Hi,
At present I’m using a super hub 3 in modem mode with an Apple AirPort Extreme (latest wireless AC version). The reason for this is to get greater wireless range than the SH3 can manage, to cover the whole house, which it does reasonably well.
The problem is that I am getting an issue with ‘double NAT’. Now, I’m a bit of a dunce when it comes to such matters and I generally bumble my way through anything networking related, but I’m told that this is probably because both the SH3 (even in modem mode and it can’t be configured) and the router both have a firewall and both are performing ‘network address translation’. This causes a problem occasionally when the SH3 has to be rebooted because it takes a while for the AE to settle down and get over the fact that something else is also performing NAT; it also causes a more inconvenient issue in that my Plex media server cannot be reached from outside my network (the error message in Plex says it’s the double NAT that’s the issue). I also get some occasional instability with devices randomly dropping their connections (sometimes within my network, sometimes to the internet). Most of my media devices are connected via Ethernet, and have static IPs, so I can’t understand why it’s happening, but I can only assume the modem and/or router are responsible.
So, I thought I’d resolve the situation and treat myself to an upgrade by buying a new modem/router and replacing both the SH3 and AE with a single, premium, device. What I’m after is a router that I can plug the VM coax cable straight into, which has the range to cover a whole 4 bedroom house from one corner of the ground floor and at least 4 Ethernet ports.
I’ve had a look an it is actually very hard to figure out which ones that mention being for ‘cable’ actually have the coax input. In many cases even the photo of the rear panel, if there is one, isn’t clear enough to tell.
Does anyone have any recommendations?
