VPN issues
All devices and home network are good. Signal strength is 2 bars (weak, but functional). Spouse needs to set up VPN to work from home, but even IT from the office could not get VPN to work via T-Mob...
Paso 1
On Windows 10, launch Command Prompt as Administrator
Paso 2
Run this command and get the name of the interface you are connected to. Mine was "Wi-Fi"
netsh interface ipv4 show subinterface
Paso 3:
If MTU is 1500 or more, reduce it to 1400 or lower
netsh interface ipv4 set subinterface "Wi-Fi" mtu=1400 store=persistent
Paso 4:
Verify if MTU is changed
Paso 5:
Reconnect your VPN and try going to pages or applications that had problem earlier. Works like magic. Try lower MTU, maybe 1350 if issues persist.
