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.
