Thus, I had to go into the interface of the router/modem and tell it to act only as a gateway. The only device that ever connects to that gateway is my linksys router, so the ISP should have no way of telling how many devices are actually connected to the router. At this point my best guess is that the OP has at least five, perhaps more devices connected to one crappy little residential router, and it is understandably not at all happy with the situation, so it is flaking out. Maybe it's time to start perhaps some resource limits on your connected devices via the router interface, or else tweak your Debian system to not overhwelem the darned thing by lowering the maximum number of simul requests, etc. /guessing Best, AM -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

In any case, router/modems usually have a feature called "clone mac address" exactly for this kind of situation, it clones the mac address of your hardware and shows that mac address to the peer on ISP's side. -- Please reply to this list only.

But, well, as I said earlier, I had never had any problems with my ISP before. Thus, except if they radically changed their policy... -- Merciadri Luca See http://www.student.montefiore.ulg.ac.be/~merciadri/ I use PGP.

AFAICR the manual (well, I never read manuals), it is said nowhere not to exploit `too much' the router! Your explanation might be the key to my problems, but what else can you buy if you need to connect >4 computers? If you want something a little bit `bigger' (hoping for `stronger' too), you need to buy some 20 or 40-port router, which is completely useless for me. -- Merciadri Luca See http://www.student.montefiore.ulg.ac.be/~merciadri/ I use PGP.
