I bought this adapter yesterday and tried it but it either disconnected the whole time or after a couple of minutes and failed connection attempts it connected to my router constantly, with 30 ms. The problem is: I ran a speedtest and it needed 10-15 mins to actually measure my connection speed. It came out my ping is 30 ms, download 0.09 Mbit/s, upload 0.58 Mbit/s. So it is working but I cannot do anything with this speed!? I tried reinstalling, installing with the cd, downloading the driver and reistalling, restarting the PC. Nothing changed anything. If I connect with cable I get good numbers, around 5 MB/s (download). I need help I don’t know what I can try. Not even manual IP setting works. Ipconfig shows no problems either, device info says the adapter works as well.
