How do I connect laptop to internet through the ethernet cable?
my 3 year old Dell Studio laptop connects fine via wireless to home router and internet; but I cannot connect through the ethernet cable. I've done the troubleshooting; disabled/enabled the network adapter; updated the drivers. I'm using an ethernet cable which normally connects an XP, so I know the cable's fine.
Device Manager says the Realtek PCI-E Gigabit Ethernet Controller is working properly. I found the Receive Side Scaling value Enabled, so I Disabled that. Shut off radio for wireless Centrino adapter. Disabled wireless adapter too. Restarted not only the laptop; but also did a shutdown then restart of the entire FIOS with Asus Access Point home network, with all devices shut down. Checked BIOS setting, didn't see any setting Disabled that appeared like the ethernet controller.
Can't do system restore; I did a Repair installation of windows 7 Home Premium last week...but even before then, the System Restore failed every time. I've never been successful at getting a system restore to work on any XP or 7 pc I've tried it on, even though it's enabled and purports to work.
The laptop had been connected primarily, maybe even exclusively, via the wireless, for 3 years...so I"m not even sure the ethernet has ever been connected before.
I'd hate to buy a new ethernet controller card if i don't have to, only to have the problem be software...
Any ideas? thanks!
