I have a problem with my Dir-451.
Even when wifi is disabled, the unit is broadcasting a strong signal on channel 1 without an SSID.
The Wifi indicator on the unit is off, but Netstumbler shows a strong transmission from the device.
This issue is causing problems in my setup as it interferes with other client's ability to connect to other access points.
I have tried Firmare 1.2 beta 25, 1.2 beta 26, and 1.21. The problem is present in all firmware versions.
I hope you can provide a solution.
Thanks
