Re: Trouble with connection to work VPN
I am using T-Mobile 5G home internet. Everything works great, but all of the sudden when I connect my work laptop to the VPN, nothing over the VPN works. This was working fine for a year. Not sure if there was a firmware upgrade something that caused this. After a ton of searching, I found the issue for me. It was the MTU setting on my laptop. This is very easy to fix. It was as simple from changing a setting from 1400 to 1374. That worked. Google hot to check your MTU size. It is with the "NETSH" command. Do some ping tests forcing a MTU size until you find the best one. Make the change. Very basic overview…. 1. Checking and changing the MTU size Open a command prompt as admin Check the MTU size as it is set now. Netsh interface ipv4 show interfaces Before we change the MTU, we need to find the optimum size by using this command Ping 8.8.8.8 -f -l 1400 It is showing as fragmented. We want to find the highest number where we do not get that. So keep trying numbers, lower and lower until one comes back normal. For me, it was 1346. That's our base number. Fore technical reasons having to do with headers, etc, we need to add 28 to that number. My number would be 1374. 3. Change the mtu (CMD as admin) Netsh interface ipv4 set subinterface "Ethernet 4" mtu=1374 store=persistent (Ethernet 4 is the name of my interface, yourswill probably be different, like "Wifi" ) Now check your change. Netsh interface ipv4 show interfaces You should now see the new MTU11Visto2likes0Comentarios
