I recently changed broadband provider and when the new router arrived I used it with the defaults with no problems.
Today I have been making it more secure, but when I visit different sites the wireless doorbell goes off - bing, bong, bing, bong......
The first time it happened I went to the door and finding nobody there I muttered something unprintable about children and silly games, but it was not them.
I have now had to make a tough choice - doorbell or Internet.
Sorry folks, but I am still here.
