Network Problems (Solved)!




01. Ethernet Cable is Unplugged or Not Plugged Properly



Total Solution :

Restart the computer by fully powering down, waiting a few seconds, and then turning the computer back on. If you're on a laptop, take the extra step of removing the battery, if possible, and walking away for 10 minutes. Just unplug the laptop from power and remove the battery. When you get back, reattach the battery, plug the laptop back in, and start Windows again.
Disable the Ethernet network adapter if you are not using it. This applies, for example, when running a Wi-Fi network with computers that have built-in Ethernet adapters. To disable the adapter, double-click the small "A network cable is unplugged." error window and choose the Disable option.
Check both ends of the Ethernet cable to ensure that they are not loose. One end is connected to your computer, and the other is connected to the main network device, probably a router. If this doesn't help, try testing for a faulty cable. Instead of buying a new one outright, plug the same cable into a different computer or temporarily swap out the Ethernet cable for a known good one.

Update the network adapter driver software to a newer version if one is available. If it's already running the latest version, consider uninstalling and reinstalling the driver or rolling the driver back to a previous version. It might seem impossible to check the internet for outdated network drivers when the network can't reach the internet. However, some free driver updater tools such as Driver Talent for Network Card and Driver Identifier can do just that.
Use Device Manager or Network and Sharing Center (via Control Panel) to change the Ethernet adapters Duplex settings to use a "Half Duplex" or "Full Duplex" option instead of the default Auto selection. This change can work around the technical limitations of the adapter by changing the speed and timing at which it operates. Some users have reported having more success with the Half Duplex option, but note that this setting lowers the maximum total data rate that the device can support. To get to this setting for your network adapter, go to the device's properties and find the Speed & Duplex setting within the Advanced tab.
On some older computers, the Ethernet adapter is a removable USB dongle, PCMCIA, or PCI Ethernet card. Remove and reinsert the adapter hardware to verify that it's connected properly. If that doesn't help, try replacing the adapter, if possible.
If none of the above procedures fix the "A network cable is unplugged" error, it's possible that the device on the other end of the Ethernet connection, such as a broadband router, is the one malfunctioning. Troubleshoot these devices as needed.

02. Network Path Cannot Found

Total Solution :
 "error code 0x80070035 network path was not found" on Windows Vista and Windows 7 Computers. Click on the "START" button, select "CONTROL PANEL", and go into "DEVICE MANAGER". Click on "NETWORK ADAPTERS", then click on "VIEW", and select "SHOW HIDDEN DEVICES". In the expanded view you will see a long list of numbered "MICROSOFT 6to4 ADAPTER". My Windows 7 Professional desktop had 200 of them. Right click and select "DELETE" on all but 1 of them. You can only do 1 at a time so it does take a while. When you have only 1 left, restart computer and enjoy being able to see your other network computers, including HOMEGROUP files.

netsh int ip reset

Resets TCP/IP on Windows 8 and Windows 8.1. Rebooting the operating system after issuing this command returns Windows to a clean state.

03. Connected With Limited Access

Main Solution :
The problem (Limited access , sometimes it said no internet Conn.) was solved by removing IpV6 attributes, its pretty common if your Wi-Fi is highly secure, as in my college. Follow these steps
First get connected to wifi
Go to Start->type network and sharing centre ->click on it to open a window which shows the network you are currently connected to->click on the wifi name shown (SSID) -> click on properties -> scroll down to IpV6 and uncheck (deselect it) no need to click on it, just uncheck the check box ->click on IpV4 and a new window appears -> make sure that IP address is set to automatically granted-> click OK-> click OK .
Problem solved no need to disconnect or restart. Just start browsing after the last OK click.


04. Slow Network or Network Speed

Main Solution:
Make sure that all the peripherals are connected and working properly. Use file compression technologies to reduce the burden of bulky files on network. Find and analyze the users to allocate network bandwidth according to the user’s needs to avoid excessive use of bandwidth or network space. And check your network card, is it updated or working properly or not, if anything is wrong then correct or replace it for a smoother networking performance. In my next post I am gonna show you how to boost up your Internet Connection using CMD(100% Working).

05. Network Adapter Problem

Total Solution:
Restart Your Computer
After enabling DHCP, if your network connection is still not working properly then restart your computer. Because sometimes restarting computer can solve the issue. Restarting computer allows the “attached accessories (Network adapter in our case)” to fix the problem itself.
Plug-Out and Plug-In Again
If network adapter is still not working properly, then there is another choice for you. Turn off your computer and then open the case, plug out the network adapter and then after cleaning it plug in again and then check it ( in PC its easier but if you have Laptop then it could take some time but not more than 5 minutes ).
 If it is Still Not Working replace it
If network adapter is damaged a lot or if its still not working properly then you should replace it as early as possible to continue your work. You can also buy network adapters online.  Below we have recommended some, which are good quality and affordable.
