Hello everyone
-Manufacturer: Lenovo
-Model: Thinkpad T420i - 4177-x01
-Latest Bios Revision: 1.41
-Bios link: http://support.lenovo.com/en_US/download...D=DS018785


I m trying to get an wan adapter, but i m starting to learn there are a lot restrictions around this.

The lenovo models are way too expensive don't understand why what is the big difference with the other same chip models

official
60Y3279

it says this is the only board i can use 21Mbps

on eBay i find a lot boards really low cost that has the same chip but its not compatible with my lenovo or something Dodgy


http://www.ebay.com/itm/170904757665
http://www.ebay.com/itm/251146892345


it costs a fraction of any lenovo card Angry and it does the same thing.

How do i buy a compatible card or witch one i buy, but that doesn't cost 150 $

Is my laptop compatible with 60Y3255 board it dosent show on http://support.lenovo.com/en_US/product-...D=PD008442 ?

the gurus may know Smile



Thank you!

Many thanks for your reply. Can you tell me if having computrace is a problem? Will computrace prevent bios flashing? I semi bricked the machine but somehow I got it to boot and was able to reinstall original bios.

I installed this one form this post, any difference between the above and this?

Confirmed bios works fine, .bat file is not leading to the right path, but open it in notepad and you will know what exe to open.

It got rid of my 1802 error but now wont accept drivers. Any ideas? I tried everything for 6 hours.

F5521GW, if anyone knows why I cant install the drivers for this card please update me, after the bios mod I no longer get error 1802 but the machine will accept the drivers. Card is from june of 2011 and I feel that lenovos drivers online are not for the same version as I have, but windows says it found the correct driver but cant install it. Giving error ( code10). Kindly help.
