Can't connect to LAN

Sorry.

The USB can be connected to most modems (modem driver required)
This may not help when connecting to a Network hub!

It just sounds as though you may have a hardware fault on the Lan

i'm guessing there's nothing i can do. Thank you very much for trying though. There's something else too. Before the windows screen starts up, my laptop usually restarts itself before it gets to the windows screen.

You never answered if Lan has been disabled in CMOS?

Regarding Windows consistantly restarting. have you tried Safe Mode only?
If Safe Mode works. it may be just a faulty driver issue.

Also you might be able to backup in Safe Mode, and consider a System Restore (to when the Lan actually worked) or possibly even a full re-install of Windows.

I say this (Re-Install Windows) just to 100% confirm that it is hardware related

i disabled the lan but then i dont know what else to do. if it is a hardware issue, would the lan still work after i did a system restore? And safe mode doesnt work, usually it would take almost twenty times of me turning on and turning off the laptop before i could reach windows.

the wireless capability works and i was wondering if, for the time being, i could create a wireless internet through my laptop. But i was reading the instructions for my netgear router and i'm thinking that the lan must be connected, which is a problem. So i was wondering how do i create a wireless connection, if possible. Thank you.

with this much trouble, your System Logs should have some good info for us;

run->eventvwr.msc

start with System
look for Errors, then Warnings. The little document button will copy to the clipboard
so you can paste as a follow-up.

Also investigate the Application Log

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)
