P50 ethernet connectivity issues

Greetings,

 

I currently have a P50 running Windows 10 Pro version 1703 OS Build 15063.483 with the latest updates. Same thing with the system, it has the latest updates from Companion. 

 

The issue is in the ethernet port. Sometimes, when I reboot the laptop and log into Windows, the ethernet adapter reads a 10mbps speed and there won't be any connectivity to the LAN even though it is connected to a gigabit switch. After several reboots, the adapter reads 1Gbps and everything works fine. I am wondering if someone else is facing this issue and found a solution.

 

The current adapter driver version is 12.15.24.1 ( Intel Ethernet Connection (2) I219-V )

 

Any help is appreciated.

Thanks

Re: P50 ethernet connectivity issues

I haven't seen this.  Can you try a different patch cable (Cat6 or better)?

Re: P50 ethernet connectivity issues

Lenovo's drivers seem to be way behind at the moment try this driver it may just fix the issue outright.

I updated the drivers thinking it would work but it happened again today. I had to reboot around 5 times in order to have it work again. I also tried restarting the switch, but it made the port totally disconnect. Win 10 read the port as disconnected.

Re: P50 ethernet connectivity issues

After you rebooted the switch did you disable then re-enable the nic in the P50?

Re: P50 ethernet connectivity issues

Yes I did, the adapter switched to 10mbps which is the problem I'm facing in the first place.

Re: P50 ethernet connectivity issues

Was this working fine till you updated to the creators update (1703), what type of router is it, is it a managed switch. Also you never stated whether you tried another patch cord of cat 5e or higher.

Re: P50 ethernet connectivity issues

I've been using only Wi-Fi previously, so I can't be sure when this exactly happened. The switch is unmanaged, and why does the router matter here? I did replace the cable (old was cat5e, newer one is cat6) but it's the same issue.

Re: P50 ethernet connectivity issues

If the port on the router is not negotiating correctly it will fall back to 10 or 100mbps. If it is a home router I would reboot it to let it reinitialize the ports. I'm betting it is a bug in 1703 though.

Re: P50 ethernet connectivity issues

The laptop is directly connected to the Gb switch and so is the router. Why would the router port negotiations with the switch affect the laptop switch link? Am I missing something here?

I'm with you on being a 1703 bug I guess. What OS version are you running on the P50?
