I use a Lenovo Thinkpad E495.
When WiFi roaming,
6062-Lso was triggered
appears in Event Viewer.
22:05:01.2198709: 7021 - Connection telemetry fields and analysis usage
22:05:01.2198709: 7003 - Roam Complete
22:05:29.8405925: 6062 - Lso was triggered
Non-roaming (about once a day)
9/15 22:11:56 7021 - Connection telemetry fields and analysis usage
9/15 22:11:58 6062 - Lso was triggered
At this time, I am concerned that the network may be temporarily disconnected.
The E495 WiFi adapter (Intel Wireless-AC 9260 160MHz ver23.40.0.4) does not have a setting to disable "large send offload".
How can I disable "large send offload"?
Note that when looking at "Duration" under "Status" in the network adapter's right-click menu, no disconnections seem to have been detected after power-on or sleep recovery, and the time that the connection has remained active is display.
During power down or sleep, I have no problem since I am not transferring data, but the problem is that warning 6062 is logged when roaming.
If this forum can answer that "Event6062 is a problem at the network interface layer and no real disconnection occurs because retransmission requests, etc. are handled at the protocol layer above it," then I can close this question and use this PC without worry.
The following settings have been changed to resolve the 6062 error.
I tried these things, but they did not solve the problem.

Hello,
Thank you for posting in Q&A forum.
Please kindly find the proper way to disable "large send offload" below:
1.Open Device Manager -> Find the adapter -> Right click to open the properties ->Advanced tab -> Property list -> Disable Large Send Offload v2 (IPv4) and Large Send Offload v2 (IPv6).
2.Or you can open CMD window and try below commands to disable it:
netsh int tcp set global chimney=disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=disabled
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best regards，
Jill Zhou

Disable Large Send Offload v2 (IPv4) and Large Send Offload v2 (IPv6).
It is already disabled on the wired LAN adapter; there is no setting item on the WiFi adapter. The problem occurs during WiFi connection.
netsh int tcp set global chimney=disabled
It appears that chimney can no longer be configured in Windows 11.
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=disabled
I have tried this and it does not change the error condition and I get “6062 - Lso was triggered” when roaming.
Incidentally, the network properties show that the connection continues.
