Question about my router or WIFI

I HAVE AD SERVICE FOR ABOUT 1 YEAR NOW AND I HAVE NOT HAD ANY ISSUES .  I WORK AS A RESEARCHER CREATING SUCH THINGS AS SURVEYS, ETC. WHEN I'M USING MY WIFI AT HOME ON A SAFE SITE MY WIFI DOESNT ALLOW ME TO VIEW ALL OF THE SURVEYS ON A SITE.  MY MOM LIVES NEXT DOOR AND ALSO HAS COX WIFI. WHN I USE HER WIFI WHICH IS NEXT DOOR, FROM MY HOUSE I HAVE MORE ACCESS ON THE SAME SITE AS FAR AS VIEWING THE SURVEYS. WHY DOES THE SITE ALLOW ME TO SEE MORE DIFFERENT SURVEYS THAN WHEN IM USING MY WIFI FROM HOME WHICH ONLY ALLOWS ME TO VIEW ABOUT HALF OF THE SURVEYS?  IS THERE A SETTING I SHOULD BE USING ON MY PANORAMIC WIFI ROUTER? IS ODD THAT HER WIFI OR INTERNET ACCESS ALLOWS ME TO DO MORE.  I HOPE I EXPLAINED MYSELF SO THAT SOMEONE CAN UNDERSTAND WHAT IM SAYING!! LOL
