Hello All,
I have a Fujitsu Siemens T3010 Lifebook on which I have Ubuntu 10.10 installed. The installed kernel is 2.6.35-27.
lspci lists the installed network contraller as:
Code:
01:0d.0 Network controller: Intel Corporation PRO/Wireless LAN 2100 3B Mini PCI Adapter (rev 04)
At first glance, the wireless adapter seems to be functioning normally. The problem is that every once in a while the wireless connection gets dropped, and gets reestablished a while later. At times, this happens very frequently.
I have been able to figure out that the reason that the connection is dropped is due to a HW rfkill. The 'rfkill list' command produces the following output following the connection getting dropped:
Code:
0:phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
'Hard blocked: no' is printed whenever the connection is up and running.
The laptop does in fact have a physical killswitch located behind it and needless to say turning it off also produces the same result. However, the loop of the connection getting dropped and reestablished happens even in the absence of physical contact altogether, so it can't be that a slight wobble is being misinterpreted as the killswitch has been triggered or anything.
I have a nasty feeling that the problem may be due to a physical problem - but I want to exhaust all other alternatives before I go digging into the box. Even if it is not fixable, perhaps there may be a way to override the problem somehow.
I am posting a section from my daemon.log that spans a single rfkill loop below.
I would greatly appreciate any help!
Thanks a lot in advance
