Then try restarting the workstation. And execute a wireshark or tcpdump on it trying to capture all traffic (IP, ARP …)
Do you see something interesting ?
I appreciate your help, but I’m not going to those lengths.
I’ve pretty much lost patience with Teltonika now. At the time of writing, the router has almost frozen. I’m getting download speeds of 650kbps, so I’m going to switch back to my 4G service.
Unless the UK supplier comes up with a solution tomorrow, I think I may ask to return the router for a refund.
PS: Just switched back to 4G router and am getting 15Mbps.
