It's a bug related to DNS handling getting blocked by the firewall. There's an Asus engineer on the case.guess I'm retarded can't get the guest network to work it will connect but no internet access had to ho back to the old 288.4 .The android devices my kids and wife use need some QR queer code to use the network Guest network is needed because wife and kids have over 200 hits on malicious sites that were blocked , don't need to take chances they could infect the network OR ROUTER
