I posted this to a similar post as this earlier. Dont know if it will help but it may be a good alternative to run your Nexus from.
Several years ago I purchased one of those thrustmaster wifi keys that are designed to plug into one of your PC's USB ports, so my PS3 could connect to the net. It creates a wifi hotspot. I was very pleased to discover that the nexus 7 connects to it also and gets pretty decent download speeds (depending on your carrier I suppose). It does make my PC download things alot slower when its pulling alot of bandwith but it never has caused anything thats connected to it to be booted.
Worth a shot I guess. Heck I paid like 20 dollars for mine and ive seen em cheaper online so its a pretty cheap fix Hope this helps!!!
