"No client associated" - Wireless Signal

WRT_Opener · February 20, 2023, 9:58pm

I'm trying to setup my router to provide WiFi from my ISP's router/modem. After I get this working, I'd like to set up an isolated guest network for added security. So far I've only followed this initual setup guide and then this WireGuard guide (starts at 5:25) for Proton VPN. At first, the wireless connection worked for just a few minutes but then on the mobile devices it started saying "no internet access" and LuCI says "No client associated" for the signal in the Wireless Overview tab (Ethernet connection works flawlessly though and with the VPN included).

I've already set my country code accordingly, tried stopping the VPN interface, factory resetting the router and setting it up accordingly with the two aforementioned video tutorials, and rebooting it countless times but nothing seems to have worked thus far. I saw this similar post but I'm not trying to do all the stuff this poster mentioned and I couldn't find the "Create bridged" button to test it out. I tried to post my system logs here but they seem to be over twice the post character limit. Any help is much appreciated!

I'm using -

Let's see your config files

Please copy the output of the following commands and post it here using the "Preformatted text </> " button:

Remember to redact passwords, MAC addresses and any public IP addresses you may have:

cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall

Where do I enter those commands? When I enter them in my computer's terminal, I get the following output:

[device@fedora ~]$ cat /etc/config/network
cat: /etc/config/network: No such file or directory

psherman · February 21, 2023, 1:15am

you need to ssh into your router first.
the username is root, password is whatever you set (or if you haven't set it, it'll just go right in

ssh root@<router.lan.ip.address>

Alright, here's the output. I believe I've redacted the sensitive details with "XXX". By the way, my VPN doesn't support IPV6 and therefore doesn't provide an IP address for it. I'm not sure if this could cause any issues.

Remove the bridge from the WAN... I'm pretty sure this is your main issue.

also note about the wan interface -- setting a DNS that (appears) to be available when the vpn is active means that it won't work properly any other time. You should change this to a public DNS server.

Remove the DNS related entries from here -- they don't do anything in WG config stanzas:

This doesn't do anything right now because Ecuador6 is not a network name... that's just a description in your wg config. The correct network name is vpnserver

mk24 · February 21, 2023, 1:52am

Since IPv6 is not supported upstream (through the VPN), set the lan dhcp so it will not advertise itself as an IPv6 capable router. Change ra and dhcpv6 to 'disabled'.

psherman · February 21, 2023, 1:57am

Another quick thing... it is not necessary to redact this information. It doesn't reveal anything sensitive or private since it is (or should be) an RFC1918 address.

WRT_Opener · February 21, 2023, 2:01am

@mk24 I believe this is already disabled, right?

mk24 · February 21, 2023, 2:06am

Go to Network-->Interfaces and edit the LAN. Click the DHCP Server tab then click the IPv6 Settings tab on the next line below it.

On the LAN.

WRT_Opener · February 21, 2023, 2:15am

How do I Remove the bridge from the WAN?

Also, Ecuador6 is what I named the VPN interface. I just entered vpnserver in my post because I thought that detail might've been sensitive.

psherman · February 21, 2023, 2:18am

I'm actually not sure how it got there in the first place... I'd remove it with either a text editor or the UCI commands.

names like that are typically not sensitive.

WRT_Opener · February 21, 2023, 2:21am

Do you know of a command to remove it? I'm not sure how I'd do so with a text editor.

mk24 · February 21, 2023, 2:23am

I think it would be:
uci del network.wan.bridge
uci commit network

That option should not exist in the LuCI of 22.03, so I also wonder how it got there.

WRT_Opener · February 21, 2023, 2:25am

I got this:

root@OpenWrt:~# client_loop: send disconnect: Broken pipe

mk24 · February 21, 2023, 2:26am

Can you reconnect?
