My SG-3100 came in Yesterday. I've been banging my head against the wall trying to configure ports 1 & 2 to be part of a Link Aggregated Port to connect to the switch. I finally seem to have figured it out but it's been 4-5 hrs of resetting the 3100 to default settings because I kept getting locked out of the LAN. However during the process I've come to really like the flexibility of pfsense. I see a lot of finely tuned customization opportunities and OpenVPN remote access.
Nice! I finally bit the bullet and ordered an SG-2100. It came last week and it's just been sitting on my kitchen table. Just need to find the time to "break" my network so I can improve it. Out of curiosity, how did you approach initial config? The way Netgate recommends? Connect WAN interface to ONT/Modem then connect to a LAN port via Ethernet to a mgmt computer?
I'd recommend to look into Eero. managed from a smart phone and is pretty good for me after I increased my plan with FIOS to 1gb/s
I ran an Eero setup for years until we moved and I had wired ethernet drops run for access points. It's a nice plug and play set up and surprisingly fast. Control isn't super granular though (by design I'm sure), you can't shut off SSID broadcasting, and I did have issues maintaining a connection when roaming between APs. I gave the Eero to my parents and they love it though. It massively improved their pathetic WiFi situation. I would recommend it to anyone who just wants plug and play.
