I was browsing this afternoon at 130Mbps completely stable. Its now jumping between 39-78Mbps and keeps dropping out.

infinity 2 is max 80Mb/s
though you could always look at the router (hh3) log and see if/when things connect.

You're talking about the indicated speed of the wireless link on your computer. In many areas, the 2.4GHz band used for the majority of Wi-Fi is heavily used, with multiple wireless networks and other users of this band all interfering with each other. I think having FON enabled is a red herring - it's simply the heavy use of 2.4GHz in the evening.

The best answer, if possible, is to use wired connections where possible and put what Wi-Fi you can on the 5GHz band - though many devices do not support it and the lower range of the higher frequency can be an issue. Usually, 5GHz is supported by dual band devices, which offer both the 2.4GHz and 5GHz bands.


I don't believe the BT Home Hubs are dual band, so you will need to install a dual band capable access point, also ensure that any computers and other devices are 5GHz capable. We have dual band wireless here and I can't see any other 5GHz networks. My Dell Latitude has a dual band wireless card, as do our more expensive tablets and mobile phones. The cheaper tablet, a couple of older mobile phones and an old Windows XP netbook are 2.4GHz only.


Investigate different wireless channels to see if you can optimise the performance - though be aware overlap means there's really only three non-overlapping channels on 2.4GHz - 1, 6 and 11. 1, 5, 9 and 13 have minimal overlap, but the number of devices on 6 makes a four channel 2.4GHz strategy unworkable in many locations.

If all your devices support it, channel 13 can be a good choice.

I second the 5GHz recommendation - note that 5GHz doesn't travel through thick walls, but works in open spaces and goes through windows.

I would also grab inSSIDer (on Windows, and Android) and install on a laptop and find out what is going on:

For Mac I wouldn't use inSSIDer as its got issues, but use WiFi Explorer from the Mac App Store - its a few pence cheaper (yes, inSSIDer is paid on Mac):

Sadly no WiFi scanning tools for iPhone/iPad yet.

There are free ones for the Mac as well. I've never tried them, but see for example http://www.makeuseof.com/tag/awesome-free-wifi-scann...

I tried that one and it worked well on Snow Leopard, but on Lion and now Mountain Lion it struggled. It might have been updated - but the £1.99 on the App Store for the other one is worth it as the graphical display really nice.

It's easy to disable FON through the HH3 interface. In no way is it contractually compulsory as an earlier poster has indicated. One of my neighbours actually came round to ask if I minded him using my FON! A propos of nothing, does anyone know why I'm broadcasting BTWifi and BT Wifi with FON as two separate networks?

Yep I noticed

FON being separate to BTWifi(formerly openzone) I believe but giving similar access.
