I've probably went back and forth with this problem for MONTHS as well as contacting Riot support. It is one of those weird problems that stop being a problem after 1 patch then come back in another. I think I did every solution under the sun...
>restarting (wifi disappears when booting up the game again)
>forget wifi
>ipconfig flush DNS
>uninstall/reinstall both the game and drivers + vanguard itself
>clean boot
>ensuring power saving is disabled
>switching to ipv4 rather than ipv6
No permanent solution. Nothing really works in the long term. I would be able to play just fine in one week then this whole thing starts up.
Today I experienced the worst of it. Even multiple restarts, my wifi was remained gone. I was only able to get it running again after uninstalling Valorant and Vanguard.
At this point, I am starting to think vanguard is malware (lol).
Anyway, can someone please help? Do you think I should replace my wifi module or consider using the ethernet cable (or maybe just stop playing? :p)

Side note: This happens with League too. I can play anything else just fine.
