Where there are dozens of routers, as in an apartment building, they share the same channel and have to wait for a chance to transmit.
Why Dozens of routers use the same 2.4 GHz channel → Effect Before transmitting, a device waits until other devices finish and the channel clears → On screen In the evening, when people get home, jitter (variation in packet arrival times) rises and the game stutters

Tell players to use 5 GHz or 6 GHz, a less crowded channel, or a wired connection.

Where to look
Check the channels and signal strength of nearby Wi-Fi networks with netsh wlan show networks mode=bssid, and compare ping to the router in the evening and during the day
Confirmed if
Many nearby routers show up on the same 2.4 GHz channel, and jitter to the router grows only in the evening. Moving to 5 GHz or 6 GHz or to a less crowded channel reduces it
Ruled out if
Spikes regardless of time of day: “Wi-Fi interference and weak signal.” Fine up to the router but bad beyond it in the evening: “Peak-hour congestion at peering links”

Recommended settings for Wi-Fi routers and access pointsApple Other routers and devices on the same channel are sources of interference; 20 MHz channel width is recommended on 2.4 GHz; interference is less of a concern on 5 GHz and 6 GHz
