Wireless Network always closing down

Why is it that I always have to go through diagnostics in preferences to get my wireless network back up and running? It use to remain open for activity all the time.

Are you running Leopard on your systems?
I have my Mac Pro running 10.5.1 and my MacBook Pro running 10.4.11. The desktop suffers from the same issue you are describing. The internet connection just simply times out, or is just plain slow. I ran multiple speed tests to confirm it's my computer. I have cable internet, and the speed tests fluctuate up and down, but well below what I was normally getting.
I've had my AirPort Extreme (802.11n) base station swapped out for a new one, new AirPort card in the desktop, and the issue prevails. I have also erase and installed Leopard, to see if something might have been corrupted.
The funny thing is, if I connect it to my AirPort Express (802.11g only for iPhones) that's hard wired to the AirPort extreme, the internet connection does NOT die out AND the speed tests are normal.
So this leads me to believe that something has changed in Leopard's handling of 802.11n with Mac Pros. This was not happening for me in Tiger when it was still on my system.
Let's hope the next OS update patches things up.

    Have a 802.11n time capsule, the range of the wireless network has shrunk down to nothing over last few days. Used to be able to use wireless network anywhere in house, but now can only use in my office. Will not connect to iphones, ipad, itouch, or notebook. Worked fine last week, but over weekend just started having issues.

    It is very possible that you may have some form of Wi-Fi interference that has appeared recently that is preventing your Time Capsule (TC) from providing a clean RF signal.
    I suggest you perform a simple site survey, using utilities like iStumbler, or AirRadar to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible. Look for other Wi-Fis that may be operating nearby. Note those with the strongest signals and which channels they are operating on ... then change the channel used by the TC to be at least 3-5 channels away.

  • Unable to reconnect to wireless network after closing lid on macbook pro

    After installing recent software updates, I am unable to reconnect to my wireless network when I close the lid on my macbook. It says that it is "connected", but I can't access any website, check e-mail or ping any external server.
    I've never had a problem before, but now that I've installed software updates in the past few weeks I noticed the problem.
    Anyone have any ideas?
    MacBook Pro (Intel)   Mac OS X (10.4.9)  

    which ultimately means apple didn't do enough testing before releasing the last patch
    This is not always, and may not be, the case. What many don't realise is that many 3rd party developers stray from the 802.11 series specifications in an attampt to boost speed and get one up on their competitors. For instance D-Link, amongst others, use a short preamble setting by default in some of their routers to improve performance. However, this is non-standard and when it comes across wireless network adapters that don't support this then you have problems. They assume that their network adapters are being used for "maximum speed and compatibility". Whether Apple should or should not support a short preamble is another subject altogether.
    However, I do agree with you in that Apple should put more work into their Airport software.

  • Securing my wireless network slowed me down

    Hello,
    I have just secured my wireless home network (WEP).  I am not really concerned about advanced hackers - I just do not want curious neighbors getting into my shared files.  I have two wireless laptops and one wired desktop.  The network works great in that I get excellent signal strength.  But now websites are not loading well.  Especially technical sites (like linksys or email).  Craigslist, say, loads fine and quick.  It is the same with my desktop - this is curious to me.  My unsecured network is still ghost-ing and when I connect to it - the pages load just fine.  Then when I connect back to the secured network - its slow.  I switched to WPA - same thing.  I switched back to unsecure network - same thing.  I have run virus software - it seems i'm clean.
    Please - any help would be great!
    Thanks

    Whats the model number of your Router ?  Assuming you have a G series router.
    I think you need to make some changes on your Router, Follow the setups below and i think once all the changes have been made on your Router i think it will work perfectly fine. 
    Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter...Leave username blank & in password use admin in lower case...
    For Wireless Settings, please do the following : -
    Click on the Wireless tab
    - Wireless Network mode should be mixed...
    - Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network...
    - Set the Wireless channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
    For Wireless Security : -
    Click on the Sub tab under Wireless > Wireless Security...
    Change the Wireless security mode to WEP, Encryption should be 64 bit.Leave the passphrase blank, don't type in anything...
    Under WEP Key 1 type in any 10 numbers please(numbers only and no letters eg: your 10 digit phone number) and click on save settings...
    Please make a note of WEP Key 1 as this is the Security Key for the Wireless Network...
    Click on Advanced Wireless Settings
    Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"...
    Now see if you can locate your Wireless Network and attempt to connect...

  • WRT54G - wireless network listing gives me two automatic choices.

    let me explain.
    On my "view wireless networks" are I used to connect to a basic connection called Linksys. This is the SSID that the router names by default. This connection always said excellent in the signal strength area.
    Yesterday I noticed my internet was disconnecting itself alot and the signal strength said low or very low with around 9-20 mbps. I looked at the wireless networks and the one I connected to was unsecured. I had secured it about 3 months ago so this confused me. I messed with a few security setting on my routers configuration page and noticed they weren't doing anything to my router.
    I re named my SSID, turned the broadcasting off then back on and a new wireless network appeared. It had 54 mpbs and excellent signal strength like the one I've always had.
    Heres the problem though. The "linksys" SSID automatically makes me connect to it when I log on my computer. Even after I went to advanced setting and deleted it. not only that my internet is alot slower and im getting disconnected around every 30 mins. This never happened before. I'm wondering if its possible that this myserious second network connection could be the source of my problem.
    Also, my router is connecting to a 802.11G Wireless-G adapter.
    sorry if the post was a bit long, wanted to eliminate all variables.

    As I understand , You have your new Network configured on
     the Router, with a new SSID Name, and WEP Key.
    Then You could try this :
    Powercycle the Router for 20 Seconds. Restart the Wireless
    Computer.Once the Computer has restarted, [ if it's a Windows
    XP System ] , click ' start ', type services.msc, press return,
    you could find Services - Local Screen . Scroll down, and find
    Wireless Zero Configuration, Right click on it, click restart.
    Once done, Close all the Screens, click ' start ' Navigate to
    Control Panel, Go to Network Connections, Right Click on
    Wireless Network Connection, and select Properties.
    You find three Tabs  - General , Wireless Networks and
    Advanced, don't you ? Click on Wireless Networks,
    Check ' Use Windows to configure the Wireless Network
    Settings ' and down below, Under Preferred Networks,
    Highlight each of the names individually, and click remove.
    Once done, Click OK, Right click on Wireless Network
    Connection, Select ' View Available Networks '
    Select the name you 've had configured on the Router,
    Click Connect,
    Type in the WEP Key, the 10 Digit Number,
    Confirm it,
    Once Connected, Check the Online Connectivity.
    From now on, the Computer will consider your network
    as the Most Preferred Network to associate with..
    Kindly try this, and if the Problem persists, send a text
    across for any further assistance
    Thanking you,
    Shriraj.

  • Suddenly can't connect to home wireless network

    All of a sudden I can't connect to my home wireless network - always has worked perfectly.  Now I get a box asking for the password, and although I type it in correctly it keeps saying "incorrect password."  I thought I'd delete it and re-establish it, but it doesn't show up in the Managed Network settings.  Any ideas what is going on?

    On the problem computer, go to Control Panel > Printers and delete all instances of the printer.
    Next, print a Wireless Network Test from the front of the printer (Network menu).  Note the printer's IP address.
    1. Make sure the printer is turned on and connected to your network. Verify that you can access the printer's internal web page by browsing to its IP address before continuing.
    2. Click >> Start >> Control panel >> Printers.
    3. Click the Add a printer
    4. Select Local printer
    5. Select Create a new port and select Standard TCP/IP Port and click Next button.
    6. Under Device type, select TCP/IP Device. Under Hostname or IP address, enter the printer's IP address. Click Next.
    7. Select Hewlett-Packard from the list of manufacturers and select and select your printer model. Click Next.
    If your printer model was not listed, then select Have Disk, browse the HP CD that came with your printer and select the first file that starts with hp and ends with inf. Click Open then OK. Select your printer model. Click Next.
    8. If you are asked, use the currently installed driver.
    9. It will ask for the Printer name -- enter a new name or use the existing one. This will be the name of the printer that you select from other applications.
    10. You may be asked to share the printer. Choose NO.
    11. The Print Test Page box appears. Go ahead and print it.
    12. Click Finish.

  • U350 crashes my wireless network.

    Just had my U350 with windows 7 delivered today.
    Very excited, but very confused.
    After running through the set up, I encountered a problem. My wireless network immediately shuts down and refuses to stay connected. I have tried playing with every piece of software for networking installed to no avail.
    I can't use my new laptop for fear of kicking everything from the computer I'm writing on now, to my iphone off the network trying to connect!
    I know for a fact it's my U350 that crashes my network since it only happens when I try to connect with it.
    Any one have any suggestions on what to do?

    it seems readycom just makes some issues on systems if you don't count this, it is useless.
    you can download the driver from here.
    also try manual ip instead of dhcp.

  • Cannot create wireless network. I use the 2wire modem of att verse...

    I cannot creat a wireless network connecting the time capsule to the 2wire att uverse modem....

    Need a bit more info..
    You cannot create a wireless network that joins another.
    And you cannot extend a non-apple wireless network.
    If you want to join the TC to the existing wireless network.. old down the options key when you click on options for wireless mode.. now if you are on lion you need 5.6 utility.
    Once the TC joins the network it becomes a simple wireless client with everything basically off.
    A much better option is to plug the TC into the 2wire with ethernet.. and bridge the TC.. it is then accessible from the 2wire wireless network or you can create a second wireless network or a reinforced one.
    Bridge is under internet tab in manual setup.. connection sharing.. off bridged mode.

  • Wireless network connection issues since last security update

    Hi All,
    I've run into an annoying problem since I applied the last security update.
    I've locked my wireless network a home down pretty tight. One of the settings I set is the "don't broadcast SSID" for that tiny bit more of security.
    Since the last security update my MacBook doesn't connect to my wireless anymore. There are two ways I can get it to connect:
    1. Manually tell it to connect by resupplying the SSID and the WPA key info.
    2. Reconfig my wireless to show it's SSID, connect, tell wireless to hide it's SSID. I then lose connection but have a few seconds that the MacBook "knows" the wireless exists and I can select to connect to it from the wireless icon in my top menu bar.
    Anyopne run into this issue and know a fix? Getting annoyed of having to do this every time I boot. Especially as I needed to change my WPA key into something I can remember instead of the 56char key I used to have
    thanx

    Thanks Eric! Since changing this setting last night, all has been ok

  • Wireless Network Does Not Always Connect Successfully on HP ENVY 5644

    Just purchased a new HP ENVY 5644 device to replace an existing my HP Photosmart C4380. Powered the new device on for the first time and ran through the initial setup using the integrated touchscreen. Everything seemed to go both easily and smoothly, without any errors and even connected to my home wireless network on the first attempt.
    I next tested both printing and scanning features, each of which provided extremely pleasing results and good performance over the wireless network.
    Unfortunately, this is where my happy story ends and the trouble begins!
    Having initially setup the device in a temporary location, I correctly powered down in preparation of relocating it to its final resting position. Although this was to be in a different room of the house, it was in fact closer to the wireless network router itself. In reality, we are talking a very negligible distance as the 2 rooms are actually back to back to one another. So now with it in the new position and connected to a power outlet, I switched the device on once again. The device powers up and the blue LED indicator which signifies the wireless connection status, continuously flashes blue rather than a steady solid blue. The flashing blue indicates that the device cannot establish a wireless network connection. If I use the touchscreen to investigate the issue I find that there appears to be an Authentication Problem and the message details are Incorrect wireless password (WPA) entered.
    Why has this happened? Nothing has changed, all I did is move the printer into another room!
    Believing what the touchscreen tells me, I decided to run the Wireless Setup Wizard once more to affirm the wireless network settings. As expected, it manages to find my home wireless network without any issues and then requests that the password key is entered. I therefore enter this correctly and press apply. It is at this point that the device attempts to make a connection to the network, which unfortunately fails, returning the above error message. However, I know that I entered the password correctly, in fact there is an option to show the password you have entered prior to attempting the connection, which upon checking confirms that the password I entered is the correct one!
    So why does it not connect?
    I have tried switching the wireless feature on and off several times via the touchscreen interface but this did not resolve the issue. The only way to get the wireless connection back online is to keep switching the device on and off again until the wireless LED indicator stays on solid blue. For no apparent reason, the wireless connection seems to have a mind of its own, only successfully connecting to my wireless network when it wishes to!
    I do not have any issues with the numerous other wireless network devices I have in my home, from multiple manufacturers and even located in other multiple rooms of the home. I know my wireless network is good and I know my wireless password like the back of my own hand, so there is no chance of this being incorrect. This is purely a problem for the HP ENVY 5644 device itself, which can be confirmed by the fact that if I switch it off and on again, it might decide to make a successful connection even though I did nothing to its own network configuration nor to my own wireless network configuration itself.
    Wondering whether or not it might be some obscure incompatibility between my wireless router and the HP ENVY 5644, I tested the device with another spare router that I have, which was also from a different manufacturer but sadly the result was the same, the HP ENVY 5644 only connected when it wanted to and would only establish the connection to the wireless network upon switching on the device. If the connection fails, it will never connect to the network unless you switch it off and then back on again, which might even require to be attempted several times before successful. Once connected, it appears to remain connected and then functions really well.
    This behaviour is not acceptable and I’m sure this can’t be too healthy for the device itself to be switched on and off again in such short cycles. Otherwise, on the whole, as I said earlier, I am very happy with the product.
    Can someone at HP tell me why this is happening or suggest what else I need to look for or consider.

    Spoke with HP engineer the other day. I explained what was happening and they suggested doing a factory reset and then setting the IP address manually rather than using the DHCP of my home wireless router.
    I wasn't too happy about that as everything was setup nicely and working, with the exception of the WiFi not reconnecting on every power on. I had also gone one better in fact, by adding a DHCP reservation within my router using the MAC address of the printer. This in effect is the best of both worlds as the printer will be given the same IP address by the router every time it requests one.
    We agreed to leave things as they stand rather than factory reset the printer and that I would now power off the printer everyday. For the past 4 days, the printer has reconnected to the WiFi upon every power on. This is great news.
    I have a call scheduled with HP in a few days time to discuss how things have been going. If all continues as is, it would appear than specifying a DHCP reservation in the wireless router resolves the issue. Whilst I await the next call with HP, I am continuing to power on and off the printer on a daily basis.
    Watch this space!

  • I installed my new Apple TV and successfully completed the configuration (Wireless network, Apple ID, and others) yet I am always in the Computers and Setting page- can't move to the main page – any idea on what and how, please?

    Hello, I installed my new Apple TV and successfully completed the configuration (Wireless network, Apple ID, and others) yet I am always in the Computers and Setting page… can’t move to the main page – any idea on what and how, please?

    Welcome to the Apple Community.
    Unfortunately, a number of users appear to have encountered this problem. Some of these users have reported that the problem just disappears the following day or shortly after. Other users have found various other solutions to this problem.
    Firstly, are you receiving any date and time errors when you turn on your Apple TV?
    Check that you are properly connected to the Internet, by ensuring that you have a proper IP address and not one starting with 169. Also check that your location for the iTunes Store is set correctly, if so you might try changing it and then changing it back.
    If the problem persists try restarting the Apple TV by removing ALL the cables for 30 seconds, or resetting it using the reset option under general. You should also try restarting your router, or if this doesn't work you might like to try a restore.

  • Why does Airport Express slow down my wireless network??

    Hello, guys! Here I am again, seeking for help...
    Ok, so here's the situation: my internet service provides me with 10Mbps. My cable modem is hooked up to a 4-month old Airport Extreme in my home office, two walls away from the living room, where I'm typing from now. Internet's wireless speed in this living room has always been about 10Mbps, barely any loss when switching my signal from cable to wireless.
    I then decided to buy an Airport Express in order to extend my wireless network, since I want to work in a room far from this living room and with Airport Extreme alone I got no internet signal there.
    Ok, so I installed the Express right at the living room (I can say it's pretty much at the middle of the house) and now I got full internet sign at the far room, great!
    HOWEVER, my wireles speed has been cut by half!! At this very same living room where the signal was 10Mbps before I installed the Aiport Express, it's now - at the very best!- 5Mbps!! Needless to say that it's even slower at the far room it was intendend to extend the signal to, but that was kind of expected.
    *But why does it cut in half my internet speed at the living room if Airpot Extreme IS delivering 10Mbps at that point of the house??* Am I not setting it up properly, how can I solve this??
    Thank you so much for any help you can give me!
    Cheers,

  • Always have to select my wireless network...

    On my powerbook I can't figure out where I can tell it to automatically connect to my wireless network when I boot up - I always have to go up to menu bar, click on the wireless icon and select my network. There must be a way to tell it to always select it, but I sure as heck can't seem to get it work!

    I have the same problem. I reviewed the knowledge base entry, but I only get options for "automatic" and "preferred networks". I lose th connection constantly and can only re-establish by manually selecting the network name from the airport pulldown list.
    Ideas?

  • My apple extreme wireless network is working fine with the macs but ios devices (iPhone & iPad) will not connect. I can see the network though. Everything was working until the ISP went down. Any suggestions?

    My apple extreme wireless network is working fine with two Macs but ios devices (iPhone & iPad) will not connect. I can see the network and it's telling me I'm connected but Safari says I'm not connected to the internet. Everything was working until the ISP went down. Any suggestions?

    Thank you, I've tried the support tips (resetting the network, checking security settings, etc.) and rebooting the network devices several times to no avail. I've actually been working on this for several days (when I can afford to have the network down).
    What I have to determine is what has changed in the setup...from when it WAS working just fine with all devices.
