New R Pi install failed to connect msg when selecting network

nickijerry · 02-24-2021, 11:54 AM

Brand New NOOBS install for R Pi Model B 16Gb SD card. The Startup screen for selecting Wi-Fi network found my local wireless network. Got a failed to connect message after inputting my pass phrase, so I had to skip. Everything else seems to be fine. without the internet connection, I cannot check for updates or access any help files. Spent lots of time in RPi for Dummies and Linux for dummies. So far unable to get the system to present the 'Select Network' screen again so I can double check my wifi PW. In my previous install on this Pi has working fine connecting to the wireless network......... Jerry

Hey nickijerry,

Maybe an obvious thing that you have already tried, but I've had similar issues when the SSID is hidden on first connection (it's OK having it hidden after first connection ...) ... From your description, it sounds like yours is NOT hidden, but just in case ...

Other things to look at : check the encryption type compatibility (ex. AES, TKIP, etc. ...) .. Make sure the wpa_supplicant is part of the base install of your OS ...

Cheers !

Try running : sudo raspi-config

It took a couple of tries for mine to connect, but it will.

BTW Raspberry has it's own forums.

Hidden SSID? Some myths just won't die. The truth is if a bad guy is scanning neighborhood he may even not notice your SSID is hidden until later when he has closer look at discovered networks. Hiding SSID certainly creates problems for legit clients, in particular if more than one access point is used, but never for hackers. MAC filtering as a security measure is another myth.

What security does your WiFi use, WPA2?

Hey Emerson,

No argument with you concerning the issue of how useful hiding the SSID is or not (or MAC filtering), but that would be a completely different discussion

Just bringing it up to the OP in case his AP is configured as such.

Cheers.

changing the default port.... so common, the security through obscurity, it never works, only real security does it.

Edit: To the OP I see no mention of the wpa_supplicant.conf file placed in the / of the install to have it do the automatic connecting, also putting a blank ssh file there will give you that enabled by default too..
