I have had the deco P9 system now for about a week. Installation and set up went just fine. During the first five days after set up I was getting consistently in the 50 to 80mps range anywhere in the house WiFi via fast.com. I was getting 90-100 on my desktop through Ethernet cord. Now for the last couple days I'm getting 20-23 mps on any device via WiFi and still 90-100 on the desktop. I've tried when only one device is on wifi (mine) standing next to each deco device and no change at all. I've tried other devices, same speed. Why is my WiFi speed now dropped with my internet speed the same?
Also, my mane deco device (hooked to the modem via Ethernet) showing up on my list of devices hooked to my WiFi? That would be the last device (confirmed via serial number) of the three I would expect to see on the WiFi. I'd understand if one of the other two showed up because it was using one of the WiFi streams for the backhaul (although with the p9 that's supposed to happen through PowerLine). What's up w that?
