I work from home and am on Microsoft Team calls everyday for hours and hours. We also stream Netflix and other streaming channels in the evening. I live in a condo with an other units in the housing.

Using Speedtest it shows huge latency (500-1000ms) every so often and then I would power cycle the modem and router and all is well again where latency drops down to 15-20ms. I have Xfinity with 200 MBps speeds.

I used to have an Arris SB6141 and bought an Arris S33 hoping to fix the issue but still having issues. I have a Google WiFi as my router connected to my modem with 2 other pucks from 2016 or the one before they were called Google Nest/wifi/home. The pucks are located on my top floor, a side bedroom and one in the basement.

What can I do to prevent myself from having to power cycle my modem literally everyday? Is there a better cost effective router that will reduce latency all together? It seems resetting the modem fixes the issue but that’s annoying to do everyday.
