My home network has been on Verizon Fios for nineteen years. As was pointed out not too long ago, the speed was originally 15 Mbps, coming over a D-Link Ethernet-only router. Screaming fast for the time, but not even qualifying as broadband anymore.* Besides my office, I wired a couple bedrooms with Ethernet.
Later, when Verizon added Fios TV, an Actiontec router showed up with MoCA networking and Wi-Fi. With that upgrade, 20 Mbps was in the house for a long time.
Later, Verizon replaced the 1st generation Optical Network Terminal in the garage. It came with the big breakthrough router, a Verizon Quantum Gateway. I ran 100 Mbps for ages, and finally kicked up to Gigabit Internet some months ago. Do I need that much speed? Nah, but I had to make Verizon justify a price increase.
I repurposed the Actiontec router as a Wi-Fi hotspot in the guest room by assigning it, and its DHCP range, a different IP subnet. The 192.168.2.0 network uplinked to the Gateway’s 192.168.1.0 network and out to the Internet from there.
Now that I have latest Verizon router, I’ve replaced the ancient Actiontec with the still-excellent Quantum Gateway, using the same subnet trick. Wi-fi performance is vastly better than it was with the Actiontec.
It would be nice if the Gateway could act as an extender on the same subnet, but it doesn’t do that. As far as I know, anyway. The only potential limitation is with products that need to discover each other with broadcasts on the same subnet. I’m looking at you, Google Chromecast.
Does this mean I’m an advanced technical user? 😉
* My first broadband connection, in 1998, was over Roadrunner at T-I speed — 1.5 Mbps. So of course running ten times faster was considered blazing fast.
