    Issue with wifi caused by BT HomeHub update to software version (Type A) 

    I’ve been having major issues with wifi the past few days, and it turns out they’re all caused by an update to my router by BT. Now, this post is going to seem pretty nerdy, but this issue may affect more of you than you think!

    I’ve spent the past three hours looking into this. You see, I’ve got a pretty complicated home network, fortunately I’m skilled in such things so it’s never been a problem. But it does mean when my wifi became unstable I had a lot of variables to consider and check.

    A few days ago I noticed my internet connections started to drop-out every 40 seconds or so. Whether it was a local connection (one computer at home talking to another) or going out through the internet (searching Google, checking Facebook, downloading files, etc.).

    I didn’t realise it was a wifi problem until I did some testing, after all every one of my devices connect wirelessly, so it seemed to be a problem affecting everything.

    I ran some tests (pinging various machines and remote servers) and it confirmed what I’d noticed. After updating and checking everything I could that I’d set up myself (and extra repeater router, my server, desktop and laptop software) in desperation I checked to see if I could upgrade my BT HomeHub3’s firmware.

    Oh. BT updated it automatically a few days ago. Precisely when the trouble began. A quick search shows a number of their customers complaining that their wifi has stopped working since the update, FYI it’s called (Type A).

    The update “fixes” something called Smart Wifi. The solution is to turn it off.

    There is no setting for Smart Wifi on a HomeHub3. In fact it’s a background process, to turn it off you need to manually select a channel for your wifi to use, instead of the default “Automatic” setting.

    Now, I already was using a manual channel: channel 6. Nonetheless I I thought perhaps I need to change a few things to fix the Smart Wifi issue, so I turned it back to automatic, then once again to channel 6. Still the issue.

    A post on BT’s customer forums alluded that perhaps BT uses channel 6 as a default, so it might not turn off Smart Wifi if I stay on that channel. I can’t confirm if that’s true, but I do know when I changed to a different channel (in my case, 11) SUCCESS!

    All my tests show an excellent, stable connection once more.

    I should trust myself and my skills more–and assumed BT were likely responsible from the outset. They usually are.

      Thank you – there I was wondering what had happened and now, after reading your very helpful article, I realise where the problem lies. I’m not as ‘techie’ as you, so it’ll be a headache fixing it – but at least I know what to do now.

    How do you annoy a web developer? 

    This is the briefest of posts, because the content is entirely thanks to the wonderful xkcd comic, and it’s pretty damn nerdy.

    First person in the comments to exclaim that they get it, and can give some sort of rationale, gets a prize.

      The SPAN element has very similar properties to the DIV element, in that it changes the style of the text it encloses. But without any style attributes, the SPAN element won’t change the enclosed items at all.

      The primary difference between the SPAN and DIV elements is that SPAN doesn’t do any formatting of it’s own. The DIV element includes a paragraph break. The SPAN element simply tells the browser to apply the style rules to whatever is within the SPAN.

      To open a DIV tag without closing it but instead to close a SPAN tag that was never opened creates an interesting conundrum for the browser, resulting in unpredictable and possibly inconsistent layout behavior. It vis the coding equivalent of “The following statement is true. The preceding statement is false.”

        Gabriel, that is a much more complete answer than I was expecting!
