Does anyone knows how far apart I can have one computers connected from
Cable/DSL router. I know that I can get 100 feet JR45 Cat 5 Ethernet
cable or more. But what is the maximum distance I can use without buying
any additional equipment such as repeaters.

Thank you

Cat5 has a max distance of 100m.

so what if you got the best quality cable you can buy...i mean the stuff you
cant get in the shops..........and then extended

your network to 500 metres??

i add this comment because i was told my usb would lose some of its
"strength" for want if a better word if i started using extensions over 5
metres....

bolony i thought so i did some tests.....

i found out i could easily extend usb 1 or usb 2 to at least 50 metres with
no noticable data loss.........i didnt go any further than that.....

so i reckon the distance they give you for lans and the like are just
guidelines.....and if the cabl is real good,,,there should be minimal loss
over any distance......

at the moment my lan 's longest cable is 30 metres......(goes to next
door )....

and there isno loss at all....

just thought i would comment...

regards slayer

would be interesting to get more comments on local lans ??

The USB cable is different, as it is a direct connection between the machine
and the device. Typically ethernet (aka your standard cat5 cabling) is used
to connect multiple devices. The problem here is that if the machine is too
far from the next device in distance then they can transmit without the
other knowing it has transmitted. This causes collisions on the network,
which although can be possibly recovered via the TCP protocol, isn't the
best set-up.

If you run machine to machine via full-duplex this is different as the
machines can send/receive at the same time. Also you can extend over 100m,
but if you need to run over 100m on a local network with multiple machines
then you need a hub/switch/router in the middle to buffer and retransmit the
signal to avoid collisions.

Hope that made sense as I've just had a few beers ;)

I thought that full-duplex mode is used when two computers are connected
with a crossover cable. When a computer is on a LAN connected through a
router, half-duplex should be used??

I've got my NICs on Auto, anyway.

That's the way it works here. Router is 1/2dupe and if I use the crossover
with my laptop to desktop XP just does it's thing and sets it up full dupe.
I use XP Pro, so don't know if Home is the same or not. Never used it. The
router will take care of packet management so it is really acting like full
dupe anyway. I just use whatever XP does. Simple as hell. I had to transfer
some files from my desktop to my laptop one time and couldn't find the
crossover cable, so decided to try firewire....:-). Hell, XP even set that
up and it worked........

ive heard firewire is a fast connection......

but my lan is basically 4 machines and a hub.....

one on a cross over cable.......(on uplink on hub)

maybe ill go wireless next......i got hold of some cable to connect the pcs
,,, was told it was shit hot and extremeley expensive......will easy connect
over 300 metres,,,,,

ill put it in the cupboard with the rest of the "to use one day stuff "
