Vigor Router FAQ

Setup for 'BeThere' or 'O2' (UK ISPs)

 

1. Connect the power adaptor to the Vigor 120 and turn it on.
2. Connect an Ethernet cable directly from a PC to the Vigor 120.
3. After a few moments, the PC should get an IP address (Most likely 192.168.2.10)
4. In your web browser, access the Vigor 120's web interface at http://192.168.2.1 (192.168.1.1 if you are using a Vigor100/220)
5. Go to the Internet Access menu and then click on the MPoA tab.
6. Check that the settings are correct (VPI 0 /VCI 101/1483 Bridged LLC)
7. You must now click the 'Enable' button on the MPoA tab.
8. If you wish, you can also set the modulation mode (e.g. ADSL2+) but this is not necessary, it just makes it re-connect quicker.
9. Do not select Annex M unless you definitely have that from your ISP.
10. If you are unsure, leave the modulation at AUTO.
11. Click OK and the Vigor 120 will save the settings and reboot.
12. Connect the ADSL line cable to the Vigor 120.
13. After a short while* your PC should then get a new IP address which will be the public IP address allocated by your ISP. If your ISP has allocated you with a fixed IP Address or a range of IP Addresses you should manually set this on the PC using the details they have provided for IP, Subnet Mask, G/W and DNS as the ISP will only allocate IP Addresses automatically to dynamic IP connections.
14. You can now access the Internet normally

Additional Setup for MPoA

Some ISPs using MPoA send 'rogue' (invalid) ARP messages to the modem. This will prevent data from flowing to the Internet; the router will show you as online, with an IP address. If this occurs, you will need to telnet to the router (not the modem) and issue the command ip arp accept 1. This is available on the Vigor29XX series routers.

Troubleshooting

Setting up Internet access via a Vigor120 modem is a straightforward process so hopefully everything should go smoothly. However, below are a few tips that cover some possibilities:

1. An important item to note is that for the PPPoE connection a "Service Name" should never be entered. If you have this field in the configuration of the router or computer that you're using then make sure that it is left empty.
   
2. Check to see if the ISP is using MPoA or PPPoA. The configuration on the Vigor120 modem differs depending on the ISP connection type. See the setup guide above for the configuration for MPoA lines.
   
3. If your Vigor 29xx series router establishes a connection while the Vigor120 is in MPoA bridge mode but it is not possible to access Internet then you will need to reconfigure the router to accept the arp requests originating from the Vigor120. Telnet in to the Vigor 2950, type the command "ip arp accept 1" and reboot the router.

This information is for the Vigor3100 series routers, used on SDSL lines. The Vigor3100 series will not operate on ADSL lines. Check with your ISP for any variations on SDSL setup parameters as these can vary between ISPs, especially when they are using their own DSLAMS as part of LLU. These are the most typical settings:
