They gave me a router with weak Wi-Fi that often drops. I considered replacing it, but it needs a PON port, which isn’t ideal. A wired setup would be better for me.
I believe purchasing genuine access points like the Ubiquiti NanoHD or AC AP Pro is the best approach. It may need some configuration, but it’s worth it if you consider it.
It seems you're dealing with Fiber connectivity options. Unless your provider installs a separate ONT, you'll likely need to use that device. You might find a bridge or IP pass-through mode available, but this depends on the equipment and ISP policies. If the Wi-Fi performance is poor, consider replacing it with a wireless access point in your ISP's box—it’s probably the simplest solution. For reference, routers with Fiber support aren’t available for sale in stores. Some users have tried using PFense devices with fiber cards, though this usually needs special cooperation from most ISPs.
