I'm new to OpenWRT. And I've started using it because I got myself an GL-iNet travel router which wasn't seeing networks that were broadcasting above channel 11. There were no settings to change it in the default GL-iNet firmware, which is net verry useful for a travel router...
So, I'm actually having the GL-AR300M16, and flashed it with OpenWRT today. I've flashed using an UTP to my laptop and to configure the basics so far. Apparently WIFI was off on default so I needed to turn it on over UTP.
The main reason getting over to OpenWRT is because the router couldn't find networks above channel 11 (I think because those GL-iNet routers are standard set to USA). Now with OpenWRT installed I was able to find my own router (channel 12) when changing the country to NL in wireless settings.
So far so good.
All the settings kept original so far, besides the host name, the SSID name, the wireless password and the Luci admin password. So nothing really special.
But I can see the wireless network SSID with my telephone and I'm able to connect and login to the admin page. Same goes for another phone.
But strangely enough I can't see the wireless network SSID from my laptop.
I've scrolled through the settings of Luci a bit. But I can't see any strange things so far.
So long story short:
Wireless radio is turned on
2 smartphones can see the wireless network
But my (windows 11) laptop can't see the wireless network.
I'm actually thinking I'm missing something here in the settings. However didn't tried to connect wireless from my laptop to the router when the original firmware was installed, so can't tell if this was working back then.
If you're using channels above 11 in the 2.4G band, your laptop's wifi radio may actually be the limitation. It is entirely possible that the laptop's wifi hardware my not be capable/tuned/firmware-allowed for those channels.
My "home router" is broadcasting at channel 12. And my laptop and all other devices I have see this network and are able to connect to it.
The GL-iNet router, which I would like to use as a travel router, could not see channels above channel 11. Seemed to be a regional setting.
All my devices can see and connect to standard home network (channel 12).
2 tested devices (mobile phones) can see the newly broadcasted network from the travel router (channel 1).
my laptop can see the network of the home router (channel 12) but can't see the network of the travel router (channel 1). (the laptop also finds the neighbors network which is broadcasting on 12 or 13, so the laptop should not be the problem here regarding to the channels above channel 11).
So the problem with channel 12 was actually the GL-iNet firmware, which was restricting seeing networks all above channel 11. This problem is solved now by flashing OpenWRT.
It seems my laptop is seeing all kind of different networks here in the street. It's a whole list and when I check a similar list with a network scan app on my phone, then it tells me that all those network vary from channel 1 to channel 13.
I was just counting the networks I'm seeing with my laptop (over 40, varying from all kind of channels) while typing this, and then I saw the "travel router" too for a while. I've made an extra channel to test with (1 on ch1 and the other on ch6).
And I saw them both for a short while. But they disappeared again now. Strange, because the router is near and both my phones say the signal is pretty strong.
Well it seems that both of the broadcasted networks schare the same channel, so when changing the channel in SSID-1, SSID-2 gets the same broadcasting channel. So both of them turned to channel 6,
But most importantly, when I change the broadcasting channel of the travel router, then both SSID's are temporarily visible between the list of networks my laptop sees. But just for maybe 1 to 3 min.
Maybe I'm misunderstanding you here. But that's my config. I put to use channel 6, it was standard set to ch1.
Actually tried a few different channels, to look if it mad any difference. Left everything besides that and SSID/encryption option to standard values.
Couldn't find this command line, so I've backed up my config in system and took this from the /config/wireless folder of the backup.
