Hey,
To begin with, I'm on BT in the UK, and we're on Infinity(1) which is copper broadband usually fetching around 16/2mbps. Recently however (for the past 2 days) the connection has been particularly shaky, especially when there is many devices on the network. It's 11:20pm here at the moment, and I'm currently fetching around 374ms (lowest) to well +1000ms through 4.4.2.2 with frequent timeouts and similar to 8.8.8.8, which I can remember as having a baseline of 28ms usually.
I'm wondering why this is. My sister recently purchased a laptop which I thought was the reason why, as for some reason Office 365 was using 1.5mbps of our upload bandwidth whilst installing last night, and I assumed that was the reason why the internet was in this state. But it's carrying on today, and I installed it earlier today. I even went to the extent of turning it off via BT Access Control (for some reason mac blocking isn't allowed in Home Hubs) and the ping didn't differ. The only time when the ping did differ is when I turned off the WiFi transmitters altogether, which returned it to the 28ms baseline.
It's confusing me as we don't have any particularly high priority devices in the house. All there is, is my sister and mum's phones (4s and 5s), a 1st Gen Chromecast, my sister's PC (a Lenovo with "high speed" internet), my OnePlus X running CyanogenMod and my personal computer, which is running through a length of Cat5e.
I was also watching a twitch stream earlier, at source (which draws about 5mbps) with my sister and mother out, and so there being basically no activity on the network. It buffered which is odd, as the 16mbps connection we have should be plenty enough to stream twitch, and I have done so comfortably before these two days.
Also, if this is anything of note, a device earlier with a foreign mac address connected to our 2.4GhZ transmitter, with an "unknown" tag with it, usually associated with android devices like my OPX or other uncommon networking devices. I quickly access blocked it permanently and it later left our WiFi, however that hasn't resolved our issue whatsoever.
I'm pinging again at the end of writing this, and the results I've got are this:

It's confusing me greatly, and I hope you guys can help. Thanks in advance.
