X1 Yoga 2nd Gen: Intel AC 8265 max speed 300 Mbps?

2017-07-29, 2:41 AM

Hi, 

 

Maybe this is a dumb question, but I couldn't find the answer... Lenovo X1 Yoga 2nd Gen's Intel AC 8265 should be able to work at 450 Mbps, but it only works at 300 Mbps. 

 

Does it have only two antennas on the OLED model so it can't reach full speed, so to speak? Or is it related to something else? 

 

Thanks!

Hi

What network band/mode does the wifi card work in? And what's the channei width (bandwidth) value?

Hi,

It works on both 2.4 and 5 Ghz. Channel width options are 20Mhz only and automatic. right now is set in automatic (if not, it goes down to 144Mbps).

The bandwidth 20 Mhz isn't enough to reach high data rate you need, disregading the network mode. For details read the manual. For example
https://en.wikipedia.org/wiki/IEEE_802.11

On the other hand, the more bandwidth value, the more overlapping of the neighboring networks.

Thanks for your reply. I understand that, didn't take a look at that before. But... Shouldn't this card be able to reach 450 Mbps? http://ark.intel.com/products/94150/Intel-Dual-Band-Wireless-AC-8265

I must be missing something...

As you see - yes, with some router/access point fixed settings and appropriate ones on the laptop adapter side (usually, auto settings). Firstly, on the access point side -
preferable network band and mode, the channel number (usually, it depends on the country), its bandwidth.
