cax80 xfinity slow speeds netgear needs to fix this
another cax80 not getting full speed from xfinity there is a problem here just had a guy out to check the wires from xfinity and everything is great and tried to talk to xfinity and they sent signals...
it's not the wifi the speeds I'm getting is 125Mbps the internal speed tester says 450Mbps when I pay for 1gig but I use wifi 6 on my Samsung s10 with the provided router from Xfinity and pull 800mbps they came out and said nothing is wrong with the wiring so it has to be Netgears problem with the software I use Xfinity speed tester and it says 125 Mbps so it's not Xfinity when their service works just fine over wireless with their router either it's how Netgear sets up their cable settings don't work with Comcast when it says it works with Comcast gig service

1. The built in speed test app rarely maxes out speeds. It uses speedtest and regularly chooses servers that are close but don't max out speeds. Its an issue netgear is aware of.
2. What devices is getting 125mbps? Is it on 2.4ghz or 5ghz?
3. Your samsung s10 is getting 800mbps over wireless? that's pretty impressive for wireless.
4. Do you have a hardwired device to test with? And what device is it? again, that's the key because wireless won't max it out and the built in testing isn't going to either.
5. Yes I do have xfinity. I can max out the gigabit link at 940(ish)mbps and my 2.5/5/10gbps link will max out 1150mbps. Thats on xfinity's speedtest site. And it does work fine with comcast.
- if you look at the included pictures I posted from Xfinity on my s10 I can pull 800mbps and no I don't have a laptop that can plug into the cax80. but with WiFi 6 you can almost pull gigabit on it but this the cax80 it says it's wifi 6 but it can't even do 100mbps my Xbox on it can pull 500mbps but that's because it's limited I will buy a ethernet adapter to see but it doesn't seem like that's the issue the tech support people said that it should be pulling the full gig to the routers interface for the speed test

So its supplying the expected speeds. and no I don't have a laptop that can plug into the cax80----Which is what's needed to actually see whats being supplied to the router. And not just a standard gigabit as that maxes out at 940mbps. . but with WiFi 6 you can almost pull gigabit on it----under optimal conditions over 5ghz. Again, optimal. Without interference, other devices using bandwidth, and a device that is capable of maxing it out. but this the cax80 it says it's wifi 6 but it can't even do 100mbps my Xbox On what test server? I've never seen xbox use a proper speedtest server for testing. And is it over 2.4ghz or 5ghz? Thats an expected speed over 2.4ghz. on it can pull 500mbps but that's because it's limited I will buy a ethernet adapter Which might not max it out either as some cheaper adapters won't to see but it doesn't seem like that's the issue the tech support people-----What tech support people? the netgear built in speedtest server won't max it out. said that it should be pulling the full gig to the routers interface for the speed test- no it's not supplying the speeds on wifi 6 5ghz it's doing 150mbps the one that does do the correct speeds is the Xfinity supplied one the xb7 with WiFi 6 you are not understanding it just doesn't work for me even tho the other wifi 6 router from Xfinity does do the speed but with my s10 on the Netgear one it does only 25mbps on 5ghz that's a problem
- and the device that's pulling the 125 is my laptop with WiFi 6 built in
- I have a a brand new laptop and on the wired connection I'm seeing the exact same thing the poster did.
When i switch back to the adris, i get 1.2 gig on the exact same devices.
It seems like this is just s defective device, but netgear sorry are useless. I would but a carrier pigeon before i would give Netgear another dime
- also do you get error codes like this?
