    I have cable internet from Time Warner. I pay for 10 Mbps download/ 1 Mbps upload.

    The network is very sensitive to traffic -- early/late in the day I reliable see 15+ Mbps; during prime time I get 6-8 Mbps.

    Download speed does NOT seem to be any different regardless whether I'm connected to 2.4 or 5.0 Ghz band on the new base station.

    I'm typically seated about 30 ft from the base.

    Nice man! But I think we need MacWorld and MacRumors to have this on their frontpages, maybe even Appleinsider!

    I thought I was going mad until I found this thread!

    I have a 1tb Time Capsule (new model with improved antennas) and it is hopeless in the 5Ghz band (same problems described elsewhere in the thread, around 420kbps per second throughput and slower to connect initially), but is fine in the 2.4Ghz band (I get about 2.2MB download speed through my ADSL2+ connection).

    This is a real shame, given that I bought it to occupy the 5Ghz band - in my apartment I can see over 20 wireless networks in the 2.4ghz band and only one in the 5ghz).

    The big pain was spending all weekend troubleshooting with no result!

    Fingers crossed that the chipset can be fixed with a software update.

    I also have problems with my new Airport Extreme.

    Sometimes I even need to restart my Airport card on my MBP because it hangs after getting connected to the 5GHz network which is extremely unstable.

    Really weird and I hope the Apple will release firmware for both AEB and my Airport card.

    Transfer between frequences also instable

    A new version of iStumbler has been released for 10.6 with a/b/g/n support:

    Maybe it helps identifying more about this issue.

    Got my third replacement today. Does not help. Same issues: instable 5 GHz, slow transfer rate etc. Tested with iMac 24" and MacBook Pro 17".

    I am going to ask fourth replacement tomorrow. I will replace my unit until I get a working one.

    My guess is they are all defective and that the only satisfied customers are those who either wouldn't recognise the problem or haven't (yet) noticed it.

    After reading all this I feel very lucky. I'm on TWC with 10Mb down and have a TC and AEBS (extending my network) running in dual mode. I bought them both shortly after the came out. I have no issues whatsoever and run speed tests quite frequently. The reason I have been speed testing as I added an ATT Microcell and was curious to determine its impact on I'm downloads. It has none. Consistently have 9 to 10+ Mb download tests. I will gladly explore setups with anyone to determine any differences. Let me know.

    Thank the Lord!!!! I was going crazy. I had Time Warner people come and replace modem. had to take off work on two occasions. I have a 1tb time capsule and a mac book. Any news on a fix? Who do I have to speak to at apple?

    I have this same problem. I bought this APBS primarily for the 5Ghz support as I live in a condo where everybody and their brother is on 2.4Ghz and I'm the ONLY one using 5Ghz. Looked perfect, and would have been, but I just can't get reliable throughput on 5Ghz. Typically for me, the 5Ghz connections is much slower that the 2.4Ghz.

    I've also seen my throughput drop after a few hours on a long data transfer between two Macs on my local network. After a reboot of the base station, all is well again, albeit slower than the same connection on the 2.4Ghz band. I'd use 2.4Gzh all the time, except that with all of the competing use of that band, my range is severely limited.

    I'd really like to see a fix for the

    I am not convinced that this issue is specifically related to the late 2009 model.

    I have an earlier "gigabit ethernet ports with n" but not the one that supports "Dual" n and g. in fact I had 2 and an express.

    my plan was to mesh them all together an have fantastic N coverage on 5GHZ, problem is that it never worked well, the drop outs were REALLY bad, I assumed that it may be due to the walls in my house.

    I resorted to 2.4GHZ and things improved, but the coverage and more importantly throughput is FAR better with my ADSL routers (Thomson and Draytek)

    I bought the late 2009 model to try and improve things an it is no better, still bad throughput.

    I hope they can fix this as I really feel I have been sold 3 lemons and they are not cheap! I have a feeling though that Apple will release another model that will be "even better" and not address the ones we have.

    I'm with you on this one. I am pretty sure they won't fix anything with firmware due to all those hardware changes (read: cuts) they made with this version. I'm glad however, that this thread is getting more and more publicity last few days. We need to do something to fix this problem. If nothing else, hope for a recall and return our units so Apple can replace them at no cost at all, whenever new (fixed/improved) ones are out (like that's ever going to happen).

    I have one of the older model TC's as well as a couple of AE's. The 5GHz mode has always been as useless as t*ts on a bull. Unstable, slow and problematic. I try the 5G band every time there is a software update but to no avail. Have basically given up on an Apple fix. Maybe all of this commotion will catch their attention. Not holding my breath however.
