Fix – Dell E1505 Intel Wireless Card Drops

Recently my girlfriends laptop has been unable to reach the internet via wireless.  The symptoms are pretty eratic and hard to tie down.  Initially web sites will load but after a couple minutes all network activity will drop.  The interesting piece is that the wireless signal and all monitoring details show as good.

Symptom: All wireless network packets are dropped 1 minute after connecting to wireless access point
Wifi Card: Intel Wireless Card 3945ABG
Laptop Model: Dell Inspiron E1505
Driver Version: 11.5.0.32 (9/26/2007, Intel)

Fix: Within the network adapters properties force the wireless card to only use 802.11G.

Update Wifi Properties

  1. Right click my computer and select Manage
  2. Select Device Manager and expand the Network section
  3. Right click the Intel(R) PRO/Wireless… adapter and select Properties
  4. On the Advanced tab scroll through the list of configuration options and select Wireless Mode
  5. Uncheck “use default value” and then select your wireless type ie. 802.11G etc.
  6. Click Ok and exit the computer management interface.

Windows – Password Recovery/Reset

This is absolutely one of the best free tools to reset the administrator password and gain access . It modifies the encrypted password in the registry’s SAM file allowing you access to the account in Windows NT/2000/XP/2003/Vista systems. There is an image file to create a bootable floppy disk or bootable CD to modify the admin password and access NTFS partitions. You do not need to know the old password to set a new one. It will also offer to unlock disabled or locked user accounts (a very helpful feature). The program was just updated on April 9, 2007 to include Vista support.
Visit the site by clicking on the link below to download a CD image or floppy image of this program.

Expansion of non-dynamic NTFS partitions can be accomplished by using the Microsoft Utility called DiskPart.exe.  DiskPart allows examination of disks, volumes, and partitions. Cloning of disk and also expansion on existing partitions.
