[SOLVED] 2025 R1S (Gen2) does not see WiFi 5GHz mesh node

[srg]

Just got the car, and the first thing is ... can't connect to home WiFi. Great experience... in addition to a broken wireless charging pad in the center console.
In the WiFi settings, I see all possible networks but not the 5GHz, specifically looking for the mesh node since the base router is quite far and the signal is too weak.

My setup.
Router: ASUS GT-AXE16000
Nodes: ASUS 2x ZenWiFi Pro ET12
all of them are tri-band (2.4GHz, 5GHz, 6GHz)
5GHz SSID: three letters like "AnB"
5GHz Security: WPA2-PSK-CCMP
2.5GHz SSID: "AnB-2.4"
2.4GHz Security: WPA2-PSK-CCMP
6GHz SSID: "AnB-6"
6GHz Security: WPA3

I have no issue with connecting to wifi mesh on any other device, and my phone gets 200+ MBps (5GHz) from inside the parked car.
I can connect to 2.4GHz from the car, but it's already too "crowded" due to security cameras.

I don't know if it's a problem with Rivian software or perhaps hardware.
Has anyone had a similar issue?

---------------------------------
UPDATE (9/13/2024):
Rivian support told me on the phone that the car supports 2.4GHz only. This is not true.
UPDATE (9/24/2024):
the car has relatively weak antennae located somewhere in the back (the shark fin?). I parked my car in reverse (instead of head in) and immediately got the 5Ghz connection.
To add, my phone can get the connection even if located behind the car so the all the layers of metal and other material obstruct the path.

I don't believe this was changed in Gen2 (someone may correct me) but Gen 1 was 2.4 only.

I can see the 5 GHz signal on my Gen2 but the WiFi range is rather weak on my R1S. Where my phone might have a decent signal in the driveway the R1S struggles.

Do you have a wifi mesh setup?

Is there an option to type in the SSD manually?

5GHz is notoriously bad at travelling through walls due to the high frequencies used. Assuming the Gen2 actually has 5GHz support, my guess is the signal is too weak.

yes, and it does not connect

Good guess, but as I mentioned the signal is very strong and I get 200Mbps+ on my phone while sitting in the car.

I dunno, set up a 2.4GHz node. 5GHz is pretty much useless for IOT devices anyway.

I do and it's a dual band. Rivian would had to change the wifi for G2 (I have G1) because it only connects to 2.4, not 5 on my mesh home network.

I have a node/satellite in a garage since everything from sprinkler to water circulator to garage door to outdoor cameras are on the network.

Gen 1 definitely supports 5GHz. I'm sitting in my driveway and connected to mine now. It does tend to "prefer" the longer range of 2.4GHz (connects first since it sees it from further away), but I tend to prefer the higher speed and less cluttered network of 5GHz.

Best suggestion I have is give your networks different names. This is easy on most routers. Then it's easy to tell for yourself and control which you connect to. ?

My 2023 R1S supports 5GHz - it is connected to the 5 GHz right now.

The wall charger on the other hand does seem to be 2.4GHz only.

Fully different devices, but that must be what I was remembering I set up a network specifically for.
Truck has been at the SC for a minute and wall unit has been offline.

2.4 is too crowded? I only use 5ghz for things in the house that I know will have good signal. Anything outside gets 2.4. I have over 60 devices on my ASUS mesh network, including a bunch of cameras. Just leave it on 2.4, it will be fine.

Don’t know if this will help. Some router/ modems have an IOT network that can be enabled. Stands for Internet of Things. I have fios.
I have had some devices that will not connect to my mesh network , but will connect to the IOT network off the original router/modem.
