I have a Dell Inspiron 6000 laptop and Netgear WGR614v6 that connect wirelessly, however, I cannot connect to the internet. I can connect the laptop to other wireless connections without any interruption. Is this an IP problem or something else? Please help me to fix this issue.
Physical connections are an oft-overlooked common culprit. Check all wireless access point (AP) or wireless router ports to ensure that Ethernet cables are inserted tightly and link status LEDs are green at both ends. If not:
Verify that devices at both ends of each Ethernet cable are powered on and that ports are enabled. For example, your AP may be connected to a wall port that is disabled, or the upstream switch or modem may be off.
Try swapping Ethernet cables to isolate a damaged cable or connector.
Check your AP or router manual to ensure that you're using the right type of cable. For example, Internet/WAN ports may require crossover cables.
Connect another Ethernet-capable device, such as a laptop, to the affected AP or router port. If link status LEDs change, the device that you just replaced may be failing link auto-negotiation. Check port configurations at both ends and reconfigure as needed to match speed and duplex mode.
It might seem obvious, but it's important to ensure the client's Wi-Fi adapter used for network troubleshooting is enabled and ready to connect.
When using a Windows client, select your wireless network adapter from the Network Connections Control Panel and check to see if its status is Enabled. If not, right-click to enable the connection.
If this fails when using a laptop, look for a function key or physical button or slider-switch to take the laptop out of airplane mode. If this fails when using a removable client such as a USB adapter, remove and re-insert it.
When using an Apple iOS client, use the Settings app to verify that your iPhone or iPad is not in airplane mode and that Wi-Fi is on and ready to connect. For further iOS client troubleshooting, see Part 2 of this series.
On an Android client, use the Settings app in a similar manner to verify that your smartphone or tablet is not in airplane mode and that Wi-Fi is on. For further Android client troubleshooting, see Part 3 of this series.
Use your wireless access point or router's administrative GUI to verify network settings for the wireless network service set identifier (SSID) to which your Wi-Fi client is trying to connect.
Locate the SSID that you're troubleshooting. On a basic wireless router, there may be just one SSID, or one for each radio band (2.4 GHz and 5 GHz). On a small business or enterprise AP, there may be several SSIDs used to segregate wireless clients and their traffic.
Identify the IP subnet [and, if applicable, virtual LAN (VLAN) ID] assigned to that SSID. Upon successful connection, your Wi-Fi client should receive a local IP address from this subnet.
Identify the router or AP's own local IP address that should be reachable through this subnet (and, if applicable, VLAN).
Check your router's events log or status GUI to verify that an IP address from this subnet is indeed assigned to your Wi-Fi client when it connects.
Although we describe using Windows to manage wireless connections here, troubleshooting is conceptually similar when using other kinds of Wi-Fi clients.
Open the network connections control panel and select your wireless network adapter. If the status is still Disabled, return to step 2.
If status is Not Connected, select your wireless network's SSID and click Connect. If your network's SSID does not appear in the list or you cannot connect to your network, go to step 8 to debug wireless settings.
While attempting to connect, status may change briefly to Authenticating or Acquiring Network Address, then Connected. At that point, use Status/Support to determine the client's assigned IP address. If the client's IP is 0.0.0.0 or 169.254.x.x, click Diagnose. If that persists, go to step 8.
Otherwise, if the Wi-Fi client's IP address is not in your AP or router's subnet, use the Properties/Internet (TCP/IP) panel to reconfigure the connection to get an address automatically and repeat step 4.
Once your wireless client has a valid IP address, use ping to verify network connectivity. Run a Command Prompt window from the wireless client's Start menu and use it to ping your AP or router's IP address with the Internet Control Message Protocol as shown in Figure 5.
If pinging your AP or router repeatedly fails, skip to step 6. If pinging your AP or router is successful, then ping any other wired or wireless LAN client that you wish to share files or printers with. If that ping fails, then the destination may be using a firewall to block incoming messages.
After disabling the destination's Windows firewall, ping again. If ping is now successful, then the firewall you disabled may also be blocking Windows network protocols. Reconfigure the firewall to permit the traffic you want to exchange between LAN clients.
For example, re-enable the firewall and permit inbound file and printer sharing.
If your wireless client still cannot connect, get a valid IP address or ping your AP or router, then it's time to consider wireless-specific problems.
The wireless AP or router and client must use compatible 802.11 standards and the same network name (SSID). Use your AP or router's admin GUI to view WLAN settings and compare them to your client's wireless connection parameters.
If your SSID does not appear in the Client's Available Networks list, enable SSID broadcasts on your AP or router. Alternatively, add the SSID to your client's Wireless Networks list, allowing devices to connect even if the SSID is hidden. Be sure to match the SSID exactly, including capitalization.
802.11ac, dual-band 802.11n and older 802.11a clients can connect to 802.11ac or 802.11n APs or routers using channels in the 5 GHz band.
802.11n and older 802.11b/g clients can also connect to 802.11n APs or routers using channels in the 2.4 GHz band.
To connect older 802.11a or 802.11b/g clients, enable Mixed Mode and slower modulation and coding scheme rates on your AP or router. For example, to connect to 802.11b clients, at least the 11 Mbps rate must be enabled. To connect to 802.11g clients, at least the 54 Mbps rate must be supported. Even slow rates are needed to connect to old clients over longer distances.
If RADIUS is working but the client's access requests are rejected, look for an 802.1X Extensible Authentication Protocol (EAP) or user login problem.
Your client must support one of the EAP types your server requires and must supply a valid login and password, token, certificate or other kind of credential.
If Netgear router has been connected to the internet and worked in the past, confirm the signal from your internet service provider (ISP) is not the problem.
1) Turn off the wireless function and directly connect your Dell Laptop to the router with an Ethernet cable.
2) Reboot the computer and check for an internet connection.
3) If there is still no internet connection reboot the router.
If you are still not getting an internet connection, contact your Internet Service Provider.
