I had an older DIR-655 that would frequently lock up - all clients wired and wireless lost internet connection. Sometimes only for a minute, sometimes the only way to bring them back up was to power cycle the router.
I bought a new one a couple of weeks ago: Rev B FW 2.00NA
The wired clients seems to be fine since but the Wireless network just dieappears almost once a day. The SSID is not longer visible and today whan I checked on the router first, before power cycling it, I saw that the entire log was just empty.
I already turned off QoS engine and use WPA only.
Any ideas what's going on?
