While connected to the same AP."</P> <P style="margin: 0;"></P> <P style="margin: 0;">Could you check if everything is fine on wired network side? Like congestion on switch or high broadcast/multicast from wired to wireless or vice-versa?</P> <P style="margin: 0;"></P> <P style="margin: 0;">You already did a lot of troubleshooting so I think opening case with these observation will be more helpful to debug the issue.</P> Tue, 24 Nov 2020 21:51:50 GMT https://community.ruckuswireless.com/t5/ZoneDirector/R500-with-ZD1200-10-4-1-Low-UL-DL-Intermittent-issue/m-p/17662#M3751 syamantakomer 2020-11-24T21:51:50Z
