Home Networking / Router / & WiFi Gateway Help

[kerryjeanne]

So my internet connection starts getting erratic and I am told, by at least one person I call, that it is because I have an "old modem." And that I must take it in and get it replaced. (Comcast's equipment become obsolete. Shouldn't they be responsible for replacing it, for the $134/month I am paying them?). So I stand in line for 45 minutes, get a new modem plus directions for getting it up and running (though today I must bring back the old one, even tho it is obsolete. . .?), and despite following to a T all their detailed instructions, I lose all internet connection. Then I spend an hour on the phone this morning with a young man and eventually get connected on my laptop, but not on the desktop. He gives up, sends me over to some other technical dude, who tells me I must PAY for the technical support to get my desktop online. I am speechless. Thankfully we now have a FIOS option here.

You can get help on these forums if you post more info.

Why didnt your bring the old one with you when you picked up the new one ? When you do return MAKE sure you get a returned equipment reciept to prove you returned it. Comcast has been known to charge customers for devices they have returned because Comcast has no record of it being returned.

I didn't know how complicated it would be to hook up the new one. . .and I did  not want to risk being without any internet at all. And, I'm thinking, if it is old and obsolete, what do they care if I return it or not?  sigh.

Well, maybe. But if a Comcast rep. can't solve the problem in an hour+ on the phone, what are the odds I can get it resolved via a discussion board? Plus (have others found this?), each time I call I get a different response. Sometimes they want numbers off the back of the modem, sometimes they don't even ask me for that. Sometimes the problem seems to be this, sometimes it's that. . ..  So I will call again. Maybe I'll get someone who actually knows how to help.

We dont work for Comcast. If you need your modem provisioned its best to call them.

[kerryjeanne]

I understand that. I am venting ;-).

Refer to my original post below:

As dated, I am still without my setup as it was prior to "upgrading" to the triple play option. I have called CC several times, but they continue to provide weak or zero support. 

I have followed the instructions as described, switched the modem service to a 'bridge', etc., replaced my wireless router, etc. 

I am now forced to sign up for the CC premium site service as my problem still exists, and every avenue explored has come up empty.

I hate comcast.

Pulling my hair out trying to set up my home network.ANY HELP WOULD BE APPRECIATED!!!!!

My previous set up was with an older Comcast Motorola modem cabeled to a 4-port wireless router (Linksys WRT54G2). From the router, I tethered an 8-port Linksys 10/100 switch. To the switch I connected my Canon ImageClass MF4270, a file server, and (2) desktops. Worked flawlessly! File sharing, network printing, everything! Even wireless connections worked for handhelds, and my G/F could print across the wireless network.

Upgraded to the ARRIS TG862GCT by Comcast b/c of the new pricing (Feb '12) This is an AIO device as you know, phone, internet, 4-port hub/switch. I noted that this new hardware has a different IP structure; my old IP addys were 192.168.XXX.XXX. now, this thing has an odd address structure, something like 107.X.X.X.

Now, I have NO wireless printing, NO wired printing/networking, NO connection thru the switch. Upgraded the switch to a Netgear 8-port gigabit switch, STILL nothing. Had (3) techs out to troubleshoot; modem has been replaced a THIRD time. Tech's could not get network corrected, claimed NEW switch was BAD.

Tested the switch, pass. Changed the printer IP address, nada.

I only have internet connectivity if I hardwire to the back of the modem. G/F laptop connects to the modem wirelessly.

All machines are running Win XP Pro, 10/100 networking or wireless.

HELP?

I had the same problem and tried everything for weeks. Nothing worked until on a whim I decided to update the driver for my printer. It printed immediately after that and hasn't given me a problem since.

After (6) months of messing with cabling and hardware, and getting Comcast to send someone competent to my apartment, my network is working 100% (YAAAAA!)

I had to replace my old Cisco 4-port wireless router with a new Netgear unit, and my old 8-port switch to a Netgear pro Gigabit switch.

I have access to BOTH the Comcast wireless network, and my Netgear wireless network, but I am connecting to the Netgear to allow for file and print sharing.

The Tech that came out was very sharp, he actually had IT/network experience, so he was able to troubleshoot things very quickly. He suggested that I COULD take my old router and do a flash upgrade to the firmware, and that would most likely make it functional with the ARRIS modem.

Bottom line is, I dropped about $500.00 for the new hardware, and it works the way I want it to.
