I have a Dell All in One computer and I bought it new 10 months ago. I have had no prior issues with internet connection until recently and I am using wireless internet, not wired. The internet bars will go from 4 (full) to 1, then after a few seconds to a minute it will go back up to 4, multiple times a day, sometimes as frequently as every few minutes. I have not had any issues with my other desk top or the laptop or any of the smart phones. I have unplugged everything around the computer that could interfere with the wireless signal, I have updated all the drives, removed my AdBlocker program and restarted the computer numerous times. It is really hard to get anything done on it because it is so frustrating, please help!
