[Bug 664735] Re: Suspend/hibernate loses access to wireless access points

[Wolfgang Kufner]

** Description changed:

- Under Ubuntu 10.10 UNE, If I suspend or hibernate, coming back from
- either, system can't locate any wireless access point - even if I'm
- actually sitting right next to it. Have to reboot for any to be
- discovered. I always make sure to disconnect first before doing
- suspend/hibernate.
+ [EXPLANATION AND WORKAROUND]
+ With ubuntu 10.10 some hardware that was previously driven by the rt2860sta driver is now driven by default by the rt2800pci driver. Sometimes the new rt2800pci does not work as well as the rt2860sta. In that case it is often possible to switch back by blacklisting. See how to switch between the drivers here: https://answers.launchpad.net/ubuntu/+question/132350

+ [ORIGINAL REPORT]
+ Under Ubuntu 10.10 UNE, If I suspend or hibernate, coming back from either, system can't locate any wireless access point - even if I'm actually sitting right next to it. Have to reboot for any to be discovered. I always make sure to disconnect first before doing suspend/hibernate.
  
  I do have a swap partition,  3GB in size (1.5 times my system RAM).
  Suspend and hibernate do function correctly.
  
  Hardware is ASUS EEE PC 1000, 2GB RAM, 40GB SSD. Note: this never happened with EasyPeasy 1.6/Ubuntu 10.04 on same box.
