[RT-N15U] WiFi signal disappear after few hours

[GoogleCodeExporter]

Hello guys,

I bought Asus RT-N15U (upgrade from WL500gx) and install oleg's based firmware 
from this site (RT-N15U-1.9.2.7-rtn-r4051). After that I load factory default 
configuration via admin pages. But now I have problem with WiFi. Sometimes the 
signal completely disappear like today when I come home (about 8 hours from 
router reset).

I attached syslog and system info but in this files isn't nothing what would 
say where could be problem.

Bellow is result from wl status:

$ wl status
SSID: "AP"

        Supported MCS : [ 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 32 ]

Could you tell me where is problem? Thank for your help.

Martin.

Unfortunately, wl driver provided by Broadcom as binary blob without sources.
