    I have an early 2008 MacBook Pro and running Mavericks. It seems to operate well, except for two weird problems. I am in Ireland, so I do not have an Apple store to bring this to. I suppose I could go to London, but I'd like to have an idea what's going on first (if possible!)

    Wifi

    Sometimes the Wifi will drop. The icon will show full bars, but when you select it, you won't see a single network listed, even though it is on. If you go to Network Preferences, it will show the wifi as on. If you turn the wifi off, you won't be able to turn it on again, as clicking turn on will do nothing.

    The only solution I have found is to reboot the machine, which is less than desirable.


    Lock Ups

    These are not spinning ball locks up. These are absolute freezes. No keys are responsive. Hitting the capslock key yields no light. Everything just is frozen. If I was playing a game, the music will sort of carry on in a very distorted and looped/stuttering fashion.

    I've noticed this type of lockup is most likely to occur if I had the laptop on my lap and then, in the process of picking it off my lap to the table, it would lock up then. This is how it locks up 3/4 the time; however, not always. It can be on my lap and just freeze. I've even had it freeze while on the table a couple times, so perhaps the movement of the laptop is just a coincidence, though I really think it may be related.

    The lockup does not seem to be programme related, per say, as it can happen when I'm playing a game, when I'm in word, when I'm in Chrome, etc. I used to think it had to do with Safari, as one day I was running Safari and it kept locking up over and over, seemingly every 15 minutes or so, so I switched to Chrome and it had ceased for a few hours...but it still locks up, so I doubt that was it.

    What can I do to diagnose this/fix this? It's driving me a bit nuts. I haven't lost any important information, yet, but I figure that's only a matter of time.

    I have smcFanControl and the fan is running most the time. My temperature runs about 98 to 150, generally around 120 (like right now). I also have Trim Enabler. I have a few games, Word, Excel, Skype and thats about it. Nothing else is installed and I installed Mavericks about 5 weeks ago, so it's a clean install.

    Same Issues

    I've been getting both of these issues on my 2009 MBP 15. I updated to mavericks too and sure enough these issues are a bummer.

    I also run smcFanControl, my temps are on par with yours and the symptoms the same.

    Any clue what this could be? I've been searching and wrecking my head. I found a couple others who say they have this issue, but no solution below their complaint.

    No issue...

    The issue of WIFI dropping only happened for the first time last week, it occurred twice. Tried to delete and read the wifi to fix the problem.

    It required a restart and then everything back to normal. Nothing occurred since. Not sure if deleting and adding wifi again in network helped or not. :rolleyes:

    Repair disk permissions using recovery hd disk utility and reset the smc/pram and see how you all get on afterwards..

    Just did that.

    Too early to tell re the lockups, but the wifi matter is still an issue.

    In typing this brief message, it's done it to me three times. It's getting a bit crazy now...

    Download a wifi scanner app, one of your neighbours may have upgraded their router and your signal is getting bled over. May have to change your wireless channel on your router to cure it.

    Nothing new I'm afraid. Was experiencing that at work as well.

    I'll monitor that; however, as maybe that would have some issue. I noticed the wifi on my mobile doesn't seem to drop. A reboot on my computer tends to solve the issue.

    Reset the pram and smc, could be the card but there's plenty of them on eBay.

    Did that, going to see how it impacts things. No lockups yet, but they aren't as frequent as the wifi dropping. Hopefully this is the last of it!

    Reset the pram and smc.

    Unfortunately suffered a freeze just there. My wifi drops about every few minutes, quite frustrating as none of my other devices are having an issue so I don't think it's the router.

    The card is your next port of call, could check a connector hasn't popped off first but doesn't sound like it.

    Thank you and thank you for the links. I will purchase and revert.

    Are the lockups just a Mavericks issue?

    Not likely the card

    When the problem occurred on my Penryn Macbook Pro, I had not long before installed a wifi "n" card. The problem is definitely most likely something regarding Mavericks.

    Of the two occurrences, I have not had one since going into network settings and deleting wifi. Then I created a new one.

    So far so good. Not sure if that's the answer but of the two occurrences seen, it was not right away after updating to Mavericks and then nothing since. YMMV.

    (AFTER I deleted and created a new wifi network, I rebooted. Haven't seen the problem since.)
    :rolleyes:

    Sure it's worth a try! I'll give it a go right now!

    I've tried a lot of things to sort my issues. Resetting SMC AND PRAM as some here have suggested made no difference to the pickups and networking issues. Recreating the WiFi network and recreating it also solved nothing.

    Hopefully apple can acknowledge and fix these issues soon. I would love to have a computer I can use again!

    For what it is worth, and just as a matter of update for others that may have the issue, I simply replaced my Airport Extreme Card and I've had no further issues.

    In fact, replacing the Card also seemed to solve my lockup issues with Mavericks.
