Hello I have a question, as I am not very familiar with computers. I bought this router and have a SIM card from Salt in it. However, the internet seems to be enormously slow, although I have full 4G reception in the urban area. Download at about 10Mbit/s, upload mostly higher. So nothing with 300Mbit/s. What is the reason for this? I would like to add a TV, but that won't work either? Thanks for your help!
