Why can't I come from the internet
Internet does not work - here's what you can do: Checklist for problems
There can be many causes when the internet stops working. In order to quickly identify and remedy the error, it is best to proceed step by step using our checklist.
You will immediately notice that the Internet is not working: Instead of a website, you will see an error message in the browser, and instead of a video, a still image. But the cause is less clear: Because for the Internet connection to work, many participants have to work together - end devices such as notebook and smartphone, WLAN, LAN or powerline in the home network, the router at home as well as the Internet provider and his network. In order to find the error quickly, it is best to proceed step by step using this checklist.
Step 1 - A quick look at the router often helps
A problem with the Internet connection in the home network can have three causes: The device with which you want to go online is causing problems. The home network connection via WLAN, LAN or Powerline is faulty. Or the cause has something to do with the router. The faster you can isolate the area of error, the faster you will be back online.
This is why your first look at an empty website or a still video image is to the router: If the LEDs there are flashing or glowing red, you can immediately switch to step 12. If everything looks good, it doesn't hurt to try step 11 right away.
Step 2 - Check online access on another device
Before troubleshooting the device on which it occurred, you should resort to other hardware that is connected to the router. If Internet pages can be displayed with this, continue with step 3. If not, try to call up another website on your system first to ensure that the page you want is not currently available. Try a different browser for this. If that doesn't help, you have to take a closer look at the central settings on the router, as described from step 7.

Step 3 - Check the WLAN connection
If the device that you use to access the Internet is connected to the router via WLAN, next check the status of this wireless connection: To do this, take a look at the Internet symbol at the bottom right in the task bar of the Windows desktop. If you recognize the icon with the WLAN rays there, everything is OK and you can jump straight to step 9.
If you see a small globe instead, you can find out more by hovering the mouse pointer on it: If the message reads “Not connected - no connections are available”, you should check the WLAN hardware more closely. Call up the Windows info bar by clicking on the connection symbol. If the "WLAN" button is gray instead of blue, click on it to activate the WLAN adapter. If nothing happens, you should check in the Windows Device Manager whether the entry for the WLAN hardware has an error symbol. In this case, a Windows restart is required, because the WLAN adapter often does not wake up after a standby. To rule out this problem in the future, select the "Power Management" tab in the properties of the WLAN adapter in the Device Manager and deactivate the first option. If the device remains uncooperative, look for suitable, up-to-date drivers - either from the PC / notebook manufacturer or directly from the provider of the WLAN module - and install them.
If the message in the task bar reads "Not connected - connections are available", the computer has recognized wireless networks but has not connected to any. This could be because you selected the wrong network or made a mistake when entering the WiFi password. In this case you should therefore establish a new connection with the appropriate user information. If Windows still complains that it cannot connect to this network, go to step 8.
If the problem occurs on a notebook or smartphone, although you are sure that the connection has already worked, it may be due to the WiFi range: You have moved too far away from the WiFi router with the mobile device. Go closer to the router and log into the WLAN: If the connection then works, but breaks down again at the distant location, you can move the WLAN router or increase the WLAN range using a repeater or WLAN powerline adapter.
The globe in the Windows taskbar also appears when you are connected to a WLAN that does not have Internet access. In this case, try to see whether the problem can be solved by disconnecting the wireless connection to the router and re-establishing it or, alternatively, restarting the computer.
Still no internet connection? Then go to step 5.
Step 4 - Check the LAN connection on the end device
If the computer is connected to the router via a LAN cable, investigate this connection path: The cable should not be kinked or squashed and should be securely attached to the LAN socket of the PC or notebook as well as to the switch of the router. A quick test with a replacement cable rules out a cable fault. If the connection to the router is via an external switch, check whether it works. Otherwise, proceed as described in step 3: Restart the system, check the LAN hardware in the device manager and install new drivers if necessary.
Step 5 - Check the IP address on the end device
So far you have checked whether there is a problem with the hardware connection in the home network. Now it's the turn of the software. The Windows command line is the tool of choice for this: Its commands not only help you with Internet problems, but also fundamentally with the analysis of the home network - you will find the most important in the box below.
For a quick check, it is sufficient to enter the command ipconfig: After “IPv4 address” you will see the IP address currently owned by the computer on which you started the command line. You will find the internal IP address of the router under “Standard gateway”: You may only differ in the last digit.
If you don't, go to Windows settings and select “Network and Internet -› Change adapter options ”. Right-click on the connection with which you want to reach the router - for example "WLAN connection" or "LAN connection" - and go to "Properties". Select "Internet Protocol Version 4" and click on "Properties". The option "Obtain an IP address automatically" and "Obtain DNS server address automatically" must be activated here. Then check the corresponding settings in the router as described in step 10.
Step 6 - Set the security software correctly
Check whether you have activated firewall options in your security software that prevent online access - for example, because you have prohibited a certain program such as a browser or an app. Intermediate stop: check WLAN repeater and powerline adapter If the end device that is having Internet problems is not directly connected to the router, also check whether the intermediate stations are working correctly: To do this, take a look at the status LEDs of the repeater or powerline adapter Adapter. A flashing or red light indicates problems that can possibly be solved by a restart.
With a powerline adapter, you should then perform a so-called pairing again, i.e. reconnect the adapter to the powerline network or to the powerline adapter that is attached to the router. This usually works via a button on the housing - how exactly is in the manual.
If the connection is established again, now is the time to take care of a firmware update for repeaters and powerline adapters: To do this, call up the relevant browser menu of the device and look for an option such as "Update".
