YOTA my new toy

I had broadband cable internet connection. But the provider stopped there business to our university. We have another provider only for our university students, but their internet is limited for each month. It's not comfortable to download desired material for study and others. Recently I have bought 4G USB wireless modem YOTA. Inside my room I get fair signal. But after using a CD at the back side of my modem, I get good (sometimes excellent) signal. The CD works as a reflector like dish antenna. Now my internet problem has solved. Thank you YOTA.
