Using Ethernet is unlikely to help I'm afraid to say. This ping and packet loss issue is apparent on WiFi and Ethernet for many other BT users. You could easy prove or disprove this by using a 1 mn Ethernet cable and laptop connected straight to your modem/router.
What do you mean a 1 "mn" and laptop. I don't understand. Could you add a little more detail please.
Yeah, instead of waiting on electrician to then find out using Ethernet does not resolve ping spikes and related issues just try a test with suitable device and short Ethernet cable,
Sorry for the typo - I meant "1m"
If a laptop directly plugged into the Hub gets no packetloss shouldn't I get no packetloss if I just run a ethernet cable down from my room to the hub and get max peformance of my wifi 300 mbps instead of 150 and get no packetloss at all.
Personally I would sue a Ping Plotter screenshot to show as much information as possible. Run a ipv4:www.google.co.uk ping via ping plotter when connected via the WiFi Disc, and one when connected directly to the HUB via Ethernet.
PingPlotter will show you the ping at each hop of a trace route (which also gives us more information as to which servers your routed through in BT's network) we can try and use it to determine if it's an issue when connecting via WiFi or if the Issue persists when Hard Wired.
Did it through pingplotter google.com and this is the results just count top is number 1 etc.
You need to screenshot the whole thing for us to see the hops, dont worry no personal IP's or anything will be shown.
