From: Rafael J. Wysocki on 22 May 2010 18:00 Hi, With current -git on Acer Ferrari One the ath9k driver doesn't seem to work after resume from suspend to RAM. NetworkManager seems to think that it works, but it doesn't really connect with the AP and doesn't try to obtain an IP address. Reloading the driver makes it work again. The 2.6.34 (final) version works flawlessly with STR. The user space is openSUSE 11.3 Milestone 6, so it may be somewhat unstable in general, but this particular feature does work with 2.6.34.

Apparently, it can't obtain the address without being reloaded. iwlagn also has problems after resume from suspend to RAM (tested on Toshiba Portege R500). In this case resume works once, but then the next attempt to suspend fails (I had to reboot the box every time that happened). If iwlagn is unloaded, it is possible to suspend and resume the system arbitrary number of times, but then iwlagn doesn't work when its reloaded (it doesn't detect wireless networks).
