Hi people,
Maybe you can help me with this problem.
We have two clients that are exhibiting some strange issues:
Client 1
---------
200 feet away from our tower. Power reduced to minimise interference. Using NAT. Clients are heavy Citrix users. Almost daily they are getting intermittently high ping times for a period of time. The SM must be rebooted and all becomes fine. Replaced the SM, still the same problem. Running latest firmware 7.3. Frequency locked onto 1 AP
Client 2
---------
20 feet away from our tower. Again drastically reduced power. Using NAT. Clients sometimes cannot browse for a few seconds and then again everything returns to normal. Latest firmware again. Frequency locked onto 1 AP
Any ideas as to what I can try doing?
Thanks
How do you have your ap configured? How many customers are registered?
What is the RF signal level on the SM’s?

The APs have very few users registered. maybe 4 users. We only just started our service.
What configuration settings are you after? They are on HW scheduling.

One customer has this:
Session Status

Registered AP
0a-00-3e-50-04-9e
RSSI
2053 (-35 dBm)
Jitter

Air Delay

The other customer has this:
Session Status
REGISTERED
Registered AP
0a-00-3e-50-04-9e
RSSI
1334 (-44 dBm)
Jitter

Air Delay

1.Do you have all your ap’s configured the same?
2.are they on a different color code?
3.Do you have a cmm?
4.Do you have each ap set to the correct freq’s
5.Have you ran a link test from the sm to make sure you didn’t turn the power down to low.
6.under sessions in the ap what is the power level for the clients that are having trouble
Downlink Data 75 %
High Priority Uplink Percentage1 %
Total NumUAckSlots 2 (Range: 1–7)
UAcks Reserved High 1
NumDAckSlots 2 (Range: 1–7)
DAcks Reserved High 1
NumCtlSlots 5 (Range: 1
1.Do you have all your ap’s configured the same?
Yes they are
2.are they on a different color code?
The 6 APs on the same cluster have the same colour code.
3.Do you have a cmm?
Yes I have a CMM Micro
4.Do you have each ap set to the correct freq’s
Yes they are correct
5.Have you ran a link test from the sm to make sure you didn’t turn the power down to low.
Both SMs report a 100% Link test both uplink and downlink.
6.under sessions in the ap what is the power level for the clients that are having trouble

2.are they on a different color code?
The 6 APs on the same cluster have the same colour code.
Each AP needs to have different colour code, change that, and also if you can post the freq used on the 6 AP.

Why do you need to have each AP on a different colour code? I have set the SMs to only connect to the frequency on the AP I want them to so there should not be any re-reg going on.
The frequencies are as follows:
Array A1 5495
Array B1 5520
Array C1 5545
Array A2 5495
Array B2 5520
Array C2 5545
Thanks
Canopy modules radiates around, not only to a 60-degrees sector (the front radiation is just more powerful). Your SMs can listen and talk to 2 APs at the same time - A1 & A2, B1 & B2, C1 & C2. Look at the AP Eval Data page on the SM.
Set different color codes.

So A1, B1 and C1 should have colour code 1 and A2, B2 and C2 should have colour code 2 ??
The unique color code for each sector is more preferable.

I see, and how would you know which colour code to set your SM to? When you are on site it is not easy to know which AP you need to connect to.
It’s seems harder than it is. you can use a map, there are other ways once it is registered if needed you can change the color code in the sm without a truck roll.
It is best to have all different color codes, and leave all of the freq’s checked in the sm unit.
Oh and keep it simple we use the same password for all customer radios
of course we don’t allow customer any access
The same way we do.

OK, if you don't know which colour code you should use, is there a way that the SM can scan and find the best AP to connect to and then you can decide what Color code to assign the SM to?
It is not a problem you are worry about. Use an area map as clueless propose. We use a map too and never mistake in a sector definition.
At least you can try all the color codes one by one when installing a SM. There are just 6 choices

True but if the SM is close enough (as is the case with our two clients) they will still register with another AP because of the radio spill.
SM registers only at the AP with an appropriate color code.
Yes they will register to the wrong ap, in the alinment part of the sm it will show you all the ap’s choose the strongest one.But Kaa is right get a map use a compuse if needed ,mark it in 60 degree from each ap you will be fine, you can change it later if needed from the luid section of your ap
I would also turn the power down further on the closer units. keep turning them down until you don’t get %100 on your upload test, then take it back up a little.
We average around 60 under sessions of our ap for our sm units, you are still at 40 on one and 51 on the other this will hurt you later as you add customers that are at a greater distance.
