Ethernet Working But No Packets Getting Sent?
Feb 1, 2012
Basically a while ago last year some time in December my desktop got turned on one day and the internet wasn't working. I tried using my wireless to connect but even that was stuck on "acquiring network address". Ive played around with it abit since then and now my etherent cord shows up as connected but when I go into properties it says no packets getting sent / received. In device manager all my network adapters are cool and dont have any "!" next to them.Ive also tried the cord in my laptop and it works cool.

i'm trying to connect a picaxe microcontroller to my friend's coffee machine for a school projet. eventually i realised i had 4 options
1:get arrested by the police (long story)
2:lay out 5km of cable dorchester,dorset,uk
3:end up using a REAL pickaxe on my phone
4:pay £100 for a picaxe server
5:intergrate the ethernet into a picaxe microcontroller
the only problem is that you need a very fast processing speed for ethernet,unless you were to use <1mbs ethernet?is there a device witch will only relay packets at <1mbs Ethernet

I have a DLink DIR-615 rev. B2 firmware 2.25. A few days ago, I started using Comodo Unite for VPN access with friends and LAN gaming. However, just recently the program stopped working correctly. I have reset my configuration, tried multiple different settings, and nothing at all has remotely worked.

I have a switch that I have configured for jumbo packets, but they don't seem to be functioning. I have set system mtu jumbo 9000. The hosts are connected via 2x EtherChannel links. The hosts are jumbo frame enabled, and can ping their own local address using jumbo packets & do-not-fragment flags on the pings. They cannot, however, ping each other or the switch that way - it always says that the packet requires fragmentation. I know the attached machines (they're all VMs) and virtual switches support jumbos because I can ping within the virtual interfaces of the VMs. It's just traffic that goes over the switch that fragments.The switch is a WS-2960G-48TC. Here are the various outputs, with a section of config at the end.
hrnacancwtdevs3#show system mtu
System MTU size is 1500 bytes
System Jumbo MTU size is 9000 bytes
System Alternate MTU size is 1500 bytes
Routing MTU size is 1500 bytes

I recently installed DHCP snooping on a 3750v2 switch (Version 12.2(55)SE4) and configured the uplink(Po2) as a trusted port. The problem is that clients cannot receive an IP address. When I disable DHCP snooping it is working properly. DHCP snooping is configured correctly but I don't have an idea how to resolve it. [code]I tested the solution on the same kind of hardware switch and firmware and it worked out fine. What is causing the clients not to receive an IP address from the DHCP server?

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

Ive been using my Sony Vaio laptop (windows 7) to connect to my uni halls internet connection by ethernet cable (and keysurf login) for months with no problems, now all of a sudden my ethernet cable is not being recognised. its not a problem with my connection or cable as other people's laptops work on it. and its not a problem with my hardware as my laptop works in other people's rooms. its just the combination of my laptop and my connection. My friend did something along the lines of resetting the IP address, but not really sure what he did. So i've done a full recovery of my computer.

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.

I recently installed Arkham City on my computer played it for a while, tried google chrome, gave me a corrupt profile error or something (internet still worked and was connected at the time) restarted my computer and now it's telling me there isn't an ethernet cable connected to my computer.
Here's what I tried so far:
-Uninstalling and reinstalling the driver
-Updating the driver
-Using the network troubleshooting for windows 7
-Doing a system restore before I installed the game (gave me an error saying could not complete restore)
-Currently scanning my computer in safe mode with networking (seeing if that might work, doesn't) with malewarebytes
-Unplugged and replugged the router and modem
-Checked the router on another computer to see if there's a connection (there is none)
-Checked the router to see if there is a light in the port connected to the ethernet, it's blinking at a very slow a steady pace, unlike the ones around it which are solid green lights
-Tried the ethernet cable on another computer, works fine.
computer specs:
Windows 7 64-bit home premium edition
Gigabyte GA-MA790X-UD4P
NETGEAR router WNDR3700

The other night we had a thunderstorm. It kicked me off the internet. Now, I can connect directly to my computer to my laptop (wired), but when I try and establish the connection between the Cable Modem and the Router...it will show a connection between my PC and my netgear WND3400, but not between the router and the cable modem. Also, the ethernet port on router does not light up when connected to modem.

I was having a cleanup of the desk and unplugged the cable shortly, and after plugging it back in it could no longer find any connection. The only way I seem to be able to get connected to the internet now is to run a cable to my ethernet switch, and then onwards to my computer itself. Even when doing this the net seems to be very slow, won't connect through Chrome etc or just flat out won't connect.

So I have an HP Pavilion dv9000 laptop with window 8 installed and when I try to connect to the internet I keep getting an error that says the "Ethernet" Adapter is not working properly. I used to be able to go on the internet and then my dad had my computer for a while and now it's not working.

My computer is a Dell Inspiron with Windows 7 Home Premium Service Pack 1. A few weeks ago, it stopped working and would not let me log in. I fixed that problem by launching Setup and downloading the Windows 7 installation from a jump drive. The new problem is that I cannot connect to the internet at all. My wireless connections will not show up and when I hook up my ethernet cord, it will not show up either.

I get the message "unidentified network - no internet access" on my computer since my upgrade to Windows 8. I'm using an Actiontec GT704-WG DSL modem/router connected to an ASUS M4A79XTD-EVO motherboard. I can get wireless access to my computer - a desktop - from the modem but not from the cabled DSL. Wireless is slower and less reliable it seems

I have an ASUS X58C laptop which has been working OK to the internet via the ethernet cable but it has stopped working.I used the laptop via the wireless connection to access the internet while away from home and on my return I can not connect via the ethernet but I can connect OK via wireless. The results with the wireless enabled are :
C:>ipconfig
Windows IP Configuration
Ethernet adapter Local Area Connection* 13:
Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :
[code]....
I can see that the ethernet adapter(s) are shown as media disconnected but I don't understand how to make them connected. I also don't understand why there are two ethernet adapters or what the Tunnel Adapters are.Before I did the ipconfig command I went into Control Panel/Device Manager/Network Adapters/SiS Ethernet Controller, right clicked and selected the Update Driver Software which searched the internet for a driver and installed it.

I live in a frat and I am currently researching how to design and configure the most efficient network for the house. However, one of the other big problems we have is connectivity of our ethernet cables. We have an IT room with 2 switches that feed ethernet cables to all parts of the house and connect to an ethernet box in the wall where we can simply wire in our internet connection. We have wireless routers too but to keep the bandwidth usage across the WAP's I want to let people use the wired connections. However, many of the connection in the house do not work at all. I plug in my laptop to the wall jack and it gives me the No Internet Access notice. I don't understand why it works in some rooms and not others. All jacks seem to go into the same switches at the other end so I cannot figure out what the problem could be.

My pc is windows xp an has service pack 3, the adaptor is realtek RTL8168/8111 PCI-E Gigabit Ethernet NIC. I have 3 gig of memory and a very larg nvidia card. OK my pc has worked absolutely fine until this weekend when my sister came and her son was on my pc when everyone was in bed. He attempted to print of not less than 88!! pictures he had acquired from different sites but i had disconnected the printer so it didnt take place. When they left earlier today i switched on my pc and there was a virus alert so i ran a scan. These got put into the chest. I then attemtpted to close down the programmes that had come back up when i switched on and this is when it happened. The pc told me it was going to shut down and when it restarted i had not internet connection. I checked the modem and the ethernet light is out.

I've been having some problems with my Ethernet connection lately.I unplugged my laptop from the Ethernet connection I had at my old place.At two different locales, I have tried to use an Ethernet connection in order to get better speed (the wireless at the first locale was non-existent and at the second it is extremely slow in my room). I have done so with two separate cables that I have tested on others' computers and found that they are perfectly fine. That, of course, leads me to believe that it is my computer and is either a hardware or software problem (here's hoping it's the latter).Anyway, my laptop is a Dell Inspiron 1720 (purchased in 2006). About a year ago, I updated to Windows 7 from the pre-installed Vista. Never had any problems (as I said, everything was fine up until about a week ago). The installed card is a Broadcom 440x 10/100 Integrated Controller. Everything under Device Manager indicates that the hardware is working properly and has all of its drivers installed, but nothing is working.I have tried to uninstall and re-install the drivers (albeit by allowing windows to find them automatically), but the result is the exact same.I have checked the port and found that there is no debris or obstructions. My computer hasn't been dropped or mishandled in any way.I'm currently being housed on the campus of Delta State University, which is why this appears, but here is the report: [code]

It's a Dell Inspiron N4050, running Windows 7 Home Basic, Service Pack 1. I haven't been able to connect to the internet via an ethernet cable nor wirelessly. The wireless indicator is on (duh!) and the ethernet cable works with a PC sitting next to the laptop. I have a ARRIS modem (yes, the third world) and it works fine wirelessly with other devices here such as phones and laptops. When I plug in the ethernet cable it tells me that it can't identify the network. I do see all the wireless connections but it's the same, unable to identify network. I've tired all sorts of things, having studied computer science myself I'm not a total beginner, but the OS is in Spanish so it's really hard to make sense of things. If I can't fix this soon I will be forced to reformat the computer. The pros of doing that is that I will get the OS in English and lose all the rubbish Dell pre-installs on their products. The setback is that I won't have the drivers installed for the NIC and other things (although they should be on the optical disc that came with the notebook). Perhaps the problem is the modem, maybe I need a driver for it. Somehow I don't think that is the case because I brough my own hard drive from my country of origin and I put it inside the PC and it connected instantly with the internet via the modem.
ipconfig:
IPv4: 169.254.113.41 (link-local address)
Subnet mask: 255.255.0.0
Default gateway: none

When my desktop is online via Ethernet, wi-fi stops working. A signal is detected, but is very unstable and often doesn't connect to the Internet at all, on any device. As soon as the desktop is no longer trying to access the Internet, all other wireless connections work without a problem. Base computer is Windows Vista Home Premium with all latest updates installed.Other connections include 2 laptops (one Win7, one PCLinuxOS), 2 Kindle Fire, Wii, iPod Touch, four cell phones, and Sony Media Player. They're never running all at once. But any number of them can run fine-- as long as the desktop isn't online at the time.
