Benefits of running 2 Wi-Fi networks from the same router? What are the downsides? (I don't know if there is a better community for this question) (discuss.tchncs.de)

I am worried that there is not really a benefit of doing that, just more noise and energy consumption.

Energy consumption is essentially the same, as it's using the same radios.

For what it's worth, I have several SSIDs, each on a separate VLAN:

my main one
Guest. Has internet access but is otherwise isolated - Guest devices can't communicate with other guest devices or with any other VLANs.
IoT Internet: IoT and home automation devices that need internet access. Things like Ecobee thermostat, Google speakers, etc
IoT No Internet: Home automation stuff that does not need internet access. Security cameras, Zigbee PoE dongle (SLZB-06), garage door opener, ESPHome devices, etc

(to remotely access home automation stuff, I use Home Assistant via a Tailscale VPN)

Most of these have both 2.4Ghz and 5Ghz enabled, with band steering enabled to (hopefully) convince devices to use 5Ghz when possible.

This is on a TP-Link Omada setup with 2 x EAP670 ceiling-mounted access points. You can create up to 16 SSIDs I think.

That was an amazing read. Thank you.

What do you say is the use case for separating guest Wi-Fi with the more "private" stuff on your network?

As far as I understand... Basically all communications, even inside a network, are encrypted... So I guess you do that to avoid someone trying to exploit some vulnerability?

I think the main benefit is that Guests devices on your network can't find and exploit your own devices.

If you don't trust the person, why give them access to your WiFi in the first place?

[–] [email protected] 8 points 8 months ago

You can trust the person, without trusting their technical skills, such that they haven't inadvertently installed malware on their own devices.
