I have the exact same router (TEW-633GR with firmware 1.0.4.3) -- also using WPA2, etc... This problem happens all of the time with all of my Android devices. I have a Motorola Droid, my wife has the Motorola Droid 2, and we both each have the new NookColor from Barnes & Noble. All four of those devices have the connection problem. They connect, and the Nook reports the status as, "Connected, but no internet". I can see the devices on the network from the router, and they all have active DHCP leases, but the route to the internet seems to get lost somehow.
I looked at the TrendNet log and found this:
[INFO] Fri Sep 25 09:20:49 2009 Wireless system with MAC address 58671A030AAE associated

The date is wrong in the log file (I fixed that on the router and got the same results with the correct date).
I am now trying to figure out why all of the Droid devices connect and then send a "Deauthentication" -- or, at least, why the Trendnet believes they send a "Deauthentication"....
Does anyone have any ideas?
Also worth noting: I have an old linksys wireless router that I put back into operation. I created a secondary wireless network with WPA2 on it with a route to the internet. This connection works fine. The problem seems to be isolated to the TrendNet device... I am going to open an issue with them, as well as hope soemone here has any ideas.
Thanks!
