rax40 bridged slow wifi

[network_noob]

I have been noticing my wifi slow down recently and I can't seem to figure out why. I have my centrylinkC1100T set up bridged with an Ax4 RAX40 ax3000 router. I am getting only half of the speed that I pay for. I pay for 100mbps and only get 60mbps at most even 5ft from the router. When I run the speed test that is built in the nighthawk app I get 97mbps but when I run a speed test on any other device I only get half of that. Why could this be?

are you connecting to 2.4ghz or 5ghz?

2.4ghz is much much slower than 5ghz and the speeds you're getting would be understandable if you're on the 2.4ghz. 

For faster speeds, make sure your on the 5ghz band.

On 2.4ghz I get 50mbps, On 5ghz get 70mbps when I run a speed test 5ft from router, is this normal? Or should it be more like 90mbps?

if you run the centurylink modem/router in router mode and put the rax in access point mode, what speeds do you get then? 

it wouldn't be the first time a ISP supplied modem/router didn't have a proper bridge mode

[network_noob]

Sorry I'm a noob at this , but I currently have my modem/router from centrylink in transparent bridge mode and all I did on my nighthawk router was set up the PPPOE. I will try AP mode.

If you put the netgear in AP mode, you'll need the disable bridge mode on the centurylink

I reset my modem/router and connected my nighawk router to it. Then I put the nighthawk router in AP mode but now it just tells me that there's no internet connection. What steps am I missing?

[plemans]

If you log intot the isp supplied device, is it in router mode?

Is it broadcasting wifi and can you connect to it and browe?

[network_noob]

Yes

[plemans]

how do you have the rax connected to it? 

lan port from isp router  to wan port on RAX? 

And the rax is in access point mode?

[network_noob]

Yes exaclty like that

[plemans]

If you log into the ISP supplied router, it should be giving the RAX an IP address since its controlling dhcp. Is it assigning an IP address? 

[network_noob]

Yes it is I think but the WiFi very slow and unstable
