I'm trying to find out if the people with modems crashing and or those with launcher patching issues are using USB for their network connection between the PC and their modem/router out to the internet.
If you are using USB and having problems, the first thing to do is to not use USB but to use a network cable (RJ45 aka "Cat5") between your computer and the modem/router. Most if not all modern computers have a built in NIC on the motherboard.
Also, if you HAVE to use USB (ugh), make sure you aren't using a USB hub in between your modem and PC and have current drivers for that USB networking adapter. But please please please don't use USB.
At the moment my launcher doesn't even begin to process the patch before the server connection crashes. I'm using a wireless network, and the only firewall I'm using is the basic Windows Defender firewall that came with my computer. Any idea why it isn't working?
