Might be a NIC problem. Some older Intel NICs suck (although I do mean "older", aka EtherExpress 16). Might be a cable modem problem. Most cable modems now require "registration" with your broadband provider. Usually this is a one-time thing done at installation of your cable service, but occasionally the provider requires registering it a second time for various reasons. Usually they'll send you an email notifying you of this. However, it sometimes looks like spam so you don't read it <cough mumble>. The result is usually slower/inconsistent service. Also, make sure that your modem isn't placed near your monitor or other source of EMI. If it is, unplug it (remove power) and put it somewhere else. It's common with DSL and cable modems to have EMI problems that build up over time (sometimes they just stop working altogether, usually after a period of decreased performance) and the only fix is to power them off and on again. But if you don't move it, it'll happen repeatedly. Or, finally, it might be a software problem. But if it works intermittently, then I doubt it. -- Cliff Wells, Software Engineer Logiplex Corporation (www.logiplex.net) (503) 978-6726 x308 (800) 735-0555 x308 -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
