Right, So I got my nexus around 2 weeks ago, I also purchased a TP Link wireless home plug to get wifi in my room since the walls are thick and I can't move the router. Everything was working fine after hours of tedious fiddling, then I went of for the weekend and took my nexus with me, Noticed I had a software update to 4.2.1. Which I did, on the bus journey. I came home today to find that I can no longer connect to my home plug.. Is this the software update? I mean there isn't anything else that's changed other than that. Any suggestions? Starting to get annoyed at the lack of internet in my room
