Always running recent 13-CURRENT and the hardware is iwm0@pci0:2:0:0: class=3D0x028000 card=3D0x00508086 chip=3D0x24fd808= 6 rev=3D0x78 hdr=3D0x00 vendor =3D 'Intel Corporation' device =3D 'Wireless 8265 / 8275' class =3D network The other Dell laptop has the previous generation of this chip. After using the laptop "normally" (wired or wireless) for a while, it stops finding networks on scan with the result that roaming almost never works (it doesn't find other networks as I move between work-home). I've tested this = with and without lagg failover configured. As soon as I do 'service netif restart' it can again see all networks with 'ifconfig wlan0 scan'. For a while that is. After a short time (sub-hour to hours), scan will show either only a subset of networks or none at all and = the only remedy is to tear down the interfaces and configure them again. --=20 You are receiving this mail because: You are the assignee for the bug.=
