Hi Pukkita,
I have same error and yes i have an airfiber on ether. do u know why like this ?
Thanks
Check first the usual suspects: cable, injector…
If those are fine, AF’s are known to inject its own radio tx signal back into ether if there are obstacles in front or near it, causing these FCS problems.
Lower Tx power if possible and check; if these go away, that’s your problem.
Has any radio been deployed recently at the AF spot? Check for nearby obstacles…
