Controllerless Networks

Hi all, 

we are using 6 nos of IAP-105 for corp wireless. 

that was working fine but from somedays users are faceing slowness .

 

soo can anyone tell me what are the troubleshooting options for the above scenario.

 

Note: i upgraded the iaps to lwtest firmware   6.4.2.3-4.1.1.2

What is the total number of users on the IAPs and how many SSIDs are you broadcasting?

 

Do you have Broadcast Filter All enabled?

 

3 ssid is there.

 

20-25 users average.

 

yeah broadcast filter all enabled.

What kinds of clients are having these problems specificially?

Is the slowness to the internet?  What is the internet speed?

 

all types of user are facing these problem [slowness in internet, while the connection is 35 mbps]

 

your switchs are 10/100 or 10/100/1000?
your master is connected as 1000 in eth port ?

check your log security , via ssh
what is your noise levels ?
band steering is enabled ?
clientmatch is enabled ?
are u using wide band in 2.4?

Hi Suman,

 

Can you share some more info, such as, 

 

1. which Clients are facing issue ? connected to 2.4 or 5 GHz 

2. Clients connected to any AP are facing the issue or all APs

3. Are these IAPs sharing BW with the wired users ?

4. Did you enable Client match ?

5. Did you configure BCMC properly ?

 

Please share the required information. I can help you on this.

 

Please feel free for any further help on this.

 

Hi kdisc98,

my switch is 10/100/1000.

 

1. both the 2.4 and 5 ghz are facing this issue.

2. client connected to all ap.

3.they sharing B.W with wired users, bt now all are connected to wireless, they dont use wired much.

4. yeah i enabled client match

5.i dont know where to configure BCMC.

 

If your suffering from the issues in 2.4 & 5 - are u sure your switch is working as 1000 ? are all the leds on the AP's units are green (or some red?)

When u facing slowness,is it to WAN - internet or to LAN - inside?

BCMC - is on your SSID / Adavanced (look on the left middle bottom - you will notice it)

WAN-internet. LAN internet is ok

SO , LAN is working fine...Your slowness is only on the WAN side... did u got MRTG (monitoring)  or conumstpion record? to understand if consume all your Bandwith?

can you please explain me how to do that..

Very stimple :) Contact your ISP,Check with them how much you consume from your WAN bandwith.

OR - install 3rd party router/GW monitor and check how much traffic is going to your WAN side.

 

 

ok, i'll give a try and let you know.

I did a ping test and the packet loss is around 20%.

 

now i become clueless...

SumaN a ping test what? we can't read your mind. did you do this before the slowness started also? perhaps it has always been like this.

if you want people to help you and work with please explain clearly and fully what you are doing.

so just some thing to think about, you mention slowness for all users since a few days. how did you determine this, have you actually seen data or are the users just saying it is slow.

is the wireless traffic to the internet go over the same router / internet uplink as the wired?

go on location and perform some simple tests. i.e. a speedtest via the wireless network and via the wired network. make sure you are only wired or wireless. browser the internet and see if you experience this slowness. you can see if a browser plugin or F12 to see if there is more slowness. this can be tricky because it might be the site or the connection.

Thanks boneyard for your response.

 

below is the list what i did to spot the actual issue..

 

i pinged the default gateway and vc [ from a device which was connected wirelessly]  and shocked the avg response is around  150ms

 

also i pinged the gateway and vc from a wired connected device and the avg response was only 2ms.

 

they have MPLS [100mbps, so no question about wan side issue] and all was working fine on wired.

 

Before that the never faced that issue. and there wireless was extremly fast. [IAP 225]

 

So i confirmed that the issue is on wireless, after that i found that they was suffering from interference issue.

 

So today i went there and disable some of the unused SSID, increased the immunity level, and made that wide channel bands as none.

 

Now the things are looking good.
