Hi everyone!
I am working with a multimode configuration using MikroTik NetMetal 5 devices and I need some help in understanding why I am getting incredibly poor performances. My devices are configured as follows:
Node 0 – Gateway: the first device works as a gateway. It gets connectivity through ethernet connection and its wlan1 is configured as:
Mode: ap bridge
Band: 5GHz-A/N/AC
Channel width: 20/40MHz Ce
Frequency: 5500
SSID: network_0
Node 1: this node uses two modules, namely wlan1 and wlan3 to get wireless connectivity from Node 0 and propagate it using a different band (eventually avoiding overlapping). The two modules are designed as follows:
wlan1
Mode: wds station
Band: 5GHz-A/N/AC
Channel width: 20/40 MHz Ce
Frequency: 5500
SSID: network_0
wlan3
Mode: ap bridge
Band 5GHz-A/N/AC
Channel width: 20/40MHz Ce
Frequency: 5240
SSID: network_1
Iperf tests between devices connected to wlan3 and devices connected to Node 0 showed good results (40-50Mbps).
Node 2: this nodes does the same as Node 1, using wlan1 to get wireless connectivity from it and using wlan3 to propagate an access point. Its setting are as follows:
wlan1
Mode: wds station
Band: 5GHz-A/N/AC
Channel width: 20/40 MHz Ce
Frequency: 5240
SSID: network_1
wlan3
Mode: ap bridge
Band: 5GHz-A/N/AC
Channel width: 20/40 MHz Ce
Frequency: 5500
SSID: network_2
Iperf tests between devices connected to Node 2 and devices connected to Node 0 showed incredibly poor results (1-2 Mbps).
I tried to tamper with settings, changing channel width, frequency and band but with no significant changes.
I also tried to work with a single module and virtual Aps, eventual turning off wlan3 on Node 1 and Node 2 and there have been some improvements (bandwidth raised to 10 Mbps) even if very unstable.
I have no clue about what needs to be modified in my setup to improve performances eventually allowing me to see at least 20Mbps on clients connected to Node 2.
Any suggestion would be very much appreciated!
