What is the yellow triangle on internet connection icon ?

If the laptop runs a Windows OS: First of all, go to Control panel and configure network profiles

(Control Panel > Network and Internet > Open Network and sharing center > Click on Advanced Sharing Settings and then drop down both PUBLIC and HOME/WORK network profile and select “Turn on Device Discovery).

1. Right click the icon and start the troubleshooter. Let it run and analyze the outcome. There are two reasons that could be the problem. a. DNS Settings are not accurate. b. If it says limited or no connectivity (according to your description), it is the connection hardware or IP settings including DNS.

2. Right click on Computer (Or My Computer) and select “Manage” > Go to Device Manager snap-in> Expand device settings and check Network Adapter. Make sure the device drivers are properly installed. If not, you will see Red X icons or Yellow ? icons.

3. Right click the icon and again open the Network and Sharing Center (instead of troubleshooting). Then click “Manage Network Adapters”. Then go to the proper adapter and then click on Properties by right clicking. From here, you need Untick TCP/IPv6 and click on TCP/IPv4 settings and select properties. According to your issue, your laptop is not receieving an IP. check the IP settings and verify the DEFAULT GATEWAY (if you use a router, its IP is the default gateway) and DNS Server IP (provided by your ISP or Router will run DNS Services).

4. Open a command window (Start > Type CMD > Press Enter > Type ipconfig /all and enter > check the Default Gateway, DNS and write them down. If you see an IP starting with 169.254.xxx.xxx (APIPA ADDRESS) you have found the issue.

5. If you see the APIPA, go to the TCP/IP configuration panel you have opened ad set up a manual IP. You need to check the manual and find the default IP for router. They mention it (absolutely). Make sure you configure the DNS – Primary: Router`s IP, Secondary: 8.8.8.8 (Google) or use the ISP DNS addresses if the provide such.

6. If there is a Firewall (or Internet Security App) running, check Network Configuration and Allow the communication (KIS/Bitdefender/Norton).

7. Step 5 and 6 are Vital. When detected by Windows, make the network as a “WORK” network. The next step is vital too: Go to

8. Now ping the default gateway (which is the router`s IP). Open a cmd and type ping 192.168.1.1 (replace the ip with a proper address). Ping should succeed.

9. In the cmd, type nslookup google.com. The lookup should be successful. If the network is WiFi, you need to make sure the security protocols like WPA are supported by your laptop. You need to login to the router and examine the “Wireless settings” and “Security Settings” under that. Your OS supports WPA/WPA2, configure them.

NOTE the SSID and WEP/WPA key. Enable SSID Broadcast. Otherwise you need to search the network manually.

Note: In order to access the router you need to login to the admin page (http://192.168.1.1 is default or else obtained by looking at the manual).

Thank you!
