Steps taken]]> 2019-05-08 03:41:46 UTC https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/357899682 Problems & Solutions https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/357899860 Problem:
IP Conflicts
Solution:
 Re-configuring your DHCP setup to ensure that static IP addresses are excluded from the pool. This will reconfigure IP addresses appropriately, which will resolve the conflict and in return will lead to all machines on the network getting the proper access that they are supposed to get. 
- Syed & Alex]]> 2019-05-08 03:43:17 UTC https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/357899860 problem: Can’t get an IP address https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/357899895 Sloution: If only one user is affected, check the NIC settings to be sure it is configured to use DHCP. Next, check the switch to see which VLAN the port is configured as a member. Check that other devices on this VLAN can get addresses. If they cannot, the problem may be that the router is not forwarding DHCP requests to the DHCP server. If many devices across several subnets are having this problem, the problem is likely the server itself. The server may not have the DHCP service running, or it may have run out of addresses to distribute. ]]> 2019-05-08 03:43:28 UTC https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/357899895 network card issue https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/357900119 ping another computer

Solution: you might need to strip and replace the entire system]]> 2019-05-08 03:46:28 UTC https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/357900672 kjlhj'dajhajh https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/359314484 2019-05-13 03:19:21 UTC https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/359314484 1 https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/365445679 2019-06-04 00:29:36 UTC https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/365445679 10 IT Problems https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/365445680 NIC issue? Try and ping device from another computer, if unsuccessful, you need to check firewall settings, and if that is still not helping, you need to replace your NIC

9. Slow internet? Check the router settings via IP address, and you can see where all data is going, you can also partition the internet to allow more data to your device]]> 2019-06-04 00:29:36 UTC https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/365445680 Failed network protection https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/365445684 Problem: Malicious interference has occurred within the network resulting in stolen and corrupted data packets.

Solution: Implement network protection software, such as Windows Defender, to prevent such interference from occurring.]]> 2019-06-04 00:29:38 UTC https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/365445684 Errors such as The network path cannot be found or IP address could not be found https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/365445826
Solution
Check the internet protocol version 4 (TCP/IP) and the adapter will show if you have incorrect DNS server so then just click obtain DNS server automatically. ]]> 2019-06-04 00:30:23 UTC https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/365445826 Problems related to connectivity https://padlet.com/neatbytes/o5nz1zs9ppnn/wish/365445875   A quick inspection of your router or hub will tell you if some machine is disconnected, or if the culprit is a faulty cable.

If only a single workstation is displaying the “No internet” message when opening a web browser, we can usually assume that the rest of the network is healthy and turn our attention to any hardware and software that is particular to this system.

Solution: Eliminate the obvious communication barriers such as a bad cable, poor WiFi signal, failing network card or incorrect drivers. Ensure that the workstation’s network adapter is configured with the correct IP, subnet, and DNS servers.

Check any firewall software on the device to ensure that necessary ports are open to the external network. Common ports include 80 and 443 for web traffic, plus 25, 587, 465, 110, and 995 for email.

Two computers are trying to use the same IP address.
A1. Change the IP address of one of the computers.
Q2. Router connection to WAN has dropped out due to WAN issue. WAN issue is now resolved but router still says no WAN connection.
A2. Turn the router off for 10 seconds an then back on.
Q3. Ethernet cable is not working.
A3. Check Ethernet cable is not damaged/broken/improperly-terminated with an cable testing tool.
