Slow Connections with Broadcom Wireless 802.11ac Chips
we are using several TP-LINK Archer T6E AC1300 Dual Band PCIe Cards with a Broadcom Wireless 802.11ac chip.They should have a maximum throughput of 867MBit/s-5GHz, 400MBit/s-2,4GHz, 802.11ac/a/b/g/n
Windows 10 64-Bit only shows a connection type of 802.11n and the maximum connection speed in most times is only 78Mbit/s only sometimes 130Mbit/s.
We tried different drivers and settings on the card, but its always the same.
Client connected to a R500 AP (RAP Mode)
AP Firmware 220.127.116.11.753
SNR 24 db
Radio Type b/g/n
Hidden SSID (OPEN / AES)
Fast Roaming enabled
Maybe someone has a hint for us why the client is not connection in ac-mode with faster speed?
