Well, I hope it comes here soon. I just Gigabit internet access and it was a real eye opener. Yeah, pages load instantly now (on fast computers), but the 1/2 second delay wasn't such a huge deal on slower speed internet access.
The eye opener part though is how it brought my Airport Extreme to its knees. I thought I'd be OK since the AE is rock solid and I get internal real-world speeds over 800 Mbps (with large file transfers). Furthermore, when it gets an IP address via regular DHCP (like on cable internet) it's happy, getting 700-800 Mbps on the network. However, I wasn't able to get more than about 225 Mbps using PPPoE. It turns out measured max speeds out there on PPPoE are about 250 Mbps. Furthermore, it often has difficult establishing a PPPoE link with this network. Dunno why since PPPoE worked perfectly on the same network on VDSL2, but I wonder if it has to do with the speed and some other compatibility issues. I can allow the gateway to serve an IP address to it to get back the speed, but then it is doing double NAT.
BTW, my new gateway/modem is a real beast. It is the Sagemcom 5566, which is a custom product for Bell Canada, but rebranded as the Home Hub 3000. It has twelve antennae for two 5 GHz and one 2.4 GHz transmitter I believe. The reason for this is it actually reserves one 5 GHz transmitter for TV, since my IPTV receivers are either wired Ethernet or else WiFi based, with no coax support anymore. The other 5 GHz and the 2.4 GHz are for regular client devices on a different subnet and it's pretty damn strong. Probably stronger than my Airport Extreme. I also has the ONT for the optical fibre built-in, and it also has a built-in battery giving it up to 6 hours internet access even with no power.
The problem though is it's still one access point, so it's still weak at the end of the house. And at least with the mobile interface the configuration is very limited. I'll have to check out the desktop interface, but I'm not that optimistic.
What about Google WiFi? How good is its performance for PPPoE?
What about its configurability? I want to have a restricted DHCP range since I have some machines on static IPs in the same subnet. I don't need complex management tools but I'd want at least simple port forwarding capabilities. QoS doesn't seem like a major need though at this time since the 1 Gbps on my setup is never even gets close to being saturated.
BTW, the modem's self speed test clocks in a 1.29 Gbps down, and 130 Mbps up. I can get the Airport Extreme to about 800/115 but once I use PPPoE it's more like 210/110.
tl;dr:
Airport Extreme does not do well with Gigabit PPPoE with my optical fibre gateway. It sometimes has PPPoE authentication problems, and even when it authenticates, it maxes out at 225 Mbps. It works near full speed in other modes, but I need to use PPPoE.
New gateway is strong, but I still need more than one access point, which it does not support.
How configurable is Google WiFi, and is it a good performer with PPPoE?
