Wifi extremely slow compared to netgear speed test from router... how do I fix this?

[fenzinna]

Every now and then it peaks and runs a full 350mb/s but most of the time the devices(all -- laptop and mobile) are hitting 5mb/s or less. It's been like this since Sunday. It's not an Xfinity issue. I'm about to return this mesh system back.

What router do you have? 

Firmware on the router? 

what modem/gateway is it connected to? 

What wired speeds do you get? 

What speeds over 2.4ghz?

And over 5ghz?

What device/devices are you testing on? 

What site/app are you using to test speeds with?

it's the nighthawk mr80... the ac3600 wifi 6 mesh system.

irmware Version V1.1.6.6_3.1.93

surfboard 3186

I can't hook up to the ethernet in to a pc but the router's speed test says 350mb/12mb.

I can't test between the two but my speed test on both laptop and iphone swing from 330+ to under 5mb/s. No in between.

speedtest.net is the testing site for my mac

the mobile version is on my iphone.

If you're testing directly off the router (shut off the satellites) do you get the same speed?

If you can't fix things with this discussion, more detailed queries on your device are best pursued in the appropriate section

You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:

Nighthawk Mesh System - NETGEAR Communities

No need to go there unless this runs out of steam.
