How to set up Wi-Fi hotspot with a phone running Froyo

When Google released Android 2.2 "Froyo", the upgrade of "Eclair" (Android 2.1) they introduced  the ability to set up a Wi-Fi hotspot. A  Wi-Fi hotspot allows you to use any phone running "Froyo" to act as a wireless modem using the phones data network (mobile internet). This opens up the ability to have the internet wherever you go, so say your on the train and want to browse the internet with your laptop, all you need to do is set up the hotspot and your read to go as long as you can recieve a mobile internet signal.

The first step to setting up the hotspot is opening the settings screen on your phone. To do this press "Menu" on the home screen and then click on "Wireless & networks". Inside this menu you should see an option saying "Portable Wi-Fi hotspot settings". In here set up the name of the hotspot and a password (if you want to have one) and then click on the tick box beside "Portable Wi-Fi Hotspot".


After doing the above you will need to scan for Wi-Fi connections on your laptop
and find the connection that has the name you set up on your phone. As I was using a HTC Wildfire for this example I've set up the connection as "HTC Portable Hotspot" though feel free to call it anything you wish.
If you had a password set up on the connection for security you will then be asked to enter it.

After doing this you "should" be ready to go. For some reason whilst doing this guide I managed to stumble into some form of problem, clicking on "OK" seemed to send Windows into correcting the error. Repeated attempts to replicate the error haven't seen them come up so I'm not too sure what the error ACTUALLY was.

To stop the connection go back into the "Wireless & network" settings and untick "Portable Wi-Fi hotspot".

Whilst it's a useful feature and it is well implemented in phones running Froyo a few issues do need to be pointed out before you start. Firstly using a phone as a Wi-Fi hotspot will drain the phones battery at a quicker rate than usual which can be problematic though maybe a bigger issue is that the phones internet allowance will be eaten into. Unless you are on an unlimited internet deal I'd advise being careful when using a phone as a hotspot as you can run up a bill from the network data.

It's also worth noting some networks have made it difficult to use a phone as a modem, often if you call your network they can help you sort out any issues and barriers they've put in their users way.

How to use your Samsung Galaxy S2 as a portable Wi-Fi Hotspot

The technology of today is simply amazing, I think we'll all agree that what we can do now with phones is amazing and it doesn't seem like we'll be finding a limit on what they will do any time soon. One of the great features of the current Android is their ability to act as a portable Wi-Fi hotspot, something that was completely unimaginable 10 years ago. This guide will walk you through the task of setting up such a connection and also look at some of the issues of doing it.



Firstly you need to open Settings screen (see right) and click on the Wireless and Network option at the very top of the list which will open an options screen like the one to the left. As you can see in the screen shot there is an option for "Tethering and portable hotspot", you need to click on this option at this point to open yet another menu. This will open up a menu with 3 options. "USB Tethering" (only available if you've got your laptop or PC connected to your phone), "Portable Wi-Fi hotspot settings" and "Help". The one you need to click is "Portable Wi-Fi hotspot settings" (see the screen shot to the right as a guide).

After clicking on "Portable Wi-Fi hotspot settings"you'll see a screen like the one on the left called "Introduction to portable Wi-Fi hotspot".This screen will explain the basics of what a Portable Wi-Fi hotspot is though really doesn't act so much as an introduction but more as a chance to go back. If you are still wishing to set up the hotspot click "OK" at this screen.

After clicking OK on the previous screen you will see the screen to the right. Now I would advise, if you live in a city mainly (thankfully I don't) that you click on "Configure portable Wi-Fi hot" and put on some security (using a password with the WPA2 PSK option) though if you don't you'll find it as an open connection. When you've decided on your security you need to tick the check box.

 After ticking the check box neck to "Portable Wi-Fi hotspot" a warning will appear on the screen (see the screen shot to the left). If you click OK you're ready to go and you will notice a new blue icon along the top that sits on the notification bar. In regards to the phone that's everything you need to do before going back to your laptop or computer.

On your laptop/computer you will need to see what Wi-Fi connections are available. If you didn't change the name of the connection it should appear as "AndroidHotspot" then some numbers. If you went into the configuration screen you can re-name them and things to whatever you want such as "Dave's hotspot" or "Jenny's phone".
 On this screen you need to click on the Android connection (or whatever you re-named it to) and connect as you would usually do so. When you first use the
  connection you may come across a screen shot like the one on, quick whichever best applies to you and within seconds you'll be connected and using your phone as a Wi-Fi hotspot.



Now we get to the problems, and there is a fair few of them. Firstly as one screen shot said using a phone as a Wi-Fi hotspot consumes the battery, and quickly (so I'd advise plugging it into an electric socket if you can) and it will swiftly eat into your data allowance. Remember desktop browsers aren't made with 500MB allowances in mind and you can easily go over your limit with out even realising. Also from the browsing point of view your speed is limit to what mobile internet you can get so trying to use a "G" connection for anything other than checking E-mails will be a pain.

Although it's a very handy tool, it's one that you're unlikely to be using outside of emergencies and maybe train rides. Where possible I'd advising using your home internet, public Wi-Fi (Cloud, BT Openzone and similar) or just using your phone (which compresses webpages for mobiles) for anything online.
