Laptop won't connect to my home wireless network, but other devices (PC, other laptops, phones) can. My laptop can connect to other networks. The problem is that it says it's connected with full strength, but it just doesn't load any websites or anything else that uses the internet. When I disconnect then reconnect, the internet briefly works for maybe 10 seconds then won't load pages anymore (except google sometimes). I have tried windows troubleshoot, system restore, restarting the modem and router. My internet is set to obtain IP address automatically. My laptop had worked perfectly fine for a year and then all of a sudden the problem appears. This problem has been going around for half a year. How do I fix this?

Troubleshooting is trial and error.

1st, can you connect the laptop with a wire? If so then the wireless is suspicious.
Assuming wireless, is the IPv4 properties box set up OK. Primarily, is the IP address set automatically by DHCP or is it fixed? Let DHCP find it automatically unless you intentionally have a different set-up.
Reboot the router to see if it clears up an ARP cache issue
Are any odd port forwards on your router directing normal traffic to the wrong place?
Do you have a USB wireless adapter available? If so, try it out on the laptop to see if it works. If not, don't buy one just for this.
Is a proxy server in the mix? If so and you don't want one then remove references to it.
Is port 80 and/or port 443 closed on your pc firewall?
Reload the wireless driver with a more current one from the vendor
If you're using IE, try a different browser, such as Chrome or Firefox. IE settings are a puzzle to work with if you're not careful.

Good luck.

I would like to collect some logs from the computer to see what we can find...

You will have to download the tools to a USB flash drive on a working computer and run them on the problematic machine.

Save both files to the Flash Drive.

» Minitoolbox log
Run Minitoolbox from the Flash Drive and check the following options:
  • Flush DNS
  • Report IE Proxy Settings
  • Reset IE Proxy Settings
  • Report FF Proxy Settings
  • Reset FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List Winsock Entries
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Devices (Only Problems)
  • List Users, Partitions and Memory size
  • List Minidump Files
  • List Restore Points
Click on Go.

Post the resulting log in your next reply.

» Farbar Service Scanner (FSS) log
Let's check some windows critical services...
  • Run FSS from the Flash Drive
  • Check all the options
  • click Scan
Post the generated log in your reply.
