Z580 wireless card replacement

2013-09-05, 23:17 PM

Hello all!

I had been having some connectivity issues with my network at home and at school, and I had been experiencing some slow data transfer rates between my Z580 and my intranet in my home. I did some research and discovered that the Centrino Wireless-N220 wifi card in my laptop only supported 2.4Ghz wifi signal!

I started researching some other similar wifi cards to see if I could replace it. I did not find any other threads similar to my issue, and the intel and lenovo websites did not have a compatability chart. This being said, could I just swap out the crappy Wireless-N220 with something like an Intel Ultimate N-6300 or an Advanced N-6205? The cards both use the same PCIe slot, and are just about the same size.

The ultimate question: can I just swap cards and be on my way?

The short answer is no.  The longer answer is yes - maybe - but not with one of those cards.  And probably not in the 5GHz band.

 

Lenovo laptops typically use a BIOS whitelist for wifi cards.  In order to boot with a wifi card installed it has to be a whitelisted model (Intel 6150NX, for instance) and have a Lenovo FRU number (20002484 for that Intel card).  A plain-vanilla 6150NX won't work.

 

The hardware maintenance manual contains the list of supported cards and their FRU numbers:

After a quick look through the list, it doesn't appear that any of the supported cards support 5HGz :(  I'm just basing that on the lack of "A" in the features list (BGN vs AGN) that usually indicates 5GHz capability.

 

I'd be happy to be corrected on this one.

From your hardware maintenance manual, these are the only supported Wi-Fi cards that are on the whitelist:

13 WLAN, WiFi 1x2 BGN + WiMAX, Intel 6150NX MOW M
PCIE NB HMC (LI) (Z380/Z480/Z580)
FRU no. 20002484
13 WLAN, WiFi 1x2 BGN + WiMAX, Intel 6150NX BSB M PCIE
NB HMC (LI) (Z380/Z480/Z580)
FRU no. 20002543
13 WLAN, WiFi 2x2 BGN, WLAN, WiFi 2x2 BGN, Intel 2200N
MOW M PCIE NB HMC (Z380/Z480/Z580)
FRU no. 20200048
13 WLAN, WiFi 1x1 BGN, Cbt BCM4313 MOW M PCIE NB
HMC
FRU no. 20002505
13 WLAN, WiFi 1x1 BGN, Liteon AR9285 HB95 BGN MOW NB 
FRU no.20002357 F0200045 13 WLAN, WiFi 1x1 BGN+BT4.0, Cbt BCM4313HMGB BGN+BT HMC FRU no. 20002501 13 WLAN, WiFi 1x1 BGN+BT3.0, Liteon WB195 BGN+BT HMC
FRU no. 20002524

 Sadly, there are no 5 GHz compatible Wi-Fi card on the list. However, you can still try the Lenovo version of Intel Centrino Advanced-N 6235 FRU P/N 04W3777 and see if it works. I haven't seen a person try this on a non-Thinkpad laptop so I'm wondering if it would actually work.

Well that's nice of Lenovo. Only make outdated WiFi cards accepted. I could try the Thinkpad card and see what happens, or I wonder if you could flash the BIOS and install a new one (say designed for overclocking) that would not have the whitelist. I built a desktop with an ASUS motherboard, flashed the BIOS, installed a new one, and was able to work wonders with it.

You can flash a unlocked BIOS that has more bells and whistles plus without the whitelist for sure, but if the BIOS bricked your laptop, you won't get any warranty for it. Flashing a hacked BIOS will void warranty. BTW, Intel 6235 and Intel 2200 aren't outdated. They are still being sold to the current Thinkpad lineups.

Pardon me, I just don't understnad why they would put a lock for these wirelss cards on there in the first place. The 2200 isn't awful, it's just a system bottleneck for me. I'll do some research into the inner workings of the BIOS and see if I can create my own solution or find someone who has before. I will update the thread with what I find.
