The twisted pair copper wires for DSL are already in place
It's less costly because it requires less additional equipmentIt provides high speeds of remote access
You will find that USB wireless options offer more flexibility and better performance than dial-up internet. Depending on the size of your business and its needs, however, you might find that setting up a wired or wireless network for your business is preferable.
It's a matter of choice. If you like flexibility laptop will be better for you. If you do not mind to have your computer at the same place desktop will work for you.
That is the SSID, the Service Set Identifier. It is better understood as the name of the wireless network.
Wireless internet providers work just as well as network connections. The only difference is that network connections are more controlled, since they are connected to an official server.
That depends on your preference.
A standard wireless router can only physically connect to four Ethernet enabled devices through the Ethernet ports. To extend a wireless home network, a bridge is needed. A bridge is a device that will connect devices such as gaming consoles and TVs to the existing wireless internet network that is enabled by a router. Additionally, a bridge will also extend the range of a home network, allowing for better reception to other computers and devices that are already connected to the network through wireless adapters.
Those are 2 different things. There are cable modems and DSL modems. Wireless refers to a type of network which can be based either on a Cable modem or a DSL modem. You can have a wired network, or a wireless network. Wireless networks have typically have had slower transfer rates than wired networks, but the technology is changing so wireless routers are becoming faster in transferring data.
It depends on configuration of your network. If you work in a big office, it might be a good idea to use wired connection. For smaller network with a moderate load, wireless should do just fine.
The iPad will connect to any standard wireless network - the broader the band the better.
It wireless network settings choose "do not broadcast SSID", activate security for wireless networks. It's better for you if use WPA at least.
Usually wired connection provides better stability and it is not prone to EM interference and RF noise as wireless connection. But if you have a good quality wireless adapter in your printer you will not see any difference.
Use security settings for your wireless network, such as SSID hiding, and wireless encryption. It's better if you use WPA AES at least, but WPA-PSK2 AES is better. You can use also MAC filter. But if you have WPA-PSK2 AES you do not need to because it's almost impossible to crack the encryption.
