I don't have my Ethernet/wan cables scrambled. In my original post, I stated everything had been working fine for 2 years. Then, all of a sudden, wireless does not work. I have not moved or rearranged any of the wiring on the back of the router.
Also, I have not added any "interference" to my network. The only potential problem I see is when I run Net Stumbler, there is a new network in my neighborhood with a strong signal on the same channel as my network. So, I changed my network channel to 8. There are 3 networks in my area on default channel 11.
Is anyone aware of any firmware bugs/issues? I noticed Richard2 is having pretty much the same problem as me. I wonder if he is my neighbor?!?!
