I partly just want to run this by some other people before launching into another round of troubleshooting.
I've been running KDE on this machine for over a year, and had zero problems. I recently moved and am having to use wireless Internet on it, and only started having any problems after that.
The machine itself is a Gigabyte mobo with a Phenom II 965 x4 processor and 8GB of DDR3 RAM.
Because of the amount of RAM I have been running the most recent PAE kernel, non-BFS. (For whatever reason this machine seems faster without BFS than with it.)
The wireless adapter I am using is a Linksys WUSB54g version 4.
When PCLOS loads it sees the device and loads a driver, but it has crazy packet loss and is not actually usable. To get around this I loaded the Windows driver using NDISWRAPPER and it actually connects well.
The problem I have been having is that the machine will just lock completely at random intervals, with mouse frozen and nothing responding. The only way I have been able to get out of it is to hard reboot, and due to this I did run fsck from a live CD today to see if any issues had resulted. It did find and fix errors, so I was hoping the problem was temporary.
I booted up again, had to configure my network to use the Windows driver, and the machine locked solid an hour or two later, requiring another hard shutdown.
The same adapter is working fine while booted into Windows on the same machine, although not with the driver that Windows Update had me update to, oddly enough.
My questions are:
1. Is it possible that running NDISWRAPPER and a Windows driver with the PAE kernel is causing this?
2. Rather than using the Windows driver is there something else I could be doing?
At this point I am going to need to fsck the drive again, and I am getting concerned enough I will probably run a diagnostic on the hard drive itself. The hard drive was certainly healthy and had been running with no problems prior to the move, although that was always on a wired connection.
Aside from checking the hard drive I am considering hassling with setting up a router as an access point so I don't have to deal with a wireless adapter at all. Before mucking about with that I thought I would ask to see if anyone had any additional insights.
