Metrocast 75Mbps internet vs TDS telecom by Anura Guruge

Click to ENLARGE. My download speeds, from “”. Performance on Saturday night highlighted. Dramatic uptick from the 15(+)Mbps I was getting from TDS Telecom.

The one major inescapable problem (other than outages, of course) of getting Internet from a cable provider is that you are always getting shared bandwidth. That is a fact of life. You are on the cable — albeit with today’s cable carrying 8 or more high speed channels. But given that you are on a shared medium you always run the risk of losing bandwidth when there is lots of other traffic on the cable.

This is why I was happy to have a dedicated, fiber to the house, service from TDS. With that I had dedicated bandwidth until I hit TDS’ servers. But TDS Telecom, alas, despite its promise of gigabit Internet in the future, can only offer me 15Mbps download. I wanted more. That is why we ended getting two fibers to the house for a total of 30Mbps — though I split that into two networks, keeping 15Mbps dedicated for my main PC.

Well on Wednesday, as I documented, I got the MetroCast 75Mbps/5Mbps Ultra service. It works. Definitely more bandwidth.

But, I was NOT going to ditch my TDS connections UNTIL I saw how MetroCast performed over a Saturday night — the night when, typically, there is most traffic on the cable. Last time I had MetroCast, 4 or 5 years ago, bandwidth used to plummet between 8 – 11pm on Saturdays. Now to be fair I don’t use my PC, much, during that time. So it is not a great hardship.

The MetroCast folks assured me that my bandwidth will not drop. I knew that that would NOT be the case. I knew that there will be SOME degradation — the question was how much.

My computer guy, Shane Selling of hexacopter, who lives in Laconia, N.H., has had 75Mbps from MetroCast, on a beta test basis, in October. He tried to assure me that I would be find.

But, I had to see it myself. So I made a point of testing the bandwidth, Saturday night, using “”.

I was impressed.

I had set an acceptable threshold of 70Mbps/3.5Mbps.

As you can see from the image above, the bandwidth did fluctuate, more than normal on Saturday night. But it stayed well upwards of my threshold.

Yes, I appreciate that this could change in the Summer when we have more people on the road! Risk you take.


I do use my own SurfBoard SB6141 as opposed to the SB6121 that MetroCast provides. This might be a FACTOR as to why the bandwidth did NOT degrade that much.

The SB6141, in the case of download, can bond together 8 cable channels. The SB6121 can only bond a maximum of 4. That is why I coughed up the extra $25 and got the ’41’ rather than the ’21’. When the service was installed we checked the modem for signal strength. You could see 8 channels.

I just took a screenshot of it. 8 channels.

The 8 cable channels I see on MetroCast 75Mbps with my Motorola SurfBoard SB6141.

I also noticed that ONLY 2 channels are being bonded for Upstream. Upstream bonding is the same on the ’41’ and ’21’ — i.e., up to 4. Hhhhmmm. Interesting that MetroCast only permits 2 channels to be bonded, BUT given that they are giving ‘us’ 8Mbps, as opposed to the 5Mbps, they promise, I can’t complain.

But, for now, per the claim I made to ‘all’, I will cut over to MetroCast and ditch the TDS connections — until they have gigabit. I have no contract with MetroCast. So I can cut over whenever.

I will keep you posted.

I do realize that it will not be all smooth sailing. 90 days after I ditch my TDS connections I will again be treated as a new customer. I would then be able to get a 2Mbps connection for $15/month. I might do that, to serve as a backup, and get a $65 TP-Link WAN port aggregator.

But for now it seems I have sticking with 75Mbps Metrocast.

I will do a post shortly on what my new network will look like.
