In Post #7 your Ethernet interface is disabled or not working or both. You are getting an auto-DHCP default-loopback address, which means your Ethernet wired adapter inside the laptop is failing to obtain an address from Windows.
Your screenshot still shows the wireless connection ENABLED
; remember what I said earlier about having BOTH
wired and wireless connections enabled simultaneously?! That's a NO-NO
You must find a way to disable that wireless connection in order to properly troubleshoot the wired connection.
If you cannot do this, then most likely your Motherboard has failed and must be replaced.
More likely it's simply a virus that got into your laptop that scrambled your Windows networking files.
Also, your Windows7, if that's what came installed on the laptop from the factory should be perfectly capable of running a wired Ethernet connection WITHOUT
the SP1 (Service Pack 1). I say this since if Windows7 was installed out of the box without SP1, and you got wired Ethernet connectivity to the Internet it WAS
clearly working at one time.
The 3 most likely possibilites are:
Virus attacked your windows networking files and disabled your wired ethernet
The Wired Ethernet chip on the laptop Motherboard has failed and must be replaced
Your hard drive is failing or is faulty and is causing the wired ethernet to fail
Normally a SYSTEM RESTORE
or a WINDOWS REPAIR
or a WINDOWS REFRESH
will fill this type of problem.
I suggest you try each of these in order after FIRST MAKING A COMPLETE BACKUP OF ALL YOUR PERSONAL DATA FILES TO EXTERNAL MEDIA ON YOUR LAPTOP!!
If this fails to get the wired Ethernet working; you will have to do a WINDOWS REINSTALLATION
which includes the formatting of your hard drive *erases all data*. REINSTALLATION
of Windows if it does still not resolve the problem means that the Ethernet chip on your Motherboard has failed and that's not repairable.
Or possibly your hard drive has failed; which is repairable at a much lower cost. Motherboard repair is $175-$400 in the US; 2-3 times that outside of US. Hard drive replacement is $100-$160 in US.
You should also download the free MEMTEST
RAM checker program from the link in my signature below and test your RAM one stick at a time for a minimum of 8 passes. If MEMTEST
reports any errors 1 of your RAM sticks has failed and must be replaced. Rerun Memtest and continue replacing faulty RAM sticks. Finally, re-run MEMTEST
once any and all faulty sticks have been replaced for a minimum of 8 passes; this will take 12-24 hrs. if you have 4GB of RAM or more.
If you can't wrap your head around all of this testing, I suggest you take it to your local Computer Pro and pay them to diagnose and repair the problem. This type of problem can take 2-3 weeks to resolve.
