It seems that since December 9th some computers running the Microsoft operating systems Windows 10 and 8 are losing network connectivity due to what appears to be a problem with DHCP and can no longer obtain LAN IP addresses and DNS server settings from their broadband routers, preventing them from reaching the internet and other devices on their networks.
From our experience this week it seems to be affecting mainly DELL and HP machines.
We have found that the most reliable fix seems to be resetting the Winsock and IP Stacks as the Windows Network Troubleshooter seems unable to fix the problem:
The most reliable fix seems to be:
in the Search box in Windows type cmd and in the Search results right click on CMD Promt and choose run as Administrator.
This will run a command prompt in to which you need to type the following commands:
netsh winsock reset catalog
netsh int ipv4 reset reset.log
netsh int ipv6 reset reset.log
Restart you computer
Another way is to try resarting your computer in the following way:
Goto Start, clicking the Power button, then choosing Restart (not Shut down).
