Several times a day, my Internet connection stops working on my Windows 8 computer (it's not the network, other computers on the network work fine). It happens on all of my Windows 8 computers (individually, not at the same time) and doesn't fix until I flush my DNS.

All three of the computers have their settings synchronised through my Microsoft account.

Does anyone have any ideas on how to fix this?

  Where is DHCP enabled (The router)? Is the DNS dynamic or static in the LAN adapter properties (+1 good clear question)?

  @Psycogeek The only disruption is in resolution. Active connections are fine, and so is pinging by IP. As I said in the question, it happens several times a day. Browser is irrelevant as it affects the entire computer. I don't have any additional software being used to connect to the network.

  @DaveRook DHCP is enabled on the router (just a wireless home router), DNS is set to dynamic on the LAN adaptor (setting to static isn't a solution, as two of the computers this affects are used on networks that filter external DNS requests).

  Can you try the same thing with safe mode? I know it's horrible to work in but it may help to pin point possible issues

  Also, try adding the DNS servers... Set the first to point to your router, but set the second to 8.8.8.8 just to see what happens. Next question, how many computers are on this network? What are the OS's that are resolving fine? I assume yo have no server

Use the following process:

• Check the router memory in the router logs


• Limit the size of the DNS cache in the router settings


• Upgrade the firmware on the router


• Set the router to auto-reboot in short intervals to avoid manual flushing
