Archer AX55 EasyMesh devices spamming unnecessary DHCP requests and DNS queries
I've noticed that my AX55 EasyMesh devices are constantly issuing unnecessary DHCP renewal requests and DNS queries.
Main Access Point:
- DHCP renewal every 110s
- DNS query every 50s
Satellite:
- DHCP renewal every 50s
- DNS query every 10s
For the DNS queries they cycle through the following hostnames in random order: "wikipedia,org", "amazon,com", "reddit,com", "bing,com", "linkedin,com", "live,com", "netflix,com", "google,com", "yahoo,com", "ebay,com", "tp-link,com", "a,root-servers,net", and possibly more. (Of course with dots not commas, but the form doesn't allow that.)
Additional notes:
- Both devices are running the latest beta firmware. Behavior was very similar with the beta before that.
- I've recently "downgraded" the main router to AP mode, but I've previously noticed similar behavior in router mode.
- I now have a separate router (not TP-Link) that acts both as DHCP and DNS server.
- DHCP server on the main access point is disabled, but the behavior was the same when it was my main router.
- The DHCP server on my separate router issues leases with 2h duration.
Is there an explanation for this behavior? And where can I disable it?
Especially the DNS queries: Network equipment has no business making random DNS queries for completely unrelated hostnames. I understand that occasional queries are necessary for firmware update checks or similar, but this is definitely something else.
