Google Nest router upload speed drops over time, but download speed has been consistently good.

[SN311]

Hello, I just got the Google nest wifi router about 10 days ago.   Whenever I run speed test, doesn't matter which site, but I mostly use Bell's, the upload speed would be good, a little over 10 Mbps per my internet plan.   However, if I do it a few times more, the upload speed would drop, so by the 4th of 5 th time it would be down to 6 or even 5 Mbps.

Download speed would remain good regardless of how many times I run speed test.    Is there anything I can do, or should I get an exchange when I am still within the 14 day window?    I have already try the power cycling the modem, the router, and restart network using Google home.   The upload speed would always go back to normal right after I did a "restart network", but as soon as I ran speed test a few times, upload speed would drop again.    

Thank you

Have you tried disabling all preferred activities? Worth a try.

I haven't tried that yet but will, if I have to.   I did use the chat help and the agent told me it was because double Nat that slowed things down.   She told me to try using bridge mode on my Bell HH3000 that is a modem router combo, unfortunately that modem does not support bridge mode and their tech support did not know how I can use DMZ and disable DHCP alternative.

Out of frustration, I decided to mess around with the HH3000's settings and the thing locked up, the only way I could try was to factory reset.    After that, the upload slowing down issue went away.   It seemed to have return yesterday so I tried the same trick but on the first two factory reset, problem remained though less severe in the sense that even after doing speed test several times in a roll, upload speed would only slow down to about 6 Mbps at the most.    I then did one more reset, and it has been good since, with download speed consistently = or > 10 Mbps, topping at 10.7 Mbps in areas where my mobile phone is connected to the wifi points via mesh.    The top speed for that, if connected to the Nest router's wifi is 11 Mbps.    I am going to leave it alone for a few days, if the issue return then I'll try your suggestion.

Thank you.

Not at the moment because the last modem/router factory reset seemed to have fixed it, but only time can tell if the fix would hold, because I don't know how such a reset (details in my response post to olavrb) could have fixed the issue.    Thank you for following up, appreciated.

Will report back in a few days, if it still works then I think it will continue to work.
