After moving, I can not get my Dell Latitude running FC6 or my Dell Dimension running Debian 4.0 to connect to my router. Neither had problem before the move. I have an HP Pavillion running Vista that has no problems connecting. I have tried playing with the settings in ifcfg-eth0, but not successfully. I have tried two different routers, neither work with my linux systems, both work with windows. Bypassing the router completely also does not work.
My network adapter is 3com Corporation 3c905C-TX/TX-M [Tornado].
My router is Linksys Etherfast Cable/DSL Router Model BEFSR41 ver. 3.
ifup eth0 gives
Determinging IP information for eth0... failed.
dmesg | grep eth0 gives
eth0: setting half-duplex.
I don't know what else to try, or what other info could be useful. Thanks in advance for any help.
