I have two computers both with gigabit network cards. The router that connects them is a 100mbit router, and the distance between the computers is relatively short (only a few meters:) ). When I transfer files between the two the speed never exceeds 10 or 11mbit. Why is this so? :confused: :sick:
if the cards have automatic speed settings, change it to 100mb. Can't you move the mouse over the connection to see how it's connected? The transfer will when use the speed of the lowst card. A bad cable could also cause the problem lots of data has to be sent.
Yes, AutoSense is usually not good to use. Always set your cards to a specific speed.
Also, try changing the ports that the cables are plugged in to. May be an
issue on a particular port.
hmm I've got good quality expensive cables:D
ummmmmmmmmmmm how do I change that autosense thingie?
Win XP:
Controll panel->System->Hardware (tab)->Device manager
choos your network card. And find this setting:
aha found it. now whats the difference between full duplex and half duplex? :confused:
Full Duplex
I was going to say that one is half of the other but I didn't ;)
Copy/Paste..:)
Quote:
Refers to the transmission of data in two directions simultaneously. For example, a telephone is a full-duplex device because both parties can talk at once. In contrast, a walkie-talkie is a half-duplex device because only one party can transmit at a time.
Most modems have a switch that lets you choose between full-duplex and half-duplex modes. The choice depends on which communications program you are running.
In full-duplex mode, data you transmit does not appear on your screen until it has been received and sent back by the other party. This enables you to validate that the data has been accurately transmitted. If your display screen shows two of each character, it probably means that your modem is set to half-duplex mode when it should be in full-duplex mode.

hmmm interesting. So I should put it on full duplex right?:)
:) yeah...:)
Edit: Just as an explenation. The protocolls checks for collisions anyway. So you don't have to be too affraid of it.

So, I gather that it worked? :wave:
bleh haha I forgot to say...Quote:

If that doesn't resolve then I can only assume that its my crappy router. (Wireless-B/Netgear) :sick:
Remember that 100MBit is just theoreticaly...;)
bleh wth? :eek2:Quote:

so hmm
need to try that on the other comp later on and update you guys on it...
Because of the collisions. Well not sure how fast it usualy goes over a 100Mbit connection if you are just copying stuff. But if you are playing games and so on your are bound to get collisions, and then packages has to be resendt. So the actual data transfer will drop, but it still sends in 100Mbit rate though. But it just doesn't look like it because it has to resend so much all the time.

MegaByte = MiB
MegaBit = Mbit = MiB/8
You do realize that 100mbit is 100 MegaBits not MegaBytes
100 MegaBits = 12.5 MegaBytes
Look here: http://www.t1shopper.com/tools/calcu...cription.shtml
Generally my average upload/download on my network (100Mbit) is 5MiBps-8.5MiBps.

Dont mean you insult you but this is a common mistake.
oh hehe yeah I know what you're talking about :)Quote:

I still have to try that on the other comp though ha
what the hell
I put both computers on 100 full-duplex. Transfer speeds are embaressingly low! it took 30 mins to transfer 60MB wth?! and no other programs on either comp were using the internet
I am going to shoot my computer, unless you guys want to give me some advice and save my computer from being shot :)
Could be bad hardware... try exchanging the network cards.
Power cycle your router...
Is the router/network cards showing 100mbit connection (some have different lights, show a different color when functioning at different speeds/duplex)
Is windows showing 100mbit connection?
Also what Operating system/Edition/service pack are you using?
Try connecting a cross over cable between the two computers to eliminate the switch from the equation. If they are gigabit speeds, then it's more than likly the switch.
Use a gigabit crossover and you get lightning speeds :afrog:
You said the internet there. Are they therfore connected to a router that they then connect to the internet with. The router is a 10MBit is it? :)
Any normal Cat-5 crossover cable should do the job I thought, does for us at school.Quote:
