TekSavvy Cable Internet & Double NAT error

Good evening,


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 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.


Thanks :-)

Anytime you change ISPs or networking hardware, it is always a good idea to perform a complete power recycle of your networking components.


I would recommend that you do the following as a minimum:

  • Power-down the modem, AirPort base station, and computer(s).
  • Disconnect the AirPort base station from the Internet broadband modem.
  • While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
  • After the base station resets, go ahead and power it back down.
  • Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
  • Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
  • Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
  • Power-up your computer(s).

In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

Thanks guys, I called them and they told me that my dcm476 has the new firmware (after they had me check it) they told me that they no longer swap out the units since this firmware fixed the problem. I am still having issues with my xbox or ps3 connecting some times and my iMac seem randomly does not work on pages like google or facebook. I'm starting to think maybe it is an issue with my wireless router (dlink dir-857 n900 media router). They suggested that I call dlink and try to get them to help me in making sure all my settings are correct.

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.


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 the thread - 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.

Thank heavens I found this thread! I was going crazy trying to troubleshoot this. I first noticed the issue when Teksavvy had that major outage and we were without service for over a week. I ended up switching out my Airport Extreme for an old SMC router I had lying around.


Today, the internet was again on the fritz, so I tried troubleshooting again, and hooked up the Airport Extreme. All worked well for about 20 minutes and then everything fell apart again. I called Teksavvy to see about outages again, and got a less than helpful CSR rep, who sounded like a Bangalore outsourced company following a check list (is the modem plugged in, etc.) I couldn't get the AE working consistently, and as soon as I switched back to the old router - it all works again.


Now I'm going to have to check to see what modem I've got. I know it's a Thomson, and the firmware details are:

Status Code: Operational
Software Version: STAC.02.16
Software Model: a81a
Bootloader: 2.3.0

I think I've had it for over a year, so I might end up having to buy a new modem. Weird that it worked before and now stopped working?

I as well have had great service from TechSavvy. Speed has been acceptable, allowing me to easily stream NetFlix. I have never reached any kind of max download/upload limits; I don't think they track Ontario cable usage... I figured this out after I was concerned about the amount of streaming I was doing and found their was no way for me to see what I was using. I'm on their Extreme Cable 28 plan.

When Teksavvy (or any company) does a very clear mistake and does not compensate your for that mistake.


Find a "consumer court" "small claims court" in your jurisdiction, check their rules, ensure that your case is legally solid (e.g you have emails or other records of them promising something and not delivering, loosing internet connectivity for a long duration and not getting a reduced bill etc).


Sent a "WITHOUT PREJUDICE, formal notification - asking them for compensation, listing the difficulties that you have undergone because of the loss of internet connection or whatever"


They'll mail you back with a stingy offer (we'll send you a free modem, free 1 week internet), hike it up to the level you want, If you are unhappy, be ready to to go to the court.


Small claims court usually do not require a lawyer; so the expenses are low. I got a good "climb down" from TekSavvy - it should be similar for any company that takes customers for a ride assuming customers won't take the pain for suing.
