Extend Arris G862G Modem with Airport Extreme

The "wizard" will provide you with the correct setup.....which is not extend the network. Extend the network is used only if the AirPort Extreme is connecting to another Apple router using a wireless connection. You are using Ethernet. It is possible that the prior instructions from LaPastenague confused you.

Please follow these instructions carefully in the order in which they appear:

Make sure that the Ethernet cable connects from a LAN <--> Ethernet port on the Arris modem/router to the WAN "O" port on the AirPort Extreme.

Power up the AirPort Extreme if it is not already on and let it run a minute or two.

Hold in the reset button on the back of the AirPort Extreme (it is located just to the right of the power socket) for 7-8 seconds, then release the button and allow a full minute for the AirPort Extreme to restart to a slow, blinking amber light status.

Click the WiFi menu at the top of the Mac's screen and a screen similar to the illustration below will appear

Click directly on AirPort Extreme

That will get the setup wizard up and running. It will take a few seconds to display a screen that is similar to the illustration below, except that you will see a picture of the AriPort Extreme.

Note that the AirPort Extreme will be configured to "create a network". This is the correct setting when the AirPort connects to another device using an Ethernet cable connection.

Network Name.......Type in the exact same wireless network name that the Arris is using

Base Station Name.....Type in a name that you want to call the AirPort Extreme. AirPort Extreme is an example

Password.....Type in the exact wireless password that the Arris is using

Verify......Type in the same password again to confirm

Click Next

The wizard will set up everything for you automatically. When you see the message of Setup Complete, click Done. And now you are done.

The Ethernet cable from the Arris to the AirPort must remain permanently connected at all times, as I previously noted.

No sorry.. apple designed their products to work only with another Apple router.. It cannot extend universally.

You can use ethernet .. a much better way to go btw.. to connect floors and then setup the Extreme as Wireless Access Point.. WAP. Or you can use EOP powerline adapters.. but they do not always work and will never work as well as ethernet.

Note I have just replaced an Apple to Apple wireless link because it actually failed to work properly doing VOIP or SKYPE or WhatsApp calls. In the end two way time sensitive links .. not just streaming in one direction or pure data.. simply is not great.

To avoid confusion, I am not going to post another set of instructions at this time. Try things out. If you are still having problems, post back and we'll try a different approach.

I'm not sure if you are clear on this, but if you need more wireless coverage upstairs.....for best results, the AirPort Extreme will need to be located upstairs in that area......AND....the AirPort Extreme must connect back your Arris modem/router using a permanent, wired Ethernet cable connection.

Ethernet over Powerline (EoP) adapters were mentioned as a possibility if you cannot run the cable, but good performance with these devices cannot be guaranteed, since there are always a number of variables in any home that will affect the results.

Reset the extreme to factory settings.

Then run through the airport utility.. setup wizard should get it right.. and keep hoping like crazy it works.. automagically.

You will know it worked properly if it shows that it has configured to extend over wire..

No issue if it fails.. as it usually does for me.. perhaps I am just unlucky then you can do it manually.. and it is easy with the proviso you have ethernet on your computer.. or a thunderbolt to ethernet adapter.

Bob will usually give you the details of how to extend by wire automagically and he is a lot more LUCKY than I am.

Re: TC Extended Network

If it needs manual setup simply start from factory configuration and set to bridge mode with create a wireless network.. I can give you the screenshots if needed.. hope and pray for successful automatic.
