It may be how the wireless networks are configured (not the ThinkPad). For example, one of my clients has a wireless network that's configured for "G" only, so "B" clients aren't able to connect. Other possible issues include MAC filtering and key mismatch.
If you have not already done it, then wait. First, we have not approached this right.
Not enough info listed, and then you say, "I tried everything" or "I checked all the settings" but who knows everything you tried or checked.
So, since the problem's being stubborn, let's start over and do it right.
Info to list here:
1) Exact router model/ Laptop model, OS
2) show IPconfig stats for working connection on your Topcom and for the laptop when it's not working. This is important.
Assuming Win XP: start>run>cmd>ipconfig/all>right-click "select all">Ctrl-C> go to this reply window>Ctrl-V> edit out personal info
Repeat this for both connections as requested and post.
Actions: What John said: " start over with a hard reset of the wireless access point to factory defaults, keeping all security off until it's working.. "
I'll add that you want to note your router settings for the ISP and, if possible, save the settings to a backup file from within the router management screens. Are you familiar with all this?
Later you might look for "Thinkvantage Software Installer" on your laptop and get Access Connections installed. It may not be the problem, so wait a bit...
You're absolutely right. I haven't actually posted all of the settings I've tried changing. I'm busy for the next couple of days, but if you have the patience, I'll post them later.
