An odd thing to happen. All of a sudden, the PC only managed a limited connection. The PC is connected to the wifi router via Cat5 cable, while a laptop connects wirelessly. All connections are assigned a dynamic IP by the router via DHCP. Router was connected to the internet, and the laptop received an IP and working connection. The PC, however, was assigned IP address 169.254.154.171 (could be a different last number; I can’t remember, but it’s not important), with subnet mask of 255.255.0.0 (this is why the exact IP isn’t important).
The IP address on the network connection on the PC showed that it could not obtain a valid IP address, so it was assigned that IP by Windows.
Restarting the router and PC didn’t do anything. Assigning an appropriate IP to the PC resulted in it showing it was fully connected, but it could not ping anything. Not even the router itself.
I thought it could be a faulty NIC, or maybe there was something wrong with the cable. Could not find any other advice to solve the problem, so it was decided to have the PC taken to a shop to be looked at.
Their advice? After some fiddling around (not sure what they did), they advised my dad that it had to be reformatted. So they backed up the files in My Documents (and only those files; no program settings or anything else) and reformatted the hard drive. *sigh* At least the PC can connect to the router now, and there was no need to replace the NIC or network cable. But couldn’t there have been a better solution?
