About info is one of the UK's largest DSL broadband resource & information sites.

This site contains a wealth of information such as how ADSL & VDSL (fibre) broadband works.
There's tips on choosing an ISP, help comparing ISP prices and ISP performance.

A large section of the site is devoted to self help diagnostics and what to do if you run into problems with your broadband connection, such as how to get dsl line stats from your router to understanding how such things as SNR and attenuation can affect your connection. There's also a vast array of tutorials and FAQs about broadband.

It is independently run and a not for profit site.  Unlike some broadband sites, we do not focus only on ISPs which pay commission. Although the site is well known and respected within the ISP industry, our position means that we are free to tell you 'as it is' and allows us to carry information on far more ISPs than most other broadband comparison sites.

If you have a broadband problem and need some help - or just want to say hello - our community forum is frequented by many knowledgeable people, who may be able to assist you. We are a family friendly oriented site so please feel free to join us.

The site is continually expanding, with new pages being added or amended. New pages are normally announced on the Forum.

xx Openreach MCT modem list - updated.

July 25, 2017, 08:08:06 PM by kitz
I've updated the list of modems on the Openreach Modem Conformance Testing page.
New additions to the list are a few Cisco and Kenton Comtrend modem/routers.

Modem Conformance Testing (MCT) is a series of tests carried out by BT to ensure that modem/routers are compatible with BT Openreach's FTTC cabinets and conform to VDSL2 mandatory requirements for transceivers as specified in ITU G.993.2.

xx Forum registration and use of VPNs

April 08, 2017, 06:12:40 PM by kitz
We have recently had a few attempts for new users to register for the forums whilst using a VPN service.  In light of the UK ISP Internet Snooping act we fully understand why so many people may wish to use VPN services.

However the downside to using one of the many free/cheaper services is that it is possible to be allocated an IP that has in the past been used by spammers.  We have several anti-spam measures in place, one of which is if your VPN IP is on the spam database, then application to register will automatically be rejected without further notification.

Whilst we respect your wish for anonymity, please also respect that we are a family friendly community and have zero tolerance towards bots and spammers.  This makes a better and much nicer environment for our existing members.

If you are using a VPN and are having difficulty registering, it is highly likely that your allocated IP is one of those previously used by known spammers.  We suggest that you temporary turn off your VPN just whilst completing the registration form.

xx Faster sync speeds on the way? Openreach to rollout 3dB target SNRm for FTTC

November 14, 2016, 09:14:52 PM by kitz
Good news for those with stable Openreach FTTC lines which could see small increases in their sync speeds next year.
The current default target SNRM is 6dB but with effect from March 2017, the NGA DLM (Dynamic Line Management) may select 3, 4, 5 or 6dB depending upon how stable the line is.

We had been monitoring the Openreach trial of a 3dB Target SNRM on our forum which was undertaken in April earlier this year.  Those users who were on the trial saw their speeds increase and on the whole the trial appeared to be sucessful.

Based on our observations speed increases are roughly in line with the following figures.

~ For existing Sync speeds of around 20Mbps -  each 3dB is worth 3Mbps
~ For existing Sync speeds of around 40Mbps -  each 3dB is worth 6Mbps
~ For existing Sync speeds of 60Mbps or more - each 3dB is worth 11Mbps.

BT wholesale ADSL (copper) lines already have a 3dB profile available to them.  Obviously this increase wont make any difference if you are already syncing at the maximum speed ie 80Mbps or 40Mbps if you are on a 40/10 or 40/2 product.
