WDS problems observed in today's testing

Just to add that: - The access point Javier mentions is the one I bought yesterday (Linksys WRT54G) - Most of this traffic is retransmission (3606): (wlan.fc.ds == 3 and wlan.sa[0-2] == 00:17:C4 and wlan.ta[4-5] == ce:6e) (wlan.fc.retry == 1) - It is also interesting to detect other wds peers

Kim, Michail, The conclusion to all of this is that we should not use WRT54G in deployments, regardless of whether mesh is used or not (in fact, if we *only* use mesh we don't have this problem as the AP ignores mesh multicast traffic now). The WRT54G will forward multicast traffic to all other
