10/100/1000mbps Network Adaptor

[holycpu]

I am using Cable internet with 5 MB download/ 1 MB upload speed currently.

1. Is it even possible to get 1000Mbps from my cable connection if I am using a Wireless-G router because my cable internet is connecting the router then the router connects to my desktop tower if my network adaptor is 10/100/1000 mbps? (If 1000 Mbps is not possible, how about 200 Mbps? )

2. The network adaptor I am planning to get is D-link DGE-530T, saying Auto-negotiating 10/100/1000Mbps, I know that it will be running either 10 or 100 or 1000 Mbps but, will it able to run at 200 Mbps or 500 Mbps?

3. How can I run my network at Full duplex mode?

Thank you

1. Most residential cable service never goes above 5 mbps. Highest I have seen is 8. Even business doesn't go much higher, it just gives you better upload speeds. Your actual network connection between desktop and router would be 100 mbps, I doubt you have a gigabit router. The fact that the router is wireless G doesn't matter if you are running a wire to it. Wired connections will be 100 and wireless will be 54.
2. I am a little lost on how you are expecting these half speeds. They either run at 10, 100, or 1000. Wired connections don't drop down. Maybe you are thinking about how wireless will drop to a lower speed to compensate for a poor signal.
3. Your network should run full duplex automatically as long as you are using a switch (or a switch built into a router) and NIC cards that support full duplex. Most do, but I have a couple that don't. My switch has a light that shows me if the link is full duplex or not.

For #1, I am really stupid at computer. There is something I don't understand. If cable only give 5 mbps, then how come my actual network get 100 mbps between my router and desktop since router is connecting to the Cable ?

Thank you for your reply

Your actual network is 100 because if you have more than one computer connected to that router, you can share files between those two computers at your full network speeed, wheras if you connect to the internet, you modem is only going to supply 5mbps.

If I change my router, can I get 1000 Mbps network speed between computers?

Yup.

Not to confuse things further, but actual real world transfer speeds on gigabit aren't nearly close to 1000 mbps for a number of reasons, normally because your computers hard drive can't keep up. It will be faster than 100 though

A Wireless Router is a combo unit of Routing circuits, Switch, and Wireless Access Point.

Each one of this section has its own max. ?Speed? that it would work in when computers attached to the device exchange Self Generated information between them (I.e. Local LAN Traffic). The Speed capacity of these sections can not change the original speed of the Internet. If your Internet signal is 5Mb/sec. it is not going to increase because the switch is 1000Mb/sec. capable.

If you have $1000 it is not going to turn into $10,000 when you put it into a bigger Wallet.

Speed expectation of Ehernet Home Networks using Windows98/2000/XP.

This numbers are very general rule of Thumb and might vary according to individual Hardware/Software Settings. Wireless numbers relates to default setting when the source and the client are few feet apart.

(b=bit, B=Byte, 1Byte = 8bits)

Wired 10Mb/sec. Yields 6-8Mb/sec. (.7 ? 1MB/sec.)

Wired with 100Mb/sec. Yields 60-80Mb/sec. (7-10MB/sec.)

Wireless 802.11b Yields 4-8Mb/sec. (.5 ? 1 MB/sec.)

Wireless 802.11g Yields 16-22 Mb/sec. (2 ? 2.8 MB/sec.)

Wireless 802.11g (Super/Booster etc.) Yields 28-42 Mb/sec. (3.5 ? 4 MB/sec.)

Wireless per 802.11i Yields x2 x4 more than 802.11g at close proximity.

Consumer?s available Internet connection speed varied according to ISPs.

The best Cable connection is currently 5-6Mb.sec. DSL 3Mb/sec.

I.e. Quirky Wired Network that uses 10Mb/sec. Network card might affect fast Cable Connection.

802.11b Wireless might slow down good Cable or DSL connection.

Otherwise the ?Speeds? of the other commonly used standards has no positive or Negative affect on your Internet Speed.

Thank you

call verizon and ask for a quote for a couple of DS3's to your house

then find a router on ebay that will handle them
