D-Link wi-fi router often disconnects from ISP
A friend of mine has a D-Link DSL G604T wireless router at home and uses it to connect two notebook computers to the Internet.
Since the 26th of December, he can't connect to the Internet. He contacted his ISP and they told him that his connection is being reset every 1:30 minutes.
They suggested that it might by some software that's doing it, but he told me that nothing new is installed on the machines. He also told me that this happens if some of the two notebooks tries to access the router, no matter what.
Do you have any ideas of what this can be?
Thank you all.
