First I found the following instructions on the web on how to set the device in bridge mode:
1. Access the modem interface by typing Http://192.168.0.1 into the browser, hit return and the modem interface with the user name and password entry input will appear on the screen. 2. The default user name is Admin and the default password is password in lower case. Enter password and the basic set up page appears. 3. Go to LAN setup and under Nat section select Bridged. 4. Go to the Firewall tab and unselect enabled Security will be provided by your own wireless router. 5. Under the wireless tab if the wireless is turned on uncheck enable wireless. 6. Install your own wireless router in accordance with the instructions that came with it.
I have not checked this out even though I did walk through the pages.
I sent an email to TWC and ask them to tell me if I had authority to use my own router by setting the Arris in bridge mode.
The next morning I received a telephone call from Tech support locally advising that the Arris has been set to bridge mode by remote control and I could install my own wireless.
I pointed out the inconsistency of the sales persons statement that they would not support on own personal wireless and I had to pay $ 5.00 per month or do without.
The tech advised that by saying TWC will not support your personal wireless means that if I have a personal wireless they are not going to tell me how to hook it up.
They will pace the Arris in bridge mode so you can hook up your own wireless according to the install instructions that come with the router.
I made the hook up and the Wi-Fi runs fine.
$ 5.00 per month is not much but why pay for Wi-Fi when you have a perfectly good wireless router just sitting there in the corner?
