OK, so I've replaced the ARC in my USR-TC chassis. Make a difference? Of course not. ... some of my users, can get online, a monitor ppp shows me incoming and outgoing data, but a simple ping of their IP returns "TIMED OUT" The users that it's happening to *IS* consistent.. it's the same few people every time.. regardless of which card/line/modem they come in on. If they dial my other USR chassis in another location, (with the exact same config on it may I add), no problems at all. Is it possible to pull the system firmware FROM the flash so that I can make my two systems identical? If not, does anyone have version 4.1.59 available? (Old, I know, but it bloody well WORKS). Thanks in advance for any assistance. Regards, Justin Wheeler -- Computer programmer (n): Red-eyed mammal capable of communicating with electronics and inanimate equipment.
