Sprint Overdrive 3G/4G Mobile Hotspot by Sierra Wireless

Sprint offer a wireless hotspot device for their 3g and 4g networks. I took a device on evaluation from Sprint recently and tested how well it worked at my home. My address is not listed as supported for Clearwire wireless internet, which is the same network as the Sprint 4g devices use. So I was interested to see how well it would work.

AT&T DSL Speeds - Click to Enlarge

First I tested the speed of my AT&T DSL broadband as a comparison between wireless and land-line capability. My DSL is marginal where I live (which seems to apply to any service I have looked into). DSL Download/Upload speeds achieved were 2.35 Mb down and 0.32 Mb up. Pretty pedestrian by today’s broadband offerings and demands from services such as Netflix streaming.

I then switched on the Sprint Hotspot device. It sync’d using 3g only. Power cycling didn’t encourage it to connect to 4g at all. Maybe my home is just too far out. The speeds I got with Sprint 3g are 0.33 Mb Down and 0.24 Mb Up. Very slow indeed. I got much better speeds using my Droid as a tethered modem using Verizon wireless 3g network.

Perturbed by the very slow speeds I decided read the manual and discovered where the factory reset button is. Being an eval unit someone ahead of me may have set some weird and wonderful setting. After a successful reset and reboot the device immediately connected to the 4G network. I checked the firmware, it is up to date, all it needed was a factory reset.

The signal strength varied between 20% and 40%, so my address is clearly marginal for Sprint. I tested the performance and got 4.92 Mbs Down and 0.92 Mbs Up. Much better and superior to my AT&T DSL. This is fast enough to support HD quality movie streaming from Netflix and others. I am due to get uVerse installed in a few days so will update this post with those speeds as a direct comparison.

The hotspot device can be used as a Wifi hotspot supporting up to 5 clients, or as a tethered device. The management console is clear and easy to use. I was able to change from WEP encryption to WPA2 easily enough, the unit rebooted after this change and worked just fine.

I switched on GPS location to see how that would work. The unit consistently failed to get a GPS lock inside my home. My Motorola Droid never has issues, so the GPS sensitivity for this device seems poor.

The device looks like a hockey puck, is reasonably light and is easily thrown into a laptop bag. It uses a universal Micro USB charger, so you don’t need to carry its charging cable/wall plug if you already have one for your phone or other device(s). As standard the device comes with a quick start guide. To get the full manual, one needs to download this from Sprints support website.

Compared to Verizon wireless LTE, the Sprint network is a step behind in terms of raw speed. Reports of 10Mb down and 3 Mb up on Verizon LTE hotspots reveal that the Verizon 4g is a step above the older Sprint/Clearwire 4g. Speed isn’t everything though. Verizon put a 10GB monthly cap on their hotspot devices, Sprint’s claim to fame is that their unlimited means truly unlimited. So if you want to stream Netflix movies and therefore consume large amounts of bandwidth, the Spring hotspot device makes better financial sense.

If AT&T U-verse disappoints, I will seriously consider a Clearwire modem or this 4g hotspot from Sprint. As much as I like LTE from Verizon and already being  a Verizon customer, the 10GB cap would be way too restrictive for my home internet needs. Sprint have made the right choice in not placing caps on their wireless service, no one wants an unexpected bill at the end of the month because you used ‘too much’ bandwidth. 10GB is hardly classifiable as hogging bandwidth in this day and age. A 10GB cap on a individual smartphone sounds OK, but on a  hot spot, it’s outlandish. Congratulations to Sprint for getting this right, shame on Verizon.





Nissan LEAF Test Drive

On March 26th 2011 Nissan held a test drive event for their all electric car, the Nissan LEAF at Franklin TN.

The Event

This was a source of disappointment. Nissan set up a series of tents on the Parking lot of their Headquarters in Franklin TN. It was a cold and damp day and the tents had no form of heat. Punters had to be content wearing multiple layers of clothes as they listened to a sales pitch and lined up to drive the LEAF’s. I had a 1pm appointment time scheduled. Other than quick registration, the appointment didn’t assure you of a  place in line or any priority, one lined up with walk-ins. The ‘refreshment’ lounge consisted of a cup of instant coffee and a packet of cheez-its. It made me feel the event was done on a tight budget. The guy delivering information about the car and the logistics of the event was both upbeat and informative. He was the only spark of life I saw that day.

I am on the list of 20,000 people who have first refusal on a  new vehicle. I have not taken advantage of this since I would never buy a  vehicle without seeing it in person and have a test drive. I also Read the rest of this entry »

How to register an orphaned AT&T 92370 handset to a different base station

9 03 2011
AT&T TL92370 Phone System

AT&T TL92370 Phone System

Lightening recently damaged my AT&T Home Telephone Answering system base station rendering the 3 cordless handsets useless. I purchased an identical Telephone system that comes with 3 handsets and hoped to reuse the handsets fom the old system on the new.

Problem

The AT&T TL92370 base station can support up to 12 handsets. However as I read through the instructions on registering and deregistering handsets, it became apparent that to deregister a handset from the base station one needed a working base station to do so. The handsets once registered to a base station cannot be registered to another until they have been released from the original base station. The orphaned handsets displayed the following message

Out of range OR No power at base

I searched in vain on the net looking for a way to remedy this. I diassembled one of the hansets hoping to find a reset switch. No such luck. I was now the proud owner of 3 orphaned handsets I could not use.

Resolution

I sent an email to AT&T asking how to accomplish this. I got a boilerplate response informing me that my problem was too complicated for email resolution and to call 1-888-883-2442 to speak to a tech. I called using Skype. It took about 8 minutes on hold before I got through to a live tech. He asked basic questions and did understand my problem first time. He put me on hold and came back with the folowing code to enter into the old handsets.

*331734# followed by menu/select

The phone beeps twice, reboots and then comes back up ready to register to a new base station.

Registering to the new base station is now easily accomplished using the standard instructions.

  • Press and hold handset locator on base station until ‘in use’ light comes on.
  • Press # on the handset and the phone registers itself to the base station.

I repeated the above procedure with my two remaining handsets and now I have a 6 handset cordless system for my home.

It’s important to note that if you have a working base station you should use the standard instructions for deregistering the handsets. Each handset gets allocated a handset number by the base station, if you deregister using the special code detailed in this post then the reserved handset number on the base station is consumed and cannot be reclaimed; thus reducing the number of handsets the base station can support by 1. The special code is only for use when you have a handset that is orphaned from a lost or  non-working base station.





Fixing a broken Grub2 Bootloader after hard drive upgrade

13 11 2010

I recently replaced the hard drive in my laptop. I used Acronis True Image Home 2011 to clone the old hard drive to the new one. It increased the sizes of the partitions proportionatly and made the drive bootable. So far so good.

In addition to Windows 7 I have Ubuntu 10.10 dual booted using Grub2.

Windows 7 booted just fine after the upgrade but Ubuntu would not boot and dropped into busybox with the following error

/dev/disk/by-uuid/xxxx does not exist
dropping to shell

Where xxxx is a long number called a UUID

Because the Linux partition was now 20GB larger than before it had a new UUID which did not match what Ubuntu expected.  Since the introduction of Grub2 Ubuntu boots using Read the rest of this entry »





Pre-Release version of Kindle 3 software available

21 09 2010

Amazon have posted a preview version of a software update for the Kindle latest generation. The software is available for a limited time. If you intend to update be sure to download before it is removed

The release fixes several issues including

  • Slow web-browsing
  • Slow page turns in bright sunlight.

I find it ironic that page turns with the current Kindle 3 are slower in bright sunlight, especially after Amazon’s latest TV ad poking fun at the iPad’s readability in bright sunlight. I’m sure they will release the software update as soon as possible to save getting too much egg on their face regarding the sunlight issue. I believe their TV Ad campaign is flawed, read more here.

New Kindle Owner – Week 1

19 09 2010

I placed my order for the latest Kindle 3 with Wifi + 3g on September 3rd 2010 and it arrived a few weeks later on September 16th. I’ve used it for a few days now and here are my first impressions :-

The Unexpected

Being sold out and on back order I resigned myself to having to wait 2 weeks to get the device before I could use it. However as I read up on the Kindle I quickly discovered you don’t actually need a Kindle at all to read Kindle books. Amazon have released Kindle applications for computers and smart phones. Visit this web page for more details.

I was able to install the Kindle app on my Android phone and start downloading and reading Kindle books immediately.  You don’t need to have ordered a Kindle to do this, the software is freely available.

I read HG Wells War of the Worlds. I had seen the TV reenactment of the famous radio version of this story. The book however was both different and delightful. Quite a satisfying read. I was amazed how readable the book was on an Android phone. I had read the entire book while waiting on the Kindle to arrive in the mail. I found the ‘Sepia’ theme to be the easiest on the eyes. I also experimented with the Desktop application on both Windows XP and Windows 7. It worked great and synchronized my reading place between devices across the internet. Amazon refer to this sync feature as WhisperSync. It works remarkably well.

I also discovered that many classic books are free, and some books are offered for free on short term promotions. Many books offer the first chapter for free.

By the end of the first week I had purchased 17 books. 15 free, 2 paid for, for a grand total of $10. I had registered 2 mobile devices and 4 computers to my Amazon account in addition to the yet to be received Kindle.

The Good

The Kindle arrived and I found the reading experience to be much better than anticipated, even given the positive reviews I had already read on the web. The text is very sharp thanks to great contrast. This is my first time to experience ‘e-ink’ and it is quite phenomenal. In bright light I find the readability to be superior to physical books.

Not only were all my purchases available directly upon opening of the box, but all my Audible titles were also available for download. The automatic synchronization between my Kindle and Audible accounts was seamless and the audio books sound great on the Kindle. I was able to pick up reading Stieg Larssons, ‘The Girl with the Dragon Tattoo’ where I had left off on my android device.

Free 3g wireless for the life of the service/device. What a deal!! No contracts, no fees just download content from anywhere with 3g data. It even works with Edge if 3g isn’t available.

The Bad

The price of e-books. You’ll notice I ‘purchased’ a lot of books at no cost, this sounds great, what can I complain about? The reason I selected free books is that current books are in my opinion over priced, as a rule of thumb, e-books are priced the same as paperbacks, or a smidgen less. Don’t blame Amazon, they wanted to price most e-books at $9.99 or less, but the publishers lead by Macmillan were successful in strong arming Amazon into charging more. Read more here . It is dismaying to see Apple at the center of the price hike as a result introducing the iPad earlier this year. More competition leads to higher prices!?! Am I missing something? I refer to higher e-Book prices that is, thanks to Apple the Kindle price is cut in half, hence my purchase :-)

Amazon advertise the latest Kindle as having 4GB of storage. Well actually its more like 3GB usable storage. I’m accustomed to GB inflation from hard drive manufacturers, but 25% difference? Hmmm….

The Ugly

‘Experimental Features’ such as the MP3 player and Web Browser are not easy to use on the Kindle. The MP3 player is simply a jukebox that plays your MP3′s in the order they were loaded on the device. No controls.

The Web Browser is slow and very difficult to use without a pointing device. Using up/down/right/left arrows to navigate is very frustrating. One good note however, the browser scores 100 on the acid3 browser test and renders sites such as Gmail very well. Why offer a browser at all? To sell books of course.

Summary

I like it. I like it a lot. I recommend you get one even if you already have a laptop/notebook/iPad. This dedicated reading device is very compelling.





Why Amazon’s Kindle vs iPad ‘pool ad’ is a mistake

17 09 2010

Recently Amazon have aired an ad that makes fun of the iPads readability (or lack thereof) in bright sunlight.

In my opinion this is a huge mistake. The two products are complementary not competitive. What Amazon should be doing is comparing their Kindle Library to the Apple iBook Library. Content is king, devices will come and go, ones e-book library will by contrast persist for much longer.

Amazon’s Kindle library can be accessed on a wide range of devices, including the iPad no less. Making fun of a platform that you officially support is rather silly. Do Amazon really want to sell Kindles or do they want to sell Kindle books? Kindles are merely a delivery mechanism for the real product, a book, magazine, newspaper etc.

There are so many great things about the Kindle ecosystem that they could promote, the device isn’t that important. The fact that the 3g model has free worldwide 3g without any monthly cost or commitments is quite frankly amazing, push this and compare to the price of the iPads data plan. Free vs $$$ per month.

The black art of Wireless Networking

16 05 2010

It rained all day today so I was able to resolve a wireless issue I had experienced on a laptop a friend gave me to repair/rebuild.

After replacing a faulty hard drive and loading Vista from scratch I discovered the wireless would not link in to my wireless network.  Other computers in my home ran just fine on the wireless network so I ‘knew’ there was no problem with my network. In addition I could boot the laptop to Ubuntu 10.4 on a  Live CD and it worked just fine too. This ruled out the laptop hardware as well. The finger pointed at Vista and the Intel Drivers.

After a reload of the Intel drivers from both HP and Intel, and a reload of Vista from scratch again and still no joy. I was running out of options.

I did discover that if I set the IP address as fixed on the laptop it worked just fine, so it was connecting to the router just fine but not getting an IP address. Puzzling since I could get an IP address assigned automatically using Ubuntu using the same wireless adapter.

Out of options I rebooted a wireless access point even though all other computers and the same computer using Ubuntu worked just fine. That fixed the problem. Note the router I rebooted was NOT the one assigning IP addresses, just the access point the laptop was connecting to. Somehow the access point was preventing a specific combination of hardware/software from getting an IP address from another router. Weird.

Not sure what can cause a specific combination of Wireless router, Operating systems and Wireless divers to fail to get an IP address, but there you go. Wireless sometimes eludes any logic.

The old axim of  ‘reboot and try again’ lives on….

Solid State Hard Drives – Performance Boost worth the money?

25 04 2010

Short answer – No.

Long answer follows.

I recently compared the performance of a good quality Solid State Hard drive compared to a traditional magnetic hard drive in use in most computers today.

My tests were restricted to start-up and shutdown times on a new Acer Netbook. Here is what I recorded.

Windows 7 Starter Edition – 32 Bit

Conventional Hard Drive – 160GB 5400 rpm Hitachi

  • Start-up time – 31 seconds
  • Shutdown Time – 11 Seconds

Solid State Hard Drive – 80GB Intel Mainstream

  • Start-up Time – 21 Seconds
  • Shutdown Time – 8 Seconds

This shows about a 1/3 reduction in time to start-up or shutdown the same computer with an identical installed image of Windows 7 Starter Edition. The solid state ‘mainstream’ hard drive from Intel costs around $200 and is only half the capacity of the original drive shipped with the Netbook. So it only makes sense if you really need to have every piece of extra speed or durability from your computer. (The Netbook only cost $225 to purchase in the first place). To buy a 160GB Intel Solid State drive to match the 160GB traditional drive would cost $400.

The start-up and shutdown times were averaged over three operations. Start-up was measured as the time it takes from the power button being pressed to a password prompt being presented. Shutdown was measured from the time shutdown was selected until the computer turned itself off.

By Comparison Ubuntu 9.10 Netbook Remix on the same Intel SSD took 14 Seconds to start-up and 5 Seconds to shutdown.

The drivers for investing in a Solid State Drive should be

  • The need for every bit of speed one can muster
  • The need for a drive that is very durable and can absorb shock and impact of up to 1500G’s without failing.

Use cases that come to mind are

  • Server System Drives, where speed and not capacity is most important.
  • Laptops that are subject to considerable vibration/impact. Either in an industrial environment, or subject to constant vibration in a moving vehicle.
