    Hi,

    Forgive me if I raise this issue, as no doubt I'm sure it has been the point of countless discussions, concerning wifi safety.

    I've been using a traditional ADSL 10/100 connection, but find that I now need to expand Internet use to two other computers. Life would be obviously so much easier if I could go wireless to facilitate this.

    Can anyone recommend where I can research the latest findings regards wifi safety?

    Many thanks. Much appreciated.

    Rgds

    If this is for your home then is not the standard encryption of the IP addresses etc not ok for you?

    Hi,

    Thx for your response. Forgive me as I know little about this. Yes, it is for home - Are you referring to ICS or proxy?

    You will have an SSID which will identify all of the PCs on the wireless network you can set this not to be broadcast this will be an option with the software you get whilst setting up the wireless network. (SSID must be the same on all PCs this is normally set by you)

    You can then encrypt using WPA2 which should be an option with the network software, it was with mine, then obviousley you should have your standard firewall.

    Thats as far as I know about wireless networking because thats how mine was set up but because I live in an area where there is bad signals I reverted back to a proper ADSL connection.

    However, the SSID can still be "sniffed" out of the air, even with encryption turned on... the SSID is sent in clear text.

    Using WPA2 should provide better security should it not? better than WEP anyhow.

    Hi Rosie1

    If you are talking about WiFi safety regarding radiation then perhaps the following will help.

    I work in a private school and this very subject was quite a live wire a few months ago. The above was quoted from a Physics teacher after a certain Panorama prog.

    Basically, you are more "at risk" from your mobile phone than wireless radiation.

    Having seen AJ's response - I have to ask "What do you mean by safety?".

    Radiation hazard? In which case AJ debunks things nicely.

    Break-in/encryption hazard? Then ditch WiFi and wire it.

    now now harry, anyone that paranoid would need to surround their home in copper wire otherwise I could just sniff the EM emissions from your monitor!

    What about the tin-foil? <giggle>

    Seriously - these days most in-town locations are overlapping badly. The throughput will decline, and opportunities for break-in will increase.

    If you don't like cables(or the better-half is complaining) then look at Homeplug.

    Hi everyone,

    thank you all so much for your responses.

    Regards what aspect of safety - health risks and encryption. Technology moves along quickly and it's trying to keep up. Everybody has their own opinions and it's weighing up the balance.

    In terms of 'war driving', if that's the correct term, I live in the countryside in a village location (not that it would completely rule out violation) so perhaps the risk may be minimal.

    In terms of health safety, I've heard that some people suffer (member of my family complained of headaches when they had their wifi in use). Like anything new, I guess it may be that it hasn't been around long enough to get a true picture. However, where children are concerned, is it worth the risk?

    Thank you again. I'll utilise your guidance. Very kind.

    Rgds

    just use common sense :)

    that it WPA2 +Hide SSID +Mac filtering.

    I know that all that can b broken but honestly - if someone want's ur internet that badly - let him :)

    oh and btw - WiFi will NEVER be secure

    I also live in the country side and because of poor Wi-Fi signals, must be the hills n stuff I went back to proper ADSL wired connection.

    do you already have the hardware or would a recommendation be your next question ?

    if you already have the hardware let us know and we can advise the best way to secure it.

    As said wireless will never be 100% secure there will always be a way to crack it. Your best bet would be WPA2 and MAC filtering, although i'm not to sure hiding the SSID will do much because it can easily be sniffed and it may cause you problems trying to connect to the access point. WEP is the most basic form of encryption which will keep people from wardriving your connection but only takes minutes to crack where as WPA and WPA2 takes much longer.

    Hi,

    Thx all ever so much. No, haven't bought hardware yet; thought it best to page the oracle.

    Haven't heard of Homeplug until now. Did a wee bit of sniffing on the Net, and spoke to a supplier, but may be biased, of course. I'm intrigued. Can anyone enlighten me as to how it compares to wifi in terms of efficiency and the other sub topics that we've covered. Does anybody on the forum utilise this?

    Rgds to all, really appreciated.

    obligatory wikipedia answer - homeplug :tune

    these are the sorts of speeds you'll be looking at.

    14Meg Homeplug adapter: 7.5Mb/s
    85Meg Homeplug Turbo adapter: 25Mb/s
    200Meg Homeplug adapter: 40Mb/s
    54g Wifi - 14Mb/s

    I'm a recent convert (this week) to homeplug and it is, imo, the giraffe's genitals. It does everything it says on the tin, including the one minute setup time. Simply plug an ethernet cable into a spare port on your router, plug it into the adaptor (looks just like a normal electrical plug) and plug it onto an electric socket. Plug in the other adaptor anywhere in the house, plug an ethernet cable into that, run it to laptop/PC. Bingo, job done! 8)

    Hi Rosie,
    As regards powerline adapters I work for BT and they have just started using them to connect there Vision Boxes. They are made by a company called Comtrend and need no configuring at all just plug them both in wait 10-30 secs for lights to go green and one to act as master then plug in the ethernet cables = finished:). They can be expensive if you needed a few of them so I would look into wireless and compare prices before taking the plunge

    Hi,

    Thanks so for the info. From snippets I'm picking up, sounds like these plugs may do the trick. I'm trying to work out whether to aim for an 85mb or 200mb. We use webcams, I hope to do web development, and poss we may utilise online film/gaming.

    Any opinions?

    Rgds
