losing broadband connectivity on some but not all devices

[Tmouse58]

Hi,

Please can anyone offer a solution to this ongoing issue?  We have the BT Smart Hub 2 and we are losing broadband  connectivity with some but not all of our devices on a pretty regular basis, those affected are an iPad, mobile phones and television. The only way to get everyone back online is to reboot the router and it always needs doing at an inopportune moment, anyone have an idea as to what might ne causing this and how I can go about resolving it? Thank you

Try a factory reset of the hub to clear out stale connections. If you have MAC randomisation enabled on any of your devices I advise disabling it.

Just to add to @licquorice comment about MAC randomisation - Apple call it Private Wi-Fi Address btw .

Everytime a device that has this enabled connects to the SH2 it makes another entry in the SH2's IP address table and eventually fills that table so no more connections can be made and only a reboot clears this table.

Many thanks for your reply, I'll give that a go and let you know how it goes

Morning,

Many thanks for your previous replies, I have tried to do a factory reset but for whatever reason I can't get the router to do so. It goes back to a green light, then reverts to the blue and all devices connect without me needing to log in to each one. I have tried pushing in the button for 5, 10 and up to 30 seconds but on each occasion the hub lights don't flash.

Hi @Tmouse58 

It should only take a five second button push to factory reset. Are you pressing the button whilst the hub is still switched on?

from personal experience it takes nearer 30secs of holding the recessed button on back before lights flash and hub resets back to factory settings

I stand corrected. Thanks @imjolly 🙂

Morning,

I managed to get the factory reset done ok however the issue of non-connectivity is still there and it appears to be affecting the iPhone & iPad only. Is there something I should be adjusting so that I don't need to keep rebooting the router regularly? Thank you

Disable MAC randomisation (Private Addressing), see earlier post.

Its a setting on the Apple wireless options.
