I had a pretty stable Natty install, but then I went and upgraded to 11.10. It went downhill from there. Most of my problems I am about to describe are covered in various threads but none of the solutions have worked for me.
I have a Asus laptop model no: U56E-BBL5 with 6gb RAM, Intel core i5
1. Wireless/wifi stopped working. Outputs from various commands suggested in other threads are pasted here

[/CODE]So, wireless is completely not working now and I have to sit near by shoe closet on the floor to get a wired connection to post this.
2. Suspend hangs the system.
Whenever I suspend or system goes to suspend due to inactivity, the system completely freezes. Only a hard reset is possible at this time.
3. System is generally slow and unreliable. Only saving grace has been Gnome3.2 which looks rather neat.
Any help is greatly appreciated and any one else having same problems please give a shout. I would feel a little better knowing that I am not alone having these problems.
I have the same system and the same issues. I found a workaround for the wireless issue in this thread:

The *temporary* solution involves installing an older kernel, it seems we have to go back to kernel 2.6.38 to get it to work. The most recent version of that kernel can be downloaded from:
http://
According to the helpful person from that thread you will need three files:
linux-headers.
and either:
linux-headers.
linux-image.
or:
linux-headers.
linux-image.
... depending on your architecture (32-bit or 64-bit). Once you have the three files just double click them to install using the Software Center and restart you system remembering to select the older kernel in Grub. Unfortunately this does not resolve the suspend issue.
