Multiple Wifi adapter support

[tr3w]

Hi all.

I have a CX-919 with integrated wifi, but it's so unreliable I'm thinking about buying an usb wifi adapter.
The question is, will the two work under Android, or if not, can I make the external one default?

Does anybody tried something like this?

I'm pretty sure there are some supported usb cards out there, it has not been much of a question around here.

All i can tell you is to somehow disable one of them, they will only interrupt each other and affect air time.

I'm not really worried about finding a working kernel driver, but more about controlling the wifi from the GUI as before.

If i am not wrong (and i might be), most of the components are actually USB connections. I know ethernet is for sure, so even the bult-in wireless might be just that

as for supported wifi usb cards, i have not come upon a thread with that question so far. Wifi is not much of a touched area, been looking myself if i can tether at 5ghz and never found anything.

So you say it may not that simple to find a supported wifi adapter?

I thought it should be pretty straightforward to compile and use the standard linux driver for it...

I'm using external wifi dongle on 908.

It is not so simple, you need to completely rebuild SDK for correct integration. If you only build kernel module you can get some compatibility issues.

Thanks, I also found a couples of forums like yours, so it looks doable, even the GUI part.

I think I give it a try.

Здравствуйте!
Прочитал Вашу ссылку на пост, где Вы подцепили скомпилленный 8192cu.ko.
Имею донгл с 8192 и тоже хотел бы попробовать.

Пробовал сделать это у себя, на боксе с RK3188 на борту, не получается.
Что делал:
-переименовал имеющийся в папке modules анологичный модуль
-скачал Ваш зип, распаковал, положил в папку system/lib/modules
-дал права rw-r--r--(644)
-подсунул модуль в ядро imsmod /system/lib/modules/8192cu.ko
lsmod показывает модуль в перечне, но донгл не заводится.
Подскажите, пожалуйста порядок действий, как и че тискать и в какой момент вставлять донгл.
Про правку init.rc не спрашиваю.
Заранее благодарен,
Владимир
Sorry friends, was going to PM, but typed wrong buttons and sent my Russian message here

Manual for using self-compiled module with mk908:

1. Place module in modules directory
2. chmod 644, chown root:root (if you need)
3. Turn wifi off! check this with iwconfig, there shouldn't be any device such as 'wlan0'
4. insmod module
5. check iwconfig output, wlan0 sholud appear.
6. ifconfig wlan0 up
7. svc wifi enable
8. at my mk908 I need some times to make iwconfig in console, otherwise wpa_supplicant cannot connect to network, this can be corrected if we able to rebuild sdk.
You should not rename 8192cu.ko to rkwifi.ko, because ap6210 driver need to load firmware, and you get error wile loading, android gui set wifi to disabled state.



Answer in russian:
Добрый день, что показывает dmesg при подключении свистка? Если модуль загружен, то должен успешно считаться eeprom, появится что то вроде:

<4>[  457.024104] EEPROM type is E-FUSE
<4>[  457.024158] ====> ReadAdapterInfo8192C

там же будет информация о всякой ерунде, в том числе и о мак адресе. Если есть только информация по usb и драйвер риалтека молчит, значит либо не тот драйвер, либо криво подгрузился. Подключите свисток при отключенном встроенном вайфае, посмотрите в iwconfig появился ли интерфейс wlan0. Если появился, полдела сделано - драйвер работает. Кстати, какая версия чипа у донгла? Мой драйвер только под 8192cu, это важно, они все отличаются.

If anyone interested, I managed to build the driver for rt5370.

You can find also the script to install it on a running system. After running the script the wifi settings should work from the GUI (more or less).

After days it can disconnect (at least on finless 1.6b), usually a couple of "ifconfig wlan0 up", iwconfig, and turning off and on the wifi in the GUI in random order helps...

I use this script to enable wifi on boot:

#!/system/bin/sh
ifconfig wlan0 up
sleep 1s
svc wifi enable
iwconfig
sleep 5s
iwconfig
sleep 5s
iwconfig
sleep 5s
iwconfig
sleep 5s

iwconfig is needed because wpa_supplicant couldn't correctly work with non-stock wlan.

Yes, I have similar experience. Although it looks like I need to go to the wifi settings GUI to properly connect, at least after disconnect...

Someone with better understanding could put it into the ROM itself properly...
