“My LT400 V2 router has suddenly stopped working without being bumped or turned off. Diagnosis returns me “4G has obtained the IP address but cannot access the Internet” and “DNS is abnormal”. I have tried resetting it, firmware upgrade and contacting you via email but no results. It never gave me any problems before but now it is unusable.”

“This router leaves a lot to be desired in terms of initial set up, I have set up many routers , I have to say this one is the worst. All SIMs tested were good, good signal etc. Still a pig to set up and get connected. The mesh function should disable all together, there are no instructions on the external antenna options, and which connector to use etc. The firmware upgrade function can be set to automatic, but if you want to do it manually you have to ask support for it ,, WTF,, I am thinking in returning this unit, no time for this BS, sorry , no mater what I try,, NO FRIGGING CONNECTION ,,,, switching back to TP LINK”
