I had a previous post of similar topic in this blog but that one deals with the Samsung Galaxy Tab. Since the naming of the feature in the menu is vastly different from that of Samsung Galaxy Tab, I took the liberty to post this one specifically for the Samsung Galaxy Y.
Having a personal Wi-Fi hotspot in your possession wherever you go offers lots of convenience to people who prefer using their laptop in browsing the internet and reading and sending email, in the absence of Wi-Fi access points in their location or even at home without regular internet connection.
Once you activate the feature, other people can connect to your Samsung Galaxy Y and use its 3G internet connection to browse the Internet. The only downside of this feature is the maximum number of concurrent users which is set to 5 only.
To make sure that only people whom you authorize to connect will be able to use the service, you have the option to set WPA-PSK security in your device. meaning, you can set a passphrase or password which you can share with your users prior to connection just like in a dedicated Wi-Fi router/access point.
The procedure is very simple and outlined below:
1. Go to "Settings" and tap on "Wireless and Networks",
2. Tap on "Tethering and portable hotspot",
3. Tap to check the "Portable Wi-Fi Hostspot",
By the way, before you do the above-mentioned things, make sure that your phone has enough load credits if you are on prepaid cellular service and that your network's APN is properly configured to browse over 3G. If you can browse the internet on your Galaxy Y prior to setting up the Access Point, then you will have no problem. If you cannot access the internet, check on your 'Mobile Networks Settings" and see if the "Use Packet Data" is checked or activated. This setting determines your phones capability to access the internet given enough load credits and proper APN configuration.
In my case, prior to doing these things, I subscribe first to a day's unlimited internet with my Mobile Network or cellular provider to enjoy unhampered browsing with my pals and family members.
