Wired ethernet speed slow
I am having the same problem. It seems to have begun 2 weeks ago in my case when Windows11upgraded to 22H2. It is only affected wired ports. WiFi unaffected. It is affecting every PC upgraded to 22H...
Had a network tech friend bring his Asus GT AX-11000 to test in my home and we experienced the ethernet throttling the same even with the Asus. He then turned off IPV6 on my NICs properties, rebooted, retested and problem is resolved. I now have full ~920Mbps download on a 1GbE NIC as expected from using either the Asus or the RBK852 simply using IPV4. Circumvention is to turn of IPV6 in NIC properties.
Apparently Microsoft released an update to 22H2 today, for Windows 10 and Windows 11.
Hi Crimpon,
Just finished installing patches and am happy to report that installation on KB5018496 and KB5018341 has resolved this issue in Windows 11 22H2.
- MS Update. I thought it was fixed but the problem resurfaced in about five minutes after installation so I’m going to get another non-Netgear router and give this another test and report back. ☹️

Interesting. Something with MS and IPv6 mis-handling?
- This issue has been fixed by Microsoft today in —KB5022913 (OS Build 22621.1344) for Windows 22H2.
