Does anyone have wifi underperforming on Lenovo 7 Pro?
Hi! I've recently purchased a Lenovo Legion 7 Pro - 16IAX10H I've instantly noticed a decreased performance in download speed compared to upload speed. I'm on a fibre connection (950mbps/500mbps), going through an asus router RT-AC86U on the 5Ghz network. On normal internet speedtests I get 200 MBits/sec download rate and 500 MBit/sec upload rate. My other devices (Android, MacBook pro) have an average download rate of 700~ MBits/sec and upload rate of 500 MBit/sec. I usually do my tests at 2 Meters away from the router (direct line of sight).
I did update the bios (automatically detected by built-in software) and also updated the wireless card firmware going to intel dedicated support site. This did marginally improve the situation but still I'm getting lower values of downstream than upstream speeds.
Just wanted to have some opinions if this is something that is a known issue of this board and if it can be fixed through software or if it is a hardware issue and I should just contact Lenovo support.
I did a similar test (but not that comprehensive) using an ubuntu live boot and got similar results.
Instead of relying on speedtests I just went and started doing some local testing using iperf3.
Below I'll post some information about my router, wireless interface, and iperf results. (Iperf server running on an ethernet RPI4) Btw, I have done similar iperf tests on my android phone (against the RPI) and also a MacBook pro and got much higher results going through the same 5ghz wireless router.
This is the regular results I get from Iperf (Upload result first, download second)
