Airport Extreme dropping connection

Been having the Type 1 problem (wireless connection dropping) intermittently for months now. I have a Airport Extreme (single-band model) on firmware 7.5.2. Downgrading to 7.4.2 didn't fix it. Tried downgrading to 7.4.1 and that seemed to fix it until about 24 hours later when it started happening again. Tried downgrading to an even older version, but that didn't seem to make a difference. I'm now back on the latest 7.5.2, but the wireless connection is still very spotty.

Turning off wireless encryption seems to fix the problem, but I can't risk leaving the connection open.

I tend to agree with you. I never had a problem until I moved here where my only choice for Internet is Comcast; the same ISP you had no problem with. My service has been very stable since around Christmas, so I'm hoping Comcast changed something

Hi- I am going on record as having this problem also. I just posted something on it- but since this seems to be one of the "main" threads on this issue going- I'm pasting my post here:

+I've been having this problem off and on for several months- I've read lots of posts here with a wide range of different fix suggestions. Any help from somebody whose successfully troubleshot this?+

+My Gear: Broadband Cable Modem -to- Airport Extreme (802.11n) via ethernet.+
+Airport -to- iMac, a Windows laptop, and iPhone via WiFi.+

+My problem: All 3 clients have the same issue: The connection drops every 8 seconds. I'm connected to my network, all bars black- then I get dumped, "looking for networks" for a second or two, then it re-connects. This happens every 8 seconds like clockwork. Internet connection, e-mail, iDisk- everything affected.+

+What I know:+
+1. It is not the modem. Connected directly to the modem with ethernet, everything is fine.+
+2. Restarting airport does not help.+
+3. I don't think it's interference. The very first time I connected my Wi-Fi, I had this problem. I moved a cordless phone to the other side of the room, and the problem went away...for a few weeks. Then it came back. I did all the usual stuff, restarts, etc. nothing helped for a few days. Then suddenly the problem spontaneously went away. Been okay for about a month or so- now it's back with a vengeance.+

+I haven't changed service providers...BUT:+
+When I recently re- setup the airport while ethernet connected, Airport Utility told me that the modem did not have a valid IP address. I haven't changed anything. Modem is still the same.+
+How do I change the IP address? Can I do this manually? Would this cause signal drops every 8 seconds?+
+Judging by the posts on here- this seems to be a common problem. However, I haven't seen any common solutions. Help +

Any further news on this? Constant trouble-shooting is getting annoying. Assuming we are all talking about the same problem- I can safely say the issue is with the AEBS- and not ISP.
Here's a weird thought: I was looking at the dates of all the posts in this thread and relating them to when people were saying they were having this problem. They more or less correspond to my own time-line. Could this problem be somehow linked to solar activity?
Anyway- please keep this post alive until a solution or new firmware fixes this.

I've downgraded my firmware to the latest 7.3.* and it's been pretty reliable for the past month. Only lost wifi one time since then.

Yeah- Thanks.
I've been reading about this on here. I'll try this over the weekend and report the results here.

As seen via remote connection to my client's Airport Extreme Base Station, the log indicates that the iMac's disconnection occured following clock synchronization. See below:

Mar 21 23:05:48 Severity:5 Clock synchronized to network time server time.apple.com (adjusted +0 seconds).

The iMac appears listed among Wireless Clients and DHCP Clients list, but users cannot access the internet.

Hope this is useful info.

I was having similar problems, internet slow or dropped, or not connected at all. Tried some of the many fixes mentioned on the net, nothing worked. My son, not a computer expert, said the Airport unit seemed rather hot, so I put a fan in front of my setup (Airport and cable modem, also 2 hard drives connected to the Airport wireless router). Voila! Everything works now. Could this be something internal (like a resistor) going bad? Has anyone seen anything about this possibility?

Downgraded the firmware. Everything is fine now.
Interesting: The other night I downloaded and installed the latest OSX update, after which, when I re-started, immediately had the same connectivity issue.
My airport "automatically" upgraded to the newer firmware. So, I downgraded again and the problem vanished.

Hey there pardon my noob question but where can I find old firmware versions? I'm having the same problem. Cheers.

In Airport Utility, Hold down the Option key as you select "Check for Updates…" from the AirPort Utility menu. If you see a button that says "Show Details," press it. You should see a list of all available firmware. Click the one for your device.

I have my AirPort Extreme (late 2010 Dual Band) connected to my Innoband ADSL2+ modem. The modem is in bridge mode, and the AirPort extreme connects via PPoE. Intermittently, I experience disconnects throughout the day. The annoying errors are as following:

Downgraded to 7.5.1 and so far all is ok. 7.5.2 in conjunction with whatever system updater added recently just wasn't working - I was getting disconnected and losing DHCP every few minutes. The downgrade seems to have helped. Odd thing is it didnt happen immediately after the firmware update, nor after the system update to 10.6.6, but rather some subsequent change must have triggered it this week. I also updated to 10.6.7 today, so maybe that combination did the trick? Fingers crossed, but anyone experiencing these problems could save a few hours of troubleshooting by simply reverting to earlier airport software. You have nothing to lose and may save yourself some grief.
