internet connection loss after a few minutes

Is this the new AEBS n you are connected to? if so I've had the exact same symptons and so have many others, our other 2 Core 2 Duo have not had the same promblem.

I just upgraded to a 24 in. C2D it's been working now for 6 hours without interuption a record compared to the last one. ( it seems to me that the AEBS n does not like a mixed bag of cores)

Good luck I hope you solve your problem cheaper than I did, but what a great excuse to upgrade.

Hi John,

I posted a similar problem just the day before you did, and I haven't been able to figure it out either. The other reply noted that the AEBS might have issues with different cores, and that is also true in my case (PowerMac G4, MacBook Pro, and MacBook), but I have not been able to find any other patterns. I have lost connection when I am just working with the LAN connected G4 or when only the wireless MacBooks are in use. Sometimes I have held the connection for hours or just a few minutes. Very frustrating!

I will keep monitoring the posts though. Good luck.

Same problem here, but I'm not sure about the cores being a related issue. I have 2 Macs (PowerPC Mini and a Core Duo MacBook) connected via wi-fi, and 3 Ubuntu Linux PCs connected via wired ethernet to the back of the AEn (2 Dell servers and a home-built P4). All of these have lost internet connection at some point or another (I've only had the AEn for 6 days.)

The wired PCs seem to lose internet connection most often, usually after about 5-10 minutes after booting up. Sometimes one will keep the connection for hours, but I haven't had one NOT lose a connection yet.

The Mac Mini seems to be most resilient to this problem -- it's lost internet connection only once. The MacBook is somewhere between the PCs and the Mini -- it keeps a connection most of the time, but has lost it more than once.

The odd thing is -- the internet connection loss is not simultaneous. I can be working on one PC and have no issues, while my wife suddenly loses the connection on another.

The AEn base station replaced an old SMC wireless router that never had these types of problems. The current setup is pretty much the same as it was with the SMC -- it was a one-for-one router swap with no changes to any of the other hardware, cables, etc.

I'd be grateful for any advice.

AirPort Extreme (802.11n) Mac OS X (10.4.9) Other OSes: Ubuntu 7.04, Ubuntu 6.06

Suffering the same intermittent connection issues here also, seems to have started after apples latest batch of software updates of which Airport Base station and Airport Extreme updates were a part.

Also affecting my linksys router to which it is connected via ethernet.
Again, i had no problem prior to the updates.

I'm having the same exact issue. I just got my second Airport Extreme after sending the first one back. All configured, using WPA2.

Every few minutes, the connection drops.

I've tried Interference Robustness, all of the different channels, disabling NAT-MP, and countless other things. I live in a condo building with lots of other wireless networks. Not sure if it's interference from someone else or not.

I used to have a Linksys B router, and it never once had a problem. This Airport Extreme seems like a whole lot of trouble...

Any additional advice would be great.

Here's a weird one I can't figure out. My internet
connection over my network only seems to last for a
few minutes. I've noticed that when I'll leave it
all night, and all day, once I return home from work,
I can get on the internet for about 10 to 20 minutes,
then it stops working.

I just installed my AEBS (802.11n) and the newer AirPort Utility that came with it, and configured it without any problems. I am using my PowerBook 17" (Aluminum G4) as the only computer it connects to, and have had several periods of no internet connectivity after a few minutes of idle network usage. It seems to "timeout" somehow. As long as I use the network, it stays up. Once I walk away from the PB for about 10 minutes or so, there is no internet connection.

The PowerBook continues to see the AirPort, and the AirPort status LED glows steady green, and shows up as OK in the utility app. I'm thinking this is a firmware issue. Does anyone at APPLE have an answer? I'm trying to use this in my new office, and need something that's reliable.

PowerBook G4 17" Aluminum Mac OS X (10.4.9) New AirPort Extreme Owner... not so happy!

Not sure what's causing this?
It's not as though the airport connection is lost as the signal strength is fine but simply no internet activity is possible without a recycle of the linksys or ABE.
If i remove the ABE from the equation and connect to my linksys all is well...
Not until apples latest updates did i begin having problems.

Connection was lost as i was typing this...

Same problem here. My computer (2.33MHz Core 2 Duo Macbook Pro) drops connections frequently, and looking at the airport strength bar, it is constantly resetting the connection, and the signal strength bars are all over the place, like it is constantly looking for the right setting. My wife's older Core Duo Macbook Pro (not a core 2 duo) has a rock solid connection on the same Airport Extreme 802.11n at the exact same time as I am having trouble. Absolutely no problems. My PC notebook is of course the worst and can't keep a connection at all.

All of this started after I upgraded from AEBS a/b/g to AEBS a/b/g/n. I've downloaded all the latest software updates including installing the AEBS a/b/g/n CD onto my laptop then updating that software.

Could it be that the newer AEBS is searching / switching between the 5GHZ and 2.4GHZ settings? My wife's older model airport wireless card is not 802.11n compatible)

I also noticed that as I was downloading updates today during a good connection time, my connection was rocketing along, but as soon as my wife logged on (but not downloading) and her laptop registered on our wireless network, my connection speed dropped in half.

I hope this is helpful in coming up with possible ideas as to the problem... Sounds like a patch is needed.

To think I just two days ago switched to a Mac after twenty-three years of using exclusively PC's (starting with a Tandy TRS-80) because Macs were so easy to network, among other things!!!



MacBook Pro 2.33MHz Core 2 Duo Mac OS X (10.4.9)

I think I might have a bead on this problem. Not sure if this is applicable to others as well...

I have three computers:

1. 13" MacBook
2. Sony TXN19P, running Windows Vista, joined to an Active Directory Domain
3. Shuttle X100, running Windows Vista, NOT joined to an Active Directory Domain (joined to WORKGROUP)

If my Sony joins my wireless network, the router connection drops constantly.

If my Shuttle joins my wireless network, everything is fine and dandy.

If my MacBook joins my wireless network, everything is fine and dandy...

..EXCEPT when I'm running Windows Vista in a Parallels virtual machine. The Vista VPC? Yeah, you guessed it...joined to an Active Directory Domain.

So far, I've tried all manner of troubleshooting (channels, interference robustness, the works). Windows Vista joined to an Active Directory Domain is the only one of the variables that consistently causes my router to power cycle and drop connections.

Thoughts?

I'm having problems even when there are no windows machines powered up or running on the network, only my MBP.

I can repro my situation every single time.

If I turn on my Parallels VPC with Windows Vista connected to an Active Directory Domain, my router power cycles and gets flaky.

If I keep it off, everything works just fine.

No windows running on my network now... just MBP. My problem must be elsewhere...

I missed this thread, here's mine:

My symptoms are a bit different (it generally keeps it connection once it grabs it) though it is very slow.

My problems usually starts when I boot or wake from sleep, the black bars appear after about 10 seconds, but Safafi says I not connected to internet (Network says I'm connected to internet via Airport, Airport Utility has an IP).

This usually stays like this for 30 seconds to a few minutes then Safari goes out (very slow I may add according to dlsreports.com speed tests).

MAKE SURE YOU MANUALLY UPDATE THE ROUTER FIRMWARE to 7.1
Open Airport Utility> Airport Utility (drop menu)> Check For Updates...

Hi

I am experiencing loss of internet connection when my MBP C2D goes to screen saver or sleep. I am using airport extreme connected to a cable modem. Before this I had 2 x express which were perfect - they had internet on and always ready. I am very disappointed with the AEB as it also seems to be varied in the bars for signal even though I now have AEB and 2 AE's and it should be perfect.

Has anyone found a soultion to this yet?
