Network Controller in HP Pavilion® dv7t Select Edition series
Information on Network Controller in HP Pavilion dv7t Select Edition series.
A network controller is a device used to connect the system to the network. Ethernet controllers are most common among these network controllers. The Ethernet controllers are used to connect the system to the Ethernet. The physical layer and the data link layer functions can be done by the network controllers. The physical layer controls the data transmission and the data link layer controls the errors during the data transmission. The network controllers transmit data either by using the Ethernet or by using the token ring. Different techniques are used for data transmission. These different techniques include the Direct Memory Access, programmed I/O, interrupt driven I/O and the polling. DMA as the name implies can access the control of the system bus. In the programmed I/O, the processor will check the system by providing the MAC address to the system bus. In interrupt driven I/O, the process will send an interrupt after using the system bus. With this interrupt, the processor can understand that the control of the system bus can transmit to any other process. The microprocessor directly examines the process to check whether the process completed the use of system bus or not. If yes, then the control will transmit to any other process. This is the working procedure of a network controller. Sometimes due to various causes, the network controller sometimes refuses to work.
Common issues that might interrupt the working of network controllers in HP Pavilion dv7t Select Edition series are as follows:
- Issues in the driver
- Infection by malware
- Damaged network controller
Issues in the driver
If the driver that controls the network controller in HP Pavilion dv7t Select Edition series has any problem, then the network controller might not work. The common issues that might come with the driver are that it is outdated or it is incompatible. So if these issues occur, either you can upgrade the driver or update the driver.
Infection by malware
If the network controller in HP Pavilion dv7t Select Edition series is affected by any of the malware, then also there is a chance of it not working. This is because the malware change the software codes and thus the software is unusable.
If the network controller installed on HP Pavilion dv7t Select Edition series is a damaged one or is damaged due to any of the hardware or software issues, then is will not work. If the network controller is not placed in the correct position, then also it might not work.
