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.

Check both your router and your PC configurations. Follow the manufacturer's directions for configuring your router and PC for WiFi access.

SOURCE: im having problems with it staying connected for

Unplug your router/and or modem for 15 secs and try it then. Sometimes the router has to reconfigure itself in order for it to stay stable. also be sure not to have any cell phones close by, due to a lot of them operating on the same frequency.

SOURCE: Hi, my wireless internet connection

Hi,

There could be a number of causes for this issue. I will give you some tips to see if you can't resolve the issue.

Make sure your computer and software is up to date. Update windows and update any device drivers for your computer. Do a google search by the brand name of your laptop, go to the website and look up Drivers/Software specifically for your wireless card/motherboard.

The problem could be with your Internet Service provider if you are using your home network. The signal could be degraded and they will have to come out and fix that by replacing splitters and lines at your residence.

You could have an issue with your router. If your router is dropping connections there is not much you can do about this other than replace it. You can try to reset the router(you will lose settings and will have to reconfigure). In order to reset, you can press the small reset button on the back of the router and hold it for 10-15 seconds. You can also rule out the router by bypassing it, hooking your laptop up straight to the modem. If the problem goes away then you know the router is most likely the culprit.

Regards,

I keep getting authentication problem when trying to connect my smart TV to the internet. I am sure my password is correct and am aware of case sensitivity when entering password. What more can I do?

Try recovering as a factory reset since there may be some problem in your TV's connection. Once you do your factory reset all your settings will be set to default. For factory reset see your TV's Manual.

Cannot connect my arnova 7d g3 to the internet keeps saying authentication problem. can anyone help

You don't know the password to your wi-fi protected setup. They changed the password when they changed your equipment. Ensure you have the correct password and that you are not too far from the access point.

Cannot get the internet to work

That means you probably don't have the password or the Authentication Type set correctly.

For Windows XP below:
Click Start/Control Panel/Network Connections then Right Click on the Wireless Network Connection and select Properties. When the Properties window open click the Wireless Networks tab. Click on the SSID for your wireless network that you connect to and the Properties window will open. You can change the Authentication Type to match the type set in your wireless router and you can also change your password or Network Key to make sure you have it in correctly.

For Windows Vista below:

Click Start/Control Panel/Network and Sharing Center then look to the left of the open window and click Manage Wireless Networks. Find the SSID of the network that you connect to and double click it. When the window opens click the Security tab to change the Security Type (which is the Authentication), The Encryption Type and the Network Security Key (which is the password).

For Windows 7 below:
Click Start/Control Panel/Network and Internet/Network and Sharing Center then look to the left and select Manage Wireless Networks. Find the SSID of the network that you connect to and double click it. When the window opens click the Security tab to change the Security Type (which is the Authentication), The Encryption Type and the Network Security Key (which is the password).

Unable to connect to internet through Wi Fi on Nokia E65

You need to "authenticate" the wireless meaning you need the password to the web signal. Your phone may have an internal software issue in which it prevents you from connecting to the internet. Contact your phone company to trouble shoot it or get a replacement phone.

User access

what version of vista are you using, this is a very important piece of information, vista home flavors are not very network friendly,I recommend that you keep using XP until a few service packs are out for vista. If your using ultimate then something else would be wrong, possibly a setting on the vista box, Im not real sure how vista's authentication works but if they changed it enough then it might require a compatiblity mode or something in order to authenticate with 2000/xp, but then again i could be wrong and vista might authenticate exactly the same way as 2000/xp, try setting an xp box up as a server and see if the vista box can authenticate with it, if so then maybe 2000 is the problem, sorry i couldnt give an actual solution but im still new to vista myself and dont have any pc's that will run it, my good computers are all macs.
