Have you tried resetting your cable modem?I have the same problem with @Home, except my activity light will stay on sometimes and powering it down and back on has worked for me.I have BlackIce and not getting any info, so it just might be activity on the loop.I spoke to ::....cough...cough:: tech support about it and they said we could try to replace it(the modem), but I would be with out service for 3-4 days because they have to reprogram the system. huh???😕
