Yes mine is having trouble seeing my router(dir-655) as well. It sees other routers though. Also the windows laptop next to it has no problem seeing it and connects right away. Does it matter that my router is not broadcasting its name?

I did add the router network to the Imac so its there. Its just not seeing it. Also added the Imac to router's list of allowed computers.

I can sometimes get it to work if I do the "join a network" option and manually type it in. Although if I already have it in there, I dont think I should have to do that right?

When I get home from work I will go through changing the channel and see what that does.
 
I have a brand new 3.06ghz flagship iMac and it was doing the same exact thing as described here. I tried rolling back the firmware on my AEBS and thought it fixed the problem and after two days, same thing again.

I changed channel to channel 11 and now surfing the net is bullet fast. Almost every page loads instant!!!! it is like I have a dedicated line or something. No more drop and blazing speed for anything online. Me likey!!!!

Odd why changing a channel would do so much, but it DOES. Mine was set to the default Automatic channel selection.

Just wanted to say thx for this thread. I had started a similar one a while back but never got a good answer. It's great that this ended up being so easy to fix.
