I recently bought a Lenovo Y50-70 laptop, and while Ubuntu has mostly been running well I've had issues with the wireless.
Wifi will connect perfectly fine, and it will usually be able to load webpages for about 30 seconds after boot, but then it becomes completely unable to receive anything at all. Occaisionally it will regain the connection for a few seconds, but this happens rarely and for only a few seconds.
Wireless card is Intel 3160 Wireless, and works perfectly fine on Windows (Windows 8.1).
- rfkill – nothing blocked
- lshw -c network – product: Wireless 3160, firmware=25.17.12.0
- kernel version 4.0.3
I should note that I've already tried the solutions presented in the following posts, but none of them have worked so far:
Cannot Connect To WiFi – Intel Corporation Wireless 3160
Ubuntu Intel wireless 3160 AC not working/slow/disconnecting/unstable
Wifi stopped working after update to 15.04

So far, downloading a newer kernel, downloading a newer firmware, disabling bluetooth, renaming firmware, setting options as described here haven't worked.
Any help would be much appreciated.

The command in the post you linked is:
It will over-write the existing text in the file /etc/modprobe.d/iwlwifi.conf. It should have read:
The '-a' modifier appends the new text to the end of the existing file.
In Ubuntu 15.04, the default file reads:
That text is necessary to properly unload and reload the module
iwlwifi
if necessary. I suggest you do:Use nano or kate or leafpad if you don't have the text editor gedit. Copy and paste the text I included above the line you added. When you are done, it should read like this:
Proofread carefully, save and close the text editor. You should be all set.
