DCM476 modems bad firmware. TekSavvy replaced mine with a DCM475
I wanted to share my experience.
Switched from Rogers to Teksavvy.
Experience was horrible so far, but we do have a solution. (scroll to bottom)
With Rogers - everything worked. Time capsule worked automatically with the cable modem.
Switched to Teksavvy. Cheaper and Rogers wasnt willing to offer more usage. Went through retention dept and the most they offered was 20% off - but with their usage caps, it made sense to go to Teksavvy with their 300 gb limit.

Thomson DCM476 Changing DNS entry
I'm trying to change the DNS entry on my DCM476 when I enter
192.168.100.1 all I get is the modem's diagnostic page. How can I
access the modem page where I can make changes?
Thomson DCM476 - Are my cable modem stats good (pic)
This snapshot of my current diagnostic screen for Thomson DCM476 modem.
Are they in acceptable range or do you think i will need an amp (i am getting the Electroline EDA-FT08300 Active Return (8-port = 3dB forward, 0dB return loss)).
What are the ideal range of values for Forward and Return path (Power + SNR)? Is lower better for SNR for Return Path while higher is better for Forward Path?
And why do i only have 3 return path channels and not four. Has the entire industry moved away from 4? Cheap bastards
Cable Modem Thomson DCM476 (LED Light Display)
I bought a Thomson DCM476 cable modem (HW:2.1 FW:STAC.02.50). And I
recently signed up with Electronic Box for cable access. The Rogers
technician guy hasnt come yet (wont be til next week) but interestingly
when i plug in my modem i notice the LED lights show:
Power = Green (solid)
DS = Blue (solid)
US = Blue (solid)
Online = Blue (solid)
Link = Green (solid) >> when my Ethernet cable is plugged in -- in photo below it wasnt plugged in
My Thomson DCM476 LED display:
I dont officially have internet access when checking through my browser but do these specific colors (and state) for the LED lights indicate that all is good and i am merely waiting for Rogers

How do I change my MAC address
MAC addresses were designed to be fixed numbers that cannot be changed. However, there are several valid reasons to want to change your MAC address
Thomson Technicolor Cable modem DCM 476
Changing a MAC Address To Work With Your ISP
Most Internet subscriptions allow the customer only a single IP address. The Internet Service Provider (ISP) may assign one static (fixed) IP address to each customer. However, this approach is an inefficient use of IP addresses that are currently in short supply. The ISP more commonly issues each customer dynamic IP address that may change each time the customer connects to the Internet.
ISPs ensure each customer receives only one dynamic address using several methods. Dial-up and many DSL services typically require the customer to log in with a username and password. Cable modem services, on the other hand, do this by registering and tracking the MAC address of the device that connects to the ISP.

Change MAC address
DCM476 - DOCSIS 3.0 cable modem mac address
The cable providers allocate IP address using DHCP. It looks at the MAC address of the computer (or router) it is communicating with and goes from there.
Change MAC address::
I needed to get my IP changed so I called up my ISP and told them. It took them 10 minutes to reset it.
So,
1) Unplug your cable modem for about a minute
2) Direct connect your PC or laptop to the modem
3) Power On Cable Modem (on surfboard, wait for the "Online" light to come on constantly)
4) Wait another minute.
5) Repeat steps 1-3 for Router.
It might not be possible. It's assigned on your ISP's end. I've noticed the same thing with my SBC DSL modem though. I only get a new IP every month or so. My guess is that the IPs are assigned to the modem for long periods.

Factory reset not working on DCM476
[Cable] Factory reset not working on DCM476
1. Do a ipconfig /release in the command prompt on your PC before disconnecting it from the modem. This releases the DHCP lease.
2. Power off modem (as you don't want it to see your PC MAC again!)
3. Wait that 5-10 minutes.
4. Connect PC to router, connect modem to router. Power on modem.
If it still fails after step 4, clone the MAC address of the PC to the WAN interface of your router. Note: This doesn't cure the cause of the problem, only the symptom by making that router thinks that your router is the PC.

RCA / Thomson Modem Hack Discovered
An anonymous reader writes "Those un-employed modem hackers are at it again. The group known as TCNiSO has released a very interesting hardware modification for RCA / Thomson cable modems. The modification is done by grounding the bus clock on the serial EEPROM which throws the device into a diagnostic panic mode. Then by using the debug tools from the embedded console to reprogram the EEPROM, a user can permanently enable a developers menu which gives complete control of the modem, such as modifying the hardware addresses or flashing new firmware. Now if only these guys can figure out how to enable the Bluetooth features on my v710 phone..."
