Wireless problem in HP ProBook® 4520s
Troubleshooting wireless connectivity issues in HP ProBook 4520s
HP ProBook 4520s provides two options of 15.6-inch display screen and an option of graphics with productivity and security. It has got a set of hardware components specifically for business use featured with Intel Core i3-350M 2.26-GHz processor, 500GB hard drive and 3GB RAM. The user can get his laptop set up with wireless network connection using radio frequency signal to allow communication with other networks and computers without involving any wires. Due to lack of dedicated graphics, the gaming option is not available on this laptop and the onboard speakers provide loud but very thin audio playback when placed in between the hinge and the keyboard. The main issue with this laptop is its low battery life which can be managed by extracting 1 hour 10 minutes on full screen brightness and good performance mode from its six-cell battery by charging it only once which is average but not good. The laptop might be exposed to security risks by connecting the system to an open Wi-Fi network like router or free wireless hotspot.
The following are the tips to solve issues regarding wireless network in HP ProBook 4520s:
- Safe positioning of router
- Disable service set identifier broadcast
- Enable filtering of MAC address
Safe positioning of router
Routers have to be positioned near the home center rather positioning it near windows to minimize signal leakage. Network signals usually reach out of home which might lead to little amount of signal leakage without causing any problem but if this signal goes further it might allow the hackers to easily detect and exploit owner’s secret data. These signals often reach via neighboring homes and other buildings. While installing a wireless network for home, the router’s position determines its reach.
Disable service set identifier broadcast
In wireless networking the router broadcasts Service Set Identifier (SSID) network at periodic intervals through air. This feature was basically designed for mobile hotspots and business applications allowing network clients to move in and out of range. This roaming feature is not required at home as it increases the possibility of strangers to log in to the user’s home network. Most of the Wi-Fi access points allow the network administrator to disable SSID broadcast.
Every piece of network connection gear has a unique identifier called media access control address. The MAC addresses of all devices are tracked by routers that connect them. Most of the products like this as an option to the laptop owner to key in the home equipment’s MAC addresses, restricting the network to let connections from those devices. Filtering the MAC address should be done carefully to avoid illegitimate programs to duplicate it.
