A client has their showroom located in a place where no provider is able to provide broadband connectivity. The client is unwilling to spend on a leased line as their needs are modest.
We tried a solution where we plugged in a USB 3G data card to a D-link router, connected the router to the wired LAN and had people share the data card's internet connection. We tested this and it works fine.
But, the problem is that the client has around 12 systems and the connection becomes slow, even at 3G speeds (well, actually, around 2 Mbps of real life speed).
The easiest option would be to purchase another USB 3G data card, plug into another D-Link router and connect this second router also to the wired LAN. But, things get hazy for me at this point as I am not a networking person. Is it possible to connect two such routers to the same LAN in this manner?
The idea is to get enough speed to cater to the connectivity needs of 12 systems. Any help would be greatly appreciated.
