W520 and Intel 7260 802.11ac-card

2013-08-07, 23:10 PM

Anyone know if the standard Intel 7260 .11ac wlan-card can be used in the W520?

 

I upgraded my old T61p with a Intel 6300 a few years back. For that there was a hacked BIOS because only cards with Lenovo part number could be used. But from I remember it was also possible to upgrade to a 6300-card that had a Lenovo part number. So far, 7260-cards with Lenovo part numer ain't available...

If you have a hacked W520 BIOS, you can put it without a problem. If you have bluetooth module that is separate from the WiFi card, most likely Broadcom, it will cause a conflict with the integrated Bluetooth of the Wireless-AC 7260 making you end up with no bluetooth at all. Even disabling the Broadcom bluetooth won't work. You'll end up with both yellow marks on both bluetooth modules (Intel and Broadcom). However, if your W520 shipped with Intel Centrino Advanced-N 6235, you won't have any problems upgrading. That's why I have the Wireless-N version instead of the Wireless-AC version since the N version does not have integrated bluetooth and this makes my Broadcom bluetooth function without problems. I don't if the same case will happen on the W520 with separate bluetooth and WiFi card though.

I have a T510 with a de-whitelisted bios, no OE bluetooth and an Intel® Dual Band Wireless-AC 7260.

 

I've posted about my experiences here along with a lot of others in the rest of the thread.

 

In a sentence, the wifi works and the bluetooth seems to work using Win 7 generic drivers; it will take some playing around with the driver configurations.

 

cbautis2: What do you think would happen if you disabled the OE bluetooth daughter card in the BIOS? It could hiccup, but if the OS can't see it then maybe the 7260 AC and its bluetooth could work.

 

It should not be difficult to take out the OE bluetooth daughter card from a W520 (removing the keyboard & top bezel exposes the card).

My BIOS was de-whitelisted too but not unlocked so there are no changes from the original BIOS aside from the whitelist. Unfortunately, the BIOS in Ideapad series is very limited where there is no option to disable Bluetooth. You can only disable WiFi and change boot priority or enable VT-x. Besides, the Lenovo Power Management also gets corrupted then my Fn buttons won't work since when I press Fn+F5 to summon the WiFi and Bluetooth on and off button, the picture below does not show up :(.

I realized it shortly after doing everything I could think of to make the Bluetooth working. I guess the Lenovo energy management software for Y470 does not function correctly if Bluetooth isn't working. If I uninstall power management, the some of the Fn buttons won't also work (eg. brightness Fn+up) and bluetooth still shows as yellow warning even if disabled. I'm happy with just getting a dual band capability for my Y470, and I would be really happy if Intel released Wireless-AC 7260 without the integrated bluetooth just like they did with the Wireless-N version. No regrets with sticking with the N as I found the 5 GHz Wireless-N more than enough for 1080p 18 Mbit/s AVCHD streaming on my USB flash drive attached to the router without buffering :). I wasn't able to achieve this stability with the Centrino 1000 due to the crowded 2.4 GHz band where the video sometimes stutters. It's also more than enough for 1080p MKV streaming so I'm happy with the upgrade nonetheless.

Not getting Bluetooth ain't a bit deal. I'm normaly not able to connect my Bluetooth-headset from Creative and Plantronics to this pc anyway after installing Windows 8  :-\ 

 

But getting better wireless performance is a huge "want"  ;)

 

Is there any BIOS-es available for download anywhere? I installed the latest BIOS through system update not long ago - not sure if BIOS kan be downgraded? Would have been good with a rather new BIOS with possibilities for a new wireless card.

802.11ac should be ratified soon and the wifi alliance has announced a certification program for the draft standard. As the technology settles in, more (stable) cards should become available.

well, with Intel having cards ready and the experience so far with the 7260 in a Dell XPS with Haswell, I would guess the card itself is stable enough.

 

For .11n we had cards for many years before the standard came our of draft...

I would love to stick this card in my W530, but last time I check the 430/530 series and possibly the 420/520s had SecureCore Tiano, which prevented whitelist removal, or made it really difficult.
