Lost your Internet connection?

Many of my customers have contacted me in the last week because they cannot get on the Internet – they sometimes see a message about not having a valid IP address.

This seems to have happened after a recent Windows 10 update. In every case, setting a static (fixed) IP address has fixed the problem. Here’s how to set a static IP address in Windows, and more extensive article here, which also covers Macs.

If you don’t want to use a static IP address (which can be undesirable on larger networks: every device on the network – printers, computers, etc – needs to have a different IP address, and if you are assigning them yourself it can be hard to keep track) you could instead try this solution:

Open a command box with elevated privileges and type (or copy and paste) these two commands :

netsh winsock reset catalog
netsh int ipv4 reset reset.log

This is from this news report. The problem was first reported on 9th December and has also been reported today on the BBC website.
