Re: Arris TM502G/CT Modem w/Comcast Cable Internet ...Battery?
said by rody_44  : i just assumed people knew that part of the equation. you would be surprised at the number of people who do not understand this.. thinking the modem battery will run their cordless phone..
if they had a phone that was powered by the phone line, then it would work during a power outage.. |

Don't talk about topics if you don't know about them. If your power goes out, your phone will still work, as long as the cable system hasn't lost power outside, which doesn't happen during many power outages. |

With this Arris POS, it seems like the only successful way for me to get it to stay online is to disable all Wireless encryption and just use MAC filtering with no encryption or the modem disconnects the router and just blinks yellow on "Modem" and never establishes solid blue on "Internet" (anybody who has this series knows what i mean). Literally, the only way to get it to connect again is a hard reset back to defaults with no security and it magically connects... but it works...just with no encryption... The TM502G is a great modem. If your wireless works fine without encryption, but not with it, you've got another problem - because all you're changing there is how your computer is connecting to the wireless router, that change has nothing to do with how the router is connecting to the modem.
Of course, doing a factory reset should be doing other things as well.
But as far as the modem's concerned, it's just a device with a MAC address that's requesting an IP - whether you're hardwired to the router, or using a protected or unprotected wireless connection, it doesn't know and doesn't care.

nope no worky during blackout..the modem will ligth up but no dial tone.
we talking cdv.
The battery backup will keep the MTA itself connected to the network as long as there's an available cable connection to it. A cable outage is another story - as is a power outage that would cause a cable outage (there should be some methods in place to minimize that, but you can't prevent everything). If "the modem will ligth up", it sounds like that wasn't a power outage - when it's running on the battery, the power light will flash and the telephone light will be solid or flashing (solid if in service and on hook, flashing if in use or while attempting to complete DOCSIS or telephony registration/connection) but DS, US, online and link should be out completely... And, of course, if the battery was not working, not there or deleted, the lights would all be out. So it sounds like you're talking about something else. |

said by JCzerniawski :Since it has that battery backup, does pulling the power cord REALLY reset the modem or do I have to "take out the battery"? Just use the reset button on the back of the modem. If you pull the power cable it just puts it into standy mode and shuts off the internet service to conserve energy for the dial tone.
There is nothing wrong with both Arris models and using a protected wifi router. I've used both with two different routers running a secured network and never had a problem. In fact my current Arris is feeding two fully protected linksys without a problem.
To stay on topic... let us know what modem the tech brings out next time. Verizon is very busy around my area so maybe I can try out the 50meg plan soon. |

Let me tell you that I have this Arris TM502G/CT Triple Play garbage cable modem with a Belkin N1 Series 1xxx Wireless Router. I've lived in the Manayunk / Roxborough section of Phila for about 2+ years and with the Surfboard modem, once in a blue moon there was a problem where i had to power cycle everything to kick it back on...we're talking monthly maybe, otherwise, perfect.
With this Arris POS, it seems like the only successful way for me to get it to stay online is to disable all Wireless encryption and just use MAC filtering with no encryption or the modem disconnects the router and just blinks yellow on "Modem" and never establishes solid blue on "Internet" (anybody who has this series knows what i mean). Literally, the only way to get it to connect again is a hard reset back to defaults with no security and it magically connects. I seriously thought my wireless card and router (Both Belkin N equipment) were just cr@p but it works...just with no encryption...I guess I can live with MAC filtering...
Since it has that battery backup, does pulling the power cord REALLY reset the modem or do I have to "take out the battery"?
I'll save the "It took me over a month to get Comcast in my house" speech for another post, because they are a garbage provider in my eyes...too bad FioS wont make it down here anytime soon, although i heard they just started Philly up by Bucks county so heres hopin! |

Apparently you have no idea what your talking about. If your house loses power the whole point of the batter is to keep power to the modem so your phones will still have Dial Tone. (for 8-10 hrs) Keep in mind this doesnt apply to cordless phones cause they need power to turn on and work properly.
Now if the cable in your area has an outage than you will not have phone service. |

I have a simple question .. er, two questions.
1) can I find instructions somewhere on how to optimally install my D-link (802.11g 2.4 GHz) router to my just installed (courtesy of my forced migration from Insight to Comcast) Arris TC502G/CT cable modem?
2) Has anyone experienced a sever loss in speed as the result of installing a wireless router (in this case the D-Link described above) with a cable modem (Arris in this case as described above)? My speed before router install was 10-12, now it is 3.5-4.5.
Thanks for any help! |

fwiw, you can pull the battery if you want. that will accomplish what you want to do. your not going to pay any more rental for it. the modem rental is three dollars no matter what you have. as far as hold times, yea they are long for contractors and techs in the philadelphia region BUT the tech shouldnt have to call dispatch to swap a modem. its because techs dont want to follow protocall that results in the long hold times. techs have a whole slew of numbers to use and still just call dispatch to do it. they have tier2, ivr, and the walled garden number but they still insist on calling the one number. |

Mine came with the 10 hour battery.
Here, being in a Block 50 area(Fire Dept/Hospital)), any outages will get fixed rather fast!

Yay, thank you 
I went to the very cool Arris status page found on the site here and it does show that the Battery is missing in the Event Log and CM State.
The modem's working fine, just wanted to be sure Comcast wasn't gonna go "wait a minute, there's no battery in there" and shut me down 
Here's hoping the Netgear modem works out (once I can get the tech back out here).
MadMann, the Comcast tech did have a motorola surfboard (which is the one I wanted to have), but he couldn't get through to Comcast to get it set up. Something about it being refurbished and not "talking" to Comcast properly. He spent well over a half our on hold with Comcast trying to get that one working. Tell me there's something not wrong when a tech can't reach Comcast!
So, he had this one in with all his stuff, called a different number and got permission to use it instead. Now, if I find out they're charging me more a month rental? I will start hollering. |

Normally, they don't hand out the 502 without having CDV. Did they run out of their regular stand-alone modems? |
