I have a network in my house, and i have run in to problems.... most dealing with distances.

I have a Netgear RT314 router.

I have PC's connected to all ports on the router. But i have a problem.

One of the cables that comes out of the router, i need to hook a hub to....

now that cable is about 60-75 feet. The Cable works fine alone..... but if i hook a hub to the end of it and connect the PC's i cant get internet or communicate with the router. I was told that the length of the cable is the problem.
most of the wires are cat5 and cat5e

ive ordered cat 6 cable and im hoping that will work...... so can anyone tell me whats up and why my hub wont work?

I believe your problem is, that you need to plug the cable from the router into the "uplink" port on the hub.

Look for a port marked, uplink, If you don't have an uplink port, then you'll need a crossover cable.

I have the same setup with an NG rt314 and a Linksys 4port switch and works fine.
Also, remember that when you use that uplink port on your hub, you cannot use the port ajacent to it. They are sort of tied in together.

Good luck !

VonJames is correct, you need a crossover cable (for non-uplink port to non-uplink port) or regular cable (for non-uplink port to uplink port). Also, cat5 is good up to 328 feet (100 meters).

thank you for the reply... but thats not my problem..... the hub works fine when its close to the router..... about 10-15 feet.......

i was told a switch might work for my situation though.......

plus..... i had a linksys router to try for a few days..... and well the uplink port on the linksys was only to go to another hub the manual said..... and the wan port was to hook the cable in from the router..... but anyway thats besides the point.....

but yeah, i did plug it in properly... the hub....... and after that, i did try all the ports in every combination to be sure.....

uplink port on the linksys

You want to uplink the hub to a LAN port on the router.

the hub works fine when its close to the router

The longer cable may be bad - but as was stated 328ft is the limit.

Hmm...
Since you've tried all cable combinations without success, could be the hub is bad.

Though, I'd wait to hear another opinion from the experts here.

yeah, i tired a hub, that i use here at my school and also a new hub i have at home..... im wondering if a switch will work......

I would check the Duplex settings for the network card. Set it for Auto-Negotiate. If it doesn't have Auto-Negotiate, set it to Full Duplex if it's plugged into a switch and Half-Duplex if it's plugged into a hub.

monkeyhead · Post by **monkeyhead** » Sun Mar 17, 2002 11:50 pm

well........ before i even ending up needing a hub/switch in my home network...... i had a crap load of problems trying to set it up..... any computer far from the router had to be set to 10 mb/sec...... if it was set to 100... it would not work.

Also when i insert the Hub into the network..... i cannot telnet back to the router either.....

i havent really done much with duplex settings, all the computers on the network are set to 10 and half duplex.....

the easiest solution to my problems is getting another cable modem..... but the money is not there for that..... and that is why we bought the router so we wouldnt have to do this

keep the information coming though, all and any of it is appreciated.... and thank you

Cat5 can be used in 'ideal' situations up to 330' then fibre is recommened. Check your RJ-45 connectors and make sure a pin or two hasn't been bent. Just a suggestion.

Had the same bloody problem with my Linky. Auto-Negotiate baby!

ive got some more information now that i think about it...... length is not a problem when not using a hub...... about 125 feet was the longest tested and that worked fine...... i wont need it to be that long.... but it was fine.........

but...... if i hook a hub up anywhere about after 60 feet or so..... the hub does not work.....

That's the strangest thing. If you lan tested the cat5 cable and it tested fine it leads me to believe there is a configuration issue with the router/hub. I'm leaning to hardware maybe the hub but check to make sure the hub is connected to the lan port of the router. Also, are you using a straight through patch or a rollover cable to connect from the router to the hub?

monkeyhead · Post by **monkeyhead** » Mon Mar 18, 2002 12:11 am

it is a straight thru.... i do believe....

Try a rollover cable. If you need a hand with the pin outs and termination of the RJ-45's don't hesitate to ask me.

monkeyhead · Post by **monkeyhead** » Mon Mar 18, 2002 12:18 am

well i have found this link..... so you say i should make one a crossover

http://www.homenethelp.com/web/explain/ ... ssover.asp

and this crossover will be about 60-75 feet long... that is ok too right?

That is your problem more than likely.

switch to switch can run full duplex, 10 or 100 meg depending on hardware.

switch to hub - half duplex

pc to switch - full duplex

pc to hub - half duplex

It seems like your hardware is good, but your configuration is wrong.

Go with what Roundeye stated above. That is true. If that does not seem to work...try the crossover cable. Your cable length is just fine

Joint Chiefs of Staff · Mon Mar 18, 2002 11:33 pm

Haven't heard from you today. How goes the router/hub situation?

monkeyhead · Post by **monkeyhead** » Mon Mar 18, 2002 11:50 pm

damn, u is awesome Joints...... i thank you very much for your consideration... but the problem awaits me at my house.... while im here at school..... i should be going home wednesday to install a motherboard and put my server back up..... thats when i will get to try all the ideas you guys have given me.... so until then..... i cant do much but wait

Joint Chiefs of Staff · Tue Mar 19, 2002 9:58 am

I expect a post or PM with the results, don't leave me hanging bro. LOL I'm curious what the problem is myself.

monkeyhead · Post by **monkeyhead** » Tue Mar 19, 2002 10:08 am

dont worry, i will be sure to inform you of the results.... and im sure some other problem will arise..... thats just the way my luck goes

monkeyhead · Post by **monkeyhead** » Wed Mar 20, 2002 6:50 pm

the cat 6 did it.....

thank you everyone for replies....

Joint Chiefs of Staff · Wed Mar 20, 2002 10:14 pm

So what your telling me is you upgraded to cat6 from cat5 and your problem was fixed?

Hmm. That doesn't make much sense. I wonder why that solved the problem...

VonJames · Post by **VonJames** » Wed Mar 20, 2002 11:17 pm

I'm no network guru or anything, but that just doesn't make sense to me ...
But, I would be interested to know the technical answer.

Good to hear you got it going though.

monkeyhead · Post by **monkeyhead** » Thu Mar 21, 2002 1:01 am

actually to make matters worse...... it was cat5e wire that i upgraded from....... so, yeah it really bothers me....... now the only other thing i can think of though is this......

the cat6 wire that i tested runs from my router out my door, down a flight of stairs, then down another flight of stairs to the hub...... while the cat5e wire is run thru the walls....

my point being.... ive heard that well some types of insulation or other cable wires or electric wires etc can cause interference...... now im not sure to what degree or if this is even true...... so the true test comes when i run it thru the walls...... but i think that everything will be ok anyway.......

and thank you again people for the replies and help

That makes more sense b/c cat6 is designed to cut down on interference to support greater network speeds. Thus, I guess your cat5e run could be suffering from interference.
