WiFi goes to Limited

WiFi goes to Limited

Windows 8 RaviTeja   6:05:00 PM

We can see that our WiFi connection goes to limited connectivity sometimes. Its annoying in case of urgency.
Here is the solution for Windows !

Step 1 : Open Network and Sharing center
Step 2 : Click on the WiFi connection
Step 3 : Goto Properties
Step 4 : Click on 'Configure' without selecting anything.
Step 5 : Goto power management tab in the appeared box.
Step 6 : Un check the box which says "Allow the computer to turn off this device to save power"
Step 7 : Click OK and close Network and Sharing Center
Step 8 : Open Command Prompt (cmd)
Step 9 : Type ipconfig /all
Step 10:Type ipconfig /release
Step 11:Type ipconfig /renew
Step 12: Close the command prompt.

The above process should solve your problem. If this doesn't contact network administrator or router manufacturer.

Types of Wi-Fi Encryption You Can Use

Types of Wi-Fi Encryption You Can Use

Wi-Fi RaviTeja   12:51:00 PM

There are many types of Wi-Fi encryption you can use on modern Internet routers. So which one should you use? Many people don’t even use encryption, and those that do just pick an encryption type at random without knowing what they do.

For a long time, WEP was considered to be an extremely good method of encrypting wireless connections. The acronym simply means Wired Equivalent Privacy. WEP however, was proved to have many flaws mainly involving the short key size, which were relatively easy to crack. WEP also does not provide for security against altered packets – a process where packets of information is intercepted by an intruder and then altered before sending them back, making it look like the intruder is valid user. These days, WPA (Wi-Fi Protected Access) and WPA2 have completely taken over from the old WEP encryption methods. You’ll probably still find WEP available on most routers, but it’s being phased out and someday it probably won’t be available at all. The main advantage WPA has over WEP is that it employs a powerful new feature called TKIP, or rather Temporal Key Integrity Protocol. TKIP is 128-bit, but instead of the key being static, it generates a new key for every packet of information that is sent, meaning it is a lot more secure. WPA also integrates a method of message integrity checks, used to defeat network attackers intercepting and altering data packets. WPA2 goes even further and replaces TKIP with CCMP. CCMP is an AES based encryption method that is much stronger even than TKIP.
In the home, you’ll probably want to use an encryption method called WPA-Personal. This is sometimes also called WPA-PSK. PSK stands for Pre-Shared Key, and is designed for home users and small offices where a server is not required for authenticating messages. It works by having each wireless device such as a laptop or smart phone authenticating directly with the wireless access point using the same key. Offices and large buildings may employ WPA-Enterprise. You can’t generally use this without a complicated authentication server set-up, but it does provide additional security.
Both WPA-SPK and WPA-Enterprise are available in WPA2, meaning even home users can now benefit from AES encryption over their Wi-Fi connections. All of these methods can transmit data at maximum speed, and you won’t notice any speed differences between each type of encryption. Therefore the recommendation is to use the best encryption you can. This means going for WPA2-PSK where you can in a home environment. There are new and more exotic types of Wi-Fi encryption becoming available, but for now even advanced users will find WPA2 more than adequate for most security applications.
If you are using wireless connections, you may want to check your router to make sure that it does not use encryption that can easily be cracked by users with the right toolset.

Wireless Tether Turns Your Phone into a Wi-Fi Hotspot

Wireless Tether Turns Your Phone into a Wi-Fi Hotspot

Wi-Fi RaviTeja   8:48:00 AM

Finally, Wireless Tether. For many users, this feature is the single most important thing in the world of mobile devices, so having the ability to use it is a must. Wireless Tether turns an Android phone, regardless of carrier, into a full blown W-Fi hotspot for any nearby devices that need one. It's as simple as that, but only rooted phones can use it.

*** If you get force closes after the update uninstall and install it again! ***
This program enables wifi AND bluetooth-tethering (PAN) for "rooted" handsets.
Clients (your laptop for example) can connect via wifi or bluetooth and get access to the internet using the mobile connection (4G, 3G, 2G) or (in case you are using bluetooth) the wifi connection which is established by the handset.
Wifi-tethering creates a so called adhoc (peer-to-peer) network on most devices. Infrastructure-mode is suppported for some devices – including the HTC Evo for instance.

** FEATURES **
-) Access-control feature. Allow/deny clients to use your mobile-data connection.
-) Wifi-Encrytion. 128-bit WEP in general. WPA/WPA2 on supported devices.
-) Reduce wifi-transmit power (on supported devices)
-) Settings for wifi-ssid, wifi-channel, „lan“-network and more.

This application requires a "rooted"-device and a (custom-) kernel which supports netfilter (iptables)!
** PREREQUISITE **
1) Root
2) Netfilter-enabled kernel

Use this application at your own risk. It is possible that use of this program may violate your carrier's Terms of Service.
