Here is the story: I have FC4 on a Inspiron 3800 with an orinoco wireless card. The system is a fairly new install, and the wireless was working flawlessly before. I went to a friends house and had to do a standard reconfig to get my laptop to work at the new location. When I tried to reconfig back to my house settings, it will not connect. I have done nothing weird to the config files other that using the graphical tools available. Output of "$ ifup eth0" :
Determining IP information for eth0... failed; no link present. Check cable?
thanks for the help
