When I use Iphone 4 personal hotspot on USB, it works for a short time and then times out.

When pinging my iphone directly at 172.20.10.1, while I'm surfing and it times out, the ping shows nothing but "request timed out" .. Sometimes it "comes back" and sometimes I have to reboot my phone or disconnect the USB.. It's always done this and only on USB, it's very frustrating.

I have packet sniffed also, using Wireshark. When the "timeouts" happen, there's no more data coming from the Iphone. My PC continually sends ARP requests as well and don't get responses.

Have searched google endlessly and have gotten no where. This has been going on for several months and I'm just getting a bit fed up now.
