Escribe your Linksys E2000 Advanced WirelessN Broadband Router Network Routers Problem Router has been working fine since initial setup almost a year ago. Turned on computer yesterday, and it would not...

Please check whether your computer's wireless connection enabled or disabled. If you are using windows 7 this information you can find in network sharing center. By accident if WLAN is disabled it can be enabled. Also power cycling the router may do the trick.
More drastic approach is resetting the router which I recommend to reserve as last resort. With information you provided the router seems to be fine and your computer wireless need to be enabled!
good luck!

How to secure your wireless router

Most WLAN hardware has gotten easy enough to set up that many users simply plug it in and start using the network without giving much thought to security. Nevertheless, taking a few extra minutes to configure the security features of your linksys router wireless or access point is time well spent. Here are some of the things you can do to protect your wireless network:
1) Secure your linksys router wireless or access point administration interface linksys router wireless have an administrator password that's needed to log into the device and modify any configuration settings. Most devices use a weak default password like "password" or the manufacturer's name, and some don't have a default password at all. As soon as you set up a new WLAN router or access point, your first step should be to change the default password to something else. You may not use this password very often, so be sure to write it down in a safe place so you can refer to it if needed. Without it, the only way to access the linksys router wireless or access point may be to reset it to factory default settings which will wipe away any configuration changes you've made.
2) Don't broadcast your SSIDlinksys router wireless automatically (and continually) broadcast the network's name, or SSID (Service Set IDentifier). This makes setting up wireless clients extremely convenient since you can locate a WLAN without having to know what it's called, but it will also make your WLAN visible to any wireless systems within range of it. Turning off SSID broadcast for your network makes it invisible to your neighbors and passers-by (though it will still be detectible by WLAN "sniffers").
3)Enable WPA encryption instead of WEP802.11's WEP (Wired Equivalency Privacy) encryption has well-known weaknesses that make it relatively easy for a determined user with the right equipment to crack the encryption and access the wireless network. A better way to protect your WLAN is with WPA (Wi-Fi Protected Access). WPA provides much better protection and is also easier to use, since your password characters aren't limited to 0-9 and A-F as they are with WEP. WPA support is built into Windows XP (with the latest Service Pack) and virtually all modern wireless hardware and operating systems. A more recent version, WPA2, is found in newer hardware and provides even stronger encryption, but you'll probably need to download an XP patch in order to use it.
4) Remember that WEP is better than nothing If you find that some of your wireless devices only support WEP encryption (this is often the case with non-PC devices like media players, PDAs, and DVRs), avoid the temptation to skip encryption entirely because in spite of it's flaws, using WEP is still far superior to having no encryption at all. If you do use WEP, don't use an encryption key that's easy to guess like a string of the same or consecutive numbers. Also, although it can be a pain, WEP users should change encryption keys often-- preferably every week. See this page if you need help getting WEP to work.
5) Use MAC filtering for access control Unlike IP addresses, MAC addresses are unique to specific network adapters, so by turning on MAC filtering you can limit network access to only your systems (or those you know about). In order to use MAC filtering you need to find (and enter into the linksys router wireless or AP) the 12-character MAC address of every system that will connect to the network, so it can be inconvenient to set up, especially if you have a lot of wireless clients or if your clients change a lot. MAC addresses can be "spoofed" (imitated) by a knowledgable person, so while it's not a guarantee of security, it does add another hurdle for potential intruders to jump.
6) Reduce your WLAN transmitter powerYou won't find this feature on all wireless linksys router wireless and access points, but some allow you lower the power of your WLAN transmitter and thus reduce the range of the signal. Although it's usually impossible to fine-tune a signal so precisely that it won't leak outside your home or business, with some trial-and-error you can often limit how far outside your premises the signal reaches, minimizing the opportunity for outsiders to access your WLAN.
7) Disable remote administrationlinksys router wireless have the ability to be remotely administered via the Internet. Ideally, you should use this feature only if it lets you define a specific IP address or limited range of addresses that will be able to access the linksys router wireless. Otherwise, almost anyone anywhere could potentially find and access your router. As a rule, unless you absolutely need this capability, it's best to keep remote administration turned off. (It's usually turned off by default, but it's always a good idea to check.)

How TO unloack wlan


In order to unlock the WLAN and make your WiFi connection freely accessible, you will need to log in to the router and go to the Wireless Settings page.

Once you are on that page, please clear out the currently selected password for WiFi and set it to none.

Save the settings and reboot once.

Now, your WiFi will be unlocked.

You must note that once you remove the password protection any wireless device in the WiFi network range will be able to connect to your wireless network and use the same.

Vista to Vista wireless, Can't share printer

So your third laptop which runs Vista cannot connect to the Printer and Dell machine?
There are some reasons for that. First check whether you have access to the Dell machine (whether you can reach it) Open a command prompt and do a ping to verify the connectivity. Example. ping (The ip address should be the one of your dell machine. You can find it by running ipconfig in a command prompt on Dell machine.)
1. If you cannot reach it you have to check the network utility (wifi or any other method you use). Make sure that it function properly. 2. ping the router using router's ip address. If ping works you can reach up to their. So from there you can check the Lynksys management console to know why it blocks the machine entering the wlan. May be a addressing issue or authentication issue. If you cannot reach it however it might have problems with the connection as well. Make sure that you allow connections to the wlan on Toshiba Vista laptop if you use a antivirus solution with a firewall or any other firewall.
If you can reach the machine (or even if you cannot reach) you must check whether you have access to the workgroup (you have to join if you are not in the workgroup which you use) and you must enable file and print sharing. If you run the windows firewall that would block you in as well. Its better if you can check whether the print spooling service runs. Start -> Run Type in services.msc Hit enter. Check and enable the service.
If you can reach the Dell using a ping: Check whether the dell machine can access the laptop. Use my network places. It will ask you for the credentials. Provide them. If any error occurred try detecting the network. Add the machine properly to the workgroup. Enable access to the machines via file and print sharing in windows firewall. (go to the firewall go to Exceptions tab and select the File and Print sharing)
Check this Microsoft resource as well.

My wlan light keep going on and off on my wrt54g

Also check if the power light on your router is blinking. If it is blinking, that's an indication of hardware failure. To revive it, do a hard reset. Press and hold the power button of the router for 30 seconds then unplug the power. Wait for 30 seconds again before you plug it back in.

I have a sonicwall pro 2040 and while the firewall rules look correct, I cannot get traffic from the WLAN to the LAN, nor from the WLAN to the WAN.

SonicWALL Wireless Configuration Wizard To access SonicWALL’s Wireless Configuration Wizard, log on to the SonicWALL router, then click the Wireless button found within the left navigation bar of SonicWALL’s Web-based management interface. The Wireless Status page will be displayed. Click the Wireless Wizard button that appears toward the top-right of the screen.
The SonicWALL Wireless Configuration Wizard will appear. Click the Next button to proceed with the wireless administration utility.
The wizard’s first step will appear as seen in Figure A. Step one addresses wireless local area network (WLAN) network settings. You must specify the WLAN IP address and subnet mask before continuing. In addition, a checkbox is provided for enabling Windows networking support between the wired local area network and the WLAN. Be sure to check the box to enable communication between the LAN and WLAN. Then, click Next.

Step two requires setting the Service Set ID (SSID), radio mode, country code and channel. The SonicWALL wizard provides a blank field for specifying the SSID. The default SSID is sonicwall. Consider changing the SSID to a value that reveals nothing about the organization or office in which it is deployed. I typically deploy SSIDs as HomeNetwork and BusinessNetwork, as doing so provides potential hackers with less information about a network (particularly in more heavily populated areas such as apartments and office parks).
On most SonicWALL routers, including the popular TZ 170 wireless model, three radio modes are available: 2.4GHz 802.11 b, 2.4GHz 802.11g or 2.4GHz 802.11g and b Mixed mode. Using the provided drop-down menu, select the mode you wish to use within your organization.

The last item to configure within Step 2: WLAN 802.11b/g Settings is the channel. Channels one through 11 are available options. Or, AutoChannel is an alternative choice and, in fact, the default. Choosing AutoChannel allows the wireless network equipment to automatically negotiate the best channel settings. Once the channel is specified, clicking Next continues to the next step.
Step 3: WLAN Security Settings enables configuring one of three security modes for the
SonicWALL wireless router. The three security mode choices are:
  • WiFiSec VPN Security – The default selection, WiFiSec VPN Security creates an IPSec-powered VPN over which the wireless traffic travels.
  • WEP + Stealth Mode – Utilizes Wired Equivalent Protection (WEP) to secure wireless communications.
  • Connectivity – Implements wireless communications featuring no encryption or access controls.
When selecting WiFiSec VPN Security and clicking Next, the Step 4: WiFiSec – VPN Client User Authentication page appears. This step helps create a user name and password for a new user with VPN client access privileges. The WLAN WiFiSec security setting will enable the SoniCWALL Group VPN feature. If you wish to edit user privileges, you can log on to the SonicWALL router’s Web-based administrative interface and edit user permissions by clicking Users | Settings.
After a user name and password are supplied, click Next to proceed to the wizard’s fifth step. The Step 5: Wireless Guest Services screen allows you to enable guest wireless access while also specifying the guest account name, password and account and session lifetimes.
Once these values are supplied, click Next to view a Wireless Configuration Summary. Clicking Apply prompts the SonicWALL Configuration Wizard to apply the settings and configuration parameters you’ve entered into the wizard. When the wizard completes, a confirmation page should then appear (with a Finish button being the only available option).

Lost ability to connect to home network after phone/DSL failure

Recreate your wlan network.
WLAN signal refers only to radio signal between Router and PC no link with your capability to pass-through: wrong password, access list or firewall can block your access with the strongest radio signal.
Check (or recreate ) your credential on your PC.
Check if you can log as admin into your Router.
