How to connect android phones to multiple Wi-Fi hotspots

HOW  TO CONNECT ANDROID PHONES TO      MULTIPLE    Wi-Fi  HOTSPOTS

Using Android, it’s easy to connect to multiple Wi-Fi networks, so you’ll never have to connect to the web when you arrive home as the device is already connected.

With Android, it’s incredibly easy to set up separate home and work Wi-Fi connections, so whenever you walk through the door your Android device will automatically connect without even asking.Explore the Market and you’ll find exciting third-party apps that add even  more functionality to your smartphone. Follow us over the next two pages as we explore the various Wi-Fi options built in to the Android OS, and take a look at some free apps intended to make life even easier.

1 .Turn on Wi-Fi

As you read this there’s a high chance that multiple Wi-Fi connections are

available all around you. To find out if  that’s the case, tap the Menu key on your Android device, choose ‘Settings’ and then ‘Wireless & networks’. If Wi-Fi isn’t already enabled, check the tick icon to begin.

2. Connecting

Tap ‘Wi-Fi settings’ and you’ll see any available connections. Tap on one to

connect. If it’s an open connection then a network signal will automatically begin. Otherwise, enter the password to connect.

3.Automatic connecting

You’re now connected to a Wi-Fi connection. Every time you enter its

radius your device will automatically connect, so you’ll never have to enter

the password again. To disconnect, tap and hold on the connection, and

choose ‘Forget network .

4 Advanced

To rescan for available connections, tap the Menu button and choose

‘Scan’. By tapping ‘Advanced’ you can enable the Wi-Fi connection to

stay permanently connected, never turn off when plugged in, or only turn

off when the screen is turned off .

5.IP settings

You’ll also find various IP settings, including the ability to use a static IP,

enter a new IP address, DNS settings,and Gateway settings. These settings are only recommended for network professionals or people who really  know what they’re doing.

6 .Widgets

You can also connect and disconnect from Wi-Fi connections using the

Power Control widget. To add it to your home screen, press the Menu

key, choose ‘Add’, then ‘Widgets’, then tap on the Power Control widget.

7. WeFi

Within the Android Market you’ll find a number of Wi-Fi apps that make life

easier for connecting to various networks. WeFi is a fantastic app for

connecting to free Wi-Fi connections, the type you’ll find in coffee shops,

other public businesses, or those who enjoy sharing their home connection.

8.Automatic

WeFi automatically connects to the strongest free Wi-Fi hotspot, saving

you having to manually connect. The app references a constantly

updated database of free hotspots to determine which are the best

available connections.

9.Wifi Analyzer

Another great free app is Wifi Analyzer. It shows all available

hotspots on a graph by signal strength and interference. If the graph is

crowded with too many signals then it’s also possible to view the

connections in list form.

10.Settings

Wifi Analyzer is packed with clever touches. Via the Settings menu you

can alter the graph colours, rescan for connections, keep the screen

turned on, automatically connect to networks and also disable the banner

ad at the bottom of the screen, if that bothers you.

FAQ    RELATED   TO   Wi-Fi

Simple Steps to upgrade The SSD of your computer

How to Upgrade The SSD

Time needed: 60 minutes

Difficulty rating: 4/10

A solid-state drive (SSD) is one of the most significant upgrades you can make to any PC. Mechanical storage now acts as a massive  bottleneck to overall performance, and with modern SSDs offering anywhere from five and 50 times the performance of a mechanical disk depending on workload, a drive upgrade can restore snappiness  to even the oldest of systems. Laptops tend to be fussier with SSD brand than their desktop counterparts, so our advice would be to opt for an Intel or Samsung drive where possible. Initially we used a G.Skill SSD for this project, but its power up cycle was too slow forthe laptop’s POST sequence, causing the laptop to fail to boot at least one in three times. For this reason, our upgrade technically consists of  moving from one SSD to another!

You may want to use the drive upgrade as an excuse to reinstall your operating system. If you keep a tidy ship, however, this is probably a waste of time, as you can simply clone your software from one drive to another instead. There are a couple of methods that will facilitate this. The quickest way is to remove the source drive from the laptop and connect it up to a desktop PC. Use software to takea snapshot of this drive and then write the resulting image file to the new SSD. You then just pop the new SSD back into the laptop and it should boot into Windows as if nothing happened, albeit at a vastly improved speed. If your PC has two spare SATA connectors available, you can even connect both old and new drives at the same time and copy the contents from one to the other. If you don’t have a spare desktop PC to hand, then you can connect the new SSD to the computer via a SATA to USB convertor cable. 

These cables can be purchased for less than £10 and will convert your SSD into a temporary external hard disk. You then, once again, use cloning software to copy the data from the original source disk to the new drive instead. As it’s a little more involved, we’ll be using the desktop cloning method for our step-by-step guide. It might seem like more than a faff to take out your drive and plug it into a desktop, but the datamigration should only take 15 or 20 minutes for 100GB of data,compared to potentially several hours over USB. 

If you have a fast gigabit Ethernet network, you could even be extra crafty and image your laptop drive to a network device, meaning you only need connect up the new drive before imaging.

Step 1. Ensure you don’t have too much data!

SSDs might be lightning fast, but they tend to be considerably smaller in capacity compared to mechanical drives unless you spend a lot of money. For this reason, you need to make sure that you don’t have too much data for the migration. First of all, tackle the  usual suspects like music files (particularly iTunes directories),downloaded movies and photos. If you’re still struggling for space, consider uninstalling any games you have on the PC; these are notorious space hogs. If you don’t really know where the bulkof your space is being used, consider downloading the fantasticbut obscurely named WinDirStat, which will break your files and folders down into an easy to visualise diagram, with larger blocksrepresenting a folder taking up a load of space.

Step 2. Remove your existing HDD

Our MSI laptop has a discrete hatch for the storage drive separate from the main guts of the system. This makes it very easy to gain access to the drive. First of all, we remove the two small screwskeeping the hatch closed. Once out, we popped off the plastic cover to reveal the HDD. To remove the existing SSD we used the metal retention frame to very slightly lift the drive up before pulling it away and out of the SATA plug. The drive simply un-slots from this connection. The SATA and SATA power connectors on a laptop 2.5”are the same as those used in desktops.

Step 3. Attach the SSD to the desktop

Hooking up the 2.5” HDD to your desktop is just like installing any other drive, though we wouldn’t recommend you bother mounting it to the case. Just make sure it’s carefully balanced and you can umbilically connect it to the motherboard. Once connected, ensure your boot order on the desktop is still correct or it may attempt to boot from the SSD. All being well, the drive will be detected by Windows on your desktop and appear as a secondary drive.

Step 4. Take an image of the laptop HDD

If you already own useful cloning software like Acronis True Image, you can use this to facilitate the transition. If not, then we recommend you download Macrium Reflect - freeware cloning and imaging software that is ideal for this kind of task. Using Macrium, you simply select the laptop HDD as the source and click ‘Image this disk’. Save the image to your desktop’s storage drive. Once done, shut down the desktop and remove the laptop hardware, this time connecting the SSD.

Step 5. Restore image to new SSD

Windows should detect the SSD once the desktop has started up, but do not be alarmed if it doesn’t appear in Windows Explorer, as it would need partitions to be present in order to be seen by the OS. Fire up Macrium Reflect again and click on the restore tab. Locate the image file you created in step 4 and point the software to the new SSD. Be sure that the sizes of partition are correct and will give you the full space of the drive and, most importantly, that the partition alignment is set to Vista/7/SSD. This can be used to convert a Windows XP based partition to an SSD-friendly partition alignment. While an incorrect partition alignment won’t affect functionality, it will cost you performance and increase wear level on your SSD.

Step 6. Install the SSD back in the laptop

First we needed to transplant the metal retention frame from the old drive to the new one. This was done by replacing two small screws. Secondly, you align the SATA power and data connections carefully before pushing the drive home. It should move in approximately 5mm and the frame will then fit flush once again. Different notebooks employ different kinds of retention frames, so refer to your laptop’s service manual if it isn’t obvious what you need to do. Replace the rear cover and, all being well, your laptop will boot back up quicker than ever before!

How to Replace the Memory of your Laptop : Tech Speakers

1.Replacing the Memory

Time needed: 10 minutes

Difficulty rating: 3/10

Before upgrading the memory, you should refer to the service manual of your laptop to find out where the memory slots are. In larger laptops you’ll normally be fortunate enough to find them under a hatch on the underside of your laptop. On more compact variants, at least one of the memory slots may be hidden under the keyboard,  making it a far more involved task. Removing a laptop’s keyboard is rarely difficult, but you’ll usually need to perform minor surgery in order to release it from the palm rest and carefully unclip the delicate ribbon cable that connects it to the motherboard.

 After familiarising yourself with the location of your memory modules, it’s time to find out what kind of RAM your machine supports, as well as the maximum module density it can accept. If your laptop is a fairly popular model, a nice and easy way of doing his is to select your model in the drop-down menus found on a memory reseller’s website like www.memoryc.com . A quick visit to the latter and the selection of model number ‘MS-1727’ revealed that our machine supports DDR3 SO-DIMMS of either PC3-10600 or DDR3 PC3-8500 speeds.

The maximum density of modules supported is 4GB per DIMM and there are two memory slots. We purchased an 8GB kit from Crucial, which guarantees compatibility or your money back. Interestingly, while the i5 chip currently in the machine supports a maximum of 8GB, the i7 we’re planning to install in a later project supports 16GB according to the Intel spec, giving us further capacity to  upgrade in the future.

Step 1. Remove the cover

Accessing the memory slots on the MSI GX 740 could hardly be easier.

1.You simply remove five small screws from the underside, freeing up alarge access panel, allowing entry to the interior of the machine. 

2.Not all of these screws are necessarily the same size when removing panels  from laptops, however, so take note of which one goes where.

Step 2. Unclip existing memory modules

Removing memory modules, regardless of their type, will involve the same process.

1.You simply use a thumbnail to separate the module  from the metal clip that keeps it clamped down.

2. Do this for both sides of the module and it will pop up at 45º.

 3.To remove the module, you  then simply pull it out at that angle.

Step 3. Install new memory modules

Installing the new memory modules is equally simple.

1.First of all, take care to check the memory is aligned properly. There’s an off-centre  notch in the memory module’s contacts that needs to line up with a corresponding protrusion in the slot. This is there to stop you from  installing the modules upside down.

2. Push the module into the slot as far as it will go before pressing it flat, allowing the metal clips toclamp it flush with the motherboard.

3.Give the module a final firm  press into the slot to ensure it’s all the way in.

Step 4. Replace cover

Realign the rear cover of the laptop, ensuring the screw holes lineup, and then return each of the screws you removed earlier into their respective holes.

When removing laptop screws, always make sure you use the correct size of screwdriver.

Do not try to use one that’s too small or too large or you will damage the delicate screw heads and may no longer be able to get them in or out.  

With the cover replaced, flip the laptop over and power it up.

Step 5. Check memory capacity in BIOS

Hopefully your laptop will fire back up and prompt you with the usual POST screen.

1.Press delete or the relevant F key to enter the motherboard setup menu and proceed to the system information screen. It should display the amount of memory on this screen.

 2.You should hopefully see here how much memory is detected by the laptop - in our case 8GB.

3 .Being able to start up the PC and being 100% stable are two very different things, however, so exit the setup screen and boot into Windows.

Step 6. Run Windows memory diagnostic

Once within windows, you can check that it too detects the new  memory. Remember that in order to support more than 4GB of RAM, your laptop must have a 64-bit version of Windows installed.

 Go to the Start menu and type ‘memory’ into the search box.

 The ‘Windows Memory Diagnostic’ should be the first option at the top.

 Run this, and you’ll be prompted to restart and check for problems.

If this test passes successfully, you can be pretty confident that the upgrade has successfully taken.

The more paranoid among you can use Prime 95 or Memtest 86 to perform a more substantial check.
