mesh poor connection

[BellenKurt]

Hello

Since a few days i have constant problems that the mesh setup is giving poor connection on all access points. It worked without a problem for several years with great performance and coverage but since 2-3 days ago it started to give issues. I already tried the following items without improvement, so please advice is you have more ideas

- powered all of and left off for 2 hours then powered back on again on also a different network port 

- placed all access points in the same room with the router 

- switched the access points from their original location 

- factory reset of all access points and the router

Strange thing is when i just leave the router connected the wifi of the routes is great, and when i test the speed of the router to internet it is also great. Can someone help me with this. I also created a case with google support but still no answer from them

i also disabled ipv6 + changed dns to 8.8.8.8 + 8.8.4.4 but also no improvements

I am on the same boat, issue started about a week ago. Everything was working great before, nothing has been moved. 

mesh connection went from great to weak, even when moving the points (2 of them) right next to the router. 

people seem to be complaining about this same exact issue since late 2020....

Hello folks,

@BellenKurt, thanks for posting. I'm sorry to hear you're having this issue. You mentioned that you are already in contact with our support team. Can I have the case ID number of your interaction so I can take a look and check for you?
@zlh265, that's not the experience we'd like you to have. What troubleshooting steps have you tried so far?

Regards,

hello

i tried already all of these

- disabled wifi of other router

- put port in dmz

- configured in bridge mode

- created new home environment

- changed dns settings

- placed aps in same room at 2m distance

nothing helps, but i see on forums several persons with now the exact same issue that started happening also with them from last week. looks more a generic issue to me (firmware)

[BellenKurt]

my case nr with google is 5-2630000033732

they just replied me with again the same troubeshooting as above and i already tried all of them without result

i heard from 3 users so far with exact same issue since last week so looks more like update gone wrong?

I think I finally resolved my problem with poor mesh and poor wifi connectivity. I am posting my experience in case this helps the next person.

So I have done all of the above scripted standard troubleshooting, factory reset, changing DNS, turning on/off perfer activities etc etc.. all of which did not help.

Then I started unplugging my devices one at a time. Come to find out, one of my IP cameras which I have recently messed with by turning on "multicast" ended up causing issues.

I was able to replicate this by enabling and disabling  multicast, where when multicast was turned on, my mesh connectivity would drop to weak connection, and as soon as multicast was turned off, mesh connectivity would revert back to good or great.

despite mesh connectivity now showing great, my devices would still constantly drop off wifi with very inconsistent speed.

I have 2 switches for ip cameras as well as few other wired devices in the home. Because my switches were not properly setup, had all default settings including the LAN ip to their landing pages, and as well as my main nest router's LAN all set to the same IP 192.168.0.1...

This i guess ended up causing some sort of routing issues for the whole nest wifi system.

once I corrected the LAN ip for both of my switches. All of my issues went away. No more dropping off wifi. All my devices are now staying connected.

Again, just sharing my experience and my troubleshooting thought process. having poor wifi experience is very frustrating.

Hello 

i checked if i could find these settings somewhere but cannot disable it anywhere. Only camera's (or other network equipment) i have are google nest devices; and there i do not see the option to disable this

[AbigailF]

Hey BellenKurt,
 

There is currently no setting in your Google Home or Nest app to disable ‘Multicast’, so @zlh265’s troubleshooting step won’t work for your issue. I checked your case again and saw that our support team is still working on your case. Rest assured that you’ll get an update from them shortly.

if you have any hard wire devices connected to the nest wifi system somehow, try disconnecting/connecting one device at a time until your mesh connectivity goes from great to poor.

that's how I isolated my issue to one of my ip cameras. For me it just happened to be the one camera that I recently enabled multicast. It's an IP camera setting may only pertain to my specific camera, multicast allows streaming both the video and audio feed at the same time.
