PC Problems

October 24, 2008

Steve had a problem whereby he couldn’t browse the net on his home network. Here’s some possible causes.

Restarting the PC and Modem/Route:

This should always be the first thing you try and is usually the cure for most problems!

ISP (Internet Service Provider:

If the above doesn’t work and you still can’t see ANY sites at all then give your ISP a quick call on their Tech Support line and see if there’s any problems with them that are out of your control. If not, check the following:

Router:

Unplug the main cable supplying your router with the internet signal and plug it straight into your laptop then check the web again, if it works it may be a problem with your Router Configuration so check the router manual.

Antivirus:

Certain Viruses and Spyware can block internet connection for everything but their own needs so install a good anti-virus program, update it and scan.

Network:

If you have a home network, check that its setup correctly by running the Network Setup Wizard on all? computers (Start – Control Panel – Network Setup Wizard)

Firewall:

As in Stephen’s case the problem was most likely caused by either a hardware or software firewall. A firewall program such as Norton Internet Security may be over zealous in blocking internet attacks and end up blocking everything! Check your firewall exemptions or turn it off altogether temporarily to see if you can get back online.
