In this type of situation their might be something wrong with our Lan card. What is a LAN card and how much should we know about it?
How to check whether Lan card is working or not?
If you have more than one computer that needs to be connected to the Internet source, then a LAN card is the magic wand! As large scale business industries or universities, etc uses Wired Network Topologies system. It is a group of computers and the associated devices which are connected to a common shared network line or Wi-Fi.
Some common advantages of the LAN are:. This model, or way of explaining networks, includes seven layers.
The first two layers are the physical layer and the data link. Each layer of the OSI model allows for other layers to be independent. Upgrading or changing one layer does not affect the others. Nothing more mind boggling really! Looking at the products available in the market today, the original LAN card has been superseded and now all we have is the LAN port which has been installed in the motherboard itself.
Follow the steps to see which network interface you are using:. A trouble in any one of the computers that are connected to the LAN could cripple the whole network. So if you have set up a LAN then you should be able to troubleshoot some of the normal issue that may come up before you impulsively call the Network Admin.
Another issue could be some network drops in the services provided by the network provider itself. This would again disable any functioning of the LAN.
So any issue with the server itself, is translated as the issue of the entire network. With the development of technology, the wireless type LAN local area network is now mostly preferred. Installation of the driver is a one-time process and most of the issues that may crop up in the seamless use are related to the corruption of the drivers.
For most of the devices you can download the free driver here. Trouble shooting the above issues is as simple as re-installing the driver.Used com tct launcher
You should always check the cables and connections to ascertain the absence of any loose cabling connections as well. If the network still has issues then you need to change the LAN card. It can be damaged with prolonged use. Many times everything seems to be okay with the internal connections and the drivers, yet the connection to the network fails. If your computer is not connected on the network, youcan easily blame the LAN card for it.
But surprisingly this issue can be caused due to many other problems also. To identify what could be causing this here are a few steps to be followed. For this go to the device manager to check the status of your LAN card Driver.
If you are using a Windows Xp, 7, Vista or 8 then follow these steps:. This will help you with many options of diagnosing the problems and then troubleshooting them in both the Operating systems.
Note: If this entire self-troubleshooting module does not work, that means there is some problem with your LAN Card. Sadly, you might have to replace it! What it actually does it ruins the software settings and components of the card and make it useless.
So if Malware is the culprit you should not have the need to replace the Card as such. Then this would immediately send a rush of power which was being consumed by the printer to the other devices. Use portable Surge detectors to save your devices. These are devices which are built to absorb the power surges in the network and have lights to detect the power surge.I've tried all the ports with the same cables and with the laptop and ps4. One thing you have not looked at is the possibility of a circuit problem.
Please go into your hub on When it does cut out again ill send the updated log. Your hub is losing lock to VM's network. Check that all cable connections are tight. If they are you need a technician's visit. Ethernet stayed active for a whole day before cutting out again this time but not even keeping connection for longer than a minute since.

Network Engineering Stack Exchange is a question and answer site for network engineers. It only takes a minute to sign up. I have a small and inexpensive ethernet switch which is giving me some headache.
For some reason some devices only work when I plug them into specific ports. The ports are not broken, as other devices work on the same ports. Also, if I just take the cable from one of the ports that doesn't work and plug it into another port, it works fine. I also tried to restart the switch, computer, flush ARP cache etc. They reason why I am asking is because soon I will undergo a massive operation where we have to connect hundreds of these devices to the network, and we plan to buy 48 port switches for this purpose.
If they start playing strange games like this, I am absolutely unsure what is going on. Could this be a problem with the switch, is this expected, or do you believe it is rather a computer problem or router problem the switch is connected to a routerbut I am not using a gateway on these devices or the computer and as said, as soon as I plugin the devices on a different port, they start working.
Just because some devices will link doesn't mean the switch isn't still bad. Personal example I have a Nortel ERS with a damaged clock circuit power outage killed it. I've verified with a scope that the clock for the second half of the switch is noisy and marginally out of spec. As a result, some network cards will link, and actually function.
However, most, including the other half of the switch and every other switch I have, won't. Cheap switches are cheap for a reason. This means that the switch cannot detect the difference between crossover or straight-trough wiring and cannot adjust to the current wiring situation. The most common setup that I've seen is switches with some of each.
I've also seen some switches that have a hardware toggle to change the wiring scheme of a port. What I would suggest is to experiment with crossover and straight-through cables and see if that fixes the issue for those ports.Free smtp server
In the long term, inexpensive consumer hardware is just not equipped to deal with many use cases and you may want to look into upgrading as some commenters suggested. The most likely issue is the cables you're using. Some cable connectors are rather short and some ports are rather deep, so when these two come together they don't link - or rather, they link only when the connector is pushed deep into the port and held that way.

Thank you. Go to Solution. I downloaded and installed that driver. It did not solve the problem. Install said it was already on computer and did I want to overwrite it. I said yes to all. When I click on Network and Internet settings from the wireless icon in lower right corner this is what I get. Thanks again for any assistance you can offer. That can often wreck the internal ethernet chip and there is no way to fix it other than to replace the motherboard.
I recommend that you purchase an external USB to RJ gigabit ethernet adapter to restore the ethernet connection. That is probably the issue. We have had thunderstorms unfortunately no rain here, but other places, VERY dry.
One was closer and it apparently took out our router. They replaced it earlier this week. I guess the two happened at the same time. I would guess their fiber optic cable coming into the house had the surge. Luckily our battery back up protected the computer. Would a surge account for the fact that the desktop starts up now when I start up the surge protector in the morning? If the lighting took out the router and they had to replace it, then it definitely took out the onboard ethernet chip.
If you leave the surge protector on and shut down the PC, do you have to press the power button to turn it back on? There wasn't a power loss at all, except the router stopped working. It all happened on Sunday and we don't use the desktop on Sunday's typically so it was off. The surge protector was on for the router and we use WiFi for our Kindle tablets.
We shut off the surge protector at night along with shutting down the desktop and Kindles. I'll look into the BIOS and see if something changed. I'll also check the surge protector manager and see if something there changed - possible and hadn't thought of that until you mentioned the BIOS.

Last thursday lost power for about a hour. Lost internet in port 1 of arris modem, switched to the other port got back internet. Wireless works great, but the only ethernet port that lights up white is the one going to computer.
I have xbox and phillips hue connected both are orange and they flash on and off. I can switch ports and it remains the same only one white is computer and the other 2 orange. Wrong port-status LED indicator color, or some actual trouble?
Probably not. Get the User Manual. Look for. LED and button descriptions" and "Ethernet ports ". Further reading might also have some value. Gigabit network speed probably wouldn't improve the experience with your light bulbs.
No internetit would connect then say not connected. It has finally connected but I was not sure about lights thought they used to all be white if connected. Power cuts, if that is what you had, usually take out both the modem and the router in a network. When the power comes back on, they may start up in the wrong order, with the router starting before the modem is ready.
That means that they get confused about which is in charge and the router fails to connect to the internet. It may help to reboot the whole network in the right order. Be sure to restart your network in this sequence:. We are continuing to monitor the situation to ensure that the best possible service is provided to our customers.
