I am unable to establish a wireless connection via thinkpad.

If you get a 'Limited connectivity" on you wirelessconnection on your laptop, it means that the wireless card on your laptopprobably did not get an IP address from the wireless router.
To fix this problem, right click on the wireless icon on the Task bar and thenclick Repair.
This will force the wireless router to issue a IP address to the wireless cardon the laptop.

The MAC network card needs configuring with the router's security settings ie. SSID and encryption code etc, otherwise it cannot connect to the router wirelessly.

Hi
Please scan your system with proper anti-virus & don't use trendnet wireless software always use windows setting

Is the printer connected via wireless? When I recently connected up a new wireless printer to my UVerse network, the printer manual said that establishing the first connection works better via an Ethernet cable directly to the Uverse router. After the printer is set up once, then I could remove the ethernet cable and connect to the printer via wireless from all my computers.
For all wireless PCs that were previously connected via wireless to dsl, you need to create a new network connection for each one, then enter the key that is listed on the side of your Uverse router when prompted. Sometimes it takes a few minutes to establish the connection.
I am amazed that ATT was so unhelpful on these issues. I was one of their first Uverse customers in Texas, and several times over the last years, techs would visit my house to solve a problem or hook something up, explaining to me as he went. That their helpful attitude is deteriorating is a real shame.

Use FN + F5 to start Think pad Wlan Manager
Use it to manager your Wlan settings

Ok when looking at your question i became very currious as to the answer myself so i did a litttle research and i think maybe the info on this page here: http://www.eggheadcafe.com/software/aspnet/33307589/certificate-required-to-c.aspx
could be of some use to you . even though the link describes a diferent network adapter the information there is about the same exact error on a router of the same type

I hope this information helps ... if it does not then let me know and i will find some more answers since i used to have the exact same laptop that you have now R40

FN + F5 is normally starting your radio connection on Lenovo Think pad

You could try to manually set your IP address in the TCP/IP, the gateway and your ISP DNS

Hi,

To my knowledge, your laptop (IBM ThinkPad X30 2672) does not have any built-in WiFi. It's modes of connection are IrDA, modem, Ethernet, USP, Firewire aside from the regular serial & parallel. This would indicate that if you are wireless you either have a USB dongle or PCMCIA card. Please post back with your WiFi brand/model and your Operating System. Further, please post back likewise your WiFi AP/Router brand/model.

The message "a network cable is unplugged" pertains to the absence of a lan cable connected to your Ethernet port.

Good luck, kind regards and will await your second post.
