How sad, I used to tinker with my 655 all the time... unplug, plug back in... tweak settings, change wireless adapters, change adapter settings, on and on... then I bit the bullet and upgraded to 1.34NA after hearing people were having success... at that point one of my wnda3100 adapters would drop every so often; would not allow large file transfers without disconnecting... it was even worse than before... so, I got a refurb wndr3300 and it does everything faster, better and with no stability problems at all. Better range, better voip, no drops, transfered 56GB to my backup server, no problems...
The things I miss are Guest Mode and of course 2.4GHz N 300 is not available, only 5GHz. the DIR-655 is a bit more configurable; QOS is more flexible, but who cares, the 655 just doesn't work as good, and is more expensive.
Now, if I could figure out a way to connect a second router to my wndr3300 to emulate Guest Mode with 2.4GHz G and N wireless only, with a separate SSID that could access the internet but keep Guest machines from gaining access to the shared files in my computers connected to the wndr3300 I'd be in HOG HEAVEN.
