Appendix A Troubleshooting A This Appendix covers the most likely problems and their solutions. Overview This chapter covers some common problems that may be encountered while using the Wireless ADSL2/2+ Modem Router and some possible solutions to them. If you follow the suggested steps and the Wireless ADSL2/2+ Modem Router still does not function properly, contact your dealer for further advice. General Problems Problem 1: Can't connect to the Wireless ADSL2/2+ Modem Router to configure it.
Wireless ADSL2/2+ Modem Router User Guide • Check the Wireless ADSL2/2+ Modem Router's status screen to see if it is working correctly. Problem 2: Some applications do not run properly when using the Wireless ADSL2/2+ Modem Router. Solution 2: The Wireless ADSL2/2+ Modem Router processes the data passing through it, so it is not transparent. For incoming connections, you must use the Virtual Server or Firewall Rules to specify the PC which will receive the incoming traffic.
Appendix A - Troubleshooting show a marked improvement. • Radio Interference Other devices may be causing interference. You can experiment by switching other devices Off, and see if this helps. Any "noisy" devices should be shielded or relocated. • RF Shielding Your environment may tend to block transmission between the wireless stations. This will mean high access speed is only possible when close to the Wireless ADSL2/2+ Modem Router.
Appendix B About Wireless LANs B This Appendix provides some background information about using Wireless LANs (WLANs). Modes Wireless LANs can work in either of two (2) modes: • Ad-hoc • Infrastructure Ad-hoc Mode Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Stations (e.g. notebook PCs with wireless cards) communicate directly with each other. Infrastructure Mode In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations (e.g.
Appendix B - About Wireless LANs performance. This capability is called Roaming. (Access Points do not have or require Roaming capabilities.) Channels The Wireless Channel sets the radio frequency used for communication. • Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channels are available.
Wireless ADSL2/2+ Modem Router User Guide Encryption The same encryption method must be used. The most common encryption method is TKIP. Another widelysupported method is AES. Wireless LAN Configuration To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point must use the same settings, as follows: Mode On client Wireless Stations, the mode must be set to "Infrastructure". (The Access Point is always in "Infrastructure" mode.
Appendix C About VPNs C Overview A VPN (Virtual Private Network) provides a secure connection between 2 points, over an insecure network - typically the Internet. This secure connection is called a VPN Tunnel. There are many standards and protocols for VPNs. The standard implemented in the Wireless ADSL2/2+ Modem Router is IPSec. IPSec IPSec is a near-ubiquitous VPN security standard, designed for use with TCP/IP networks.
Wireless ADSL2/2+ Modem Router User Guide Because the IKE and IPsec connections are separate, they have different SAs (security associations). Policies VPN configuration settings are stored in Policies. Note that different vendors use different terms. Generally, the terms "VPN Policy", "IPSec Policy", and "IPSec Proposal" have the same meaning. However, some vendors separate IKE Policies (Phase 1 parameters) from IPSec Policies (Phase 2 parameters).
Appendix C - About VPNs Common VPN Situations VPN Pass-through Figure 76: VPN Pass-through Here, a PC on the LAN behind the Router/Gateway is using VPN software, but the Router/Gateway is NOT acting as a VPN endpoint. It is only allowing the VPN connection. • The PC software can use any VPN protocol supported by the remote VPN. • The remote VPN Server must support client PCs which are behind a NAT router, and so have an IP address which is not valid on the Internet.
Wireless ADSL2/2+ Modem Router User Guide Connecting 2 LANs via VPN Figure 78: Connecting 2 VPN Gateways This allows two (2) LANs to be connected. PCs on each endpoint gain secure access to the remote LAN. • The 2 LANs MUST use different IP address ranges. • The VPN Policies at each end determine when a VPN tunnel will be established, and what systems on the remote LAN can be accessed once the VPN connection is established. • It is possible to have simultaneous VPN connections to many remote sites.
