WRT54G doesn't play well with gigabit ethernet adapter

Before I got this wireless g router (approx 5 months ago) I had the regular linksys 4 port cable/dsl router. I had everything at my house connected to that router. I had one Win2k Pro machine, one Win2k Advanced Server, one WinXP Pro machine, and one WinXP Pro laptop. Around Christmas time I purchased my linksys wireless g router because I have a built in wireless g adapter in my laptop. Everything still worked fine. My WinXP Pro workstation even connected (hard wired) without problems. I was experiencing some transfer speed issues with my laptop so I decided I would "plug-in" again and see if that had better results than the wireless. Well I didn't get a connection at all. My laptop and router both wouldn't even show that a cable was connected. This drove me crazy for weeks until I finally decided to forget about it. Not really thinking of it at the time....now I realize that my laptop also has an onboard gigabit adapter. Just last week I completed building my new workstation which also has an onboard gigabit adapter and guess what.....no connection on my router. It's the exact same thing. Network properties has the big red X on my connection and says the cable is unplugged. Also there is no light for that port on my router. Finally after troubleshooting forever I found that if I manually set my adapter speed to 10Mbps Full Duplex I got a connection. I got the same results on my laptop as well. So now I have two machines with gigabit adapters that will only communicate with my WRT54G router at a speed of 10Mbps. Now I know I won't achieve 1000Mbps but I should be able to communicate at 100Mbps with no problems. And when I say they won't communicate...that means they won't even ping the router until I set the adapters to 10Mbps.

I contacted Linksys about this issue. Aparently it was a known issue but the in"duh"vidual that I spoke with wouldn't give me any details. The only solution that Linksys had to offer was to manually set my adapters to 10Mbps because "some routers have syncronization issues with some network adapters".

Any ideas......anyone.....hello.....Bueller???

Adapter driver, adapter driver, adapter driver.

This one I think Linksys is blameless for. There is clearly an autonegotiation failure. And I honestly do not think it is the fault of the poor WRT54G (excellent choice by the way).

Talk to the gigabyte NIC tech folks. I am not suggesting that the autonegotiation logic of the switch portion of the Linksys is faultless, but when you get "no lights" with the NIC at default settings, I tend to think there is something non-standard about the voltage or autonegotiation logic on the NIC rather than the switch or router.

Well, I got this problem taken care of on my workstation finally. I went to Gigabyte's web and grabbed a different driver for my NIC and now that one works fine. Unfortunately, my laptop still can only connect via wireless but I guess thats not really a problem after all.

If there is an adapter "bonding" feature, disable it.
