I would negotiate with suddenLink for a free try out, ie if I cancel the service with in 2-3 weeks, there will be no charge.

For cable service, you don't have much control on the modem, regardless whether you rent or own the modem. Basically, it's just a plug and play little 'back box'. You need your own router here, and a good router is always a good investment regardless what service you have at time.

For cable broadband quality, the coaxial cable itself plays an important role. The outside (and buried) cable need to be RG-11. It's help if you are around when the technician come and install, just ask he/she to measure the signal strengh at the tap/box and at entry into the house. The two readings should be the same. If there is a drop off at the house entry, you should demand the line to be replace with new RG-11 cable, otherwise the quality will be suffered.

PS.
$10/month for modem is rather high, Comcast charge me $5/month, and their modem has backup battery installed.

Useful info there, and I thank you! I will give them another call in the morning and ask some more questions with the thought of a trial period in mind ... and I intend to wait and see what the installer might have to say about any particular modem. Radio Shack is just down the road here with a Motorola SURFboard® SB6120 for $100.00, and I can easily go get one of those in a matter of minutes if I do not like whatever the installer might bring along for $75.00. Or, I could use a rental for a month to get a feel for things and decide after that. But yes, a separate router or hub -- Is there a difference?! -- is definitely the plan here. I already have a couple of 10/100s, but no wireless ability.

Not to argue, but to learn ...

What is the harm of that TCP delay? My overall speed averages out well, and I have yet to see any packet loss.

Either way, however, I am going to at least find out what cable is available here where I live.

I suppose the delay being long translates to you/other party hearing things that much later. 300ms is almost 1/3 of a second; a long time.

Here is what the whichvoip site says:

Delay- Usually measured in milliseconds. Obviously the longer the delay the more difficult a conversation becomes. Anything under 100ms is good. The ITU recommend that one way delay should not exceed 400ms for acceptable speech quality.

I think $100 for a cable modem is kind of high. You can search for brand new docsis 2.0 modem for $50 something or less. Moto SB5101 for example. docsis 3.0 modems are more; depends on if you want latest and greatest for future growth.

Ah, got it! I was only thinking of the delay ultimately helping to assure zero packet loss and I never made the logical conection to the noticeable delay my wife and I experienced while test-calling ourselves (Ooma to landline and vice-versa) while side-by-side right here in the house!

The future is definitely part of my thought there, but yes, I do know where to get a 2.0 for about $50.00. In the morning I plan to ask suddenLink about speeds and protocols or whatever, then figure out what is most prudent.

Update:

I called suddenLink to see what my cable speeds should be after I get connected next week, and I had unknowingly signed up for the same 1.5/256 I presently have with AT&T DSL ... so I cancelled the installation. I had done my research beforehand and had not found any mention of such a slow connection, and the sales rep who took my order said nothing at all about different plans!

There is no other cable available here where I happen to live, so I will just have to set my new $45.00 Motorola off to the side for a while and live with what I have.

I just found this at another site I frequent:

Comcast advertises high speeds but they accomplish these speeds by nano-second bursts of extremely high speeds followed by long periods of no speed. The speed graph looks like a picture of the Himalayas!


That is exactly what I sometimes get with AT&T, and now maybe I know why!
