Tech problem of the week - MAC address filtering
Why you need to know
If you have noticed your wireless network speed slowing down, it is possible that too many devices are connected to it. Even though a password is on the router, persons still find a way to connect to the network to access the Internet. Opening the router's system information and resetting name and password will result in the wireless connection being lost from the intruder's device indefinitely. That is, the device will never be able to reconnect.
What you will need
A computer (currently connected to the router)
Wireless router and connection
How to get it done
1. Open the browser or a new tab.
2. In the address bar of the tab type the Internet Protocol (IP) address '192.168.0.1'. The standard IP address for most routers.
3. The router's system settings page should appear (see the image). For this example and Arris router, type in the username and password, which could be a login combination of Admin/Password, Admin/Admin or Password/Password respectively.
4. Go to 'Wireless Setup', select from the options listed 'Wireless Client List' to see which devices are connected. Any unknown devices will appear as well, including details on the IP address and Media Access Control (MAC) addresses.
5. Note which of the devices you want to remove from the router, which is known as blacklisting, and record the MAC address on a piece of paper or the computer's notepad. Go to 'MAC Address Control' also within 'Wireless Setup'.
6. Two options will appear, 'MAC Address Filtering' and 'MAC Address Filter List'. Click on 'Add' and the option to enter the MAC Address of a device will pop up in a window. Type in the address as seen in the 'Wireless Client List'.
7. Then in the 'MAC Address Filtering' type, select from 'None', 'Whitelist', or 'Blacklist'; in this case, 'Blacklist' and then click on 'Apply'. This device will only be able to connect if the MAC address is selected for the 'None' or 'Whitelist' filter option from then on.
Apps this Week for Android, Apple and windows
CamScanner for Android
The CamScanner application is highly recommended for persons who are frequently attending presentations. It allows users to digitise a wide range of documents by using the smartphone's camera to capture an image and transform it into a PDF document and a JPEG image separately. It is a free application; however, some features may be unavailable and user reviews vary as it relates to the sharing option. It is best to purchase the application if it's going to be used to create documents for sharing with professionals.
The smart-processing enhancements will auto-detect the edges of the document or whiteboard and adjust brightness. The extract text features allow the user to copy and edit text for searching and editing purposes. CamScanner also has built-in integration with whichever cloud-storage app or account installed on the smartphone device and synchronises with other user devices.
Genius Scan for Apple (iPhone)
Genius Scan has a wide range of sharing options once the documents or images are scanned, files are exported as JPEG and/or multi-page PDF documents. It is integrated with social networking applications for easy sharing on Twitter and Facebook. The documents are also organised by titles or user tags. For individuals with the Expensify app installed, receipts scanned through Genius Scan may be sent directly to the app to create expense reports, thus eliminating any manual input. While the app is free, users will experience advertisements and pop-ups; the advertisement-free version is available at a price.
Office Lens for Windows
Office Lens is an amazing productivity tool for Windows phones. Though it is fairly new and users may experience a few glitches, the Microsoft developers are quick to respond to users' concerns and reviews so as to improve the application. It is the best way to scan on the go; in 'Whiteboard Mode' the Office Lens scans the whiteboard, trims the edges and cleans up glares and shadows to let the image appear like a digital document. In 'Document Mode', the app acts similarly with additional colour adjustment. The application only recognises notes in English for the search tool at the moment but once the document is scanned, Office Lens will convert and save into OneNote for view.
The red, pink Huawei Ascend Y330
These days it's a given to have a phone that's able to use WhatsApp, Facebook, and Twitter if you're into that stuff. The Huawei Y330 is a great mid-range Android phone that is here to corner the market with an aggressive price point. So aggressive that it might be the new Nokia flashlight phone trend for LIME customers.
What makes this phone tick?
The fact that it was stated mid-range phone should give you the clue that you shouldn't expect anything close to a Samsung Galaxy S5 specification, but that doesn't make it a horrible phone.
Display - 4.0 inches (~245 ppi pixel density)
Memory card slot microSD, up to 32 GB
Internal storage 4 GB, 512 MB RAM
Bluetooth v4.0, A2DP
Camera - 3.15 megapixel
Android OS - v4.2 (Jelly Bean)
CPU - dual-core 1.3 GHz
Sensors - accelerometer, proximity
FM radio with RDS
A phone without a camera is considered antique these days and thus won't sell or attract the masses. The Y330 wants to be sold and the outstanding 3MP camera on the back takes lovely photos in the days. There is no flash to help take pictures in low-light conditions, but it still produces attractive low-light photos. One minor problem I had with this phone was that absence of a front-facing camera.
Processor and Memory
This phone comes with a dual core 1.3GHz processor that is actually powerful enough to run most of the apps on the Google Play Store. The 512MB of RAM that the Huawei Y330 has is small compared to the top-of-the-line smartphones out there, but it gets the job done. Although, you should expect some slowdown in the operating system while running more than two applications in the background at a time. If you are a newcomer to Smartphones then this won't be a problem, you'll probably want to do one task at a time until you figure out the phone's full potential.
Although this phone doesn't offer a large battery, it has built-in apps to maximise the most of what it has to work with. The power-saving options will show applications that are installed and using up most of the phone resources. Also, the fact that this phone isn't quad- or octa-core makes it very easy to last an entire day on a full charge. It offers up to 5 hours of talk time, and 320 hours on standby, which is average for most smartphones on the market.
The options for a smartphone that cost below the $9,000 mark are limited or non-existent in most cases, but the Huawei Ascend Y330 is the perfect solution for persons looking to enter the new age of phone tech without putting too much of a dent in their finances.
