Dir-655 hardware A4, Firmware 1.34NA
DAP-1522 hardware B1, firmware 2.02
Both DAP and DIR have the same SSID and password.
Wireless mode n g and b, tried N and G only - no difference.
I had width at 20 and then tried 20/40, no difference
I had channel 1 for 655 and 6 for 1522, just changed 1522 to 11, still getting the restarts.
I do have a 2.4 ghz phone, but I turned it off and put the handset in a metal pot away from the router and no difference.
I turned off Short G1, no difference.
WLAN Partition is off.
I am in the country so no other adapters around - just me. I used InSSIDer and as far as I can tell, everything looks ok.
If I turn off the 1522, then the 655 is happy. With the 1522 on, the 655 will periodically restart wireless, about every 2-5 minutes.
