SB5100 from EBay, not working on Comcast?

I picked up a used SB5100 on eBay for $12 that I thought I could use to stop paying the $5 monthly rental from Comcast. I swapped it out, called Comcast, and they said they couldn't activate it. Here's what shows up on the Web page for the modem...

Software Version: SB5100-2.3.1.6-SCM01-FATSH
Hardware Version: 1
MIB Version: II
GUI Version: 1.0
VxWorks Version: 5.4

Does it make sense that this shouldn't be able to be supported on Comcast?

Chances are it is a stolen modem, or one attached to an account in arrears.

Ebay - SCAMMERS MARKET. Be very careful shopping there, paypal is no different.

You can try posting your problem in the Comcast Direct Forum along with your HFC MAC address.

It looks like the modem is running pretty old firmware and that might be causing issues. SteveTeow See Profile can take a look anyway.

traceback is an issue for them.
If you get sued by the mpaa for pirating, the modem is how they find you.

You know they could do it, but they wont.

I have a 5100 series working just fine.

I would never have trusted a modem off Ebay though, odds are its still tied to an account somewhere. And if it was a rental that means its still technically comcast property.

Personally id find out if the area has DOCSIS3 and just get a 6100 series off Newegg or from a box store.

I advise people just to buy modems brand new and factory sealed. Used modems could be stolen, unreturned equipment (many times rental modems are the same ones sold in stores) or linked to an uncollectable account.

I'm not sure on this one but if you have a Best Buy near you that sells EMTAs, I'd just buy one of those in case you decide add voice later.

All of my CPE (including my EMTA) is customer owned. The only Comcast owned equipment in my house is the CableCards in the two TiVO boxes I own.

Comcast would only know if it was stolen if it was registered to their network. From the firmware version listed "SB5100-2.3.1.6-SCM01-FATSH", I have only seen "NOSH" on Comcast's network for that modem; not "FATSH".

A quick google of
SB5100-2.3.1.6-SCM01-FATSH
shows that firmware was widely used by modem hackers (mostly europe and is now blocked on all D1.1 and up systems, and eventually locks out the modem.
Someone sold you their garbage modem which they bricked while attempting a hack, and they will use your money to buy a new one.
As said above, avoid ebay or garage sales and buy a modem from a reputable vendor you will sell come out ahead within a year.
I agree with a D3 modem (for ComCast systems, some other ISPs are being slower to adopt D3) but recomend against eMTA/all in ones.

Excellent idea! Pass your problem on to somebody else, who will then post here about their bricked, eBay modem.

Or did I miss the [sarcasm] tags?

He at least deserves to get his money back. Yes, it is a viscous circle.

It's not bricked. The diagnostic page is accessible. Just presumably hacked.

Best to just advertise it as a modified modem & sell it Ebay.

It's only grief for the buyer that doesn't know what it is. Fully disclosing what's been done to the modem & selling it "as is", is up to a the buyer to know what they are getting into.
