You are a help desk technician providing support for a wireless network. A user calls and complains he cannot access the Internet. The user tells you he has good signal strength, but the network connection states "acquiring network address" and the IP address is all zeros. What could cause this problem?

From the user explanations, it can be inferred that the issue may be as a result of incorrect security parameters such as Wireless Protected Access (WPA) which ensure security for wireless connections.

Explanation:

If there is an incorrect access pass to the wireless network by the WPA, any wireless user will not be able to complete a Layer 2 connection to the wireless network after connecting and getting good signal indication and would thus be unable to obtain IP address automatically to be able to log on to browse the internet from the DHCP Server.

Incorrect connectivity configurations.

Explanation:

In many instances, the connectivity configurations may not be matching. This results in a loss in internet connectivity. Thus, the first thing  will be to check the wireless area connections settings or simply the LAN settings. In addition, the local host or server can also check their systems to see if there are no generation problems on their side. Sometimes it may happen that external factors beyond the customer control can hinder the connectivity issues.
