Hi,

When I set m y router to 2.4GHz I have to wait forever to buffer movies that I have on home sharing on my ATV, I can switch my router to 5GHz and movies don't need any loading time - they play straight away. Now the problem I have with this is that having my router set to 5GHz means that I lose wifi connection on my iphone.

 

Does anybody have any suggestions as to why the 2.4GHz setting is so slow? Can I get around this issue?
Thanks very much


MacBook Pro, Mac OS X (10.7.3)

    If you are only encountering problems when transmitting at 2.4 GHz, then I'm inclined to think that your network is experiencing interference. Try changing the channel your network works over.

    As Winston Churchill says it must be interference since the 2.4 GHz is faster than most internet connections anyway.

    Try holding the option key when clicking the airport icon in the menubar - that will show you the channels of nearby networks. Then select a different channel for your own.

    I am on a 10 Mbit internet connection and can stream HD movies without any problems.... The 2.4 GHz is at 54 Mbit so a lot faster than my internet.

    I have 4 devices on my 5 GHz and 4 on my 2.4 GHz and streaming through Home Sharing on multiple devices is not a problem....

    Thanks for the replies. I guess that all makes sense

     

    However... I just tried manually setting a channel (to one that neighboring routers weren't using) and it didn't make any difference on 2.4GHz. I even turned off the two other devices in the house that were connected to the router.


    Change to 5GHz and it still runs smooth! Strange!

    And it is not a dual band router?

    Can you check the speed on your wifi network when on 2.4 GHz compared to 5 GHz.

    The problem is, it isn't just neighbouring networks, household items such as baby monitors and cordless phones can use the 2.4 GHz band as well, thereby creating interference. Try a few different channels, sometimes removing the Apple TV, even only a short distance, can help.

    It's a virgin media superhub that I'm using

     

    Where I'm currently sat using speedtest

     

    2.4GHz - DL speed 7,92  UP speed 0.84

    5GHz - DL speed 13.95 UP speed 3.12

     

    So there's obviously a big difference here! Thanks again for all your help on this chaps.

    Unless the network is suffering from some sort of interference or other problem, there shouldn't really be any difference between the speeds of 2.4 GHz network and 5 GHz network. (It's the type of network, g or n, that will make any difference to the speed)

     

    If those readings that you have given are in megabytes per second, then you should have no problems on your network. If however they are in megabits per second, you do have a problem.

    Thanks Winston, very helpful.

     

    And yeah, I spent an hour this morning going through all my channels and testing them. I chose the best one on 2.4GHz where I was getting full connection speeds... so I guess the 5GHz won't help in this instance.

     

    Unfortunately this hasn't helped the Apple TV issue. Still taking 5 minutes to buffer a 150mb movie enough to play.

    As Winston Churchill says it must be interference since the 2.4 GHz is faster than most internet connections anyway.

    What?

     

    2.4Ghz should be slower than 5Ghz, as the later band can encode much more data within the same time/space.  The only reason the iPhone is still set to operate on 2.4 is because despite being much slower, the range can extend to double as that of the 5-band. This tends to be more important for those types of portables.  You are not going to find any modern Mac which prefers 2.4 over 5 of course.

    You are talking drivel, 5 Ghz isn't any faster than 2.4 Ghz.

     

    When the poster states that 2.4 GHz is faster than the Internet connection, what in fact they are referring to is that the local network in the vast majority of cases is faster than the wider area Internet connection.

    5 Ghz isn't any faster than 2.4 Ghz.

     

    Let me rephrase this a bit better since I"m always posting in the middle of the night.

     

    The 5 Ghz is using a much less crowded area in its space/spectrum, whatever you wish to argue/name it. This GENERALLY means you are going to have much less interference, and higher speed transfer.

     

    On the flip-side, due to the higher frequency, you start to take a drastic hit on range because it is too easy now to deflect through common day things such as walls, etc.
