Last night I installed a LinkSys Wireless G Broadband w/ Speed Booster router to work with a used PC I bought from a friend that already had the proper adapter PCI card installed. Everything appears to work just fine - expect the the hard drive is accessed every two seconds and I'm concerned that the hard drive will wear out. When I disable the wireless adapter card (going back to wired connection), the hard drive access stops - only to resume again when I re-enable the adapter. I did not get the software CD that may have come with the adapter card when I got the used PC and so, I'm unclear if there is an installation step that might be required for the adapter. Again, the wireless connection appears to work great when enabled. Anyone have ideas as to a setting or something that I can check to stop the repeated and frequent hard drive access? Thanks!
