Troubleshooting Wireless Connectivity Issues with DW1501 Wireless N WLAN Half Mini Driver

I'm reaching out for help as I've been experiencing issues with my new Dell Inspiron laptop's wireless connectivity. Specifically, I'm using the DW1501 Wireless N WLAN Half Mini driver, but it seems to be having trouble connecting to my network from anywhere in the house.

To provide some background information, I've run the Windows Network Diagnostics software and generated reports that I'll share below. My HP work laptop has no issues connecting wirelessly to the network from any location in the house. However, when trying to connect my new Dell Inspiron laptop wirelessly, it simply won't work.

Interestingly, both my PC and Inspiron R laptop can establish a wired connection to the router and access the internet without issue. This problem started a few evenings ago, and I've tried troubleshooting but haven't been able to resolve the issue.

For some context, there's also a Dell Dimension 5150 PC connected to the same router. My Eircom 3 MB broadband package is functioning normally, and I'm using a Zyxel router. Initially, wireless internet connectivity worked fine from anywhere in the house for the first three or four weeks after setting up my new laptop.

I've tried various troubleshooting steps but have yet to find a solution. If anyone has experienced similar issues with the DW1501 Wireless N WLAN Half Mini driver, I'd greatly appreciate any advice on how to resolve this problem and get my Inspiron R laptop's wireless connectivity working smoothly again.
