WIFI is not getting connected although there is no issue with Network

Generally peoples getting issue with wifi many times due to different different reasons among them one is Antenna issue.

If you are a person who has the Hardware knowledge then you will know there is two or three wires connected to WIFI card which is inside of laptop or latest slim panel desktop.laterally we will get two cables connected to WIFI card one is white and another one is black colored cable.
The white one is the main Antenna and black cable consists for auxiliary antenna.if these two cables are not connected properly then we will not get wifi also.so we have to trouble shoot some basic things first like

1.On and off network.
2.Disconnect and reconnect the network.
3.Disable and enable network adapter.
4.Try to connect another network.
5.Restart system.
6.Updating drivers.
7.Update Bios version.
Then after if you are not able to connect the wifi then remove the back  panel of laptop where having the wifi card and try to clean once the card with the help of eraser and unplug the antenna connector  if it is removed previously then connect it properly then try to connect wifi i think your problem is resolved.if not please write your comment i gill get back to you soon with solution ...........................
