Linksys trouble?
Dad acquired a linksys 16 port 10/100baseT switch apparently forgetting that we had agreed on a ban on linksys products because they caused network problems and were poorly constructed. Said switch replaced my cisco 2900 switch which had the irritating habit of sending broadcast packets twice every second. Since the linksys switch has been the "backbone" switch our internet access has been dying 2-3 times each day and a traceroute shows that it is dying at the first hop outside our network which makes no sense, perhaps mediacom is suddenly flakey but the timing makes me suspect the new switch.
