Old Device that only uses 2.4 Ghz single-band wifi

[tonygba]

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!

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?

[tonygba]

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

[dexman]

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?

[Cang_Household]

G3100 has a dedicated 2.4 IoT SSID. You can enable that and connect your IoT to that.

[tonygba]

Tried the IoT, but my device couldn't find the IoT wifi name?  do i need to change any other settings?

[Cang_Household]

What do you mean it couldn't find the IoT name? Can you find that SSID in other wireless devices?

[tonygba]

when i look for wifi names, the IoT name does not show up on the list... when i type it in directly it say can not be found.

[Cang_Household]

Then you have not enabled the IoT SSID. Can you screenshot the home page of G3100? Of course with passwords hidden.

[tonygba]

here is the IoT wifi name...

[Cang_Household]

The screenshots indicate the wireless settings are not written to the flash. You need to enable and disable IoT and WiFi to tweak it right.

[tonygba]

Interesting!  simply Disable the Enable again?  what do you mean "written to flash"?  I think I am almost there!!

[Cang_Household]

I think you need to play around the IoT and WiFi settings. Flash is a storage medium built into the router. The router can read settings from it.

[tonygba]

ugh... i thought i played around with them all!...  I will do a factory reset and start again.  Thanks anyway.

[Cang_Household]

Don't do factory resets. Starting working on what you have. Factory reset may not wipe out the entire flash and may cause setting conflicts.

I know regular tech support would perform reboots and factory resets as first steps, but starting afresh without identifying root causes is rarely helpful.

[tonygba]

ok.  i'll keep plugging and chugging!

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.

Ive done the following and I still can't get it to work. 

-split 5 and 2.4 out

-changed their names and passwords to two different names and passwords-

-changed the IOT name and password

-verified that Parental controls arent on

I can't find any information on what I might be missing.
