Hi SuperdooperRob, let’s try the following steps.
1. Completely uninstall Intel® PROSet Wireless Software from Programs and Features and install the newest version for the operating system you are using.
- Windows* 7: https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23723
- Windows* 8: https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23724
- Windows* 8.1: https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23726
2. Please make sure your wireless router is using the latest firmware. Intel® Wi-Fi Products — Access Point (AP) firmware updates may resolve wireless network issues
3. You may also want to verify that both the router and the laptop are using the correct security settings. Intel WiFi Products — Data rate will not exceed 54 Mbps when WEP or TKIP encryption is configured
If the issue persists please start a command prompt session (by pressing the Windows* key and the R key, then type CMD and press enter). We would like to get the wireless adapter’s IPv4 address and Default Gateway by typing ipconfig.
Then, while you are not far from the router, type: “ping <default-gateway-you-got-earlier> -n 100” so you can see how many packets get lost when this process completes.
Please share your results.
