I have a DWA-192 that I got earlier this year. I've been trying to use it to connect to my router, which is a Netgear N150 WNR v3 router, on a Surfboard SB6121 modem. The router/modem setup is totally fine and other devices connect fine.
However, it mostly refuses to connect - I can see the network, and type in the password, but then it either says it can't connect or it barely connects. If it connects, it gets horrible reception - 80-100 ms ping, and often having spikes in connectivity. I have a Linksys USB adapter that gets significantly better performance than this.
I've tried installing multiple drivers, including the ones from the box and the two most recent, but all have failed to improve things. I have Windows 10 home, and it did work decently well when I was at my old place, with a different router.
Is there any fix to this? Are there tests I can run to try and figure things out?
