HomeHub 2.0 Faults & Finding the Manufacture Date of Your Home Hub



Going off the many posts on the BT Broadband Community Forum, a fair number of HomeHub 2.0 users are having problems with them. Perhaps the most commonly reported problems are associated with the wifi. Either the range of the router, despite it being type n, is pitiful and worse than earlier type g models, or the wifi keeps cutting out for no apparent reason. Other issues include an inability to hold sync particularly well, and the 8.1.H.G (Type A) firmware upgrade of May 2009 that has caused all sorts of problems, many of which are still unresolved.

Often, the problems disappear when the user goes back to using an earlier version of the HomeHub (1.0 or 1.5) or uses an entirely different router - which does sort of point to the HomeHub 2.0 being the culprit.

A great guy known as DS on the BT Community Forum, has recently been pulling his faulty HomeHub 2.0 (Type A)s apart and found some interesting thing, including:

- trapped and chafed power supply wiring
- finger-prints all over the internal circuitry
- loose/unattached aerial wires
- dirty connector strips for the wifi adapter sub assembly (Top right in the adjacent picture of one of my HomeHubs

I pulled two other HomeHub 2s apart to see if mine had similar issues. Fortunately, the two I looked at did not show any of the faults reported by DS - aside from a single greasy fingerprint on one of the internal components. The power supply wiring for the hub phone charger were well routed, aerial cables properly attached and the aerial plate securely mounted.

Now the question is this. Are these faulty HomeHubs fairly randomly scattered through the production run, or do some batches of hub suffer from more faults than others?

If you are going to report a fault on the BT Forum, or directly to the BT Help Desk, you might want to tell them when your hub was manufactured. To work this out, look at the base of your Home Hub and you will see a large sticker. The serial number appears on the top right hand side of the sticker and looks something like this:

SN: CP0825*****

The first four numbers refer to the year (08) and week (25 = June) of manufacture.

If you are tempted to full a faulty HomeHub apart, it is fairly straightforward by following the simple yet excellent instructions referred to by Jarviser here . Please note that I wore an earthed wristband to minimize the chance of static damage to the electronics.

Be warned though. If you do pull a hub apart, there is a risk that you could brick your hub and it might never work again!

You might also want to add your HomeHub date of manufacture to the list here, reporting whether it works and if it has problems, the nature of the fault.

STOP PRESS If you have any photographs of the insides of a HomeHub 2.0 (Type B), please send them to Jarviser at: jarviser.one@live.co.uk

He wants to add the details to his excellent website.

Having had some major problems with my own broadband service, I understand how others struggle to get help from BT.

There is a lot of good information out there, but it can be hard to find. So this blog is an attempt to pull some of it together, in one place.

It's a blog that really shouldn't be needed - if only BT and possibly other ISP's in the UK, provided useful customer support.
