Reg: Access point association gets down with in 5min for MARVELL_SDIO_8688_WLAN_CARD

[praveen]

Hi All,

I am using MARVELL_SDIO_8688_WLAN_CARD with PXA270 based reference board. I 
used the patch available with this list for 8688 card. 

After inserting the modules I get the following debug messages

[root at REGULUS /tmp]#insmod libertas.ko
[root at REGULUS /tmp]#
[root at REGULUS /tmp]#insmod libertas_sdio.ko

Scanning the access point using iwlist gives following prints. In this all the 
channel and bit rates are wrong. I don't know why?

[root at REGULUS /tmp]#./iwlist eth1 scan
Warning: Driver for device eth1 has been compiled with version 22

I established the link with one of my access point using following commands
ifconfig eth1 192.168.6.165 up
./iwconfig eth1 mode 2
./iwconfig eth1 essid "econAP1"
./iwconfig eth1 enc "s:ca188"
./iwconfig eth1 key 0123456789
route add default gw 192.168.6.1 eth1


After giving above commands my board get associated with the access point. See 
the output of below command

[root at REGULUS /tmp]#./iwconfig eth1
Warning: Driver for device eth1 has been compiled with version 22
of Wireless Extension, while this program supports up to version 17.

But with in 5min board lost the association with the access point. Please see 
the output of iwconfig once after association get lost
