So, In my area we have upgraded to the most mbps we can get, which is low.. The highest Mbps we can get is 6 Mbp/s. We upgraded our internet yesterday from 3 Mbp/s to 6 Mbp/s. and the AT&T person said to unplug the modem and plug it back in tomorrow (which is that following day). Now today, I went to go check the download/upload speed using Ookla and Testmy.net. They both say I'm still running on 3 Mbp/s.. and we paid for 6 Mbp/s and we also unplugged a replugged the modem like 5 times.. Still, we are getting 3 Mbp/s. Any reason??
