Airport Extreme (802.11n) - Connection drops (no auto-reset)

Blush i used a PC with the intel wireless utility to scan what channels the surrounding networks used

It is not security related or interference related. I live in the country, seriously, 3 miles from the nearest town, 1/8 mile from the nearest neighbor who doesn't use a wifi network, etc. I also have no wireless security turned on at all (nobody to steal the signal).

I still have the problem where my computer drops the wireless connection, still sees the base station, then reconnects 30-60 seconds later. Check my previous post for details.

you're right, it's not security-related. The base station dropped out again three times this morning while trying to check email. I was grasping at straws.

The next straw to grasp onto: kernel panic? which might account for dropped connection and then attempts to reconnect a short while later (but which sometimes requires a resubmit of login credentials, sometimes not)?

I'm running Base Station version 7.2.1 with two MacBooks, an iMac, and a PC on my home network. Since upgrading to Leopard, I've been having intermittent Airport Extreme base station drop outs. I originally attributed it to my MacBook, but I've recently had both MacBooks and the iMac drop out of the wireless at the same time. The indication on the front of the base station stays green throughout.

I've been running the same machines on the same network with the same AE Basestation for months with very few issues. Over the last week or so, I've noticed a substantial increase in network issues. I suspect that Leopard is doing something odd, but I have no idea what. I know there was an issue with wireless several OS versions ago (10.4. somethin) where my MacBook would drop off the network. I'm hoping that patch wasn't accidently omitted from the Leopard Baseline build.

Anybody at Apple have any info on this? Sounds like this is developing as an issue. Anyone put this into bug reporter, yet?

Another "me too:er". Airport Extreme 802.11n 100mbit drops network connection. light goes to yellow and then back to green. The cycle takes about 30 sec. I think the problem escalated when I put in a Airport express as a member in the network.
The more things that are "connected" to the N basestation, make it cykle on/off.

I have 10.5 computers that are booth upgrade and clean install. Most of the connections are old "g" connections.

I really cant use internet, with this problem, because programs like Radioshift and Unison goes crazy when they loose internet connection while they are running.

Apple support is pathetic when they do the standard "reset NVram" routine. It is a problem with their N router / or leopard.

I was having the same problem as you(I think). I just got two 802.11n's two days ago and they started almost immediately to disconnect on their own. I am running the unit on the ngb mode and all I did was change the channel and the problem was resolved. at least for now anyways. It's been running now for one full day without any problems. keeping my fingers crossed x
crazy

I had the exact same problems with mine as well. I spent a few hours with apple tech support and they were not able to resolve the issue for me - so I exchanged for a brand new AEBS yesterday. Guess what? I still get disconnected after a few hours. Then I have to unplug and plug it back in and it works again.

I first started getting these connection drops when I started using Leopard 10.5 a few weeks back. I have sent feedback to Apple support but so far no fixes for this problem.

Any hear anything new on this?

Well I might as well chime in too.
I am having the same issues here. I have 2 APEs in WDS mode. 1 main and 1 remote. They were both loaded with 7.2.1 and I recently loaded them with 7.1.1 to see if it was 7.2.1 that was causing the issues. Same issues if not worse. I have a Mac mini, an HP PC, and a MBP on the network. This is frustrating Apple, please release a fix.

One thing to try is to select a fixed channel instead of auto on the router. I selected that last night, and it seems to have helped. I don't have any drop outs yet, but I don't have much use on it yet either. Just something to consider.

And, me too.

I took mine back to the store, and they pinged it for three days and said they had no trouble with it, so I needed to look at the forums. (Thanks!). They suggested it might be the vpn I use to connect to work but didn't have much further to suggest. At least I am not alone -- I lose connection but light stays green. Wireless and wired. Several times a day, need to plug/unplug to right it. What a pain. Not upgraded to Leopard yet.

It certainly does seem that VPN connections often trigger the problem for me, but it happens when I'm not on the VPN too. Having said that, my AEBS has now been up for 48 hours, which is a record for me. Who knows why, but for what it's worth, I turned off my DHCP reservations and port mapping. If it stays up for another 48 hours I'll start changing settings, but for now I don't want to upset the delicate balance that's allowing it to work.

another.... MINE TOO

have a macbook c2d and the network keeps on dropping around every 5-10 hours. have already replaced the airport card @ a store and still keeps happening.

other computers:

mac mini g5 leopard NO ISSUES
ps3 wireless NO ISSUES
wii ethernet NO ISSUES
dell laptop wireless NO ISSUES
voip router ethernet NO ISSUES

yet to hear about anything that is going to fix this

Yet another, ME TOO!!!

I can't get any work done between the internet dropping out and everyone in the building saying, "the internet's down again." LETS GET A FIRMWARE UPDATE!!!!! NOW!!!! LETS GO APPLE...at least a response!!!!!

I have the drop off, green light, requires restart issue as well. It has occurred since I bought the AEBS in September and continues under Leopard. It affects wireless and wired clients, intel, powerpc, and pc computers, and, as others have mentioned, occurs as often as a few times an hour or, if I'm lucky, as little as twice a week.

I hope this is solved. My AEBS would be a near perfect router if it wasn't for this hideously annoying defect.

I originally posted this to a different thread - but this seems the more appropriate place.

I'm having the same issue of dropoffs/timeouts - I thought it was the interaction of the Express and Extreme base station, but I took out the Expresses in my house and have the same issue.

Apparently it's either a DNS or IPV6 issue (or combination thereof)

All sorts of advice in other threads about downgrading to 7.1 or 7.1.1 (apparently 7.2 doesn't fix the problem) but since I bought my Extreme recently, I only have 7.2 local. Apple doesn't seem ok following other hardware sites example of leaving up old firmwares up "just in case".

Anyone know anywhere I can find a 7.1.1 firmware (down)grade?

And shame on you Apple, considering the number of posts I've seen about this. Pushing a "backrev" update with some busted security is better than leaving a broken firmware out there for, from what I gather in other posts, over a month and a half at this point between Dropped wireless/DNS/IPV6/Disk issues and the rest.
