WiFi router issue

Spending quite some time in the morning trying to get the internet working in the Condo. The TrendNet TWE652BRP WiFi router has been misbehaving for quite some time. The main symptom is dropping wireless connections quite frequently (as bad as every 5 minutes) while the signal showing on the devices was still strong when it happened and the wired connections are unaffected. Some times, it also crushed, but this was not often. For most of the devices, it will automatically reconnect after 1-2 minutes. However, this is very annoying as my HD media player is wireless. Every time the connection was dropped, it will either just stop playing whatever online content I'm watching or drop the connection to my NAS drive where most of the HD content are saved.

I've tried updated it to the latest firmware, and tried to change various settings. Some times it gets better and most times it's not affected. I'm not even sure whether it's the setting change or just the number of time it's rebooted that helped a little. To just temporarily curtail the problem, I had an old CompUSA OEM 802.11g router connected for most of the devices that do not need access to the NAS drive.

Originally, the CompUSA router was connected to the TrendNet one through one of its LAN ports, while the TrendNet router was connected to the DSL modem. I had suspected that the load of the TrendNET router may be a contributing factor so it was changed to not running the PPPoE but just taking the connection from the modem. However, it crushed last night and I decided to switch the hierarchy of the two routers: the CompUSA connects to the modem while the TrendNET follows. This seemed to be an easy change but somehow the CompUSA router refused to run acquire neither an IP from the modem nor will a fixed IP run (the TrendNet worked fine under either, only to crush).

After an hour of changing back and forth, I gave up. I just need to get a new router. In the mean time, I just hanging there try to score a better deal on Boxing day (the Canadian Black Friday). My ideal choice would be a simultaneous dual band Wireless ABGN router with 5 Gigabit LAN ports (plus a WAN port).
