Does WEP/WPA slow down wireless connections ?

Yes, WEP and WPA encryption add some overhead in terms of calculations needed to encrypt/decrypt the traffic. The exact impact greatly depends on the processing power of the network device, it can vary from 5% to 30% of the maximum throughput.

With newer routers that have faster processors, enabling WEP/WPA should not have a major impacts on performance, it should be barely noticeable at full load. Some older models, however, can slow down as much as 30% or more due to the added processing overhead.

Even though there is some perfomance impact, it is not noticeable in newer devices, and the benefits (security) far outweigh any drawbacks.

Note that WPA2 (AES), in addition to being more secure is also much more efficient than WEP/WPA(TKIP) and should be used, if possible.


Comment :
How much do WEP or WPA/WPA2 encryption hurt wireless performance? i understand that it varies from router to router, newer ones having nearly zero impact, but some having up to 25%. mine is somewhat oldish (3 years maybe?), its a D-link DI-524. just curious.

How to run Android on Windows Mobile Phone

Install Android on your HTC Windows Mobile phone – Guide

Welcome to the official XDANDROID AOSP thread which is dedicated to getting Android running on our beloved HTC devices.
Phhusson: has dedicated most of his time helping users and updating kernel to run Eclair and his work for other msm7k devices. However phhusson is not alone as there are also other members working on this. You can find some of them on I've listed some of the developers i know of that currently are working on and they deserve credits and thanks. We also have to note that before this work done there was quite a substantial number of people starting working on linux for our devices. Without them we may not be where we are today. So respect and credits to everyone involved in working on linux kernel for msm devices.
I am not responsible for any damages or problems your device encounters. The build is relatively safe and shouldn't cause any problems.

Apple threatened to ban Uber

Apple CEO Tim Cook threatened to remove Uber from the App Store in early 2015, amid revelations that the ride sharing service had violated iOS privacy rules, according to the New York Times. Uber had reportedly assigned permanent IDs to iPhones, allowing the company to track users even after the Uber app was deleted or an iPhone was wiped.

Controversial tech exec Travis Kalanick was forced into a face-off with Tim Cook, a new profile of the Uber founder claims, after Apple discovered the ridesharing app had flouted privacy rules. Kalanick’s company has repeatedly made headlines over the past year for a number of reasons, ranging from frustrated drivers, arguments with city administrators and legacy cab firms, over-ambitious autonomous car testing, and allegations of harassment in the workplace. Indeed, Kalanick’s ambition almost saw him lose his entire iPhone audience. The degree to which Kalanick was willing to push his company to the brink is made clear in a new profile of the entre…

How to Remove Windows Genuine Advantage Notifications

Windows Genuine Advantage (WGA) notifications occur when your computer hasn't passed the validation test. The validation test can be failed due to being sold a pirated (non-genuine) copy of XP, or because you have changed your XP product key to a software-generated key, or sometimes it just happens for no reason at all. The failed validation installs three types of notifications on your computer: one on the log in screen, one log in timer, and one balloon. It also stops updates from Microsoft and disables your ability to install IE7 and Windows Media Player 11. This solution can get rid of all three notifications, even though you will still not be able to update through Windows Update. You will not be able to download things from Microsoft that requires a valid license either. EditSteps
Delete Method 1 If you have only just installed Windows Genuine Advantage notifications, simply using the system restore function will remove the program. Then refuse to accept the WGA update next tim…
