Wi-Fi issues after splitting bands (unable to send messages on certain apps)

Hello there,

 

I have a bit of a strange one here. Originally I had all of my devices connected to the same SSID, which I believe connects the device to a band depending on compatibility? But since I have a few smart bulbs that use the 2.4Ghz frequency (that moaned about not being able to find the 2.4Ghz frequency) I decided to split the bands by giving them two different SSID's in the config.

 

Every device seems to be fine (wireless desktop, smart bulbs, security camera & alarm system), however my mobile device (regardless of whether it's connected to the 2.4Ghz band or the 5Ghz band) will always allow me to use the internet in general (browse the web, watch YT videos etc) but it refuses to send messages on apps like Instagram. I get error messages like 'failed to send, retry?'. Switching off the Wi-Fi and using data fixes this immediately.

 

I'm wondering if this could be a case of setting a static IP for the 5Ghz band or simply choosing a fixed channel (one that's relatively unused)? I know there are apps for detecting the best channel and the such.

 

Any help is greatly appreciated.

Hi CCoplestone,

 

That's strange, don't recall anyone reporting this issue before. Have you tried combining the bands again just to confirm that it does only happen if you split the bands?

Hello there @OCE_Chris,

 

It seems to only happen when splitting the bands. Unfortunately I need them split since one of my smart bulbs moans about the access point not being 2.4Ghz when they're 'combined'.

Hi

 

Do you know if this affect both bands or just one ?

 

For example if you split the bands and test a device on 5ghz, then forget this network on the device and connect to the 2Ghz and test again, does the device fail on both or just a specific band etc.

 

Thanks

 

Karl.

Hi @OCE_Karl,

 

This happens on both bands unfortunately.

Could you add your TalkTalk landline telephone number to your community profile and we'll check that your router is running the latest firmware

 

Thanks

Hi @OCE_Chris,

 

Thanks for the reply. My landline number has been added to my profile in the 'Alternative number' field.

Thanks for that. I can confirm that your router is running the latest firmware version. Do you have another router you can test with?

Hi @OCE_Chris,

 

Thanks for checking that.

 

Unfortunately since I've just moved out, this is the only router that I have in my possession.

I can send a different make and model of router to test with - would you like me to arrange this?

Hi @OCE_Chris,

 

If it's no bother then that would be fantastic.

 

Thanks for that.
