Hi John, Hi Charles It's impossible that the Hardware is causing this problems (except the NIC). The cables are STP cables (shielded) and from a famous swiss cable manufacturer (not cheap). Anyway, we had another NIC in the box and with that one, we had no problems. Now, you may ask "Why do this guy not use the other NIC which works?". Let's tell you the story about this box:
1. Friend got cable, I configured him a box with to old NIC's (this SMC and the DEC) 2. Friend uses his cable first without an LPR box. ISP uses MAC address database to limit clients behind cablemodem (depending on type of subscription, you may conenct 2 or 4 clients directly to the cable modem). My friend has the smaller subscription and may connect 2 clients (which also means two public IP's) 3. ISP MAC address database is bullshit because sometimes, database thinks that a customer already have 2 or 4 clients connected and the DHCP don't give out any leases. (You don't get an IP if you connect more than 2 or 4 PC's). MAC addresses which are not active anymore are deleted from the database after 24h of inactivity. 4. I go to my friend and install the box. I notice the same strange thing as I described already. My first idea: NIC is damaged. I install a new NIC (a new and expensive Intel PRO 10/100 PCI) and THE SAME AGAIN. we get a lease but the connection is VERY slow. We try to connect his PC directly to the modem again but then, we don't get a lease. We now think that perhaps the database was causing the problems with the first NIC because with the new NIC, things don't work either. We think that the database thought we already have 2 clients before we started to install the LRP box. 5. After 24hours, the new Intel NIC get's an IP regularly fast (yesterday, the we got a lease just some seconds before DHCLIENT stops trying) and everything is working fast. 6. We now (think that we) are sure the database was causing all of our problems and plan to change the NIC's again to the old one (I want my expensive Intel back :)) 7. We change the NIC's again, same problem. We wait 24 hours 8. STILL the SAME. Now I'm confused. Where is the problem? ISP? NIC? both? I hate problems where you can't definitely say what's the reason for it because you don't know everything (My ISP would know it, but you don't get any useful information from our ISP) I now think that we should trash this NIC and install a new one. What do you think? other ideas? greetings Sandro Minola > -----Ursprungliche Nachricht----- > Von: Johdomi [mailto:[EMAIL PROTECTED]] > Gesendet: Freitag, 28.
