First off, the information..... at home I have Roadrunner high speed online with telephone service thru the same modem (Arris provided by Brighthouse) connected to a Linksys Wireless G 2.4ghz router. My computer is physically connected to the router and my wife & son use the wireless connection (only allowed MAC addresses).
NOW for the issue...for the last 6-8 weeks I've noticed that from time to time my phone will be "out of service" no dial tone if you call it goes directly to voicemail. I also noticed some drop outs on the internet and I've frequently (2+ times a week) had to cycle my modem & router. I see the companies trucks working in the surrounding area a lot so I assume it's do to some network issue. Yesterday it was out all day so I called and the tech says there have been no network downtime in my area to speak of. He checked from his side and he can see my modem but it won't go online (at the time) so I'm supposed to get a visit this evening to fix whatever the problem may be........oh and just for laughs everythings working again since about noon.
Soooo here's the deal, where would you put your money on what the problem is? Personally I think it's a line issue and the signal is getting degraded somewhere nearby. Optionally, I guess the modem could be bad or maybe the router has a short or some issues. Both are surge protected as well as the phone line. Place your bets....
