Wifi/3G wireless connectivity in general

i rarely see a ful signal on my wifi connectivity in my own home, whereas my girlf has a3GS and it never goes below full.
Also, my 3G signal is very patchy and only 'switches on' if i put into airplane mode on/off.
i don't SEEM to have these antennae issues, no matter how i grip the phone ( if i cover both and TRY, i do get bar drop.. but no dropped calls, and coverage is no better/worse than i was before on my 3GS on 02/UK.

    What kind of wireless router are you using? more importantly which protocol are you connecting with? Are you and wife connecting using the 2.4Ghz band? or do you have a dual band router that offers the 5GHZ band?  Are you both connecting vie 802.11 a/b/g or n?
    The best thing to do is to go into SYSTEM PREFERENCES and select NETWORK, then select AIRPORT and click on the ADVANCED button.
    Under the AirPort tab you should delete all the preferred networks and only add back in your network with the proper security settings and passwords.
    If you hold down the option key on your keyboard while clicking on the airport icon at the top on your macbook pro. you'll seesome data that will tell you what band and mode you're connecting at, as well as in an indication of signal strength (RSSI) if you write down and post back that information it'll tell us what's going on.

  • WRT160N - my wireless connection trashed after wife suspends her notebook

    My wife's Dell notebook recently died so she replaced it with a Macbook Pro running Win7.  Prior to her new notebook, everything worked great.
    But since she's gotten it, whenever she closes (suspends) her notebook, my wireless connection gets trashed for a minute or two.  It doesn't actually drop me from the network, but I get massive latency, DNS lookups stalling/failing, etc.  It's enough to disconnect me from any online game or service that I'm using that requires a steady internet connection.
    I'm running the latest firmware on my router and newest drivers I could find for both my laptop (Intel 5300 AGN) and hers (Broadcom 802.11n adapter).  I've done a full hardware reset of my router and re-set-up my wireless network (WPA2-Personal security), and it still happens.  This is 100% consistent, and while it appears to be specific to her new computer, it feels like the router is the one that's failing here.
    We're both about 9 feet from the router itself.   This does not happen if I hardwire my laptop to the router, so it's specific to the wireless connection.
    I can't seem to find any other instances of this happening searching around the internet.  Anyone ever heard of anything like this before? Any idea of anything I could change to try to fix it

    Open the router setup page and reduce the MTU to 1350 and click on save settings..Under the Wireless tab,Click on Advanced Wireless SettingsChange the Beacon Interval to 75,Change the Fragmentation Threshold to 2304,Change the RTS Threshold to 2304 and Click on Save Settings...Now,power cycle the router and check.

  • Will the AirPort Express Base Station create a wifi connection that will enable me to wirelessly connect to XBOX live on my xbox 360

    will the AirPort Express Base Station create a wifi connection that will enable me to wirelessly connect to XBOX live on my xbox 360

    Yes, but not in all cases with it provide your with an "Open NAT" condition that some on-line gaming require. However, for most Xbox LIVE access, it should work just fine.

  • Want stream Netflix to blueray via Airport Express wifi. The blueray finds my wifi but the wireless connection failed - said, Ensure DHCP server is enabled on router and restart router. Don't think I have DHCP server. Suggestions anyone?

    Want to stream Netflix to blueray player via my existing Airport Express wifi. The player finds my wifi but the wireless connection fails - says, " Ensure DHCP server is enabled on router and restart router." I don't think I have a DHCP server. Suggestions anyone?

    I can't speak specifically regarding LG, but the Whole Home feature on Direct TV (record a movie on one DVR and watch it on another TV in another location) just won't work with wireless, and I have a strong fast connection at 300 Mbps. Ethernet works perfectly.
    Few audio/video products will accept "n" wireless at 5 GHz. I suspect that your LG accepts a 2.4 GHz signal, which would top out at 130 Mpbs.
    If you are trying to stream High Definition video, especially at 1080P, my opinion would be that it is unlikely that you will be able to do so reliably using wireless.
    Perhaps another user who has figured out how to do this will post with some input.

  • Wireless connection between D-Link WiFi router and Time capsule stopped working

    We have an ISP provided D-Link wireless router (DIR-615) to which we wirelessly connected our 2Tb Time Capsule for back up and to connect a USB printer to out network. This worked perfectly for 3 1/2 years, until about a month ago, when the time capsule suddenly decided to go "off line". ie we could no longer access it or the printer via our wireless network. We had changed nothing - just one day it stopped working.
    We tried to get it back online with no success. As the 2Tb Time Capsule was almost 7 years old and had had some HDD issues in the passed, we figured it had got old and died and that it was time to replace it; so we bought a new 3Tb Time Capsule, thinking this would get everything back to normal.
    However much as we tried, we were also unable to get the new 3Tb Time Capsule to connect wirelessly to the D-Link wireless router. The Airport Utility did not show the D-Link wireless router or its wireless network, although we were (and are) able to see it in Systems Preferences>Networks from all our multiple devises. This in itself seemed odd. No matter what we tried, the Airport Utility would not find the D-Link wireless router and hence we could not add the 3Tb Time Capsule to the existing wireless network.
    At the end of the day we got fed up with trying to add the 3Tb Time Capsule to the D-Link wireless network, and connected it via a LAN cable to the D-Link router instead. We then set it up as its own network. Worked gerat. Having done that we thought maybe the old 2Tb Time Capsule might not have been the problem after all, so we tried extending our new 3Tb Time Capsule wireless network using the 2Tb Time Capsule wirelessly. This worked perfectly! And we are now almost back to what we wanted.
    So although we have a work around, this means now have 2 separate wireless networks as opposed to the original single wireless network where everything talked to everything else.
    Can anyone shed any light on any of the following:-
    1. Why the original wireless network connection between the D-Link router and the 2Tb Time Capsule just stopped working? Was there some software change from Apple that "decided" D-Link wireless routers were no longer secure; and therefore the TCs could no longer connect to them?
    2. Why it was not possible to extend the existing D-Link wireless network using the the new 3Tb Time Capsule?
    3. Is there is anyway that we can get back to a single wireless network based around the D-Link wireless router as the primary router connecting to the modem, where the 2 Time Capsules connect as "wireless satellite base stations"?

    1. Why the original wireless network connection between the D-Link router and the 2Tb Time Capsule just stopped working? Was there some software change from Apple that "decided" D-Link wireless routers were no longer secure; and therefore the TCs could no longer connect to them?
    A firmware update to the TC came along and you agreed to it without perhaps even noticing.. it then smashed your setup because Apple do not recommend the setup you were using and it is very poor.
    2. Why it was not possible to extend the existing D-Link wireless network using the the new 3Tb Time Capsule?
    Because it is such a poor setup that Apple have taken away your ability to choose it unless you know exactly what you are doing.
    3. Is there is anyway that we can get back to a single wireless network based around the D-Link wireless router as the primary router connecting to the modem, where the 2 Time Capsules connect as "wireless satellite base stations"?
    Yes, this I can help you with.
    I have several ways around the problem.. but the first one is.. why use the DIR-615 at all.. it is not a modem.. it is a very ordinary bottom end, poor single band slow wireless router.
    Why don't you simply remove the DIR-615 from the network completely.. plug whatever it is the ISP supplies you.. an ethernet connection from whatever that modem is you mentioned into the WAN port of the Time Capsule. And use the TC in some router mode.. same as the DIR-615 was setup.. dhcp or pppoe or whatever.. I doubt the TC cannot match it.
    If you have issues please post a few screenshots from the DIR-615 to show how it is setup from the WAN side.. and as long as you are given the username and password or whatever the ISP uses to authenticate then chuck out the DIR-615.
    Tell me if that is a goer.. if not we can work out a few other methods..
    eg. Simply turn off the wireless in the DIR-615. It is poor cf the TC and there is no need for it.. with the TC in bridge only use the TC for wireless as well as wireless extend with your old TC.
    Or setup roaming network where everything uses the same SSID.
    Then you will have one wireless network. And it won't matter what as long as it connects.. although IMHO this is not right as the TC is such a superior router now you are wasting your new TC.

  • Can some one translate these instructions D-Link DI-524: installation as wireless HUB/Bridge   General  ON ALL TYPES OF ROUTERS DHCP SERVER HAS TO BE DISABLED ON ALL TYPES OF ROUTERS UPnP ALSO HAS TO BE DISABLED OTHERWISE YOU CAN SEVERELY HINDER OTHER USE

    D-Link DI-524: installation as wireless HUB/Bridge
    General
    ON ALL TYPES OF ROUTERS DHCP SERVER HAS TO BE DISABLED
    ON ALL TYPES OF ROUTERS UPnP ALSO HAS TO BE DISABLED
    OTHERWISE YOU CAN SEVERELY HINDER OTHER USERS IN YOUR NEIGHBOURHOOD!
    Practical example: D-Link DI-524
    The DI-524 is a wireless router.Although the manufacturer doesn't mention this, you can also install this device as a wireless hub.Of course this is not supported by the manufacturer. Therefor you have nowhere to go in case of any problems Plug in the power cord of the DI-524. Do not yet connect the network cable!Search for existing wireless networks with your computer. Connect with the router.This can for example be done like this:
    Click the start-button (at the bottom in the left corner of your screen).
    Go to control panel
    Go to internet connections (you may have to choose classic representation first)
    You can now see your wireless network card, among other things. Right-click and 'View available Wireless networks'.
    Connect to the router. In most cases the router will be called 'default'.Check your IP-address: you get an IP address from the DI-524
    Go to the start-button
    Go to 'Run'
    Type 'cmd' and press enter
    type 'ipconfig' and press enter
    your IP address starts with 192.
    Surf to your router with your regular browser. For this you need the address and a password, which you can find in the documentation.
    In this case the address is 192.168.0.1
    Now you must secure the router. For this it is best to use WPA-PSK
    Your key is a randomly chosen sentence. Don't make this sentence too short.
    Warning: Case sensitive!
    You cannot reach the router anymore now.
    Go back to your network card via "make connection". Search for your wireless network again and make a new connection
    You are asked for a key. Supply this key the way you configured it in your router.
    Surf back to the router.
    Disable the DHCP server.
    !! YOU HAVE TO DISABLE UPnP ON ALL TYPES OF ROUTERS
    OTHERWISE YOU CAN SEVERELY HINDER OTHER USERS IN YOUR NEIGHBOURHOOD!
    for this, go to Tools, Misc and switch off UPnP
    Save these settings.
    If you do not have a D-link router, look up in the manual or somewhere else where you can disable UPnP
    Now you cannot reach the router anymore again.
    It is only from this moment that you can connect the router to the modem.
    Important: Use one of the 4 LAN ports. Never use the WAN port!
    Go to your network card via the control panel. Right-click and "Repair"
    Now you should get an IP-address in the range of 10.nnn.nnn.nnn
    If you still don't have 192... you've made an error. The DI-524 still functions as a router and this is not allowed!

    There are no Mac based instructions. The router is accessed and adjusted the same way whether you are using a Mac OS X, Windows or Linux. As noted in the other post it is done through your web browser which works the same from any computer. Even a Chrome Book.

  • How can I delete my old Laptop from my iPhone (iTunes Wifi Sync) and connect it to my new Laptop

    HI;
    I have an iPhone 4S Factory Unlocked, up to date (iOS 6.0.1). I connect it to my Laptop named "The Love" via USB and opend iTunes and checked Sync over Wifi to enable this feature. Everything works great.
    After a couple months I sold my Laptop and bought a new Laptop named "Raid", I did the smae steeps, connect it to my new Laptop via USB and opend iTunes and I checked Syn over Wifi to enable this feature and hit Apply, also I did the sync via USB cable and it works fine.
    Now I want to sync via wifi, so I went to General --> iTunes Wi-Fi Sync --> here my iPhone still showing "Sync will resume when "The Love-PC" is available", Okay I sold it!! What I will do! I stock! does this mean I will need to find my old Laptop and buy it back????!!!!
    I tried to do those steeps over and over, same result, my iPhone stock with the my old Laptop, It seems my iPhone liked my "The Love" Laptop
    My question is:
    How do I delete this setting? and connect it to my new Laptop?
    All the best;

    Well " even if I plugged it via usb" I meant that I did all the spteps, connect my iPhone via USB, Open iTunes, Check on Sync this device via WiFi, click on Sync, Unplug the iPhone.
    Again I DO NOT HAVE AN ISSUE WITH THE USB OR SYNC MY IPHONE THROUGH ITUNES VIA USB
    I HAVE AN ISSUE TO SYNC MY IPHONE VIA WIFI (WIRELESSLY), THAT IS MEAN SYNC MY IPHONE WITH ITUNES WITHOUT USING USB CABLE.

  • IPhone 4 suddenly has no wireless connection

    The WiFi on my iPhone 4 is suddenly “Unable to join network.” The router (AirPort Extreme) is working fine; both the iMac and my husband’s iPhone 5 have strong wireless connections. I tried rebooting and re-setting the network settings, to no avail. What happened to my phone's wireless, and how can I get it back?

    Well, I tried again to reset the network settings, via Setings>General>Reset>Network Settings. The phone's wireless still would not connect to the main network, but somehow it accepted the Guest Network. Go figure! Thankfully, it's working now.

  • Nokia 5800 - Loses the wireless connection

    Hello.
    I have a Nokia 5800 cellphone from a week ago.
    I have a problem with the WIFI (Wireless connection).
    If I connect to a WIFI, in approximately 5 minutes the connection hangs, losing the connection. It seems random hangs.
    It happens in all applications, and I have to connect again.
    I tried with several different connections (WIFIs), and the same result.
    Sometimes it stays connected longer, but generally falls.
    Anybody know it can be, and the solution?
    Thank you very much.

    I have had this happen as well sitting right across from my router. Can be working fine and then all of a sudden kicks me out to the home screen. Since there is no connection failure message I have to conclude that it is a random bug, possibly with the built in browser. I have not tested this with Opera Mini yet to see if it is hardware or software related.
    If I have helped you with your problem in some way, please take a little time and hit the kudos button in my post. Without your feedback, I don't know if I am being helpful or should just be put out to pasture.

  • Since installing Airport Express wireless connection to other devices keeps being dropped

    Our home network consists of my MacBook Pro 15", my wife's quite old Compaq notebook, an Apple TV, and recently, an Airport Express.
    The router is one that was provided by our ISP, Alice/O2 in Germany. I think it is made by Siemens but its model name is Alice IAD 4421 WLAN (in case anyone in Germany is reading this.)
    My MacBook connects to the WiFi broadcast perfectly every time, as did my wife's Windows laptop until recently. Between our two machines there was a total of one single occasion where the signal dropped, and a restart of the router got it back up and runnning.
    The Apple TV was set up without any problems at all, the wireless connection dropped out once over the space of 6 weeks.
    About 5 days ago, I bought and installed an Airport Express which has so far served the sole function of providing Airplay to 2.0 speakers in the kitchen, so I just selected 'join network' when setting it up in Airport Utility.
    Since it was installed, video playing over Airplay to the Apple TV keeps stopping, with the message 'Apple TV is not connected to the internet', the AE itself suffers from dropouts in audio, (the LED has always stayed solid green) and my wifes notebook can only join the network after she has restarted it.
    A restart of the router helps for about an hour, but the problems keep recurring.
    Does anyone have any idea of any changes I can make to the AE settings, as it seems to be the cause of the dodgy connections to the other devices?

    Hello mathias1711. Welcome to the Apple Discussions!
    Let's double-check your AirPort Express Base Station's (AX) settings for streaming iTunes ...
    Perform a "factory default" reset of the AX
    o (ref: http://docs.info.apple.com/article.html?artnum=108044)
    To set up AirTunes on the AX, either connect to the AX's wireless network or temporarily connect your computer directly (using an Ethernet cable) to the Ethernet port of the AX, and then, use the AirPort Admin Utility to check these settings:
    AirPort tab
    o Base Station Name: <whatever you wish or use the default>
    o Wireless Mode: Join an Existing Wireless Network (Wireless Client)
    o Wireless Network: <select the existing wireless network>
    Music tab
    o Enable AirTunes on this base station (checked)
    o Enable AirTunes over the Ethernet port (optional)
    o iTunes Speaker Name: <whatever you wish>
    o iTunes Speaker Password (optional)
    In iTunes:
    iTunes > Preferences... > Advanced > General
    o Look for remote speakers connected with AirTunes (checked)

  • 5th Generation Airport Extreme - Wifi Slow, dropping connections

    I just upgraded my 2nd generation Airport Extreme to a refurbished 5th generation I purchased from Apple.com
    I duplicated the configuration of the old one, as I have a static IP address and what not from my ISP. Also, I have a few port mappings for outside access. Everything plugged in via ethernet, seems to be working without issue.
    Everything wireless, which is to say - a Roku, a desktop/all in one, 3 laptops, 4 smartphones, and a tablet are not working as expected. Oddly enough, they are slow to resolve. For example, going to www.yahoo.com took nearly 20 seconds to resolve. At first I thought it was a DNS service issu, and changed to another set of DNS servers (went from Level 3 to another provider, just to test)..... same thing. Also, computers would also go from connected to "limited connectivity".
    Network is a mixed bag Windows 7, 8, and OS X, same with phones, Windows Phone, iOS, and Android, tablet is webOS or something. Everything is at least 802.11 n compatible.
    In my Wireless Settings of Airport Utility I have this configured:
    Radio Mode: Automatic - manual 802.11a/n - 802.11b/g/n
    Radio Channel Selection - 149 5ghz and 1 2.4 ghz
    Security, wpa2
    Wireless Network Options: unchecked is 5ghz network name
    Multicast = low
    Country = USA
    Transmit power = 100%
    WPA group key timeout = 60 seconds
    I unchecked use wide channels, and create a closed network is not checked.
    Now, I have a older airport express (I think it's 3rd gen) that I use in a plug that borders my living room / kitchen to extend the network. Nothing peculiar is configured on that thing other than the default network extension settings.
    At the moment, it is unplugged, as I was using inSSIDer to make sure my network was configured to the right channels compared to what my neighbors were doing. Everyone else is on 6 or 12, and there are no 5ghz channels in range.
    Does anyone know what might be causing the horrific resolution times on my Macbook Pro... it's pretty awful, loading your average websites takes far more time over wifi than over ethernet (also tested this).
    Really, nothing changed except some 'newer' hardware was added, the 5th gen airport. Any help is appreciated!

    Ok i have a relatively new Extreme and here is what i see on 5 GHz vs 2.4 GHz.
    This happens frequently - the 5 GHz wireless connection drops, slows way down, or just does not connect.
    I reassociate to 2.4GHz and viola, works perfectly.  This is with 7.7.2 firmware.

    I just did this and was about to post it when i saw this original post.  This has been a CONSTANT problem with my Airport Extreme since I bought it....   in general 5 GHz coverage pretty much ***** in my house - a two story wood frame house - and its very flaky... very unpredictable. 
    I suspect the hardware myself... and i work in the wifi tech business...
    Message was edited by: Mark Ennamorato1   AND i just was switching back and forth to 5GHz again..im 60 feet away in another room on the same floor, and Airport Utility (yet another piece of junk software but that's another discussion...) cannot even FIND the A.E....until i switch back to 2.4 GHz... clearly this thing is in a bad state right now for some unknown reason
    Message was edited by: Mark Ennamorato1  oops wow...Airport Utility actually saw the AE after about a minute on 5 GHz...  finds it in about 1 second on 2.4 GHz.

    I am trying to log onto my wireless connection but it keeps telling me I'm unable to locate any wireless network.  I know there are several networks nearby. Is this a problem with my phone or my router?

    I found a solution that has worked on both iPhone 4's I have that have had the same issues, and also including not being able to download updates in the App store.
    Go to Settings > WiFi and turn it OFF.
    Next go to General > Cellular > Cellular Data and turn it OFF
    Next go back to Settings > WiFi and turn it ON, (wait a few seconds for it to sync with your network)
    Finally go back to General > Cellular > Cellular Data and turn it ON.
    I had the same issues on both my wife's phone, and my own, and it fixed it immediately without changing any proxy settings or reboots, (which I did try on my phone and did not work, but did not try on my wife's phone)
    Hope this helps!
