3 Things You Must Know To Get Started With Wireless Internet Service

January 23rd, 2013 No comments

It is one thing to take a decision that you will switch from your conventional home cable connection
and Wi-Fi setup to the more advanced mobile internet connectivity and it’s a complete different thing
to actually get started using this new technology from scratch. This is why it is recommended that you
have a clear idea about the starting blocks of the mobile internet connectivity technology and ensure
that you seek help from your service provider at the sign of any problem.

Here are the top and most important 3 things about starting off using a mobile wireless internet
connectivity that you need to know in order to make your experience of transition a hassle-free one –

1. Getting Connected

When you have subscribed to a plan with the service provider of wireless mobile internet
connectivity of your choice, you will most probably be having the necessary device and
login credentials with you. In case you don’t have it, then you need not worry. Your service
provider will call you up with a convenient time for you to setup the connection once your
order has been processed and approved.

Remember to check with the service provider about any terms of usage that might be there
for the device for the mobile internet connectivity. Also check to see that all necessary
documentations of the device and the driver media are provided with the device. Many
service providers will also provide a wireless Wi-Fi router for your device in order to enable
you to get the internet connection on multiple devices simultaneously.

2. The Devices For The Connection

Once you have the necessary devices you will need to install the same with the computer.
Connect the device and wait for the computer to recognize the same. Once it has recognized
the device, it will ask for the driver media which you will need to insert for installation of the
driver and the service provider’s software. Once done with these, you are all set to go.

There are various ways in which you can pay for your device, both the USB dongle come
antenna for connecting to the internet and the Wi-Fi router that your service provider provides
along with the package. You might need to pay an initial one time refundable security deposit
for these devices or you might be required to purchase the same from the service provider or
buy your own from a shop. Some service providers like clear internet promotions offer the
device free of any additional cost.

3. Range And Security Of The Devices

Remember that any form of wireless or Wi-Fi device, no matter how strong it is comes with
a range beyond which it will be unable to transmit any data and provide internet connectivity.
You will need to ensure that you take care of this aspect of the router when setting it up in
your home. Also ensure that you have a secure password protecting your internet connection
from unauthorized intrusion.

With these 3 aspects of the getting started of wireless mobile internet connectivity taken care of, you
can rest assured of a good time!

Steps to Securing Your Wireless

December 21st, 2009 1 comment

Many have wireless network in their homes. The freedom from tangled cables is sweet but comes with a price. A wireless network can broadcast far outside your building. With a powerful antenna and some widely available hacking software, anyone sitting near your installation—or even driving by—can passively scan all the data flowing in your network.

Keeping your wireless network secure is no small task, but there are precautions you can take to secure your network as much as possible. The following are some steps you can take to best secure your wireless network. Here are 13 steps to lockdown your AP (access point) and make your wireless network more secure.

  1. Admin users and passwords – Many people don’t bother changing the default settings admin user and password. This makes your system an easy target. Change default username and passwords. Also use extremely long, random password consisting of letters, number and symbols.
  2. Encryption – Every computer on your network should be configured with best security in mind. Make sure that all networking devices support the latest and most secure encryption standards. Look for devices that support WPA or WPA-2 or at least use Use 128-bit WEP. 64-bit WEP is unsecure and has been exploited as far back as 2001. If you use WEP encryption, change your encryption key once a month. If someone manages to learn your key, they will be locked out again when you change it.
  3. Disable SSID Broadcast – Change the default Service Set Identifiers (SSIDs) for your access point. If you have to use SSID then use something less generic such as ‘linksys’. Don’t use anything obvious like your name or phone number. You’re probably better off disabling SSID broadcast all together.
  4. Filter MAC addresses – If there are only a handful of people that need wireless access, then Only allow authorized MAC addresses that you identify should have access to your network. MAC addresses can be spoofed, but it would take more effort for someone to try to spoof your MAC address.
  5. Limit IP address assignment – Limit the number of IPs that should connect to your network. If you don’t have too many users, consider limiting the maximum number of DHCP addresses the network can assign, allowing just enough to cover the users you have.
  6. Upgrade/Updates – Always make sure you have latest firmware recommended by vendor. Sometimes exploits come out that target devices with older firmwares.
  7. Disable DHCP – The presence of DHCP is one of the major reasons why wireless networks are so insecure. Any computer that is able to communicate with your router will receive an IP address automatically, and this address will put it on the same network as all of your systems, enabling it to instantly access any unprotected resources on your network such as shares. Therefore, disable DHCP and use static IP assignment to make your network a bit more secure.
  8. Do Not Auto-Connect to Open Wi-Fi Networks – Don’t connect to unprotected wireless networks—it’s possible for someone to monitor your Internet usage and even record your passwords. If you do connect to an unprotected wireless network, don’t visit a Web site that requires a password unless the Web site is encrypted. To find out if it’s encrypted, look for a lock symbol in the lower-right corner of your browser.
  9. Enable Firewall – Modern routers contain built-in firewall capability, but the option exists to disable them. Ensure that your router’s firewall is turned on. Additionally, consider installing and running personal firewall software on each computer connected to the router for extra protection.
  10. Position the Router or Access Point Safely – Wi-Fi signals normally reach to the exterior of a home. A small amount of “leakage” outdoors is not a problem, but the further this signal reaches, the easier it is for others to detect and exploit. Wi-Fi signals often reach through neighboring homes and into streets, for example. When installing a wireless home network, the position of the access point or router determines its reach. Try to position these devices near the center of the home rather than near windows to minimize leakage.
  11. Turn Off the Network – Shutting down the network will most certainly prevent outside hackers from breaking in. If you’re taking a long vacation or not going to be home for sometime, consider turning it off.
  12. Use RADIUS – Installing a RADIUS server provides another authentication method. The servers tend to be expensive, but there are open-source options, such as FreeRADIUS (, for UNIX-savvy administrators.
  13. Disable remote administration – Most WLAN routers have the ability to be remotely administered via the Internet. Ideally, you should use this feature only if it lets you define a specific IP address or limited range of addresses that will be able to access the router. Otherwise, almost anyone anywhere could potentially find and access your router. As a rule, unless you absolutely need this capability, it’s best to keep remote administration turned off.
  14. Don’t use it– Uhmm. I saved the best and most secure one for last. Just don’t use wireless and you’ll be safe 🙂

There are many other precautions you can take to make your wireless network and internet browsing secure. The most important thing to remember is that you’re never 100% secure but you can always stay on top of latest techniques used by hackers against wireless networking. Read our previous article Linux Wireless Network Detectors and Sniffers and put the steps you’ve implemented above into test.

It would be interesting to test prior to implementing the steps above and then retest after you’ve implemented all the steps we’ve mentioned above. You’ll be amazed how much more secure your network is now.
