Strange 2.4 ghz issue

I get internet from outside with Mikrotik to my flat. I distribute this internet as wifi with tp link. Mikrotik and Tplink dhcp off. devices taking ip directly from Zyxel modem. When i use on Tplink cable or 5 ghz i get full speed 100 mbps. But when i use 2.4 ghz i get 1 mbps or more less.
this problem started when i updated mikrotik 7.11 software. i downrage back any other versions still problem continue. İ tried 3 diffirent acess point all 2.4 ghz same problem very slow.

Incomplete information. It’s hard to answer. You show the 5GHz settings again.

/export file=anyname (delete router serial number, any public WAN IP information, etc.)

Couple of things to consider:

  • wireless-protocol=nv2-nstreme-802.11 means you will connect with either another Mikrotik or something else. Why not use 802.11?
  • authentication-types=wpa-psk,wpa2-psk group-ciphers=tkip,aes-ccm is beyond ancient. Change it to authentication-types=wpa2-psk group-ciphers=aes-ccm
  • **/ip dhcp-server

DHCP server can not run on slave interface!

add address-pool=dhcp interface=ether1 lease-time=10m name=dhcp1**
Change this to:
/ip dhcp-server

DHCP server can not run on slave interface!

add address-pool=dhcp interface=bridge1 lease-time=10m name=dhcp1

  • Are you really using directional on one site and omni directional on the other?
  • You are referring to 2.4GHz, while the RBLDF-5nD is 5GHz only, can you please elaborate?

Did I understand your description of the problem in the first post correctly?

the problem started to recur today. When i give manuel ip wireless devices. i have connection without problem. devices on wifi not get automatic ip. Directly on mikrotik eth cable i have always internet no problem. the problem when i put eth cable on tp link acess point devices sometimes get automatic ip sometimes cant get. i tried diffirent acess points. example when i check phone dhcp i see there phone get mikrotik dns. it should get zyxel dns . because on mikrotik dhcp already disabled. Devices must take all ip from zyxel. wireless devices try to take ip from mikrotik
