Hi everyone, I have a Presigio Multipad 7 pro (won't be buying this brand again but that's another story). I need to use it in my shop as an internet source. I have a 3G dongle and a TP Link TL-MR3020 mini router. The router works perfectly when connected to my laptop with a cable, but I CANNOT get the tablet to connect. No matter what I do it comes back with "Authentication problem"....aaaaagggghhhhh I have tried going the http;192.168.0.1/ route as instructed but never seem to be able to connect! So I can't "get in" to the router to see what's going on. ANY IDEAS PLEASE?????
