What can we do about the "connected but no internet" issue?

netsh winsock reset
netsh int ip reset

ipconfig /release
ipconfig /renew

ipconfig /flushdns

What is NIC teaming, bonding, link aggregation and how are they different from bridging multiple NIC cards?

Network Interface Card (NIC) teaming, otherwise known as network link aggregation, is a function that allows multiple connections to a network to function as a single logical link. This increase the overall bandwidth of the connection by load balancing all network traffic equally across each link. Windows 7 includes the ability to aggregate network links to take advantage of increase bandwidth. Network link aggregation requires each link to connect to the same logical network, which is usually different ports of the same network switch.

Link aggregation is a computer networking term to describe various methods of combining multiple network connections in parallel to increase throughput (but not necessarily speed) beyond what a single connection could sustain, and to provide redundancy in case if one of the links fail. Other terms used to describe NIC teaming includes "port trunking", "link bundling", "Ethernet/network/NIC bonding", "Link Aggregation Control Protocol (LACP)"

Bridging multiple NICs is creating a regular network bridge. A network bridge allows multiple networks to communicate together. You can use your computer as a network bridge. On Windows 7, you can create only one network bridge on a computer, but one bridge can handle any number of network connections. On Windows 7, to create a network bridge, navigate to Network and Sharing Center, and click on View network connections. Hold down the CTRL key and select each network connections or devices that you want to add to the bridge. Right-click on the selected network devices, and then click Bridge Connections.

What is the requirement for NIC teaming or link aggregation on Windows 7?

  1. The NIC cards may need to be identical
  2. They must be connected to the same network.
  3. You may have manually configure TCP/IP on each NIC. Each link must belong to the same IP subnet. Each link must also belong to the same virtual LAN if applicable.
  4. Windows 7 automatically aggregates the network links

What is the purpose of bridging multiple NICs?

Bridging multiple NICs is creating a regular network bridge. A network bridge allows multiple networks to communicate together. You can use your computer as a network bridge.

How to bridge multiple NICs on Windows 7?

  1. Navigate to Network and Sharing Center
  2. Click on View network connections
  3. Hold down the CTRL key and select each network connections or devices that you want to add to the bridge.
  4. Right-click on the selected network devices, and then click Bridge Connections

On Windows 7, how many network bridges can we create?

Bridging multiple NICs is creating a regular network bridge. A network bridge allows multiple networks to communicate together. You can use your computer as a network bridge. On Windows 7, you can create only one network bridge on a computer, but one bridge can handle any number of network connections.

What considerations should we make when we create a network bridge?

You shouldn't create a bridge between an Internet connection and a network connection because it creates an unprotected link between your network and the Internet, which makes your network accessible to anyone on the Internet.
