I've been looking at this for hours now. Please help 
Scenario:
Have new 3G dongle which doesn't work with the router I have (it's a 3G router but not compatible with this dongle).
Thought I'd get by for now by plugging the dongle into my PC (both "always on"), and then reconfiguring the local network and the router so the router does nothing more than act as a "pass through" or access point.
- USB 3G Modem plugged into PC, PC connected to internet via 3G modem, works fine
- Above declares itself as "Remote NDIS based internet sharing Device 2" - that's set to shared (sharing tab - sharing enabled, "allow others to control..." disabled as it's "always on")
- Router reconfigured so it is 192.168.0.254 (otherwise it would clash with the PC)
- PC connected to router via ethernet, LAN connection has fixed IP 192.168.0.1 *
- Laptop connected to router via WiFi, laptop wireless connection has fixed IP 192.168.0.4, default gateway 192.168.0.1, DNS servers set (to known good ones)
-Router has DHCP disabled
- All masks set to 255.255.255.0
Laptop can ping PC. It cannot however get any further - no internet connection. Pinging an Internet IP on the laptop that I can ping fine on the PC:
"Request timed out" or "Reply from 192.168.0.4: Destination host unreachable" (randomly) NB .04 is the laptop itself
Not a DNS issue, nothing works, cannot ping an internet IP address, shows yellow ! icon - No internet connectivity
The problem isn't Windows Firewall. Nor is it a "state after changes" thing, have tried resetting all the connections.
The wireless card in the laptop works fine. Or at least it did on Monday when I last used it.
Tracert (internet IP) gets as far as PC then all the subsequent hops die.
Question: Why can't the laptop reach the Internet?
* For some reason when you enable ICS for the dongle connection the LAN IP sets itself to 192.168.137.1 which I then changed to 192.168.0.1
