Hi, For one week now, I sometimes `loose' any access to the LAN and the WAN. Here is the way I am connected to the Internet:
ISP (house's wall) -> ISP modem (RJ-45) -> D-Link DIR-635 router (RJ-45) -> Switch (RJ-45) -> 192.168.0.101 (this computer). When trying to use my Internet connection, I sometimes encounter some load page error from Firefox. Checking the modem's LEDs, I notice that the RECEIVING and SENDING LEDs are then constantly lighted. Well, this is not normal. I then try to go to my router's webpage, i.e. 192.168.0.1 (this is my (LAN) DHCP server for 192.168.0.101 -> 192.168.0.111), and it does not load. I then reset the router, and everything then works right once the router has acquired the IP from my ISP's DHCP server. But if I switch off the router, say, for 10 mins, for example, the modem continues lightning its LEDs. But when the router is re-plugged, and an IP address is acquired from my ISP's DHCP server, the modem turns off the two respective LEDs, and everything is okay on the computers. First, I thought that I had some vulnerability (open port, etc.), which was responsible of the sending/receiving operations of my modem, but, as deactivating the router does not change anything to the modem state (it still keeps receiving and sending), it should not be a vulnerability. (Moreover, there is no reason to it.) I then thought that the modem was defective, but if it was the only defective device in my installation, why am I sometimes unable to access the router's webpage (and the Internet, accessorily)? And let the modem be defective. Then, the router should also be defective, but there is no reason to it, as it is brand new, both are on the UPS, and always worked fine. I can't understand this problem. Any idea? Thanks. -- Merciadri Luca See http://www.student.montefiore.ulg.ac.be/~merciadri/ I use PGP.
