I'm currently stuck with connecting to the internet by USB tethering an android phone. It works OK, but it used to work better.
It used to connect almost instantly as soon as I set the the thether from the phone, but nowadays it takes forever to get there: 1:30 to 2:00.
I suspect it may have something to do with the fact that almost each time I connect again, a new network popup window appears for me to choose what kind of network it is, with an increasing number: I'm on "Network 139" now.
Could it be that Windows7 is keeping track of the differences (private IP assigned by the phone, I guess?) each time it connects so that it can compare and find out if it is in a known one again, and this process is what's increasing the time it takes to finally giving me service?

Regardless of this hunch of mine being right, can I just clear all the "old networks" and prevent it from caching them again? It's really the same connection after all...
