Erm... unless you have the disposable income for it I’d say it’s not worth it. Wired into my Mac it’s amazing, 1.1GB constantly now.
I thought it was a 900Mbps service not over a gig. How are you getting over a gig on a speedtest? Normal gigabit LAN port will top out at around 930Mbps.
What speedtest do you use of interest? If "speedtest", are you getting this with multiple servers?
where it struggles is on SKY Q and PS4 where they are wired with home plugs. PS4 I’m getting 120mb down but I think that maybe because Sony are currently throttling. SKY the downloads are painfully slow. Half an hour to download a portion of a TV show before I can start watching. Think I need to go back and reload at these two devices.
Powerlines are not suitable in a network like yours unless you are happy with the limitations, 120Mbps could well be you powerline real max throughput. Most testing websites have even the 1200 and 2000 advertised ones do not get much past 150Mbps, possibly 200Mbps with a favourable wind. Is that the PS4 reported speed or average time in downloading stuff? I generally get very quick downloads certainly more than that speed.
I am on Virgin's Gig service am also sometimes have issues with slow Sky Q downloads. I am hardwired for most stuff including Sky Q and it doesn't get particularly good download speed at the best of the time.
We are also not upgrading the Hub from the original to Hub2, spoke with the lady on the call and mentioned there was no different between them, they will both give the high speeds. The good thing about the first Hub is you can choose 2.4 or 5ghz
2.4GHz won't normally get much past 150Mbps if you are in the same room, to go any faster you definitely need AC. Unfortunately, most of the call centre staff don't have the level of training or knowledge required to really advise properly.
If you have 50 clients in your house on one WiFi router/access point, then personally I would want to ensure that my internal network could handle that properly first. I would want to install multiple access points, hardwired back to the router\switch as well as hardwire equipment that can be. That way you can better spread the load around your network and better make use of the improved bandwidth. Otherwise, you end up with a bottleneck for your entire network particularly as a lot of devices these days talk to each other and that is all in contention with your actual requests to the Internet if done through the same WiFi point.
As a general statement, I think we are really getting into diminishing returns increasing from 300 > 500 > 1Gbps etc. We are also highlighting inadequacies in our internal home networks (plus at the other end of the Internet connection e.g. slow servers). For me, the upgrade was to get a better upload speed on VM its only 50Mbps which is still poor compared to fibre especially given DOCSIS 3.1 can accommodate well over the Gig. Probably haven't really noticed the download speeds much beyond speed tests and Steam downloads.
The question I would ask is what problem are you trying to solve in upgrading your speed. It is not going to make Netflix any better, sure you can have more streams but how many do you need. For an average family home with 4 to 5 people in all streaming UHD is only 125Mbps
A lot of business with more staff don't have much more.
If you can't answer the question (or it is to upgrade your hub) then save your money
