Archer AX55 EasyMesh devices spamming unnecessary DHCP requests and DNS queries
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
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.
