XB8 Packet loss every 3 mins on AX band

Hello,

I believe there is a firmware bug on XB8 side which is causing packet loss every 3 minutes or so causing lag in gaming. This only happens on Wi-Fi 6 (802.11ax) protocol. FWIW, I have validated this with forcing to pick 802.11ac band and it works fine for hours. I first noticed this roughly 9/11/2024.

I have since then tried everything updating windows drivers (bios, chips, nic, etct), played with adapter settings (low roaming, throughput booster, etc), resetting windows entirely.

Last night I did a hard reset on the router and it worked fine for hours on AX band. I believe it updated firmware over night and we are back to the issue.

This might be due to bad firmware Prod_23.2_231009 & Prod_23.2_231009 and i also found this.

I would also like to add that I get Large Segment offload (intel warning 6062), "Connection telemetry fields and analysis usage" (7021), and "roam complete" (7003) every 3ish minutes (sometimes more or less) from my nic. These 3 info/warnings do not happen when I am on AC band or the router is hard resetted.

I performed another hard reset around 12am this morning. Its 2:30 now and few 6062 errors but nothing major.

I was able to play games without many lags, may be 1 or 2 with correlated warnings.

Around 3:00am i decided to manually reboot the router via "RESET" button and viola lags are back. I believe firmware upgrades are done on resets.

I also have a powershell script that pings every second to google's dns and warning times co-relate with ping timeouts too.

`ping.exe -t 8.8.8.8 | ForEach{"{0} - {1}" -f (Get-Date),$_}`
