Maximum Lan cable length question

[zyberboy]

I need to connect my pc to a friends pc which is 75meters away,i have already bought the lan cable but its not working cheked with multimeter no problem with the lines or Rj-45 connecter,but network signal is not reaching the other end.
Hav anyone seen any lan network(using switch) which worked at this distance without any problem?.I have other two connections at 25meters which are working fine. The cable i used for both 25m & 75 meters is i-link which cost 7rs per meter. The guys at computer shop(and all other network junkies i asked) says even though max lan cable length is said as 100m it wont work above 55meters.Is it true?(they say it wont work even with d-link switch and cable).
I am read to buy D-link cable and D-link swich but will it work?,its not possible for me to put a repeater at the center becoz the cable is running above another house.

Edit: currently i am using intex 8 port switch

I can't exactly tell u the length of my cable but its quite long enough...
Try these
* Check the twisted pairs are they properly done... The order in which they are made specifies whether it cancels each other.

* Next make sure no sharp bends are there.

* If not working on 100 mbps try at 10 mbps mannually.

* Try with a different NIC, it sometimes solves the problem.

Generally the length limit of the LAN cable is there. The maximum limit always vary. I suggest u to go for a Cat6 D Link cable for this LAN configuration.

a switch would definitely do the joB! in my school, we have comp in every class.. and it is all connected to a main server 120m( apporx) away.. they use a switch.. it works perfectly fine..

^^but they may be using switches which are not easily available in local market isn't?

Why don't u go for a Wireless setup? I mean wireless PCI card will cost almost 1200/-

[zyberboy]

^but wireless router wont cover that much distance.

How much of distance is covered by PCI wireless card????????

CAT6 will cost u arround 12RS per meter. it's only the estimate price.
