I have a cable broadband connection that runs through a D-Link router. On either computer I have, I can go to dslreports.com and run a speed test and get about 4000/800 kilobits download/upload respectively. I recently wanted to try wireless networking, so I bought a D-link wireless card and a D-link wireless router, both 802.11b. Now when I run a speed test through the wireless, I get about 1700/800 download/upload. Even when I plug the other computer into the router with an ethernet cord, I still get the same results. Is wireless internet supposed to be slower than the bandwidth you could normally get from your ISP? I would think that the computer plugged into the router with an ethernet cord should get something around 4000/800 that I was getting with just a normal router.
