Not connecting to the internet

Router ?

Problems authenticating a router in a computer is a common problem when installing a router or if your internet service gets disrupted. It is easy to solve and only requires a few steps to fix. A router forwards data from a computer to a computer network. The network can be between multiple computers, such as one would need in an office. The network can also, and more usually in households, used for connecting to the internet. Open "System Preferences" in the Applications folder in Finder. Open "Network" under "Internet and Wireless." Click "Advanced" and select "TCP/IP." Select "Renew DHCP License" and click ok. Attempt to connect to the internet. If the internet is still not connecting, restart the router and try the steps again. b> For non-Macs b> Open "Wireless Network Connection" from the wireless tab at the bottom of the screen. Select "Change Advanced Settings." Choose the "Wireless Networks" tab. Choose the wireless network you want to connect to and select the "Properties" button. Under the "Association" tab, make sure the Network Authentication has the proper security level chosen. Enter your network key if your security code is anything other than "Open" or "Shared." Select OK and try to connect. Go Back to "Wireless Networks" tab -> "Properties" and click on "Authentication" tab and un-select the "Enable authentication for the network" selection if the network key is still not authenticating the router. Select OK and try to connect.
Hope this helps.

I have an at&t 2wire 2701hg-b but i dont have at&t internet i have charter and i am not able to figure out how to get my internet to work with this router please help

att 2 wire is a Adsl Modem (Requires a telephone line jack to get the signals) but charter communication is a cable internet service (not DSL) , Requires a TV cable service for internet .
These two jacks differs and there working differs ..
Means : Att works with the username and password type of authentication but charter requires the MAC address of modem for authentication .
Therefore for a cable internet 2wire 2701hg-b modem cant be used . But yes in case charters has username and password authentication and works with the telephone jack in house then its possible to use the same modem.

I tried to change from WEP to WPA but the password will not go through. It makes it an unsecure line for wireless. What am I doing wrong?

The Short Answer:
Your password might not meet criteria. It also depends on whether you use a custom encryption key. If so, then you either need to create a 10-digit or 26-digit hexadecimal number (numbers 0-9 & letters a-f) depending on whether you use 64 or 128-bit encryption.

The Long Answer:
A WPA password must be between 8-63 characters long, and must only contain ASCII printable characters.
The 2Wire User Guide for the 2700 states the following:
"You can customize the following wireless settings in the Wireless Security panel.
1. From the Authentication pull-down menu, select an authentication setting: WEP-Open, WEP-Shared, or WPA-PSK.
Note: WPA-PSK authentication is supported only on HG model gateways.
Open authentication allows users to configure their wireless adapter as either Open or Shared; in either case an encryption key is required. Shared authentication allows users to configure their wireless adapter for Shared authentication, which requires an encryption key. WPA-PSK requires that users configure their wireless adapter using TKIP.
2. To use the encryption key that came with your gateway, click the Use default encryption key radio button.
To create a custom encryption key, click the Use custom encryption key radio button. If you select Use custom encryption key, you can define a 64-bit or 128-bit encryption key. For 64-bit encryption, enter a 10-digit hexadecimal number. For 128-bit encryption, enter a 26-digit hexadecimal number. A hexadecimal number uses the characters 0-9, a-f, or A-F.
3. Click SAVE"

Aunthentication required in connecting

Hi lovemahbeh_1,

I see that your ireless Network requires Authentication when conencting to it.

That is actually a nic feature since it will protect your Network from Others who try to connect to it.

If you do not know the Password for the router connection then you will have to get in the Routers settings to be able gain access to that specific information.

You will need to find out waht Default gateway does you Asus wireless network has for the settings.

once in the router settings you will need to look for the wireless authentication or security.

make sure the Authentication/Security in the Router is the same as what you will have in the Laptop or which ever device you use to conenct wirelessly.

I hope this helps.

Have a nice day,

How do I secure?

WIRELESS To configure the Router as a wireless access point for wireless clients (either stationary or roaming), all you need to do is define the radio channel, the Service Set identifier (SSID), and security options.ADVANCED SETUP 47 Channel and SSID You must specify a common radio channel and SSID (Service Set ID) to be used by the Router and all of your wireless clients. Be sure you configure all of your clients to the same values. SSID: The Service Set ID. This should be set to the same value as the other wireless devices in your network. SSID Broadcast: Broadcasting the SSID on the wireless network for easy connection with client PCs. For security reasons, you should disable SSID broadcast. (Default: Enable) Note: The SSID is case sensitive and can consist of up to 32 alphanumeric characters. Wireless Mode: Set the communication mode for the Router. Default: Mixed (11b+11g)Configuring the Wireless Barricade g Router 48 Transmission Rate: Set the rate of data transmitted from the Router. The lower the data rate, the longer the transmission distance. (Default: Fully Automatic.) Channel: The radio channel through which the Router communicates with PCs in its BSS. (Default: 6) Note: The available channel settings are limited by local regulations. g Nitro: In a crowded 2.4 MHz frequency, the connection speed is much lower than the promised 54 Mbps. The g Nitro implemented by Intersil's Prism Nitro technology dramatically enhances your wireless network speeds. It provides up to 50% more throughput in 11g only environment, and improves network throughput by 3 times in mixed mode.ADVANCED SETUP 49 Security If you are transmitting sensitive data across radio channels, you should enable wireless security. Configuring the Wireless Barricade g Router 50 WEP Wired Equivalent Privacy (WEP) encryption requires you to use the same set of encryption/decryption keys for the Router and all of your wireless clients. WEP mode: You can choose disabled, 64-bit or 128-bit encryption. Key Provisioning: Select a key type of static key or dynamic key. Static WEP Key Setting You may manually enter the keys or automatically generate encryption keys. To manually configure the keys, enter 10 digits for each 64-bit key, or enter 26 digits for the single 128-bit key. (A hexadecimal digit is a number or letter in the range 0-9 or A-F.) For automatic 64-bit security, check the box of Passphrase, enter a passphrase and click SAVE SETTINGS. ADVANCED SETUP 51 Four keys will be generated. Choose a key ID (1-4) from the drop-down list or accept the default key. If you use encryption, configure the same keys used for the Router on each of your wireless clients. Note that Wired Equivalent Privacy (WEP) protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet. WPA Wi-Fi Protected Access (WPA) combines Temporal Key Integrity Protocol (TKIP) and 802.1x mechanisms. It provides dynamic key encryption and 802.1x authentication service. With TKIP, WPA uses 48-bit initialization vectors, calculates an 8-byte message integrity code, and generates an encryption key periodically. For authentication, it allows you to use 802.1x authentication for an environment with a RADIUS server installed on your network. Selecting the Pre-shared Key enables WPA to use the pre-shared key in a SOHO network.Configuring the Wireless Barricade g Router 52 Field Default Parameter Description Cypher suite TKIP One of the security mechanism used by WPA for frame body and CRC frame encryption Authentication 802.1X Select the authentication mode. • 802.1X: It is for an enterprise network with a RADIUS server installed. • Pre-shared Key: It is for a SOHO network without any authentication server installed. Pre-shared key type Passphrase (8~63 characters) Select the key type as in pass-phrase or in 64-Hex characters Pre-shared Key none Specify in pass-phrase style or in 64-Hex characters. Group Key Re_Keying Disable The period of renewing broadcast/ multicast keyADVANCED SETUP 53 802.1X Management access will be checked against the authentication database stored on the Router. If an authentication RADIUS server is used, you must specify the secret key of the Message-Authenticator attribute, i.e., Message Digest-5 (MD5), and the corresponding parameters in the RADIUS Server Parameters field for the remote authentication protocol.Configuring the Wireless Barricade g Router 54 • General Parameters • RADIUS Server Parameters Field Default Parameter Description Enable 802.1X Yes Starts using 802.1x security control. Session Idle Timeout 300 seconds Defines a maximum period of time for which the connection is maintained during inactivity. Re-Authentication Period 3600 seconds Defines a maximum period of time for which the RADIUS server will dynamically re-assign a session key to a connected client station. Quiet Period 60 seconds Defines a maximum period of time for which the Router will wait between failed authentications. Server Type RADIUS Selects the authentication server type. Field Defaults Description Server IP The IP address of the RADIUS server. Server Port 1812 UDP port is used for RADIUS authentication messages. Secret Key none Defines a text string on both the RADIUS client and server to secure RADIUS traffic. The RADIUS server requires MD5 Message-Authenticator attribute for all access request messages. The 802.1x authentication scheme is supported by using the Extensible Authentication Protocol (EAP) over the RADIUS server. NAS-ID none Defines the request identifier of the Network Access Server

Why does the internet work and the light is not on, on the router?

Some routers have built-in support for PPOE and other pre-connection authentication methods.
If your ISP does not require this and it is not enabled on the router, the light will not be illuminated.

User admin failed to login (wrong authentication)

The error means that the user name or password entered is wrong. The way to recover your router is by reseting it to factory defaults see details in:
Please note before reseting to factory defaults that you will have to reconfigure the router from scratch and technical assistance might be required.

I set up a new server which is saying authentication required

Try leaving the username blank, default password is "admin. If it does not work, do you recall changing the router's username and password when you ran the cd that came with it? If you're still unable to get pass through authentication, reset the router by pushing the little reset button at the back for 10 seconds or so.

Router Password

try admin and admin again for password. If that is not it try leaving the password box blank. Good luck Are you sure you did not change the password when you set it up the first time. If you did you have no other option than reset.
