Re: [smartBridges] Bringing up the latency issue again new findings..

They are not Canopy Access Points.  It is a Canopy Backhaul unit with the Timing Master on our NOC roof, pointing to our hilltop 5.30 miles away connected to another Backhaul unit (Timing Slave) both ends have reflectors (dishes).   -TJ ----- Original Message ----- From: Blazen Wireless To: [EMAIL PROTECTED] Sent: Wednesday, November 19, 2003 10:29 PM Subject: Re: [smartBridges] Bringing up the latency issue again new findings.. Hey whats your setup on the canopy stuff is it the PTP backhaul unit or just the AP with a client unit at the tower? I want to know how you are getting 10ms or less???   Thanks   ----- Original Message ----- From: TJ Burbank To: [EMAIL PROTECTED] Sent: Wednesday, November 19, 2003 7:39 PM Subject: Re: [smartBridges] Bringing 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.   TJ Burbank Last Mile Wireless ----- Original Message ----- From: Blazen Wireless To: [EMAIL PROTECTED] Sent: Wednesday, November 19, 2003 8:19 AM Subject: [smartBridges] Bringing up the latency issue again new findings.. 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??   Here is a link to a rough pic of what I have set up http://www.blazenwireless.com/system         Martin & Steve Blazen Wireless 909-326-5003 www.blazenwireless.com
