Hi

I have tried everything to repair my RCA DCM245 modem because the internet connectivety is gone. From resetting, to having time warner reset the modem remotely and unplugging everything along with other ideas.

Time Warner will be sending a tech, but this has happened before out of the blue.

Only the PC Link and Internet lights are flashing.

Any help so I can fix this on my own would be very appreciated.

Thanks

J

It sounds like you've done the normal power cycle, reset, and re-provisioning steps, so I'll focus on some less common issues.

Check to see if they have put filters on the cable line.  Your service line should be tagged as having a cable modem inside. If not, they may have done a sweep in your area and added filters to block TV channels you're not supposed to get.  These can reduce (or block) the signal bands required by your modem.  It shouldn't happen, but it does.  The other is the line splitter coming in.  If it's flakey, it can reduce your signal strength.

One last possibility.  Has it recently rained (hard)?  Moisture in a compromised connector or cable outside can also kill your signal strength.  Until it dries up (which can take some time if it's condensation inside a connector) the signal can be pretty significantly impacted.

One other possibility from here

Is it possible you've got the standby switch pressed in? The article mentions

"When this modem is in stand-by mode, the Internet/Power light will be off. All other lights will operate normally. While in stand-by mode, the customer may still be able to release/renew an IP address without any problems. Please keep this in mind when troubleshooting PC connectivity issues."
