Raspberry Pi does not see my wifi network

iba

Hi,

Just got a Raspberry Pi 3 and it does not see my wifi network.

Im using a Virgin Media 3 Router using IPV4.

I have connected the Pi online using a hotspot on my phone which suggests to me there is an issue with the router.

Would be grateful for advice on how to get my Pi to see my Wifi please?

Thanks

What do you have running on the Pi (Raspbian / Retropie).

Can you access a terminal and do the following to see if it helps?

Hi,

Thanks for your quick reply.

I ran: sudo iwlist wlan0 scan

and it listed six cells but not the one that I want to connect to.

What should I do next please - I'm a total noob at this.

Thanks

You might be better off writing it to the config file manually (from the link above).

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

in a terminal.

Scrolling to the bottom of that file and entering:

network={
    ssid="testing"
    psk="testingPassword"
}

Where the ssid is the name of your wifi
and the psk is the password.

Then save the file / restart the Pi just to be sure.

EDIT: Hope this video helps!

Is your router broadcasting the ssid or is it hidden?

Me irl and Kenmc,

Thanks for your help guys. I guess the whole thing was me being stupid.

I was looking for my home wifi name but that was not showing in the top right hand corner.

But I checked for my SSID and that was showing and I was able to connect to that.

I did not realise that that is what I should have been looking for - I've never connected anything to an SSID before.

Thanks for your help.

Cheers

Is your network 5ghz or 2.4?

The Pi can't connect to 5Ghz networks.

Hi,
Network is broadcasting both 2.4 and 5.

If it's the usual Virgin Media router then broadcasting both channels with the same SSID can confuse a lot of devices.

Try ammending the 5Ghz network with "5Ghz" at the end... the Pi should then be able to see your 2.4 network.

Yes, it's the usual virgin router.

Not to sure exactly what you mean. Do you mean go into the router and put quote marks around 5Ghz?

When you're in the router wireless settings you can add "_5G" (without quotes) to that network to differentiate between both.

It's a great idea, and I'm going to do the same!

Can you tell me where to navigate to exactly please - I can't see where I can insert the underscore.

Took me a while to find it again!

If you're in the router settings, it's under Advanced Settings - Wireless - Security.

I'm on the white Hub so not sure if it's different for the Horizon box.

Ive the white hub too - I think its called Media Hub 3.

I went to Advanced Settings/Wireless/Security and see

5 GHz WiFi configuration

but I dont see how I can insert the underscore

Ah, that's grand I'm on the same box.

You should be able to click the cursor and type in to the "WiFi Network Name (SSID)" box for both the 2.4GHz and the 5GHz. You can also change the passwords there. And if you scroll down you should see your connected devices too.

sorry about this.

Yes I see both the WiFi Network Name (SSID) boxes. And I have them both called 'Discworld'.

So are you saying that I should put an underscore before 'discworld' in the 5GHZ box?


'5 GHz WiFi configuration

WiFi Network Name (SSID) Discworld

WiFi Network Name (SSID) broadcast Yes No (The yes option is ticked)

Security WPA-PSK/WPA2-PSK

WiFi password (security key) xxxxxxxxxx'

If you wanted to, yeah!

So the 5GHz one will be called Discworld5GHz (or Discworld_5GHz).

Hi,

By changing the names of the 2.4 and 5.0 broadcasts my Pi was able to see the 2.4 and I was able to connect.

Thanks to you and all that helped.

Appreciated.

Now to get Domoticz working.

Glad you got it sorted.

Never heard of Domoticz before!

...and now I'm shopping for smart bulbs and thermostats... :pac:

I use Xiaomi/Mijia thermostats. Get them on AliExpress or gearbest or geek buying

I use Mi Light bulbs. Again from the same places as above
