My internet download speed from my D-Link wifi router is 24 M bits/s
From ethernet the download speed is 50 Mbits/s
I am using Tp-link AC600 Archer T2U Plus wifi adapter with Rapberry pi 3B+
I tried to use it with 5 Ghz and 2.4 Ghz both. The speed for the adapter is supposed to be 200 Mbps 2.4 Ghz / 433 Mbps on 5 Ghz.
But even with the 5Ghz I can get only 19 Mbps download speed when connected to the hotspot. It shows a network speed of 54 Mbps in my wifi settings whereas the D-link router shows 72 Mbps on the 2.4 Ghz.
Here is my hostapd.conf:
interface=wlan1 driver=nl80211 hw_mode=a channel=48 ieee80211n=1 ieee80211ac=1 wmm_enabled=0 macaddr_acl=0 ignore_broadcast_ssid=0 auth_algs=1 wpa=2 wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP ssid=Wlan1 wpa_passphrase=1234567a
What am I doing wrong here?
