IGRS: Frequently Asked Questions

Problem Solving about IGRS:

Frequently Asked Questions (FAQ):

• Q: What is wireless interconnection (wireless network)?
  
  A: Wireless interconnection refers to the interconnection between wireless devices such as notebooks. Generally, notebooks are installed with IEEE 802.11 a/b/g wireless network adapters. IEEE 802.11 is a wireless communication protocol as follows:
  
     2.4GHz/5GHz radio waves for transferring data; 54 Mbps of data rates of 802.11a/g;
  
     Up to hundred meters of transmission range (150-300 meters outdoor and 30-50 meters indoor);
  
     Two modes: Access Point (AP) mode and Peer-to-Peer (Ad-hoc) mode;
  
  
  
• Q: What is the difference between Access Point (AP) mode and Peer-to-Peer mode?
  
  A: AP mode enables connection between wireless and wired networks, so that a notebook is able to access Internet wirelessly through an AP. P2P mode enables wireless interconnection among multiple notebooks anywhere at any time without using other device. Click AnyComm "IGRS Mobile Network (Multi Users Wireless Interconnection)" to enter this mode. The two modes are inter-complementary.
  
  
  
• Q: Does AnyComm realize interconnection only via wireless networks?
  
  A: Via either wireless network or wired LAN. When using a wireless network, you may either use "IGRS Mobile Network (Multi Users Wireless Interconnection)" for P2P interconnection or use AP for interconnection. In the case of interconnection via a wired LAN, only two computers need to be connected with network cables.
  
  
  
• Q: Can AnyComm be connected to AP wireless network?
  
  A: Yes. For an AP-based wireless network, you may use either convenient "Network Configuration Wizard" or multi-functional "Advanced Configuration" in "Intelligent Network Configuration".
  
  
  
• Q: Why does my WINDOWS Wireless Configuration not work?
  
  A: You can choose to use only one between Intelligent Network Configuration and WINDOWS Wireless Configuration. If you need to use WINDOWS Wireless Configuration, please exit from Intelligent Network Configuration. Right-click "Intelligent Network Configuration" icon ,in WINDOWS System Tray, and select "Exit".
  
  
  
• Q: How to connect IGRS mobile network?
  
  A: Run "IGRS Mobile Network (Multi Users Wireless Interconnection)" in "AnyComm Wireless Config" in the Home to directly switch to IGRS mobile network.
  
  
  
• Q: How to configure Internet connection sharing?
  
  A: Run "Internet connection sharing" in "AnyComm Wireless Config" in the Home, or select "Interconnect Multiple Computers and Access Internet via One Computer (Internet connection sharing)" under Manual Configuration in "Network Configuration Wizard" to configure Internet connection sharing.
  Note: If you use CDMA card for Internet connection, you have to manually start CDMA network dial-up in "View Network Status" screen after applying this shared profile.
  
  
  
• Q: what is IGRS AP?
  
  A: IGRS AP is a short name for a Lenovo’s wireless router which SSID is "igrs-ap" or "Lenovonetworks".
      "IGRS AnyComm Intelligent Network Config" helps you to dial up through ADSL (or other dial-up community broadband) without entering IGRS AP configuration screen (or using management software).
  
  
  
• Q: How to use Network Roaming?
  
  A: After you have installed IGRS AnyComm, "Intelligent Network Config" will automatically enable "Roaming". If you want to disable roaming, select "Network Roaming" in the right-click context menu or double-click "Disable Roaming" in "AnyComm Wireless Config" in IGRS AnyComm Home.
      Network Roaming function allows automatic connection to another configured WAPwhen the wireless network you are using is disconnected. If you have a CDMA card, this roaming function will also use CDMA card for Internet connection if no other available WAP is found. After your wireless network restores connection, CDMA card will be disconnected automatically.
  
  
  
• Q: How to use IGRS AP for Internet connection?
  
  A: In "AnyComm Intelligent Network Config", IGRS AP and Internet connection sharing can not be configured in a same profile. If you need to access Internet via shared IGRS AP, you may set the "Adapter connected to Internet" as wireless network connection and select "igrs-ap" or "lenovonetworks" as the SSID.
  
  
  
• Q: Why Do I always fail to connect CDMA with "Intelligent Network Config"?
  
  A: For the first step, you need "Palm Broadband" service provision if you plan to use CDMA card. You have to apply to China Unicom for the provision of such service.
      If "Palm Broadband" service has been opened to you, please ensure that the sufficient prepayment has been paid into the UIM card.
  
  
  
• Q: When switching profiles using "AnyComm Intelligent Network Configuration" tool, why the connected network is not that configured one in the profile though a prompt of "switching successful" displays?
  
  A: Sometimes AnyComm Intelligent Network Configuration would prompt that profile-switching fails, or network has not switched actually though it displays that switching is completed successfully. This is because AnyComm Intelligent Network Configuration can not run simultaneously with WINDOWS wireless configuration. However, some other wireless network configuration tools that have been installed in your computer would open WINDOWS Wireless Configuration so that AnyComm Intelligent Network Configuration fails in configuring other wireless network adapters.
      Solution: Uninstall other wireless network configuration tools and restart "AnyComm Intelligent Network Configuration".
  
  
  
• Q: If I have installed a firewall, do I need to enable a corresponding port for IGRS AnyComm?
  
  A: As IGRS AnyComm will be used in networks, a firewall certainly affects proper operation of AnyComm.
  
      We suggest you to use window firewall, for the IGRS AnyComm has released the windows firewll access restriction for corresponding procedure when it is installed.
  
      If you are using another firewall (e.g. Kingsoft Build) and AnyComm fails to work properly while the firewall is running, please manually release the restriction to AnyComm in the firewall software.
      The firewall must be configured to allow following AnyComm programs to access network
      You need to search in the new folder if you have changed the path for installation (e.g. you have installed “IGRS AnyComm" under C:\Program Files\Lenovo\).
  
     C:\Windows\System32\Igrssvcs.exe
     C:\Program Files\Lenovo\IGRS\IGRS.exe
     C:\Program Files\Lenovo\IGRS EasyShare\IgrsPortal.exe
     C:\Program Files\Lenovo\IGRS EasyShare\FileShare.exe
     C:\Program Files\Lenovo\IGRS EasyShare\IgrsFile.exe
     C:\Program Files\Lenovo\IGRS EasyShare\Games\MaJiang.exe
      Some firewall software will automatically pop-up a dialogue box asking whether to allow a certain program to access the network. Select "Yes" for the above programs.
  
      Where the security level of a firewall is set at "Med" or "High" which causes improper operation of AnyComm, enable the local and remote access authorities of following ports in the firewall software:
      UDP port: 1900,3880,6555.
      TCP port: 3880,5759-5768.
      For specific settings of a firewall, carefully read the Help in corresponding firewall software.
  
  
  
• Q: Why am I unable to access Internet via shared connection after installing a firewall?
  
  A: This might because you have set the security of the firewall at excessive high level. You are suggested to lower the security level of your firewall, or refer to the recommendations of WINDOWS Help and Support Center for resetting the firewall software.
