Blackberry 9320 can't connect to the internet through WIFI

Dear all
I have problem connecting my Blackberry 9320 to the internet via the wifi. I have tried all settings but still can't connect. I connect to the WIFI but when I try to connect to the net its says can't connect to the internet if the problems continues contact your internet service provider. I had the Blackberry 8520, I could connect to the net through the WIFI easily but with this I really don't know where the problem could be. I really need your help

If it says "Contact your service provider", then i don't think it's a problem with BB's end. You need to contact your carrier.
God is Great

  • I recently updated my iPod touch to sync through iCloud - now can't connect to the internet through wifi, my macbook air is working as we speak

    I recently updated my iPod touch to sync through iCloud - now can't connect to the internet through wifi, my macbook air is working as we speak. ive tried 'forgetting this network" in settings; tried turning off and on again; and pulling my hair out! The last was equally useless and a little painful!

    Try:
    - Resetting the iPOd. Nothing will be lost
    Reset iPod touch:  Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.

  • My MacBook pro will not connect to the Internet through wifi yet all other devices do

    My MacBook pro will not connect to the Internet through wifi. I have several other wifi enabled devices and they are all connected to the Internet just fine... What could/would cause this?

    Disable your AirPort and enable in a second. Or check, maybe you need to type in correct digits in; Settings/Network/Advanced/Configure...

  • Firefox just started to do this if on one user account someone has firefox running another user account on the same computer can not connect to the internet through firefox while firefox is running in the first user account

    Windows XP/Windows 7
    2 user accounts on the computer. If each acct is logged into the computer and tries to have firefox running only one can connect to the internet at a time. Have Verizon FIOS for ISP and this just started to occur. Firefox version 8 but also happening in firefox 6.0.2. How can we run firefox in two computer accts at the same time? Thank you

    I am having exactly the same problem. This worked on all versions of Firefox up until mid last week. It started failing on Wednesday, coincident with the installation of Firefox 8.0 (see attached gif showing the automatic update on that date).
    To fix the problem, you have to shut down Firefox 8.0 on one account, switch to the other account and then you can run it there.
    If Firefox 8.0 is running on on account, the other account will run Firefox, but when you enter an URL it waits for quite a while then reports "The connection was reset. The connection was reset while the page was loading".
    We also use Thunderbird 8.0 and it does not exhibit this problem, and works at the same time as Firefox 8.0. I suspect they might share some components.
    I'd be happy to supply more details if needed.
    Thanks,
    Ed

  • Can't connect to the internet through router

    I have an HP Pavillian DV6 laptop, DSL connection through ATT, a Linksys wireless N router.  It had been working fine for abourt 7 months, Then all of a sudden I lost my network connection.  I clicked in the right hand corner to connect to the network & it was gone.  I have tried to re-run the software for the router & I get to where it wants to connect to the internet & it won't.  I have tried to log into the router to run the setup on the internet explorer page using 192.168.1.1 I now can find my network, I click connect, it says it is connected, but no internet.  I can connect to the internet if I plug the modem directly into my laptop, but once I connect from the modem to the router, it will not connect to the internet. I have been searching HP, CIsco, & even my maker of my wirelkess card to see if there were any driver updates.  My wireless card says it is up to date.  I tried to rest my BIOS, that didn't help either.  I'm stumped, & I've spent entirely too much time trying to figure this out with no success, PLEASE HELP!!!!! 

    Reset your router to defaults. Here's the procedure.
    Reconfigure the router so it would connect to the internet. Here's the procedure.
    Reconfigure your wireless settings. Here's the procedure. I suggest you set your SSID to something unique. In addition, set your wireless security to WPA or WPA2. Don't use WEP as it is insecure.

  • Can't connect to the internet via WiFi?

    Okay, so recently my service plan has finished, and i was hoping i can access the internet by using my dsl's home. So i always connect my mob to the DSL, but I cannot access anything, and if I try to open something it would spend from my credits. Is there a way to connect to internet without spending my credits?

    Yes, you will need to set your Options > Advanced > Browser > to Hotspot, and then you will be able to use the HotSpot browser for internet surfing and usage only. You will not have access to all of the BlackBerry applications like Facebook for BlackBerry, RIM's push email, Messenger, etc.
    Some third party applications like Pandora radio will work on WiFi connection only.

  • Updated my ipad yesterday and today can't connect to the internet by wifi or cellular.  Have tried on 2 different wifi routers, one by Verizon and another by Comcast.  updated 2 iphone 5S and ipad mini today and all 3 work fine.  Any suggestions?

    Updated ipad yesterday to 7.0.6 and now can't connect to internet.  Tried cellular, Verizon and Comcast.  Updated 2 iphone 5S and ipad mini today and all work fine.  Any suggestions?

    Has the unit EVER been jailbroke?
    If "No," first try a system reset.  It cures many ills and it's quick, easy and harmless...
    Hold down the on/off switch and the Home button simultaneously until you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  It could take well over an hour!  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow the on-screen directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
    At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod.  As before, say "yes."  Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time.  If that happens, only the apps that are part of the IOS will appear on your device.  Corrective action is simple -  choose manual "Sync" from the bottom right of iTunes.
    If you're unable to do the Restore, go into Recovery Mode per the instructions here.  You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without being charged again.  Also, if you have IOS-7, read this.

    No data is lost due to a reset.

  • After update I can't connect to the internet in no way, shape or form

    I rarely update because: 1) something always breaks when you update (like now) and 2) I don't like to deal with new crap like GNOME 3. Anyway:
    I bought a new router (TL-WR1043N) and configured it with an old Ubuntu because connecting to 192.168.1.1 didn't work on any of my Arch Linux installations. Now... here's where it all starts... I can't use the 'n' wireless on my laptop since I have to install something to use WPA, and to install that I need to update, but I don't want to deal with GNOME 3 and Firefox >3. But I gave up eventually gave up and connected my laptop to the router by Ethernet cable. Setting that up was very easy: 'ifconfig eth0 up; dhcpcd'. Voila! I updated my whole system and restarted. To see how badly I damaged my system I opened Nautilus (I use Openbox with some GNOME programs): shock and dismay, the fonts are visible from the moon. I guess I'll have to quit using GNOME programs completely now but I expected that. I used to use KDE back in the day and when KDE4 came forth from that unholy pit, I immediately abandoned it for GNOME. This time we had more time to prepare, everybody knew what GNOME 3 was going to be. I started using Openbox quite a long time ago.
    Anyway: Now to fix my wireless right? WRONG! I can't connect to the internet on cable to get the packages for wireless. I installed Windows 7 64 on the same laptop and it connects to the cable. Ubuntu 9.10 Live also connects, but due to the changes of rc.conf and network stuff I can't connect at all with Arch Linux.
    So I decided to abandon it completely and reinstall from scratch. But the Live CD also doesn't work. With all the ways I've tried it all comes down to this:
    dhcpcd always times out waiting for a carrier and 'ip addr' shows 'eth0: <NO-CARRIER, ....' if the interface is up. I'm not sure what information I should give you, but I can't paste any here since I can't connect to the damn internet on that laptop.
    About the router: the cable is plugged on port 1 and the LED for it flashes if I reboot the computer. In Windows it stops flashing while it connects and flashes again when connected. I removed 'network' from DAEMONS and it flashes till I start it with '/etc/rc.d/network start'. This hangs for a while and returns '[DONE]' even though it doesn't work and the LED never flashes again on the router.
    In rc.conf I have exactly what the example says for DHCP. In any case, it doesn't work with the Live CD either.
    EDIT 1: From lscpi: painstakingly typed:
    06:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)
    07:00.0 Ethernet controller: Realtek Semiconducctor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01)
    EDIT 2: Just to be clear: I can use the wireless on the laptop on the Live CD, but I want to use the cable because of the greater speed (94Mbit/s on cable 60 something on wireless n, 20 something on g) and because I rarely move the laptop.
    EDIT 3: lspci -v shows "Kernel driver in use: r8169   /   Kernel modules: r8169", so the driver is loaded.
    EDIT 4: So if I boot from the CD. ip addr shows:
    eth: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
        link/ether 00:1d:92:...etc... brd ff:ff:ff:ff:ff:ff
    And  the LED flashes. When I type: "ifconfig eth0 up" it stops, never to light up again and ip addr shows: "eth: <nO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000
    Last edited by imtired (2011-09-08 12:36:51)

    When you're in Arch, use output redirection
    lspci >lspci.out
    then boot into Ubuntu or something where you can access the files and the BBS,  Of course, don't forget to use a new file for each command output.
    The new network config in rc.conf is not that complicated (wired anyway; never used wireless).  OTOH I've had issues on two machines where I have to restart the network daemon (rc.d restart network) or rerun netcfg (netcfg eth0) after boot to get connectivity. And I still haven't come to grips with the ip command.

  • Safari 5.1.1 can't connect to the internet.  Every other browser can.

    I've tried resetting Safari, reinstalling Safari, and resetting my router to factory settings.  Safari still can't connect to the internet, but everything else on my Mac (Snow Leopard 10.6.8) can. 
    I recently tried setting up Open DNS just because I've had problems with Comcast lately.  But I've since returned DNS to be detected automatically.
    Thoughts?

  • Can't Connect To The Internet Or Router

    I have had my router set up for about three years.  It's always worked perfectly fine until the other day. I think that the router just died, but I'm not sure and I want to try and fix this one before I just go out and buy a new one.
    Basic Background Information:
    Model No:WRT54GC
    -The router is and always has been hooked up to a surge protector and there haven't been any other recent surges in my home.
    -When the wireless router is connected to the computer (using a functioning Ethernet cable ) I cannot connect to the internet or the router.  (I can't even put the IP into a browser and bring it up.  I also tried the factory setting IP, just incase it actually did reset, and that doesn't work either.)
    -When the router is plugged in I can't see it from any other wireless computer.  (I also checked for any new signals and did not see any after I reset the router.)
    -LEDs look like:
          *Power = solid green
          *Internet = solid green 
          *wireless = hard to tell - doesn't look like it's on at all
          *all other Ethernet pluggins = solid green
    What I've Tried So Far:
    -I couldn't connect to the internet so I plugged the modem directly into my computer.  -->  The internet works.
    -I tried unplugging the router, waiting, and then plugging it back in.  -->  I couldn't connect to the internet or the router.
    -I tried the reset button.  -->  I couldn't connect to the internet or the router.
    -I tried leaving the router unplugged all night and then plugging it in and starting the process all over again.  -->  I couldn't connect to the internet or the router.
    -I also tried downloading new firmware, but since I can't connect to the router through any of my browsers I am unsure how else to update the firmware. 
    Thanks in advance for any help!

    Try upgrading your Router's firmware and then you can reconfigure your Router from the scratch...
    As you are not able to go online through router...you have to download the formware by connecting computer to the modem..
    Go to website linksysbycisco.com/downloads.........insert model no of your router in serach tab......select proper version of your router........download the firmware file......save that file on desktop
    Now reconnect the Modem to Router on Internet Port and from Computer to Router on Ethernet Port 1and now Press and hold the reset button for 60 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...
    Now you can upgrade the firmware using TFTP utility...Download tftp utility.
    Follow these steps to upgrade the firmware on the device : -
    Double click the TFTP.exe file and click run.
    For Server- Enter the IP Address of the router that you assigned.  By default, the router is 192.168.1.1...
    For Password- Enter the password you assigned the router. By default, the router’s password is “admin”.
    For File- Click the triple “…” button and browse for the .bin firmware file...
    Click Upgrade button to start upgrading.  A progress bar should show up to show the progress.
    Once the Upgrade is done press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

  • Can't connect to the internet

    Ok. so i did a search and didn't come across any other problems like the one I'm having.
    Let me start off by stating that my laptop is an ibook g4 bought feb, '06 (yes the apple care just ran out).
    I'm having a problem connecting to the internet on my ibook, running through a d-link wireless router. I'm using my imac to connect to the internet currently (which works fine by the way). It also is connected through the wireless router.
    My ibook has a strange ailment. I open up Safari and all I get is a blank screen, the page is trying to load but the status bar is going no where and does the same in Firefox. So first, I opened Network diagnostics, but the computer freezes and I have to do a hard shutdown. (holding the power button). Next, I tried Disk utility. Verified Permissions, Repaired Permissions, everything is fine. I tried to Verify Disk, and again the computer freezes, will not let me force quit and I am forced to do another hard shutdown. I do the thing where you hold down some key while you're starting up to get into the disk utility so I can repair the disk. This returns clean as well. I downloaded techtool off of my Applecare disk. Did the tests, everything passes. So what's the deal?? I've tried to reset the pram. I even did the Apple Hardware test, everything passed.
    I thought it could be my Airport card? It recognizes that there is an internet connection in the top right corner, I even have great signal strength (mostly because I've tried this sitting right next to the router). But still, I can't connect to the internet. Any one have any ideas? I don't know what else to try! Please help!

    so i can't believe i didn't try to connect it directly to the router with the ethernet cord. This actually worked. But it still didn't solve my wireless problem. I'm not willing to let my laptop become a desktop. I'm already wired to a plug b/c the battery is slowly dying and has a life of about 5 minutes. I'm not willing to give up my wireless internet too.
    I guess now it's got to be the airport card? how do I confirm this? and if it is how much would a new one cost and can I install it myself??

  • Can connect to my house network, but can't connect to the Internet (other computers can)

    Hello,
    I'm experiencing a strange problem. Since I started my Mac Pro (cold start) some hours ago, I've lost the hability to connect to the Internet (Safari and Mail say I'm not connected). However, I can connect to 192.168.2.1 (my router) and see its webpage (it says it's connected to the Internet). If I use another computer on the same network, it can also connect to the Internet.
    Weirder, if I go back to my Mac Pro with "no internet" and launch Parallels Desktop, then I can use WinXP to browse the Internet; I'm writing this post on my WinXP virtual machine.
    This leads me to think there's a problem with how my Mac OS handles the networking. I have checked the Console, but the only related string I found is this:
    16.04.13 22:03:25
    kernel
    SIOCPROTOATTACH_IN6: en2 error=17
    As expected, Google doesn't reveal anything about that (and I'm connected with the first ethernet port). I've tried to restart my Mac, but the problem persists (exact same symptoms).
    Could it be a DNS cache issue?
    I don't see, other than a DNS problem, why I can't connect to the Internet with my Mac OS while I can on my virtual machines. If it was a driver problem, I wouldn't be able to connect to my router. If it's a DNS issue, where are the DNS caches located in order to clear them (I'd trash the folder)?
    I could also reinstall the OS (waste of time, btw), but I'd really like to understand the problem, not just clear it and forget about it.
    Or better than guesses, anyone already experienced this?
    Any help welcome.

    If it's a DNS issue, where are the DNS caches located in order to clear them (I'd trash the folder)
    No DNS caches, it looks up the alphabetic and then uses the numberic from then on.
    http://17.149.160.49
    is Apple, Inc main US web site. It that works, and the alphabetic does not, you have a DNS probelm.

  • Extreme (b/g/n) can't connect to the internet

    my iMac has no problem seeing my airport extreme (b/g/n), but I can't connect to the internet.
    I have tried soft / hard reset & factory reset as well, none of them worked. The extreme just keep flashing its amber light.
    On my iMac, I have full signal bars, so recognizing the extreme is not a problem. The only thing I find strange is that the IP address (the one assigned by my ISP) is 0.0.0.1.
    I tried connecting through an Ethernet cable and it didn't have any problem, so it's not my ISP. The only thing I can thing of is that the extreme somehow is having trouble recognizing that assigned IP and that's why I can't get connect to the internet.
    Anyone suggestion? Is my extreme broken? If so, can it be fixed? Please help.

    Problem solved!
    Every time, I feel so stupid once I find out the answer to my problem.
    Here it is from another post by 'dwbird':
    "Solution: I found that the service name (optional on the setup) may be optional but if your service doesn't require it and you put a service name in the block it prevents the system from working, hence cannot find the PPoE Server and also cannot get an IP address assigned. Guess the moral of the story is that if it is not absolutely required don't fill in any "optional" blocks"
    I deleted the name of my ISP and everything works just fine, the stupidest thing is that this is not the first time...
    maybe Apple should consider putting a reminder/warning underneath this OPTIONAL service name field.

  • Can't connect to the internet with Airport OR ethernet cable

    I know many other people are having problems with airport not being able to connect to the internet. I've never had any problems with my mac before, but 2 days ago, it started to act really funny. When i turned it on, my time and date were changed to Jan. 1, 2000, and I kept on getting notifications about configd and mdnsresponder wanting to connect to the internet. I did a little research and fixed that problem. Then, a few days ago, my internet was dropped from my computer completely, and I've never been able to connect via airport since.
    The main problem is that even when I plug the ethernet cable into my mac, I can't connect to the internet either. It worked a few days ago, but now my computer can't even connect. It registers that the cable is in the computer, but thats' about it. The Network Diagnostics assistant tells me to restart themodem, and that hasn't been helping at all. Any helpwould be appreciated.

    First Reset your Pram to see if resets you clock (the different Date caused the problems. Plus open System Preferences->Date & Time pane. In there make sure you set the current date/time and se if you can have the Mac automatically update the time from a Time Server.
