Hello all, I'm Lee -'intermediate-Linux-user' with a problem.
Bought a new HP Probook 455 G2 with "OEM Ubuntu 14.04 LTS" -arrived with 12.04 LTS. Little embarrassing for eBuyer, but not a problem for me as I was going wipe and clean install -I like my partitions just so....
/Boot > 200MB > Ext2 > Primary
/ > 10GB > Ext4 > Primary
/usr > 40GB > Ext4 > Primary
Swap > 2GB > Linux-Swap > Logical
/home> to 1TB end > Ext 4 > Logical
On clean install of 14.04 LTS I had ethernet plugged in for updates etc during install which worked fine. On reboot I removed the ethernet and found that the wireless 'worked' (i.e. the card was detected fine), but no networks were found; my phone and desktop are fine with the wireless network so it's an idiosyncrasy of the laptop....
Some useful information, I've tried to be thorough as for as my knowledge goes:

lee@xxxxxxx:~$ sudo iwlist wlan0 scan

Any ideas why I have a device that's correctly installed, but won't scan for or find networks?
Cheers!

I've just found the Wireless Troubleshooting page with the diagnostic code, output follows:

**UPDATE #2**
Further news... I ran the following commands and I can now SEE the wireless networks available to me:
lee@xxxxxxx:~$ sudo modprobe rtl8723be msi=0
[sudo] password for lee:
lee@xxxxxxx:~$ more /sys/module/rtl8723be/parameters/msi
N
lee@xxxxxxx:~$ sudo modprobe -r rtl8723be
lee@xxxxxxx:~$ sudo modprobe rtl8723be msi=1
lee@xxxxxxx:~$ more /sys/module/rtl8723be/parameters/msi
Y
However: still doesn't connect to the selected network. It makes out like it's trying to and then tells me it's disconnected from the network...
...and so it continues.
**UPDATE #3**
Update #2 is persistent on log-out/log-in, but not on reboot. Oh well....next!
Bought a new HP Probook 455 G2 with "OEM Ubuntu 14.04 LTS" -arrived with 12.04 LTS. Little embarrassing for eBuyer, but not a problem for me as I was going wipe and clean install -I like my partitions just so....
/Boot > 200MB > Ext2 > Primary
/ > 10GB > Ext4 > Primary
/usr > 40GB > Ext4 > Primary
Swap > 2GB > Linux-Swap > Logical
/home> to 1TB end > Ext 4 > Logical
On clean install of 14.04 LTS I had ethernet plugged in for updates etc during install which worked fine. On reboot I removed the ethernet and found that the wireless 'worked' (i.e. the card was detected fine), but no networks were found; my phone and desktop are fine with the wireless network so it's an idiosyncrasy of the laptop....
Some useful information, I've tried to be thorough as for as my knowledge goes:

Any ideas why I have a device that's correctly installed, but won't scan for or find networks?
Cheers!

Hopefully this is better info!
**UPDATE #2**
Further news... I ran the following commands and I can now SEE the wireless networks available to me:
lee@xxxxxxx:~$ sudo modprobe rtl8723be msi=0
[sudo] password for lee:
lee@xxxxxxx:~$ more /sys/module/rtl8723be/parameters/msi
N
lee@xxxxxxx:~$ sudo modprobe -r rtl8723be
lee@xxxxxxx:~$ sudo modprobe rtl8723be msi=1
lee@xxxxxxx:~$ more /sys/module/rtl8723be/parameters/msi
Y
However: still doesn't connect to the selected network. It makes out like it's trying to and then tells me it's disconnected from the network...
...and so it continues.
**UPDATE #3**
Update #2 is persistent on log-out/log-in, but not on reboot. Oh well....next!
