I was given an old Gateway laptop MA2A MX6121. I have used it before online wireless. The previous owner bought a new one and this one sat on a shelf for months. I got it and cannot figure out how to connect to the internet. I have even plugged it directly in to my router and can't figure it out. I ran a Malwarebyte scan due to a popup I was getting when I turned the computer on and found 16 viruses. The popup is gone now. I'm not sure what info I need to include. Any help would be appreciated! Thanks
