Sharing the connection at home
Step 2 above walks you through how to set up a 3G or 4G modem for a single laptop, but what if you also want to use the mobile internet connection when you get home, sharing it with multiple computers or using it as a backup to a fixed internet service like ADSL?
The wireless modem option outlined in Step 2 is one solution. The modem creates a wireless network that multiple PCs can see and connect to. Any PC connected to it can access the internet.
A more robust alternative is a home router that supports 3G. Some broadband (including ADSL and cable) modem routers have USB ports into which you can plug a USB 3G modem.
Mobile broadband is really flexible – you can use it on the road and, with a 3G capable router and USB modem (pictured), at home as well.
If you have a USB modem for 3G, you can unplug it from your PC and plug it into a router when you get home. That shares the connection with everybody on your home network, wireless and wired. It can also be configured in the router as a backup – if the main home broadband connection (for example, ADSL) goes down, then the 3G connection automatically takes over.
If you want to do this, though, you need to look for a router that specifically supports 3G. Just because a router has USB ports doesn’t necessarily mean it supports 3G modems!
