Currently in Brazil, and my original MIFI router is a 5 year old Huawei E5573Cs that I bought in the UK. It has always worked great, however I was curious if I could get better speeds so while I was in the UK recently I bought a tp-link M7650. Worked very well in the UK however when I come to Brazil it was spotty while driving though fine once stationary

Issue 2: I can connect to it with my iPhone, but my Google Phone says it has no internet. I tested the network by also connecting to my laptop and no issue there either.

Issue 3: I am unable to make or recieve calls over wifi if connected to the tp-link, however no issue using the Huawei.

I did verify the tp-link has the correct band coverages in country, and I have been tryign to troublehsoot this for the better of 4 hours and I am absolutley stuck.

Any ideas?
