Macbook pro wireless signal acting very sporadic

Hi everyone!
My macbook pro recently starting acting strangely, after two years of no problems what so ever.
It seems that i can only get a very strong signal when i am in the same room as the router and even then the signal goes up and down constantly. It's very frustrating, especially when my iphone gets a very strong signal all the time.
I've tried zapping the PRAM and setting the router to g only. Although, I dont think it is the router. The problem occurs no matter where I go. If anyone has any ideas about what may be the cause and how to fix it, I would be greatly appreciative!
Thanks to all,
Rhemy

So is this an authoritative answer? I have seen exactly the same problem. My wife's MacBook Pro keeps losing its connection, but my iMac G4 and my Powerbook G4 work fine. We are all talking to the same Dlink DI-524 WAP, but only her MacBook Pro has this problem.
The workaround I have been using is to renew her dhcp lease every time she loses contact. This works, but it's a PIA as you say.
If I were to want to go back to 10.4.8, how on earth does one do that? Does Apple have any official opinion on this problem, or better yet, a fix?

  • MacBook Pro wireless signal issue

    I've been experiencing this issue for at least a month now and it is driving me up the wall. Occasionally, my wireless signal will drop and I'll either be unable to connect to websites, or when I do it takes a very long time. And the only cure I find for this is to go to the menu bar and 'Turn Airport Off', wait a sec, then 'Turn Airport On'. This is a pain and I'm sick of doing it.
    The drop occurs intermittently, some times once a day, sometimes 10 times in as many minutes. Most of the time I can see the signal indicator in the menu bar drop from 4 bars to 3. Also, it isn't a matter of signal strength as I am sitting 10 feet from the router.
    I know it's not an issue with my ISP (Verizon Fios) or their router, because wired hosts dont have this problem and the wireless Windows hosts in my house dont have the problem.
    I'm wondering if anyone else has experienced this issue, and if there is a fix. Thanks.

  • Macbook Pro Wireless Signal Strength

    I am confused. My wife and I both bought new Macbook Pros last week. She has the stock 15" 2.2ghz and I have the 2.4ghz with 160gb 7200 rpm drive.
    On my machine, the only way I can get 4 bars of signal coverage is to be within 5 feet of our router. On her machine she gets 4 bars all over the house. Same for my ibook g4 800mhz "dinosaur". That one gets the full strength as well.
    Did I get a lemon? It seems to work well even with 3 bars, but I travel for a living and I depend on wireless services in hotels to "live my digital life." Is this going to be a problem? Waiting for a night in a hotel, which should be any day now, but I'm kinda wondering if I should talk to apple about this....
    anyone have a similar experience with only 3 bars? Also, does 3 bars mean anywhere from 75%-100%? Is there a way to find an exact percentage of signal strength? Thanks for any and all replies.

    What is the type of router you use? Check with it's vendor support page, as mine needed an upgrade after 10.4 and the dreaded network upgrade.
    Also, go to a free internet cafe (like Tully's) and see if you can duplicate this. That will narrow it down to your home router or the machine. My Vista machine also had problems with my wireless network until I updated my wireless card software for it. XP would run fine, 5 bars, Vista, 2 bars.
    There have been a lot of odd issues with the updates to all these wireless cards, moving through a variety of new standards including problems with WPA and other security protocols. Given where I live, I simply disabled security on the network, assuming that there are not many people out here wanting to hack my network. In a city or suburb, I'd probably be using security though.

  • Macbook Pro wireless signal going in and out

    I recently got comcast highspeed internet with the wireless network. Everything works fine when I'm using my MBP in the same room as the router. But when I go to my office which is only about 20ft away the signal struggles to stay strong. What's frustrating is that my G4 is in the same room and has no problem picking up and keeping a strong signal.
    On top of that, when I connect my MBP to my 23" cinema display and close the MBP the airport card cuts off completely and can't even connect to, and sometimes doesn't even show the network in the list.
    HELP!!!
    PS: If this question belongs in a different section please feel free to let me know.

    This happened to me when I updated to 10.4.10 but it seems from your profile you are still under 10.4.9.
    Problem solved by reverting to the "IO80211Family.kext" of 10.4.9 in System/Library/Extensions as described in an other discussion on this forum

  • MacBook Pro mid-2012 running very slowly after upgrade to Yosemite

    Problem description:
    MacBook Pro mid-2012 - installed Yosemite, and the system now crawls. Webpages have very delayed responses, can take 30+ seconds to react to typing or selection. I turned off FileVault, that did not appear to help. Emptied the trash, removed some obsolete fonts. Any help for what else to try would be much appreciated.

  • Fed up of Macbook Pro wireless problems

    I'm having lots of trouble with my Macbook Pro wireless and really don't know what to do with it.
    My own router (3COM officeconnect) I cannot connect to at all no matter what I try - but I've given up hope on that anyways.
    My current problem is that at a friends house with a Linksys 11g wifi router (forgot which one) I can connect to the wifi network (WEP128) but I cant browse the net! I can ping IP numbers directly, but I cannot ping names (such as www.google.com). I keep getting 'cannot resolve host'. strangely enough, after I reboot a number of times sometimes I CAN browse the net...
    I'm currently at a hospital which is fully decked out with CISCO wifi access points (unsecured) everywhere, which my 5 year old HP can access no problems within seconds of booting up, my mobile phone can access without any configuration... but my state of the art macbook pro cannot. I have the same problem as the Linksys, I can connect to their network, I can ping IP addresses, but cant browse the web or ping names (and ive been rebooting and trying for about 8 hours now).
    I took the MBP to an apple certified service place a whileback and they concluded the hardware was fine, cos I can connect to apple wifi points (which is all they care about). Ive never had any problems with wifi on windows, linux, PSP, symbian or Windows Mobile... but the MBP seems to be in a league of its own.
    I'm hoping this is a configuration issue, but I dont know what I would need to configure, both the hp and mobile phone can connect without any configuration, so I would have expected the mbp to connect easily too. I havnt changed any settings on it.
    It sounds like a DNS issue so I checked the DNS servers assigned to the mbp, and its the same as the whats on the hp(all assigned with DHCP). Just in case I tried putting in the DNS servers manually but still I get the same thing.
    If anyone has any ideas or suggestions it would be much appreciated!
    (On another note, I just logged in and I was asked to create a new account for these forums! dunno what happened but now Ive started from scratch! i had loads of posts, subscribtions etc.! all gone!)
    MBP C2D 3GB / MP 8core 8GB X1900 / Shuttle SN25P 3800+ 2GB GF7800GTX   Mac OS X (10.4.10)  

    "My current problem is that at a friends house with a Linksys 11g wifi router (forgot which one) I can connect to the wifi network (WEP128) but I cant browse the net!"
    This is the exact same problem I'm having. The ONLY time I was able to connect to the internet w/ my MBP was at a cafe w/ a linksys connection, the first day I had the MBP. But now I can't even connect there. Although internet connect SAYS I'm connected to linksys and shows a strong signal, and my network diagnostics show that I'm connected, I can't browse the internet. I bought this partly to do video editing in Final Cut Pro (why I needed an MBP rather than the less expensive macbook) and partly so that I could work between classes, which is absolutely necessary for me. But I haven't been able to connect on my college campus despite the fact that no one else is having problems w/ their PCs or their macbooks. Everywhere I go with this thing, I'm the only one having problems (and I should mention that I happen to be the only person using an MBP in each place I've tested it...). I'm not sure what to do. I can't configure any routers or anything because I'm connecting in public places (at home I use a highspeed DSL connection w/ a PC), and there are no problems w/ the routers anyways, since everyone w/ older laptops is connecting just fine.
    So far this is what I've done to try to fix it:
    -Went over everything with Apple tech support, who said that all of my configurations were correct and that it was a problem with the 10.4.10 update. So I...
    -Reinstalled my operating system to go back to 10.4.9. Still the same problem. So I...
    -Zapped the PRAM. Nothing.
    -Did the Macbook Pro Update that came out yesterday. Nothing.
    -Installed the latest security update. Nothing.
    I should mention I've only had this laptop for about a week, haven't changed any settings (I'm new to Macs so I would be uncomfortable doing so, anyways), and haven't installed anything except for a trial version of the Mac FTP program Fetch (which was working fine the one time I was able to get connected). I guess I'm going to uninstall that and forfeit the rest of my trial period, but I really doubt that program is the problem.
    Anyways, I'm really frustrated as well. I guess I'm going to try to download the program mentioned in this thread to clear my cache. I'll let you know if it works, by some miracle...

  • I just upgraded my system to Mountain Lion. If I restore my Macbook Pro back to the very beginning state, will the Mountain Lion be removed or not? Thank you

    I just upgraded my system to Mountain Lion. If I restore my Macbook Pro back to the very beginning state, will the Mountain Lion be removed or not? Thank you

    The only problem that I forsee is that some have reported problems getting machine-specific builds of Lion via Internet Recovery. Not sure if it's working yet or not. But you could give it a shot, I suppose. Basically what you want to do is 'prepare your computer for resale' - just like it came out of the box. Kappy, a pretty wonderful and very knowledgeable man, has tip for that which I have copied and will paste below:
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Erase the hard drive:
        1.    Select Disk Utility from the main menu and click on the Continue button.
        2.    After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on the Erase tab in the DU main window.
        3.    Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
        4.    Quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Install button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    Good luck,
    Clinton

  • My keyboard on macbook pro (laptop) is acting weird. One key is not responding at all. Have verified using Keyboard viewer and some other keys are printing the unresponsive character at random.

    my keyboard on macbook pro (laptop) is acting weird. One key is not responding at all. Have verified using Keyboard viewer and some other keys are printing the unresponsive character at random. "z" is the unresponsive character.
    Is it a damaged keyboard ?
    The laptop is just 2 months old, will Apple replace it with a new one if its indeed a damaged keyboard or just repair, I use it for official purposes so being without a laptop is not much of an option.

    No one here works for Apple, so we don't know what Apple might or might not do.  If it's a genuine defect, they will of course repair it under warranty.  It is not their responsibility if it effects your ability to work or not, so that's on you.
    If, however, they determine that the key is problematic as a result of your misuse of the laptop, then everything is on you.  And trust me, if they find a glob of dried up beer or coffee there, they will charge you.
    Your only choice is to take it in for repair.

    Which external hard drive should I use/choose as I am setting up Time Machine on my MacBook Pro 15 for the very first time?

    Any of these SATA HDDs that are at least the same size as your internal HDD (preferably larger capacity).  In addition you will need an enclosure, preferably one with a Firewire as well as a USB connection.

  • HT3500 how can i connect my macbook pro wirelessly to an hp printer with a asus rt 66acr router?

    how can i connect my macbook pro wirelessly to an hp printer with a asus rt 66acr router?

    Firstly, the HP printer must be connected to the ASUS' network. Then, simply connect your MBP to the network and your printer should be addable in Print & Fax in System Preferences.

    In order to resolve the issue if it occurs again, more info would be helpful as to what occurred prior to the "hang." One potential fix would be to try a Safe Boot:
    After the Mac is completely shut down, push the power button and immediately after the startup tone, hold down the Shift key. The Shift key should be held as soon as possible after the startup tone but not before.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    There should be a message that says "SafeBoot." After the Mac is completely booted, try restarting and see if the issue is gone.

  • HT5287 DVD and CD sharing will not let you play or share DVD movies and audio CD's.  Does any one know of a way to get music from a CD on a MacBook Pro wirelessly to an iMac?

    DVD and CD sharing will not let you play or share DVD movies and audio CD's.  Does any one know of a way to get music from a CD on a MacBook Pro wirelessly to an iMac?

    I cannot find the eMac install disk, and I haven't been able to get it to start up from my 10.3 CDRm (holding down option or c), though I read something somewhere about these not being able to start up from system folders earlier than those they shipped with. I've dealt with this sort of thing several times before, and it always seemed to work to simply use target disk mode.
    It definitely won't start up fromt the 10.5 DVD-R, and I'm pretty sure I tried putting the MBP into TM to use its optical drive as well, but it didn't work. But it's worth trying again, and I appreciate your input greatly.

  • I want to connect my ps3 to my macbook pro wirelessly.

    I want to connect my ps3 to my macbook pro wirelessly, my macbook pro is connected to the internet via ethernet.

    OS X offers a feature known as Internet Sharing. With this feature enabled, the Mac Pro would perform as a "software" router. If the Mac Pro has built-in wireless (AirPort), you could then use this feature to share the Mac Pro's wired Internet connection via AirPort to the PS3.

  • Macbook Pro Retina 13" Gets Very Hot

    Hi, I noticed my Macbook Pro Retina 13" gets very hot after 30 minutes of usage, practically "burning" on my thigh (it left burning mark a few times actually, especially in the summer). I usually put a book between the laptop and me to prevent the heat. Is there a better way?

    What are you doing on your MacBook when it gets hot? I have a retina and it gets hot when I play games like Team Fortress 2 or Garry's Mod, watching videos on youtube, and using the iTunes visualizer. What's odd is it doesn't get hot when I watch movies on iTunes. If it's getting hot just sitting around, you may have a problem that needs to be check out as soon as possible. I had a 13" mid 2012 non-retina pro that had three logic boards replaced in less than a year of purchase. Every time the board was failing, it would freeze sometime after it was put to sleep and it would get really hot and the fan would be screaming trying to keep up. Then it would freeze as I'm using it. The screen would flash pixels of all colors in random spots all around the screen. If Apple didn't cover the repairs, I would have paid $530 per repair.

  • Have MacPro wired to Verizon DSL; how do I add MacBook Pro wireless?

    I have a MacPro connected with an Ethernet cable to a Westell WireSpeed modem that is plugged into the wall phone jack served by Verizon DSL. The MacPro does not have an Airport card. My wife wants to connect her MacBook Pro with built-in Airport Extreme 802.11n wirelessly to the internet.
    I've never used a router before. Would an Airport Extreme Base Station let me operate the MacPro wired and the MacBook Pro wireless simultaneously? If not, how can I do it?

    Yes, the AirPort Extreme or any other vendor's wireless router with a built-in Ethernet switch will provide for both wired and wireless clients simultaneously.
