My wifi signal disconnects at random. Everyone else's computer on the network works well, so it's not a network fault. It works well on Windows so it's not a hardware fault. Relevant lspci output:

02:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 130 [8086:0896] (rev 34)
    Subsystem: Intel Corporation Centrino Wireless-N 130 BGN [8086:5005]
    Flags: bus master, fast devsel, latency 0, IRQ 44
    Memory at e1500000 (64-bit, non-prefetchable) [size=8K]
    Kernel driver in use: iwlwifi
    Kernel modules: iwlwifi

I tried downloading the latest 3.2+ drivers from the intel website, called iwlwifi-6000g2b-ucode-, and replaced the file in /lib/firmware, but it didn't help.

What else can I do? There are many conflicting suggestions on the internet, I tried doing the fix where I made an entry in a new filemodprobe.d/iwlwifi.conf to switch of i1n network, but that simply disabled all wifi support when I rebooted.

May we see: cat /etc/modprobe.d/iwlwifi.conf? I suspect there is a typographical error there. –  chili555 Jan 24 at 17:28
I had put in: options iwlwifi 11n_disable=1 into the file, @chili555. I got it from here. –  aditya menon Jan 24 at 21:19
Was the file really new? Did you put it in modprobe.d/iwlwifi.conf or in /etc/modprobe.d/iwlwifi.conf. In recent kernel versions, the file is not empty. Please detach the ethernet, reboot and try to connect and then run: dmesg > wifi.txt. Find the file wifi.txt in your user directory and paste it here and give us the link in your reply: paste.ubuntu.com –  chili555 Jan 24 at 21:24
Yep, there is no such file chili. Here's what's there. (thanks for working on helping...) –  aditya menon Jan 24 at 21:28
Please let me see dmesg > wifi.txt as above and we'll proceed from there. –  chili555 Jan 24 at 21:29
