Wireless & Wired Speeds

By jshep ·
I hope I do not sound like a complete idiot.

Comcast offers speeds of up to 6Mbps (6 mega bits per second).

802.11g transmits to over short distances up to 54Mbps.

How come my comcast connection seems much faster than my 802.11g connection?

Many variables not defined...

by gralfus In reply to Wireless & Wired Speeds

Are you talking about transferring files from one computer to another via wireless, or using wireless to connect to the internet versus using a wired connection, or something else?

If the download time from the internet (wirelessly) is truly faster than transferring from one computer to another computer on the same subnet, then there is a problem. You'd have to narrow it down systematically.

It could be the TCP/IP stack on either computer, the NIC on either computer, any firewall software you have installed, the access point between the two computers, and more. As you can see, there are many factors that could be influencing the speed.

Internet Connection

by jshep In reply to Many variables not define ...

I am talking about using the wireless to connect to the internet versus a wired cable modem connection from comcast.

Nothing is wrong. I am just trying to make sense of the speeds. Wireless is listed at up to 54Mbps and my broadband is 6Mbps, yet the broadband is faster.

Thanks

Wait...back up

Are you saying you have a wireless ISP? You can connect to this wireless ISP via something?

You need to define more. How do you connect to the wireless ISP? Are you sure it is 802.11g? If it is 802.11b, then you will only get 10mbps.

So here is the question. Your setup with comcast is:
Cable drop -> Cable modem -> ethernet out of cable modem -> NIC in PC

Your wireless setup is:
wireless ISP -> wireless reciever/Wireless NIC???

No wireless ISP. I use a wireless network at work and we have a T-1 connection.

I am positive it is a 802.11g and I get about 45 to 50Mbps.

Yes comcast is cable drop -> cable modem -> ethernet to ethernet PC NIC

Wireless - T1 -> Linksys router 802.11g -> Belkin Pre-N wireless PCMCIA NIC

If I get this right..

by jdmercha In reply to

You're comparing your Comcast speed at home to your T1 speed at work?

Cable is much faster than T1.

Are you kidding????

by Bruno Fonseca In reply to If I get this right..

You're actually saying that cable is faster than a T1. Maybe you can be right on the fact that when the connection reaches your desk, compared to the connection that reaches your desk when using cable it can be faster, but that depends on the employee size of the company that uses bandwith and other factors, but cable is defenitly not faster than a T1, Absolutely not. You have a T1 trunk and a cable line run to your house and then you will notice a difference.

Well.......

by CarlitosWay In reply to Are you kidding????

Cable companies claim they provide bandwidth service between the averages of 10MB and 2MB. (Depending upon your location, company, and how many people have cable in your vicinity.)

T1's that are under business level accounts are supposed to have a guaranteed bandwitdh at 1.5MB for a wide range of user's at one time. Cable speeds start to deteriote when you are using 5 users or more. There's no guaranteed bandwith on home cable lines. Thats why they have that 2-10MB range.

So technically, cable has a faster thoroughfare rate than a T1, but a T1 can provide the same
level of bandwidth for more users at that guaranteed 1.5MB speed.

By the way, the other speeds for Trunk lines are T2 and t3, 6.3MB and 44.7MB, respectively.

Hope this helps.

Some cable companies have upgraded.

by TonytheTiger In reply to Are you kidding????

and are offering speeds of 5 mbps or even higher.

Raw speed

by jdmercha In reply to Are you kidding????

There are many factors that will affect the speed you get. But cable has a faster raw speed than T1. To check what you get go to http://reviews.cnet.com/Bandwidth_meter/7004-7254_7-0.html. The result may not mean much, but compare home to work and see what you get for a difference.

OH!!

by jmgarvin In reply to

Ok I think I understand now.

The problem is this. As (more or less) a single user on your cable system you are getting about 3mb (up to 6mb I believe).

With the T1 you get 1.5mb and you have multiple users at the business. Plus you are sharing the 54mb connection the wireless provides.

Does that help?
