Internetspeed slows down to like 5% of my normal speed

Community Member

After having used my NEST PRO for a while now it has started dropping my internet speed on the WIFI side for some reason.
I usually have 480-500 mbit download when Im testing my speed via my wifi on my phone while close to the "main" Nest Wifi Pro router. And when I test my speed while at my computer that is connected via Ethernet to the node that is furtherst away from the main node I land at around 300 speed.
Then suddenly my speed drops to something like 10 download 1 upload and I have big problems connecting to certain sites etc.
If I enter Google Home and do a speed thest and mesh test nothing seems wrong. Speed on the main router is still 480/100 so its not an ISP problem. 
My only solution I have found is to do a software reboot on the entire system. But this is not something I would like to have to do every week just cause my internet decides to dip in speed for no reason.
Its clearly a firmware issue on the Nest side and I sure hope there is some solution to this. Some setting I have missed etc. 
Softwareversion on the node is: 1.63.355999

Hi folks,


That certainly isn’t the experience we want you to have and apologies for the delay. A few questions: are you using a modem/router combo from your Internet Service Provider (ISP)? Also, do you have any paused devices?


Give these steps a try:


  1. If you're using a modem/router combo, set that to bridge mode to avoid double NAT issues.
  2. Make sure that there is minimal to no interference (concrete, bulletproof glass, metal, mirror, etc.) and the points are no more than two rooms apart.
  3. Remove any special characters in your network name and password.
  4. Turn off IPv6:
    1. Open the Google Home app Google Home app.
    2. Tap the Wi-Fi coin  and then Settings Settings. 
    3. Scroll down and tap Advanced networking.
    4. Scroll down to IPv6.
    5. Toggle the switch off Toggle button off.
  5. Change your DNS server into on the primary and on the secondary server. Hit the save/ floppy disk icon on the upper right.
  6. Unplug the power from your Google Wifi devices for 2 minutes.
  7. If the issue persists, try factory resetting your network. Take note that this will delete all network data.


You may skip any step that you’ve done already.
