Contents > Singtel v5.29 firmware installation:
+ WPA-PSK2 wireless security. Wireless power level menu (25 - 100mW). Wireless MAC filtering. Enhanced services. Immune to BT v6.w firmware upgrade but could be susceptible to future Singtel FW upgrade.
- Not recommended for long or low speed lines.
Suitable for Single and Dual SSID models. This firmware cannot be used to downgrade hubs which have the new BT v6.x firmware.
Warning: BT Business Broadband customers may find their hub is blocked if using this firmware.
This firmware is not suitable for use on long phone lines. The higher than normal default 8dB noise margin employed by this firmware is likely to result in lower connection speeds. If you are on a very long line and barely connect at 512 kbps, you may not even be able to establish a connection using this firmware. However, if your target noise margin set by your ISP is greater than 8dB, then you can consider using this firmware.
Nigel advised there was a new firmware in circulation which can unlock both Single and Dual SSID models. The new SingTel firmware could be found on the Comunidad Underground de México forum where a list of firmware files for 2Wire routers.
He has tested this SingTel firmware on his Dual-SSID 2700HGV model (hardware version 2701-100589-005 reported in 'System Details' page). He reports he now has 6 wireless power level settings, 13 wireless channels and support for WPA2-PSK with this new firmware.

Enhanced services 'Internet Access Controls', 'Content Screening' and 'Firewall Monitor' can be installed simply by entering the regular BT key code: 528Y-27G4-A222-22BJ-B22V.
I have tested the SingTel firmware on my Dual SSID hub. Hardware version 2701-100589-005 (Assembly no. 4201-003003-007). It has also been tested on a single SSID hub by Ted.
If you are fortunate to possess a hub which still has BT v126.96.36.199, you may prefer to just change the ACS URL rather than reflash the hub. Click here for instructions.
(1 Feb 10): Mark W. wrote to say he tried to install the Singtel v188.8.131.52 firmware onto a spare hub (Assy no. 4201-003003-008, BT v184.108.40.206, serial no. beginning 1408) via ethernet using FireFox web browser. Unfortunately the hub became bricked with three solid red lights.
The hub in question was last in use in middle of 2009, which was around the same time BT had started to aggressively deploy the new BT v220.127.116.11.1-enh.tm firmware.
There is no explanation why this particular hub became bricked as I am aware of other -008 hubs which have successfully downgraded to Singtel and BT v5.29.107.x firmwares.
Here are my general installation instructions for installling new firmware:
WARNING: Flashing new firmware to your BT 2700HGV hub, is done so at your own risk. You could damage your hub beyond repair.
home/tech/upgrade.html gateway.2wire.net/tech/upgrade.html 192.168.1.254/tech/upgrade.html or
home/upgrade.html gateway.2wire.net/upgrade.html 192.168.1.254/upgrade.html
The whole upgrade procedure only takes a few minutes to complete. The power LED on the router remains red in colour during the upgrade process. In this time, do NOT be tempted to unplug the power from the hub.
Ensure 'ATM PVC Search' is set to 'Disabled', otherwise the 'ATM Circuit Identifier' and 'ATM Encapsulation' settings have no effect.
The following text is specific to the SingTel firmware only
If you check the wireless settings page, you should see:
My view is enhanced services such as 'Internet Access Controls', 'Content Screening' and 'Firewall Monitor' tend to be ISP specific and require to be downloaded and installed using the ISP specific key code. The default SingTel key code embedded into the SingTel firmware should provide you with 'Firewall Monitor' enhanced service only. For 'Internet Access Control' and 'Content Screening' to be added, you will need to use the BT keycode.
Manual Setup key code: 5225-2374-WG62-22AS-BJ7P
BT key code: 528Y-27G4-A222-22BJ-B22V
I used the BT key code to install Enhanced Services. The default SingTel key code embedded into the firmware only provides the 'Firewall Monitor' service.
No newer firmware should be available or if one is offered, do not upgrade. Click the 'Back' link to quit the page.
Do not worry if you do not see anything listed under 'Enhanced Services'. Try using the 'View available upgrades and options' again later. Alternatively, be patient and you may see the enhanced services automatically appear a few days later.
Otherwise from my past experience with a BT 1200 router, the Enhanced Services are not always installed straight away from the 2wire provisioning servers unlike the BT managed provisioning servers. It may take hours, days or even months (on one occasion) for them to eventually appear automatically, by the unexpected appearance of the 'Parental Controls' button.
Installation Test notes:
Update (9 May 2008): Ted has advised me he has successfully installed the SingTel firmware on his old single-SSID hub. His hub has Assembly No. 4201-003003-006, which is a Hardware version 2700-10588-005 hub
Update (20 May 2008): Spencer installed the SingTel firmware on his old single-SSID hub (Assy no. 4201-003003-006). It seemed to work fine for a week, then he lost connection. BT completed some line tests which seemed to make the router spring back into life or it was a coincidence. The problem re-appeared a few days later but this time it was not fixable. Now using a different router resolved his connectivity problem.
Update (6 May 2008): I have tested the SingTel firmware on my Dual SSID hub. Hardware version 2701-100589-005 (Assembly no. 4201-003003-007).
This SingTel firmware appears to use the standard 2Wire provisioning servers at 2wire.com.
Wireless Power settings of 5 and 6 have no measurable improvement in transmitted wireless power on Dual SSID hubs which are hardware restricted to 100mW regardless of what is reported in the Detailed Logs.
Ted reports when he raises the power setting from 4 to 6 on his Single SSID hub, he does observe a small increase in signal strength from 94 to 97%. This observation may be sufficient to indicate that settings above 4 (to 10) continue to work on the earlier single SSID hub hardware as with same hubs installed with SBC firmware.
I have observed the enhanced services are not deleted if I subsequently change from using the BT key code to the 2wire manual setup key code, beginning 5225- .
A few hours later, I have observed the number of Wireless Power settings offered in the Wireless setup page has mysteriously increased from 6 to 10 possible settings. I am using the BT key code, although I am wondering whether the 10 wireless power settings may have appeared when I temporarily switched to the manual setup key code beginning 5225-. But of course, settings above 4 have no effect on a Dual SSID hub. 10 available settings may be compatible with the older single SSID hubs.
I can confirm Nigel's observations the default minimum noise margin is 8 dB. BT firmwares use 6dB minimum noise margin. The higher default noise margin is likely to result in a lower ADSL line sync speed if the target noise margin set by your ISP is less than 8dB.
If you have a BT wholesale IPstream connection, to determine the downstream target noise margin on your line, reboot your router (Assumed not to be a 2700HGV running SingTel firmware of course!). Then check the ADSL line statistics reported by the router. You need to find the 'Downstream current noise margin'.
You can see below my hub connects at 5,216 kbps and the downstream noise margin is reported as 10dB. I know for a fact my target noise margin is 9.0 dB. This is higher than the 8.0 dB figure used by SingTel firmware, and therefore I would not suffer any degradation in line speed by installing SingTel firmware.
nb. It should report 9.0 dB (Downstream) because BT openreach have set a 9.0 dB target noise margin on my line. I did not reboot my hub prior to taking this snap shot hence why it is incorrectly reporting 10.0 dB
