    Thanks Lost Account,

     

    i mean i dont know man, i have an iPhone 5 and when im in my living room, about 20 ft away the airport extreme, the wifi level drops from 3 bars to 2 and then goes back to 3 bars after like a few seconds, and if im in the kitchen about 28 ft away from the airport extreme its a constant 2 bars, i mean i dont get it..

     

    i though the airport extreme was supposed to have better range than the airport express 2nd gen, thats the reason i even boguht the airport extreme because at first i bought an airport express.

     

    i mean, with my Dlink Router i had 3 bars in my iphone throught the apartment, one thing with my Dlink router though, was that it ran on the G band, not N, could it be that G gives better range?

    N does have more range. One thing you might want to try is turn off wifi for the router you don't want to use to minimize wireless interference.

     

    See http://support.apple.com/kb/HT1365 for more.

     

    I wish I could give you more info re your iphone. Temporarily have your iphone forget all wifi networks but the extreme's so that it can't switch wifi networks behind the scenes. This might explain why it goes from 2 to 3 bars suddenely, it might be changing wifi networks for you because one has better recepetion.

     

    See this table for more info regarding range. Indoor range for G is approx 38 meters and N is 70 meters, outdoor range is higher because there are fewer objects for the signal to reflect or bounce from — the path the signal travels on is not as obstructed. see, http://en.wikipedia.org/wiki/IEEE_802.11

     

     

    Turn off all other WIFI radios that you can to provide your extreme a 'clean' environment to work in. The shape of your home might be a factor which can impact network performance as experienced on your iphone.

     

    I would do the following, visit speedtest.net or download the speedtest iphone app. Before the steps, consider turning off all network activity, for example other downloads/streaming going on and turn off wifi, if possible, on other routers to reduce interfernce, see HT1365 article for more on that.

    1) run the speed test near the router (same room as extreme)

    2) walk away from the extreme, where you see less wifi bars and test again

    3) compare results of test.

     

    Hope this helps.

    Ahh, how could I forget…

     

    Consider this:

     

    Alt click your WIFI icon

     

    You will see your network display but with extra info (you need to do this on a mac). To see info about other networks simply hover over those networks and a yellow note displays.

     

    Take note of the channel and PHY Modes neighbouring networks use. If any network is using a channel that you are using then really consider altering the channel your Extreme is using, especially if the PHY Mode is the same.

     

    If you are not sure what to do, take note of the Channels and PHY Modes and reply to me with those and I can better advise you what to do.

    Okay , so i ran speedtest on my iphone in the same room that the airport extreme is in and it brought results of download speed: 22MB and Upload 1MB which is great,

     

    Now i walked away about 25 ft from the airport extreme to the living room, as anticipated , the wifi bars dropped to 2 bars, i re ran the speedtest and the results brought 19MB download and 0.8 Uploaded, quiete shocking..

     

    im not sure what to make out of this.. i mean seems like its very fast even when its on 2 bars?

  • Lamonsas Level 1 (0 points)

    One more Question, which Security Mode should i use? i currently have it set to WPA2, thats was the airport extreme set it to by Default,

     

    is WPA2 slowing down my connection more than WPA?

     

    Also, does it matter how many DIGITS is my WPA2 password? if i have more digits does it affect the speed of wireless devices?

  • Lamonsas Level 1 (0 points)

    Please help

    Does the LENGTH of the password matter on the network perfrormance, i have a 12 digit password, would the wifi be faster if i used a 8 digit pass instead?

    The iPhone 5 has the best wifi antenna gain for the 5 GHz band on channel 36.

     

    http://www.anandtech.com/show/6330/the-iphone-5-review/20

     

    Also it supports 40 MHz channel width.

     

    Best settings are:N only, 40 MHz, channel 36.

     

     

    Coincidentally channel 36 is the only channel the Apple TV 3 will ever use the second wifi antenna.

     

    http://www.anandtech.com/show/5687/apple-tv-3-2012-mini-review/3

     

     

    so it's the best config too. (only 20 MHz tho)

  • dbundi Level 1 (0 points)

    So would it make since that if I have ATV I should lock 5ghz channel to 36?

  • tsb3 Level 1 (0 points)

    Yes, best settings for iPhone 5 and Apple TV 3gen on 5 GHz Wi-Fi are:

     

    mode: N only

    channel: 36

    bandwidth: 40 MHz

    Deleted message....posted to wrong thread.

    Ok now I'm really confused...my AEBS only gives me the options of 802.11a/n - 802.11b/g/n (automatic), 802.11a/n - 802.11b/g, or 802.11a - 802.11b/g ?

    Also ,I don't see an option for bandwidth under "wireless options"?

    I'm concerned that my ATV is behind two walls and will not pick up the 5ghz signal.  I have never had any issues, up until recently, downloading HD movies.  I am trying to trouble shoot my end before I start the process of blaming my ISP!

     

    Thanks

    36, 40, 44, 48 if you are using mac book pro's.... upper channels aren't supported

    36, 40, 44, 48 if you are using mac book pro's.... upper channels aren't supported

     

    Wondering why my Mac Book Pro has operated just fine for the last 4 years using Channels 149, 153, 157 and 161.

     

    From System Report:

     

    Supported Channels:          1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 149, 153, 157, 161, 165
