I got a new computer last month as a present. They also installed me ADSL Internet connection. Few of my neighbors and I bought Belkin ADSL router to share that Internet connection. Another friend installed me Torrent software for movie downloading. At the beginning, everything worked fine. Since yesterday, my ADSL router keeps disconnecting and reconnecting. I am sure that I will have trouble finding right firmware for my Belkin ADSL router.
I do not think that your problem has anything with firmware version of your Belkin ADSL router. In addition, I do not think that you will have the problem with finding the right firmware. You can find the newest firmware and drivers on the Belkin site or on forums. I am certain that your operating system is infected with some virus. Its job is to aloud access to hard drive content on your computer to its owner. Those types of viruses are common on the Internet. I also had to reinstall my XP twice because of torrent using. That was at the beginning. However, from my personal experience I found out what to use for protection. The protection that I have been using for last six months is combination of AVG and Seagate Personal firewall and I do not have any problems. First, use AVG to clean all viruses from your computer and after that, install Seagate Personal firewall. I think you will be safe enough after that.
