Zte Usb Modem Kinda Malfunctiong...help

[legendary112 0]

Hello guys,I bought a zte tu25 4g broadband modem a few months ago about two actually. like most usb modems it heats up from time to time but i've tried to be cautious and when it heats up, i'd disconnect it for a few minutes. I've only left it connected on the internet to finish some downloads a few nights definitely less than five.however for the past two days, its not been holding connections well. its disconnecting after every few minutes and reconnecting. and when I plug it in for the first time, sometimes its not being recognized instantly. sometimes there's a pop up that comes up saying i should put it in a faster usb port...my head is in a whirl, i don't know what to do...is't faulty now? my isp is upgrading their network, could this be the reason? unfortunately i'm unable to talk to them right now..please someone help!!
