I moved from Crawley to Sawbridgeworth on the weekend, to an area where Sky dishes are not allowed (and subsequently a lot of people go for a Virginmedia bundle). My very under-utilised Crawley connection has now been exchanged for something much different. I can see arround 8 virginmedia SSIDs nearby, previously I could see none!).
The increase in minimum latency seems to be partly due to me streaming via Lovefilm (the outage was when I was rearranging everything).
Despite taking my V1 Superhub and TiVo with me, I was given a Superhub 2 and a new Samsung Tivo. I'm currently using the SH2 in router mode, mainly for the 5GHz feature.
Strange thing is, despite having a dodgy -looking graph, everything seems to be working fine.
