Intel WiFi/WiMAX 5150: HOTKEY doesn't work without Access Connections

Our company has several T410i 2522-P38 notebooks with Intel 5150 WiFi/WiMAX cards, all still running XP. Recently I had to reinstall OS on one machine. There was a minor problem that Lenovo support site download page for this machine offers Intel WiMAX 6205 instead of 5150, but I have driver package stored.


This is not first time I face such problem, so I tried to solve it in usual way: uninstalled and reinstalled Hotkey package and drivers (Power Management driver and WiFi), tried several different versions of drivers and Hotkey - all to no success. Whatever I was doing, only BT was seen in Fn+F5.

FinallyI ended up reverse-engineering Hotkey, and got quite unexpected result: it simply doesn't know WiFi driver present on the notebook. Hotkey package (namely, TpFnF5.exe file which creates Fn+F5 window) has a hard-coded list of known adpater Hardware IDs. Intel WiFi Link 5150 present on the notebook has ID VEN_8086&DEV_423D&SUBSYS_13168086, while closest match in the list was VEN_8086&DEV_423D&SUBSYS_13118086. As an experiment, I've patched TpFnF5.exe to replace "13118086" with "13168086", and voila - WiFi appears in Fn+F5, and can be switched on and off!

Ok, thereason is found, but how all other identical machines work?! I checked another notebook, and found the difference: it had Access Connections installed, while the troubled machine had only Hotkey but not AC. It turns out that Access Connections has it's own executable for Fn+F5 dialog, AcFnF5.exe. When you press Fn+F5 with AC installed,

Lenovo Computer Won't Connect to the Internet After Sleep Mode

Windows 7 may fail to connect to the Internet after being in sleep mode for any number of reasons. The issue could be with the computer's hardware, the operating system or the router that connects your computer to the modem and the Internet. In most cases, the steps required to fix your computer will require an internet connection, although you can do some without. If you're using a wireless connection, make sure you try connecting with a cable as well. In many cases, a wired connection will work when a wireless connection won't.

Expand the Start Menu and type "Device Manager" in to the Start Search. Select "Network Adapters."

2.     ConfigureWLAN Settings

Click on the Start Menu and select "Run." Type in "services" and press enter. This opens the Services window.

At the bottom of the list, find "WLAN AutoConfig" and right click on it. Select "Properties."

Set the Startup type to "Automatic" and click "Start." Press "OK" and close the Services window.

3.     Configure Your Router

Navigate to your router's setup page if you have one. In most cases, you can access the setup page by typing the following into your web browser: "//192.168.0.1" and pressing "Enter."
