I've noticed I cannot set or change the default empty password for admin. Tried twice and every time I do, the 655 gives me an error message "Nothing has changed, save anyway"? When I save, I momentarily lose connectivity and then it's restored. Then I go back to 192.168.0.1 and try to log in with the changed password and get "Invalid password, please try again"
[edit] After changing the password, it doesn't become effective until you reboot the router. Why is a reboot now necessary for a passwor change?
The other thing I noticed is I no longer connect at 300mbit. Prior to the upgrade from 1.11 to 1.20b7, I was connected at 300mbit/100% quality. I'm using a DWA-652 wireless adapter. The other fun tidbit is I was running the router on Low wireless power and getting that result. But now I've bumped it up to High power and have no better result. It's like something disabled the 40mhz channel. I'm stuck at 130mbit.
[edit] To give more information. I'm in 802.11g/n mode, WPA2/AES encryption, the only wireless device on my network is a DWA-652, auto channel, auto transmission mode, no guest network, and I did verify all 3 of the antennae are properly screwed in.
My 655 is HW A2, FW 1.20b7.
