Safari - CANNOT OPEN PAGE

hey guys, yesterday, i started noticing my internet was acting up, and at some instances, it was SUPER SLOW...what would be the cause of this? is it something on my end? or sumthing on ATT's end? heres a SS of the speed test i did yesterday..at 1 time it clocked at .51 mps which i EXTREMELY slow



i went to setting and reset network settings thinking that was it, but still...i got no internet, safari, would have a pop up saying CANNOT OPEN PAGE?

any1 know what the deal is?

its just acting up...sometimes it works, sumtimes VERY SLOW......any opinions are welcomed!

THANKS IN ADVANCED!!!

 

Ok i was messing around with it n found out that my 3g isnt working, that pop up comes out "Cannot Open Page", i turned off 3g n safari worked...its on E...wtf is up with that??? Is it my phone or att?
