I bought a TP link M7350 recently, and someone i know also have the same brand and model. I am having connectivity issues and asked that someone for advices. He told me to select the 5GHz in the wireless band selection however, when i looked for it, 2.4 GHz was the only one available. He showed me another way to look for it in the pocket wifi itself, and my wifi doesnt have the "wireless band" option.
