Hello,
I have heard a lot of reports from triple play customers saying either their internet is cutting out, phone or TV all the time. This could be due to bad hardware, bad cable splitters, but is most likely, saturated bandwidth. You will have to call comcast and have them troubleshoot the issue. Your IP phone modem may need to be given a less aggressive QoS setting etc.

Hi.

Are you saying your password with your wireless router? If you don't remember it anymore, just reset your modem and it will go back to factory settings, without a password. Somewhere on the router is a small hole. Unfold a paper clip and push down the button in the small hole for about 5 secs or until the lights go off and on again.

Thank you!

that is a wireless issue, the Arris is working because you are able to surf wired. Check you wireless router and make sure your setting are good on it. Otherwise, replace the router.

call comcast to activate your modem.
US amber indicates 100Mbps connection.

The NAT usually has to do with a device connected to a router. You cannot change the NAT on a modem, only a router. To change it to open, you have to simple forward portsneed to contact ur internet service provider for port forwarding.

don't need, just go to http://192.168.2.1

and if you can't access with the default password (think is admin :)

press the reset button of the cable modem just for router only, in case you have also telephony integrated.

go again to the address above and configure your password and router to whatever you like

hope this helps!!!

Hi,

Thanks for writing to Fixya.com.

You have to power cycle the Arris by using the reset button on the rear of it whenever you change the device that you are connecting directly to it. The Router you are using needs to use DHCP on the WAN side. To be more specific try like this. Reset the router back to factory settings. Unplug it. Reset modem. Let modem lock completely. Plug in router. Plug your computer into the router via Ethernet. Set up your wireless network.

Thanks for contacting Fixya and please accept the solution if it has helped you.

If your router does not have the default password on the back/bottom (usually located on a serial sticker), then the next easiest thing to do is, assuming that you have a patch/straight-through rj45(ethernet) cable, like one that you may have used to connect your modem to your computer, and plug one end into your NIC card, and the other into an ethernet port on your router. After you do this, use your computer's internet browser to get on the router's configuration page. To do this, go to your address bar and type in your router's IP Address, which, if using a linksys, is 192.168.1.1 by default (another way to find it is to go to command prompt on your computer, and type in the command "ipconfig" and looking at the default gateway). After entering the router's IP address, a window should pop up asking for a username and password, which, once again by default, are "admin", "admin", or "admin", "password". This should bring you to the configuration page for the router. From here, look for wireless security, and under that header, you should find your WPA settings and passkey. Change it to your liking, and when finished MAKE SURE TO CLICK SAVE SETTINGS AT THE BOTTOM OF THE PAGE OR THEY WILL NOT SAVE!!!

It maybe a pin hole sized hole,using a cocktail stick or a ball point pen and press and hold for 10 seconds should reset the modem.
Hope this helps.
