One problem with wireless networks is that people who have wireless devices that are within the range of your network can access them. Even if you have set up a password for your wireless network, that password can also be hacked and access to your network can be gained. One way to further tighten up your network security is through MAC filtering.
MAC filtering is a network security procedure that only allows access to registered MAC addresses. A MAC address is the unique ID of a network device; no two computers or network device has the same. What this means is that only registered and authorized machines can access your wireless network. So even if they somehow managed to break or hack your password, they won’t still have access if their address is not registered. This is a very effective way to ensure the network security of your wireless home network.
What you need to do is enable the MAC filtering function of your wireless router or access points. Most routers at present have this function. Next, you need to input the MAC address of the computers in your home network. Getting the MAC address is different from one operating system to another, but this should be found in the properties of the network device. Check your computer’s manual or technical support for the procedure on getting the MAC address.
So, if you’re very particular about the network security of your wireless network, then one thing you can do is to enable MAC filtering in your network.

How to Deal With Dual Network Cards Conflict
December 29th, 2009
Many people now have two computers, as to enable both to access the network, they often make use of the dual network cards to connect their computers and make them as a local area network (or LAN), which would cost much less than purchase a router. However, sometimes due to the model and the quality of these two adapters or your PC compatibility problems, they have a conflict. How can we tackle it?
Using dual NIC cards to access the network is only a temporary plan, if there is some problem when applying the double cards connection, we should consider troubleshooting it from the aspects below:
Computer restart
Generally when you finish installing some software, Windows prompts you to restart; sometimes you think it a troublesome and reboot the computer till all software has been installed. You’d better restart your PC when installing the first net card and then turn to set up the next one. Because when installation is over, the system not only would assign the interrupt request and the memory available resource to you network adapter, but also configure the port and the IP for it, actually it is more convenient for your PC to carry out its work by rebooting and then installing the next adapter.
Net card speed and connections
When you build the network, you should think over the communication problem between the 10/100M and 10M network adapters: when they are interconnected in two computers, you would probably find that they are not reachable across the IP network, or they are shown connected normally but you can not browse the website. Such errors often happen when two net cards with different transmission speeds exchanging their data packs. To resolve this failure, you can try to contact your 10/100M network adapter to the external line and use an adapter with the same speed in the inner connection.
