Can't figure out WiFi

weider · October 17, 2024, 8:05am

I've installed OpenWRT on Proxmox VM. LAN works fine, everything works as expected. But WiFi just doesn't. I have no idea what's wrong. It's using the AX200.

The AP shows up and I can connect to it, but that's about it. Nothing is going through, not DHCP not even ping. I now tried making a bridge but even that didn't help. Before I tried with the bridge I just set the network in the Access Point to "lan"

network

config interface 'loopback'
	option device 'lo'
	option proto 'static'
	option ipaddr '127.0.0.1'
	option netmask '255.0.0.0'

    option netmask '255.255.255.0'
    list ifname 'eth0'
    list ifname 'wifinet0'  # Add wifinet0 to bridge the wireless interface
    list dns '192.168.0.1'

Remove this line. It is added from g/wireless

That was super fast. And annoyingly simple. I swear chatGPT(who recommended the config you fixed) is making me (and probably someone else) lazy and stupid.

As per brada4 beating me to it.....

Shouldn't need to add the wireless adapter to the bridge.
Having the config under wifi-iface as network 'lan' should be fine?
It then gets added to bridge when wireless starts.

Why AX200? Assuming intel client card running in AP mode? I don't have experience with newer intel cards in AP mode.....

It's the minisforum S100, works on 20v usbc, so I can power it in the car and run some VMs on it. Only thing I have to work with right now. Waiting for a RT3572 dongle.

brada4 · October 17, 2024, 8:13am

Stay out of it, it only messes stuff up. Worst it throws weird constants across the board, yours is something new though

brada4 · October 17, 2024, 8:14am

If you can get mt76 card, though full separate (dumb) AP may turn out cheaper.

weider · October 17, 2024, 8:21am

You mean compared to the whole setup?

It's a bit complicated, I'm running KASM on one of the VMs, so I need the Minisforum S100 for that. I initially had the car connect directly to a home server but as KASM is live transmit I had issues when the car was moving. So I decided to put the KASM server in the car and everything else it does (youtube/plex) will buffer on it.

Just for clarity, the passenger uses it, not the driver.

I'm not familiar with mt76, but the dongle I found is like 20€, was just difficult to find. And performance is not a big requirement, anything above 10-15 Mbps will be enough

EDIT: also, just for more context. I initially wanted to use KASM for a better browser experience, tabs, auto login, history management and so on. But then I quickly realized video works while driving. So I just had to experiment. Basically I have a Proxmox server in the car, running at 9w of a 20v cigarette plug charger.

welll...

evs · October 17, 2024, 8:23am

It says both ax200/ax201. If it's ax201 replacing the built in card becomes no go? CNVio2..... not pcie =(

But yeah i think the reason why mt76 is suggested is due to software support and better AP mode options?

brada4 · October 17, 2024, 8:25am

Roughly it supports most features, ath 9 10 are ok too.

weider · October 17, 2024, 12:59pm

It's the AX200.
Works great now though, everything as it's supposed to be

Phone tethering through cable and then through Wi-Fi access for the car. In between I can modify the traffic as I see fit with OpenWRT.

Thanks for the help
