Hi Larry,

thanks for the answer, here some more information as requested

AP infos:distance: 3m

Network card is built in into a Lenovo Thinkpad Edge

at this point there is according to ifconfig/iwconfig a connection
up and running, but ping tells me:
# ping

I tried with network-manager as well as without and wpa_supplicant
directly, no change.

Also removing the module and reloading it did not help.

See above.

I am running on top of default kernel git, will try wireless-testing, too.

Thanks a lot and all the best, and let me know what I can provide more!
