Model: EAP245  
Hardware Version: V3
Firmware Version: 5.0.5 Build 20220323 Rel. 68784(5553)

I have some devices on my network that cannot connect to the SSID of the EAP245.

 

Examples:

1) I have two brand new (setup phase) laptop from Dell, with an intel AX201, same driver version, same properties on all settings.

 - One can connect to the EAP245, the other cannot

 - The one that cannot, I can connect it to another SSID from an ASUS router.

 

2) I have a Realtek RTL8811AU dongle that I cannot connect to the EAP245 SSID

 - Tried it on 2 PC

 - The same Dongle can connect to my other ASUS router fine.

 

What I tried.

1) Removed some SSID (unused) from the EAP245

2) Upgrade the firmware

3) Multiple reboots

4) Changed the 2.4G channel to 6 (unused around my house)

5) Added a Syslog server to try to catch more logs, but that does not work!

6) The only thing I see that may be related in the logs on the EAP is this:

 WPA2 authentication times out/failed

 - But I don't see this message on every try

6) I see in the list of clients connected to the EAP245 the MAC of the RTL8811AU, on 5G, but it's with a 169.254.228.169 address.  So it's connected by cannot get a DHCP?

7) Tried other protocols (simpler) 802.11a only, b only, does not fix the connection issue.

 

I've exhausted what I can think of.

Any clues, tips, or things to try would be appreciated.

 

This is highly frustrating.

 

So it seems to be a combination of devices and AP.  But the fact the 2 identical network card/same config/same driver do not have the same behavior is beyond comprehension!

 

Thanks !

@Somnus

 

I'm not using any Vlan.

 

@Fae 

 

The issue was not in the EAP, it was the way the router DHCP range and lease time was configured.  I ran out of DHCP in an attempt to reserve all devices on my network.

 

I augmented the IP range to permit more clients, reduced the lease time, while keeping most of my devices with DHCP reservation.  I had to clear all old reservation on the router also.

 

Lesson learned!

 

Thanks!

  @SimonFili Is there any VLAN ID you set up for the SSID? It seems a DHCP issue.

 

Try remove all VLAN settings or move all SSID to the same VLAN, to see if it can work.

Dear @SimonFili,

 

Was the issue you reported here resolved finally?

 

If not, perhaps you may try to manually set a static IP address on your client and see if it would connect and work with the EAP245 SSID. If the static IP works, I'd like to escalate your case to our support engineer for further investigation.
