Very slow download and upload speeds

Recently I noticed my wifi speeds have been extremely limited and I think it has something to do with the Nest wifi router. 

 

my setup is Nighthawk Cax80 cable modem (modem mode), Google Nest Wifi router and 2 Nest wifi access points. The Nighthawk is set to modem mode and the nest router is wired into the modem within 2 feet of each other. The 2 access points are within a rooms distance of the of the router. I pay for 400mbps per month and with a speed test of the wired router via the Google Home app, I receive 400+ mbps download consistently. However, when I test the wifi its drops to the kbps. I talked to google support and they had me restart modem, router and points and it worked briefly but it went back to very low speeds. Google support suggested I contact Comcast. Comcast sent a tech out and he said the isp is working properly, which I figured bc of the speeds to the router were more than I pay for. I want to trouble shoot my current setup to see if its possible before I start from scratch. 

My next step is to factory reset cable modem, router and access points and redo the setup as follows: Nighthawk Cax80 as modem router, Nest wifi router as a wired access point and add the other nest wifi access points. 

Please help!!!

I had to call support and it fixed the issue by changing the primary and secondary DNS servers to 8.8.8.8 and 8.8.4.4 ,respectively. Additionally, I repositioned my points to optimize connection between them. After the fix, for the past 48 hours my speeds have been more than what I pay for.

I would make sure the modem is set to modem only and disable the router feature. Also, I would expect to get the paid speed via Wifi however you should get close via wired via Nest points if available

I would try Google and opendns values as option. 

See if  mesh test says excellent.
