I’m having some issues with a B11 link that has been working fine until the temperature got bitter cold a week or so ago. PHY rates were normally solid but are now all over the place. Switching my link from 80mhz width to 40 helped quite a bit, but when it gets very cold (-25 degrees) things still seem to go south. I’ve attached a screen shot showing the correlation between temp and PHY rate. Anyone else running B11s in the cold?
