No 2.4g WiFi on hub 3

[Kme77]

I've had intermittent issues for months now with my hub 3. It periodically stops working on the 2.4g WiFi (5g unaffected).

It is very inconvenient as I have a lot of connected devices on the 2.4g channels and the only way to fix it has been to factory reset and set everything up again.

I tried saving the settings last time and reinstalling that settings file the last time it happened but that didn't work and only a full factory reset worked.

It has happened again but this time even a factory reset doesn't fix the issue and I'm stuck with only 5g and most of my devices unable to access the internet.

Could an admin please help me out in getting my hub3 replaced?

Thanks.

Have you tried separating the 2 bands - if not try it this way..
___________________________________________________

Go into the Hub’s settings. Type in  http://192.168.0.1  into your web browser’s url box and login with settings password on the Hub's base sticker (or your own if you changed it). Then in Advanced>wireless signal >smart wifi - tick the disable “channel optimisation” box or the“Smart Wifi” box and save settings.  May be different pathways and wording on the 3 Hub types

Then, go to advanced>wireless signal>security, rename the 2.4 & 5 GHz network ssid's.  Just type over to change 'em to whatever you like and something that will differentiate them (e.g - Kme_ & Kme_5). Try to avoid spaces and periods in the SSID names as they can cause issues with certain devices. Use the same password for simplicity,  Then, apply settings and restart the Hub.  Your 2 wifi networks will now be clearly separated - and you can then select the network you want each device to connect to… individually from the "available networks" list on each of your devices. 

Note all your wifi devices will need re-connecting to the new SSID's and passwords.
All things being equal, 5 GHz is always better/faster and subject to less congestion/interference (and is better for iDevice speeds than the 2.4 one - although the 2.4 one has the better "range" and will be needed when the 5 GHz drops out of range and some older/cheaper/dumber or “specialised” devices can only use this one. 

You should also use a wifi analyser App (or Airport Utility on iOS) to check which 2.4 channels are being heavily used around you and move yours to one of numbers 1,6,11 that is least so, but it wont help if there is other interference.

See if these changes help - you will lose any “seamless roaming” benefits but it may not matter and you can always change the settings back by doing a " pinhole factory reset " if you prefer the way it was - or it doesn’t help.

Hi, (unfortunately) this is already how I have the bands set up.

Thanks for the suggestion though. 👍

Our Hub 3 has only once not started the 2.4Ghz service after a reboot.

The menu showed 2.4Ghz as enabled - using a WiFi analyser confirmed no signal transmission.

By Disabling 2.4 Ghz and then clicking "Apply changes"
and a few minutes later Enabling 2.4 Ghz and then clicking "Apply changes"
the 2.4 Ghz service was restarted.

If it does not work or often goes down a defect could be the conclusion.

I have tried cycling the 2.4g channel in the past but don't normally leave it a few minutes, I'll give that a try thanks.

But it definitely happens far too often (not even after a reboot) so I'm convinced it's a hardware issue.

One can see that after clicking "Apply changes" the Hub 3 refreshes the WiFi settings screen quickly.

But using a WiFi Analyser we see the Hub 3 plods through the process of shutting down its WiFi services, making the changes and resuming the WiFi services, it really can take 2 or 3 minutest to complete a task such as a channel or bandwidth change.

I was allowing time for these kind of hidden events to occur.
