MOD-WIFI-RTL8188 does not work!

[e-Ra]

Hi everyone,

wlan (MOD-WIFI-RTL8188) doesn't work on my A20-micro. I can't establish a connection.
But it should work with this image without installing external drivers or something else?

Thanks

EDIT:
Problem only occurs if eth0 is enabled at the same time.
If I disable etho in /etc/network/interfaces wlan is working.
What's the problem?

How does look the output of iwconfig? And the dmesg output without grep? (the initialization is missing).

It's a vanilla image, the only thing I changed is the name of the wlan iface (etc/network/interfaces) from wlan0 to wlan6 and adapted the ip, gateway and netmask settings.

It looks OK on link level (WiFi initialized and associated), so if the problem occurs only when eth0 is enabled, there may be something wrong with the routing, probably a incorrectly set default gateway. Try pasting output of route with and without eth0 enabled (the most inportant line is the "default" one).

It clearly is working, just not the way you want, so you just need to get used to the way Linux works.

Yes, it is working. The problem was a wrong default gateway setting. Thx
