We just upgraded from the lightning 10 to 25 plan, because we've been getting really slow mbps speeds. It's usually from 300kbps to 5mbps, lucky if we hit 5 though. After upgrading we called tech support and our mbps hit 15-20 for about 10 minutes then back down to 1.2mbps. We have 3 TV boxes, 4 phones a ps4 operating over wifi and usually they are not all in use at the same time. I know that's alot but there's no way we should be getting even less of a 1/4 of this plan. Any help would be appreciated!
