Archer AX73 high latency DNS on IPv4
Hi!
After update to the 1.1.0 Build 20211119 rel.46484(5553) version, I've been experiencing some degradation to network stability. After spending some hours of investigation, I narrowed down the issue to name resolution via IPv4 DNS.
Before enabling IPv6 support, ~75% of the time the HTTP(S) requisition would fail during name resolution. I noticed that the problem somehow got worse as the number of connected devices increased (never more than 10 devices, among smartphones and PCs), but I have no strong evidence for it.
After enabling IPv6 support, I noticed that the failures no longer happen, but sometimes websites take some seconds to load, mainly again due to name resolution. So I decided to test the IPv6 support using www.test-ipv6.com and, as a result, sometimes the IPv4 test times out after 15 seconds:
This scenarios happens both via Ethernet and Wireless connections.
I've also reproduced this issue with a single client connected via LAN port, to minimize the possibility of the router somehow being overloaded.
If there is any other information you may need for debugging, please let me know.
Best regards,
Gustavo.
