Network Setup

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.

On 30 August 2016 the ADSL2+ Annex M High Speed profile gives Up/Down Sync Speed 1792500/199520000 SNR Margin 6.0 dB/6.30 dB Line Attenuation 13.0 dB/21.5 dB. Earlier Speediest reported 16.44/1.45/25ms. When it was unstable with dropouts every 30 minutes or so observed during office hours used a ADSL2+ Annex M Standard profile Nwhich 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.

After any restart of the router the Switch in the Hall and the access point in the Bari Room should be power cycled or reset

Fault 11459608

  • Experiencing frequent dropouts
  • Modem is not responding on HTTP server
  • Replaced on Friday 12th with spare after too many dropouts around 1pm, unable to send email
  • Replaced on Monday 15th ? with another spare, Billion 5200
  • At 2:43 pm on Tuesday 16th change profile to ADSL2+ Very High Reliability - 16.4 Down, 1 Up
  • Will change cable between modem and wall at 8pm and check dropouts
    • Cable changed at 6pm, still dropping out
  • Rang Internode on Wednesday at 3pm, Dropouts are continuing.
  • Next step is to ring Internode Support from site so they can test with the modem plugged in and out to determine what to do.
  • Rang 2:58pm on the 25th. Service had a Port Swap, yesterday (? 2016-08-24 13:35:49), should consider closed, may remove spare equipment, profile back on ADSL2+ Annex M High Speed.

Dropouts late Feb 2018

With the new FritzBox! getting some dropouts recorded, up to 3 events in one day. Prior to changing the internet profile

  • Using "ADSL2+ Annex M High Speed"
  • Not recoverable errors about 0.22 per minute after 1 day

Router Setup

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

  • Firmware 6.21 or better to support IPV6
  • Quick Start
    • Internet User@internode.on.net and Password (Select ipv6 option in Internode user settings)
    • PPOE (Naked service)
    • Wireless Network:
      • Turned on
      • Non-default SSID
      • Use Channel 11
      • WPA2-PSK and password set
    • VOIP disabled
  • Configuration->LAN->DHCP Server->Fixed Host to provide static IP for the photocopier (192.168.1.200 28:84:fa:3a3b:c7)
  • System->Timezone is Adelaide
  • NTP Server 1 set to ntp.internode.on.net
  • Set a mail alert (Configuratoin->System) using Internode SMTP Server and notify for Failover/Fallback and WAN IP Change (last four boxes all the same email) if available
  • Set a non-default administration password
  • Turn on logging at Debugging level
  • </strike>Experimental Configuration->WAN->ADLS Mode->Connect Mode AnnexM2+/M2 Fallback</strike>Don't do this it restricts bucket usage and lowers bandwidth. It doesn't speed up modem training as you might expect

Lan Extensionm - Bari School

The Wired/Wireless Lan is extended by a pair of NP285 Ethernet over Power plugs to the Bari School Room. A Time Capsule using the same subnet as the rest of the network provides wireless and wired access for the Eastern end of the building. This also gives IPv6 connectivity. Testing with speedtest.net gives 32ms/14.82Mbs/1.92MBs to the Bari Room. To the music room, very slow, unreliable along Southern wall, about 0.5-1MBs (Megabit/second) to the Northern Wall. On the Western side of the choir robing area about 1.5MBs.

These are fairly ancient devices and require a specific program from Netcomm and Windows 98Se, Windows me, Windows 2000, or Windows XP. Once you've got this organised

  • Install the configuration Utility
  • Set the privacy password the same for all devices on the network

Time Capsule Setup

This device (2TB, Serial C86K500SDM73) replaced the Linksys Router, key points in setup

  • Network is Bridge so as to allow roaming within the building between access points
  • Suffix 5GHz to the network name on 5GHz (Under Wireless Options)
  • 2.4 GHz channel 1, 5 GHz Automatic (Under Wireless Options)
  • Turn on IpV6 automatic
  • Turn on IpV6 connection sharing

Wired

Wired access is available in the workroom, hall (south eastern end only) and reception area. The hall has a Linksys SD208 switch which according to reports has odd polarity in its Ethernet connection. For devices that are fussy such as an Intel 82566DM Gigabit (Intel 82573V Gigabit and Intel Pro 100V dont mind) there is a Linksys WRT54G used as switch only to deal with the electrical issues. This should all probably be replaced by a more modern 8 port switch to avoid the clutter and extra power etc.

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.

File sharing between Windows and Mac Lion computers

The setup below should share files on the Windows computer with Authenticated users from a Macintosh

Sharing from a Window 7 computer

  1. Make sure the computer has a Workgroup name and a computer name
  2. Make sure you can log into the Windows computer
  3. Open the Network and Sharing Center in control panel
    1. Select Choose Homegroup and Sharing options
    2. Select Change advanced sharing settings
      1. Turn on Network Discovery
      2. Turn on File and Printer Sharing
      3. Turn on Public Folder Sharing
      4. Turn on Password Protected Sharing
  4. On the Macintosh Open the Finder and wait a moment or two and the computer name should appear. Unfortunately this does not work for MacOsX 10.5.8
  5. Connect to the Windows computer using your Windows credentials

Sharing from a Windows XP computer

  1. Log on to the Windows Computer
  2. Select the Shared Documents Folder
  3. Run the network and Sharing wizard, this will require a restart
  4. When restarted check Allow network users to change my files so that editing of files from the Macintosh is possible.
  5. Under folder options deselect Use simple file sharing to make the Security tab visible
  6. In the security tab for Shared folders remove all (Read & Execute, List file contents, Read) rights for Everyone. This will cause Everyone to disappear from the groups lists and only authenticated access will work.
  7. On the Macintosh in a Finder window the computer should appear. You will need to connect as an authenticated user and should then be able to access files.
