Internet Access

Internet access uses a Naked Extreme ADSL service from Internode. Typical sync speed for non-AnnexM is 21902500/1270000, SNR 6dB/6dB, Attenuation 23.5dB/9dB (Down/Up). If the speed drops, check the cable from the patch panel to the modem, the ADSL setup is quite picky and you should check the sync speed when any work is done on or near the wiring. Use only the "High Speed ADSL2+" profile as due to the proximity of the exchange using a higher speed profile will reduce the speed due to reflections! Speedtest.net will report 18.05MBsec/1.03MBsec/30mSec, using the Internode mirror test files of more than 100Meg will give a 2.13MByte/sec download.

The ADSL2+ Annex M High Speed profile gives Up/Down Sync Speed 2509200/19644100 SNR Margin 6.0 dB/6.35 dB Line Attenuation 12.5 dB/21.5 dB but is unstable with dropouts every 30 minutes or so observed during office hours. Instead us a ADSL2+ Annex M Standard profile which gives Up/Down Sync Speed 2346200/18260100 SNR Margin 11.0 dB/9.05 dB Line Attenuation 12.5 dB/21.5 dB. Speedtest reports 25ms/15.25Mbps/1.89Mbps on this profile and no dropouts seen after five days.

Router Setup

The Billion 7404VGOX router has the following non-default settings:

• Firmware 6.21 or better to support IPV6
• Router administration password changed
• Internet User@internode.on.net and Password (Select ipv6 option in Internode user settings)
• PPOE (Naked service)
• DHCP to provide static IP for the photocopier
• Wireless Network:
  • Turned on
  • Non-default SSID
  • Use Channel 11
  • WPA2-PSK and password set
• VOIP disabled
• Firewall setup...

Lan Extension

The Wired/Wireless Lan is extended by a pair of NP285 Ethernet over Power plugs to the Bari School Room. A Linksys WRT54G v7 router with firmware 7.00.6 is used to provide another Wireless access point on Channel 1 using the same subnet as the rest of the network. This also gives ipV6 connectivity.

Setup as a bridge

1. Set up from factory reset with the same wireless settings as other routers
2. Set wireless to channel 1
3. Alter router (Basic setup page) to have a static IP within the range of the other router
   • a local IP address of 192.168.1.251
   • subnet mask of 255.255.255.0
   • a gateway of the other routers IP address (not present in this version of router firmware)
   • Disable DHCP in the router
4. Save and reboot the router
5. Connect the incoming LAN from the NP285 to Ethernet Port 1
6. Manage the router from the local IP address specified above.

Wired

Wired access is available in the workroom, hall (south eastern end only) and reception area. This uses a Linksys WRT54G Version 2. The following MAC addresses should be barred access Saturdays 1-5pm to suit the Bari Community School

1. 00:08:C7:25:4C:58
2. 00:02:B3:20:AB:BF
3. 00:02:B3:21:33:AD
4. 00:c0:df:11:d3:10
5. 00:04:5a:6a:73:e7

Wireless

A wireless network provides good coverage of the office area, tank rooms, hall and kitchen downstairs. The coverage in the Leaver lounge is usable. There is no useable coverage beyond the doors from the Leaver lounge to the stairway. Coverage is fair in most of the church upstairs, with no usable coverage beyond the doors leading to the Stanley St entrance or the flower preparation area, (i.e. west of the organ.)

The wireless network is B & G.
