There are couple solutions. One of them is just to buy a powerful router ($100 and more range) and good wireless cards. Another solution is more complicated and it's based on so called "bridge". To create a bridge you need to have two routers (it's highly recommended to use the same brand and model) supporting bridge technology and of course wireless routers or lan cables to connect computers inside of the houses to routers.
First solution is cheaper but has shorter range. Second is more expensive but has longer range.
The Athena the questioner mentioned is a brand of powerful WiFi range extender that operates in the usual 2.4GHz and 5GHz bands.
As their range is about 120 feet it would take a line of about 132 Athenas to reach a "single location" 3 miles away.
If you have wired internet does that mean you have wifi?
As with so many questions here, the first word of the answer could be "Depends". In this case it depends on what you mean by "wired". If the wire you refer to is the one that comes into the house from the street, you could have a WiFi router attached to that wire so that you could use WiFi enabled PCs in any room of the house.
If "wired" means that the router is connected to your PC with a Cat5 cable, or wire, then no you are not using WiFi. The PC could still be WiFi enabled but with no WiFi connection to the router you can't use the facility.
An attacker can spoof the SSID simply by using an SSID of NULL in all messages.
On my acer aspire 5720 I find that they all seem to work fine.. Do you mean that they don't do anything at all ? because I want to change what the mail button does but they do all seem to open something and I have not had to configure anything.
Wired Communication is the transmission of data over a wire-based communication technology. Examples include telephone networks, cable television or internet access and fiber-optic communications.
Wireless not working and is switched on but windows diagnostics says it is not on?
Try using utility from the wireless adapter manufacture. Also there are always two options to manage wireless cards. By default windows wireless zero does not have access to the wireless adapter. Try changing the last option in wireless adapter properties.
WPA-PSK is a type of encryption which must be used if you have choose between WEP and WPA-PSK. If you have an option to use WPA-PSK2 to use it because it's even better.
PS: The problem with WEP is that it takes about 5 minutes to hack it. For WPA-PSK with password of at least 8 symbols it might take years if the password is complicated enough.
What two precautions can you take when setting up a wireless network?
On the file side, don't put files in a shared folder that you don't want someone to see.
On the wireless side, set up a password that is not easy to guess.
How can a bridge know whether to forward frames?
How can a bridge know whether to forward frames?
Answer:
The bridge builds a list of MAC addresses on either side of the bridge. Therefore, it knows which packets should be forwarded to the other side and which should not. In the example of a packet that uses a MAC address not in its table it can err on the side of caution by forwarding the packet.

How do you WiFi battle in soul silver?
im pretty sure you have to have ppl registered in your palpad then go down stairs in the poke center then talk and i guess battle or somthing im really not sure either......

The function of ARP (address resolution protocol) is to obtain the MAC address of a host, and then map that MAC address to the host's IP address.
This protocol is used to translate physical addresses to internet protocol (IP) addresses.
A physical address can be the MAC (Media Access Control) address of a network card inside of a computer.
The information about which hardware address is associated with which IP address is usually stored in a table on each computer, the so-called ARP table.
In essence, ARP is used so that machines on the same network can find each other. It facilitates data exchange between computers on the same network.

How do you secure folders over home network?
You don't really need to "secure" a folder to send it over the network as the wireless encryption takes care of it for you. You can use a third party folder encryption app or compress the folder and give it a password if you really want to have overkill.
If you're just on a Home network, as in using it in your home, then all you need to do is set the wireless encryption to WPA-2 (it's the highest non commercial encryption) and everything you send to the other computers is encrypted.
Depending on the uniqueness of the password, (length of password, how many numbers, random letters, uppercase letters, etc.) it could take years to decrypt even with a high end "cracker".
What do you need to set up a network for five buildings three floors high with about 1850 users?
Contact an IT solutions company. This is way to big of a job for anyone without extensive knowledge in the field. It will likely require multiple servers, operating systems, lots of wiring, lots of computers, backup solutions, multiple internet connections w/routers, probably some wireless access points, tight security, etc. Depending on the configuration, the hardware alone will easily exceed a million dollars, and labor will likely run $100+ per hour. With that much money being thrown around, contract the initial installation and hire an internal IT department for day-to-day matters and to assist in the set-up. This system will cost a few hundred thousand per year to keep up, too, with the staff for the department.
Unfortunatley, I have to completely agree with the answer the previous user submitted, I wish I had better news for you, buddy
I would suggest mini server rooms in each building, local network cabinets on each floor, each buliding connected to each other by at least two links for redundancy. You would need from the infrastructure point of view, switches, routers, cabling, ports.
From the computer point of view you would need servers and workstations. You would need to consider Backups and replication, patch management and Anti virus, licencing software and firewalls.
ANSWER
Picture the physical layout and all the wiring between.
- Each floor will need to connect all the cubicles.
- Each floor will need to connect to the other floors in the same building.
- Each building will need to connect to the other buildings.
Servers are one detail, but the network to support 1850 users will require several subnets on the local infrastructure LAN. At a minimum, items (1,2,3) will each have its own subnet (and therefore separate routers). A subnet can typically support 253 systems, but usually that will swamp the network and your users will be screaming at the I.T. department. As described by the question, 5 buildings with 3 floors each will required 15 routers and on average each router would have 123 connections which is a reasonable start.
Each router or switch deployed should be a gigabit device while all systems attached should be restrained to 10/100mb connections.
