isn't it wireless interface overload?.. why is latency so high?

when bandwidth throw that gateway aproaches the limit latency jumps really high

ping router <1ms
ping gateway <1ms
ping everything behind the gateway >1000ms

basically you are out of bandwidth correct? Time to buy additional bandwidth or figure out who's hogging the existing (and deprioritize it).

that would be nice but for various reasons this is not doable, my wireless clients are all throttled but i cant control some of the other users that are before the router. ideally i would get everyone to use a electric shock dog caller that translates bandwidth usage to pain.

changing the time out setting in the router os is the best way to deal with it.

your ping utility is the app with the timeout. routeros has no timeouts (other than qos buckets), it simply drops a packet if it can't fit down the pipe. if you need appearance of good ping times then prioritize icmp packets so they get first priority. deprioritize traffic that isnt so visible to users, ie smtp.

i am providing wifi in matiguas nicaragua this is a pretty poor place and quality of service is not so important, if a client has to wait 5 minutes for page to load thats fine

so i guess changing the qos buckets time out would be the way to go but h
