I have been having issues with connecting to the wifi with my adapter (TL-WN781ND). I didnt have this problem before since I used to have a wired LAN connection. Whenever i try to connect to the wifi, it either fails to connect, which the windows network diagnostic does not specify why, sometimes it gets a dhcp error or the sorts. When it DOES manage to connect by some miracle, it either disconnects again, or the wifi gives no internet after a small period of time, even though my phone is connected just fine to the internet. I have tried reinstalling the driver to no result. Nothing seems to be working and I am confused as to what to do. Using a wired connection seems unlikely at the moment. I bought ANOTHER adapter which was a USB adapter (I think it was TL-WN725N) and it was the same, which believes me to think the problem might be with my pc, but that makes no sense as far as I know. I'll appreciate any help I can get. Thank you.
