2.4Ghz not working on hub 4

[Ross_E_Boy]

My hub 4 has no 2.4Ghz working. I've had this hub for a year now and it is only when trying to connect devices that only use 2.4Ghz I have realised it's not working. I am to believe it's a faulty hub as the router manager says 2.4Ghz is broadcasting when its obvious it isn't. I've done all the usual trouble shooting. Even a full factory reset to see if that has helped and this has caused 2.4Ghz to now transmit for maybe 5 to 10 minutes after a reset then disappears again.

5Ghz seems to work fine.

Any help would be appreciated

A few people have reported similar issues and its been put down to firmware gliches reverting it back. Try this (if you havent done it yet) and see if it helps
_____________________________________________

f you haven't done this already - try it first - it helps sort some Hub3/4/5 wifi issues for some devices.
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 “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 - Billybob2 & Billybob5) 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 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 Ross_E_Boy,

Thanks for your post and welcome to the community.

Apologies for the 2.4Ghz issues, I can't seem to locate any details from my side.

Has the service reappeared since posting?

Thanks,

[Ross_E_Boy]

No, only appears for between 2 to 10 minutes after resetting the hub.

Hello Ross_E_Boy, thank you for an update on this issues. 

So this issues is only lasting between 2 and 8 minutes and after this time there is no issues with it at all works fine?

Have you logged into your hub settings to see if the 2.4GHZ is activated?  Thanks 

[Ross_E_Boy]

No, the issue ensues after 2 to 10 minutes (roughly) after hub reset. After a reset 2.4 network appears (I have sperated 2.4 from 5ghz) then after a few minutes 2.4ghz network disappears completely and cannot be found/discovered from any device I try to join onto the network. Ranging from my laptop, multiple mobiles and smart devices.

Hi Ross_E_Boy

Thanks for coming back to us. When it disappears after the reset - have you logged into the router settings to see if it's there? 

Kind regards,

[Ross_E_Boy]

I have yes, and nothing shows up

Thank you for your reply Ross_E_Boy.

Can you please confirm when you last factory reset the Hub? 

If this was recently, and has not helped to resolve the issue we may need to look in to the equipment further and possibly arrange for a technician visit. 

Thank you

The last factory reset was a few weeks back.
