Networking issues on specific sites/apps

Hey guys,
Today I woke up to my arch install having network issues on some specific sites/desktop applications.

In particular cli apps like pacman, desktop apps like megasync and sites like google drive only download/upload at a few kilobytes a second, but cli apps like speedtest-cli and sites like speedtest.net indicate my normal download/upload speed of 100/10 Mbps.

It is the first time this has happened in arch (usually the problem is that I have no internet connection at all) and I have no clue where to start debugging. I do not remember if an update caused this cause I only put my desktop to sleep(after a reboot I would be able to percieve the problem), but I have tried:
- restarting,
- ranking pacman mirrors (which wouldnt help with megasync/google drive),
- restarting networkmanager,
- fixes like: sysctl net.ipv4.tcp_ecn=0,
- reinstalling network packages but as the download speed is horrendous it would take an hour to do, so I aborted,

and I get no results. Pretty frustrating, I dont want to end up to have to re download as this installation is only a couple months old. Anyway, I would appreciate your guys' help and thnx for taking the time,

George.

Re: Networking issues on specific sites/apps

Do you have a mobile phone with a reasonable download speed (4G/LTE) available?

Exclude the network hardware between PC and router: Connect your phone via USB and enable WiFi and "USB tethering". Your arch will recognize your phone as a second ethernet connection. Switch off your normal ethernet and retry your transfers.

Exclude router and provider too: Switch to mobile data while using the USB tethering setup. Try again.

Hi mate,
Thanks for taking the time o7. I've used USB tethering in the past (thankfully, those udev rules are so annoying to configure xD ) because of some  network outages with my ISP, so I set it up and everything works perfectly both with WIFI and with data (different provider). So in this case, what would then be the culprit if it is not the router, nor the provider? Probably network hardware?

Well nevermind there is no culprit xD. After unplugging and re-plugging the network card, restarting the PC, updating through USB tethering and restarting again, it fixed itself. Guess 1 restart wasn't enough, but 3 were. Oh well, thanks for taking the time.
