For one, while factory resetting the hub is generally considered a worthwhile exercise when diagnosing issues, there's a chance that even if you fix the problem it's having, restoring your old settings might just bring it back again so keep that in mind.

Secondly, if you're running a web server and want to statically assign a bunch of devices on your network, then I'd heavily recommend investing in a decent wireless router as the hub just isn't up to the task of dealing with that level of configuration (As you've found out with your headaches). A good router will allow you to assign specific IP addresses per device via DHCP so you don't need to manage devices one by one while also avoiding any IP conflicts from the DHCP server tryng to dish out an IP you've statically set.
Port forwarding is also much less of a headache.

You are exactly the kind of person that should have a proper router. I firmly believe that most people can actually get by with the SHUB (or ideally the SHUB2) but people like yourself are far better off with a dedicated router.

Another advantage of having your own is that you don't have to worry about reconfiguring everything should you decide to move ISP's. Though some other ISP's do try and limit you from using your own router, it's fairly trivial to get around.

In short, do yourself a favour and get a decent router. Put the SHUB into modem mode and then never worry about it again.
