Access control blocking all devices

[John_TheRiver]

The solved reply listed is two years old and a different device. 

The firmware is V2.2.1.210.

The problem didn't show up until I added a Windows Ten HP tower to the network, this followed the death of the Dell Tower on Windows seven.

When three devices are shut off, when they come back on they are blocked.  One is a Roku TV.  

Leaving Access Control turned off is the only work around I've found.

Have you tried removing the access control configurations from Access controls. Setup an IP address reservation for each device that your considering using in Access Control. One this is is done and the router is rebooted. Go back in and setup Access Controls for those devices again?

Well, it's Valentines Day so not today, not if I know what's good for me. 

If it works, it won't answer the question of why adding the new HP Tower on Windows Ten, Pro started it. 

I'll let you know.

Just sounds like a change in something that cuased access control to stop working right. the PC addition could have done this. 

Let us now after the holiday.
