RB ac2 and RT5370 - 802.11n-only issue

RouterOS Wireless Networking

Hi,

I was searching for days about my issue, but I can’t solve it yet.
I have USB dongle with chipset - RT5370 (Railink) and it doesn’t connect to my Hap ac2 on 2.4ghz (802.11n).

Here’s what the log says:
2.4ghz: denying assoc to {MAC_ADDR_HIDDEN}, does not support all basic rates

Here’s my 2.4Ghz Wi-Fi config:
name=“2.4ghz” mtu=1500 l2mtu=1600 mac-address={MAC_ADDR_HIDDEN} arp=enabled interface-type=IPQ4019 mode=ap-bridge ssid=“{SSID_HIDDEN}” frequency=2427
band=2ghz-onlyn channel-width=20/40mhz-XX secondary-channel=“” scan-list=default wireless-protocol=802.11 vlan-mode=no-tag vlan-id=1 wds-mode=disabled
wds-default-bridge=none wds-ignore-ssid=no bridge-mode=enabled default-authentication=yes default-forwarding=yes default-ap-tx-limit=0
default-client-tx-limit=0 hide-ssid=no security-profile=default compression=no

I’ve tried to change default rates, but without success.

Any help will be appreciated.

P.S. This dongle connects at 54Mbit (when I switch to 802.11-g/n) and it doesn’t work on 802.11-b/g/n.

RT5370 specs claim that it’s fully 802.11 b/g/n compliant (and IPQ4019 does as well). But I guess it depends on driver used as well, it can change behaviour considerably.

We all know that hAP ac2 has its own share of problems with certain devices, but I wouldn’t dismiss the idea that it’s client machine requiring something supposed to be optional. Can you change some configuration parameters on your client machine?

Hi,

thanks for your reply.
The client is mag-324 (infomir) and I can’t change much (nothing) on client-side.
The thing is that this dongle works with TP-LINK 802.11n router without any issues, so my suggestion is that the problem might be in Hap AC2’s configuration (default config doesn’t work at all).

P.S. is there any more verbose logs than wireless, debug?
