I used and sometimes use Opera VPN, once before used SoftEther VPN client, My anti-virus always turned off.
When I has an issues with connection to other games I always used Fiddler 4 and he fixed any problems, but still can’t fix anything here.
I got Avast Antivirus but turned it off long ago.
Adapter in my laptop is Dell Wireless 1705 802.11b/g/n/ (2.4.GHZ)
I don’t have a protocol file in the folder, only Hosts.
