I have a D-Link DIR-825 router and for some reason it is blocking one of the wired desktop computers from accessing Internet, while it still allows it to communicate with other computers in the LAN. And also, those other computers can access Internet without any problems. What's going on here?
I tried flashing the DIR-825 with the same firmware version 2.01EU. And then I load my settings from file. And it's the same thing again. I also tried with 2.06EU which is some mystical firmware version that is not published on any of the official D-Link websites but is available from the router interface when you check for new software. But this one didn't help either.
Also, one very strange thing is that this stupid box seems to remember the settings, even after you flash it with a new firmware. After flashing it gives the IP 192.168.0.104 to the desktop computer. This is the IP I had reserved for this computer. But this is before I even have restored my settings. So it appears to remember the old settings even after a flash process and even without loading old settings from file. Why is that?
Also, what file or files do I need to flash it with the DD-WRT router firmware?
