I have a HP Pavilion laptop that has 1.83 ghz processor with 3 gig ram. It is running Vista Home Premium. I have been connecting to the internet through a wiresless connection and it has worked fine, then it just stopped connecting. There are others in the house that connect fine and I have taken it to work where we have a wireless connection and it will not work. It see the network and sometimes it says it is connected but just local. I have tried doing a system restore and that didn't help. I scanned with malwarebytes and found some things and scanned with avg and it is all clean. Still doesn't work. I tried connecting through a wired connection and that doesn't work either. I tried to reset winsock by doing the netsh winsock reset catalog and then reset the IPv4 tcp/IP with netsh int ipv reset reset.log and reset IPv6 tcp/ip netsh int ipv6 reset reset.log then rebooted, but nothing works. I did all that by running as administrator.
Any help Please.
Have you tried resetting your wireless router by unplugging it? Maybe it's just an IP problem.I have reset the router and tried it on a couple of routers that other computers work on.This is not a router problem. The fact u can not connect with a wired cable leads to a laptop issue. try a few simple troubleshooting steps.

1- Preform a check disk FIRST. Hey, this is windows and check disk have been known to preform miracles.
2- uninstall the existing drivers and reboot.
3- download and install the latest and greatest drivers for your LT. Once install reboot.

Write back and let us know the out come.Have you tried connecting directly to the MODEM? If not, do so and see if that works before we go any further. And to CORRECT the post above this one, it could still be a router issue even if a wired connection from the router fails.Allen, danldo posted
"I have reset the router and tried it on a couple of routers that other computers work on."

Thats why I went with the uninstalling/installing driver troubleshooting steps and by pass the modem.A direct connection to the modem is the correct first troubleshooting step.I just connected it to the dsl modem and still doesn't work.
Yesterday I ran a chkdsk and that didn't fix it.
I also down loaded the most current driver and installed still nothing.
I uninstalled rebooted and let it find the device and install, still nothing.
Okay. Try scanning with something other than AVG. Download Avira or Avast or Bit Defender (free version or trial version) and run a scan. DO NOT run two av's resident simultaneously.Are you able to obtain an IP address from the router/dhcp server? If not, you're not going to get anywhere..

open a command prompt and type: ipconfig

What's the status?Here is my IPconfig

Look next to where is says, "network adapters". What is the status of the wireless and wired network adapters? Are there any errors or anything unusual?

I had looked at the adapter and everything looked good. I had uninstalled and reinstalled, and even downloaded the latest drivers, but still didn't work. I finally gave up and reloaded the computer and now it works great.
Thanks for all the help.
