How do I get a device that only supports 2.4ghz to connect to my hub 2 router?

[#1]

Hi,

I have a Samsung robot vacuum that is Wi-Fi enabled but is only compatible with a 2.4ghz band.

my hub 2 router is dual band  I believe, so presumably should be compatible with a 2.4ghz only device.

I have tried connecting the robot vac to my Wi-Fi but it doesn’t want to know.

Any ideas how I can get it to connect?

Thank you

In what way does it "not want to know"?

How is the robot made to connect to the WiFi?  Does it have a display screen?

What model?

The fact that the router is dual band has nothing to do with the connectivity of the robot only working on 2.4gHz.  How old is the robot?  There is a slim chance that the robot only supports "b" mode WiFi or WEP security (which are ancient).

What is the wireless mode setting on the router's WiFi advanced administration screen?

As I understand it you're not the first to have this problem.

What you do is turn off 5ghz WiFi in the Hub2 management page, connect your 2.4ghz device and once successful turn the 5ghz band back on.

Hi,

The robot is brand new.  It’s a Samsung Jet Bot VR30T80313.  It connects via the Samsung Smart Things app.  Whenever I try to connect it I get the message that the internet connection can’t be found and broadband may not be working correctly.  

The wireless mode setting is mode 1.

This is the blurb from the manual about the Wi-Fi requirements

Please refer to the user manual of your wireless router for the settings of the wireless router.
