Thread: How to 'wake up' wireless interface? HP EliteBook 8540p laptop.

-

after spending day trying 'suspend' (to ram) working on hp elitebook 8540p laptop, got working. took home , brought out of suspend. screen remained black left while, when nothing came of felt obliged power laptop off (hold down power button seconds).

when laptop rebooted, , every boot since, wireless interface seems disabled. not possible use wireless network interface @ now.

according nm-tool, "state: asleep", , according "lshw -c network", "network disabled".

device recognised properly, , various data can read it, seems have somehow got disabled @ fundamental level.

have idea how can re-enable wifi on laptop? not have windows installed can't use afaik. there special /sys file can read/write enable it?

suggestions welcome! anything...

truly bizarre. nothing did got wifi working again (reboots, power-off , wait, messing around in bios) until...

put in suspend again, , when woke up, wifi working!

can shed light on going on here? scripts coordinate suspend/wake-up process? i'd know commands involved 1 of them has restored wireless interface.
