We're on what they named 'Sub-fibre', fastest interntet available to us. This is using a BT HomeHub3. Please see the screenshot below (with awesome snipping tool writing).
The connection over wireless is consistent (however there is an issue with this too; it will be 2-4ms while inactive but when gaming it tends to also intermittently rise to 500-900ms for seconds at a time), but as you can see on the right I'm dropping packets and then going straight back to normal. This doesn't seem to have a pattern to it, but it happens very often. It is strange because only one packet load at a time is affected, and the speed is always fine when they are delivered.
The HomeHub is connected to a BT OpenReach router plugged into the wall fixture. There is other WiFi in the area but it is uncontested on Channel 6 other than the BTWifi which I don't seem to be able to opt out of....
TL:DR - I'm getting dropped big packet loss out to the internet, and when I game my router slows right down.
I apologise not coming pre-prepared with cabled screenshots but NO ONE MAKES LAPTOPS WITH ETHERNET SLOTS ANY MORE!
For about £3 you can get a usb to ethernet adapter from a well known auction site.
We are a business and having the same problem on Infinity Fibre. All of Google's servers are dropping packets every so often. I contacted BT who are blaming Google.
I asked the BT adviser to try a CMD>PING google.com and he said he gets dropped packets too.
Surely someone at BT has a direct line (being a major ISP) to someone at Google to resolve this!!!
FYI: This has been going on for a few days now.
