Google Nest Thermostat unable to connect

RouterOS Wireless Networking
1

I have a L009UiGS-2HaxD using RouterOS v7.14.2 with the following WiFi configuration:

/interface wifi set [ find default-name=wifi1 ] \
    channel.band=2ghz-n \
    country=canada \
    .skip-dfs-channels=10min-cac \
    .width=20/40mhz \
    configuration.mode=ap \
    .ssid="Foxes by the Lakes" \
    disabled=no \
    security.passphrase="some super secret password" \
    security.authentication-types=wpa2-psk,wpa3-psk

We have no problem connecting our phones, laptops, smart TV, dishwasher, etc. However, when trying to connect the Google Nest thermostat it sees the network, spins for a while, then fails to connect. Also, when I run a hotspot from my Andriod phone, the thermostat connects to the network without any issue.

Google’s FAQ states the following:

It’s very rare for router settings to be the cause of this problem, but here are the only settings you need to check. Refer to your router’s manual for instructions on how to do the following:

  • Turn on your router’s 2.4GHz Wi-Fi signal.
  • Enable 802.11 b/g/n if you have an 802.11 ac router.
  • Set your Wi-Fi router’s DHCP lease time to at least 2 hours.
  • Turn on your router’s Power Save Mode (PSM), if you have a Nest thermostat.

My questions for anyone who is able to help:

  1. Does this WiFi configuration look at all problematic?
  2. How do I go about tracing the packets to try and troubleshoot exactly where things are breaking down?

Thanks so much for the support!

Try disable wpa3

That fixed it :tada::tada::tada:


Thank you so much :grinning_face_with_smiling_eyes:

I’m glad it worked. Try also to set the band to AX: your laptop will be probably faster and the setting is backward compatibile with N

Thanks for the tip! :blush:

Unfortunately AX doesn’t seem to be compatible with my TP-Link HS105 Smart switches :pensive_face:

Is it possible to use both N and AX simultaneously?
Would I need 2 different SSID’s?

That is unexpected. As far as I know, it is not possible to have different bands on the same radio. Are you sure it is matter of band and not of channel? Can you see what channel the router chooses using the two bands?

7

Ahh I see.

The router chose:

  • 2432/n/eC when set to the 2GHz N band
  • 2417/ax/Ce when set to the 2GHz AX band

And actually you’re right, they ARE still working :tada::grinning_face_with_smiling_eyes:

The reason I thought they weren’t is because their signal is not showing up on the Quick Set Local Clients list

The L009UiGS-2HaxD is still pretty new though so perhaps that’ll get fixed in a future firmware update

:folded_hands: Mikrotik plz fix :folded_hands:… and thank you for the great products!1!!

Probably, it is better to go to WiFi > registration to check the list of clients. AFAIK, the quick set screen should be used only once for the initial configuration, hence I don’t think mikrotik investested/will invest much effort in fixing that.
In any case, the forum is not read by the devs, so you should send a support request for that.

Aww, I hope they do, I love that graphical Signal Strength graph/column. Or maybe add that along with “Name” to the WiFi registration tab - that’d be SO sweet!:ok_hand:

However, I just found out why those HS105 weren’t showing up on that list - it’s because they all chose the garage AP instead :skull_and_crossbones:

Thanks so much for all these tips @ips!! I’ll send that suggestion to the dev’s
