Yesterday, I noticed a pattern where several 450i APs experienced multiple Ethernet interface “flaps” — for example, counts like 49 flaps in a short window — across different sites. These flaps appeared to coincide with the recent geomagnetic storm activity. Interestingly, at the same sites, legacy 450 (non-i) APs did not appear to show the same behavior.
While I haven’t completed a full analysis yet, the pattern was fairly consistent across multiple locations: 450i APs were affected, often with similar flap counts, and then the issue would subside, possibly returning later — again seemingly in sync with geomagnetic storm intervals.
I’m curious whether anyone else observed similar behavior, particularly with 450i devices or other variants in the 450 platform (e.g., 450m, 450b). Did you see interface instability that might line up with this timing?
Not looking to draw conclusions yet — just gathering data and observations.
Yep, it’s definitely a thing. From what we’ve seen, it’s 100% related to the solar storms we’ve been getting over the last couple of years. Our sites usually have 10 m Ethernet runs, which makes the behavior even more interesting. I suspect trying some higher-grade cable might help, but I haven’t spent more time digging into it yet. - Mix of ubiquiti/netonix/cambium.
At this point all my installs for APs would be seldom Cat5e shielded cable and more often Cat6 with shielded ends, the APs grounded, inline Transtector OEM’d 1 Gbps rated lightning arrestors with better solutions to keep the door properly shut and more often than not Tycon DC to DC power units that are also grounded as most my sites do not have AC and run directly from large battery arrays. I know Cambium now recommends those units where the shielding is exposed and then grounded with kits that are supposed to make the cable watertight again. Perhaps that would help. More information from others would be helpful.
