Report two annoying problems i'm having in General Discussion Posted October 2, 2006 Sounds like you almost answered that one yourself. Does it also do this when you bypass the router?? I haven't tried, nor know how, to bypass the router. If your cablemodem is flapping (and by your own description it is), check the coax back to the wall and remove any splitters/surge protectors that may be on the line. If the problem goes away then you need a new splitter, if not well....sorry you gonna need to call Cox. Your first and most important clue is that your cable light starts to flash which means your modem has cycled or flapped (flap=abnormal reinsertion to the network). This is not a router problem (guess thats good news) ...Good Luck! I'm probably about 85% certain there are no splitters or surge protectors on my cable line. Great. So I guess I have a fun call to Cox to look forward to.
