Can two wireless routers (802.11g and 802.11n) coexist in the same home?

    I have an old 802.11g Airport Extreme and a new 802.11n Airport Extreme.

    Can I set up both of these wireless routers in my home so that my iMac G5 and iPhone (and maybe some friend's computers when they come over) work with the old 802.11g router, while my MacBook and AppleTV take full advantage of the 802.11n speeds of the new Airport Extreme?

    If so, how would I accomplish that? Will I still be able to transfer files wirelessly between all of the computers?

    I already tried searching for answers, but was not able to find any related posts.

    Hardwiring the iMac G5 is not an option (and why is the iPhone not 802.11n).

    Thanks in advance.

    Well.....I dont understand the point to all this....your 802.11n Airport can be hardwired with up to 3 computers and then whoever is wireless can get access too...

    the 802.11n airport is still compatible with b/g wireless modems.......its just they wont be able to get "n" I dont even think its possible unless you have 2 different modems to hook up two seperate routers....

    Does your iMac G5 have an airport card?

    Thanks for the reply.

    Yes, I have wireless g with the iMac G5. I can only use wireless with the iMac G5 because it is not near an ethernet port in the wall.

    I currently have the Airport Extreme 802.11n as the only wireless router connected to my modem (which is in my closet) and all computers and peripherals are running off that (mixed n and g).

    What I want to do is take full advantage of 802.11n speed without allowing 802.11g devices to cripple the speed of that router.

    Is a solution possible?

    You could try but i'm not sure would it work...

    You'll have to input the MAC address of the system(s) you want running on 802.11n into the appropriate router and set it so it'll only accept connections from those addresses, this will block all other system from connecting to the said router - this will prevent the "n" network becoming a "g" network. Also on those systems you must tell them to only connect to 802.11n router.

    On the AirTunes (would imagine it'll be the same for APEBS too)
    the MAC Address Access Control is located in
    Airport UtilityAccess Control
    Change the setting from Not Enabled to Local,
    then proceed to enter all the MAC Addresses you like...

    On the other router (802.11g) set the network name different, and also input the MAC address you like (though optional)

    Inserting the MAC address on certain routers will force each system to connect to the correct router, thus avoiding slow downs in your network - I haven't tested it, but logic tells me this will work.

    Make sense?

    Yes this works

    Use the AEBSn as the router and plug the AEBSg into it. You'll need to change a setting or two on the g routher. The two networks will have two different names but when you're connected you should see computers on both networks.

    Yes, as suggested you need the following layout

    Modem -> AEBSn -> AEBSg

    Activate wireless on both base stations but make sure that each wireless network has different SSID's

    Enable DCHP on the AEBSn and disable it on the AEBSg

    With Linksys routers you can enable a "Mixed" wireless signal that consists of A/B/G. I figure the AExtreme can do this too with the inclusion of N. Then whatever computer wants whatever Signal can use it. I am speculating.

    But to do what the OP wants to do, you want to DISABLE this "Mixed" feature... I don't own and AE, so I don't know how to do so.... Theoretically, if you did this, your "G" Macs would not be able to connect to the "N" network. You would then get the added "benefit" that when your friends come over, they would connect to "N" or "G" depending on what their laptop supports...

    I have my old DLink DGL-4300 set up to handle G devices and my AEBS set up for N. I prefer the more robust SPI firewall and dynamic DNS support on the DLink so it handles the internet connection.

    Cable modem -> DLink -> AEBS

    Set each wifi up with a different channel, and a different SSID.

    Set up the AEBS to be in bridge mode. It will pull its IP address from the DLink, as will the other computers connecting to the AEBS wireless network.

    Works like a champ for me. All devices on the networks can see each other, have the same IP address range, can use the Airport disk, and print to the network printer.
