thanks for reply, yes it appears so on a sky front. you used to be able to get the credentials via wireshark etc however some sites do say on MER / Fibre generic details work - all very confusing.
The Z3 primarily was to get some inteligence over my home network ,and control. We are gearing up with Meraki head ends at work etc but i've not got that far yet - it was more to get used to the dashboard, help home diagnosis and add security / prioritisation etc.
Ive ordered a BT VDSL modem so am hoping I can find the details or the genric ones work - then ill replace the sky router and use the Modem into the Z3. it does mean my Sky mesh will be impacted and I dont have other AP's but I have LAN to each mini box so at least I can connect them up - again unsure if that will work or if the Sky mesh needs to be in place.
