[Resolved] League Start Lag Makes PoE2 Unplayable

Unfortunately, it is impossible to play on any European server.
My ping to Stockholm is 11 ms, but every 5–10 seconds it jumps to 100–500 ms, which makes the game unplayable.
I tried other servers where my ping is 30–40 ms, but the same problem happens there.
This happens at the start of every season.
Do I really have to wait two weeks again just to play?

Is this my ISP problem?

Using WinMTR, I diagnosed the issue. The problem is on the Wi-Fi side… O_O

If anyone is interested, the problem was that I have a lot of neighboring Wi-Fi networks causing interference.
For 2.4 GHz, I reduced the channel width to 20 MHz (instead of 40) and also set the radio transmit power to maximum (by changing the country to one without restrictions).


This improved Wi-Fi stability by at least 8 times.
