I am new to all of this and have been trying to find answers to my questions. I am a customer on a 900 MHZ. My internet drops on average about once per hour for about 5 minutes. When this happens I pull up the status page for the SM and the RSSI and jitter values dont move at all when being refreshed. I call the ISP and they cannot log in to my SM. They continue to insist that the SM cannot be bad. But there doesn’t seem to be any other explanation. My RSSI is usually 2600 or better and my jitter is 1 or 2. I am 0.22 miles from the AP. Please help, my ISP wont.
There could be a few things. First, do you have 900 MHz phones in your home? How about wireless speakers for your entertainment system? Both have been known to destroy 900 MHz installs.
Besides that there is a known re-reg issue which seems to affect 900 MHz a little more than 2.4, 5.2, and 5.7.
I would suggest asking if they are using hardware scheduler, if they are then it might be beneficial to go back to software scheduler.
The next time you are down you may want to run a spectrum analysis for about 5 minutes. To look at the spectrum analysis click on expanded status, spectrum analysis, then enable it. Every minute or so click on refresh (not a web page refresh but a spectrum analysis refresh)
If anything from 900-930 is red then you have an interference problem.

RSSI is 2600! Woof. Too much signal! What is the dB reading for that RSSI?
My RSSI is a little lower now. About 2400, the dB is -47 to -48. The ISP blocked all access to the SM so I cannot run any test on it. They are however running hardware scheduling. So I will try to ask them to change it.
thismail, Who is your ISP? I heard Lighthouse was using Moto, but I didn’t think they were that far down the EUP. We’re based in Alanson covering as far north as Levering. I’m currious who else is using Canopy so close to us.
Thanks
Lighthouse is my ISP. They now cover most of the EUP. Have you had any of your customers have any of the same problems?
Absolutely. We have had problems with Harware Scheduling ever since it was introduced. This is our first wireless venture and all of our wireless customers new that there may be some bugs to work out. Almost all of our wireless customer base was seeing exactly what you described. Switching to Software Scheduling made such a hude improvement, it was almost like magic.
We have a few customers that are pactically on top of the APs like you are, they have not re-registered a single time in the 4 weeks since we went SWS. Some people still re-register every now and then, but its more like 1 or 3 times a week instead of 20-30 times a day.
Hope that helps.
