Hi,

I have issue with XR5 cards and RB433AH working in AP mode.The Routerbard's (3 of them) are placed in very well constructed plastic box, with needed air circulation. Strangely all the clients linked to AP fall down in 6 Mb/s connectivity, some 12, but the ping was very bad, several timeouts, one bad response, again timeouts....
Immediately I changed cables, connectors, sector antenna, even all of them they have been very good isolated (it was raining), but the same situation.
I change the wireless card (XR5), everything working fine.
The same case ofter two weeks, in another Routerboard, same box, I changed wireless cards, everything fine.
Please if somebody had such experience let respond.
