Not Getting Gig speeds On New Service

same issue, same modem. Ubiquiti gateway and infrastructure. called tech support and had me restart the modem and he restarted it like 10 times till speeds got a bit better. but nowhere near what im paying for with gigblast. refused to connect me to level2 tech saying its only for customers that have their equipment. told me to call arris for a firmware update. ive had gig for a year and never got close with the speeds. replaced the 2year old arris 8200 and nighthawk X6 when internet service started dropping off. gave them the benefit of the doubt and i was hard wiring most of the devices in a nework cabinet. and nothing. same drops and same ** speeds. i guess ill call one last time and see what happens. this past year has bees BS after being with them for 20 years. i guess good thing wow moved in this past fall and offer gig internet
