Slow WiFi access to LAN

ForeverNoob · 16 Mar 2020

Hello,

My PC (Win10/64 Home edition, fully updated) WiFi connection to the router is very slow. With wired connection data transfer speed is ~100MB/s, but over WiFi it drops to ~5MB/s. For comparison, my phone reaches 30MB/s on similar conditions. The computer is only 1m away from the router, so this is not a signal strength problem. The wirless adapter is a USB RTL8188EU with latest drivers. Network reset didn't change anything.

Any idea on how to solve this?

TIA

Looks like 802.11n is enabled.

Thanks.

Buy a quality up to date new dual band ac standard USB wireless dongle.

That one is a cheap single band N and a very old chipset, small inefficient antenna.

My router supports 5G wifi. I ordered a new dual band 1200mbps adapter, hope this one will perform better. Thank you all for your help.
