Issues with Samba and WIFI

I noticed that if I use my WIFI all the standard network problems occur (3-4 min dropouts, minutes before you can see shares). If I switch to wired everything (!) works like a charm.

Im not using any dongel, just router to bridge:

server router bridge wd live

Im using 802.11n and haven’t had any speed issues before.

I googled some info about possible problems with samba and wifi, packet sizes and stuff, haven’t tried it yet though.

Anyone had any simular problems?
