[WISPA] Strange Symptoms
I have a system - Mikrotik 5.8 in on SR5 / 2.4 out on SR2 with currently one customer on it. He's seeing occasional REALLY high latency through his device (High Gain Antennas 8186hp @ 100' away from the POP) - like 900 - 5000 ms pings and some time-outs. I'm on what Mikrotik is telling me is a relatively quiet channel (3 to 5 devices at an average of -90's noise floor) and yet his network connection just flaps like crazy because of the latency. Can't run nstreme because of the devices I'd need to have connected (it's a hotspot on a rooftop) But, I'm perplexed as to why this is doing this. A drive up to the hotspot with my laptop produces the same results, as does a test from one of his other computers with a wifi card in it. Things to look for / do ?

History? Did it ever work? Distance? 100' from the POP? The signals are too "hot". jack Rick Smith wrote: I have a system - Mikrotik 5.8 in on SR5 / 2.4 out on SR2 with currently one customer on it.

Re: [WISPA] Strange Symptoms
Have you looked at it with a spectrum analyzer? I see this type of behavior in a high noise environment. Does it persist through all channels?

What board are you running Mikrotik on and do you see any latency on the 5.8 side? -Original Message- From: Rick Smith [mailto:[EMAIL PROTECTED] Sent: 12 March 2007 20:28 To: 'WISPA General List' Subject: RE: [WISPA] Strange Symptoms yep, no matter which channel. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sam Tetherow Sent: Monday, March 12, 2007 4:21 PM To: WISPA General List Subject: Re: [WISPA] Strange Symptoms Have you looked at it with a spectrum analyzer?

Re: [WISPA] Strange Symptoms
Rick, The signals levels sound like they may be WAY TOO HIGH for this short of a link. Receiver overload has the effect of making a receiver "deaf". Try a tiny antenna (maybe a rubber duck) on the CPE and re-do the ping test. jack Rick Smith wrote: yeah, 100' away from the pop. across the street (dead side street, antenna way up above car level) This is the first week we had this customer connected - and they're the first on the repeater... -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jack Unger Sent: Monday, March 12, 2007 1:24 PM To: WISPA General List Subject: Re: [WISPA] Strange Symptoms History?

Receiver overload has the effect of making a receiver "deaf". Try a tiny antenna (maybe a rubber duck) on the CPE and re-do the ping test. what dB level would you consider too high? We're seeing some of our 900 radios "recycle" and others just don't yet the signals are in the -80s and -70s. Nothing consistent.
