At the best of times wifi is a fickle beast that can be affected by numerous things such as distance from the Hub, building construction, other electronic devices, neighbouring WiFi, basically allsorts.
VM supply to the Hub, after the Hub it is up to you.
still getting packet loss, download speed looking good and so is upload but still freezing when watching streams on Computer and unable to live stream on twitch.tv when wired. badly need this fixing as I'm a semi pro gamer and rely on this for income.
I was told engineer was going to come out and upgrade from SH2 to SH3 but then day easrlier found out that its coming via YODEL and no engineer therefore could not do my downstream power levels...
Set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the Hub, it will take a few hours to get any kind of trend showing.
Your upstream power levels are all at the top of the maximum level in the recommended range and could be causing your issues. Someone else should comment on this soon but I reckon you will need a tech visit to rectify them
