We have a very mysterious problem.

There are dozens of computers that use our network without any problems. However, 6 HP laptops get kicked off the network after 3 minutes like clockwork.

- after they get kicked off, the default gateway is missing from ipconfig
- all 6 laptops work fine on other networks
- they get kicked off both wired and wireless in exactly the same manner
- HPs are 2 different models, Pavilion dv6-6C50US and HP ENvy 15
- we have others of these same models that work fine on the network

router is a ZyXEL ZyWALL USG200 configured for DHCP
router and all PC's are completely up to date with all patches

we have tried:
- hardcoding the default gateway in TCP/IP settings
- adding and removing network cards in device manager
- disabling Anti-Virus

Try disconnecting from the network a non problem laptop and connect only one problem laptop. What happens after 3 minutes?

Thanks, but it turned out to not be a problem with the network but on the PCs. We booted into safe mode with networking and it stays connected fine that way. Clearly there is some sort of software causing the problem. We are now looking at disabling the many pre-installed HP utilities or perhaps norton or bonjour.
