Jasdeep Khalsa, as per http://support.lenovo.com/us/en/products/laptops-
and-netbooks/lenovo-y-series-laptops/y50-70-notebook-lenovo an update to
your computer's buggy and outdated BIOS is available (2.01). If you
update to this following https://help.ubuntu.com/community/BIOSUpdate
does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then
please mark this report Status Confirmed.

Thank you for your understanding.

** Description changed:

- -------------------------
- Summary of my particular setup
- -------------------------
- I am using a Lenovo Y50 Laptop which includes the following network cards/adaptors (which I checked with `sudo lshw -class network`):
+ When I attempt to use wifi it keeps saying its authenticating and then
+ does not connect. I can see all the 2G wifi networks. Network manager
+ will keep trying for up to an hour and then suddenly it will connect
+ like magic! Also, I have installed both WICD Network Manager and
+ Ubuntu's Network Manager on my system, but I am only using Ubuntu's
+ Network Manager.

- 
- 
- I have read reviews that these adapters are not very good - i.e. they
- are a bit old. They also cannot find 5G wifi networks, only 2G ones.
- 
- The laptop came with Windows 8.1 64 but I installed Ubuntu 14.04 64 Bit
- alongside Windows, even though I only boot into my Ubuntu partition now.
- 
- Also, I have installed both WICD Network Manager AND Ubuntu's Network
- Manager on my system, but for the purposes of this bug I am only using
- Ubuntu's Network Manager i.e. I am not opening WICD. I am including this
- information in case even installing WICD may be causing a conflict.
- 
- -------------------------
- The problem
- -------------------------
- At work I use Ethernet, so when I plug the cable in in the morning my computer connects straight away to the internet through Network Manager!
- 
- When I come home, I use wifi and expect it to connect straight away but
- it keeps saying its authenticating and then does not connect. I can see
- all the 2G wifi networks, but network manager just cannot connect to
- them straight away. Network manager will keep trying for up to an hour
- and then suddenly it will connect like magic!
- 
- -------------------------
- What solutions I tried that did not work
- -------------------------
+ I've tried:
  * Using software updater to update my system fully
  * Restarting my laptop
  * Restarting the router
  * Connecting to the wifi with my phone (works fine!) whilst I am struggling to connect with my laptop
  * Disabling network manager and re-enabling it
  * Disabling wifi then re-enabling it
  * Disabling wifi and networking and then re-enabling it
- * In Terminal: `sudo service network-manager restart`
+ * In Terminal: sudo service network-manager restart
  
- -------------------------
- What I am going to try
- -------------------------
- * Move fully to WICD (which I have done in the past!) OR delete WICD totally and only keep network manager
- * Check to see if my particular card has any known issues with Ubuntu and try to solve those
- * I'm open to other suggestions
