GS308EP - Can it handle gigabit fiber well? Or is there a better choice? Slow gig internet!!!

Out of the fiber modem, it runs into a Watchguard T20 firewall that I'm using as a router/firewall.  From there, it runs out the lan port to the netgear switch.  Out of the switch, I have it running to a Cisco 150ax access point.  It is an access point only.  No routing at all.  No double nats.  I hate double nats.  The access point is 802.11ax wifi 6.  I then have I think 4 range extenders around the house.  I also have a CAT 6 running from the netgear switch running out to my garage to another two netgear switches and a cisco 150ax access point.

Yes, you can connect the T20 WAN/Internet port direct to the fiber box. Best guess, there is not just the fiber (which does the link form the ISP to the fiber box), but also a Gigabit copper Ethernet port for this purpose.

Avoid wildly mixing up WAN (with the publilc IP subnet) with the rest of the LAN. The only connection is the T20 which should be configured as the one-and-only NAT router, and having the RFC1918 private LAN IP on it's LAN side. From there you can connect to the switch, to the wireless AP, to a NAS, ... whatever.

In plain Firewall NAT routing, the T20 should be able to handle about 510 Mbit/s on mixed traffic, or up to 1.7 Gbit/s on UDP (more a theoretical value). The performance of the T20 will be much lower on operating VPN (something around 400 Mbit/s max), HTTPS with IPS enabled, or when you consider to keep up the Antivirus inspection on the T20.

Range extenders? Wireless range extenders? When it comes to performance this reads fishy at least. Tell us more if you want an estimate on the performance loss ...

There is goes your wonderful Gigabit fiber performance my friend.

It's certainly not the GS308EP, which does handle wire speed switching with ease.
