Vista - ISP, hardware or software issue?

I have been having an intermittent range of internet connection problems with my computer running vista home premium over adsl.

Initially my connection would drop out over night and in the early hours of the morning and if I browsed for too long /opened too many sites simultaneously my connection would cease to work. The internet would appear to be still connected in the MS icon in the tray (a globe showed over the two monitors). When I asked vista to check the connection/repair it told me that it was a connection with the ISP.

After a few frustrating weeks dealing with the ISP they admitted a fault and said they would fix it.

My connection no longer drops out (I never lose the globe in the tray) but the problem where excessive www browsing stops the browser working. I have tried IE, Chrome, I have disabled my firewall, reset the network adapter, bought a new router, reset the old and new router but the problem persists.

I'm sorry if I sound vague

Any ideas?

are you using a wlan connection or LAN

Give us, well, the gurus that is a run down of your specs and network devices. otherwise, they will only be speculating and/or won't help much.

Hello i know i have title newbie but there is no need to insult anyone, I am here to try and improve my troubleshootong skills and i think that i could be of service to people also

We must of have been typing at the same time, I didn't mean to offend. I am, by far, a pc guru and I also try to help whenever I can to give back from all the help I receive here. Networking is not an easy thing for me so I tend to let others help.

Again, what I said was not ment towards you but to the OP.

No worries this is my first time being a part of a fourm seems really cool to be a part of a community but i was always hesitant to join a fourm becasue seemed to act a bit uppity but vistafourms is the best so far
