Drop of WiFi speed on Google WiFi (model 3104) - associated with IPv6

[DavidA1]

Previously posted but issue was closed. "I have Google Wifi model 1304 (not Nest), and I'm getting the same symptoms. In my case I have 4 access points (one Cat 5-connected to the modem and the other three around the house). Software version 14150.376.32. IPV6 is off.  I can restore high speed occasionally if I reboot the Google system and then I see 800 Mbps or so, but very soon after than (less than an hour for sure) it goes back to 60-90 Mbps. "

I've seen many posts on this topic and unfortunately I can't append to them since they are usually closed when no resolution is achieved. My new observation: I can sometimes temporarily restore service by toggling IPv6 from off to on to off within the Google Home app. My speed as tested by the Google Home app goes from around 90 Mbps to near the max- about 800-900 Mbps. However, it doesn't always work, and it ALWAYS returns to 90 Mbps after a short time, typically less than a few minutes but sometimes maybe an hour. Something is CLEARLY wrong with the IPv6 setting within the firmware. I would strong hesitate to replace this (admittedly) somewhat old system with a Nest WiFi at this point since I've seen similar issues reported for that product as well. 

Any possibility of a resolution of this problem? I am not the only one dealing with this issue.

Hi DavidA1,

Thanks for posting — let's see what's going on. 
 

A few questions: are you using a modem/router combo from your Internet Service Provider (ISP)? How many devices are dropping from the network? Also, do you have any paused devices? 
 

Give these steps a try:
 

• If you're using a modem/router combo, set that to bridge mode to avoid double NAT issues.
• 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.
• Remove any special characters in your network name and password.
• Change your DNS server into 8.8.8.8 on the primary and 8.8.4.4 on the secondary server. Hit the save/ floppy disk icon on the upper right.
• Unplug the power from your Google Wifi devices for 2 minutes. You can skip this part if you’ve done it already.
• If the issue persists, try factory resetting your network. Take note that this will delete all network data.
   

Let us know how it goes.
 

Best,
Abi

I've tred all of the steps except for factory reset. I will do that in the next few days.

OK - I've tried all of the suggestions, including factory resetting our Google WiFi. It's still not working properly. Immediately after reset I observed up and down speeds of nearly 1000 Mbps- which matches what our Verizon Quantum modem provides. (While this is happening I've also confirmed that the modem is working consistently at the 1 Gpbs rate). After about 10 minutes it relapsed to about 90 up and down. Again, toggling IPv6 temporarily restores the network speed but it doesn't last more than a few minutes at best, and is not guaranteed to work every time. 

I don't feel like I'm the only one suffering with this issue judging from comments I've read online. Any suggestions or fixes to offer? I've got, again for the record, 4 Google model 1304 WiFi modules and a Verizon Quantum modem (router disabled).
