Hi

I have static ip's on my network with up to 4 machines connected max at a time...usually 3...all connected by Ethernet...

My internet will be working.... then suddenly..usually after a short duration of not using internet it will stop working for browsing...... but it will be working on like Steam friends / MSN for example.....

It seems to be JUST my machine that it is affecting!!

It has been doing this EVERY day without fail at least like twice a day.....for about 3 weeks or so... maybe more....

When i restart pc it is working FINE again.... it seems to just conk out randomly...

Resetting router does nothing.. its just restarting PC that makes it work again....

convinced its a local machine problem .. but for the record my router is bt homehub v.2..

im windows xp pro...

Help - I am wondering if it could be malware related - but I have no viruses / spyware come up when searches performed in s&d, avg, malware anti bytes, super anti spyware....

For the record I have tried going into command prompt and typing Ping ip and also a hostname and got the expected results.. screenshots here

when the problem happens what does the network icon on the task bar say? Also is it just happening to your computer? or all of them in the network.

Uninstall AVG, using AVG Remover and see, if it helps: http://www.avg.com/us-en/download-tools

Since you have to have some protection, I propose, you install ONE of these:
- Avast! free antivirus: http://www.avast.com/eng/download-avast-home.html
- Avira free antivirus: http://www.free-av.com/en/download/1/avira..._antivirus.html

Your issue is with Steam and the BT Home Hub. It is incompatible with Steam, please head on over to https://support.steampowered.com for more information on how to solve this issue.

What is happening here is, that when you refresh the server list in the Steam Master Browser window your NAT Table on your BT Homehub fills up, and kills your internet connection. Its a common issue with BT anything.
