Hi, 
My name is LeoI bough a Reliance netconnect a few months ago. The card I use is ZTE. 
I use this along with an IBM R52 laptop. 
Once I connect to R connect, I notice that my laptop get hung sometimes or my machines starts to respond very slowly, application start to open slower. 
I would like to know where could the problem lie, in the card, some software problem or some setting problem.
