OK, did you try connecting the laptop directly to the DSL modem? That is; just bypass the router and connect it directly to the DSL?
Does the Internet connection work correctly with this setup? Does it still work with the Windows Firewall?
I understand that you're using the AVG antivirus software (a good choice, in my opinion). Does this version of AVG include a firewall? If not, fine; but if so, please disable that firewall to test this direct connection.
The point of bypassing both the wireless and the router is to try to narrow the possible connections problem list.
If the computer connects normally when directly connected to the DSL modem, try connecting it via cable to the router. Follow the setup directions when going to the
http://192.168.1.1 setup.
Plug in your router modem to your internet modem then you can access your
http://192.168.1.1 If you don’t have your router modem connected you will see the error page. If so, you have one of these two problems: Your IP is not recognized or your default gateway in not found. The procedure you need to follow is: Open Internet Explorer, then:
1. Click the tools menu
2. Click the internet options command
3. Delete the Temporary Internet Files, Cookies and the History.
4. Reset your router modem. You should see a tiny pin hole somewhere in the back of your router modem.
5. Put in a pin (like a straightened paper clip) and press it and hold it for 30 seconds, then power it all down.
6. Restart your internet modem wait till all the lights are on then turn on your router modem.
7. Once this is done, type into your browser:
http://192.168.1.1 and login.
Hopefully this should reset your IP and your default gateway. If this doesn’t work, see if you can find a technical support site for your genetic router and seek another solution to this connection problem.
When replying, please address each question written above with a "?" mark as I need to know the answer in order to go to the next step. If you can establish the normal connection using a cable with the router installed, then we can proceed to the wireless connection. If you cannot make the connection work when connected via the direct connection, then we need to fix this problem first before attempting a wireless connection.
