[Solved] My SSID is Not Displayed

Hello,

Recently I changed my internet service provider for my home wifi. I got a new SSID. I can connect to this SSID from my other devices like android mobile phone, laptops. But from this Dell laptop, model Vostro 1540, this new SSID is not displayed. It displays other's SSID's from nearer locaions. But not my own SSID. I connect to the router through cable to post this message. Please help me setting up wifi connection. Here are some information about my laptop and network.

Re: [Solved] My SSID is Not Displayed

You'll probably want to go into more detail on how you are using these two.

iwd.service                              | multi-user.target.wants
NetworkManager.service                   | multi-user.target.wants

As a general rule you don't want two independent network services vying for the same network interfaces.

But perhaps you are doing something like this...
https://wiki.archlinux.org/title/Networ … Fi_backend

In any event, you could use IWDs control knobs (iwctl) to do a manual site survey.

No, iwd.service would not be enabled then.

That being said: disabling NM + dhcpcd and getting a manual scan result from iwd will perhaps tell us more.

I disabled NM + dhcpcd. Rebooted and did a manual scan using iwctl. But the network list did not display my SSID. Also wlan0 mode is still DORMANT.

3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN mode DORMANT group default qlen 1000
    link/ether e4:d5:3d:f3:e7:83 brd ff:ff:ff:ff:ff:ff

Thanks.

Re: [Solved] My SSID is Not Displayed

Since you didn't post any input/output from your attempt to use iwd to scan I will just note that you have to start the iwd service before you can use iwctl.

Edit: this is from my machine...

5: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000
    link/ether 24:77:03:4f:ff:64 brd ff:ff:ff:ff:ff:ff

What matters is what is between the  < and the >

Do you need the SSID list? My SSID is 

nmcli connection show

NAME                   UUID                                  TYPE      DEVICE  
Wired connection 1     7f5ecd61-5e13-362f-bdbe-2d08ecba445f  ethernet  enp19s0 
Jaydip 2.4GHz          0d1dc687-c375-4c6b-a2c8-00987cad8764  wifi      --

Do you think the spaces between the words matter?

Also I restarted the iwd service before iwctl. The difference I noticed, as you mentioned,

3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether e4:d5:3d:f3:e7:83 brd ff:ff:ff:ff:ff:ff

Re: [Solved] My SSID is Not Displayed

What can be found might reveal a limiting pattern.

My SSID is

???
Is this from a different system, then?

nmcli connection show … I restarted the iwd service

nmcli talks to network manager, iwd should not be running when nmcli works (because that means NM runs as well)

Do you think the spaces between the words matter?

At best for specific display tools. Obviously not for nmcli.

Re: [Solved] My SSID is Not Displayed

So how was the "nmcli connection show" output in #6 generated?

Also

It displays other's SSID's from nearer locaions.

What if you move the notebook closer to the AP?

Finally

grep -i SSID

The SSID strings are less interesting for any kind of pattern than eg. the frequencies (eg. whether you only find 5GHz APs)

Re: [Solved] My SSID is Not Displayed

So how was the "nmcli connection show" output in #6 generated?

That was to get my SSID name. It displays all my old connections. Also I have an USB wifi adapter for my desktop computer. I used that here in this laptop. That worked well. But as soon as I removed the USB, wifi stopped working.

What if you move the notebook closer to the AP?

The laptop is next to the router. I am using internet through cable connected directly to the router.

Re: [Solved] My SSID is Not Displayed

The UUID is a networkmanager thing.

Also I have an USB wifi adapter for my desktop computer. I used that here in this laptop. That worked well. But as soon as I removed the USB, wifi stopped working.

Please provide a scan w/ that dongle as well (showing your AP) and also a complete system journal.
Could be a regdomain thing w/ your AP using a channel outside the universally permitted frequencies hmm

Logged into DLink router website. Changed the channel from "Auto" to 1. Immediately, got connected to SSID.

Thanks.
