For the past month or so, I've started to frequently experience the Internet connection temporarily dropping out on the cable modem (i.e., green lights start blinking) and, of course, also then causing a blinking blue light (modem connection) to appear on the wireless router. This problem very rarely, if ever, happened in the past.
When this happens, the modem (and router) just keeps trying to re-connect to the Internet and oftentimes will reset by itself and all be fine again within 15 – 30 minutes. Then, hours or even days will go by and everything remains fine...... until it happens again. It's really frustrating. If I'm annoyed or in immediate need of Internet access, I'll disconnect power from both the modem and the router for 10 seconds and then turn both back on again. That oftentimes but not always clears the problem. Things then might (or might not) remain fine for up to several days.
One more point -- Once in awhile (but not often), the problem includes this symptom: A Windows info box labeled “Network Error” appears on my computer screen stating “Windows has detected an IP address conflict. Another computer on this network has the same IP address as this computer. Contact your network administrator for help resolving this issue. More details are available in Windows System event log.”
It's getting really tiresome encountering these now almost daily intermittent “drops” by the modem (and router). What can I do to permanently diagnose and resolve this problem? What might be causing it?
Thanks for any help!
