I installed vividwireless 4G network broadband connection some 10 days ago. The network comes and go. It is not stable. The speed also fluctuates. And sometimes it is good for laptop but not on mobile phone. I need to reset it and then it works fine on all device. Also I purchased it from optus and they had advertisements of 12 mbps download speed. But when I installed at my house, I only got 4.3. Upon calling vividwireless, they told me my plan is restricted to 5 mbps. WTH??

Guys, please be aware of these hidden conditions!
