Your HPProBook 6440b has come with the exciting hardware support to fulfill the need of speedy computing. This has come with the latest hardware to give you pleasure in all the fileds of computing. This has a very high performance network adapter to communicate with other computers. Again, HP ProBook 6440b is also provided with 802.11 b/g/n integrated wireless LAN network which lets you share your data at a minimum speed of 11 MB/sec.
Now we will discuss in detail about the common problems that can come in wireless network in HP ProBook 6440b and tips to resolve them:
- Driver Problems
- Network problem caused by overlapping of frequencies
- Propagation delay due to some obstacles in wireless network
This is a very common problem for wireless network. Sometimes your operating system may not find the wireless network card or sometimes this may not work due to driver problem. It is mandatory that you install device drivers to operate a device. Drivers are software that makes a communication bridge between your operating system and the device. A driver works as an interpreter . So you need to install the proper driver. Again, although you install the driver yet you may still face some problems with your device. You need to update the driver to solve this issue. To update the driver, go to: ‘Start’, ‘Control panel’, and ‘System and maintenance’ one after the other. Next, click on ‘Device manager’ and ‘Networks’, and then right click on ‘Network’ and finally click ‘Update driver’. You can also download the update from the Internet and install it by double clicking the .exe file.
Network problem caused by overlapping of frequencies
Your HP ProBook 6440b is integrated with 802.11 b/g/n wireless LAN card. This wireless network card operates between the frequency band of 2.4 GHz. But many other devices also operate in this frequency spectrum. Your cordless phone uses the same 2.4 GHz frequency spectrum and thus causes overlapping of network. This makes the network busy and noisy. Thus delay occurs and you may also lose the connection from time to time. Again a device like microwave oven also causes wireless issue by using the same frequency spectrum. To solve this problem, you need to keep your laptop away from these types of devices.
When some obstacles like furniture, walls etc stand in the path of your wireless connection, a delay is caused and this in known as propagation delay. This reflects the waves of your wireless network and also prevents the signals from going through these types of obstacles. As a result, a delay is caused and network connection problems occur. You need to keep avoid such obstructions to your laptop so as to avoid delays.
