I pulled the plug on my ISP-supplied all-in-one router earlier this year, replacing it with an OPNsense firewall and router running on the Ugreen DXP4800 Plus NAS. While it was certainly a network overhaul with a deep learning curve, the benefits were immediately apparent. It’s faster (from a network management point of view), more reliable, and gives me far more control when it comes to my home network.
