If I buy a USB Wifi router for my BSNL EVDO modem (ZTE AC8700),can anybody please guide me step-by-step to configure it so that I can use it for my laptop as well as my mobile. I can even share the signal with my friends with wifi handsets. There are routers available of brand EK Wireless, Leoxsys etc (I'm attaching pics). There is another option: if USB female to RJ45 male connector can be procured, cheaper wifi routers can also be configured.
Portable USB wifi routers with built-in Li-ion battery are also available which are handy and through which EVDO signal can be accessed on mobile anywhere and on the move also.
Anyways, I need guidance. Please help
