On a regular basis, we receive calls about problems when someone connects a notebook to the in-house wireless network. If everything else on the network is functioning properly, then we look at two devices, the notebook’s wireless interface and the access point they are connecting to. An access point allows wireless devices to connect to it and forwards on requests.
Some specific problems that can occur:
- The wireless interface on the notebook is older and does not support the newer protocols on the access point. Therefore, the interface is stepping down the speed.
- The access point does not support the newer protocols on the notebook and therefore the access point steps down the speed.
- A malfunction with either can result in loss of signal strength or interruptions.
If other wireless devices are functioning properly, then the problem is likely the notebook’s wireless interface. This can be tested by replacing the built in wireless interface with a USB wireless interface.
If other wireless devices are not functioning properly, then look to the access point for the problem. Older or low cost home based access points may have internal problems or lack up-to-date higher speed protocols.
Another situation to consider is allowing employees to use the wireless network for personal devices that are not work related. These devices should be on a guest network and isolated from company resources. A guest network can also serve clients or vendors that come into your office. Company wireless networks should be locked down and accessible only for company related tasks.
At K&ATS we can help determine the cause of wireless issues and provide solutions backed by site surveys, wireless updates, guest networks, and company networks.
