Hot1 3 Com Cable Modem 49.95 after rebate(89.95) list 309

This modem is NOT compatible with AT&T Cable networks.

This modem is NOT compatible with AT&T Cable networks.

It's model 3CR29210, which is NOT on the approved list of cable modems.

It states on the box to setup as a 3CR29220 (which is on the AT&T approved list), but it will never get an IP to work. A friend tried and tried....no go. Ended up returning it.


Just a word of caution for you folks..... good luck
 
Jokersmoker:

I don't mean to crap on your thread, but this particular modem has been discontinued. Check out the following URL: http://www.3com.com/products/en_US/discontinued/cableqa.html. According to 3Com's site, they officially discontinued their line of cable modems after August 10, 2001. I remember reading about this last summer and had to jog my memory about why the 3com cable modem rang such a large bell in my head (more like a gong).

On the positive side, 3Com will honor all warranty's (5 yrs), at least that's what was written on the above URL site.

The only thing that I would be cautious about is if and when DOCSIS 1.1 replaces DOCSIS 1.0, will you be able to flash the BIOS on this cable modem?

Other than my concerns about the future upgradability of this modem, it seems to be a decent product at a kick-butt price. Maybe 3Com proves to be a super company and puts out an upgrade flash program. Maybe DOCSIS 1.1, when it arrives, will not represent a noticeable technological leap over DOCSIS 1.0. Or maybe someone will figure out that the 3Com's guts are the same as another manufacturer and we'll be able to use their firmware upgrade. It's so tempting........... except that I already have my own cable modem and don't need another one.

Jokersmoker, if you are thinking about taking my threadcrap personally, please consider that I would buy this modem (despite my above concerns) if I didn't already have one of my own. Thanks for posting. I will mention this to friends who are getting new cable hook-ups, and I'll mention my concerns, of course.
 
I got this modem with optimum online in august 2000. the modem stopped working during an electrical storm in june 2001, inexplicably. there was no obvious damage to the modem, it could establish a connection to optimum online, but no data would transfer. After about a month of difficulties, we (my family and i) worked out a plan where we would rma the modem to 3com (this was not easy, they tried to not cover it as act of god) and optimum online would lend us a motorola surfboard cable modem in the meantime. eventually, i got a replacement from 3com which [surprise, surprise] did not work, it had the same deficiency. the modem was not the one i sent though, i compared serial numbers. i still had the motorola modem, optimum online wasn't asking about it at all, and i rmaed the new modem. 3com sent me another modem, different serial number and this time it worked. after a week, the modem crapped out, same inability to transfer data. at this point, i figured there was no point in continuing because 3com was intent on offering a poor product. i still have the motorola modem which i emphatically endorse, but the 3com modem i wouldn't touch with a yardstick.

just sharing my experience, but thanks for the deal anyhow 😀
 
having to deal with this POS modem over and over again i can tell you the problem....

the firmware sucks....(check on the back of the modem for 3.1.0 or 3.1.0L) and 3Com doesn't support it...

here's the problem....

when a modem is first turned on it asks the provisioning system and CMTS for a TFTP file to set the parameters, the default generic DOCSIS bin works fine but is not configured to set all the of the specific values required for full DOCSIS functionality.. so after you modem has logged into the system, and been provisioned it's sent the specific 3Com bin, problem with that is the modems firmware is so fubar that it gets locked in a perpetual state of rebooting.....

so these modems will work until rebooted.... then they will not work until sent a generic bin, then they will work.. until they are sent the correct bin then they will work until they are rebooted.....

its a vicious cycle... that does not happen with any of the other 3Com cable modems...
 
ermular:

it's problems like that that make me intent on paying the 10 bucks a month to use the modem AT&T supplies. if i ever have any problems with it, or if it craps out on me they will just exchange it for a new one. and i can be guaranteed compatibility because it's THEIR modem.

ok, i guess i shouldn't rant about this too long, but i can't justify buying a cable modem when i'd probably have to wait 10 months to recoup the cost and during that time if it breaks or if i find out that its no longer compatible with my network then i'm SOL
