MB6800 Frequently Asked Questions

When I enter a URL or IP address, I get a time-out error or I am
prompted to retry.
• Check if other PCs work. If they do, ensure that your workstation’s IP settings are correct
(IP Address, Subnet Mask, Default Gateway, and DNS). Restart the computer that is
having a problem.
• If the PCs are configured correctly, but still not working, check MB6800. Ensure that it is
connected and powered on. Connect to it and check its settings. (If you cannot connect to
it, check the LAN and power connections.)
• If MB6800 is configured correctly, check your Internet connection (WWAN card) to see if
it is working correctly.
• Manually configure the TCP/IP settings with a DNS address provided by your ISP.
• Make sure that your browser is set to connect directly and that any dial-up is disabled.
For Internet Explorer, click Tools, Internet Options, and then the Connection tab. Make
sure that Internet Explorer is set to Never dial a connection. For Netscape Navigator, click
Edit, Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to
Direct connection to the Internet.
Frequently Asked Questions

What is the maximum number of IP addresses that MB6800 will support?
MB6800 will support up to 253 IP addresses.

Is IPSec Pass-Through supported by MB6800?
Yes, it is a built-in feature that MB6800 automatically enables.
Does MB6800 support IPX or AppleTalk?
No. TCP/IP is the only protocol supported.
What is Network Address Translation and what is it used for?
Network Address Translation (NAT) translates multiple IP addresses on the private LAN
to one public address that is sent out to the Internet. This adds a level of security since the
address of a PC connected to the private LAN is never transmitted on the Internet.
Furthermore, NAT allows MB6800 to be used with low cost Internet accounts. The user
may have many private addresses behind this single address provided by the ISP.

Does MB6800 support any operating system other than Windows 98, Windows
Millennium, Windows 2000, or Windows XP?
Yes.

Does MB6800 support ICQ send file?
Yes, with the following fix: click ICQ menu -> preference -> connections tab->, and check I
am behind a firewall or proxy. Then set the firewall time-out to 80 seconds in the firewall
setting. The Internet user can then send a file to a user behind MB6800.

Can multiple gamers on the LAN get on one game server and play simultaneously
with just one public IP address?
It depends on which network game or what kind of game server you are using. It will work
if the game server supports multi-user with one public IP address.

Which browsers does MB6800 support?
MB6800 supports Internet Explorer 4.0, Netscape 4.0, Mozilla and Safari which mainly
used in Macintosh.

I am not able to get the web configuration screen for MB6800. What can I do?
You may have to remove the proxy settings on your Internet browser, e.g., Netscape
Navigator or Internet Explorer. Or remove the dial-up settings on your browser. Check
with your browser documentation, and make sure that your browser is set to connect
directly and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options,
then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection.
For Netscape Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that
Netscape Navigator is set to Direct connection to the Internet.

Does MB6800 pass PPTP packets or actively route PPTP sessions?
MB6800 allows PPTP packets to pass through.

Is MB6800 cross-platform compatible?
Any platform that supports Ethernet and TCP/IP is compatible with MB6800.

Can MB6800 act as my DHCP server?
Yes. MB6800 has DHCP server software built-in.

What is the IEEE 802.11g standard?
It is one of the IEEE standards for wireless networks. The 802.11g standards allow
wireless networking hardware from different manufacturers to communicate, provided that
the hardware complies with the 802.11g standards. The 802.11g standards state a
maximum data transfer rate of 54Mbps and an operating frequency of 2.4GHz. The
802.11g is downward compatible with 802.11b.

What IEEE 802.11b features are supported?
The product supports the following IEEE 802.11b functions:
• CSMA/CA plus Acknowledge protocol
• Multi-Channel Roaming
• Automatic Rate Selection
• RTS/CTS feature
• Fragmentation
• Power Management
Will the information be intercepted while it is being transmitted through the air?
WLAN features two-fold protection in security. On the hardware side, as with Direct
Sequence Spread Spectrum technology, it has the inherent security feature of scrambling.
On the software side, WLAN offers the encryption function (WEP or WPA) to enhance
security and access control.

What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 64-bit or 128-bit
shared key algorithm, as described in the IEEE 802.11 standard.

What is WPA-PSK?
WPA-PSK means Wi-Fi Protected Access - Pre-Shared Key. It is an enhanced wireless
encryption standards defined by the WiFi Alliances.

What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned by the
manufacturer to any Ethernet networking device, such as a network adapter, that allows
the network to identify it at the hardware level. For all practical purposes, this number is
usually permanent. Unlike IP addresses, which can change every time a computer logs
onto the network, the MAC address of a device stays the same making it a valuable
identifier for the network.

How do I reset MB6800 to factory default?
When MB6800 is working in normal status, press and hold the RELOAD button for about
20 seconds, until all the indicator lights turn off. Then release RELOAD button, press the
RESET button to set up the device again. This will reset MB6800 to its default settings.
How do I resolve issues with signal loss?
There is no way to know the exact range of your wireless network without testing. Every
obstacle placed between MB6800 and a wireless PC will create signal loss. Lead glass,
metal, concrete floors, water and walls will inhibit the signal and reduce range. Start with
MB6800 and your wireless PC in the same room and move it away in small increments to
determine the maximum range in your environment. You may also try using different
channels, as this may eliminate interference affecting only one channel.
I have excellent signal strength, but I cannot see my network.
WEP or WPA-PSK is probably enabled on MB6800, but not on your wireless client. Verify
that the same keys are being used on all nodes of your wireless network.
How many channels/frequencies are available with MB6800?
There are eleven available channels, ranging from 1 to 11 (in North America).
