Will a 802.11ac USB adapter work on IdeaPad U530?

2014-02-10, 17:19 PM

I recently purchased an IdeaPad U530.  Around the same time, I purchased a NetGear Nighthawk AC 1900 Dual Ban (R7000) router.  All of my other devices connect no problem to the 5ghz wifi network from the router.  I realized the 5ghz band didn't show up on my U530, but the 2.4 ghz network appears.  

 

I did some investigation and found my new Lenovo laptop has a 7260 b/g/n card.  I thought, "That will be a simple fix, I will just replace it with an AC card."  Then I read:

   and

https://forums.lenovo.com/t5/General-Discussion/WWAN-and-wireless-card-BIOS-whitelists-Lenovo-COME-ON/td-p/952681

 

That was when I "unhappily" learned about Lenovo's "whitelists" for the first time.  I'm shocked that in 2014 I simply can't replace the wifi card in a laptop.  Had I learned about this sooner, the Lenovo would have gone back to BestBuy on principle.

 

I'm a basic user and I don't have the technical skill or time to deal with flashing BIOS, etc. . . so I have three questions.

 

1.  Will the Lenovo U530 allow me to use one of the 802.11ac USB adapters?

 

2.  Any recommendations on which USB adapter to use?

 

3.  Do I have to deactivate the Intel 7260 card before using the USB adapter?  If so, how do I do that?

 

Thanks!

Solved! See the solution

1.  Will the Lenovo U530 allow me to use one of the 802.11ac USB adapters?

IMHO why not? I use a usb dual wifi adapter myself although it's only a,b,g,n. It is more efficient than the built-in card.

 

2.  Any recommendations on which USB adapter to use?

Try going to Netgear's site and look for an AC dual band usb adapter to match your Netgear AC router.

 

3.  Do I have to deactivate the Intel 7260 card before using the USB adapter?  If so, how do I do that?

To avoid getting the system confused and make the setup of the usb adapter easier I think you can disable wifi in the bios. You will still have bluetooth functioning.

Thanks LenBlazer, I appreciate the help.  I found a Netgear adapter on Amazon and already ordred it.  It should be up and running by Thursday.

Hi there. Would you mind updating me with which USB WiFi adapter you settled on? I am in the exact situation with the same model laptop, and I'd love some suggestions on what to purchase.

I have the same issue.  I bought an Asus USB N53 adapter, and with the adapter in, I can access the 2.5 GHz portion of our router, but my top speed is 144 mbps.  Does your solution allow you to access the 5 GHz part of the router?  My U530 computer does not see that network at all.

Without the adapter, my speed ranges from 60-80 mbps, very disappointing.  When I called in to Lenovo, the suggestion was to get the adapter.  I asked if I can just trade in my machine, since it is the slowest thing in the house now.  :-(  Of course, that option is not available, and actually, I love this machine other than the slow speed.  Unfortunately, my job is all about VPN over the wireless.
