Controllerless Networks

Hi all PROs

I use two IAP225-RW with firmware 6.5.4.4_62887

I sometimes note that my normally super good throuput (I normally get 700-900Mbit with a Mac book client) is gone. When that happens I get around 50-60Mbit. I see nothing that could cause this. Rebooting the APs solves the issue.

Q1

Are there any known issues with this firmware?

Q2

If not Q1... Are there anything special to look for when it happens next time so it could be tracked down?

Thanks in advance

- What is your regulatory domain?

- What band is your client connecting to when you have this issue?

- Are you running 80mhz channels?

- Do you have Broadcast Filtering set to ARP or ALL?

Hi and tnx for replying

- What is your regulatory domain?

Sweden

- What band is your client connecting to when you have this issue?

5GHz

- Are you running 80mhz channels?

YES

- Do you have Broadcast Filtering set to ARP or ALL?

Disabled

This happens very rarely. But even so, it is annoying.

Try setting broadcast filtering to ALL or ARP on all of your SSIDs.  If there is some wired broadcasts that is taking down your network, that will prevent it from propagating to your wireless.  Please also check that you are indeed on the 5ghz band when you are having issues.

I will check next time it happens that I am still on 5GHz.

So next time it happens, I could also try to turn on broadcast filtering and see it that solves it. Of course I could turn it on now as I have not managed to get the TV stream going over wifi anyway that was the reason for disabling it.

But... Why should an AP reboot solve the issue of it is broadcast related? Please enlighten me. what am I missing here?

Parentesis

Reason for broadcast filtering is disabled in the first place is that I have a case where I try to run IPTV over wifi. But IAP225 cannot handle the TV stream (Works when taking the TV vlan stream out on eth1 from the IAP225 though)... Probably due to IGMP problem or so. That is posted in another thread that never get solved. I probably have the wrong APs for that.... :) But that is as said another thread. 

Tnx in advance

Wired broadcasts cause degradation of wireless traffic, which is a shared medium.  That might not be the problem, but it will deal with other problems.  Many people who have sporadic wireless issues it is due to random, periodic broadcasts propagated from the wireless to the wired.

Sometimes the RF could be bad and the wireless broadcasts is what could make it unusable.  Turning on broacast filtering takes that out of the equation.

What is the bandwidth of the IGMP stream?

Tnx för the clarification. I will have that in mind.

What is the bandwidth of the IGMP stream?

Well... it does not matter if trying a non HD channel (i.e low bandwidth). I can only have the EPG from the TV vlan 21 on my TV SSID. The IGMP stream simply cannot pass out on wifi. But taking out the TV VLAN 21 on the eth1 port on cable from the AP to the tv box works. I now think the Aruba IAP225 is simply not up to the task....

But can you help me get it work I will give all the kudos in the world... :) :)

Turn on dynamic multicast optimization on your SSID and see if it will work.  that should identify your client as a subscriber to the stream and allow the traffic to pass..

It does not work.

However... The tread subject is not relevant for this. And as the streaming is a separate issue, I will do some more homework and sniff the traffic. And then post a subject relevant question with good info attached.
