3G Wireless Reading Device Review

Amazon Kindle.2



Overall I feel that the Kindle is just as good if not better than other E-Books such as the Sony E-Reader and iPhone E-Book Apps, as it doesn’t boast hundreds of different features but gets straight on with the job. With a whole month of battery life its an incredible unit, especially for those who like to have a daily read. Not only can you store up to 3500 books, but, they cost as little as 72pence each!


After reviewing the Archos 101, people were coming to me asking to review the Amazon Kindle! This product was an exclusive to the USA but has since been released to the UK. The more expensive model, which includes a free 3G connection to the Kindle store costs £139 and the Wi-Fi only model costs around £109.


What’s in the Box


The box contains:-


- Power Adapter


- USB 2.0 cable


- Rechargeable Battery


- Quick Start Guide


Amazon Kindle Package


Physically, the device is a little slimmer than its predecessor. Amazon has achieved this by reducing the size and thickness of the bevel and removing the row of number keys from the keyboard. The keyboard itself is a rudimentary affair that is, thankfully, only used during setup and for book searches, other than that I don’t see the need for having it.


Amazon Kindle


The rear mounted speakers are surprisingly effective, though. Page turn buttons are mounted on the left and right, with forward and back replicated on both sides so you can turn pages one handed. This proved to be quite useful, however, after using the iPad and Archos 101, the touchscreen seemed that little bit better, allowing me to slide the page across rather than press the button. The device itself cuts no corners and does exactly what you would expect. The latest Kindle looks almost identical as its predecessor minus the few cosmetic changes.


However, Amazon have tweaked the performance by increasing storage to over 3GB, improving the clarity of the display and increasing the refresh rate for a better experience. The Kindle uses the new E Ink Pearl panel, and it’s just as comfortable on the eyes as words on a page. The Kindle can even be used in direct sunlight without the need to move around for a better/clearer picture. Not that I have used it in direct sunlight as of yet, but I’m sure to be taking it on holiday with me this year!


Specifications


Display Size
6" diagonal


Display Type
E Ink Pearl


Size
7.5" x 4.8" x 0.335"


Weight
8.7 ounces


Storage
3,500 books


Battery Life                                                                                          1 month


The bottom edge of the device sports a volume control and 3.5mm headphone jack along with a micro USB connector for both charging and data transfer. The latest Kindle does not boast a touchscreen feature, nor do Amazon plan on adding this to future releases. I think the Kindle would benefit from touch screen as I find it easier to just flick the screen to change page.


Battery life is quoted at up to one month with wireless turned off. In the real world, however, Amazon encourages you to keep it switched on so you can store the furthest point reached in a book. However, with internal bookmarks I didn’t see the need for leaving the wireless on. A month of battery life is superb! Considering I charge my iPhone every day!


Amazon has clearly been working hard at improving the book buying process. Order a Kindle and, on delivery, you’ll find it’s been automatically linked to the Amazon account used to buy it. Its simple to buy books and there’s plenty of choice, too, with the UK Kindle store now boasting more than 400,000 titles.


At the time of writing, all of the top ten books were available in Kindle form, many of them at an impressive discount. Stephen Fry’s “The Fry Chronicles”, for example, costs £6.54 in its digital version compared with £9.35 in hardback and this despite the fact that eBooks are subject to VAT. The joy of a device like this is being able to download the entire works of Charles Dickens for 72p and hardly notice the difference in storage available. 72p for that many books will save the user a lot in the long run! The buying process is simple! Find the book, then click Buy! Then automatically the book is saved to the Kindle.


Summary


Overall I feel that the Kindle is just as good if not better than other E-Books such as the Sony E-Reader and iPhone E-Book Apps, as it doesn’t boast hundreds of different features but gets straight on with the job. With a whole month of battery life its an incredible unit, especially for those who like to have a daily read. Not only can you store up to 3500 books, but, they cost as little as 72pence each!

Using a USB modem for wireless 3G internet with Ubuntu 10.04 “Lucid Lynx”


Many of these devices contain their own software to work with Windows.
If you use them with a Windows machine, they act like a USB flash key containing the software and will install the necessary drivers.
Once this is done, they switch into a different mode of operation and act like a modem from then on.
This is not required in Ubuntu so we just need to make sure the modem skips that first stage. It’s a very simple fix actually but will involve getting an internet connection through another means first i.e. home internet, wifi at a cafe, a friend’s place etc

Open a Terminal window (under the Applications menu, Accessories).
Type the following to install what you need

sudo apt-get install usb-modeswitch

This will ask you for your password in order to install the software.
Once it is completed, you can just insert the USB modem again and connect using the Network Manager applet near the top right hand corner of the screen.
From here it depends on the internet provider that the USB modem relates to but it should get you a good deal closer to getting it working.

List: Linux Compatible USB Wireless Adapter (WUSB)

A regular question from my mailbag:

I am in the process of up grading my computer. Where can I get a list of the WUSB for Linux?

Wireless USB adapters are pretty popular for desktop and laptop usage in home. It is capable of sending 480 Mbit/s at distances up to 3 meters and 110 Mbit/s at up to 10 meters. Newer N series can work at 270Mbit/s at up to 300 meters. However, 50-100 meters are acceptable ranges. Unfortunately, finding Linux compatible USB wireless adapter is a big challenge due to driver issues. Over a past few years, I've used and installed various USB wireless adapters and created my own small HCL for it. In this quick blog post I will list all working USB wireless adapter.

Buffalo's Wireless-N WLI-UC-G300 compact USB 2.0 adapter is fully compatible with Linux. Currently I'm using this device with Ubuntu Linux 10.4 and it works out of box. No driver installation is required. Simply add your wireless WPA2 password and you will be hooked up to wireless network. The driver in latest version of Ubuntu kernel is broken and you need to install the driver from source code. (Driver Link for RT2870)

Asus USB-N13 802.11n/g/b network adapter supports USB 2.0 wireless and speed up to 300Mbps Wireless data rates. I get superb connection speed upto 270Mbps and it was auto detected by Linux. (Driver Link for RT2870)

Belkin F5D8053 version 3 also works with Linux. It supports USB 2.0 wireless and speed up to 300Mbps at up to 300 meters. I've tested this one with Fedora Linux. (Driver Link for RT2870)

AboCom WU-5204 is another compact adapter which is fully compatible with Linux. It complies with IEEE 802.11n draft 3.0 and IEEE 802.11 b/g standards and works with USB 2.0/1.1. interface. This one worked and detected, however after some time it started to drop traffic for multimedia stuff. If possible avoid this one due to poor performance.

The D-Link RangeBooster NUSB Adapter (DWA-140) is a 802.11n compliant wireless client for your Linux desktop or notebook PC. I've tested this one with Fedora and Debian Linux. Like all other adapter it supports WPA and WPA2 security features. (Driver Link for RT2870)

EW-7718Un complies with 802.11n draft 2.0, the next generation wireless standard. With the advanced MIMO technology, it can support the data transmission rate up to 300Mbps. EW-7718Un stable wireless connection and high bandwidth enable you enjoying the network applications without any interruption with Linux based systems. (Driver Link for RT2870 #2 # 2 link)

TEW-664UB is 300Mbps dual band wireless N USB adapter. It is compliant with IEEE 802.11n standard and backwards compatible with IEEE 802.11g, IEEE 802.11b and IEEE 802.11a devices. It supports both WPA and WPA2 security.

The EZ Connect N 150Mbps Wireless USB2.0 Adapter (SMCWUSBS-N3) enables wireless connectivity to your desktop or notebook computer and provides improved throughput and range while maintaining full backwards compatibility with the Wireless-G (802.11g) and Wireless-B (802.11b) standards.

ZyXEL NWD-211AN and NWD-270N both works with Linux operating systems. It complies with 802.11n (2.4GHz and 5GHz) and backwards compatible with IEEE 802.11a/b/g. It supports wireless security transmission with WPA/WPA2 and 802.1x.

Sparklan WUBR-501 use USB 2.0 interface and speed up to 300Mbps. It support WPA and WPA2 security.

AWLL6090 Wireless 300N USB Adapter delivers speeds up to 300Mbps. This USB adapter is fully backward compatible with 802.11b/g and RoHS compliant.

ConnectGear WU260N Wireless N USB Adapter 802.11n/g/b supports speed upto 300Mbps with USB 2.0 or 1.1 ports. It's also backward compatible with the existing IEEE802.11g and 802.11b standards for existing wireless networks. Both WPA and WPA2 are supported by this device.

Most of the above devices are automatically installed. If not try updating your kernel version. I hope this post will save some time for readers while purchasing USB wireless adapter for Linux operating systems.

The list is for information and ready references only. Please do your own research before purchasing any device listed here.

Ubuntu Linux: Install RT2870 Chipset Based USB Wireless Adapter

This blog post listed Linux Compatible USB wireless adapters. It seems that many new Linux users frequently have problems learning how to install RT2870 driver under Linux. I also received email requesting installation instructions for the same device. This quick tutorial will explains how to install RT2870 based chipset device with WPA2 authentication and TKIP wireless encryption.

The following instructions are tested on:

Ubuntu Linux 10.04.1 LTSKernel - Linux 2.6.32-24-generic-pae i686 (32 bit)WPA2 with Linksys 160N router

The main problem is conflicting driver which are shipped with default kernel. WPA2 is a method of security wireless networking with optional PSK for home users. The default driver only recognizes driver but always failed to join WPA2 based network. The solution is to install RT2870 driver from the vendor site.

Type the following command to black list default drivers:
$ sudo vi /etc/modprobe.d/blacklist.conf
Append the following driver names:

blacklist rt2800usbblacklist rt2x00libblacklist rt2x00usb

Save and close the file. Use the rmmod command to remove current drivers or just reboot the system:
$ sudo modprobe -r driverName
# you need to remove all of the above drivers one by one:
$ sudo modprobe -r rt2800usb
OR simply reboot the systems:
$ sudo reboot

Type the following command to install required packages so that you can compile source code:
$ sudo apt-get install build-essential fakeroot dpkg-dev
Finally, install Linux kernel headers so that you can compile kernel device drivers:
$ sudo apt-get install linux-headers-$(uname -r)

Visit this page and download USB drivers [RT2870USB(RT2870/RT2770)].

Type the following command:
$ tar -jxvf 2010_0709_RT2870_Linux_STA_v2.4.0.1.tar.bz2
$ cd 2010_0709_RT2870_Linux_STA_v2.4.0.1

First, edit config.mk file as follows so that Network Manager can be used to set WPA2 auth info:
$ vi os/linux/config.mk
Set it as follows:

# Support Wpa_SupplicantHAS_WPA_SUPPLICANT=y# Support Native WpaSupplicant for Network MangerHAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

Save and close the file. To compile the driver, enter:
$ make
Sample outputs:

NETGEAR WNDR3700 Review: The Ultimate Wireless Networking Machine

Sometimes, all you need are the basics.  Other times, you need to break out the "big guns."  The NETGEAR WNDR3700?  One of the big guns.


How big, you say?  Gigabit Ethernet.  680 MHz processor.  A robust 16 MB of flash and 64 (!) MB of RAM.  This thing has the power you need, maybe even more than you need, which makes it perfect in my book - and definitely leagues beyond your average cheapie generic router.


This "ultimate networking machine" is also fully decked out with everything the super-connected, bandwidth crunching, HD media streaming home requires, with power to spare.  Is the WNDR3700 right for you and your home?  Read on, and learn about the advanced features of this special router.


NETGEAR WNDR3700 Box


I've unboxed a lot of NETGEAR products, and the WNDR3700's packaging is no different.  NETGEAR does a great job of packaging, keeping the materials efficient, with as little waste as possible, while retaining the product safely and securely.


NETGEAR WNDR3700 Box Contents


Inside the box, you'll find the WNDR3700 router along with the installation CD (you won't really need it,) the power cord,  an Ethernet networking cable, and a stand if you wish to use it.


NETGEAR WNDR3700 Unboxed


The router is handsome, as far as routers go.  It's made of a sturdy plastic with a glossy NETGEAR-logo-embossed top, and looks really sharp.


NETGEAR WNDR3700


The back of the router is gifted with mounting holes, with which you could easily attach the WNDR3700 to a wall - for example, in your basement or in a media center.  Very handy.


NETGEAR WNDR3700 Back Panel


The back ports are pretty standard - except for that the Ethernet ports are gigabit capable, and you also get a USB port for ReadyShare usage (more on that later.)


Ready to get this bad boy up and running?  Fortunately, NETGEAR really makes setup quite easy on this router (as well as all others that I've gotten my hands on.)  This is nice, since router setup can really be a pain, especially with cheaper products.


After plugging in the router to your local network as well as to your Internet connection and powering it on, simply navigate to 192.168.1.1 in your browser bar, and enter the "standard" credentials.  (If you need help connecting the cables, consult your user manual - but for basic purposes, plug the cable from your Internet into the yellow port, and your local network items into one of the four others.)


Admin = admin


Password = password


NETGEAR WNDR3700 Update


Pretty simple.  You'll be brought into the router interface, at which time it will check the NETGEAR servers for a newer version of the firmware.  You should allow it to do this, and complete an update if necessary.  Having the newest version of the stock firmware ensures that the device will be stable and have the latest feature set.

List: Linux Compatible USB Wireless Adapter (WUSB)

A regular question from my mailbag:

I am in the process of up grading my computer. Where can I get a list of the WUSB for Linux?

Wireless USB adapters are pretty popular for desktop and laptop usage in home. It is capable of sending 480 Mbit/s at distances up to 3 meters and 110 Mbit/s at up to 10 meters.

Over a past few years, I've used and installed various USB wireless adapters and created my own small HCL for it. In this quick blog post I will list all working USB wireless adapter.
