Max speed of 15/2 Mbps on 25/2 conneciton, could it be equipment?

post #1 of 17
Thread Starter 
Hey everyone. Appreciate your help on this one.

I recently upgraded my connection from 12/1 to 25/2 Mbps with Cox. Sadly, I did notice right away that the download speed increase was marginal at best. Upload is perfect (double as it should be), but downloads max at 15 on my desktop with a b/g adapter, and on my n adapter laptop I'm getting 20.

However, Cox is generous, and my 12 use to get 15 all the time, so I was expecting somewhere around 25-28. Normally I'd just think it's their connection, but after running tests over and over, and my laptop getting a completely different number than desktop (15 vs 20) and still not reaching the limits, something must be up. Any suggestions on where I should start?

Cable lines in the house are relatively new (not even 8 years old house) so I don't see that being a problem, however, the modem might be old. But can't imagine the modem could be the issue? Networking is my expertise, so I'm lost here folks. Equipment specs below:

Modem: Ambit Model U10C018 (online brochure show max speed of 30/48 Mbps)
Router: D-Link Dir-601

Suggestions? Thanks!

tell them to reset your connection through chat or telephone. I was having issue with my internet being so slow and after 1 hour of chatting with them, the technicians were able to reset my connection to their server and my connection was back to normal speed.

btw: the modem speed is only the "network speed" which is much faster than internet speed. So 30/48 is irrelevant in this case.

I will definitely call them tomorrow (closed now).

Side note, do you think it's my modem or you think my modem is more than capable? I think it's a really old model, but again, networking isn't my strength.

When I upgraded my internet plan I didn't notice much of a difference, and that was going from 1500/256 to 20000/1500. I upgraded to an ADSL2+ modem and the difference was night and day.

A lot of people like to go for aftermarket modems for high speed connections, you should be able to find how to set one up on Cox.

But, I'd go with a reset first, see if that does the trick.

You mean call them for a reset right?

The weird thing though is that I'm getting two completely different speeds. I get a 15 Mbps connection on my desktop (b/g) and 20 Mbps on my laptop (n), could that be simply because of the b/g vs/ n? Seems really odd.

I knew this "free" upgrade from Cox would cost me haha.

Ah, that does seem a bit odd. I'm not too good on wireless networking, so I'll let others chime in on that aspect.

the roads on the internet differ. Your bandwidth maybe 25 but the throughput is the real number. It is influence by a lot of factors

30/48 should be the forwarding capability of the device.
100 mbps would be your local link speed.

Different situation, standard DSL (non ADSL2+) protocol doesn't support over 8 mbps.

How saturated is your area with Wi-Fi? 1.5-2 MB/sec (12-16 mbit) is about the limit for G as far as actual throughput.

Do you still get ~20 with a wired connection? Have you tried to change the destination server on Speedtest?

Hey folks.

I have not tried my laptop wired, I'll give it a shot. So with a G adapter, my limit is roughly 15-16? What about with an N adapter?

I have tried different speed tests on different servers, and still the same results.

And as far as wifi, there are only 2 other connections besides mine (live in a condo). Let me try the wired portion and see how that goes.

Spoony- I do realize that numbers can change and there are a ton of factors, but when I had my 12/1 with cox, I got 15/1. So when I update I get 15/2 and 20/2 on two different devices, but don't approach 25 at all. Now, maybe I'm misunderstanding, but those quirks make me believe that it's my equipment. No disrespect to you though, because I know so little about this stuff, so if I'm wrong I apologize.
