Hub issues - random WiFi outage

[timcymru1982]

Afternoon, I have a hub 3. We've been getting intermittent WiFi drop outs for a couple of months now. It's usually 1 device at a time, so the rest still work. This ranges from smart phones, Alexa devices, Xbox etc. We've also had issues with streaming Netflix and Prime. The picture becomes distorted or simply stops quite frequently which should happen with a 200mb connection. I tethered my firestick to my phone yesterday when having issues trying to watch Prime and it worked fine. My son's Xbox cannot connect to the router, however can connect to my phone. I'm guessing there's an issue with the router broadcasting WiFi. I've done all the usual, reset router, reset devices etc. Any ideas?

Look at getting your own WiFi router with 1Gb ports and use the hub in modem mode....or you can go down the long path.

BEFORE doing that, it may just be a problem with the signal to the hub itself.

log into hub3 -

Here : 192.168.0.1 - DON'T SIGN IN, click - click router status [centre of screen] - and post the config figures - to see those press on the grey buttons/boxes labelled - configuration

You can also think about setting up a broadband quality monitor from think broadband.

(It's the little graph in my signature)

I already setup a monitor, most days look like this. Pretty sure the connection coming into the house is fine, it's the wifi in the house that's the issue. Thank you for your help by the way. Tim

It very well could be, and you can just go out and buy a big fat wifi6 router/mesh.

But I think it's worth checking this before you drop £200 for it.

Can you post all the stats from every tab please?
