the situation with one of the wireless PtP links at work:

(the issue isn't RF absorption or anything, the issue is badly secured Cat5 cable that's probably not rated for outdoors, dropping down to 10Mbps whenever it snows)

also Real Networking Guys kept telling me that Ethernet devices and switches do not renegotiate link speed when the ethernet link quality is bad. I am very sure they do. it might be a nonstandard feature but it exists

(iirc Intel drivers call it "downshifting")

@grawity tbh it could just be a "link died, let's try negotiating again" cycle as well

@ignaloidas yeah but it specifically avoids advertising support for the highest link rate when that happens

(and once I bounce the switch port down/up, it negotiates 100M again)
