|I'm using DSL. I should have said so. It just didn't dawn on me that anyone used dial-up any longer. My bad.|
As I said above, "I updated drivers for Network Adapters ( "Packet Scheduler Miniport #2" and "WAN Miniport (IP) - Packet Scheduler Miniport) to drivers from DELL's Drivers and Utilities CD which came with the Inspiron 4000 laptop" including wireless drivers for the wireless interface. I neglected to expressly state that I also installed the wireless drivers from the Dell "Drivers an Utilities" CD which came with the Inspiron 4000 laptop. I should have been more clear about that.
As soon as I can get access to the web, I will update to later service packs and update drivers for the wired and wireless adapters and modem.
I know it is an old laptop. I don't have much use for a laptop and just want to keep it functional for the few times I need use of a wireless connection.
If it makes a difference, my network is "hub and spoke" on a 3 Com 16 port switch and my router is an ActionTec GT784WN.
Please let me know if any further info will be helpful.
