DHCP does not assign IP to EAP225outdoor clients
Hello,
I have an AP eap225 outdoor and eap225, a DHCP Server in my modem 192.168.10.5 to 192.168.10.220, when i have a number >25 users, the other clients doesn't obtain a valid IP, so they can't reach the internet.
the APs are located in a coffe if that's matter.

Hi @ghost124
Here are some troubleshooting steps and potential solutions:
1. Check DHCP Lease Pool Size
- Your DHCP range (`192.168.10.5` to `192.168.10.220`) should support up to 216 IPs, which is more than enough for 25+ users.
- Verify that no other device (like another router) is also acting as a DHCP server and conflicting.
2. DHCP Lease Time
- If the lease time is too long (e.g., 24 hours), devices that disconnect may still hold onto their IPs, preventing new devices from getting one.
-Solution: Reduce the lease time to 2-4 hours*(or even 1 hour for a coffee shop with high turnover).
3. Check for IP Conflicts
- Some devices might be manually assigned an IP within the DHCP range, causing conflicts.
Solution: Ensure static IPs (if any) are outside the DHCP range (e.g., `192.168.10.1` to `192.168.10.4`).
4. Modem/Router Limitations
- Some ISP modems have a low limit on DHCP leases (even if the range is large).
Solution: Try:
- Restarting the modem (clears DHCP leases).
- Upgrading modem firmware.
- Using a separate router (like a TP-Link Omada router) for better DHCP handling.
