100mbps on ethernet port

#1 Post by ibrahim52 » Sun Jan 05, 2020 1:55 pm

This is my very post and I never knew about such amazing spot for thinkpad fans. I actually tried looking for similar topic before posting but posting it anyway because I have tried almost every possible solution available on internet.

WiFi is fine, works over 300mbps but ethernet (Intel(R) Ethernet Connection (3) I218-LM) despite of resetting windows 10, updating bios, updating each and every driver, removing all vpn tap drivers. Nothing helped, whenever I connect to any gigabit based port, I get only 100mbps, fixed 100 always. If there is any way to fix this. Thank you.

Welcome to the forum!

Which ThinkPad model are we discussing here to begin with ?

Have you tried it on another router port?
Have you tried it at another location?
Is yours a proper Cat5e or Cat6 cable?
Have you tried the latest Intel drivers?
Are you running Windows (which version) or Linux?

It's the same issue here. I have 5th gen corei7 and Ethernet gives max 100mbps. Tried plenty of cables and gigabit routers. I am not sure if it's after bios update last year August.

Could it be a slightly damaged port?

Not in my case, attaching pictures of my ethernet port I took with flashlight on.
