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

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.

TekSavvy Cable Internet & Double NAT error

I'm hoping that someone's been in a similar boat or has a few tips that could fix this. I've just recently switched from Rogers High Speed Internet to TekSavvy Internet. I'll go ahead and give you the network info...

Cable Modem: Thomson  DCM476
Airport Extreme running 7.6.1
Airport Express running 6.3
MacBook running 10.6.8
Mac Mini running 10.7.4

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)

I switched from Roger to TekSavvy this past week... had Rogers for > 1 year and everything worked smoothly. Switched occured this past Thursday and ever since, I've had problems with Double NAT & No DNS error... let's just say that watching streaming video has become a tedious process of having to get up every 5-10 minutes or so to restart the clip (ie. watching TV shows on CTV.ca for example) is a task I wish on no one!

I contacted TekSavvy support and they've basically said "NOT OUR PROBLEM. FIGURE IT OUT". To be honest, I was floored. Not the type of service I was expecting from what was a tons of referrals from friends and acquaintances.

I googled a few variants but nothing appears to stick out in terms of steps to fix/resolve this issue.


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.

I cancelled Rogers. Same day I got Teksavvy. I ended up buying their cable modem. DCM476 for $100.

Day 1 - the day of the switch Teksavvy they kept saying - it should switch over automatically, just be patient. It never switched over automatically.

Day 2 - called and got bounced around. Note - you need a PC to troubleshoot. This doesnt work well for me as I have a macbook air and the apple time capsule. Not friendly to mac. No internet for the day.

Day 3 - I finally borrowed a laptop from work. I plugged in laptop to modem. It works on direct connection. But it doesnt connect to airport time capsule. I have latest firmware for everything @ time.

The airport time capsule worked with Rogers. However it doesnt work for Teksavvy.

Note - i probably have had 6 calls with Teksavvy - basically I got the run around - it works on a direct connection - that's all we need to do - tough luck.

I saw another website - and tried to get them to give me the DCM475... but they dont offer that anymore.

Honestly - they need to know this problem and at least have some support for this. They should know this error and tell people - not force people to search the internet for solutions. It's ridiculous their attitude. That might be the worst.

So it didnt work.

Is it Teksavvy's problem? or an Apple Time Capsule problem? i.e. why did ATC not connect to the DCM476?

To me - the ATC connected to Rogers - so it's a Teksavvy prob.

Day 4... I was able to get a cheap router from work.

*** SOLUTION: for me was to get another router. Just a cheap one. DCM476 -> connected with cheap router -> which connected to the Airport Time capsule.

So my problem is solved. After many hours and lot'sve of problem solving. What a waste of time. We'll see how my experience continues with them.

I would not recommend Teksavvy to anyone.
