Hi bgktsl,

Welcome to the Community Forums.

Do you have a specific part number (ex. 01AX768 - Wireless,CMB,IN,9560 NV M2) for the Lenovo Wireless 2x2 ac?

Speed of WLAN card are designated through its 802.11 Standard so Intel Wireless-AC 9462 1x1AC and Lenovo Wireless 2x2AC both share generally same expected 5 GHz speed.

Similar to this post, difference between the two is the Multiple Radio Chains (2x2AC) offering number of transmit and receive radio chains. As example, the speed of the cars may be the same but 2x2 offers 2 roads so if there would be any network traffic on one road then the other resolves lagging as it provide alternate path.

I hope this helps answer your query or anything else that interest you.

I didn't know that because it only shows between 2 options like picture attached.

So, maybe someone who use Lenovo Wireless 2x2AC option can share the performance of it.

Becuase i found that Intel Wireless-AC 9462 1x1AC has max speed at 433 Mbps and 2x2 seems to have higher bandwidth.

Hi bgktsl,

Greetings.

81SXCTO1WWTH is CTO or custom to order (from major resellers) so parts may not be as specific if ordered from Lenovo. Using model 81SX for legion y540 15irh shows available WLAN cards as shown from parts lookup:

PN 01AX709
NFA435A QCA9377 (1×1)
Peak Speed: 433 Mbps BT ver 5

PN 01AX768
Intel® Wireless-AC 9560 (2x2)
Max speed 1.73Gbps BT ver 5

PN 01AX795
Intel® Wireless-AC 9462 (1×1)
Max speed 433 Mbps BT ver 5

PN 01AX710
RTL8821CE (1x1)
Max speed 433 MBPS speed BT 4.2

This appears that PN 01AX768 Intel® Wireless-AC 9560 is the only one that has 2x2 TX/RX Streams with bluetooth version 5 and  Max speed 1.73Gbps BT ver 5.
