So recently I was having internet issues with my modem, and none of my devices would get over 30Mbps. Well i fixed that and they all get around 90 now. But when i go to do a speed test still on my 6+, it is still only at 30Mbps. I tried so far reseting the network settings, restoring it as a new phone, and doing a hard reset. If any one else would have any ideas that would be great.
