[FIXED] Cannot see my WiFi network

[juniwalk]

Hello,
I have bough Raspberry Pi 2 with the official WiFi dongle. When I run this command:

Code: Select all

# iwlist wlan0 scan

I don't see my wifi listed.

Has anyone had such a problem?

Here is some information:

• WiFi is WPA2 Personal with AES encryption
• OS is latest Raspbian Lite
• I have added debian/sid repository and run dist-upgrade
• RPI is right next to the router (in wifi range)
• Interface wlan0 seems to work as it does pickup WPA1 with TKIP networks around

Should run out of the box, its a well supported device.

This is a bit unusual to do, Raspbian is not debian, but a debian derived distro.

* I have added debian/sid repository and run dist-upgrade

No idea what you have done to Raspbian with this.

When you have the latest Jessie Lite only apt-get update/upgrade is advisable.

Better start over and skip this?

WiFi did not work with clean Raspbian Lite either so I think (hope) this is not the problem.

The usual problems can be the reason, like power problems. What is your power supply?
Hidden SSID? Other devices can access Wifi at the same location as the Pi is?

Try with full Jessie and the desktop utility to configure, just to be sure it is Jessie Lite and not hardware/your wifi network (you are running Raspbian Jessie Lite, the latest for raspberrypi.org I assume?)

About the debian SID repository, you are aware that this is even more unstable as Jessie for some seems to be
I would not touch this unless I was a experienced alpha tester and know how to do Raspberry Pi changes also and living dangerously. Not a good idea with also a new hardware platform in my opinion..

From the Debian site:

The unstable distribution (sid)

The code name for Debian's development distribution is sid, aliased to unstable. Most of the development work that is done in Debian, is uploaded to this distribution. This distribution will never get released; instead, packages from it will propagate into testing and then into a real release.

Please note that security updates for unstable distribution are not managed by the security team. Hence, unstable does not get security updates in a timely manner. For more information please see the Security Team's FAQ.

sid is subject to massive changes and in-place library updates. This can result in a very unstable system which contains packages that cannot be installed due to missing libraries, dependencies that cannot be fulfilled etc. Use it at your own risk!

SSID is "JuniWalk-WiFi", not hidden, accessible by notebook and phone without issues.

This is what I have bought:

• Raspberry Pi Universal Power Supply
• NOOBS 8GB SD Card
• Official Raspberry Pi WiFi dongle
• Raspberry Pi 2 Model B
• Official Raspberry Pi Case

I know that SID is unstable I had no problems so far, anyway I am learning with Pi and linux so stability is not what I seek right now

So the problem was a setting of the wifi channel, wifi works now.
