At the moment, I have the current setup- (AEBS) (Attached to the cable modem) --- - (AEBS #1) MC340LL/A A1354 802.11a/b/g/Final N (Notes:) (Version 7.5.2) "AirPort utility found an Airport Extreme (Simulateous Dual Band II)" <Connected VIA Ethernet> I have the older AEBS- 1 (AEBS #2) MB763LL/A A1301 802.11a/b/g/Draft N (Notes:) (Version 7.5.2) "Airport Utility found an Airport Extreme (Simultaneous Dual-Band)" *Both AEBS I turned both on with 802.11n only (5GHz) - 802.11b/g/n* (It sounded good, but I could be wrong with that choice) *I honestly cannot figure what is causing the issues since it doesnt really give me much info to figure it... I restored everything to default and, I cant figure it.* Is there an issue somehow connecting those 2 AEBS with being different models, since I noticed one of them says "Dual-Band II" and the other only says "Dual-Band". *Both AEBS have green lights on, and they still work... but the faults still show in utility..* (Airport Expresses) - (2) MB321LL/A A126x 802.11a/b/g/Draft N (They are the exact same models) - I am using those both extending the network VIA wireless without the option using ethernet with those 2 too far. Notes: (AE #1 & #2) (Version 7.5.2) "Airport Utility Found an Airport Extreme w/ 802.11n" *Both have green lights on, but it still has the faults in utility* I am basically attempting to making the network as fast as possible and of course as far I can connect to the wireless. I have messed around with all the settings for a while. Thanks in advance if anyone could point me somewhere setting up this whole setup since I can't seem to get it working properly.
