Wifi Address Name Keeps Changing

Hello, about 2 days ago I could not get online with a computer in my bedroom right next to my router. I had just been downstairs on another computer and everything was fine. I checked my router and all of the lights were on indicating it was on line. I checked my other computer and it was fine. I thought maybe airplane mode was on but it was not. I then restarted and it was fine....for a few minutes. I then deleted the address and reentered it. It seemed to be working.

Today after work I got online and all was good then I noticed I was not connected. I checked my wifi to see connections available and my address was there except there was a number 2 after my address. I deleted it and entered the password and all good for about 2 min. I repeated the same thing and it kept happening.

Has anyone here ever encountered something like this? Have I got a virus?
