging and have some additional detail, but I cannot find a solution.

And I searched the entire filesystem for "nl80211" and found nothing.
Does anyone have suggestions on where to go next? Did my driver somehow get deleted, or am I just not looking for the right thing?
Thanks.

I will use this question in the future as an example of how to ask for support properly. Unfortunately I don't have a solution for you, but you could check the files in your /data/misc/wifi, maybe you can find something unusual. Your MAC address should come from some file on the FAT filesystem on /dev/block/mmcblk0p5 - I'd recommend making an image of it as a backup and then analyze the image.

I provide Enterprise-level support to software devs working in the Cloud and particularly on CentOS/RHEL Linux servers. This is why I know how to ask for help properly.
Well, since I can't find much, and there aren't any definitive answers here, my next thoughts are:
1) Something is seriously jacked up on the filesystem, possibly corrupted driver, possibly something worse. Hopefully, this is the case, because a software problem is possible to fix.
2) The WiFi radio is permanently damaged, or "burnt out".
In the hopes that it's something more like software, I'm going to reimage. I just need to decide what ROM to use. Not having network connectivity will make the prep for this a bit more challenging, but I can work through it using a MicroSD card.
If it's #2, well then I suppose I will have wasted my time reimaging and will be on the market for a new tablet ... and I need to get on that right away because I need to travel soon. Any suggestions are welcome ... I'd like a 9" or 10" tablet and it must have an HDMI out (micro preferred) and be able to handle 1080p video.
Thanks.

[SOLVED]
I am having a heckuva time even doing what I described above.
-I had never unlocked the bootloader before, so when I tried the ASUS unlock util v8, it gave error "INSTALL_FAILED_SHARED_USER_INCOMPATIBLE"
-I tried the ASUS unlock tool v7, and was finally able to install it but when I run and select Unlock I get an error that there is no network connection (FFS that's what I'm trying to resolve!)
-I can't get into recovery, I just get the Android guy with "ERROR!" when I enter fastboot and select "RCK".
My only option is to go back to Stock. So, I tried this:
http://forum.xda-developers.com/showthread.php?t=1833212
The steps in that post result in the same Android guy with the "ERROR!" screen ... not a very helpful error msg.
So, I tried this, and used the stock firmware from ASUS. (NOTE: I downloaded "ASUS Transformer Pad TF700T Firmware: V10.6.1.14.10 Only for US SKU (Android 4.2.1)" directly from ASUS after I read their notes on where to check for which one you need ([Settings]-->[About tablet]-->Build number).):
http://www.transformerforums.com/fo...e-firmware-tf700-tf701-tf300-tf101-tf201.html
From that post ^^ I did Method B: Flash from MicroSD. I extracted the .zip I downloaded from ASUS, and renamed the new zip EP201_768_SDUPDATE.zip per the GUIDE linked above.
I put in my MicroSD, went back into fastboot, and selected "RCK". It was at this point that I began typing the above. Total time to get to this point was about 90 minutes!
-----
FINALLY, for the first time, I saw a progress bar under the Android guy, and he had gears turning in his belly.
*INSERT SIGH OF RELIEF HERE*
As I was typing out all the above, progress bars were moving, and a few reboots happened. I expected that I would be fully back on Stock ROM, and that my data would have been wiped. I never ran a data wipe, I just assumed the ASUS installer would do that by default.
Well, it didn't wipe data. But, what it did do: restore all my device drivers!! After about 10 minutes, and 2-3 reboots, Android loaded with my existing desktop and settings, and the WiFi connected right away!!
So, this fixed it. I documented the above so anyone (even me, months from now) having a similar problem might be able to use these steps.
WOO HOO!

lost root
I should add that I lost root now. I think at this point, after all I've been through with this, I'm just going to press on and install CyanogenMod which is what I was planning to do anyway.
