Why is airport scanning so much?

Every couple of minutes airport's status will switch from "on" to "scanning". It will stay scanning for about three seconds and then go back to "on". Why does it find the need to scan for wireless networks when I'm already connected to my wireless router, which most of the time, is about 20 feet away from where I am, and gives me full connectivity??
While scanning I can't load pages, so if I time my browsing wrong and decide to change pages while airport is scanning, I have to wait about 5 seconds for the page to load.
Is there anything I can do with preferences or something like that to make it so that airport stops scanning once it finds a certain network (ie- my wireless router)?

Count me in on this problem as well.
I have two MB Pros.
They both drop internet connection at the same time and both come back on at the same time.
I have a linksystem with At&t.
But the weird thing is that my Toshiba will stay connected to the internet ALL the time.
When I open network pref it says that "iport has a self assigned IP address but may not be able to connect to the internet"
I have only one network set up. So I know all my settings are correct.
It's just ironic that they BOTH shut off internet at the SAME TIMES and come back SAME TIME.
One MB pro was bought in Dec 07
The other I bought just a month ago.
Sometimes I can power off my linksys like I did today and that will solve the problem. Other times it will just come back online on it's own. I dunnoooooo.
Apple needs to at least address the issue on the site.

Airport: scanning problem

this has been discussed in other threads as well, probably most extensively here
http://discussions.apple.com/thread.jspa?threadID=1397364&start=0&tstart=0
but these threads have been quite confused, often combining a mix of (possibly related) problems and have not provided a workable solution
the problem i'm having is that airport keeps scanning the network, causing an instable connection and loss of network connectivity.
my configuration is a macbook (mid2007), running 10.5.3 fully patched, and an airport extreme basestation, software version 5.7
the problem seems to have occurred after upgrading to 10.5.3. "seems to" as i don't a clear break-point, but i definitely did not have this problem under 10.5.2 and have made no other changes to the network settings of this machine.
all other machines on the network have no problem, the problem is limited my macbook.
also, i've had the same problem when i took the machine to a local coffeeshop and tried to hook up there.
because of these reasons, i find any suggestion to make changes to the basesstation no solution, a work-around at best while we wait for apple to fix this.
istumbler logs show me an airport.scanner.update entry at the sampling frequency of istumbler (1 sec is the highest frequency)
istumbler also shows that signal strength is around 80% and that there is no overlap in channels or frequencies with other available wireless networks.
the number of available wireless networks changes every 5 to 10 seconds
airport flow.app says there is no snmp response from the basestation (though i have to say i have not tested this app in a situation where there were no network problems)
it seems to me that airport scanning has gone loopy - too much, too long and too interrupting
while we wait for apple engineers to figure this one out, does anyone know if there is a way to set airport scanning frequency?
thanks!

If your problems have not been resolved, here is something else to try.
User/<username>/Library/Preferences/com.apple.airport.airportutility.plist - delete this pref.
Root HR/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist - copy this file to your desktop, then open the copy with TextEdit and delete everything after the first <dict> and before the last </dict>. Save the file on the desktop.
Now delete the file in the above SystemConfiguration folder - you will require administrator password.
Now copy the new file on your desktop to the SystemConfiguration folder - you will be asked to Authorise with your administrator password.
Now reboot and with a bit of luck, your problems will be over.
I am beginning to think that my problems were caused by migrating my applications from my old MBP to my new, as I notice that a number of preference files say the preference settings were migrated.

Why is Firefox writing so much data all the time?

I am running Windows 7 x64 and Firefox 8. In my Task Manager I display the I/O Write Bytes of all processes. I have found that Firefox is ALWAYS the Process with the largest amount of write bytes after it has been running an hour or so even though there are dozens of other processes there. The only Web page is Google and all of my plugins are disabled.
Why is Firefox writing so much data all the time?

Firefox may be updating the phishing protection database or do maintenance with other files like places.sqlite. It should stop at some point if that has been done.
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem.

Why did apple mail get much worse with lion osx? I can't add recipients without copy and paste?

why did apple mail get much worse with lion osx? I can't add recipients without copy and paste?

I went through updates on my three newest Macs this week. As I stated I'm talking about iTunes 10.5.1 (42). I am checking for updates now and I see 10.5.2 is now available. I'll know in about 15 minutes if this issue is fixed or not.
15 minutes later:
I must have updated this PPC G5 a day or two before iTunes 10.5.2 came out. I was able to update to 10.5.2 (11) and this copy/paste bug is fixed. I'm happy again.

Why is apple Australia so much MORE expensive than America!?

so tell me, Why is apple Australia so much MORE expensive than America!? i have been meaning to pick up a new imac.....and i saw that the exact same type of imac that i want i could pick up in America for a good $600 LESS.... you know, even though our dollar is HIGHER THAN AMERICA'S! *** APPLE!

Reasons:
Australian import duties

Without seeing an execution plan of the query it is hard to suggest something useful. Try insert the result of UNION ALL to the temporary table and then perform an aggregation on that table, not a CTE.
Just
SELECT CollectionDate,Bankname,DSLIPS AS DSLIPS,SUM(BN) AS BN,SUM(COINS)AS COINS FROM

Why am i using so much data since downloading IOS8

why am i using so much data since downloading IOS8

Don't know -- but you can do a little detective work by going to Settings > Cellular and look at the apps in the section titled "Use Cellular Data For." Each app that has used data will show the amount used since the statistics were last reset. If you tap on "System Services" at the bottom of that list it will show the details of system usage. You can reset the statistics at the bottom of the screen. Checking those numbers for a while should help identify what is going on.

Why when I scan it doesn't import because file already exists, i never scanned it before?

Why when I scan anything in my Photoshop Elements 8, it tells me that nothing was imported because a file already exists. I never scanned this photo before?? Please help!

It could be a file name duplication. Either the scanner creates some default file name, which it may have used before or you have assigned a duplicate file name. Try renaming and see if the Organizer imports it.

Why does AirPort Extreme stop working when I plug in a USB hard drive?

Why does Airport Extreme stop working when I plug in a USB hard drive? The USB drive has its own power supply. I've tried isolating the hard drive from Airport using a powered USB hub to no avail.

The USB port on the AirPort Extreme is borderline as far as its ability to supply adequate power to a hard drive. Another way of saying the same thing is that this is not a high power USB port, like you would find on a computer.
Your 2TB drive likely requires a bit more current than the USB port on the AirPort Extreme can supply. It is also possible that the drive's firmware may not support a network USB connection....only a "local" connection to a computer. Check with Seagate support on that possibility.
Try using a powered USB hub with the 2TB drive....and make sure that the drive is formatted correctly in Mac OS Extended (Journaled) or FAT32....which the AirPort Extreme USB port can accept.

Why do I get so much noise when creating a real instrument track?

Why do I get so much noise when creating a real instrument track?

Creating a real instrument track is a very silent matter normally. Once you start recording, you can indeed pick up noise - but that depends on what you're recording, how you're recording etc. - you didn't tell us anything about it.

Why do I have so much storage 'other' on my iPhone 5, ios7?

why do I have so much storage 'other' on my iPhone 5, ios7?

Hi: I had the same issue. I believe mine was due to the fact that I always installed software updates over wifi. I believe doing so did not remove the old software from my phone, which then took up space in Other. Here's why I think this.
Yesterday, I had 6.2 GB of Other (on my 16GB iPhone). Got the alert that a software update was available, but didn't have enough free space on my phone to update it over wifi. I plugged my phone into my Mac today and ran the update on iTunes and the Other went down to 2.1 GB. Note, when I previously updated software over wifi, it took about 3 minutes, today when I updated it by actually plugging into iTunes on my Mac, it took about 15 minutes. It cleared everything off my phone and reinstalled it.
I'm not sure if this is the only reason for the Other storage to be high, but if you update over wifi, it could be. Note: if you're not due for an update, you may want to try resetting your phone and doing a restore from iTunes. Be sure to back up your phone before doing this!
Hope this helps.

Why do i have so much other on my phone and how do i get rid of it

why do i have so much other on my phone and how do i get rid of it

Other is usually around 1 GB...
A ' Large Other ' usually indicates Corrupt Data...
First Try a Restore from Backup... But... if the Large Other Persists, that is an Indicator of Corrupt Data in the Backup... Then a Restore as New is the way to go...
