Changed my router, why would Sky Go stop working?

I note that model is one advertised as coming with 'Air Protection Pro' 

Is this something you've investigated?

AI Protection Pro is about protecting the LAN from malicious activity on the WAN. I don't think it's relevant. Is was ON but switching it OFF has not cured the issue.

It has to be a setting on your router or some oddity in your setup because I run a AX88u and can access my Sky Q recordings fine via the app

@DRY411S  have you performed a network reset on your sky Q tv box's after installing the asus?

That would be your next step...

I've identified the cause of the issue.

The router installation wizard did not use the DHCP option 61 with user@skydsl|password to configure the WAN.

Instead, it enabled 802.1Q , set VLAN ID to 101, the 802.1P setting to 0, and put a 6 digit code in DHCP option 61.

The managed switch in my picture in the 2nd post above is old. It does not support 802.1Q protocol.

If I plug the Sky Q box directly into the router, bypassing the switch, I can access the recordings.

Time to buy a new switch I guess, since I have failed several times to manually set the user@skydsl|password option that others have suceeded with.

Thank you @TimmyBGood@jamesn123 @TomThumb5ive for all your suggestions. They helped me focus in on the root cause. It is strange though that with the router provided by Sky (ER115), it was all working perfectly.

Just to confirm that replacing the old switch with one that supports 802.1Q protocol, has cured this iissue.

For the record I bought a TP-Link TL-SG105E 5-Port Gigabit Easy Smart Switch
