slow 5GHz speed on wireless-ac 3168

Hello,

My laptop has Intel i5 8250, 12gb ram, wireless-ac 3168.

 

My connection is 300/15 and i get the full connection over ethernet.

 

 

My router is dual band and i get around 50 Mbps on 2,4GHz and lower than 40 Mbps on 5GHz (even when i am 2m away from router).

 

I have the latest drivers.

 

 

I searched the web and tried a lot of different options and still i get very low 5GHz speed..

Hello lbuca, Thank you for posting on the Intel® Communities. Did you integrate the wireless card to your laptop? What is your computer model? When did the behavior start? Are you able to get better speeds with your router on other devices? Amy C Intel Customer Support Technician Under Contract to Intel Corporation

Model number: HP Pavilion - 15-ck005ng

upgraded my internet from 40Mbps to 300 Mbps few weeks ago and i got a new router from provider. Never had 5GHZ router before.

on my phone i get well over 200 Mbps, even when i am in another room.

 

was reading that you have to set HT to VHT to get ac mode, but i dont have that option in device manager.

Can you test another computer to check if you get better speeds with on the 5GHz? Please, try this driver: https://support.hp.com/us-en/drivers/selfservice/swdetails/hp-pavilion-15-ck000-laptop-pc/17296798/m... Amy C Intel Customer Support Technician Under Contract to Intel Corporation

I installed the drivers from the link:

Driver date: 12/03/2018

Driver version: 19.51.12.3

 

I still get under 40Mbps :(

tried and still the same result.

 

Driver date: 31.12.2018

Driver version: 19.51.18.1

 

So frustrating since my phone can get full speed with no problem and my NEW laptop with i5 8250 and 12gb ram gets max 40Mbps on a 300Mbps connection.

This does not seem to be adapter issue. It could be router or ISP. We need to know where are you reading the speed of the connection. Check with ISP the Access Point settings. I understand we have sent the advanced wireless settings but would be good to check with ISP. Did the you connect the computer with different Network environment?

Sorry i didnt see "load more answers".

 

i used speedtest on laptop and phone and phone had no issues going above 200MBps. Also when downloading games on xbox (wired connection) i get speeds of over 130Mbps. Even tried on an older phone and it got 90Mbps with a wall between the router.

 

I dont know anyone with a 5GHz router to check if it is the routers fault (would be weird, because my other devices work fine).

 

this are my settings:
