Wireless internet keeps dropping out on a Smart Hub 2.

Hi Hi,

So I've got BT's full 1gig internet with a smart hub 2.

It's been working perfectly fine with the frankly ridiculous amount of internet enabled things in my house since it was installed last year.

Up until this week where any wireless device connected to the thing drops pretty constantly, 2 - 3 times a day.

So far I've tried setting the 2.4ghz and 5ghz bands to run on different channels incase there was some sort of interference on them, I've soft reset the router a few times, I've unplugged and plugged it in a few times and I've just hard reset it with the little reset pin on the back, held it down for 30 seconds until the lights turned green and so far nothing seems to have fixed it.

I also have 2 computers connected via ethernet and they have been fine up until today where my work PC has been struggling with connecting to the internet.

I ran the troubleshooting tool on the BT website and it just told me to enable smart channel switching.

Any ideas?

It might be worth doing a factory reset on the home hub, but if you have any digital voice handsets paired to the hub, then backup the numbers first.

A common problem with all of the home hubs, is that they run out of internal connections if you have any devices that use a randomised MAC address, sometimes called private addressing.

Each new MAC address takes up another IP address, and soon you can run out of connections. You will see lots of "Unknown device" entries on the home hub network map.

A normal restart can help for a while, but only a full factory reset clears out all the old entries.

If you have any devices, both wireless and Ethernet, that have MAC randomisation turned on, then turn it off so that only the device MAC address is used. That will ensure only one IP address is allocated for that device.

Then do a factory reset, and see if the problem returns.

I've just factory reset the router now, hopefully it sorts the problem out.

Gives me the weekend to see if it sorts the issue or not before giving BT a call.
