Wireless network stopped working

Hi

Looking some help!

My wireless network is a simple omnitik u-5hnd supply 3 SXT 5HnDs. This has been working tirelessly for 7 years and all of a sudden it seems it will not pass on any IP addresses or be found on the network.

If I connect direct to the Omnitik u-5hnd with Winbox i can see it and the 3 remote ends and all settings look correct but when I connect it back in to my router it is not recognised.

It’s has me baffled but was wondering would a damaged cable cause this even though I can connect via Winbox direct?

Thanks in advance for any help

Which OS version does it have?
