I'm running a Firebox T10 on my home network. I use one subnet for the house and the second for work. In the past few months I've noticed the house subnet often has issues accessing IPv4-based websites (no problem with IPv6 addresses) and my WiFi is in shambles. However, if I bypass the Firebox, some of the problems go away -- I can reach the Comcast Gateway while I cannot access the WiFi that's behind the Firebox.
I'm running mainly Win10 systems (some game systems for the kids, one Linux laptop plus cell phones) -- about 30 devices in total. I have three questions: Has the T10 simply run out of gas to handle WiFi 5/6 and would an upgrade to the T35 solve the problem? If I upgrade to the T35, can I just copy over my configuration file from the T10 and use that? I'm no network engineer -- I just write about them.
