CAble Modem/Speed

[Guest Dan R]

I recently upgaded my service to a 20 Mbps cable speed through my provider.

Realizing my old modem was only DOCSIS 1.0 compatible, I went out and got a

new Motorola SB5101 modem than can handle DOCSIS 2.0 and upstream speeds of

30 Mbps. I can only seem to get a maximum speed of 7.2 Mbps. The cable

company says an acceptable level should be around 12 Mbps, and after calls to

their tech support line they cannot seem to figure out why I can't connect at

a minimum 12 Mbps. They said the connection is excellent with no packet loss.

I do have a router, but when I hook the cable modem directly to the computer

it gives me the same max speed of 7.2 Mbps. I also turned off Zonealarm, my

Avast Antivirus, Winpatrol, Windows Defender, and two other things that were

running in my taskbar, with no changes. I was wondering if anyone had any

ideas what I can do or settings to change to get me to the higher speed?

 

I am running Windows XP SP3, Pentium 4 2.8 Ghz, 1 GB of RAM, and a 128MB

Nvidia 6600GT video card. Any help is appreciated. Thank you.

What are you using to test speed?

Tried http://www.speakeasy.net/speedtest/ this?

Re: CAble Modem/Speed

 

I used a couple sites, but the main one I use is the cable company's own

speedtest site, but I've also used speedguide.com and speedtest.com

Re: CAble Modem/Speed

 

Most older routers only have a 10Mbps WAN port. Check your maximum WAN port

speed rating on the router. Also, what speed is your network card?

 

Did you mean "downstream" speed of 30Mbps (upstream is from your computer to

the Internet)?

Re: CAble Modem/Speed

 

I was told "upstream" is a different thing that "upload" speed and that my

upstream speed specifically needs to be above 20Mbps to handle the speed.

They said it is different than upload speed. Yes, my router is older and it

says in the manual that I do have a 10 Mbps WAN port (this is a wired

router). I've asked several companies, including my cable company, Linksys

customer service, and other if that specifically mattered and would hinder my

speed. All answered no. It does say in the router manual that while the WAN

speed is limited to 10 Mbps, the LAN ports can run a max speed of 100Mbps. I

dont know (and cant seem to get a straight answer) if the WAN speed does in

fact matter. If so, shouldn't I be able to get close to or at 10 Mbps? Also,

I directly connected the modem to the computer without the router, and I get

the exact same max speed: approx. 7.2Mbps. The netword card says it is a

10/100 network card. How can I check the speed of it? It is an intel one

that came pre-installed on my Dell.

What does this have to do with the OS? Nothing.

 

Ask elsewhere

Re: Cable Modem/Speed

 

Dan,

 

Upstream = upload = outbound from your computer to the Internet

Downstream = download = inbound from the Internet to your computer

 

Six of one, half dozen of the other!

 

Having a router with a 10Mbps WAN port caps all upstream/upload or

downstream/download speeds to a maximum of 10Mbps, as it is the weakest link

in the chain between your computer and the Internet via your provider.

Whoever told you otherwise was wrong, if indeed they were referring to

**20** Mbps and not **2** Mbps speed. You CANNOT push 20Mbps through a

10Mbps connection, period! It would be the same as trying to shove a 20 foot

diameter steel ball through a pipe that starts out at 30 foot diameter

(30Mbps at the cable company) but has been hammered down to 10 foot diameter

in the middle of the pipe (your router's 10Mbps WAN port) before it gets to

your 100 foot diameter (100Mbps) router LAN port and laptop network

card...not going to happen...from either end!

 

You stated that you have tested it with your laptop directly connected, and

if it truly has a 10/100 card that is connecting at 100Mbps, then your

problem lies elsewhere, i.e., between the cable modem and the provider. When

you connect your laptop directly to the cable modem, what is the link speed

listed? It should show connected at 100Mbps. If it does, and if they tell

you that you are paying for 20Mbps speed, then you should get close to that.

I have 10Mbps downstream and 1Mbps upstream, and my actual speeds are about

9.8Mbps down and 940Kbps up. I get almost exactly the speed for which I pay.

 

Again, upstream or upload speed is from your computer to the Internet (mouse

clicks on a web page, sending an email, uploading a picture to your own web

site or one that provides a picture-sharing service). Downstream or download

speed is from the Internet to your computer. Your mouse clicks on a web page

are upstream/upload packets, while the actual page you see is a

downstream/download packet. Watching a movie or listening to Internet radio

is DOWNstream/DOWNload communication. Think of upstream/upload as OUTbound

packets from you to some site or person, while downstream/download are

INbound packets to your computer. The data sheet for your Motorola SB5101 is

wrong when it states that upstream capacity has anything to do with surfing

speed. The speed from the Internet to you via your cable modem is DOWNstream

or DOWNload speed. When you are browsing, you are downloading web pages, not

uploading them. Browsing speed is mainly dependent upon downstream speed of

the images to your computer. You could have 128Kbs upstream speed and 20Mbps

downstream, and you would be BLAZING fast at browsing.

 

If they are giving you 20Mbps **upstream** speed, that is **EXTREME** high

speed for UPstream or UPload speed on cable. I do not know any cable company

in the USA that even has that upstream speed. Verizon FIOS has 20Mbps upload

and 20Mbps download speed for $65/month, and 50Mbps down with 20Mbps up for

$145/month. See

http://www22.verizon.com/content/consumerfios/packages+and+prices/packages+and+prices.htm.

 

A typical offering from Road Runner cable (in the USA) is 6Mbps down and

512Kbps up for about $45/month. They have 10Mbps down and 1Mbps up for

$55/month.

 

Regarding the router's LAN ports, if you had two computers on the LAN that

had 10/100Mbps cards in them both, they could talk at a max of 100Mbps to

each other, but would still be limited to 10Mbps going in or out of the

router from or to the Internet. Realistically, low-end 10/100 networks cards

such as Realtek only work at about 35Mbps on a 10/100Mbps network switch,

while Intel and 3Com 10/100 cards usually run around 93Mbps on the same

switch in the same computer. I have replaced MANY Realtek and other low-end

cards with Intel or 3Com cards. Cheap 10Mbps network cards usually run

around 6Mbps to 7Mbps.

 

Verify that your laptop has a 10/100 card connecting at 100Mbps. Go to

Dell's site at support.dell.com and put in your service tag. Then look up

Original Configuration.

 

I would request a higher support tier. Every time my speed goes down, it

usually drops to about 2.5 Mbps downloads, with upload unaffected at 1Mbps.

They usually take a day or two to get it back to speed. The last time it

happened, they sent out two techs, who replaced the cable router (I have

five static IP addresses), then replaced some stuff in the junction box

outside, then went down the street and found some corrosion. It still took

two more days for them to get it right. I am looking at FIOS pricing right

now for that reason.
