Everything was working all right just before I went internetless because of my ISP for about a year. Basically, my configuration is set as follows: 2 computers (a PC and a laptop) always connected to a 8-port switch, which is connected to an ADSL modem (through the LAN port on it). I meant all right because I was able to get internet to both computers through the switch connected to the ADSL modem by the ethernet cable.
ISP -> ADSL modem -> Switch -> 2 computers
The problem began once my internet connection was reinstated, which happened like 4-5 months ago. Now my laptop is the only one who detects the ethernet cable (and gets connected to internet) when it is plugged in directly into the ADSL modem since the switch no longer recognises it. The switch, like every other switch out there, lights up a LED to indicate that a certain device is attached and successfully connected to it; mine works normally when you attach any computer into it (I'm even able to set up a local network by attaching multiple computers to the switch to transfer file amongst computers); however, once you plug in the ethernet cable from the ADSL modem, it doesn't work, the LED where the ethernet cable is plugged in keeps blinking like every 20 seconds and after a few minutes it just lights off, so I'm not getting internet to the rest of the computers attached to the switch any more. Even attaching another computer directly into the modem (except the laptop, as I said earlier) won't work either. The ethernet cable doesn't get detected by the operating system (I've tried both Windows and Linux-based OSs, and it just the same).
I simply don't have any clue as to what could be happening here, may it be the ADSL modem, which is kind of old since I've been using for 5-7 years straight without any firmware update? I've reset the ADSL modem many times from both the web interface and the physical small button next to the ADSL port.
Do you have any ideas what is going on here?
