WIFI Problems on Pi 3 B, Fresh Raspbian Install (5-27-16)

Fri Sep 09, 2016 10:01 pm

Using NOOBS v1.9 Built Mar 18 2016
On OS install screen, I select networks and can see all my local networks.
I close out of the networks screen and select the recommended Raspbian (5-27-16) install.
During install, I select English (US)
Wait a while for install to finish
Install Successful
Reboot occurs
Desktop loads

I hover my mouse over the computer icon in the top right of the screen next to the bluetooth icon and see: eth0: link is down, wlan0: not associated

I do not have an ethernet cord connected, so eth0: link is down is expected.

I click on the computer icon and can see my wireless networks in the local area.

Here's where my true noob power will reveal itself in spectacular fashion...

If I create a new user in the sudo group and delete the default pi user then when I reboot and log into the new user and try to click on the computer icon it stops working. If i right click on it and try to open network preferences it says it does not have permission.

How can I make a new user account and delete the default account (for security) without my world going to shit and everything breaking?

Thank you for any information.

Have a look at /etc/sudoers.

You will see that the sudo group has permission to run all commands, but the pi user has permissions to run all commands without having to enter a password.

Yea there is a problem with wi-fi in that build but i have built newer versions of Raspbian and they do fix it. Now since you are saying you are a noob for this, Then you can go to https://sourceforge.net/projects/raspbi ... p/download and it will download a more recent build of raspbian (09/05/2016 US, 05/09/2016 everyone else) so if you want to try that you can, ive tested it with my RPI3 and it works for me.

Raspbian Jessie had a bunch of Wifi related updates a couple of months after release. I had problems with some Wifi adapters. Some of those problems disappeared over the first few months of Raspbian updates.

Documentation for drivers is often better in Ubuntu or Debian. Raspbian Jessie is the same as Debian Jessie and Ubuntu 16.

One confusing thing in the documentation and comments is the difference between a driver and the package containing the driver. A package may contain several related drivers and a driver may handle more than one chipset. The following package named firmware-realtek contains drivers for many chipsets. I did not find these pages until I expanded the search from Raspbian to include debian and Ubuntu.

There is an index at https://wiki.debian.org/WiFi.

If you want a fix with that one, https://learn.adafruit.com/adafruits-ra ... cidentalis works just fine as its exactly geared for PI 3
