I have just recently acquired a pristine X301 (2777-MSU) and I am completely in love with this model! I am interested in installing a WWAN card and what have found searching on the net is that there are 3 possibilities. I live in Jakarta, Indonesia and it seems that we are running on GSM 900 and 1800 plus UMTS 2100. Can anyone in this forum advice me on which card would be the most reliable one? I read somewhere that Gobi has a better reception than the Ericsson although it seems that this was hearsay.

I did read someone on this forum mentioning that they were successful in installing the Gobi 2000 but had to run a modified BIOS. Is this safe? CORRECTION: I found this page from Lenovo so I guess Gobi 2000 is available for the X301 http://support.lenovo.com/en_US/downloa ... MIGR-68493

Below are the options that I have found on ebay:

Ericsson F3507G FRU:43Y6537

Gobi1000/UNDP 42T0961

Thinkpad Gobi 2000 3G WWAN card 60Y3183

BTW, I am running Windows 7 64bit Home Premium.

Thanks before hand guys.

You can install Gobi 2000 with regular Bios as long as you are using the newest BIOS update.
Gobi 3000 needs an white list BIOS for non Lenovo cards.
Personally, I would get which ever card is cheapest in your region.
There are barely any difference between Gobi 1k and 2k.
Gobi 3k is hard to get working, and even then the upgrade is negligible since most Asian carrier still use some older technologies for wwan.

Thanks Kaze22. What you are saying makes a whole lot of sense.

I finally got my Gobi 2000 and I have run to the newest BIOS update but I am getting an error message "1804: Unauthorized WAN card is plug in..." Is there anything else that I can update or install to get the Gobi 2000 to work? Thanks

Just found out that the driver that I am supposed to download prior to installing the Mobile Broadband Connect software does not state X301:

http://support.lenovo.com/en_US/downloa ... 38#systems

Could this be the problem?

Don't bother just use Lenovo System Update to automatically search out the driver for you.
Unless you are running an non whitelist card, it'll find and install the right driver automatically.

I have run and updated through the Lenovo System Update but still getting the error. The Gobi 2000 seems to be on the list as a compatible card for the X301 unless I am mistaken.

It is, it should work.
If you still have problem. Have you updated to latest bios?

File names.
6jwa11ww.exe (Windows 7)

7twa71ww.exe (Windows Vista)

Look for those.

I have downloaded the same file 6jwa11ww.exe and it's still giving me the same 1804 error and I have updated to the latest BIOS from the Lenovo site as well. Any other ideas?

This is the latest BIOS v 3.15 that I ran for the 64 bit: http://support.lenovo.com/en_US/downloa ... D=DS003461

Can anyone confirm whether the GOBI 2000 is compatible with the X301? I am running out of options and have tried every possible updates on drivers and BIOS and I am getting no where.

Check your PM.

My interpretation of the first link you gave is that it applies to 3 cards - Ericsson F3507g, Qualcomm Gobi1000, Qualcomm Gobi2000. Not all of these will apply to the X301. As you have discovered the Gobi card does not work on the X301. I have modified the BIOS on my x301 so can say the procedure is safe. I modified the BIOS to use the Half Mini PCIE slot for a micro sd card reader and it worked.
I would assume that is your only option.

I already gave him a no white list bios, but didn't seem to fix the problem.
I have no idea whats going on. I'm stumped.
Maybe you should send him your modded bios and see if that helps.

Card may be bad.
