Does a Guest SSID affect performance?

  • Question
  • Updated 3 years ago
In about a month we will install 4 Aerohive AP230 in our new offices, and I'm starting to set things up now to test. 

I read an review of Ubiquity APs in Ars Technica the other day that mentioned that having a Guest SSID in addition to your main SSID effectively halved the max transfer speed of your AP. 
Is there a similar problem on Aerohive APs as well, or is this a problem only for Ubiquity?

I understand there might be a little bit of overhead, as detailed in this article:

...but I'm willing to live with that for the benifit of having a separate SSID/VLAN for guests.

Hi There,

No problems encountered so far over here.
Just make sure you create as less SSIDs as possible to increasy Wi-Fi stability and speed.

I'll concur with Maurice, we have seen no issues and have up to 3 different SSIDs on our APs. You can drill down into the settings and restrict the speed of the guest network if you want.

Thanks to both, it seems like there is no problem on the Aerohives with this. As I understood the Ars article the Ubiquiti AP would "split in half" to serve two SSIDs, and i wondered if that was a common limitation.

There is not that problem with Aerohive APs. Having just one additional SSID will not by itself significantly consume or restrict access to airtime for associated clients.

Remember that the SSID is not coupled to the user profile that you apply behind the scenes to a client's association, the VLAN and firewall policy that you are apply are entirely independent.

You therefore need to be primarily concerned with the 'type' of SSID (using language loosely here!), the method of authentication for the BSS and other configuration options that apply to a BSS as a whole and affect clients.
