AX150 unable to access wlan for day zero configuration

[boyan008]

Hello,

Ive bought 3 AX150 to spread out my network to get to diffrent location and also manage multiple wlan. But im having issues when connected to a router where the AP dosnt wanna boot so i can access it. At best i mananaged to configure the primary AP and when it restarts its stuck in a red gren blinking state and never goes into a solid green state or shows my newly created wlan SSID. 

I can confirm that from my router its been assigned an IP of my local network. ive also tried to assigne a static management IP and get it assigned with DHCP , but nothing seems to work so i really dont know where to go. 

The APs are commected to a local network of 10.x.x.x/27 network i also have another network but thats on a tagged Vlan 10.x.x.x/26

Check LED status - the kind of indication its setting up give 10min time to get access , then do the zero day config:

Zero day config :

Does the AP get power from different source or PoE - make sure you get enough power to AP.

try again factory reset and test it.

The unit should go from white to green blinking to green/red blinking to a non green blinking state. I only manage to get to the 2st stage which is the green/red blinking state. Those time i get pass after the day zero configuration its not broadcasting any SSID the device is permanently in a red/green blinking state.

Factory reseting will not initiate the device. I have a cabel modem going in the house, if i put it in normal DHCP i can access AP , as soon as i add it in a bridge mode and attach a router since the ISP one is really bad i simply cant initiate the AP's.

Ok so it looks like with some help packetsniffing and having the cisco mobile app i seem to have isolated the problem not sure if it applies to all class networks but a class C subnet of /24 make everything work, if you try to segregate the network to smaller networks it simply wont apply on the APs, they will still me stuck with a /24 subnet instead of the subnet your acctually using. Strange, not sure why either.
