![Wireless Settings 37The DHCP Clients List provides details on the devices that are connected to the LAN. The list is only created when the Access Point is set up as a DHCP server. For each device that is connected to the LAN, the IP address, Host Name, MAC address and Client Type of that device is displayed. As you connect more devices, the client list will grow to a maximum number of clients. The Release button allows the lease time for the IP address that has been issued to a device to be cleared. The lease time is set at 12 hours. If a PC has been switched off, using the Release button would allow the 12 hour lease time to be cleared. The IP address would then be available for another device if there were no other IP addresses available. As the IP address is fixed to a MAC address, then each particular computer will normally be issued with the same IP address. The only time that a PC will get a different IP address is if the DHCP server has run out of IP addresses.Wireless SettingsTo improve the security of your wireless network, 3Com recommends that you:1. Change the SSID from its default value - see page 392. Enable Encryption - see page 403. Enable Connection Control - see page 42](https://usermanual.wiki/Accton-Technology/3CRWE41196.User-Guide-Part-2/User-Guide-324492-Page-17.png)
![38 CHAPTER 4: ACCESS POINT CONFIGURATIONConfiguration Figure 26 Configuration ScreenEnable Wireless NetworkingAllows you to enable/disable the wireless section of your LAN. When disabled, no wireless PCs can gain access to your Wired or Wireless LAN through this Access Point.Channel SelectionThe Channel Selector allows you to specify which Channel the Access Point will transmit and receive on. If someone else nearby is using the same Channel as you, there will be a reduction in the performance of your network. If this seems to be the case, you should select a different channel number. Usually the Wireless computers will scan to find the correct channel, but if they don't you must configure them to use the same Channel number as the Access Point.Valid channels are country dependent. See “Channels” on page 83 for a list of channels approved by each country.Clear Channel Select allows the Access Point to automatically select the optimum channel when first powered on.](https://usermanual.wiki/Accton-Technology/3CRWE41196.User-Guide-Part-2/User-Guide-324492-Page-18.png)
![Wireless Settings 39Service Area Name/SSIDThis allows you to name your Wireless network. The field will accept any alphanumeric string and has a maximum length of 32 characters. Your Wireless computers must be configured with exactly the same name or you will not establish a connection. The Service Area Name may also be referred to as "ESSID" depending on your networking vendor. By default the Access Point uses the name "3Com". 3Com recommends that you change the default name.In order that your wireless computers can connect to the Access Point, you must:■Use Infrastructure Mode not Adhoc Mode.■Have the same Service Area Name as the Access Point.■Use the same encryption type and keys as the Access Point.■Ensure that the PC is included in the authorized Wireless PCs list if Connection Control is enabled. See page 42.Disable Broadcast SSIDThis feature can be used to improve the security of your wireless network. When the tickbox is checked, the Access Point will not broadcast the Service Area Name/SSID of your wireless network. This will prevent unauthorized clients from detecting your SSID and attempting to connect to your network.If you have a wireless client that can detect all the available SSIDs in your area, your client will not list the Access Point SSID when this feature is enabled.3Com recommends that you install your wireless network with this feature disabled and then enable it once you have set up the Access Point and wireless clients.Access Point NameThis option allows you to name the Access Point. The field accepts any alphanumeric string upto a maximum of 32 characters. This option is useful if you have several Access Point units and want to be able to easily identify them. For example, you may name them Marketing, Research, Admin.](https://usermanual.wiki/Accton-Technology/3CRWE41196.User-Guide-Part-2/User-Guide-324492-Page-19.png)
![40 CHAPTER 4: ACCESS POINT CONFIGURATIONEncryption Figure 27 Encryption ScreenWired Equivalent Privacy or WEP allows you to encrypt the traffic between your Wireless PC and the Access Point. It is important to remember that with WEP disabled anyone with a Wireless PC can eavesdrop on your network. 3Com recommends that you get the network working with WEP disabled first and then enable it as the last step. This will simplify setting up your network. If you enable WEP on the Access Point, you must reconfigure your wireless PCs to use exactly the same Encryption Type and Keys otherwise the devices will not understand each other. WEP is for securing data transmitted through wireless communications between the Access Point and it's wireless clients. Enabling WEP has no security effect on data transmitted through wired (Ethernet) connections or through your connections to the Internet.Wireless Encryption TypeThere are two levels of encryption available, 64 bit (sometimes referred to as 40 bit) and 128 bit. 128 bit will result in a higher level of security, but may cause a slight decrease in performance. Use the Wireless Encryption Type box to select the desired level.](https://usermanual.wiki/Accton-Technology/3CRWE41196.User-Guide-Part-2/User-Guide-324492-Page-20.png)
![Wireless Settings 41Encryption KeysFigure 28 Encryption Keys ScreenA Key is a hexadecimal (0-9, A-F) number used to encrypt and decrypt the data. There can be up to 4 keys and each key can be as long as 26 digits. The Access Point also offers a number of methods for converting plain text into hex keys. The text is much easier to remember than hex keys but it relies on your wireless adapters also supporting this feature. Different manufacturers have developed different ways of converting plain text and so interoperability is not guaranteed. If you are experiencing difficulty, the Manual Hex Key method is supported by most vendors. There are four methods available to generate the encryption keys:■Manual Key Entry - This method allows you to manually enter hex keys. Virtually all manufacturers support this scheme. Enter a two digit hexadecimal number in every box. Hexadecimal numbers are formed from 0-9 and A-F. ■3Com Encryption String - This method is supported by 3Com Wireless products. The string can contain any alphanumeric characters and must be between 6 and 30 characters long. A single string will automatically generate 4 unique keys for 64 or 128 bit WEP. ■ASCII - This method is supported by some adapter cards running under Windows XP. The string must be exactly 5 characters for 64 bit](https://usermanual.wiki/Accton-Technology/3CRWE41196.User-Guide-Part-2/User-Guide-324492-Page-21.png)
![42 CHAPTER 4: ACCESS POINT CONFIGURATIONWEP and 13 characters for 128 bit WEP. You must enter a separate string for each of the 4 Keys. You can leave a string blank provided this Key is not selected as the Active Transmit Key.■Passphrase - This is another common method and similar to the 3Com Encryption string. In 64 bit WEP, the passphrase will generate 4 different keys. However, in 128 bit WEP, this method only generates 1 key which is replicated for all 4 keys. The passphrase can be up to 31 characters long and may contain any alphanumeric characters.Select from the drop down list the key generation method you wish to use. If you have other wireless products choose the scheme that is compatible with these, then enter the appropriate information.If you encounter any difficulty when you enable WEP ensure that you check that each key on your wireless computer is exactly the same as each key on your Access Point. In other words, Key number 1 on the Wireless computer must have the same Hex number as Key number 1 on the Access Point, Key 2 on the Wireless computer must match Key 2 on the Access Point and so on.The Active Transmit Key selects which of the 4 Keys the Access Point uses when it transmits. You can change the selected key periodically to increase the security of your network.Some wireless adapters have only one key available on their WEP configuration page. If this is the case ensure it is the same as Key 1 on the Access Point and that it is selected as the active transmit key.Connection Control This screen allows you to determine if all Wireless PCs or just authorised Wireless PCs can use the Access Point. Select Connection Control to display the screen shown in Figure 29.](https://usermanual.wiki/Accton-Technology/3CRWE41196.User-Guide-Part-2/User-Guide-324492-Page-22.png)
![Wireless Settings 43Figure 29 Connection Control ScreenA higher level of security can be achieved for your wireless network if you use both encryption and you specify only certain wireless computers can connect to the Access Point. By default, any wireless computer that has the same Service Area Name/SSID, channel and encryption settings as the Access Point can connect to it. Select Only Authorised Wireless PCs can connect to the Access Point to enable and configure this feature.If you enable this feature from a Wireless PC, it will automatically be added to the Authorised Wireless PC list.Authorised Wireless PCsFigure 30 Connection Control Detail Screen](https://usermanual.wiki/Accton-Technology/3CRWE41196.User-Guide-Part-2/User-Guide-324492-Page-23.png)
