I read the page too. I sure I do it step by step. But this error still exists. The files ( cfg , firmware , bin ) in the system before I copy in.Should I rewrite them ?
you have to do this steps after a clean (re)boot. if something went wrong => reboot
āfailed to init moduleā in first step can be currently ignored
if the files exist, you have not to replace them
Can you please share me the log(getting it by running dmesg)?
Thank a lot !
I have find my mistakes. āfailed to init moduleā and āCanāt open device node(/dev/stpwmt) error:-1ā should be ignore. When I ignore it , I can create my AccessPoint.
Hi hyh
Both drivers and tools for R2 onboard WIFI module are from Android system, and we donāt have time to remove unnecessary code so far. so maybe the driver is working fine but there is a few errors in log.
Thanks Gary
Is btif driver needed for wifi,too?
Googled aroundā¦it seems to be a kind of uart. Having actual Problems compiling it
Hi Frank
The BTIF driver is required if WIFI or BT want to be supported. I think there is no problem to compile it in both kernel 4.9 and 4.4.
Thanks Gary
R2 internal Wifi/BT (MT6625L) - Kernel 4.14.x/4.16 donāt understand the errormessage (wrong code in base linux code is implausibly). also the other with undefined param, wich i fixed it quick and dirty by defining it
@garywang can you try to close hostapd and restarting it? in my tests the ap does not came up (hostapd says it comes up, but its not visible on cellular)
user do some test for 2.4G & 5.8Gļ¼for reference only
5.8G test:
2.4G test:
Hi. I am using the Ubuntu 16.04 2017-11-28 image and facing the same problem like @hyh I am unable to connect wifi with my router even by using the steps from https://github.com/BPI-SINOVOIP/BPI-R2-bsp/tree/master/vendor/mediatek/connectivity
I can see that the wlan0 is up. But the wifi is always disconnected. Also tried this steps, https://github.com/BPI-SINOVOIP/BPI-R2-bsp/issues/1 But no success.
-TIA, Prakash.
do you want to use R2 as AP or as Client? @hyh tries AP-Mode, here you must āecho Aā and use ap0-device for hostapd
Hi Frank. I am trying to use as client. I also tried āecho 1ā. Still same issue. May I know what is the right steps to use it as client. The right top Network Manager on the desktop UI never shows the wifi devices near by R2 board.
Do you connect an antenna to R2 board?
without antenna you have very bad transmission qualityā¦if your router does not stand next to your bpi or you have overlapping wlans connect or scanning may fail
Hi Frank. I confirmed that I can able to connect my wifi router when I bring my BPI-R2 near to router. So its signal issue. I will use the antenna for better performance. Thanks.

Hello! Thanks everybody for facing problems with AP. Very good wrote here http://www.fw-web.de/dokuwiki/doku.php?id=en:bpi-r2:wlan#internal , as frank-w pointed. I set up AP according that reference. Now I have AP with static ip, also I need dhcp server run.

Believe it or not: I got ap0 running and I can āseeā my accesspoint. But performance is poor for only a couple of meters. I believe this is an antenna issue as I still use this tiny-little-plastic-whatsoever, so can someone please recommend an antenna solution?
I have bought a antenna with cable on ebayā¦
6dbi with rp-SMA To IPEX/u-FL cable
Simply search for thatā¦officially a 5dbi is recommended
