72 Meter Ethernet Cable Not Working?
Nov 14, 2011
I am trying to connect a pc with a cable modem using a cat5 UTP cable.I initially checked all the wires of the cable with a meter and then punched the RJ45 connectors to both ends and also checked them with a cable testing device and the straight through mappings were correct, but when i connect the two ends to the cable modem the respective lights do not show up. I have not tried the wire from the pc to the cable modem yet. The cable length is 72 meters.

as we know twisted pair cat 5 has maximum length 100 meter?
is because the voltage will decrease"weak" at the receiver "because the resistance of cable"? or because the noise will increase?

I have two ethernet cables, a long one and a short one. The short one works fine, but the long one does not work with my computer. It has worked with other laptops, so I am fairly sure the cable itself is fine - is there anything I can do

Daughter is at college with brand new Vostro 3450. Was working on school network during summer but drops the connection multiple times during the day. She runs the Troubleshooting which then allows her to connect and 30 minutes later the connection is dropped again. The laptop works fine when connected to the internet via the ethernet cable. Here is what has been done by the IT support at the school.
1 - Deleted the Intel wireless utility as they thought it was "fighting" with the Windows software for control over the wireless.
2 - Increased the power for the wireless card to "high performance".
3 - Reinstalled Windows 7 to eliminate that there is a software issue.
4 - Replaced the Intel Wireless Card with new part sent by Dell.
Now the IT supports recommendation is to "get a new system" and that perhaps the Vostro's wireless card is "not compatible with their network". For Dell computers they sell the Latitude to the students.
My daugther likes the Vostro. She doesn't want to give it up. Wants the system to work. She had the laptop during the summer session and had problems with connection. The Windows software was reinstalled thinking there was a virus (although no evidence of one) and then she had no connection problems for the whole summer. She came home for 2 weeks and returned back to school and then the system would not work again.
I don't know what to do. Can I buy a USB wireless adapter for her to temporarily use until I can figure out how to fix this problem. Personally, I think there is a design flaw with the vostro.

Is there a difference in an ethernet cable and an Ethernet networking cable? I have an Ethernet cable and a 6 port splitter I am trying to connect. I have 4 ports in the router that are in use. When I connect them to the splitter nothing s working.

I am having a problem with my Realtek RTL8168D/8111D PCI-E Gigabit Ethernet NIC. It is not detecting my ethernet cable, and thus leaving me without internet on my desktop, after i updated its driver. The cable is not the problem as I have tested the cable with my laptop. I tried rolling back drivers, doing system restore and removing drivers with driversweeper and letting windows install the drivers again. However, none of these worked for me. I doubt the NIC is faulty as it was working before i updated the drivers. I am using windows 7 home premium 64-bit.

I have a WAG160N wireless gateway . Yesterday when i tried to power it on after a couple of seconds the power led was solid green and the Ethernet leds were blinking with no Ethernet cable attached to the router . The ethernet leds would keep blinking for minutes . I tried to use a screwdriver to do a hardware reset ( with power on ) and i noticed that the power led would start blinking green/red for minutes . I tried to use another wired router which i have for backup and it could connect to the internet normally without a problem.
What the green / red blinking power led means ( power led is green and then changes to red and then it starts over ) ?

I have a Dell XPS M1530 with Vista 32 bit. When i plug in a cable i get nothing, no error, and the comp does not recognize that a cable has been plugged in. I think that this started after my Hard drive failed and Dell replaced it but i'm not positive. No errors (? or !) in Device Manager and I can't find the Marvell 88E80XX 10/100 Ethernet Controller in device manager. I have attempted to Reinstall the drivers. The wireless is still working. I have one Light to the right of the port that is on all the time solid but no flashing with the cable in or out.

I configured my RV120W (Firmware:1.0.2.6) to count the traffic on my network. I set the monthly limit to 99999 and did not change anything else.So after a few hours, the traffic counter shows 2048 MB for outgoing traffic. This is impossible, because the DSL-connection is too limited in upload to cause this huge outgoing traffic in 6-8 hours. When I reset the counter at night, the next morning the device shows 2048MB again (even if there was no traffic at all, just some clients syncing time with NTP). I did already reset the device to factory defaults and reconfigured everything from scratch.

I am working w/ WNDR3700, and I've been trying to take a look at the traffic meter to judge how much I actually us.
In 7 days I supposedly already used 30gig. There are only two computers to the network and the most we do is Pandora/gaming. Is this router incorrectly reading incoming/outgoing data? Is there someone logging into my router and downloading freaking porn or something? Because whenever I check to see connected devices, I only see our comps, are they able to hide their device on the router?

I would love to see this added in a future firmware release. I imagine others would welcome it as well that have caps with their isp.

When WAN traffic meter is enable on RV180 router maximum throughput drops to 40Mbps from ~120Mbps.Enabling WAN traffic meter is needed to get SNMP data from WAN port.

I'm trying to set up a system where a lecturer can sit at home and give his (video and audio) class across the street via an ethernet cable strung across the street. The only problem is he has a mac, and we in the class running it aren't going to leave our PCs for macs!Is there any simple way to connect the mac to PC (without running through a router, as it slows down the system)?If so, what programs will work best for both PC and mac for streaming the video (and are free)[BTW I don't think a 100m cable is too long for the signal.

Yesterday I was on my computer when all of the sudden my internet stopped working. I am using windows 7 and at the bottom right I see a big "X" over the small computer icon. I already tried a computer reboot, a router+modem reboot, system restore, and I even reset the power to the room of the modem+router from the fuse box in my house. I tried everything.
I'm sure the problem must be from the actual cable or mother board itself. ( I hope it isn't ) I tried blowing out any dust from the ports and making sure that nothing was blocking the connection. I fell asleep last night with the internet not working, and woke up to it working. Every other computer in my house works except for mine. I tried all of the router ports as well. I did not attempt another ethernet cable though because my room is far and I would need to make a very long one.

I just reinstalled Windows 7 on my computer again and appear to be having trouble connecting to the internet with my ethernet cable. I've only ever used a wired connection on this computer, but am completely unable to do so at the moment.

An older post on this forum told me to remove the adapter's driver software and restart the system. I did this, and it tried to install the software on startup but it keeps failing when installing. Forcing it to look for new driver software resulted in it saying the best software is already installed.

I am trying to connect my two laptops with one Ethernet cable without any internet to a Network. However, just one of the laptops is identifying the connection, the other doesn't recognize that it has been connected to another laptop. Obviously, the cable itself is working (because one laptop identifies the connection), but what might be the problem that the other laptop doesn't recognize any connections?

I'm trying to connect to the internet via the ethernet cable available in my office at the university but it won't work. I'm able to see other computers connected to the network, share printers and have access to shared files but have no internet access. I know that the problem is not the cable or socket because my old XP computer connects to the internet just fine.
I had a similar problem back at home but I just restarted the modem and was able to connect.
Setup:
Lenovo x220 tablet
Network card: Intel 82579LM Gigabit Network Connection

So I am trying to connect my desktop to my router via an Ethernet cable. When I plug the cable to my PC, it won't connect to my router. However when I plugged the cable to a laptop, it worked fine. I also went to check the Broadcom NetLink Gigabit Ethernet adapter in Device Manager and it has an error that says "This device is not working properly because Windows cannot load the drivers required for this device

My onboard adapter wasn't working so I bought a new dlink adapter. Adapter installed and is registering in device manager.. but it says that there is no ethernet cable connected. I have a laptop connected to the same router that is connecting to the internet. I switched out cables with ones that worked with the laptop and on the desktop before. I have cycled the router

I'm having trouble with my ethernet port. I have a Asus g73jh computer running 64-bit windows 7 and i have an atheros ar8131 pci-e gigabit ethernet controller NDIS 6.20 for my network adaptor, that is fully updated and says is working properly but doesn't recognize when an ethernet cable is plugged in. The cable works on my xbox fine so I know that the cable works fine. I'm pretty sure that there might be something physically wrong with it or I just don't know.

At the moment I cant run an ethernet cable through my house from my router to my desktop PC (Which is where I use the internet/play games etc) and connect directly that way because my parents dont want cables going through the house etc etc.For the past 2 months or more I used my old laptop to pick up the wireless connection downstairs then I bridged the connection and used my ethernet cable from the laptop into my PC/Xbox or whatever, no problems until today, I wouldnt even have to log into the laptop, i would just turn it on and leave it at the login screen and I would have internet on my desktop/Xbox.Tried to do that today and was getting unidentified network on my desktop, i dont know what the problem is, I can connect directly to my router with the ethernet (I tried it) but not the old way anymore, i'm on the laptop now on the wireless internet.In network connections there LAN network isnt there anymore, its just the 'Unidentified Network' which is the bridged connection.
