WIFI connectivity drops randomly

I have both Wired and Wireless to connect to the routers. All would be fine but after several hours the WiFi drops. The Wired connection is stable. On this reboot, the WiFi made it to 12 hours.

I did a forum search a couple of days ago and in a post quite similar to my predicament, I removed dchp-s6 and dchp along with a couple of other packages. Then I reinstalled network-manager. The problem still persist.

Any suggestions?

Does the fix also apply to wlan0?

Disabling TSO seems to have fixed the problem for me. (I needed to set it after a fresh boot, *before* the interface starts bailing out continually.)

How do I disable TSO?

To disable TSO check https://man.archlinux.org/man/ethtool.8.en#tso

As this is the first report about randomly dropping WiFi connections there is no guarantee the mentioned fixes will help, so the only way to know for sure is to test.

Thank you for the link. I had to install ethtool. I do not know how to read but it seems to me that ...

Code: [Select]
~ > ethtool -k wlan0 | grep tcp
tcp-segmentation-offload: off
        tx-tcp-segmentation: off [fixed]
        tx-tcp-ecn-segmentation: off [fixed]
        tx-tcp-mangleid-segmentation: off [fixed]
        tx-tcp6-segmentation: off [fixed]

... TSO is already disabled.

Nevertheless,

Code: [Select]
~ >sudo ethtool -K wlan0 tso off
[email protected] ~ > ethtool -k wlan0 | grep tcp
tcp-segmentation-offload: off
        tx-tcp-segmentation: off [fixed]
        tx-tcp-ecn-segmentation: off [fixed]
        tx-tcp-mangleid-segmentation: off [fixed]
        tx-tcp6-segmentation: off [fixed]

returns the same. Any other ideas?
