lesmikesell the free deal may include both Pods, but I would ensure I got both of them in that first order, just in case.
These Gen 2 Pods, errr, they changed the name, WiFi Extenders, have the capability of using a direct Ethernet connection with an XB8, and can use that for Ethernet backhaul, which you’ll see significantly faster throughput as result. So if you can run a high quality Cat6 Ethernet cable to those dead spots, I’d go for it. I’ve seen speed tests on a device connected via WiFi to this WiFi Extender (with Ethernet backhaul) pull download speeds of around 600Mbps, consistently. But yes, the official documentation shows a max of 500Mbps. These devices are actually manufactured by Plume, and while Xfinity has designed them for their network, you can get some valuable info about them from the Plume website.
