I had to change from Fiber to LTE. Now my SSH keeps timing out.
I can enable keepalive under Settings->Configuration->SSH->Keepalive, however this always sets it at 60s. 10s seems to work better for me.
I can set the keep alive in the PuTTY config menu by Ctrl+Right Clicking on the prompt and going to Change Terminal Settings...->Connection.
I unfortunately have to do this every time I start MobaXterm.
The default MobaXterm.ini file unfortunately does not have the option to change the default keepalive timeout from 60 to something else.
