Hello there,

I am running a wireless network at home, with a PS3 and a laptop using the wireless connection. The PS3 is working fine, but a couple of weeks ago the laptop started saying "Acquiring Network Address" and the internet stopped working, even though the signal to the router was full strength.

Now my main PC is having problems. Since yesterday, none of the programs on my PC can connect to the internet -

Filezilla - ECONNREFUSED - Connection refused by server.
Ad-Aware - System error: 1810 has occured. Description: Service is not online. Application terminates.
Firefox - The connection was refused when attempting to contact www.awebsite.com

...everything except for Internet Explorer (which occasionally works fine, albeit a little sluggish). Firefox did a forced update to 3.0.6 a few days ago and that stopped Firefox working, now it always says "The connection was refused when attempting to contact www..." I have completely removed it and reinstalled it with no luck.

About my system:
Packard Bell
Windows Vista Home Premium
AMD Athlon64 Processor 3800+
768 MB Ram
NVIDIA GeForce 6100 nForce405

I have performed a system restore, back to January and before these problems, but that didn't work. I have downloaded Avast! but that just served to disrupt the IE connection.

The weekend when the laptop stopped connecting properly, my ISP's (Tiscali) local exchange went down. I'm not sure if that would be anything to do with my problems because I don't have that kind of technical knowledge.

I honestly don't know what to do, it won't just sort itself out and I'm totally at my wit's end!

Any help with this matter would be so gratefully received.

Thanks very much for reading this, I look forward to your replies. If you need any more info from me, just ask. Smile

The first thing to try is rebooting the router. This is done by disconnecting the power for a minute and connecting it back up again. The wireless connectivity will probably take a couple of minutes to come back up.

What make and model of router do you use?

Hello, and thank you for your prompt reply.

I just tried disconnecting the router from the power but it's made no difference.

The router is a Belkin Wireless G Router F5D7632-4.

Right now I'm running Windows Defender, avast! and SuperAntiSpyware to find any malware/viruses/other nasties, but as I don't tend to download anything other than from official websites I'm not hopeful of finding the problem with this path.

Does this PC show that it is disconnecting from the wireless network like the laptop does?

Nope, the internet connection is strong and constant on the PC.

That is showing that you have a solid connection to the internet at the time of doing it. If the browser was unable to connect then it is probably a firewall setting.

What software firewalls do you have installed? As a temporary measure, try turning off your firewall and see if you can browse. It is not recommended to keep the firewall off, however your router should offer ample protection for this test.

Turning off the Windows firewall does nothing for the connection, but I see in my control panel that I have two firewalls. One belongs to Norton Internet Security 2007, a program which I tried to delete, as it came with my PC and also just doesn't work, with no luck the other day. Could be a problem with that, I guess.

Any ideas how to cleanly remove it without a product key?

You should be able to remove it via Add/Remove Programs. You need to remove any entries for Norton and Symantec.

Hey there. I've tried that, but the uninstaller just hangs if I try to use it, then when I shut the uninstaller down, Windows tells me it has been successfully unistalled and removes it from the Add/Remove list... Until next time I turn the PC on and it's there again! Sneaky buggers!

Could I just delete the files from Program Files, or would that mess up my system?

Alright, so I decided to delete all the Norton and Symantec files from my PC and IT WORKS! It turns out that their firewall (that I never asked for in the first place!) was blocking every program from connecting to the internet.

Thank you for taking the time to help me, you've been a great help.

Thanks again
