Buffering and slow loading on MacBook Air

[Mitch63]

I have Sky 300 Broadband package.  Usually good enough for TV and two  laptops.  But recently there is slowness on the Macbook Air and buffering - all times of day.  Never had this before even with reduced speed Broadband.  Tests find download speeds as expected.  And I do not have this issue on TV and other work laptop.   Any suggestions?  Could it be a laptop issue?  Or is it that the network has become busier?  Or something else?

The fact that it's just the one laptop points the finger firmly at itself most probably. Is it also a work laptop? Is a VPN in use? Is the other laptop also a Macbook Air?

300Mbps is more than adequate for that use by the way, download speeds don't affect internal wifi speeds.

Try disabling Sky Shield & iCloud relay.

Thanks. Yes it is unusual that only one device.  The Macbook Air not a work laptop.  Other one is a work.  Not aware of a VPN but will check this out
