[Galaxy S I9000 General] Prankey:
I know this has been discussed multiple times and we ended the discussion by suggesting to use Mobile AP (WiFi Tether).

However, I defer from the above workaround which works great for me as well due to:

1. Using WiFi Tether unnecessarily increases the phone and battery temperature and can reduce the phone's life

2. I still end up connecting the phone through USB to keep it charging while consuming a lot of energy while doing WiFi Tether. If that is so, I would rather switch off Mobile AP and WiFi on my Laptop and use USB tether instead. Consumes much less power and reduces the network latency and could be faster than Mobile AP

3. Froyo builds usually allow upto 5 WiFi clients to be connected to the phone sharing the 3G connection (which is much better in my location than any other broadband format including ADSL!). Using USB tether on one workstation (like my desktop) I could share it on upto 7 devices (including phone and my desktop)

4. As an ambitious campaigner, I may want to use WiFi on my phone for one purpose, probably for using DLNA and 3G to tether internet connection on a PC! This may not be possible if I use Mobile AP as it will use the WiFi radio.

If this feature is "OFFICIALLY" provided by Samsung on their "released" builds, why is it so unstable??? I would rather like to get this working rather than we looking for a workaround like using Mobile AP which is best used when really needed.

I would like to use this phone sometimes 24x7 downloading huge stuffs and it will waste the phone if I only rely on Mobile AP keeping the phone HOT all the time.

I have observed the following while doing USB Tether:

a) Problem exist on all test and released 2.x firmwares including the latest Froyo JPK.

b) Indications are same when using "PC Internet" option which creates a "hidden" network connection with the PC when USB connected with the phone and "USB Tethering" box under "Tethering" option in "Settings" Page.

c) While the phone shows that it is tethering normally, somehow the PC "FREEZES" the "TCP/IP" Stack as pinging its own IP FREEZES the ping command. All the network monitoring applications also freeze during this time. This is a very strange behavior I observed during the initial days of Windows 9x when you had to restart the TCP/IP stack.

Infact this issue looks very unique as even in Windows 9x, I never saw the Network apps freezing like this. Resetting the connection fixes the problem and it cycles the same way after that.

I have tested this behavior on 3 workstations:

A] My Official Laptop running Windows XP SP3 with all recent updates and Norton Internet Security Corporate Edition (firewall gives access to the network)

B] My Home Laptop running Windows 7 Professional with latest updates and Kaspersky Internet Security 201x (recently updated 2010 to 2011 - firewall gives access to the network)

C] My Home Desktop dual booting Windows 7 Ultimate AND XP SP3 with latest updates and Kaspersky Internet Security 201x (recently updated 2010 to 2011 - firewall gives access to the network)

All the above workstations have the same issue pointing the issue to be on the phone hardware or software or USB cable (tried 3 MicroUSB cables including the official provided by Samsung).

I have been troubleshooting this issue in the last 3 months, could not identify other issue than seeing the workstation freezing the network activities quite strangely as suggested above. Any help by my fellow SGS users, developers, moderators will be highly appreciated.

Thanks for your participation, lets team up and contact Samsung to resolve this issue if it bothers many people like me.

EDIT: I would try to keep this post updated with usable comments/suggestions/workaround as we discuss
