Networking Question
-
I am playing with a networking setup on a Windows XP computer. It is setup like this: 1. The computer has an Ethernet NIC (PCI) with RJ45 (100Mbps) port. 2. The computer also has a USB modem from VirginMobile plugged in to get access through the 3G network to the Internet. (This part works fine.) 3. From Control Panel | Network Connections, I use the properties of the connection for the VirginMobile to set it to "Allow other network users to connect through this computer's Internet connection." The Home networking connection is set to the Ethernet NIC. (This is done from the "Advanced" tab.) 4. I connected the Ethernet NIC to a Wifi router's WAN port using an Ethernet cable. The Wifi router had been setup to work properly. 5. I fired up an Android tablet to connect to the hotspot offered by the Wifi router. The connection was nice and strong. After all these, I expect to be able to get access to the web from the Android tablet. It did not work. To try to find what the problem was, I connected a laptop computer to the Wifi router using a physical connection (Ethernet cable). The computer also connected to the router with no problem. DHCP worked fine and it obtained the IP addresses. But Internet is not available. Somehow the above shared network did not work. On the XP computer, the command ipconfig/all showed correctly assigned IP addresses (I believe.) By the way, a different setup worked briefly, but quit working after a few days. The setting is like this: On the XP machine another PCI card (Wireless G) was installed. This card was setup to be in "AP" mode, and again the VirginMobile USB modem connection was set to be sharing Internet connection. The Android tablet could connect to the AP and then go to the Internet. However, after a few days, the tablet could not connect to the AP any more. It got stuck at the point saying "Obtaining IP addresses..." What was wrong with my setups? Anybody had done similar things?

Wow, your setup is a bit of a cluster f***... I'm having a hard time understanding where this is breaking down since you have so many steps. To try to break down where you don't have internet access, try a few things: 0. Check to make sure you have an IP address. 1. Make sure your gateway is configured properly (will depend on your configuration). 2. Make sure you have name-resolution. Usually you can use ipconfig/ping/tracert to figure out where your connection breaks down. If you don't have name resolution, you may have to explicitly state who your name server is.

From your Android > disconnect and reconnect it to the hotspot. This is quite the cluster whooey... So you can access the internet from everything but the tablet? Go into device manager and make sure the Wireless NIC properties are not set to power off. Set it to CAM if possible, which is constant awake mode. Check the power settings in control panel as well, as some power plans will kill power. Have you tried restarting everything? Another thing to try is IPCONFIG /RELEASE & IPCONFIG /RENEW on your XP machine to renew it's IP address.
Something worth reading, albeit it's invincible!

Sounds like you are running two DHCP servers on the same segment. When you switched on ICS on the XP machine, you effectively created a DHCP server. The WiFi hotspot probably has its own DHCP server. The Android X| tablet is trying to get an IP address. It gets it from the WiFi router. For it to work with the ICS it has to get an IP from the ICS DHCP server, not the WiFi hotspot, otherwise the traffic from the tablet will never reach the ICS NAT gateway (different IP class and subnets). Lots of options to get it working but simplest would probably be to "steal" an IP from the ICS server and set the tablet to use a static IP set to the stolen one and having a default gateway of the ICS server (XP box). The DNS would also have to be set to the ICS server.
