    And don't forget your neighbours who may be using Wi-Fi, video senders, DECT 'phones, Bluetooth, microwaves, etc. I can 'see' the wi-fi network of one of my neighbours whose house is fifty yards away.

    Just pray that one of them doesn't decide to use a 108Mbps network, since they bond together several channels in the middle of the the 2.4GHz band, so effectively interferring with the quality of channels on either side of them.

    Dect phones have their own space at 1.9Ghz so theoretically won't interfere with wifi - however newer US equipment that has been set up incorrectly (and illegally) to use this band may well interfere with or be disrupted by DECT. This is because 1.9Ghz has recently beein opened up as unlicenced frequencies there similar to 2.4Ghz.

    Up until recently, my laptop would occaionally log into a neighbour's WiFi instead of mine - for some reason they had a completely open connection with no password protection!

    How did they manage to get that signed off by the ITU or the world's various telecoms regulators? :eek:

    Does 811n technology still stick to a single channel though but with Multiple Aerial In Outs (MIMO)?

    You can usually set your own laptops wireless card to tell it to only connect to networks you have Profiles for and not just to any open access point though.

    The problem with logging on to the connections of technically illiterate neighbours, accidentally or otherwise, in a not very densely populated area is that their equipment still often gives them a message telling them it is happening and the name of the connecting computer or network. So in the long run it can still be a recipe for very angry neighbours, some of whom may see it as being like you having the cheek to walk into their house uninvited just because they left the front door wide open................................

    Better to play safe and set your wireless card to only connect to networks with approved profiles when you are at home.

    Yes, it's now removed from the list of possible devices after a frustrating couple of minutes wondering why the logmein connection from the laptop to the office PC was running so slow. It was going over WiFi to the neighbour's router, through the internet to my broadband connection rather than peer to peer... That would slow it a bit, especially with a very weak wifi connection!

    My brother spent ages once with his downstairs PC and a Belkin USB wireless adapter, to see files of his upstairs PC connected to his Belkin ADSL wireless router. Internet browsing/email from downstairs was fine, just couldn't see other PC.

    When I finally got a look at his setup downstairs noticed two issues, one the router start page when accessed downstairs didn't look quite the same as when accessed from upstairs and despite setting SSID only network we could see was Belkin54G.

    Then it dawned on me the upstairs router was Belkin ADSL and router downstairs was a neighbours Belkin ethernet router conntected to NTL. He had been using it for months and just e-mailed files between upstairs and downstairs PC as they could not see each other directly.

    Changing wireless channel from default and suddenly could see SSID of his ADSL wireless router, connect and share files (and add WEP onto wireless).

    Never did find out whose the open router was.

    Its amazing how many people just pull the routers out of the box and start using them with default settings - and with this in mind its even more amazing that the manufacturers of some routers leave the default settings wide open. I suspect I could access the admin screens of more than half the Belkin routers I come across as nobody ever bothers changing the default IP number and password!

    It also depends on the area you're in apparently. Where I used to live in Kent, people seemed to be quite closed and everyone had secure encrypted connections. In Swindon, a friend informs me that the majority of routers are left open for free internet access. Where I now live, I haven't really had much chance to drive around with a WiFi enabled device to see what pattern emerges here, but it looks like a mixture of open and "already locked when out of box" solutions.

    Anyway, I'll stop now as this is definitely off topic by now :eek:

    There's a lot worse to come. They're currently proposing to massively increase the maximum signal level of the 2.4GHz and 5.3GHz bands to enable a single Wi-Fi network to cover complete neighbourhoods. That's going to make it increasingly difficult to find your own Wi-Fi channel, and virtually impossible to get a clean signal with a video sender. I responded to OFCOM's consultation document with a suggestion that they only do this with the 5.3GHz band, but I doubt that they see the use of the 2.4GHz band by video senders as a serious consideration.

    I'm surprised that networking products haven't appeared that will send video using buffered transmission. My Xbox 360 MCE extender is effectively doing that already, but is over-engineered (and overpriced) for the job.

    Really? yours must have some sort of serious problems as I can download using both TYTools and Filezilla at 990 KBYTES which is damn near 10 mBITS. Unless you meant to write 2 MBYTES of course...

    I routinely get over 3Mb/s.
