Hello all! I've been searching all through this forum and I can't seem to find an answer to my problem even though it seems a lot of people have trouble with a slow LAN. My Setup: I have a WebSTAR Cable Modem linked to the WAN port on my Linksys 4-port Cable/DSL Router. Then I have two Windows 2000 Pro machines linked into the router. One machine has a Linksys 10/100 LAN card, and the other a Realtek 10baseT LAN card. I've just formatted both computers so the Network settings are fresh as installed. I only have one TCP/IP installed on both computers with Cleint for Microsoft Networks & File and Printer Sharing for Microsoft Networks enabled. I have turned off all Proxy detection settings and have both computers "Obtaining an IP address automatically" from the Linksys router. (DCHP is enabled) On my setup currently one computer works fine, I am able to connect to the internet with blazing speeds through my Cable Modem. (I did a speed test and was getting 2Mbits per second.) However, on the other computer, which as best I can tell has all of the same settings, I get beyond slow transfers. I am able to ping sites like www.yahoo.com etc. from that computer and get quick ping times (10ms - 20ms) however if I try to dime up http://www.yahoo.com it takes forever to load and rarely gets any of the pictures downloaded before they time out to little red x's. I experience the same slow speeds when I send files across the network. I am however able to send files between computers and can see both computers in network neighborhood. Now that same computer that was so slow with the router is blazing fast if connected directly to the Cable Modem. So my question is, how do I fix the one computer that is so slow? Thanks for any help!

Have you tried placing the lan cable into a different port? Based on what you wrote above the problem likely resets in the port you're connected to.

also might be a idea to replace the Realtek 10baseT LAN card. for a 10/100 nic card.. then atleast ur internal network will run at 100 :)

I also had a similar problem and believe it or not, it was MY CABLE MODEM that had the problem. Myself, (CCNA) and all my co-workers thought it was the router or built in switch but we replaced the modem anyway and it worked great. In this case however, I would try tracert and a webpage to see where it gets held up. If it clings on your router than it might be your router. If it clings before your router it could be your built in switch. Once again, 99% of the time I have a networking problem it is cause by a Layer 1 problem. Try a different cable... If it still doesn't work than try a new NIC, or just swap it with the other.

I have a similar issut. I've just started setting up my D-Link 614+. With the PC to Cable Modem to Internet (i.e. no router) my speed is almost 2Mbps. When I put the router in the middle (PC-Router-Cable Modem-Internet) I'm getting 370Kbps. At first I cloned the MAC address from the PC and it did not work. I reset the router, the cablemodem and tried to "renew all" the IP address - a number of times trying to even get to the net. I changed the WAN MAC address to the same Class C as the cable modem. Still no luck. I then rebooted the PC and it connected to the net but at very slow speeds. I should have rebooted the PC earlier I think. I'm going to go back to the start - clone the MAC address of the PC into the router, reboot everything and test the speed. My question is between the LAN and WAN addressing do they need to be on the same subnet? I'll also run the trace route to see where the delay is.
