 |
|
Hi, I have found out that I cannot connect to any wireless network unless I have my laptop connected to AC power. I have a thinkpad t420 with intel | Code: | | 03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 (rev 34) |
wireless card. What output should I post that could be even a little bit relevant?

sys-apps/pciutils-3.1.9-r1

I would really like to know why is this happening. I have been messing around with udev, but I've reverted everything and it was just a coincidence I was running on battery the whole time I tried to know why I cannot connect to wireless network. (hence my post in the sticky "udev" thread in this forum)
I think it is power related, the wireless card either does not have enough current or voltage running on battery. (it definetely is not HW issue, since I've tried connecting to wireless network with windows and there wasn't even the slightest hint of failure)
EDIT: I have found that whenever I disconnect the AC power, "iwconfig wlan0" says "Power management: on" and with AC connected it says off, I've tried manually changing that and it does not help. |

| I think there is no need of AC power to connect with a wireless system or wireless devices.As i have connected all my wireless security devices with my laptop and even i have lost the power i still get the alert on my laptop.I think you must check your LAN board i think it may have some problem. |

first of all: thank you for your reply
second: I have solved this issue like a year ago
third: I have like 3rd laptop since then
fourth: I should have marked this thread as "SOLVED" (but I was - still am - too lazy to write down the solution) - sorry for that
fifth: I do not recall how did I solve this issue - I think different kernel and different ucode-firmware package ... but who knows |
