Please can a Three moderator advise on the following issue. We have had 5G mobile broadband for around 6 months, with limited issues. However since overnight Thursday 13th July, we are now having multiple connection issues with devices around the house that had previously been fine.
Specific issues include a SONOS setup that refuses to connect (it simply fails on the app once the wifi password is put in), an older Alexa device that again refuses to connect citing that it does not recognise the password even though it is correct (2 x other Alexa devices work perfectly), and a wireless printer that returns error messages when a job is sent to it but then roars in to life 15mins later... All worked well until last week as described. Laptops, phones and smart TVs also appear unaffected.
I have factory reset the ZYXEL hub, and can confirm it is running b14 firmware. Speaking to Three's webchat, they suggested they had manually refreshed settings their end but this has not resolved the issues - only the printing worked for 10mins before now being intermittent.
It is too much of a coincidence that all of these devices stopped working on the same evening, although with my admittedly limited knowledge, I can't see any issues in the router settings that would lead to such issues. Therefore it feels like it has to be something faulty behind the scenes or with the hub itself? Please help, and thank you in advance!
