Fast5364 v.3.00 DHCP not working

chorpal — Tue, 03 Feb 2026 16:31:43 GMT

I have a Fast5364 v.3.00 which has been working as it should for 2 years or more, on Sunday my Wi-Fi connected devices began to display IP Configuration Failure on any of my channels or on my access points, this has spread to my hard wired devices also and the workaround I'm having to use is setting a static IP on all of the devices, with the exception of my Alexa's which I can't set to static, has there been an update or something as this is driving me mad?

Hi there @chorpal I'm sorry that you are experiencing such an issue with the service I will be able to look into this for you. In the meantime, can I ask you to restart your router by unplugging it for at least 30 seconds, then plugging it back in. Ensure all cables are securely connected and please let me know how it goes.

Hi Thabile, thanks for the quick reply, I have done that already and also did it again and left off and unplugged for an hour with no change unfortunately.

Thank you for responding. It is good that you have restarted your router my apologies the issue is persistent. Could you please confirm-

Are all devices failing to get an IP address automatically?

Does the router’s device list show connected devices, or is it empty?

@Thabile-TT I have done this already for 30 seconds several times and I also removed the power and left it for over an hour before reconnecting with the same results

I understand sorry once again, now that we know you restarted the router can you confirm if you are at home so we can run some checks.

Hi @Thabile-TT all devices are failing to pick up an IP from DHCP so I am having to set static IPs those are showing in the tables, yes I am at home if you want to proceed with checks

@Philile-TT the router gave up the ghost just after your colleague said he was going to help, fortunately I have an old spare that I'm using at the moment that seems to be holding up, that said I spoke with Customer support yesterday who are sending me a replacement as I've upgraded my package, so fingers crossed I should be able to limp through until it arrives, I have a number of devices that I have reserved and if I remember correctly you guys had to push a firmware mod to open it up to allow me, is this still the case?

Okay thank you for the update. Please let us know when you receive the new router. You can try that.
