my adapter is RTL8812BU. I tried uninstalling it, i even uninstalled windows and it still doesnt work. when i switch to ac, it connects for 10 seconds, and then proceeds to disconnect. my router supports it, and i dont have problems on my other devices. when i use a/n i get a really unstable ping. when i try switching to a/n/ac device manager crashes and i become unable to close it.I then get DRIVER_STATE_POWER_FAILURE. drivers make the situation even worse. album.
I opened the adapter, and it turns out that you were correct: the antennas arent connected properly.turns out my laptop supports 5ghz, sorry about that. However I bought a new adapter (a6150 from netgear), but i now get "cant connect to this network". 2.4ghz connects perfectly ( if we ignore the 200 ms ping to 192.168.1.1). Should i open a new thread, or is it part of the same problem?
