I have a bit of a weird one. I usually use Chrome as a browser - but sometimes I get an error message of "network unavailable" - hitting the refresh generally works to clear this. As does firing up Firefox.  I do use the Internet to do thinks like stream music and use timers - and these momentary so called losses of connectivity - can put these applications into a bit of a loop. 

The issue seems to  be gradually getting worse (we moved  to the property just before Xmas). I suspect its to do with the amount of competiting traffic on the line (we are at the end of the street) 

I'm wondering if it might be time to upgrade to Fibre (which is now in the street - it wasn't quite available when we moved in Dec). 

I've been surprised to find that he speed we've been getting with VDSL seemed as usable as the Fibre we previously had in a different property. Indeed I found that streaming lightbox is BETTER on VDSL (how does that work?) 

Just did a speed test https://www.speedtest.net/my-result/4253462924 

Any insights on this? The upgrade would be free - it's just a matter of the disruption while they install.
