Old Device that only uses 2.4 Ghz single-band wifi

Hi -

I have Mitsubishi mini-split HVAC system that is controlled by wifi on 2.4 Ghz single-band wifi, ONLY! I upgraded to dual band 2.4 and 5 Ghz modem so now the heating system can't be controlled.

Any way to add an additional 2.4 single-band wifi modem to my setup? Turning 5Ghz off the multi-band modem does not work.

Thanks!

So, I finally called the Verizon help desk. Turned out, they needed to something on their end to give me full functionality. I can now use my G3100 router with my old Mitsubishi mini split HVAC units (that only uses 2.4Ghz). I turned SON off and connected to the stand-alone 2.4 GHz signal.

Modem? Fios does not use modems. From your description, I think you mean the wireless router. Can you find the model number on the router? Is it a G3100 or a G1100?

Right, router. The new router is G3100. Can you help?

If SON is enabled in the 3100, try disabling it and give the 2.4 and 5.0 bands different IDs & passwords.

Thanks! plus reset modem. Tried that and didn't work. Old device says "connection failed". Do you think adding a "dedicated" 2.4Ghz router could solve problem?
