Internet Connection Sharing via Wifi

Having two or more personal laptop or PC on home nowadays is not an extraordinary thing. Especially for those who play in rough with IT sector or gadget freakier, I called it “a-must have”. Survey research result found on internet clarify that 91 percent of those who have a netbook also own a laptop and 87 percent own a desktop. Some husband also equip their house with two laptop for their wife, so that there’s no more problem for both of them to kill their each pleasure time – husband working on his spread sheet business and wife sharing minds with her facebook page. But, how about if husband need to send email his work immediately while his wife still browsing for her lingerie on the internet? No problem at all if they have both modem, but troubling wife for her modem might become a big problem. This article will assist you how to setting up internet connection over wireless signal built-in on common laptop or PC, it’s a cheap trick than buying a new modem and more practice than using a cross cable.

First of all, make sure that both wifi on each PC or laptop is currently exist and active. Set wifi IP address on host machine where the modem plugged in (I used my 12” Travelmate 6291 for this) with and subnet mask with just like picture below:

From Wireless Network tab on the same Wireless Network Properties window, click Add button to add wifi network identification name. From example, I named it with “TravelMate” and configured it with Open Network Authentication. Don’t forget to check “This is a computer to computer (ad hoc) network“ on bottom of the window.

To test whether it succeeded or not, let the machine search for current wifi signal. It will found at least with your existing network name you made already. On example, it will display “TravelMate” wifi connection.

Next, plugged in the modem and activate the internet connection link. Mine was particularly Huawei E160 dongle USB modem with Unlimited IM2 Broom ISP SIM card. After the link is up, click on Advanced tab from properties window, check for Internet Connection Sharing and make sure to share it over wireless network connection.

Done for the host connection, now get ready to switch to guest device. Set wifi IP address from guest device to with same subnet mask but point to host IP address as both gateway and DNS address (

Now, let the guest search for existing signal. It will found host wifi network signal (example: “TravelMate”) and make it try to connect to host.

After it succeeded “paired”, try to pinging an internet host from command prompt or you can open a page from browser directly. That’s all, if there’s nothing left, both device will have internet connection from single modem plugged in on one of the computer.

PS: I dedicated this article to my buddy and blessed for his brand new 10” Lenovo Ideapad S10 with Veriface Recognition software that I finally cracked and working on my Aspire One.

    I've done it before, but with bluetooth & never with wifi dongle since I didn't have it.

    Anyway, - for your first answer - did you have tried steps above I mentioned? I though that it has the same concept & I believe that it'll works.

    But somehow, your LAN (or it still our?) is kinda complicated (I mean both with the hardware & "brainware" ;-). Consult please with the network administrator & you will get your second answer. I'm backing up with the third answer, since I'm not ... really "there".

    PS: I bet you never get the third answer. Am I correct?
