I have a Dlink DIR-655 router. On paper the router sounds great. However, it has a nasty access point problem. The access point seems to continually go offline. The only way you can get it to work when this happens, is to either reboot it or physically turn it off and on.
Like most devices, Dlink is no longer providing Firmware updates for this. Weird because it still a big seller at the stores. The last Firmware version was 2.00, which was dated May 12, 2010. So although this seems to be a common problem, Dlink is no longer going to fix it for you.
I finally resolved it. There seems to be a problem in the QOS engine. The WAN Traffic shaping section seems to cause the problem. Specifically the problem seems to be around the automatic uplink Speed. When set to automatic the WIFI seem to go offline constantly and the router seems to restart frequently. I resolved it by turning the “enable Traffic Shaping setting off”.
To Fix it do the following:
- Select Advanced from the top menu.
- Select QOS Engine
- Deselect Enable Traffic Shaping
- Save Settings.
