I have a laptop running Vista Home Premium. I bought a D-Link wireless N card. Then I bought a Trendnet wireless router. Aside from a few beginner issues it all worked fine for a while. In my status page of my connection I would read 300Mbps. Ocassionally it would drop down to 54Mbps. I couldn't figure out why and couldn't tell you when it would do it because I only would notice when I was suspicious of slow file transfers. Sure enough I'd check and it would've dropped to 54Mbps. I called D-Link support and Trendnet support. D-Link seems to think it's Trendnets (router) issue. Trendnet is supposed to call back with a escalated called to a technician (no call yet).

But here's the kicker, I cannot connect at all at 300Mbps anymore ony 54Mbps. The only way I am able to is by connecting without any Security Mode enabled (within the router set-up page). I have tried all the others available security modes and still the same thing. And the other thing that was always a concern but never became an issue until maybe now. If I hold my mouse over my connection in the Wireless connections page it always says "radio type" 802.11g (as apposed to 802.11n) But at that time I was able to connect at the full "N" speed on 300Mbps so I never real took it seriously figure it was a Vista glitch.

Any advice for a networking newbie?

Be gentle!
