EAP 245 DHCP PROBLEMS
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hi Everyone,
I have router MIKROTIK which shares DHCP to the network. I installed 4 EAP 245 a month ago and everything was OK until yesterday. Now, it works on WIFI only if I assign static IP to devices. I can not find a problem. On the old WRT54GL, the device immediately gets IP. I can not find any settings to help solve this problem with EAP 245. Hard reset?

Hi,
You mean that when the EAP are assigned dynamic IP, the client devices can find the SSID but they can't connect to it, and when you assign static IP to EAP, the client devices can connect to the SSID, yes? Did the EAP get an IP address when you set dynamic IP? And did you set other settings for the EAP or for other devices in the network yesterday? I think you can update the firmware and reboot the EAP to have a try.

Sounds like a DHCP problem of the Mikrotik to me. Check the lease time - is it > 24h? If so, maybe the DHCP pool is exhausted?
The WRT54 in standard config is a router, the EAPs are APs. If not explicitly configured as an AP, the WRT54 uses its own DHCP pool for IP addresses of its clients and it would keep its own IP even if the DHCP pool on the Mikrotik becomes exhausted (as will the EAPs). Only clients can't get anymore IPs then and this could lead to the symptoms you have reported.
As a last resort, use tcpdump to observe the DHCP traffic between clients and the Mikrotik.
