R6900v2 lost internet connection

[PICKLERICK84]

I lost internet connection (orange light) to my router (R6900v2) yesterday morning.  First few cable modem (CM1200) reboots would solve the connection issue, but only for a few minutes.  Called Comcast, the CSR advised me that my modems firmware was updated recently, and was unable to communicate properly with my router.  Upon investigation, I find my ISP controls the modem firmware, the firmware is up to date, but am not able to get the router to connect to internet.  Router is up to date, nothing has changed, that I know of, from Saturday eveing to Sunday am, besides time change.

1. What firmware is on the router?

2. Are you able to access the router's gui? Meaning can you log into it and make changes

3. Are your devices saying "connected, no internet"?

4. The cm1200 has 4x ethernet ports but comcast only allows you to connect 1 device to it. Try power it off, disconnect everything from it, then connect a pc/laptop to the port 1 and power it back on. SEe if its usable.If it is, then power it back off for 2 minutes and connect the router back to port 1 and power it back on. Then wait a couple minutes and power the router back on.

I will try this when I get home from work.

The firmware for the router is 1.2.0.88

Yes I am able to login to the router.  Status for internet says not connected.

I am able to get on the internet thru just the modem using my PC.

Again, make sure nothing else is connected to the cm1200 but the router. The isp only assigns 1 public ip address and if it assigns it to the computer and not the router, the reset of the devices won't work. 

If you had it connected, you'll need to use the disconnect/power off I outlined before.

I had the gf perform the reset procedure, but still no internet, orange internet light.

Try replacing the cable between the modem and the router. ensure you have a high quality cat 5e or cat 6 cable

[PICKLERICK84]

I will try, although the cable is new and is of higher quality.

Next step, I am thinking, will be to factory reset the router and/or modem.

I'm always a fan of a factory reset/reinstall. Sometimes fixes random problems.

I seen no suggestion that you tried the less drastic recover move, which is to restart everything in the right order:

It may help to reboot the whole network in the right order.

Be sure to restart your network in this sequence:

• Turn off and unplug modem.
• Turn off router and computers.
• Plug in and turn on modem. Wait 2 minutes for it to connect.
• Turn on the router and wait 2 minutes for it to connect.
• Turn on computers and rest of network.

If you didn't try that, it might be worth remembering for the next time this happens.

Please mark your thread as solved so others will know. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
