Need information on DSL Modem.
 
I don't think I need a router. I had a modem that just went bad and Verizon sent me a replacement "Router" (D-Link 2750B) for a replacement.
This is the first router I've ever owned. you only had to plug it in and everything seemed to work.
However after a few days with it, I hate it, my connections are slower, downloading anything is slower. Downloading a video, things will constantly pause for it to catch up with itself, I suppose.
I'm also pretty sure I am renting it also from Verizon, I say suppose, because I haven't been able to get through to them yet (that is another story)!
I checked it out on the Internet and it get's the worst reviews I've ever seen (Amazon), cost for one is about $25.00 for one if you look around, that should tell you something!!

So, I need advice on a really good full featured modem that I can trust. I can spend $100 or so but really have no idea what a good one costs.
Can you guys please HELP me, I know very little about modems and less about routers.

My system stays on about 12 hours a day, 8GB of ram, MSI mother board model 890FXA-GD70.

Your d-link is a combination dsl modem and router, called a wireless gateway device.

Perhaps something is mis-configured causing slowdowns. If you replaced an existing stand-alone dsl modem without any router, the new unit should perform about the same if everything is set up properly. Manual here: http://www.dlink.com/-/media/Consume..._Manual_US.pdf

A number of issues are present there. One is the possible modem. Another may be the line to it or nearby or downstream issues. Oddly enough attacks happen on mine all the time. Lastly is internal things in your home or such.

Usually you can log into the modem for some very detailed information. It is quite complex and almost no web pages sort out the various metrics.

To replace it you need two things at least. One is a compatible modem (or router/modem) and the other is all your sign on information to include some possibly very specific local data.

When I mean compatible I mean both in terms of signal like ADSL2+ and one rated for your speeds. Part two of that is one that Verizon may allow on their network without too much hassle.

Find out what you can use then start search.

Look to combination of places like Amazon and also places like Newegg or Tigerdirect and others.

Don't forget that some simple things like dsl filter going out or small wire touching or even simply resetting the line may fix this.

The good news is you started off OK so you at least know it can work.

Hi Jefro, I don't want to even try fixing the router. When it can be bought for 20 some dollars I pretty well know what kind of future the two of us would have! So I definitely want to get a new one that is higher in quality and functions. I simply can't take getting up every morning wondering what the heck will be wrong with it now!

When a modem is in full compliance with ADSL2+ shouldn't it work fine with Verizon and connect at whatever speed my contract calls for (that's another story)?
My home phone is as limited as I could get and the DSL connection is supposed to be High Speed. I'm paying $82.00 every month. When downloading a movie my speed runs from 0 to 90 something Kbs, I sure don't call that High Speed.
Plus, I'm sure I am renting the router they sent me so I want my own, I see no reason to pay them for renting a modem.

Is there a really good brand/model of modem you can tell me about? I just want to get this over with and get a stable connection.

Emerson 12-13-2015 02:57 PM

You better run a speed test, downloading a movie can be slow for various reasons.

jefro 12-13-2015 07:42 PM

"shouldn't it work fine with Verizon "
Maybe, sometimes not. You'd think it should but you hear a number of stories. Once you put your own modem on the line, no ISP will assist you.

I bought an actiontec a few months ago but haven't gotten around to putting it on ATT. They stopped making that model but it was well rated but I did search for specific notes about ATT.

I agree. It might be difficult but I would try and get a hold of Verizon to see if they can help you troubleshoot what's going and perhaps resolve the issue. You could also inquire what other modems their service supports. Doing it this way might save you time and money, in the long run. :)

I found the product support page here, in case anyone wants to take a look.

Hi,

Verizon should be the one to solve your issue(s). You can purchase the required equipment but it must be Verizon certified. No support thus not configured for their DSL rack if you choose outside of Verizon. I would be in direct contact with Verizon and tell them you are not getting the data plan you are paying for.

I am not sure where you are located but my data plan is just 29.95 for 11 MBps download/ 1MBps upload service with a supplied modem with 4 ports & wireless. No rental, contract lease or service fees. $80 for your service plan seems high. Talk to the representatives to see how you can get this resolved.

Go in bitching and you will get no where! I have a very clean line (-9db) & am just 2 blocks from the PO (<1200 ft). Find out by requesting a line test for noise & equipment test(s). Request that your line & filters are checked along with a noise levels test. Clear line is a must for DSL. You should make sure that all phone jacks have a DSL filter between the phone device and the jack. Plus be sure all your attached devices are functional and not introducing noise or poor signal quality.

Yes, the DSL modems do fail, I am on my second modem that was replaced free of charge since Verizon will get no money for no service. Be nice and see how far you will get. Overly aggressive and that representative will not be on your side. Have all your data and issue(s) compiled when talking to Verizon. It required me to get to higher level technical support to get things right.

Persistence, courteous & honesty will go a long way to get your issue(s) resolved so you will be on line again.

EDIT: Is this your modem, maybe this PDF will help; http://www.dlink.com/-/media/Consume..._Manual_US.pdf
Hope this helps.
Have fun & enjoy!

Guys I did the speed check.

Down load Mps Up load Mbs
ZD Net 0.7783

C/NET 0.79
0.81 .68



I believe it is prudent that I have a talk with Verizon, if I can get through to them by phone!

Thanks for everyone's help and the links. They will be useful.

I have lived in a few places. The so called tech will come out with a $4000 meter that can do 10,000 things. Unfortunately he only knows how to use 3 of those functions. Took me 2 years to get all the line to one house fixed. You need a good tech that knows two parts of the story and you can never be allowed to talk to that person.

One is the wire, physical wire to your "home office" It may be near or quite far. They can ring the line and get a guess but it takes a good tech with at least a TDR to scan the line for imperfections and open ends and resistance issues.

Two is the million of gizmos past the home office. From the local DSLAM slot to the DSU/CSU's down the path and media conversions.

You will never get to talk to the one guy who actually knows how to get your system fixed.

Buying a new modem may simply make things worse.

I'd still log into the modem and see what diag logs exist.

I don't know, back in 2001, when I first moved into the apartment I've living in now and was using dial-up, I couldn't connect no matter what I tried. I called Qwest (as it was called back then) numerous times to try and get them to fix the issue but each time they told me that they don't support dial-up over their lines. If I remember correctly, I got "linebacker" put on the account (a extra service that covers the line inside the residence.) Either way, Qwest sent out two or three male technicians, each of them said they couldn't find any problem with my line from the "box" to my jack. The last time, a female technician came and I explained to her that I really need to get this connection working as I depend on it, in part, for my work. She said she would take care of it in a way that seemed to suggest that she knew what the problem was and how to take care of it. Sure enough, later that day, I was able to get online using dial-up and never had a problem with it until I started using DSL in 2009. ;)

Praise God!! :)

You're welcome, let us know what you find out. :)

You should compare your upload/download speeds against what you're supposed to have with your dsl plan. They are pretty slow!

FWIW, I have verizon and the few times I've needed to call support it's been pretty painless getting to speak to a tech. Maybe I'm just lucky though :)

Lola Kews 12-17-2015 03:54 PM

Something I forgot to ask, Is ADSL2+ backward compatible to ADSLN ?

jefro 12-18-2015 03:20 PM

The modems have full specifications listed on the package or in the sales documentation.


Yes, you are correct. Once in a while you will get a male or female that can help you but it seems very rare.
