2 days ago I've upgraded my ubuntu to 12.04. It's running dual boot with windows 7 on an acer aspire 8930 which has a intel wifi link 5100.

I now have wifi problems where it constantly switches on and off and has e really weak signal.

Could anybody help.

The Intel WIreless with the Linux Kernel has always not worked well. This is the workaround to get it to work properly:

  1. Press Ctrl + Alt + T. Type in this command: sudo gedit /etc/modprobe.d/intel_11n_disable.conf
  2. Paste this into the gedit windw that opens: options iwlagn 11n_disable=1
  3. Save, and close gedit. When back at the prompt type sudo update-initramfs -u.
  4. Run sudo modprobe -r iwlagn && sudo modprobe iwlagn.
  5. Try it out!

Hope that helps! Source:
