Sorry I can’t as I am always have to be online for office work on laptop as well. Any other way?
Well, yes. A hardware firewall is always safer than any software solution. But your FW blocked this thing, didn’t it?
fine tune your software firewall and pray god that it works 
Of course you can get a router. Your modem will connect into the router then your laptop will connect to the router. If you rely on only a software firewall for inbound and outbound protection then you are asking for trouble. Most modern day modems have a hardware firewall. My 2Wire Gateway has a hardware firewall.
he’s on 3G :
Don’t tell him what he can and can’t. He’s using his laptop and I suppose he is travelling with it a lot, doing business.
Its advice. Gezz…If he is traveling a lot then he can use HotSpot Shield.
Logos, I always have and always will love you… ;D
What is Hot Spot Shield?
A portable hardware firewall?
Sorry again but As I said I don’t have much knowledge in networking…
Plz tell how can I connect my USB modem to router ???
Well for Outpost I have everything at maximum and its working fine for me
Dont ask…Google it. :
no , seems to be a VPN to secure hotspot wifi connections
Now I realize how important this networking is. I never had my interest in this field, I only wanted to be a good programmer…
And thanks alot all of you. You people are so knowledgeable … 
anyway the guy’s on 3G mostly, and securing wifi hotspot connections is nice… when he’s not on 3G anymore ;D >>>> and hotspots are available
I have a house outside the city I am going to retire to, so I use a Verizon USB 760 3G modem. I have a Cradlepoint router MBR900 that is made to use the USB760 modem. Of course the router has a firewall. The router also has the ability to use imput from your cable system and also allows you to connect to your computer wireless or wired. It has worked great for me. They also make a portable unit. I bought mine at Best Buy but they do not carry all models. Check their website for more models. I am not trying to push a prduct but it sounds like to me that you may not know that something like this is available. I did not know they make routers that would take USB modems. Be careful you have to check the model you are buying to see if it works with the modem model you are using. They have a list for each router what modems it will work with. Hope this helps.
that stingray thing only supports RJ45 ethernet cables, you can’t plugin a 3G key in it : … anyway such solutions need to be constantly powered from an external power source I suppose, so they’re useless when you’re on the move.
edit: confirmed The power adapter plugs in right in between the PC and Modem cables, so you will need power nearby your Stingray Firewall unit.
“Stingray is very portable, and if you have a universal poweradaptor it can be used while travelling abroad.”
Now all we need is a portable power-outlet socket.
I forgot to say the Cradlepoint will also can use the Verizon Hotspot and has a RJ45 and usb port.
