Excessive ping/lag

[ghe]

In the past week i have excessive lag no matter what I do:
- I checked internet speed test I have over 150 mbps and ping 10 ms.
- I join the lobby, have a ping of between 20 and 40 ms
- as soon as the game starts it ramps up to around 80 - 100 ms
- after a while it goes to around 200 ms. In a big team fight I get over 500 ms. Can't play at all.
- I reinstalled battlenet and w3. Same issue
- I reinstalled windows, battlenet and W3. Same issue
- I restarted the router several times. Same issue.
- I even tried to play on 4G connection (by sharing my phone's data connection). I still have ove 120 ms ping, unplayable.
- I am connected to WIFI an always played like that for the past 2.5 years since I moved to a new house/country and I always had under 30ms ping which was perfect.

Anyone has any ideas of what else I can try to find where the issue is?
Thanks in advance.

Same here.

played 2 games last night and had great ping (under 20 ms).
So I assume it was either the server or something wrong with my internet.

We will add bot reboots once a week or something, seems to appear randomly after a long uptime or smh.
