Numerous DHCP requests Tesla Powerwall 3
Good morning, I have a Netgear Orbi 753 router and two satellites connected to Wireless Backhaul, satellite one connected to the router and satellite two connected to satellite one. I have a Tesla Po...

The powerwall wifi client is choosing to switch.
Options are to
- set up a 2.4 ghz-only IoT network and switch the powerwall to that network.
- move one of the satellites closer to the powerwall, in hopes of getting a better 5 ghz connection.

Hi, thanks for your reply. I can't activate the IoT network, and I can't move the satellites closer together because they're placed in specific spots to cover the house. Why does Orbi sometimes use 20MHz and sometimes 40MHz in 2.4GHz? Thanks.

Sounds like the device is ping ponging around and can't get locked in to the closer or one particular signal. Saw this on my 850 series years ago.
What FW is currently loaded on the RBS and RBR?
What channels are you using?
20/40Mhz channel co-existence is for neighboring wifi signals that you maybe around on 2.4Ghz. Long time policy. You can force 40Mhz only on 2.4Ghz.
Distance in between the RBR and the RBS and each other? in Feet.

Hi, thanks for your reply. My router and satellites are running version 4.6.9.11_2.3.5. I'm not updating because the system works fine for months, so to speak. I only have to restart it a few times. The 2.4GHz Wi-Fi has the 20/40MHz option enabled, and I've never disabled it. Isn't there a way to use only 20MHz? I don't know exactly how far apart the satellites are. My router is in the study on the first floor, the first satellite is on the middle floor, and the second satellite is in the basement. When I restart, the two satellites always have the blue LED. I read that you had a similar problem. How did you solve it? Thanks.

Why is that?

It's a "good neighbor" policy required by the WiFi Alliance (that certifies wifi products). If the router detects another overlapping access point nearby, both systems scale back to 20 MHz.
If you log into the web admin ui, then you can select the "Advanced Tab", and then "Advanced Setup". The Wireless Settings menu in that section should include a checkbox for "enable 20/40 MHz coexistence". You can turn that off if you want to disable that policy.
To be clear, the powerwall (or other wifi clients) can still choose to connect at 20 MHz if you do this. The powerwall doesn't use much bandwidth, and the narrower channel can reduce interference and increase range.
FWIW, I doubt that is the problem. It is more likely that the 5 Ghz band isn't delivering a solid connection at the powerwall. That would result in the powerwall switching back and forth.
If the powerwall monitoring is working ok, then you could just leave well enough alone.

Yes, I always see the Powerwall online and I always see the monitoring
