Hap ac2 DHCP Client not working on 2G WLAN station

I had previously (couple of month back) already some issues with hap ac2 as “repeater” while on the road:

  • 2.4G WLAN as station connected to remote GW, WLAN 5G as my local Wifi router for my laptop and phone etc.

Now last week I had the time and occasion to again try to this up in a different place and had again issues:
Only changes made are (on 6.45.6):

  • Reset hap AC2 with default config (dual band AP)
  • remove WLAN1 from LAN list, and as well from BRIDGE
  • add WLAN1 to WAN i/f list
  • add DHCP client on WLAN1 i/f
  • Set WLAN1 to station mode, add SSID and security profile as needed
    → Wifi connects ! Great!
    → DHCP client does not get any IP address, status “searching”. Log shows that requests where sent

Other devices do connect to the AP (in this case was a Tenda hotel AP).

Any idea? I saw this DHCP client issue before but never had time to check it out.
It is really annoying as I like such setup (2G Station with 5G Wifi) but it does not work in many places due to this issue.
Did I oversaw the obvious ?

DHCP works in Layer2, however Station mode does not…

Assign static IP to wlan1…

Edit:
I did a test and DHCP client works fine on station mode…

Works fine here. Same device.

Hi Zacharias, Znevna,

thanks for your response. Gives me hope .

Do you connect hap ac2 as a client to a Mikrotik AP or some 3rd party AP?

Could it be that “station” implementation on Hap AC2 has issues?
When doing torch on wlan1 I see that no (zero traffic/packets) came back from the AP to the client (DHCP request goes out, but no RX frame received).
This while wlan1 interface shows “connected” …

No

In the test above I was connected to an Asus AC58U.
I’ll cleanup my config and post it here so that you can compare it with yours.

Hi Znevna,

Thanks for sharing this.
It’s exactly my config I used.

I will monitor and try to do some tests in the coming weeks.
