Thanks for your response, Scott.
Fast lane has been always on. I have another SSID for IOT, where everything is basic and it's pretty much the same experience.
The approach you're suggesting is absolutely fine, if we consider this is a green-field implementation so starting fresh/from scratch makes perfect sense. The problem here is that this setup has been running for 2+ years now and I only recently started experiencing this problem - no changes have been done whatsoever (other than changing the OS and trying to turn some knobs off/on as part of the troubleshooting).
it is most certainly not the case. No errors reported on the switch (other than a very few output discards (which are quite typical for the 2960s)) but there is 4x1G LACP port-channel between the WLC and the switch .. :|
to be honest I have never experienced any similar problem with LAG/LACP and I don't see how any of that could have caused buffering/increased latency, but I still tried to do pull 3 members of the Po and leaving on single iface only and it didn't make any difference..
Does anyone know if I can somehow drop into the bash or at least get some output results from the WLC's kernel for the queueing? I found a way to check routing entries, iptables, etc, but what I'm really curious of is checking the 'tc' (traffic control) settings.
Here is all the outputs for all the APs.
The one I am using right now (probably the most) is AP3
Hi gents, me again!
I have again decided to spend some cycles on that annoying issue. I have figured out one thing - upload form my laptop is okay whereas the download (even from the local network) is crap!
I did the most basic test possible running iperf with UDP (to avoid any latency related issues/TCP) and the result is as follow:
Upload from my laptop to local server: 890Mbps
Download form my laptop from the same server: 25-40Mbps (with loads of drops)
It's just shocking! Check out the results.
Do you guys have any idea what could eventually explain this behaviour? I've seen quite a few topics here about slow download/fast upload, but nothing's quite like the issue I've got... I don't thing there is any difference from RF perspective whether the traffic is from/to, but I am opened to any suggestions ...
hm, I will try this but will this be the case for every phone/tablet/pc/mac that I have at home?
To me it seems to me something with WMM but there is only so much I can see about it on 2504 :/
very annoying... I will try to manually use one channel only & will let you know.
