DWL-G122 Rev. A2 Wireless Adapter on Linux

-
Finding working drivers for D-Link DWL-G122 Rev. A2 USB Wireless Adapter to use in Linux Mint 14 (32-bit) based on Ubuntu 12.10.

The adapter is only compatible with WPA and WEP security modes; not compatible with WPA2.  PSK can be used.  This adapter could not connect to a router running in 802.11g/n mixed mode; but does associate with a router set in 802.11g mode.

On Mint/Ubuntu, attempts to use the native p54usb kernel module, and the necessary isl3887usb firmware placed in the correct /lib/firmware path resulted in dmesg log lines "authentication with AA:BB:CC:DD:EE:FF timed out" despite success registering drivers to the interface.  See firmware installation instructions at http://wiki.debian.org/prism54. There appears to be a newer version of the isl3887usb firmware available here, http://wireless.kernel.org/en/users/Drivers/p54, which I did not try

I had success using the old method I had running on an earlier edition of Ubuntu. Ie. load ndiswrapper

Use ndiswrapper kernel module and install Windows drivers from D-Link website.  However, D-Link Support website does not list Rev. A2 (as of 2013-01) but the correct driver is available on their FTP server at: ftp://ftp.dlink.com/Wireless/dwlg122_revA2/Drivers/dwlg122revA2_driver_102.zip

Encountered "FATAL: Module ndiswrapper not found." when trying to sudo modprobe ndiswrapper or when trying to install Windows drivers for the adapter via ndisgtk.  Downloading and installing ndiswrapper-dkms_1.58~rc1-0ubuntu1_all.deb worked. Older version ndiswrapper-dkms_1.57-1ubuntu1_all.deb did not.  Follow procedures at http://askubuntu.com/questions/132894/how-to-fix-ndiswrapper-not-found

Probably want to blacklist p54usb if you want to get ndiswrapper to work.

Calculating total interest accrued while paying down the simple interest loan periodically.

-
I was unable to find a web service or calculator on any websites that had a simple interest calculator in which the total of the loan was being payed down regularly. I was forced to make one in Excel. There are plenty of amortization calculators out there that generate the schedule for a loan with compound interest, like a mortgage, but none that show the schedule for a simple interest loan, like some HELOCs (in Canada). My Excel spreadsheet allows one to compare an amortization schedule on a compound interest loan to a schedule for a simple interest loan. This is useful if you want to see the affect of making payments on a simple interest loan, equal to the same amount at the same time of the month on the same frequency as you would on a mortgage. The spreadsheet assumes interest for the simple interest loan is calculated daily and that payments against the loan are applied to the interest accrued first, and then toward the principal. It can be tweaked if you wanted to calculate i...

A list of "All-Weather" tires with the Mountain/Snowflake symbol and where to get them

-
Image
Though the design and compounds have been around a few years now, it was surprisingly difficult to find tires that are truly All-Weather (good for every season) per Transport Canada standards and meet or exceed the Rubber Association of Canada performance requirements. Since my tires need replacing and I'm not looking for soft winter-specific tires, I have compiled a list of tyres that have the mountain/snowflake rating based upon my search. Perhaps you'll find this list useful and that it saves you time. Nokian pioneered this class of tires and was the first to market but there are now a number of brands with a limited selection. http://www.wheels.ca/news/all-weather-tires-are-not-the-same-as-all-season-and-heres-why/ These makes include: Kumho, Toyo, Falken, Michelin, Vredestein, Hankook, Yokohama, and Nankang, Michelin, Multi-Mile, and Muteki.  Additionally, some are exclusively sold at certain retailers. Tires that have the 3PMSF icon and are all-weather cap...

New annoyances: Windows 7 and Bluetooth enabled devices.

-
Thorough testing on my part has proven that Windows 7 can not receive large files, approximately anything larger than 225 KB, from some Bluetooth devices. In this case, my Nokia 6301 can not send to the "fsquirt.exe" utility on Windows 7. I tested this with 3 different machines running Windows 7 (6.01.7600), two laptops with built-in bluetooth and a desktop using a bluetooth dongle. The error message offers no clue as to why or what happened. All it says is " Bluetooth file transfer not completed " " The transfer was cancelled by the Bluetooth device or Bluetooth enabled computer. " However, the Nokia 6301 has no problem receiving large multi-megabyte files from a PC running Windows 7. The Nokia 6301 is also able to send/receive large files to other devices (phones, PDA's), and computers running Windows XP, Vista, or Mac OS X. On the other hand, Windows 7 was able to receive files over bluetooth from other bluetooth-enabled devices, including: com...
