Address Table - who is connecting to my router?

[Jnorris235]

Found that where dozens of legacy devices connected to my home router. So I deleted all those that had no traffic shown and also had no name. There are two left and I don’t want to upset daughter and husband who are living with us. If I delete them, will they just reconnect happily when used, or will the owner know that I KNOW they have this device. One is an unknown phone (oops). EXTRA 1: Some devices have a colour on the left, some have a greyish colour - not sure what these mean. EXTRA 2: the usage shows 0 - but for how long is that for? (We’ve had power cuts and I have also restarted the router thru its admin - yet some devices show a lot if usage so that must be over quite a period of time then?)

Thanks

@Jnorris235 : 

1. What EE router do you have (read its label or post a pix)?
2. You could remove these devices from your router's connected devices list & they should reconnect quite happily the next time they are used. If it is showing thier MACs you could perhaps ID them using MAC Address Vendor Lookup
3. Greyed out device will be those not currently connected.
4. Usage will be since router was last rebooted..

Thanks. Pleased they wont know! Usage was showing large numbers even tho I’d just restarted via the admin. Obviously that’s not rebooted! Cheers
