Can't connect to the internet. Own a sharp Roku 50" tv. Network name is SSID. MAC address is 64:6E:69:5A:4B:7C

mac address is an unique network device equipment identifier.
How to stop it. Change encryption key when you add wpa or wep encryption to wi fi security on router. Added security - do not broadcast ssid and change it to something different.
All devices with wi fi will need to be changed to match wi fi encryption method and key and ssid name.

Model number required for specific answer.
Generic steps are to access the menu and look for options labeled internet or Network.
Choose connection type either Wired or Wireless.
If Wireless look for the network name (SSID) for your network. Select that and enter the network password.
If you plug the TV directly into your router via an ethernet cable you should automatically connect.
Launch installed app to verify connectivity.

Your gateway would not normally block unknown mac address on the lan side unless you have somebody extremely security conscious and specifically locked down the device - highly unlikely. Are you doing anything different than what is described in this procedure?

If you forgot your password, you can recover it here at this URL:
Forgot Password

A new password will be sent to the email account listed in your account. If you do not see the email, be sure to check your spam filter.

I assume you are either unable to see your network listed or when you select your network from the list of active Wi-Fi Networks within range of you device and depending on security level no password or the Security Key you have doesn't work. First, make sure you have a few pieces of information: 1) The SSID or name of the network 2) The security type and password 3) If no DHCP service you'll need the ip address subnet and an available address for your device, ip address of the gateway/router, & ip address of the DNS servers. Usually the router provides DHCP and provides all of the addressing information.

Typically, you are provided the SSID and a security key or password. On your tablet open settings and turn Wi-Fi in necessary and look for your SSID in the list to the right. If your SSID is not shown verify the name, that the router is on and you are within range. Be aware of obstructions between you and the router. My Pool House is a virtual dead zone due to some electrical wiring on the wall it shares with the office. The router is less than 5 feet away, but the signal is unreliable. If everything is working and still no SSID on list, then it may be hidden. Simply, select Add Wi-Fi Network at the bottom and enter the SSID (Netgear987), security type (WPA OR WPA2 typically) and the password (PASSWORD maybe case sensitive). If it connects and fails to obtainan ip address or just drops it may indicate another layer of security that requires each device MAC ID is added to the list of authorized devices for that router. Your MAC ID is listed on the Settings_About Device_Status screen WiFi MAC Address: (F7:C7:AE:78:E6:FC). Sounds like a lot but usually verified SSID and password do the trick. Good Luck

Roku only connects to the wireless network. In the wireless section of your router setup use MAC filtering. Enter the mac address of the roku and enable mac filtering on the router. Save the selections and that should solve the connection problem.

Get the MAC address from the TV and open your router setup page. In the wireless section enable MAC filtering. Enter the MAC address to the list save and exit. You should get a connection.

You should follow the next steps:
1. Log in via http://192.168.0.1
default username: Admin (use admin if it doesn't work) password: (leave it blank with no password) ----- 2. Go to setup tab ----> internet ----> internet connection wizard 2.1 CHANGE PASSWORD ! click next 2.2 choose time zone. 2.3 Configure your Internet Connection DHCP Connection (Dynamic IP Address) Choose this if your Internet connection automatically provides you with an IP Address.
2.4. press "clone your computer's MAC address" ; hostname: 'your computer name'
3. Go to setup tab ----> wireless settings ----> Wireless Network Setup Wizard (after this we're gonna do manual settings) 3.1 give your network a name= SSID 3.2.Automatically assign a network key (Recommended) and chose WAP or WAP2 3.3 Write down the network key Or do printscr and save this page.
You can leave it here, but it's better if you continue with the next step: -----
4. Go to setup tab ----> wireless settings ---->Manual Wireless Network Setup 4.1
Wireless Network Settings Enable Wireless : ALWAYS Wireless Network Name : (Also called the SSID) the name you gave in 3.1 802.11 Mode : chose "mixed 802.11n,g and b" Enable Auto Channel Scan : YES Wireless Channel : AUTO Transmission Rate : BEST (Mbit/s) Channel Width : AUTO 20/40 MHz Visibility Status : !!!Invisible!!! (so that no outsiders know your SSID except you)

4.2 Wireless Security Mode : WPA-Personal
4.3 WPA mode: WPA2 only Cipher type: AES Group key update interval : 3600 seconds
4.4 Pre-Shared Key : the one that you generated in 3.2.
-----
Now you're all set, but you can't see your network from your PC (as you set it to be invisible in step 4.1). Now you'll have to set it up manually (the specific instructions will depend on your operating system) You'll need to enter the following date when you set it: your SSID name that you entered in 3.1 wireless security: WPA2 personal type: AES enter password that you've generated in 3.2 (or 4.4).

Dear sir, Here's How:

1. Choose a convenient location to begin installing your router such as an open floor space or table. This does not need to be the permanent location of the device. Particularly for wireless routers, you may find it necessary to re-position the unit after installing it as the cables / signals may not reach all areas needed. At the beginning, its better to choose a location where it's easiest to work with the router and worry about final placement later.
   
   
2. Plug in the router's electrical power source, then turn on the router by pushing the power button.
   
   
3. (Optional) Connect your Internet modem to the router. Most network modems connect via an Ethernet cable but USB connections are becoming increasingly common. The cable plugs into the router jack named "WAN" or "uplink" or "Internet." After connecting the cable, be sure to power cycle (turn off and turn back on) the modem to ensure the router recognizes it.
   
   
4. Connect one computer to the router. Even if the router is a wireless model, connect this first computer to the router via a network cable. Using a cable during router installation ensures the maximum reliability of the equipment. Once a wireless router installation is complete, the computer can be changed over to a wireless connection if desired.
   
   
5. Open the router's administration tool. From the computer connected to the router, first open your Web browser. Then enter the router's address for network administration in the Web address field and hit return to reach the router's home page.
   
   Many routers are reached by either the Web address "http://192.168.1.1" or "http://192.168.0.1" Consult your router's documentation to determine the exact address for your model. Note that you do not need a working Internet connection for this step.
   
   
6. Log in to the router. The router's home page will ask you for a username and password. Both are provided in the router's documentation. You should change the router's password for security reasons, but do this after the installation is complete to avoid unnecessary complications during the basic setup.
   
   
7. If you want your router to connect to the Internet, you must enter Internet connection information into that section of the router's configuration (exact location varies). If using DSL Internet, you may need to enter the PPPoE username and password. Likewise, if you have been issued a static IP address by your provider (you would need to have requested it), the static IP fields (including network mask and gateway) given to you by the provider must also must be set in the router.
   
   
8. If you were using a primary computer or an older network router to connect to the Internet, your provider may require you to update the MAC address of the router with the MAC address of the device you were using previously. Read How to Change a MAC Address for a detailed description of this process.
   
   
9. If this is a wireless router, change the network name (often called SSID). While the router comes to you with a network name set at the factory, you will never want to use this name on your network. Read How to Change the Router SSID for detailed instructions.
   
   
10. Verify the network connection is working between your one computer and the router. To do this, you must confirmed that the computer has received IP address information from the router. See How to Find IP Addresses for a description of this process.
    
    
11. (If applicable) Verify your one computer can connect to the Internet properly. Open your Web browser and visit a few Internet sites such as http://compnetworking.about.com/.
    
    
12. Connect additional computers to the router as needed. If connecting wirelessly, ensure the network name (SSID) of each is computer matches that of the router.
    
    
13. Finally, configure additional network security features as desired to guard your systems against Internet attackers. These WiFi Home Network Security Tips offer a good checklist to follow.

Tips:

1. When connecting devices with network cables, be sure each end of the cable connects tightly. Loose cables are one of the most common sources of network setup problems.

What You Need:

• A network router (wireless or wired)
• Network adapters installed on all devices to be connected to the router
• A working Internet modem (optional)
• A Web browser installed at least one computer in the network
