Do you show an Ethernet/Lan driver in Add/Remove programs?
most of the warnings and errors consist of tcp/ip and dhcp. i see my wireless network connection driver in add/remove programs.
If you are not able to see it in Device manager & it is enabled in CMOS you might contact Toshiba. I have a tablet & lost the NIC in it the same way. I have a 3 year warranty on it so I backed up my files & then sent it off to a authorized repair shop. Works great new.
*IF* you have Norton installed AND you have loaded SP3, THEN this may be applicable
so i'm guessing it is a hardware problem. if that's the case, then i guess i can't fix it by doing a system restore right? But, is it possible for me to set up a wireless network using my laptop?
contradiction: Software (even a SW restore) will not fix a true hardware problem
should be, but be advised that a wired connection is necessary to config the router for a wireless connection
so I won't be able to create a wireless connection using my laptop then, because my laptop is incapable of using the lan.
Unless you can load the drivers and run it as USB connection (some routers have USB option, hard wire)
