You have to enable WEP or WPA Security on your Wireless Router.  WPA is the best protection for wireless router now.  WEP is crackable but it's better than nothing.  Normally the password for Linksys router is "linksys" (Without Quotations) If it's not try the word password, if that's not it reset your router to the original factory settings and check your documentation for the default password.\nCheck these articles from linksys\nhttp://www.linksys.com/servlet/Satellite?c=L_Content_C1&childpagename=US%2FLayout&cid=1116602204044&packedargs=site%3DUS&pagename=Linksys%2FCommon%2FVisitorWrapper\nhttp://www.linksys.com/servlet/Satellite?c=L_Content_C1&childpagename=US%2FLayout&cid=1116519873380&pagename=Linksys%2FCommon%2FVisitorWrapper

1) Cost of installing wired connections is much more than that of wireless\n\n2) Greater access to the intranet/internet.

You will need the following\n* wireless cards for each host\n* wireless access point\n\nYou should also consider enabling WEP or WPA encryption.  Other settings that will help you keep out novice hackers are MAC Filtering, and disabling the broadcast of the SSID.

Security system? I'm running the 2wire HomePortal that came with the package. It has a built in firewall that seems to work well, much like a software firewall it'll log minor things like a port scan and others like a DDoS, haven't had any problems yet.

Well, first you might be trying to accomplish something that's unnecessary.\n\nConsider: you have two computers, each of which can connect to a network just fine. That means one of two things:\n\n1. Both machines connect to, or CAN connect to, the same wireless router;\n\n2. Each machine is connecting to a separate wireless router, for some reason.\n\nIf the answer is #1, then there's no need to connect the machines directly, because both machines already have IP addresses on the same subnet via the router.\n\nFind out the IP address for each machine (ipconfig in Windows, ifconfig in Linux and OSX) and you'll likely see they're both something like aaa.bbb.ccc.ddd, where aaa.bbb.ccc are the same and ddd are different.\n\nAt that point, you can hit one machine from the other using the IP address of the other machine (try "ping aaa.bbb.ccc.ddd", from machine A using machine B's IP address.)\n\nIf the answer is #2, you're in for a more complex configuration (that can't really be answered here without a lot more information about your system) because you're asking to connect two computers directly on one network, while maintaining connections from each machine to other networks (via the network card). \n\nAt that point, the machine doesn't really know (by itself) which network to use for which kind of connection -- if you hit www.yahoo.com, should it use the wireless or the wired, it has no idea -- and so it likely defaults to the existing wireless connection.\n\nIn addition, connecting machines via crossover cable means there's no DHCP server (which would automatically provide addresses to the machines; routers have this) so the wired cards aren't configured.\n\nIf that's the case, here's what you do:\n\n1. Disable the wireless connection on both machines.\n2. Plug in the crossover cable.\n3. Using whatever method your operating system requires, set machine A like so:\n\nIP ADDRESS: 192.168.0.100\nSUBNET MASK: 255.255.255.0\nGATEWAY: (leave blank, because you don't have one)\n\n...and machine B like so:\n\nIP ADDRESS: 192.168.0.101\nSUBNET MASK: 255.255.255.0\nGATEWAY: (leave blank)\n\nNow you can ping the machines via IP address.\n\nHere's a quick note on "internal" (that is, not internet-accessible) IP addresses, by the way -- there are two ranges that are considered "reserved" for internal use.\n\nRange one: 192.168.x.y\nRange two: 10.72.x.y\n\nWhere x is a number from 0 to 254 and represents the subnet (shared by all machines that should see one another) and y is a number from 0 to 254 and represents the unique address of a single machine (so would not be shared with any other machines on the same subnet.)\n\nI hope that helps.

Not sure if this will help, but this recently happened to a friend.\nTheir situation was similar, where they kept having issues trying to connect multiple wireless devices.\n\nLooking at their router setup, someone had locked down the number of addresses the router would give out via DHCP.\n\nIt was locked down to give out only 2, and since their desktop would take one, once another device came on line, no one else would be able to surf.\n\nSo, check your DHCP settings, and see if it is limited.

You can encrypt your network. Check your manual\non how to do it with your equipment. If there's a choice\nbetween WEP,WPA and WPA2 chose the last one in\nthis list.

When setting you security you really just need information for configuring your equipment. Best place I find info for configuring wireless hardware and software is the manufacturers web site and dsl reports. http://www.dslreports.com/\nhttp://www.dslreports.com/faq/8698

First of all, you want to protect your wireless network.  This is done by the following (assuming you are using Windows):\n\n1) Put a password on the administrative site for your wireless router;\n2) Configure WEP and choose an encryption key (a string of hexadecimal digits, which the router can usually generate for you).  Write this key down, because you will need to configure all of the computers on your network to use it;\n3) Get the MAC addresses of the machines on your network.  "ipconfig -all" from a command prompt will show you the physical address.  Configure your wireless router to only allow traffic from those computers.\n\nNow, in your wireless network settings (if you are using Windows XP) if you see several networks available, you can choose the preferred order of connections to which your computer will connect.  Yours should be the first in the list and should be chosen as long as your router is up and working properly.

As all the major brands (Netgear, Linksys, D-Link) use the same type of security (WEP) none are any more secure that the others.  And there is no major difference in how they set up and operate.  So pick by price if you can find a deal on one.\n\nWhat you DO want to do to maintance security is be sure that when you set it up, you change the ID and password for the admin account, change the IP address for the router to something besides the default 192.168.0.1, and set up a WEP password.  This will make it difficult for anyone to hack in.\n\nFinally, consider turning off DCHP and using static IP addresses.  This will prevent any PC except one you have given permission from being able to access your router.\n\nThese work equally as well with any brand of router.

which wirless router are you using. you shud have been provided with a CD for the wirless router. If you isert the CD the you can configire many thing, like who can use the internet, or put a password on you wireless router, or limit the no. of divices that connects to your wireless router.\nIf you tell me the router name then i can help more, may be?

turn off your router, and when you can hear your neighbor swear then he's using your wireless connection ;-)))\n\nmore serious - most routers have an access led. when you close all your programs using the internet and the access led is still blinking, then your neighbor is using your wireless connection.\nlike others said, use WEP or WPA encryption and addional MAC filtering, then you can be sure no one will be able to use your wireless connection (that's how i've setup my wireless router).

I use paid service for security.  You can have wireless service anywhere I suppose but you cannot log in wired at home with a wired computer.  Any one can "sniff" what you are doing.  Even with your encryption and the website's encrpyption, it would be wiser to have a wired connection.  Though, it would a take very skilled person with advanced equipment to do it.

security.  You must have a security implementation of encryption otherwise you are sharing everything with anybody over the air.\nthat's the downside of wireless, unless you use WEP (at a minimum) or ideally WPA-PSK, WEP can still be cracked, but may not be worth the hackers time

The problem isn't with your computer but with your Wireless router. Your Windows firewall is probably working just fine.\n\nYou need to log in to your wireless router, create a unique SSID (located on the router), and configure security. It'll ask for a pass phrase. Save the phrase or the converted hex string and the SSID. Then you'll need to configure it into your Windows system. Check the Wireless properties.\n\nYou might also get your MAC address from the windows box (Start, Run, Cmd. In the command window, type ipconfig /all. One of the items is your Mac address. Save that.) On the router, you should be able to restrict access to the router by specific MAC. Activate that and enter your MAC.\n\nOnce that's all done, your wireless router should be reasonably secure.\n\nThis site should have expanded answers that might help if what I said above isn't as clear as I'd like it to be.\n\nhttp://www.practicallynetworked.com/support/wireless_secure.htm

If you changed the default admin password on the router and enabled encryption, thats a good start.\n\nYou could also set the router to only accept signals from your system by specifiying the MAC address of your NIC

If you are talking about your personal connection at home, you dont scramble it as such... you need to encrypt the signals using the WEP encryption feature (if your router supports it).
