| Type | Medium | Tech | Max theoretical speeds? |
| ADSL Broadband | Phone Line | g-dmt ADSL2+ | 24Mbps (ADSL2+) |
| Cable broadband | Coaxal Cable | DOCSIS | 200Mbps (EuroDOCSIS 3.0 4 Channels) |
| Mobile Broadband (Pay-as-you-go also good for providing a failover back-up) | 3G Cellular | HSDPA | 14.4Mbps (HSPDA+ 42Mbps) |
If you need to configure a Router manually (or check the settings) the values you require are:
VPI = 0
VCI = 38
Mode = Multimode (or g.dmt)
QoS = UBR
PPPoA with VC MUX (or VC Based / RFC 2364)
CHAP authentication
Option 4 (off-net) usernames appear in the format of username@homegateway - examples:
username@dsl.ukonline.co.uk or
username@dsl3.ukonline.co.uk or
username@dsl6.ukonline.co.uk
Testing usernames as follows:
off-net diagram here (to help explain the authentication sequence)
1) Testing RAS
bt_test@startup_domain (with this you can only access www.bt.net/digitaldemo site)
2) Testing HomeGateway
bt_test_user@ (then the ISP Home Gateway - to test what Gateway you are connected to) examples are:
bt_test_user@skydsl
bt_test_user@dsl.ukonline.co.uk
bt_test_user@dsl6.ukonline.co.uk
bt_test_user@dsl3.easynet.co.uk
bt_test_user@the_losing_isp_when_migrating
If you connect to a diffent gateway than expected this is known as an SSB (Service Selection Barring) fault
3) Testing ISP authentication
- Auth link
- Radauth/log -p
- can we connect with Test Team off-net connection (requires router with which we can type user/pass)

When checking the line quality - check for
Attenuation (dB) up/down = 8.5 / 17.0
Noise Margin (dB) up/down = 31.0 / 31.0
CRC/FEC errors
Line Length
Line Attenuation should be as low as possible and
SNR (signal-to-noise ratio) should be as high as possible.
The noise margin will fall as faster speeds are placed on the line.
Understanding Line Loss and Measurements
8Mb or 22Mb customers on Mac OS X 10.4 are recommend to download Broadband Tuner 1.0 to improve performance. [Credit: NikiO]
The
directions on finding attenuation/noise margin on the Actiontec router
appear to be missing, so I have included the information here.

new Qwest firmware supports ADSL2+?
The white Actiontec router R1524SU-1 requires the Actiontec Wireless Router Upgrade Card HWC01170-01 to use 802.11b wireless - which to my knowlegde - is no longer made and is a discontinued product.

BT Voyager Booster information
The Voyager 105 may not work with 10.4 'Tiger', but will work fine for Apple Mac OS 9.x, 10.1, 10.2 and 10.3 systems OK.
The Voyager is not currently compatible with Windows XP 64-bit.

(Registry changes at your own risk - install drivers again after running this
tool)
You may see the error message can't get registry value, key is equal to software/globespanvirata/adsl and value is equal to driver type which I have found to be caused by anti-virus software (attempting to protect user form malicious file changes) thus preventing the removal or the install/reinstallation of the Voyager. Best to disable the anti-virus, run the Dr105 utility and then re-install software.
