Internet Lan Not Working in Compaq Presario??
I am having offlate all sorts of problems. Second House shift in two months,One net shift and another new connection and i guess im finally settled. My Laptop was giving all sorts of problems. First the internet was not connecting which i later discovered that the Network Adapter for my Compaq Presario V3133AU went missing one fine day. I had confused 1394 adapter to be the one which i used to connect to internet and when i tried to repair that connection it always get TCP/IP not enabled error.
I reinstalled the Nvidia nforce network controller and then all seem to be back in normal in appearance. Problems against started when i tried to set up a lan with my local desktop PC or try to connect directly to the internet, it says connected but i coudnt ping the gateway or other system in the Lan. I could not even ping the modem. After going through many online hardware and networking forums i realised that it was a firewall issue. I Checked the Windows Firewall and also the Active armor firewall which got installed along with the Nvidia network controller. I disabled the active armor and stilled tried to ping the gateway which gave me message saying host cannot be reached.
Finally i decided to go to the settings of the active armor firewall and i was pretty sure that the windows firewall was Off,there was no antivirus installed as i just formatted my system because of this issue thinking it was TCP/IP problem when it gave me TCP/IP not enabled error(If this is the error make sure you are not seeing 1394 adapter or reinstall your network adapter driver once more). In the Home page of the active firewall(you reach there by clicking on the desktop icon of active armor firewall) there is a link called restore factory settings. In that choose Ethernet and Firewall and restore both. After doing this my net and lan was up finally. I turned off both the firewalls, but i could manage to setup the net.
Symptoms
- Lan/Internet Shows Connected, But Ping is not working.
- Internet not working
- Lan not working
Solution
Disable all your firefalls. This can be only because of firewall Issue. Check windoes firefall(some windows update can
automatically on ur windows firefall) and recheck other firewalls.
