Slow Wifi Speeds On RB4011iGS+5HacQ2HnD

Sun Feb 06, 2022 1:13 am

I have been using the Mikrotik routers since 2017 my first being a RB750Gr3 and now I have a RB4011iGS+5HacQ2HnD. I have an ISP 1 Gbps Fiber to the Home internet connection which is shared however when I am hard wired to the router I get 500 Mbps Up and 700 Mbps download which is understood and acceptable. On the flip side when I am connected wirelessly to the Wifi Router I get very poor speeds of 120 Mbps and lower. See setup of router below. Any help in identifying a likely misconfiguration or how to get speeds of 500 Mbps using Wifi would be greatly appreciated.

RouterOS.

Pick another vendor for wireless.

Cambium XV2-2 WiFi6 WAP connected to my hAP AC2.

MT 5GHz UDP data throughput is 260Mbps for 40MHz/2S/SGI and only 360Mbps for 80MHz/2S/SGI.
TCP may be slower due to TCP congestion avoidance, and some wifi glitches in the 6.48+ ROS versions.
500 Mbps only with ROS7 and wifiwave2 drivers

Hint: avoid WPA and certainly TKIP in wifi security.

Unfortunately I live in a HOA so I have no option of choosing another ISP. After tweaking the frequency setting for the 5 GHz I was able to get 150 on the Wireless when connected on the wireless and when hard wired to the router I get 400 Mbps. I post my configuration for that change shortly.

Put your wireless access point of choice ontop of the RB4011, and turn off the Mikrotik wireless.

Any suggestions ?
