Unidentified Network Problem?

[Alexus Benji]

So a while ago I asked the same question. But it didn't work. So I'll explain things all over again. Every couple of days my internet would just stuff up and I would go on my computer and see that it says (Unidentified Network) (I'm using Ethernet) with a caution symbol on my computer and Ethernet cable symbol. I've tried restarting the internet and waiting for 5 mins (Both router and modem) But still nothing is working. Please help!

Troubleshooting Internet Connectivity Issues
The causes for this problem could be many and for troubleshooting the problem it is important to have a guide or methodology in diagnosing the issue, so that you can fix the problem in the shortest amount of time, so I decided to put together a step by step guide on how to approach this problem. It is important to know that internet connectivity issues may be software or hardware related.

Step 1: Before you start doing anything, the first thing you should check is if your modem and router are online and check the lights to make sure they are, this step is often overlooked and sometimes all you have to do is power cycle the modem and router and you are back online.

Step 2: If they are offline, just unplug them from the power and wait a few minutes, then plug the modem first and let it get online, once the modem is online then plug the router, it has to done in this order, because it takes the modem longer to get online and if the router gets online first it will assign itself it’s own IP address and you won’t be able to connect to the internet.

Step 3: If your modem and router are online, the next thing to check would be the cables themselves and make sure everything is connected properly and that there is no damage to the cables, I like to do this first, because it doesn’t take much time and it could very well be the problem. Also if you have a laptop make sure the switch for the wireless is on. It is important to check for simple things first, because you can do it quickly and do it just before you start playing with all the settings, it might save you a lot of time.

Step 4: Open up your browser and check if you can get online, if you can’t connect; try connecting a different computer and see if it works. If you can get online with the other computer that means that modem and router are working fine and the problem is with your computer. Also try a different browser like firefox or chrome and see if you can get online that way. If you do, that means that you have a browser problem. Now if you have an internet security suite or antivirus installed, sometimes they turn off your internet connection for whatever reason, so it’s a good idea to check the settings and make sure your internet is not being halted by those programs.

Step 5: For Internet Explorer you can reset all the settings to default, that usually fixes the problem, just open Internet Explorer go to Tools\Internet Options\Advance and click on reset. Once you do this, all your add-ons will be gone so you’ll have to reinstall them, but your internet should be working now.

Step 6: If this fails, check if you are getting an IP address, just go to Start Menu and on the search bar type cmd, that will bring the command line and type ipconfig/all and see if you’re getting an IP address, if you do then do a loopback ping test to see if your network card is working properly on the command line type ping localhost If this checks out ok, next thing you could do is to check your DNS service, in the command line type ping 4.2.2.2 this is a well known DNS server on the web. If you get a reply back, that means your problem may be that your DNS service is down.

Step 7: If you have a problem with DNS, make sure your network card is set up to DHCP so that it can connect to the proper DNS servers, you can access this feature on control panel\network connections and double click on the network adapter icon, then click on properties and highlight where it says Internet protocol (TCP/IP) and hit properties and make sure the Obtain an IP address automatically is selected.

Step 8: Try uninstalling the network card driver and reinstall an updated version if possible, also you can try uninstalling your browser and reinstalling it, that could also fix your problem.

Tip for windows XP: One last thing you could do is use a free software called Winsockxpfix, this tool works only on Windows XP, this is something you could do first if you like, because it doesn’t take long to run and I had great success with it in the past.

what does the IP says ? Looks like you lose the IP and the gateway is no longer reachable.

maybe time to call your ISP for a visit.
