Hi, Michael-Best, Your suggestion hasn't worked. There are a few virtual adapter on the laptop which I tried disabling before restarting. It worked for a while and then has gone back to the same even though I have disabled these virtual adapters again. Thanks

HI Experts,<br />
<br />
I have a Dell laptop M4600. The wifi adapter is playing up. We changed the wifi adapter. but the problem still persists. I tried uninstalling the driver, restart the laptop and install the drivers. It works fine till the next restart after which everything goes back to the old situation. In the device manager, there is an exclamation mark next to the wifi adapter and also there is an unknown device elsewhere in the device manager.

HI Experts,

I have a Dell laptop M4600. The wifi adapter is playing up. We changed the wifi adapter. but the problem still persists. I tried uninstalling the driver, restart the laptop and install the drivers. It works fine till the next restart after which everything goes back to the old situation.

Wireless networking is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure. The key hardware components of a wireless computer network include adapters, routers and access points, antennas and repeaters.

Wireless Hardware

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Networking Hardware-Other

Wireless networking is anything related to the transfer of data between two (or more) devices without the use of a physical connection, ranging from getting advice on a new Bluetooth headset to configuring sophisticated enterprise level networks.

Wireless Networking

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.

Windows Networking

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.
