I read " Share 3G/4G Mobile Connections
This portable router not just lets you connect to regular internet connections but also lets you share your 3G or 4G connections."
So while this does not answer your first question, why are you unsure about the second question?
Also, why not try Virtual Router first? Link follows.
I use a USB 3G modem (Huawei EC156)to connect to the internet. I want to share that connection across these 3 devices.
a) My Desktop (via LAN)
b) My Android Phone
c) My Laptop.
I will have no problem configuring b) and c). The issue will arise when I will try to connect my PC to the internet via a standard LAN cable. I am not sure whether that router supports sharing via LAN. (i.e I know the LAN port can be used as an input - but I am not sure whether it can be used as an output as well)
Flipkart Link to the modem in question - I have not bought it yet.
So, should I buy it? Will I be able to share my internet across these devices?
