Bf1 high ping since 12/6/2017

@taquete Have you already tried this if not please give this a try.....

1- turn off PC

2- Unplug power from modem and router if you have both

3- Leave it unplugged 10 min no less

4- If you have both modem and router then ... After 10 min plug modem back in let it fully boot up. Then plug in router and let it fully boot up.

5- Then turn on PC and see if it helps your ping at all.

If this fails to fix it then please try steps below.....

Regular internet usage causes your computer to automatically cache IP addresses and other domain name system results. Clearing (or "flushing") this cache will refresh the data, getting rid of outdated data that may be causing connection issues.

Note: These steps should be completed using an admin account. You will be typing prompts into the CMD console, so it is very important that you enter the commands exactly as shown.
Also, the following steps are specifically for PC players.

Windows 8
Navigate to the desktop.
Hold down the Windows key and press R. (This will open the Run dialogue.)
Type cmd and press Enter. (This will open a command prompt.)
Type ipconfig /flushdns and press Enter.
Type ipconfig /registerdns and press Enter
Type ipconfig /release and press Enter.
Type ipconfig /renew and press Enter.
Type netsh winsock reset and press Enter.
Reboot the computer.

Windows 7
Hold down the Windows key and press R. (This will open the Run dialogue.)
Type cmd and press Enter. (This will open a command prompt.)
Type ipconfig /flushdns and press Enter.
Type ipconfig /registerdns and press Enter.
Type ipconfig /release and press Enter.
Type ipconfig /renew and press Enter.
Type netsh winsock reset and press Enter.
Reboot the computer.

Windows Vista
Hold down the Windows key and press R. (This will open the Run dialogue.)
Type cmd and press Enter. (This will open a command prompt.)
Type ipconfig /flushdns and press Enter.
Type ipconfig /registerdns and press Enter
Type ipconfig /release and press Enter.
Type ipconfig /renew and press Enter.
Type netsh winsock reset and press Enter.
Reboot the computer.

Setting an alternate DNS:
While a DNS refresh might solve your connection problems, the DNS itself could potentially not be working as intended, and connection issues will continue no matter how many times you flush your DNS cache.

You can check if you DNS is failing by trying to switch to a public DNS like Google DNS by following the steps on how to use Google Public DNS straight from developers.google.com.
https://developers.google.com/speed/public-dns/docs/using

Google DNS might actually be slower than your normal DNS, but is useful to test and see if your connection problems are coming from your local DNS.

@2042isNotBF thank you for the help. I already did all that, flushed dns caches, tried other dns, I even unplugged the modem and the router the whole night, but to no avail. The problem still persists.

I've been reading that it may be a bufferbloat issue, I'm not sure tho. I'll try the fixes i found over the internet and get back to post the results.
