Question PC WiFi connection disrupted by devices connecting

[Eifersucht]

I recently built a new computer and was able to connect it to the WiFi successfully. However, the new PC has an issue where the network connection gets disrupted when a new device connects to the WiFi. I have checked IP addresses and it doesn't look like any devices on the network share the same IP address. The disruption seems to only occur on the new PC. After resetting the router, the issue has not been resolved but it does seem as though different devices connecting now cause the disruption. Any suggestions as to how to resolve this issue?
