I Noticed a massive delay when i try to open any site, even the router page. I tried to debug "literally" the issue as following:

  1. I pinged my router via $ ping 192.168.1.1 and their was too many peaks and valleys with loss of 10%!.
  2. I opened windows to ping the router but it was steady and their was never any spikes or packet loss.
  3. I opened linux in rescue mode and pinged the router again and surprisingly the result was same as windows!
  4. I tried to turn-off wifi power management via the following $ iwconfig and i obtained the wifi card name then I turned it off via $ sudo iwconfig wlp0s20f3 power off. Nothing nearly changed.
  5. I got confused and I though that my laptop is being spoofed or hijacked when it connects to internet so I watched the internet usage using gnome-system-monitor but it revealed no internet traffic.
  6. I turned off my VPN program (expressvpn) via $ systemctl mask expressvpn.service but the issue remained.
  7. What I noticed is that, when I open google-chrome, the ping issue appears and when I entirely kill google-chrome, the ping returns back to normal just like windows or linux-rescue or even my phone!
  8. Tried to check chrome task manager and there was nothing downloading/uploading.
  9. Closed all tabs entirely so that chrome is opened on home and the issue remained.
  10. tried reinstalling google chrome but to no avail.

I am 100% sure that there is a correlation between both and 99% sure that chrome is the cause for the massive packet loss and very high latency (9000 ms on average compared to 4 ms when it is closed).

No matter what time I give google, but the issue remains unresolved as if it is itself is making very high traffic.

My laptop is Lenovo Y530 with wifi card Network controller: Intel Corporation Wireless-AC 9560 [Jefferson Peak] (rev 10). I updated the BIOS from 2 to 5 months ago (cannot recall specifically) and i found in $ dmesg this error BIOS contains WGDS but no WRDS which is addressed in this link.

There was two solutions to such problem:

  1. Contact Intel regarding your product and they will solve it for you.
  2. The issue was due to a very similar WiFi Bandwidth nearby and the solution was to simply restart the router as the issue turned out to be from it despite that the issue was with a single device only.
