problem in freq.

Dears

i have point to point (MT RB 433AH with mini pci R52)

in the scan show to me 3 freq. to the same second point (-86 , -67, - 85)

im choose the best freq. (-67) and connected to gather

but after 6 or 7 hours the freq. change auto to the bad signal (-86)

are there any idea to this problem?

thanx

Use different SSID for each AP else 20MHz channel wide is more advisable.

It is not esay to debug,
but you can use the connect list function (under interface wireless) to select the right mac address wlan that you want connect
