Server list long scanning

When I entering Multiplayer after game loads, servers status doesn't show up around 37 seconds. Not only not showing up, but not joining ("Timed out"). After, it works normally.

P.S: Disabling/removing excess ethernet adapters/devices not helped - same ~37 seconds.

P.S.S: I am used smartphone with Wi-Fi as USB modem, because Wi-Fi adapter has an unstable connection after some time of using (8 - 8 - 9 - 1052 - 2042 - timed out - 10 - 12 ms ping)... but, now, I am using this Wi-Fi adapter AGAIN... AND server list scans FAST!
