Work laptop issue with Sky router

[Richard+Burgess]

Work laptop - been working fine for the past 2 years with same sky hub on a wired and sometimes wireless connection. 
For some reason now, when connected to the sky router, I cannot access regular websites e.g. bbc.co.uk, cannot access the work VPN, IT support cannot dial in remotely.  Teams, Outlook all work fine, so it's blocking some types of traffic, but not all. 
When I connect to a hotspot on a phone, or in a public wifi, everything works fine, so it is a problem with the sky router.

I have done a full factory reset of the router, the broadband shield guide is OFF, so all traffic is allowed. 
My IT support have tried everything they can think of, including all firmware and software updates, but as it all works fine when in a cafe or tethered to a phone, there's not much more they can do. 

UPnp is enabled.
I can access all the sites I need to on other laptops, or phones, connected wirelessly or wired, so they're not being blocked globally.

Any suggestions!?

I have the same issue! Please can someone from sky support?

The issue that was causing this was another WiFi access point (not a sky one) connected in my house. This was causing IP conflicts with just my work laptop. When I turned off the other accesss point the problem went away. 
was very frustrating though as some things worked and others didn't

That's interesting, how did you figure that out? 
I don't have another access point in my house but can connect to neighbours

I turned off every single item in the whole house that connected to the internet and then turned them back on one by one, and that's how I found it.
