I recently bought a TP-Link WR841N v10.
In general it is working fine, but the WiFi speed never goes above 840kbps. With Ethernet it can reach speeds as high as 10-20 Mbps. However the WiFi seems to be capped at 840 kbps.
Is this expected? While I do understand that speeds can be slower at 2.4GHz, I still think that the speed is unnaturally low. I have WPA2-PSK authentication, channel width 20MHz at bgn mixed mode, and WMM activated.
