| [cable] WAP problem
I have a Comcast Arris TM603G cable modem connected to a Netgear Wireless Router set up as an access point i.e. new IP and DHCP off.
Using cable from the Netgear to my laptop works. My laptop uses the DHCP on the Arris and I have internet access.
However, when I try and use wireless, communication stops at the Netgear Access point. I am unable to ping the Arris but can access the Netgear. I have tried manually entering the wireless IP settings (Arris) and it then claims to be connected but I cannot ping the Arris or connect to the internet.
I have searched for a solution to this but haven't found one. Any comments would be helpful.
Thanks |

You have to powercycle 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 Netgear Router needs to use DHCP on the WAN side. |

You need to turn DHCP on on the router. The modem will only hand off one IP, regardless of how many devices are connected. Unless you are being given multiple IP's by Comcast, which I doubt is happening, the Arris will not hand out multiple IP's. |

Thanks for the info. I had been trying to set up for Lan and Wifi depending on where I was using the comp which was probably doomed to failure with the IP problem.
However, I will try dedicated Wifi with DCHP enabled again. The last time I tried it the comp came up with an IP relating to the Netgear and couldn't connect to the Comcast even after re-setting it via the reset button. |

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.
Let us know what happens.

Do you have your modem plugged into the ethernet port on your computer and the wireless card connected to the router?
When you plug the router in after having your computer connected, reboot the modem. Let it come back on, then plug it into the WAN port on your router.

Just to clarify :-
1. With the Ipconfig I have shown I have :-
a) internet connection via modem-router-laptop on the Ethernet Lan.
b) no internet connection via wireless and I cannot ping the modem either
2. My router does not have a WAN port, just 4 LAN and ADSL phone port.
Thanks |

said by meditek8 :2. My router does not have a WAN port, just 4 LAN and ADSL phone port. Thanks There is your problem. This will not work on a cable system. With DHCP on your computer is battling with responses from Comcasts servers as well. Get a router designed for ethernet (with a wan port) and your problems will be solved.
Most likely that router / modem combo can't use the wifi with the built in switch to pass through the DHCP info, so it has to use the DHCP of the "router/modem", giving you no connection without being plugged in directly.

Yes, but I need the wifi to look at the Modem's DHCP in order to access the internet just as it does when on the cables. This has been the root of my problem all along. |

Thanks. That makes complete sense and is pretty much the conclusion I'd settled for. It must be the Comcast box because the setup worked fine back home with a different modem. :-( |

1 edit | The arris works just like a regular modem WRT DHCP. Something in your setup changed. It is just silly to use an ADSL modem/router combo on a cable network. Get a real router. You will be happier, able to use multiple devices, and be safer on the net.
BTW - when you reset the arris, just pulling the power does not do it. You have to take the battery out as well, or hit the reset button on the back of the modem.
