What type of devices are you using to test your wireless connection with?
Laptops? Smart Phone?
How old are the devices?
In order to take advantage of gigabit speeds you need a device that has wireless AC or AX. While AC has a max theoretical of in the gigabits speed, the practical speeds are much lower like 100-400 megabits. Wireless AX can is supposed to be much higher like a theoretical of 10gbs but ends up being something closer to 1.2gbs max and has a practical speed of closer to 700-900 mbs. This is all subject to network congestion, device capability, concurrent activity, distance from the device and other often intangible factors.
People come on these boards hoping for solutions but each situation is unique and therefore requires individual investigation. Sorry if this bursts any bubbles. I'm going through the same issues right now and I have decided I'm just going to hardwire my gaming computer to the router to get the best possible speed.
I'm interested in this discussion as I just 'upgraded' from the XB6 to the XB7 and it's definitely been disappointing so far. It keeps droping signals and some devices simply haven't connected, like multiple Alexa devices and iPhone / iPad. They connect, then drop off. I didn't have this issue with the XB6.
Do you know if any firmware update has fixed the horrendous Wifi coverage it had ( a known fault that they shipped with)? I got gig xfinity 3 month ago, and within 2 weeks , I had to put it in bridge mode and but a google nest wifi solutiopn. I was getting 900mbps intpo house , but ONLY 60 mbps from 1 FOOT away on 5 testing devices. It then droped to below 20 mbps one room away and no connection 2 rooms away. thx
I also noticed the gateway speed test was removed. I think this is a disgrace considering that's the only way to test the speed coming in to the house. I have a gigabit plan but not close to that speed on my hardwired connection to my computer using cat7 cables. Have had techs come out and they do nothing. Now I feel xfinity doesn't want us to know the incoming speed.
