How to Extend Wi-Fi Coverage and Eliminate Dead Zones


M
ost users having a wireless router at home or office usually complain of dead zones and low wireless connectivity in certain areas. This usually happens when you have a large room or multiple rooms, where a single wireless router cannot serve the entire area effectively. Upgrading to Wi-Fi ‘n’ routers or installing high-gain antennas could solve the problem, but the chances are remote when it comes to accessing the signals in a larger area or if you have many walls in between you and your router, especially. Adding Wi-fi signal repeaters can help, but this increases the overall cost of the hardware. 

A simpler and slightly cheaper solution would be installing additional wireless routers in other rooms, which will solve the problem. In this workshop, we show you how to configure multiple routers on the same network. Using this trick, you can have one single SSID throughout the entire network and stay in the same subnet too. Before you proceed, make sure you have an extra router handy with you. Any basic router would do since the goal is to spread the Wi-Fi network to a specific part of the house and not the whole house. You can invest in a few cheap Wi-Fi ‘g’ or ‘n’ routers, depending on how big your house is.

Choosing the right channel is very important

Let’s begin with an example to make you understand the network a bit better. You have a large home, which spreads across two or more rooms or floors. You have one wireless router, which is connected to the Internet gateway (either a DSL modem or a direct connection through your cable guy) and is placed in your living room. You can access this wireless network in your living room with ease, but your bedroom, kitchen, terrace or garden area has a very weak signal or you are unable to even get the network there. All you need is an additional router or more routers, which will pick up the primary network from another room and extend it further into its area. We shall take an example of a scenario where three routers are required to cover the area in the living room, the bedroom and the garden. Let’s call the primary wireless router in the living room as LR1, BR1 for the wireless router in the bedroom and GR1 for the one in the garden. Now we assume that LR1 is configured by default with SSID ‘RAHUL’ and a secure WPA2 password.

Let’s assume IP address is 192.168.0.1 and the DHCP server is enabled.  All clients now connecting to this router will be given IP addresses by this DHCP server on LR1 from 192.168.0.2, 192.168.0.3, and so on. Log in to your router using that IP in a browser and open the settings page.  Here, set the wireless network channel to ‘Channel 1’. Now, dig around a bit till you find the option to increase the antenna gain, and set it to the highest possible strength. Save and restart the router. LR1 is now configured.

Now let’s configure the second router BR1, which is placed in the bedroom. Once again, connect the router to a PC via the Ethernet or Wi-Fi network for configuration. Open the setup page of the router and start the setup wizard. Configure the WAN IP (Internet gateway) settings as ‘Dynamic’. This will receive an IP address from the primary router automatically. Next move on to configure the wireless network details, such as SSID and security password. Now enter the SSID the same as the primary router LR1 (in this case ‘RAHUL’). Enter the security type (in this case WPA2) and password, which is again identical to LR1. Next, set the channel number as channel 6, so that there is no overlapping of the channels between LR1 and BR1. Increase the antennal signal strength to maximum. Next, move on to the LAN settings and disable the DHCP server. Save the settings and the router will restart. Now BR1 is also configured.

Microsoft Office 2013 First Impressions





Microsoft Corp.'s CEO Steve Ballmer recently unveiled the customer preview of the new Microsoft Office, optimised for Windows 8 and touch-based devices like tablets. This release features an intuitive design that works beautifully either with touch, stylus, mouse or keyboard across new Windows devices. The new Office is social and unlocks modern scenarios in reading, note-taking, meetings and communications, and will be delivered to subscribers through a cloud service. We decided to give it a quick try and here are our initial impressions on the widely used applications that form Office 2013.

Aesthetics and UI enhancements



Office 2013 is slick and buttery smooth. There hasn't been much change to the UI, with the same ribbons, options and enhancements still there, but there are a ton of new features that we have individually covered below. However, the overall aesthetics and user interface of this new version is simply beautiful – from the smooth refresh rate for the cursor and the lag-free, fluid scrolling to neat little subtle animations, everything feels buttery. The colour styles are well chosen, giving this new Office a very minimalistic yet professional look. Let’s have a look at the individual applications below. 



Word 2013



Images in Word now come with live layout and alignment. What this indicates is that if you add an image to your text and move it around the page, your text automatically aligns itself based on where the image is placed, in real time. You also have a simple mark-up view that provides you with a clean, uncomplicated view of your document, but you still see markers where changes and comments have been made. You can click on the vertical bar on the left side of the text to see the changes. Or click the comment icon on the right to check out comments about the text. The read mode has got a neat little trick – all images can be expanded from the read view itself, giving you a uniform read in a single window.

Users can also add and play online videos inside their Word documents. You can also add pictures from Facebook, Flickr, and other online photo services without having to save them to your computer. Click Insert > Online Video to add a video to the document.


Image-only PDFs didn’t have as many editing options like we have seen with free online software, but PDFs with texts are now easy to edit and save. We’re not sure if this is a good thing, though; editing PDFs was always known to be a complicated process and this may just be an easy way out for those wanting to make changes in their PDF files. 


Excel 2013 



Flash filling your data is now a part of Excel 2013. It’s really helpful for those working with insanely large numbers of spreadsheets with similar actions for particular rows and columns. For example, you start typing the first names of your email IDs which are in column 1 and the rest of the names are added automatically. Simple, yet saves a lot of time. 


Excel 2013


You can analyze data using live previews and Excel gives you a quick analytical chart in the column itself, showing you the differences between the different values. A recommended chart option in the Insert tab lets Excel recommend you charts based on the data you have entered. The look and feel of Excel may not be a complete overhaul from previous versions, but why fix something that’s not broken? With the new subtle animations and smooth transitions, the experience with Excel 2013 makes us like it even more.
