My goal was to enable my work notebook computer to ACCESS high-speed Internet connectivity from home as opposed to very slow dial-up connectivity. I purchased a D-Link Ethernet Broadband Router (EBR-2310) with four 10/100 Ethernet ports.

I have high-speed broadband Internet from Cox Communications. My desktop will be connected all day (actually 24/7) to the router as will the Motorola Surfboard 5220 modem. The work notebook computer will be connected to the router maybe 3 or 4 times a day maximum to primarily to check work e-mail and to submit reports, after which it will be disconnected from the router. In other words, the work notebook will have limited connectivity on the router.

Under those parameters, did I short-change performance for my desktop by not obtaining a Gigabit router even though for most of the time it will be the only computer connected to the router? Everything seems to be working well with the 10/100, including upload and download speed TESTS via Speakeasy speed testing.

Thanks!In a WAY, you answered your own question. You've done the speed tests and the results were GOOD. That's very good proof that you'll be fine with that router. Having two computers online at the same time will not be an issue at all unless you're continually downloading huge files on both computers. For web browsing, email, etc., you won't notice the difference when both computers are using the Internet.
