Hi there,

I have a 4mg connection with NTL and it has been running very slowly over the past few weeks on all of the computers on our network. I did the usual of rebooting the router and all the computers but it didn't make much difference. I called NTL and they tested the line and said there was no problem there. Then they tried to access my computer but couldn't as they said the firewall was on. I had turned off my Norton firewall and the Windows one was off.

I then tried on my boyfriend's computer, turned off his MacAffee firewall and made sure the windows firewall was off but NTL couldn't access it. They said that they couldn't help me further and that it was a problem with the firewalls on our computers (although it seems strange that the problem should be affecting all 5 computers and we use different firewalls. Anyway, I tried the computer in safe mode with networking and the internet seemed to be working fine.

I ran some broadband speed tests, here are the results:

My computer is an Acer 5672WMLi
Network cards:

Broadcom Netlink ™ Gigabite Ethernet
Intel® Pro/Wireless 3945ABG Network Connection

Router: Netgear 54 Mbps Wireless Router WGR614v4 - latest firmware installed

It doesn't make any difference whether I'm using wireless or the ethernet cable.

If anyone could give me any advice on what to do it would be much appreciated.

Try a reboot of the entire system including the modem.

Disconnect the input to the modem and ground the hot wire to ground (it will discharge all static electricity (noise) on the line - a tip I learned from a cable company engineer)

Wait several minutes and then reconnect and repower the modem, then the router, then each computer, one at a time.

Go to start/settings/network connections, right click on the connection and choose "Repair".

How is your connection speed now?

I've done that but it hasn't made much difference. On one of the computers when I tried to repair an error message came up and said it coudn't repair, however it did connect to the internet. I've ran Spybot on this laptop and found a Trojan - Win32.small.ddx. I'm trying to remove this at the minute (although Spybot isn't able to). Do you think this could be slowing down the entire network?

Generally a network places more trust on network resources than it does on internet stuff - so I'd start by scanning all of the computers on the network for this threat.

Once the threat has been defeated - then we can start looking for other problems.
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.
