I'm using Ubuntu gnome 14.04.3. Today all of a sudden I cannot connect to my MTS Broadband network. it is displayed in the nm applet but when I click on it says connecting and the it says 'off'. I tried several times. I unplugged and then again plugged the modem in my computer but with no result. I restated my computer several times. no result. I even deleted the files in
Then again created new connection but no result. I only remember adding these lines:
IPv6 net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1
After watching this video
(the first line I actually typed '#' without the coutes. I cannot write it w/o the quotes here)
How can I connect to the network using GUI?
