Hi all,

I have strange problem on some mikrotik Ap (mikrotik with atheros cards). I am using on my network AP with chipset realtek 8181 as client.
The problem is that in registration table:
Tx = 1Mbps :?:
Rx = 11Mbps
Signal strength is -64dBm

Generaly Tx is only 1Mbps :/ It not depend on version of Mikrotik (2.8.x, 2.9.x) I tried 4 diferent atheros cards also...

Any other ap client with chipset different then realtek works fine...

Some mikrotiks with relatek as ap client works fine for months, but some days (without any configuration change or hardware) stop work :(.

Thanks in advance for any suggestion
