I am trying my best to assist my nextdoor neighbour set up his AirPort Extreme wi-fi router to work with his new fibre-optic broadband supplier, which is a UK telecoms company called TalkTalk.
When the fibre optic service was installed in his house the other day, through a British Telecom Openreach modem, I assumed that we could just plug the Ethernet cable from that into his AEBS using his old settings. (He hasn't changed companies, just upgraded to a fibre-optic service with the same company.)
Of course, things are never that simple... Basically it wouldn't work, and TalkTalk are less than helpful. ("We provide you with a router, we will only support that router.")
I've done some research on TalkTalk discussion groups, and the best advice I can find is a post which seems at first to provide all the answers, but unfortunately relates to an earlier version of AirPort Utility than that which is on both our Macs.
I copy the post below verbatim. Can anybody with knowledge of the difference between the different versions of AirPort Utility possibly assist in translating the instructions in the post into useable instructions for AU version 6.3.2 please...? [I fell at fence '6 - Select 'Ethernet'.]
1 - On your Mac go to Applications > Utility > Airport Utility and launch it
2 - Highlight your Airport Extreme (or Time Capsule/Express)
3 - Now go to Manual Setup and wait while the information is gathered
4 - By default you go to Airport and Summary click on the Internet icon at the top
5 - Internet Connection is the first item
6 - Under Connect using: select 'Ethernet'
7 - Under Connection Sharing: select 'Share a public IP address'
8 - Now click on TCP/IP
9 - First off 'Configure IPv4 select 'Using DHCP' *You may also wish to enter the DNS server(s) using something other than the default like OpenDNS. Enter them here
10 - Now go to the next heading 'DHCP' and click on it
11 - First is DHCP Beginning Address: select your choice. Most choose 192.168.X.X (My preference is 192.168.0.150)
12 - Now go to DHCP Ending Address: and enter your choice. Mine is 192.168.0.199
13 - DHCP Lease I choose 1 day
14 - If you have any IP reservations enter them now
15 - Next is the 'NAT' Heading: Here you can Configure Port Mappings. Call it Port Forwarding if you like, most other manufacturers do!
16 - Now click on UPDATE at the bottom
The Extreme or Time Capsule will reboot with your new settings and if you are plugged into the Openreach modem you will be connected to the internet using the Airport Extreme. Don't worry if the IP Address shows a curious number 169 etc, this is normal and will change when the Airport and modem have 'settled down'. I thought this was a problem initially, but closing the Airport Utility and opening it again showed that the Airport Summary page had;
Connected Using: Ethernet
IP Address: had changed from the 169 number to 2.103.xxx.xx my IP address.
I'd like to thank Anthony in the Northern Ireland Talktalk Fibre Help Centre for putting me onto the right track though nobody there knows anything about Macs!
If they read this please use it as a template!
Talktalk differs from BT Infinity in that BT use PPPoE with a user name and Talktalk use Ethernet, a Service called TR069_INTERNET amd connection called ROUTE and no user name is needed which is compatible with the Airport Extreme units.
Thanks in advance.
