Hi Paul, Sorry missed your first reply: I've seen interference from FM radio cause issues with tower links due to interference. Ethernet and FM radio operate on about the same frequency. The other issue I've seen is sources of interference over long links ingress via DC injectors. If you have spare cables up your tower run, I'd try running power on one, then data on another. As a side note, are you using STP on your runs? I'd also suggest you stick to AUTO mode if you can. -Tim.

Hi Tim, just wondering if you can shine any more light on this problem ? We are running 100 FULL hard set on both devices and one of them goes to 100M half for some reason, changing the other side to auto and disabling/enabling the interface seems to resolve the issue, so I'm just wondering if you know what I could do to resolve this one so it doesn't continue to happen as you seemed to be hinting that you knew of an issue which was causing this ThanksPaul

Is this on a tower site? And are you using a DC injector?

Hi Tim, yes this is what happens. I think what I am seeing is that the side set to 100FULL at the moment is actually set for 100 half, but the side set to auto is setting itself to 100 full What's the best way to deal with this then ?
