I did a system restore on my win 7 laptop, after which it could only establish a partial connection with my android device. I've tried to play around with the connection settings to no avail :/ . What am I going to do next?

Forget USB for a moment and with the Portable Network turned on in the Android device, does it not show up by name in the list of Windows visible wireless networks? System restore may have removed the saved settings for the device but it may have undone a USB driver update if you had it since the Restore Point date.

The computer recognizes AndroidHotspot4426 wifi access point and tries to connect to it but achieves only a partial connection (some data packets have been received but none sent).

What comes to USB, it does recognize the phone correctly, but can't form an internet connection through it.

I could understand the other way around - it might send packets in the hope of receiving them but cannot if the wrong security password is in use. Anyway, change the password in the 'phone's Portable Hotspot and enter the new one in the PC when prompted. If you don't know the phone's password, it doesn't matter. You set it and can just as easily change it for another.

You might also let the PC's firewall defences down for about ten nano-seconds for experimental purposes. Much longer than that and you could be at risk./

You are right, it is sending packets instead of receiving them (my bad). But the wifi password is correct, and it isn't an issue in USB tethering which doesn't need a password. I tried disabling my firewall also, but it didn't help. I'm totally at my wits end here :S.

I can't replicate this problem using my Android mobile phone so it's a mystery to me. I'll work on it and if no-one else has a better answer first, I'll get back to you.

EDIT - Whilst trying this the first time, I missed a big clue in the notification area. When I connected I see the message "blah blah Internet Connection sharing yada etc."and I wonder if you have that setting enabled. In the Properties of the connection, under the Advanced tab, tick the ICS box - I can't think why it should make a difference but it's my best shot at the moment.

I'm beaten I think but if this problem persists, download Engineer Mode from the Play Store and check to see if you can successfully ping Google. If that fails to come back, I'll ask one of the regulars from the Android Mobiles sub=-Forum to pop in here and take a look.
