Problems with wireless clients

[hcolindres]

Good morning, everyone.

We’ve been experiencing issues with our network. We currently have two 300 Mbps ISPs and 29 Meraki Access Points, each with two SSIDs: one for guests and another for organization members. However, users connected to the Wi-Fi rarely reach speeds above 150 Mbps and experience an average jitter of 40 ms on speed tests, even with only a few users connected. They’re noticing unusual instability in the network.

After running some tests, we’ve observed high interference among the APs, and when pinging a wireless client from the Meraki dashboard, the graph shows frequent spikes, with latency varying between 90 ms and 10 ms or sometimes more.

Wired Clients

As you can see, the wired clients’ graphs show stability and not many spikes.

The AP are connected to a MS120P and this MS120P is connected to an MX that receives the ISPs.

Could anyone help me understand what might be affecting the wireless clients? If additional network information is needed, I’d be happy to provide it.

Thanks in advance.

Extra: This is how Ookla opens when you try to do a test.

Wireless survey?

x 2 Did you undertake a wireless survey? There could be many causes, interference from other Wifi networks, AP placement the list goes on.

Do you have the wireless profile set to 20MHz channel width for 5GHz, or are you using 2.4GHz?

Do you have the AP power levels set to automatic, or are they manually set?

+1 for a wireless survey. There's really no substitute from a proper wireless survey being performed.

In the meantime, you can check some information around interference under Wireless -> RF Spectrum
