I've Huawei DG8045 VDSL router, when I'm connected over its wifi my VPN gets disconnected after few minutes but when I'm connected using lan cable I can use my VPN connection normally. I tried to disable the router firewall but the problem still exist. I've tried another router (old ADSL2 BILLION router) and I can connect to VPN normally whether using wifi or lan cable. Any ideas what can I do?

  • Missed to say that when using WiFi internet connection is good, speed is over 20 Mbps (using speedtest.net) – Ebrahim Sadeck May 1 '20 at 16:10
  • Internet speeds don't take anything like packet loss into account, so you'll need to do additional tests to check the quality of the connection. – user May 1 '20 at 16:34
  • I think ping and jitter numbers are also good, with 0 % packet loss – Ebrahim Sadeck May 1 '20 at 18:41
  • Ping is 8 ms and jitter is 4 ms – Ebrahim Sadeck May 1 '20 at 18:43

Fixing channel to 11 instead of Auto in my router WLAN settings solved my issue. Now I can connect to VPN successfully over WiFi.


Don't put your router on Auto WLAN setting try to fix channel on 11, or another. This will solve my problem in just few minutes. Restart your router than try it :)

  • Thanks, this worked with me yesterday. However, today my VPN connection keeps going down again .. I changed channel back to auto then VPN connected for a while.. I think this is still not the root cause of the issue. – Ebrahim Sadeck May 3 '20 at 15:00
