T400 / How to remove 1802 Error

#1 Post by T400Ever » Fri Jul 27, 2018 12:44 pm

Hey all,
I get the 1802 error message by trying the Intel Wiereless AC 7260 card. Is there any BIOs patch for T400 to adjust the whitelist for WLAN cards?
Thanks in advance

Thanks a lot!!
I got a solution by the link recommended.
After some attempts and using the prior BIOS version 3.23 (7UET93WW) - not the latest Lenovo BIOS 3.24 - before patching it's working fine.
No error message 1802 and the router shows 560 MBit/s on the 5 GH band.
Great!
