Unauthorized network card

Just got a new IBM a/b/g wireless LAN card. installed it fine, but now i'm getting an error:
"ERROR 1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card."
I've read some things online, and supposedly there is supposed to be a DOS program you can run to disable the wireless check:

unfortunately the file isn't there anymore! any idea what to do now? anyone have the file to get rid of the check?
thanks!

If it is a genuine IBM card you should not get that error, what model system are you trying to use it on and what bios version are you using.

I would suggest update to the latest bios and it should be fine

i'm using a T40 2373-516, and the card was bought from IBM and is listed as "IBM 11 A/B/G WIRELESS LAN MINI" part 73P4301.
so flashing the bios should be ok?
any particular program to do that?

Try updating your BIOS. You've probably got the 2nd revision of the IBM card which came out after the T40 was released.

I have one question. Other than profit why does IBM restrict hte card? Does the IBM card have some kind of security or other feature hte other cards would tamper with?

Supposedly it's an FCC thing.

I used the no-1802.com file 3 weeks ago after purchasing a non-IBM Wireless LAN card (2200BG). Works like a charm

The file is there now. I had no problem re-downloading it.

The T40 requires the BIOS upgrade to work with the a/b/g card (it was manufatured before the a/b/g standard was available).

yeah the T40 Bios didnot have the A/B/G card id in it, since it was not available then,

I guess if you use any bios version higher than 3.06 you should be fine,

you can download the bios diskette from ibm downloads

Hi all, sorry to dig up such an old thread, but I have just received this error (#1802), and I wanted to ask your diagnosis:

Last night we left my parents' X31 on, and in the morning, the screen was in DOS mode with that error showing up. Restart did not help -- it would stop after the bios screen. Luckily, we are actually using a Netgear PCI wireless card instead of the builtin wireless (reception issues, and not behaving quite right all the time), and I disabled the internal wireless in the bios, and started up normally.

I have a feeling it downloaded some kind of Microsoft update overnight and restarted (I hate this), but why would that cause the machine-level wireless card problems? This is not a good thing for people who would completely lose connectivity, hijacking their machine like that.

The laptop now works as before, but is that the end of the story? Or is this symptomatic of future additional problems to be expected?

thanks!

I had the same thing happen.

I use Vista Home Premium on my T42, and the next day i started my T42 it gave the 1802 error.

Guess it has something to do with an Vista driver update or so

Well, i re-applied the 1802 fix, and now it is working flawlessly again

I'm on a T40 (2373-6u0) with factory Cisco "B" wireless card (MPI350 U58H004.3). Worked fine 'til this week, when I started getting the "1802" error. I'm on latest driver (no recent change), latest bios (ditto).

Odd thing, It does not happen when I start with a cold machine, only when I've run for a while and reboot.

Has anyone else out there experienced this? Is it an intermittent heat-related problem on the wireless card? The mobo? (BTW, this mobo had its ATI Radeon video card reflowed about a year ago by First Phase).

Thanks.

@isaacb:

Welcome to the forum!

A machine that decides to start throwing "1802 error" out of the blue likely has a motherboard problem, and not a heat-related one at that.

Good luck.
