Weird Networking problem (Problem Fixed)

[BarnyardMonkey]

I tried all night last night to get another system of mine up and running through my SMC Barricade Router. (Cable connection)

the Router is the 4-Port Barricade and i had 3 PC's hooked to it till last night.
i tried to hook up the fourth and heres whats happening:


After install of the NIC in the 4th system (Intel 10/100 PCI),i was able to get an IP from DHCP on bootup.
it did load into windows quite slow though.

but when trying to browse the net,it just says "contacting site.........then finally waiting on website reply" then does nothing.goes to "page cannot be displayed".

and if i try to hit Release IP,then Renew... it will just hang and can't get IP. (winipcfg)


but i managed to see other PC's under network neighborhood once or twice,but it will hang when trying to access the other PC's files.

i did however manage to get connected on a LAN game on AOE2 with no problems. (only tested for about 5 mins)


but then if i try to renew IP it will hang then say it couldn't renew,and it still will hang when trying to access other PC's on LAN.

I thought maybe the prob was with my networking cable that i had fixed tonight (50' Cat5),but i tested it on one of the other PC's and it ran fine.

Also know that the NIC in the system is fine.i pulled it straight from my main PC to test it with.

Specs on non working system: (4th PC)

Compaq Presario 5000
Intel 10/100 PCI NIC
50' Cat5 ran into SMC Router (Cat5 was changed over from a Cross-Over cable last night)

Networking Settings:
Client for MS Networks
Intel NIC
TCP/IP
File print sharing (Ident name is different from other PC's)
IE is not set to Auto detect settings


Any help with this would be appreciated.i've never seen nothing like this, i'm lost.

if anymore info is needed just ask and i'll post.


Thanks.

I had a problem today that is similar ...

we moved the boss from his office on the same floor as us to one on the ground floor ...

i ran a new cat5 cable around 40 ft and it didnt work re-crimped the ends ran another cable and still nothing brought his laptop upstars and conneted it the hub it worked took it downstairs again and ran this realy long test cable i used for testing (the one that worked upstairs when testing the lappy) into his office and back to the hub ....

it worked ?????? why ??? the only thing i can think of is either damaged cable "yet i checked it with a circuit tester loopback test" or the length ???

but its working now with the old cable now this cable is about 2.5 years old go figure lol

maybe something like this is happening to you?????

On many of these routers, there;s an uplink port (basically a crossover), The Uplink port shares the same transceiver with the "normal" poort next to it: you can use one or the other, but not both at the same time. Check that you didn't use the "normal" port next to the uplink (if you're using yout uplink).

Otherwise, being the cable semi-oriented guy that I am, I'd swear at the cable & re-terminate.

Good Luck

I don't think it has anything to do with the Uplink port on this one.
i had another system downstairs hooked up fine with all 4 PC's together (25' cable).

Listen to this one now:

I decided to run the 50' cable straight into my Cable modem without Router.
and BAM!...first shot it works fine with no problems.
then i run it back into the Router and BAM!...nothing..hehe

tried different Ports on the Router,reset switches,etc etc....still nothing.

seems the cable is fine or it wouldn't have worked running straight to the cable modem,and also worked hooked into another system.


gonna try and run the 25' somehow and see how that goes.

this is crazy.

Ok there seems to be a problem with this 50' cable running on an 10/100 PCI NIC with the Router.i tried 2 different 10/100 NIC's and they both fail to connect when hooked to Router (only with the 50' cable),but run fine straight through on the cable modem.the 25' cables work fine with Router on all systems.
but the 50' will work fine on an old 10BT NIC with the Router.

But the system i need the 50' cable on has no ISA for the 10BT NIC...hehe

so it seems the guy did my cable wrong?

If you click on "Start", "Settings", "Control Panel" then double click on "Network" then find your network card in the box there, and click "Properties" then click on the "Advanced" tab, then click on "Media Type" in the box. You can then change the value (It is the drop down box on the left). It will give the option right there to limit your card to 10BT if you want to. Also Full or Half Duplex as well.

^That is for Win 9X and ME.... I'm pretty sure that you can do the same thing with NT, 2K, and XP. Not sure where though... If you dig, I'm sure you can find the settings for it.

Sounds almost like it is not auto-negotiating properly. I would try what Jonathan93 said and force 100Mbps and Full-Duplex. Do the other computers see the computer fine? Can they ping it without difficulty?

 

[Setral]

I agree with Jon and Muc, I bet if you set it down to 10 Half or 10 Full it will function properly. If so then your cable is not up to the 100Base T Spec. Either the 50 length is causing it or the cable itself is poorly made (no offense).

So here's the ifs.

If 10 Half works & 10 Full works but 100 Half or Full fail, your cable isn't up to 100Base Spec.
If 10 Half works but nothing else, your cable is crap and you need a new one.

Basically if it only works at 10 Half or Full but nothing else you need to either examine the cable or get a cable that is 100 Base spec.

Jonathan93, You was dead on man.
i went to the NIC settings and changed it to "10BT Full Duplex" and it started up with no problem. 🙂

Thanks alot for the help.i was narrowing it down,but couldn't seem to get it working with the 10/100 NIC's.

Thanks big time.


Setral, since i have it working on the 10BT Full Duplex setting,it will be allright running with this cable right?
even though it don't seem to be 10/100 compat?
