Computer Hope

My pc was hacked last month ,on my router i accidentally left my wireless on 2g and 5 g by accident. (I use an ethernet cord on my pc) so I did a fresh install of my os, and i downloaded and ran a program called netwatch and it shows two 'routers' on my network, one said cable box arris router the other says arris router, when i go to the connected devices on my router page it just shows my pc as being connected, and my voip vonage box,. I have my wireless 2g and 5 g disabled and i also got a new router

If you did a fresh install and purchased a new router you should be good to go. Just make sure you have strong passwords.
