WiFi radiation? Is it dangerous for health?

I've heard different things about this subject. I'm not sure what I should believe. Are wireless routers and airports dangerous (dangerous might be a little bit exagerated) for humans?

There is no definite answer. There has been and continues to be debate about whether EM radiation is dangerous and if so in what strengths and frequencies and at what exposure times risk increases significantly. There are many reports, studies and downright guesswork that you can read if you wish to research the subject. Given, though, that studies have shown no verifiable link between brain cancer and cellphone usage, and cellphone EM radiation is almost certainly stronger (given the proximity to the head of normal cellphone use) than WiFi, your risk is probably low.
Regards.

  • 2 New Ipads (Retina and Mini)(New to Apple) How do I share purchased apps, but others have each act independently? Mini is for the Wife the Ipad4? is for me. I want to use mine at work, etc. She's home with the kids. Can we set them up seperate, but share

    2 New Ipads (Retina and Mini)(New to Apple) How do I share purchased apps, but others have each act independently? Mini is for the Wife the Ipad4? is for me. I want to use mine at work, etc. She's home with the kids. Can we set them up seperate, but share
    --break--
    So we are entirely new to Apple products. I'm an IT guy, but have always been a windows user.
    So the Ipad with Retina Display is to be mine (and will use it at work for notes, organization, etc)
    The MINI is for the wife.
    But, are we allowed and can we.. buy an app and share that app between both devices? IE. Can I buy a copy of Angry Birds for the House and both Ipad's use that single purchase? and if so, can we still run the Ipads seperate other than to share the apps purchased. IE my facebook and email set up on mine and hers on her ipad mini?
    When I finally find a note taking app I like, can I share it on her ipad, without her having all my work files, etc?
    Thanks for helping out the apple noob. Hoping for a great experience, and anticipate droping $100 in apps the first day.. just don't want to do that twice. If this is against the usage policy, thats unfortunate but good to know. (I mean we can share stuff on PC as long as its in the same household)
    thanks again (explanations or links are fine)

    There are a number of Apple services: iMessage, FaceTime, iCloud, Game center, Find My iPad, etc.
    Now, to share apps, music and books you need to have the same Apple ID:
    iPad's Settings > iTunes & App Stores > Apple ID > Your purchasing Apple ID.
    For the other service, your wife should have her own Apple ID.
    All she needs is a valid e-mail address, apply Apple ID below:

  • HT1695 My wife is working in London for 5 weeks and for some reason her ipad will not connect to btfon or btopenzones at her digs, but she has a ethernet socket, so can a wifi only ipad2 be connected to the internet via an ethernet cable

    My wife is working in London for 5 weeks & staying in digs, so we thought it would be a good idea to buy an ipad2 so we could skype each other, she could watch movies from the icloud, access skygo etc,and it wouldn't be as bulky as a laptop. All fine if you can get wifi, but for some reason her ipad cannot locate any btfon or btopenzone hotspots (or provider), IN LONDON??!! We can access them at home in a little village in Northern Ireland. Her digs have an ethernet socket, is it possible to connect her ipad to this socket via an adapter?

    No. She will need to come up with an alternative way to connect. A mobile hotspot perhaps.
    Finding some way to connect to these hotspots would be the ideal situation. I know that you realize that. We know nothing about what is happening, but if you can explain in some detail, maybe somebody here can help.

    I suspect that the problem is in your router. Do NOT consider your router to be blameless if some other devices seem to work with it.
    Try restarting your WiFi router by removing power for 30 seconds. Don't just turn it Off. On many routers that doesn't really do anything but put the router into standby mode. If that does not help check for a firmware update for your router. If none exists which corrects the problem consider replacing the router.
    There is a chance that some services turned on in your router could be causing problems. Look for a setting called QoS (Quality of Service). If ON turn it OFF.
    If you need more help please give the make, model, and version of your WiFi router and how you have it configured.

    You are not addressing Apple here. If you have a problem, describe it and someone might be able to help. Just to be sure, the wi-fi on the phone will go off after the phone goes into sleep mode unless it is actively being used. This is a battery saving measure. If you are actively using the internet, and the phone is still awake, then the wi-fi should remain connected.
    What troubleshooting steps have you tried.

  • I have an Imac running OS 10.6.8 All of the sudden it is refusing the password to link with my ATT Wifi network. It asks for a password that is then invalid. I never had to use a password in the past.. can password be reset?

    For what ever reason, my Imac is asking me for my password to join my wifi home network and refuses said password. Is there a way to reset the airport password, uninstall or whatever needs to be done. The wifi is from ATT 2wire.

  • TS1398 My ipad says it is connected to WiFi, which is workingly perfectly for several other devices, will not connect to internet.  It keeps giving the message 'Cannot Connect' or error has occurred or just blink off site or icon?

    My ipad says it is connected to WiFi, which is workingly perfectly for several other devices, will not connect to internet.  It keeps giving the message 'Cannot Connect' or error has occurred or just blink off site or icon?

    Some things to try first:
    1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    4. Go into your router security settings and change from WEP to WPA with AES.
    5.  Renew IP Address: (especially if you are droping internet connection)
        •    Launch Settings app
        •    Tap on Wi-Fi
        •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
        •    In the window that opens, tap on the Renew Lease button

    the Wifi storage options are interesting but it seems they only allow to read files from the device on the iPad but not transfer files to the storage device via WiFi.
    I'm looking for a possibility to use the iPad for photography while traveling, without the access to a computer.
    Shooting photo's in RAW format crates pretty big files that will fill up the iPad's memory pretty fast if you shoot a lot during a (let's say) month long trip.
    my idea was to use load the photo's to the iPad so i could view them and sort out any bad ones. then copy them over to the storage device so i can continue using my CF cards for shooting. I have an image thank for copying the photo's directly to the HDD but it would be so sweet to be able to check them on the iPad before hand.
    any suggestions?

    Check out pogo plug device, it allows you to upload camera roll via wifi.

  • Is it dangerous for my iPod screen that the glass is crack

    Like the title, I'm wondering if the fact that the glass is crack on my iPod touch is dangerous for the screen.

    If the crack did not go through the full depth of the glass, there is no danger at all, except for the appearance.  If the crack is all the way through, it is possible that some moisture or dirt can penetrate and cause some degredation of the screen.  However, if it's appearance is not a bother to you, I think that you should keep using it as it is.  If you have Applecare, then by all means,you should take advantage of it , and have the ipod replaced with an alike model.  Otherwise, you would have to pay to have it taken care of.
