Could not establish connection to network - Symbol Motorola MC9090 Mobile Computer

If you are trying to set up a router and need to establish the SSID name and WPA encryption key, you will need to sign into the router using the routers IP address. Input the userid and password, then go to the wireless network setup page. Here is where you enable wireless operation, establish the SSID, and generate the encryption key or passphrase.

If you are trying to connect to someone else's wireless network, you need to know their SSID so that when you do a search for available networks you can determine which is theirs. Once that is established, if they give you the encryption key or passphrase, you can attempt to connect to their network. With the encryption key or passphrase, you will not be able to connect.

Have you read the last line of that message. Perhaps that would be a good place to start

prior computers have builtin network adapters that functioned as cable connection either dial up phone lin or ethernet cable connections. Computer of the recent generation have wireless adaptors that derive connective within radius of modems also known as wifi. Observe the computers made models as reference to ascertain whether requires cable connection to network or capable of wireless reception. Computers that are provided network structures by an expert would recognise either as requiring cable or wireless. Depending on the coniditon of computer structures requesting to establish a network structure is acheivable. Refer with a computer networkin technician that would evaluate the devices at the location to ascertain the requisite structures to establish networking telecommunications. For example, refering with an expert ascertains that the computer requires modems to capture the signals or modern devices require a miniature adaptor device attacked to the computer.

Use an Ethernet cable between the network-port on your computer and one of the LAN ports on your wireless router.

Start Internet Explorer.
Connect to the web-server "inside" the router.
Run the "Wireless Networking Setup Wizard", to establish an SSID, choose an encryption-level (use 'WPA'), and to establish a password/pass-phrase/network-key.

Use the SSID and the password to connect to your newly-configured wireless network.

Hello,

Check the "TCP end timeout" setting. You can find in Policy -> Global
Properties -> Stateful Inspestion. FW-1 will take a connection out of
its established connections table after two FIN packets (one from each
party) or a RST packet + the time defined in this setting.

Have a great day,
