Thinkpads Forum

hello
I have a pc Lenovo T410, I tried several wifi cards, every time I get the message no Authorised card ... error 1802, after several searches, I found this:

I burned the CD and boot it, when I write "no-1802-nothing happens.
you have other options.
thank you

Use a WiFi card that has a Lenovo FRU number on it, specifically one of the models listed in HMM for T410. The best one that is a no hassle solution is the Intel 6300. The Intel 6200 isn't so bad either. They can be had for cheap on ebay. However, before you bid, verify that an FRU number is printed on the card, don't just take the seller's word for it. Demand a photo if it isn't already provided.

As far as options for the cards you already have, you have to get the hardware id numbers written into a custom BIOS with a BIOS editor software, then flash that to your T410. Some folks have no problems with that and are able to do it quickly. I'm not as bright, and it took me a couple of days to figure it all out.

For me, it isn't worth the hassle when the Lenovo cards are available so cheaply. For others, like this person, it is no big deal: http://forum.thinkpads.com/viewtopic.php?f=45&t=110160

Welcome to the forum!

The "no-1802" hack only works on T42 and older ThinkPads.

For T410, you need a modded BIOS, or a genuine Lenovo card with a FRU number.

Good luck.
