Wifi not detected

I recently installed #! on a Toshiba Sattelite C850-B559 laptop.
Wifi is not detected, only wired connection is available.
This might help:
ifconfig

	Hard blocked: no

same as sudo modprobe rtl8723

sudo modprobe rtl8723
FATAL: Module rtl8723 not found.

Thanks in advance

Re: Wifi not detected

You appear to have an rtl8723ae which should be supported by the firmware-realtek package -- do you have this installed?

If you do, post the output of:

dmesg|egrep 'wl|firmw|dhc'

Re: Wifi not detected

Do you have the firmware-realtek package installed?

apt-cache policy firmware-realtek

Re: Wifi not detected

This is what I get:

apt-cache policy firmware-realtek
firmware-realtek:
  Installed: 0.36+wheezy.1
  Candidate: 0.36+wheezy.1
  Version table:
 *** 0.36+wheezy.1 0
        500 http://http.debian.net/debian/ wheezy/non-free i386 Packages
        100 /var/lib/dpkg/status

is it because mine is i686 and the package installed is i386? I've read that you could install i868 on i386.

No, that's fine, "i386" is the cover-all term for 32-bit systems.

Any blacklists?

grep -R blacklist /etc/modprobe.d

If "rtl8723" doesn't show on that list, all I can think to suggest is to try a newer kernel version from the wheezy-backports repository:

Re: Wifi not detected

First thing I would do: remove tint2

sudo apt-get autoremove --purge tint2

Second thing: ... to stop this:

Err http://packages.crunchbang.org waldorf Release.gpg                                                                                       
  Could not resolve 'packages.crunchbang.org'

... Edit your sources.list and remove the crunchbang repos and change to "wheezy", similar to but not necessarily like this:
EDIT: You have wheezy

## CRUNCHBANG
## Compatible with Debian Wheezy, but use at your own risk.
##deb http://packages.crunchbang.org/waldorf waldorf main
##deb-src http://packages.crunchbang.org/waldorf waldorf main

## DEBIAN
# deb-src http://http.debian.net/debian wheezy main contrib non-free
deb http://ftp.us.debian.org/debian/ wheezy main contrib non-free

## DEBIAN SECURITY
deb http://security.debian.org/ wheezy/updates main
#deb-src http://security.debian.org/ wheezy/updates main

## deb-multimedia
## deb ftp://ftp.deb-multimedia.org wheezy main

Third thing: reinstall a newer tint2

sudo apt-get install --no-install-recommends tint2

Then do the update/upgrade commands

The Crunchbang package repo has been off-line for a while, so you won't be able to fully install #! from scratch anyway.

Do you have a particular reason for wanting to use a distro which is now 3 years out-of-date? BunsenLabs is the community continuation, and is perfectly functional as a CB replacement.
