2.4ghz speed slow

Sethg103 — Fri, 16 Apr 2021 20:25:06 GMT

I’m having issues with the 2.4ghz network. At first when connecting to an SSID it says connected, no internet. Shortly after that it starts working, but extremely slow. Speed tests have it at .016mbps download and 1mbps upload. Using a wifi analyzer I notice the only channel it stays on is 11. I have a smart rf policy that has channel 1,6, and 11 for the 2.4ghz network but it looks like it’s stuck on 11.

I need some help getting the 2.4ghz network working. If I enable the same SSID on the same AP connected to the same port but enable it on the 5ghz radio it works great. Upload and download speeds are both about 200mbps.

Are there any other WiNG APs involved here or is this a standalone AP?

Is radio 1 possibly hard set for channel 11 in the AP’s Profile? (Device override?)

Eventually there will be more, right now I’m just testing it on a single AP310E. I just checked it’s device settings and there’s nothing hard coded into it.

I have AP7632s that have the same settings at a different building that work great on both 2.4 and 5ghz. I’m just having issues with the AP310E with the latest firmware.

What is the WiNG version?

I was mistaken I thought I was on the all downloads page but it was the download history page. I have Wing 7.5.1.3-004R, version 7.6.0.0 is out now that may or may not fix some the issue.

So smart-rf could be just doing its job and landing on channel 11 because it thinks it’s the best of the three choices….and maybe all three channels are bad in the area, but channel 11 is the least bad. (log output does show a channel change from ch1 to ch11 due to an interference recovery)

With this being a 310e, I’m assuming here that you have antennas attached. (Are the antennas that are connected to the 2.4GHz connectors 2.4GHz antennas??

Do you have another AP model you can use for testing in the same exact area as the 310e? If you do, how is the 2.4GHz throughput when it’s also operating on channel 11? (Force it to channel 11 if you have to)

Curious to see what the output of this is too:

Sethg103 — Fri, 16 Apr 2021 21:18:17 GMT

I do have antennas attached the model is Extreme Networks ml-2452-apa2-02.

I can try getting an old AP-6521 going to test that out for you and I’ll reply soon letting you know the throughput.

Here’s the output you wanted:

Re: 2.4ghz speed slow

Okay, so those antennas are dual-band, so no issue there.

The energy graph doesn’t indicate a problem with non-wifi interference...and it does appear that smart-rf selecting channel 11 makes sense based on the output.

Be very curious to see how the 6521 behaves.

Can you post the output of these while the client is associated?

Command 1:

Command 2:

It will still be a little bit before I can test out the 6521

Re: 2.4ghz speed slow

ckelly — Fri, 16 Apr 2021 22:42:46 GMT

Everything looks very good on those stats.

At this point, I’d still want to see how the 6521 compares.

Re: 2.4ghz speed slow

@Chris Kelly I plugged the old 6521 in, setup the ssid the same way. I don’t believe smart rf is being used on it, and it’s on channel 1 which seems to be used by a lot of wireless networks around here, I’m not sure how to force it onto channel 11 with the CLI. The throughput and speed works decently with 50 download and 50 upload. Even that would be acceptable on the new system.

Here’s those last 2 commands run on the 6521:

Command 2:

Sethg103 — Sat, 17 Apr 2021 01:51:57 GMT

And for reference this is plugged in to the same port the AP310e was plugged into. It’s also not adopted by a controller.

Re: 2.4ghz speed slow

ckelly — Sat, 17 Apr 2021 02:01:44 GMT

Okay...so as a last check, to get the 6521 to channel 11, in the CLI:

enable
self
interface radio 1
channel 11
commit

Re: 2.4ghz speed slow

Sethg103 — Sat, 17 Apr 2021 02:07:11 GMT

That worked, I can confirm it’s on channel 11 now. The speed / throughput is the same as when it was on channel 1. I’m at a big loss as to why the 2.4ghz is working so terribly on any of the 310e’s I have.

Re: 2.4ghz speed slow

ckelly — Sat, 17 Apr 2021 02:37:10 GMT

The only thing I can think of right now is that there’s something with the 11ax functionalities on the 310e that is causing this.

To test:

enable
self
interface radio 1
no 11axSupport
no 11axOFMDA
no 11axBSScolor
no 11axTWT
no 11axUmuschedBrcmOnly
commit

Test client again.

Re: 2.4ghz speed slow

Sethg103 — Sat, 17 Apr 2021 02:50:58 GMT

I ran those commands and committed them. It’s still having throughput issues.

Re: 2.4ghz speed slow

Sethg103 — Sat, 17 Apr 2021 02:53:06 GMT

Do you think upgrading the controller and APs to 7.6.0.0 from 7.5.1.3-004R would fix any issues?

Re: 2.4ghz speed slow

ckelly — Sat, 17 Apr 2021 03:07:57 GMT

Out of curiosity, what does the client connection speed indicate?

Even though speeds are slow, can the client get a consistent set of PING replies to the AP or something behind it?

I’m not sure what else might be causing this. If I had a 310 I’d try to replicate it. This isn’t something I’ve run across before.

At this point though, GTAC will need to do a deeper dive.

Re: 2.4ghz speed slow

Sethg103 — Sat, 17 Apr 2021 03:19:18 GMT

That was a good question. It looks like if I ping the AP from the client or even the switch behind the AP that packets are getting dropped, and the response time is high, 600-1000ms for some packets. HOWEVER if I run traceroute and ping commands on the AP pinging various devices on the network and internet the replies come back at a normal rate of around 1ms. It’s something weird with the 2.4ghz because it works fine on 5ghz.

I’ll reach out to GTAC. If we get it working I’ll reply with the solution in case anyone else down the road runs into this as well.

Re: 2.4ghz speed slow

ckelly — Sat, 17 Apr 2021 03:47:49 GMT

If you want, grab a copy of the running-config and strip out anything you don’t want seen and post it. I’ll look through it and see if there’s anything in the actual config that might have something to do with this behavior.
