I have noticed when I connect to a client that has multiple nics, the connection performs quite poorly. I have checked the client's default gateway, and all looks ok. Has anyone else observed this behavior? Any suggestions on how to improve the performance?
I connect to servers with multiple NICs and I don't have any problems.
Sometimes I connect to laptops that are plugged into the LAN and connected to WiFi. This can cause network problems (not just for TeamViewer) if Windows doesn't have a preferred connection. In this case I usually have the user unplug the NIC and just use the WiFi.
If it's an option, I recommend unplugging all but one NIC just for troubleshooting.
Chiron, thanks for your insights / info.
I would agree if there are issues and we could unplug a nic, that would likely fix the issue. When I have this issue, I am connecting to a server or unattended system for system maintenance. Unplugging a nic is not an option. We have several systems that perform data collection on one network and then present the results and data to another.
