Just installed Lubuntu 12.04 on my Sony Vaio VGN-T150 after installing Win XP again; I had Lubuntu 12.04 on the laptop but wasn't getting any CPU fan operation. Tried adding vaiofand but still seemed like the fan was not working, CPU temps in the 60+ range.
Long story short, decided to install Win XP to see if fan worked under Windows before taking laptop apart to check hardware (also wanted to be able to dual-boot, so I figured this would be the easy way to do it and kill 2 birds w/1 stone). Win XP made no difference, so pulled laptop apart and found fan was binding due to crud; disassembled, cleaned, reinstalled - working now. That's when I reinstalled Lubuntu alongside Win XP.
Ever since, wireless is not working in Lubuntu; wireless adapter is Intel PRO/set 2200 and includes BT. BT appears to be operational. etho 0 (wired) LAN port works. In Win XP, in order to use wireless, BT must be off (can't use both a same time). I've turned BT off using BT manager, no change. Wireless switch is on.
I've read many forum posts for similar issues with this wireless adapter, so far no luck in resolving. From what I've gathered, it is not being recognized by Lubuntu.
Heres some data:

QUESTION: Is network:1 UNCLAIMED the wireless adapter???
rfkill list 0: hci0: Bluetooth Soft blocked: no Hard blocked: no
I don't see anything listed for the wireless switch - ???? I know it works because if I switch it off, the LED on the front panel turns off, so hardware-wise I'm sure it's working.
Next I tried:
lspci -nn | grep -i network 02:0b.0 Network controller : Device [8080:0000] (rev 05)
Honestly, not sure what this means exactly, but I think it references the UNCLAIMED network listed previously. So I tried this next:
sudo modprobe ipw2200 lsmod | grep ipw2200 ipw2200 146210 0 libipw 46732 1 ipw2200 cfg80211 178877 2 ipw2200,libipw lib80211 14040 2 ipw2200,libipw dmesg | grep 2200 [ 2165.049453] ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.2.2kmprq [ 2165.049464] ipw2200: Copyright(c) 2003-2006 Intel Corporation
I take this to mean that the driver is properly installed, hardware not recognized or "present" (since comparing this output to those I saw in other posts, there seems to be a few lines of data missing) - ???
Lastly I tried this:
dmesg | grep eth [ 0.063806] i2c-core: driver [aat2870] using legacy suspend method [ 0.063810] i2c-core: driver [aat2870] using legacy resume method [ 1.631372] e100 0000:02:08.0: eth0: addr 0xe0205000, irq 9, MAC addr 00:01:4a:04:82:cb [ 24.708310] ADDRCONF(NETDEV_UP): eth0: link is not ready [ 27.202263] ADDRCONF(NETDEV_UP): eth0: link is not ready [ 27.203933] ADDRCONF(NETDEV_UP): eth0: link is not ready [ 221.820180] e100 0000:02:08.0: eth0: NIC Link is Up 100 Mbps Full Duplex [ 221.820855] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready [ 232.208048] eth0: no IPv6 routers present
Which I assume is just telling me that my wired LAN is working, but not really sure what else this might tell me.
At this point I'm pretty much lost. I'm relatively new to linux, trying to ditch Windows for good!
Not sure why it seemed to work fine on my first install of Lubuntu (32-bit, BTW) but now after the Win XP install and dual-boot reinstall of Lubuntu, no dice. Any help would be greatly appreciated. I'd really hate to have to reinstall Lubuntu again. Could I boot to a live Lubuntu disk and see what happens with that, then try to figure out what is different that allows the live distro to work and not the installed one? Advice on how best to do that (where do I look)? Thanks in advance!
