I am having a weird issue where, every five minutes (basically to the second) I lose the ability to ping my router, as well as google dns (8.8.8.8), for about 20-30 seconds. This issue does not coincide with my wifi changing channels, nor changes in the RSSI or Noise. It happens at the same exact time for multiple laptops, so I know it’s not a single device. I have a AT&T BGW 320-500 router, which does not have uPNP.
My router logs are filled with “Generic Discards” (TCP), where the source IP addresses show up on AbuseIPDB as malicious IPs. As well as the occasional “Other DoS attack”. But these are happening basically continuously, and don’t coincide with all the wifi outages.
What could be going on? What should I check?
