Nest Thermostat Router settings

[CapVincenzo]

My Nest thermostat kept losing power. Turns out its the WiFi that keeps killing the charge. I know this because my brother in law is an HVAC tech and he checked the system and even rewired it to make sure it is getting power. But it still kept dying. So when I called Nest, they said turn off the WiFi. I did and the thermostat never last power. So they provided me with a set of settings, but I don't know if we are allowed to use them or even how to set them to this.

Here are the settings suggested:

Summary of recommended settings

Here are the most important recommended Wi-Fi network and router settings for use with Nest products. For more details, refer to the sections below.

• 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.
• Enable IPv6, if you have a Nest Protect.
• On your Wi-Fi router, turn on multicast, if you're adding additional Nest devices.

Can someone help me accomplish this task?

Which version of Nest Thermostat do you? I have never had a battery issue per se since I installed it 18 months ago. The Nest battery charges when power it is continuously provided from the furnace. If there is no continuous power, the battery will drain. The furnace does not have to be operational but the power must remain on. It there is no power, the Nest Thermostat will continue to work until the battery is fully discharged.

I have a Nest thermostat 3.6, that controls my furnace. When not in use to control Heat or A/C it will not drain the battery even when turned off as long as continuous power is coming from your furnace. My modem is a Bell Giga Hub. It is set up with auto assign DHCP. Most of the settings you mention are presets in the modem. I did not need to change anything. 
If for some reason, you need to change modem settings, you can do this by logging in to your modem using a web browser: 192.168.2.1

Once logged in, you need to go to Advanced tools & settings. From there you can make some of the changes you mentioned earlier in Networking. Just be careful on what changes you make…. You could take your modem down.

If I can be of further assistance, please reach out again. Take care.
