 Posted: Fri Jul 17, 2015 6:28 pm Post subject: wifi random disconnection problem |
 |
|
I have an old HP HDX Premium Series laptop with touch sensitive buttons on the top of the keyboard for sound adjustment and also a touchkey for turning on-off wifi. I set these keys on my .xbindkeys config file but i didn't need to define the wifi toggle key since it was working when i installed the system.
My problem is that my wifi turns on and off from time to time. Regarding dmesg output is as follows.
| Code: |

output of rfkill list all is when wifi is working:
| Code: |
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
|
when it disconnects, although i don't press the wifi toggle hardware key, Hard blocked changes to Yes. Also i see a lot of keycode errors in the dmesg.
| Code: |
[ 6299.655102] atkbd serio0: Use 'setkeycodes e03e <keycode>' to make it known.
[ 6299.708768] atkbd serio0: Unknown key pressed (translated set 2, code 0xbf on isa0060/serio0).
[ 6299.708772] atkbd serio0: Use 'setkeycodes e03f <keycode>' to make it known.
[ 6299.714846] atkbd serio0: Unknown key released (translated set 2, code 0xbf on isa0060/serio0).
[ 6299.714855] atkbd serio0: Use 'setkeycodes e03f <keycode>' to make it known.

AFAIK rf_kill, comparing to my hardware, is the kill switch for the wifi and bluetooth (wireless devices board).
Check the wiring of the wifi rf_kill switch, thats a hardware switch, teh wifi boards, screws, cables.
if you have a broken cable, you hardly will be able to check that out easily, as the connectors or the small wires in teh cable could have already a loose connection.
When I turn off the kill switch wifi and bluetooth is instantly disabled until I enable it again with that rf_kill switch.
i think this is more a hardware issue but i may be wrong. did you booted up a livecd and checked if it happens there?
check teh wiring of your keyboard, if thats a ribbon cable you need to take it out and put it in, careful they need to be handled special. some notebook manufactuerers provide service / repair manuals.

looks like two different keys are pressed and they seems to be on the isa bus, maybe these events suggest that the rf kill button was pressed and not recognized .. as i do not have the schematics / software of your motherboard i can only guess. it also looks that they are on the isa bus. |
