Hi Guys, I hope someone can help me with this.

I have an Archer D9 where I keep getting DNS errors. When I run the Diagnostic it tells me NCIS has failed. Sometimes this is a brief problem and it sorts its self out, and other times I actually have to restart the router. It happens across multiple devices from Phones, to laptops and desktops and doesnt matter if the device is wired or on wireless.

Hardware: Archer D9 v1 00000000
Firmware: 0.9.1 0.1 v0041.0 Build 150826 Rel.42046n

Ive tried lowering the MTU settings but that didnt help.
Tried resetting to factory default and only setting up the ISP info, but also no change.

Some people have suggested that this is possibly a problem with the firewall, but Im a little cautious playing with that as I have almost no experience in doing it.

Anyone have any suggestions or fixes?

Thanks
