Non matching ip adresses

Hello Everyone!!

Our wifi was bought out by another company…Kwikom. They recently had my husband change a setting in our router…now Tablo keeps saying Roku and Tablo ip addresses do not match. I have to work really hard to get my tablo connected now…it was hard cable connected…now i have to wifi connect and have my tablo app on my phone and on roku searching at the same time to get it to connect…it takes forever to even pull up recorded movies…hard connect it was not an issue…help please!!

Thank you from an “aggravated” “tech not so smart” Steph
