AC2600 keeps blocking iPad
This router has been running well with no issues until my wife brought home her iPad.
The firewall keeps blocking her brand new device due to DoS attack, and I really don't want to turn off the DoS protection. I am able to unblock her iPad, but it's randoim and annoying!
Another issue is that I've tried assigning IP addresses to all our devices in our home so as not to let anyone else join the network, but it works pretty poorly and devices keep creating new MAC addresses even though we turned that feature off and try to renew the ( Android & Apple) ip addresses.
Can anyone advise best robust approach(es)
