Extremely slow WiFi - Legion 7 15IMH05

2021-01-13, 2:46 AM

https://www.speedtest.net/result/10739358949

 

I only getting around 10 Mbps on this computer, though it is jumping from about 6 to 12 every half a second or so. My phone is getting a 256.24 average on the same network. I can't seem to figure out what is up. I've tried resetting my network, the WiFi card, and even uninstalled and reinstalled the drivers. I was getting much higher speeds on this computer previously but have struggled to get anywhere near a decent speed out of it the last couple of days. 

Solved! See the solution

That model comes with the Intel AX201NGW wireless card that supports the Wi-Fi 6 802.11ax protocol, which on may older routers provides poor performance, especially in areas where there are other WiFi 6 802.11ax devices within range.

 

I would suggest you do the following to test and see if it will provide the speed you expect in 802.11ac mode vs 802.11ax

  • Right-click Start and select Device Manager
  • In Device Manager, left-click on Network Adapters to expand that section
  • Right-Click on your Intel AX201NGW wireless and select Properties
  • On the Properties page, select the Advanced Tab
  • Scroll down until you see 802.11n/ac/ax Wireless Mode or HT Mode and expand that section
  • Select VHT mode or 802.11ac and select OK to save.

You might have to disconnect from your WiFi hotspot and reconnect, but it should change automatically.

 

If your other devices are getting 256.24Mbps on a 5Ghz connection via 802.11ac. your laptop should be able to do the same. 

 

 

Regards,

Thanks for the info, but I think I managed to get it solved on my own. I had turned on the Network Boost option in the Vantage software and I think it got stuck. As soon as I disabled that option, my speeds went back to normal.
