I am running FC1 on an old IBM 500mhz Athlon K6 processor Aptiva with 192meg ram using an SMC USB wireless 802.11b adapter. Everything works great except when I try YUM to update my system. Every so often it will hang on a large file download and the only way I can get it to continue is to kill off YUM and restart it. I do have three mirrors listed in the YUM configuration file. FC1 recognized my wireless USB device, but to get it to work I did have to manually create the wlan0 configuration file. In the wlan0 file I have the rate defined as adaptive instead of being a set speed. Right now I do have all the latest updates applied to this machine, it would be nice though to be able to run YUM and know that it will finish without hanging. Has anyone else experienced this or have any ideas? Thanks.
