My WiFi signal takes 60 Seconds for MacMini to see

I just upgrades to Snow Leopard last week from Leopard. Leopard found and recognized my Airport Extreme as my primary WiFi very quickly after waking up/starting MiniMac. Now, with Snow Leopard, my MacMini sees a neighbor's signal fairly quickly, but I have to wait almost a minute for it to see my WiFi signal, and when I switch to it, the curved lines of my airport icon radiate out for a couple of seconds before I get a full five bars. My Iphone4 and my Ipad don't seem to have any trouble seeing the correct WiFi signal. Any ideas? Thanks.

You could try creating a new location in Network Preferences. Failing that, I suppose you could try targeting some files in the /library/preferences/systemconfiguration folder. Possibly com.apple.airport.preferences.plist Try moving it to the trash.

I connect to the wifi source for five seconds and then disconnect for eight seconds. Then my ipad repeats. True for all wifi signal sources.

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.

My Pavilion G7 Suddenly Cannot Recognize WiFi Signal For Second Time In A Year

Hi All,
My Pavilion is about two years old and the
motherboard was replaced by HP while under
warranty.
For the second time in about nine months the notebook suddenly cannot recognize my router's
WiFi signal. This time if I do a system recovery I will have to reinstall 50 apps! I am trying to avoid this if possible. I understand that changing the bios settings may fix wifi issue but no idea how this step will affect (delete/save) files. Upgraded from WIN7 to 8 to 8.1. Please help. Thanks so much.
This question was solved.

1. Shut down your notebook.
2. Unplug the power to your router.
3. Unplug the power to your modem.
4. Wait at least 45 seconds.
5. Plug in the modem, and wait for it to come back online.
6. Plug in the router, and wait for it to come back online.
7. Turn on your notebook, and test your connection.
Reset the TCP/IP settings:
1. Go to your start screen/menu and type CMD.
2. Right click on the command prompt icon and chose Run as administrator.
3. In the window that opens type "netsh int ip reset resetlog.txt" without quotes, and press enter.
4. Restart your PC and test.
Reset the winsock catalogue:
1. Go to your start screen/menu and type CMD.
2. Right click on the command prompt icon and chose Run as administrator.

IPod 5th Gen doesn't find any WiFi signals after battery was dead for two days.

I recently bought an ipod 5th generation, it only has the selfie camera (no back camera).
My battery then ran out, and my iPod was dead for two days.
My iPod charging cable wasn't working, so i went out to buy a new one.
After charging it with the new cable, it would not connect to the internet.
My brother has a 4th generation ipod and his picks up and connects to the wifi signal we have here at home, but mine won't even pick up the signal, or any wifi signals period.
I looked around here on the Apple Support but found nothing that helped, I already reset my network settings.
Is there any way to fix this?

If not this
iOS: Wi-Fi or Bluetooth settings grayed out or dim
One user reported that placing the iPod in the freezer fixed the problem. A trick that works frequently with iPhones:
Settings > AirPlane Mode ON, Do Not Disturb ON
Power down and wait 5-10 minutes
Power up
Settings > AirPlane Mode OFF, Do Not Disturb OFF
If not successful, an appointment at the Genius Bar of an Apple store is usually in order.
Apple Retail Store - Genius Bar
Then
Does the iOS device connect to other networks? If yes that tend to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

I am sampling a signal at 1kHz for every 1 second. How do i average the signal for N seconds?

I am sampling a signal at 1kHz for 1 second. After one second of pause, i sample again for 1 second at 1kHz. If i do this for Nth time, how do i average the signal over the 1 second period?

Anyway you need to have the data to compute the average... and usually you don't get the data point-by-point unless it is very low frequency acquisition.
If it is the case, you have to update your 2D vector point by point and then compute the average after each new point (much slower process indeed). You keep say 20 vectors of data and fill in the data (1, 2...20) and then( 1,2..20), so you compute the average on the last 20 acquisitions
(don't forget the rating)

Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

Any suggestions for better wifi signal?

Hi everyone,
So I live in a bit of an older home, and since the walls are pretty thick and everything is compartmentalized, my wifi signal doesn't reach everywhere with the best signal. Below are the details of my set-up along with additional potentially-relevant information to provide context:
I have FiOS internet with basic cable (just downgraded from FiOS premium cable to save $$$)
The FiOS console is in basement
I have coax cables from the basement console going to: (internet) one router (the MI424WR Verizon FiOS Router) in office, and (cable TV) three TVs - one in the basement, one on 1st floor and one on 2nd floor.
My internet is only 2-3 bars in the location of the TV on the 1st floor. This is probably where we spend the most time using our devices when I'm not working, and would need the greatest signal boost.
Since I've downgraded to basic cable, I'd like to be able to stream on-line content in the location of the 1st floor TV without too much lag.
It would be very difficult to string an ethernet cable from my current router in the office to another router in the 1st floor TV room.
In the past I've tried relatively cheap [$30] wifi extenders with no help.
I've read a bit about installing a second wireless router, but not sure if I can do it by just splitting the coax going to my 1st floor TV into another wireless router without an ethernet cable from the office-router. (I'm okay with technology, but am somewhat behind in my understanding of wireless networks).
I'd like to spend less than $100 (assuming I'd need to buy another router - any recommendations?) to do it, if possible.
All suggestions (including non-second router recommendations) are greatly appreciated!!! Also, details on how to hook up the configuration would be especially welcomed. Thanks again and have a happy holiday!

Hi jsk2,
Thanks for the suggestion. No, I haven't tried to move the router to the 2nd floor. Is that supposed to improve the signal house-wide? The 2nd floor coax is on the opposite end of the house of the 1st floor coax.
Also, might be a really stupid question, but can the coax cables be used interchangably? (ie: the coax for my TV can be used for the router, and the coax for my router can be used for a TV)?
Thanks!
You don't mention what your tier is but I assume it's under 100mb?
any of the coax connectors can be used for tv AND router by adding a splitter - up to a max of 8 I believe.
Go onto ebay and get a couple of old fios routers and add one on each floor
Of course using ethernet would be a far better coice but I guess that's not an option

How to add a second router as access point and wifi signal extender

Previously I had 2 linksys routers and was able to configure them as one in separate areas of my house. I think it is called cascading. The 2nd router acted as an ethernet switch with 4 extra ports and it provided a wifi signal to areas of my house that previously had a weak signal when I used only one router.
I have since switched to an Airport Extreme as my main router. I can't seem to get the same configuration with the linksys router, it is Model E1000 and has an "N" signal. The Linksys E1000 I think is the newer model of the old WRT54G Linksys. I can't get it configured to work. I have searched high and low on the internet and can't find anything simple enough for a novice to understand. I did read something that I may have to assign a "DHCP Reservation" on the Apple Extreme. I couldn't figure that out.
Can somebody please offer some guidance on how to get this to work?
Thanks

You have two routers producing two networks with the same name, so they will show up as two networks on any type of scan by a wireless utility. This is normal.
If you had used two Linksys devices, they would probably show up as one network, not two. Linksys has a feature that allows this to occur, but this is not true of Apple devices.
As long as the wireless network name, wireless security and password match up between the two routers, the two networks will behave as if they were one. As computers change location, they will automatically connect to the wireless access point with the strongest signal.

Why does my macbook pro retina take 30 seconds for me to use it when i open the lid?

For some reason it takes my macbook like 30 seconds for me to use it when i open the lid. I cant move the mouse or anything until like 30 seconds go by is that normal or something wrong? Its the new macbook retina display and never had this problem when i first got it.

Are you running any applications when you open the lid, specifically any applications that are heavy on GPU usage such as iMovie or Photoshop?

Can I set up to connect 2 or 3 airport expresses to have a stronger wifi signal for a larger area?

Theoretically yes. It will really depend on your situation. Please review the following Apple Support article to understand what is possible with the AirPort base stations and post back with any questions or help in setting up your extended network.

After minimizing it takes up to 5 seconds for home screen to load

Galaxy S3, Android 4.3: After minimizing, it takes up to 5 seconds for the home screen to load. The screen is empty, without icons or widgets (not black - just completely empty). Seems to be Firefox specific: Chrome and other applications are not affected by this. Highly annoying. Can this be fixed?

I have an HTC Gingerbread device, and it has a problem with several different programs that if you use the Back button to exit Firefox and some other apps to the home screen, it crashes (white screen with HTC logo) and needs several seconds to rebuild. In my case, this seems to start at some point in a session, and then continues until I restart the device.
So I don't think this is necessarily specific to your build of Android or the Samsung shell. I'm not sure what causes it. Since you have a popular device, you might check a forum like the following to see whether anyone has more insight there:

It works fine for a while then the iTunes account vanishes from 'computer' menu TV screen. Full Wifi signal on both devices so can't think what could be causing it to happen. Any suggestions please?

Sorry, I updated another thread I was a part of but didn't update my own thread.....ughhh!
I updated all of my ATV 2's and 3's to the latest firmware when it was released and have been problem free since. I do believe the major issue of not being able to connect after a period of inactivity has been corrected with the latest ATV firmware.
I can look at my network connection table using "netstat -an" in a CMD window and I do not see the massive number of connections I saw before the update.
Here is a link to the other thread I was referring to above:

Resetting your settings
You can also try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your device settings again.... All of the settings in the settings app will have to be re-entered. You won't lose any data, but it takes time to enter all of the settings again.
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears. Apple recommends this only if you are unable to restart it.
Or if this doesn't work and nobody else on the blog doesn't have a better idea you can contact Apple.
Here is a link to their contacts with most of the information below.
