up the latency issue again new findings..
We are experiencing the same types of issues
all of the sudden.
Our setup is as follows, NOC (Router) ->
Motorola Canopy(NOC) -> Motorola Canopy (Hilltop) -> 5 port netgear
switch (Hilltop) -> 3 APPO's.
However our latency is all of the sudden
coming from the wireless side of our APPO's. If we ping from the
router to the access points we get 10ms or less round trip times. As
soon as we ping a client through the APPO from the router 100-600 ms ping
times and huge packet loss. Vice Versa, pinging from wireless
customer to APPO 100-600 ms.
This has just started happening the last 2
days. We have not changed anything in the last 2
months.
Have added more customers to the APPO's on
that hilltop, however are not over 30 bridges on any one
APPO.
Any help would be apprieciated.

Okay as you all know I have been having
latency issues when one or two people get on pings go thru the roof
100-600ms..
We ran a test from my partners house on
wireless. He faces are furthest tower which gets its backhaul from our
main tower 8 miles away. This remote tower he faces has 3 clients on it
right now and it has two APPO's one for backhaul (in client bridge mode)
and the other in Access point mode.
So we set up a constant ping to each radio
in the chain all the way to the main tower an noc.
1. Before starting the test we see <10
ms to main tower to the noc about 30 -40 ( all cause the
automatic 20ms+ latency the Motorola adds)
2. We start a bandwidth test and every
radio we ping stays at <10ms all the way to the main tower which
is good!!!
3. Now here is where we see the problem we
ping the radio at the tower that serves as the backhaul ( Motorola
client unit) the pings go way up to over 500ms at times????
anyone have any ides? all three radios at
the main tower are plugged into a dlink 5 port switch that has been
working great so I thought. I have the Motorola unit forced at 10 meg
1/2 duplex. I tried setting it to full and 100 and no difference? I
think I have found where the problem lies just not sure why?
Any help would be appreciated as to what
else I can try??
