Xp networking problems on mbp c2d

i don't know if this problem should be addressed under the mbp forum or boot camp forum so i'll post in both to get the most input.
i'm having a problem connecting to my home wireless network under bootcamp. i installed xp sp2 as well as the driver cd. when i try to connect to my router it takes a long time detecting the network type. then it pops up a window that says "windows is unable to connect to the selected network. the network may no longer be in range. please refresh the list of available networks, and try again." when i connect to another network in range (that has 0 bars) it quickly detects the network type and gives a window where i can enter the wpa password (which i don't have).
the mbp connects fine under os x. my mac mini along w/ a few windows computers in the house have no problems either.
our router is a 2wire that has wep encryption. the ssid is broadcast and found by windows.
any help would be great. this is driving me nuts!!!

That behavior is normal. Intel's chips use a technology called (I believe) "SpeedStep", which dynamically adjusts the processor speed as is needed. This improves battery life and has no impact on performance.
With respect to quitting the battery, I assume you mean to remove it... This will, in fact, freeze the processors at a max of 1GHz, which is a safety feature.
A quick review of these forums would have revealed that, btw.
Thanks for trolling, though!

FWIW...Solved my Airport reception problem on MBP C2D

After 2 hours with AppleCare it turns out I had to many computers on my airport network (7) which slowed down my benchmark internet times on my MBP C2D at speakeasy. It seems an old G3 iMac may be the main culprit. When I turn off its airport my MBP speed goes up 3-4X.

Nikolaus... I might agree with that except the MBP is the only machine affected. My G4, 1yr old ibook, 2 yr old iMac, and another older G4 are not having any problems. When I turn off the G3 only the MBP C2D improves alot.

MBP C2D + Airport Express + WPA frequently loses connection. but WEP OK

many people seem to have wireless connectivity problems with their MBP
-- here is the problem I see with my 2wk old MBP and my wireless setup at home (Airport Express) and at work (Linksys, model# unknown):
1) MBP C2D + Linksys + WEP = no problems
2) MBP C2D + Airport Express + WEP = no problems
3) MBP C2D + Airport Express + WPA = frequent dropped connection, and poor range
for reference, my previous laptop:
4) Pismo + Airport Express + WEP = no problems
5) Pismo + Linksys + WEP = no problems
with WPA (whether WPA or WPA2) and the MBP, I turn on Airport, signal looks strong, but then suddenly disappears. I have to toggle Airport off and on and then (sometimes) I'll successfully re-establish connection - only to possibly lose it again at some random point in time. Or it may work fine for an hour or more - it's hit or miss. no such problem or inconsistency with WEP enabled instead.
both laptops are running OS X 10.4.8. Of course only 802.11b on the Pismo, but results don't change on the MBP whether b, mixed b/g or only g.
The Airport Express is set up as a closed network, it's running firmware v6.3 (though I also reinstalled v6.1 but no change). I've tried many of the various other ideas for fixes - deleted Airport related keychains, etc played with various other Airport config settings - but all evidence points only to WPA as being the differentiating cause.
does this match anyone else's experience?
and more importantly, is there some fix?
thanks in advance for your feedback or suggestions

Hi!
Used to have same problems. But not anymore.
Here's what I did. I have a DLINK 624 router. not the same model but this could help you, I guess
1) Disable Super G mode into router.
2) Choose a 62 character key with a $ in front of it. (go https://www.grc.com/passwords.htm) and use wpa2.
3) Uncheck the Robutesse Interference (sorry, i am french) in the airport menu.
4) Change the advanced performance settings from auto to 11 (Tx rate) into router.
5) Whent into keychains and only kept the one for the active wi-fi. Since I tried almost verything, there where a lot!
Since I did that, no more lost connection for a day now!
Now I am not saying that this is the ultimate fix....but It worked for me.
BTW, did not do the SMC and EFI upgrade, still a little scared after what I read in the forums...I bought my mac book pro last week...how come it did not came with all the upgrade done??!! bizarre.
Good luck!

MBP C2D unable to boot on external OSX 10.4.8

I have a Mac mini CD and a external HDD, both are installed with OSX 10.4.8. My Mac mini can boot on both OSX. However the MBP C2D is unable to boot on both (mac mini CD in target disk mode, and ext. HDD), it can only boot on the built-in OSX. When I tried to boot that two OSX, first it loads for a while and then freeze at a white screen. Sometimes the white screen may even blink vigorously.
I even had made a disk image of the OSX on the ext. HDD and restored it on my MBP C2D's internal HDD. The same freeze still happened.
Now it seems that the MBP C2D is not compatible for OSX other than its origanal one.
Can anyone confirm the existence of the problem?

It is really bad. Does the Apple support line help? The support line in my region is not that "pro".
For the issue, I had never experience something like that on a Mac, neither MBP CD nor Mac mini CD, they can boot from each other's OSX or OSX on ext. HDDs.
I am really surprised by this problem on MBP C2D. I think it should be software issue and every one using MBP C2D should have the issue, right?

Issues with MBP C2D and networks with any PCs attached...

So for a long time any time I go to anyone's home with a wireless network, I will jump on and the network will stop working for anyone but me. This happened recently when my girlfriend updated from a netgear that broke to a Linksys wrt54gs. Any time I connect my MBP C2D to it wirelessly I know out the rest of the house, 2 desktop PCs. I also have this problem at my store where it affects the people working around me, so that they cannot connect to the net, which is a BIG hinderance to them, obviously. I had this problem with my wrt54g and changed the firmware to one noted somewhere else (different forum) and it works fine, PS3, and everything connected works perfectly. I am almost to the point of buying a PC so I stop knocking out peoples networks, any thoughts on this, I don't want to have to go back to a PC
Oh and I am using a WEP 128bit hex and no other security on both networks.

I had similar problems with a WRT54G Linksys Router, and after a bunch of searching, I found that there is a problem with the latest firmware on the router. I downgraded the firmware as the post recommended (Linksys Forum) and now all my macs can connect.
Here's a link to the post I found on the Linksys site that solved my problems:

MBP C2D - no wireless networks show up: possible soultion

If you can't see any wireless networks, one possible solution is to change the channel of the network.
I've got a quite old Netgear MR314 wireless (802.11b) router. Yesterday I got my Macbook Pro C2D and tried to get connected to my wireless home network. Airport was turned on, but no wireless networks showed up in the list. My Ibook could access my network just fine. I tried to disable all wireless security such as WEP and access control based on the MAC address of the Airport card, but it didn't help. Sometimes I even saw some neighbor's network, but not my own.
Today I logged in to the setup page of the Netgear router and played around with channel setting. By default it was set to 1. Channel 2 didn't work, but when I tried channel 6 or 11 (didn't try all of them), my network showed up in the list and I now get full reception!
Hope this helps someone.
MBP C2D 2,33 / 2 GB Mac OS X (10.4.8)

I had the same problem, turned out my airport card inside the macbook was fried. Apple replaced it and while they were doing it they fried my MB and RAM. So after 2 days I have pretty much a new computer. Buy the extended warranty.

MBP C2D - Problems burning Double Layer Discs

I encounter massive problems when trying to burn DVD+R DL Discs. The MBP C2Ds internal drive is supposed to burn DL media but the only way to burn them is under win xp using my external philips ED16DVDS usb2 burner. Nero produces coasters using the internal matshita burner.
Under Mac OS Toast as well as Mac OS X give me error messages before starting to burn.
The Media I use is called intenso DVD+R double layer. Intenso media has worked exceptionally well for my needs over the last years. This is no cheap stuff.
I am thankful for any suggestions.

Can you tell us exactly what the error message says under Toast?

Problem: DVD-RAM can no longer be read on MBP C2D

The "MATSHITA DVD-R UJ-857D" in my MacBook Pro C2D is said to have read (but not write) support for DVD-RAM media.
During the first few weeks of its lifetime, reading DVD-RAMs definitely worked. But now, no more, no matter what brand of media I try.
All other types of optical media continue to work as advertised (read and write).
I wonder whether this is a physical defect (but then why doesn't it affect other types of media?) or an issue caused by recent sopftware updates (but when I boot from an external DVD-drive using the very original MacOS DVD with no updates at all, why do I still not get read support on the internal drive?).
AFAIK there has not been any recent firmware update for this model. So what can be the reason? Should I let Apple swap the drive? Has anyone else observed the same issue?

Hey Grant,
thought you'd like to know my "cleaning the lens with a cloth" worked fine - uh... but for about three days only, then back to the same old, same old.
I'd originally slid a business card covered with a lens cleaning cloth (from my camera bag) to clean the lens, and although the cloth emerged mostly pristine, I figured it must've done the trick as the drive started working again.
So this time, I decided to go in deeper. I actually took the whole drive apart - case off, drive out, drive dismantled - and I had a long look around to see if any parts looked dirty or damaged...
I found just one thing - the small silver rod on which the read/write head travels (the servomechanism that moves up and down the disc radius as it reads/writes) had some 'oily gunk' at the point where the travelling-head's 'sleeve' met it - when I tried to move the head manually up and down the rod, it sort of staggered along. So I cleaned off the gunk with a cotton bud and then slid the drive-head up and down a few times 'till it seemed to run freely.
Put everything back - and fired up my Mac Pro. And the drive has been 100% fine since then - two whole weeks!
Maybe this time I've cracked it? (for my drive at least)

PB AL 15 to MBP C2D not going well

Tried using Migration Assistant but old PB G4 Al 15" 1.33Ghz always froze as Target Disk on any transfer over 5GB (all that mattered). So moved stuff manually, so no big wonder I'm hosed now.
Please spare me the "wipe it and start over" stuff, installing all the apps & pwd's from scratch will be last resort only, and I manage >60 G4 & G5 Macs at work that will soon migrate to Intel so I need to know how to fix things.
So new MBP 15.4" 2.33Ghz is fine except for:
1. MBP goes online fine at work (web, POP mail, whatever) but typing 1 character into any text field like Google or banks or anything freezes Safari instantly with BBOD. Firefox is fine. Unable to re-install any Java software update or 10.4.8 combo update
2. At home old PB & MBP will connect to Belkin FD7230-4 wire & 802.11g gateway router fine (wireless or wired), can ARD & fileshare fine between them, Network pref's show "connected to network 'xyzap'. ..connected to Internet via Airport (or Ethernet, or both)" but the new MBP can only get RSS feeds (with Safari but NOTHING with Firefox, web sites get "ur not connected 2 internet" [Safari] and "Server not found" [Firefox] nor POP mail for that matter, haven't tried FTP yet..)
x. Why does Migration Assistant fail with target locking up? Tried DU & DW repairs, no luck. On manual moves there were a few files that would kill transfers with "can't read or write" type errors, moving them separately by themselves or deleting got past that.
*** does this tell us? Need some help here.
Thx, dh

Not much attitude about m&a (migration assistant?), but about these forums, I never get any help here.
On about the 5th wipe and install try used ma after install instead of during (not the 1st time trying that way) and it left a log file on desktop (never did b4) which pointed to the mail.app files that were the culprits, deleted them, wiped & installed again and success moving 1 home directory.
That said it seems clear from posts elsewhere that there are issues with "can't read or write" issues. The G4 PB had no problem with the files in question.
And as to internet connections, also obvious from posts elswhere that there r issues with MBP C2D's and wireless gateway routers (NetGear, Linksys, D-link & Belkin (I have Belkin F5D7230-4US8.01.07, what a POS, worked with a couple all day at work trying to set up WDS / bridging, when their "tech support" hung up on me in 1st 5 seconds with 2nd level guy I threw 'em back to wally world). Dug a bit deeper tonight, plugged the MBP straight into cox cable modem again, no luck again UNTIL reboot cable modem then joy.
So reran AirPortUpdate2006002.dmg but no joy. kaka. So anyway gonna mark this 1 done and post over at "Getting Online & Networking" to see if the help there is any better.
peace, -d

MBP C2D internet sharing over Airport

I have DSL connected to my MBP C2D over ethernet and want share this connection over the MBP Airport so other computers can wirelessly access the internet. While other computers can see and connect to the shared Airport connection on the MBP, however there is no internet available. I suspect this is because the MBP C2D is using 802.11N frequency and my other computers are G. How can I force the MBP to transmit in G?
Thanks

Whatever the problem is, it is certainly not related to the G or N standard.
Do you have "Personal Web Sharing" enabled under System Preferences-Sharing-Services? If not - try it.
Under System Preferences - Sharing - Internet review the "Airport Options...", some network names (containing special characters) and encryption settings (40-bit WEP with 5 char password or 128-bit WEP with 13 char password are normally most compatible) can cause problems. On some Windows systems you will need to set the Gateway and DNS IP addresses for the connection manually to point to the shared computer's IP address for Internet functionality to work flawlessly).
HTH,

Time Machine couldn't complete the backup due to a network problem

Firstly apologies for the long post, I've been bottling these problems up and could now use some expert advice.
I have a MacPro (10.6.3) with four internal drives (320GB system/apps. + 3x 750GB data, images etc) and a MacBook Pro (10.6.6) with a 320GB internal. With so much accumulated data (Mac user since SE FDHD) I wanted a reliable means to backup all my projects, books, papers, research, images etc. I had several bad experiences using Iomega drives (Ultramax and Storcentre) which were not very Mac compatible and shifted over to a 10TB LaCie 5Big Network 2 which is promoted as Time Machine compatible. Set up Time Machine (with a few hiccups) in Sept 2010 and it ran perfectly, backing up both main computers until March 2011. I have now experienced a string of problems backing up the MacPro, some of which have been resolved speaking to people, some by checking forums and some by using my own noddle to figure it out. The latest error message I am getting is "Time Machine couldn't complete the backup due to a network problem. Make sure your computer and the backup disc are on the same network, and that the backup disc is turned on. Then try again to back up."
The circumstances of this are as follows: TM seems to be trying to completely back up everything already backed up from previous months so I am using the "exclude" option to do this in manageable chunks (5.54TB of 7.99TB is available so there is a lot of stuff on there, hence my reticence to erase and start again). I started a backup last night which said it was 242GB and when I came back hours later (I estimate 30GB and hour or 500MB a minute) it has failed with the error message above. I asked it to back up again and it said it now had 191GB to backup, at the next failure it was 142GB, dropping by approx 50GB a time (if there a maximum it can manage in one go?), the next time it was starting again with 242GB.
I checked the disc it was backing up to, discovered it was now selecting Public-1, re-selected Public which houses the macpro.sparsebundle, dropped the backup size (Options) to 73GB and set it off again and it is backing up as I write. I am hoping it will complete and permit another chunk to be backup but the fact it looses network connection (seemingly) or has a maximum backup in one go, is annoying because it means you cannot leave it overnight and trust it to do the backups.
The other problem seems to be a shut down by LaCie 5Big because several times (and once this morning) I have had this message "The file server "LaCie 5Big" has closed down, followed by a complete Lacie shut down and auto-reboot with all lights and whistles. Lacie think this could be a power supply problem and say they are sending me another power brick. They also say they do not support Time Machine (they should check their own literature) and suggest I use LaCie 5Big for 'drag and drop' backup. If I wanted to do that I could pick up a cheap and nasty HD from PCWorld, not this high end 10TB drive which cost over £1,000 !
For a while y'day I could not even find the Lacie on the network but after changing the ethernet cable from Lacie to router (Linksys) it miraculously re-appeared so that problem may have been the original Lacie blue ethernet cable had developed a fault. Checking cables is an oft-overlooked option.
A catalogue of errors, some solved, others still all pervading, so any words from the wise would be gratefully accepted.

I verified the macpro.sparsebundle and Time Machine backups in Disk Utility and it said both appeared to be Okay in green type. So that did not solve the issue. I did a Disk Utility repair a day or so again (despite Verify saying everything was fine) and said there was nothing to repair. I suspect two problems, the power brick may be faulty producing intermittent power and maybe causing the drive to close down (hopefully Lacie will send me a replacement to try) and second, I am thinking the network connection is getting dropped causing crashed backups without the Lacie shutdown/reboot sequence. The 73GB back up failed, I started it again at 54GB and it failed again, just started it again at 45GB - this is no way to progress!
Perhaps the relatively new (last year) Linksys router is the problem, I find my MBP says AirPort is active but it fails to appear in Go>Server unless I switch it off and on again and perhaps a similar problem drops the connnection to the Lacie.

Temperature-related startup failure in MBP C2D

My MBP C2D fails at startup when rebooting after normal use (means web surfing and playing music with iTunes) and temperatures in my MBP's CPU cores have been ~50C or more by Temperature Monitor.
At startup DVD-drive makes it's normal eject sound, but then nothing, screen stays black. There is no startup sound or gray screen. I need to shutdown computer, let it cool down and after that it will start again.
Hardware test doesn't find anything and reseting PMU, PRAM or SMC doesn't help.
Problem seems to be temperature-related. Solutions?
Macbook Pro Mac OS X (10.4.8)

Sorry for posting a not-so-helpful reply, but I think perhaps there is something wrong with the temperature sensor(s). The processor should shutdown only when the upper temperature threshold is exceeded. I suppose the hardware test cannot be run when the machine is still "hot"? I would call AppleCare...

Unprompted user switching MBP C2D 2.33 10.5.8

My MBP C2D 2.33 running 10.5.8 has recently developed the following problem: The desktop suddenly "swivels" to the Login Window without having been prompted to do so. It does not log me out, it just switches to the Login Window. When I log back in I can see all of the windows still open with the work in progress, but the computer switches back to the Login Window within a second or two.
Restarting means losing the unsaved work in progress, but allows me to log back in and continue working. The problem has occurred 3 times over the past 3 days, twice while doing nothing more complicated than composing a message in Mail.
This problem is a bit annoying while I'm working at home, but my work involves a lot of presentations for groups from 12-200 people and I can't afford to have this happen under those circumstances. I've used Disc Utility to repair the permissions database but am looking for another more specific diagnosis and fix if possible. I can do an archive and install of Leopard if necessary but am not looking forward to it.

Just happened again, this time with Mail not even open. Acting suspiciously like a parental controls issue, even though this is happening on the Admin account rather than one of the kids' accounts. I'll try turning parental controls off altogether to see if it helps.

Can't download Windows spupport software because of a network problem?

Hi all,
Here is my question: I have MBP early 2011 and was trying to download Windows supporting software’s using Bootcamp 5.0 but a box appears saying “Can't download Windows support software because of a network problem” so what can I do to address this problem?
Few more details:
Mountain Lion 10.8.2
Bootcamp 5.0.0
I already tried removing the proxy settings as you can see on the following picture.
Thanks

I tried to select and deselect the Passive FTP Mode to see if that helps as it is recommended by other users before posting my question here to see if that was the problem but that didn't change anytihing. I also tried it before commenting to your response if there was any change and there wasn't any
But thanks for your response.

Bad routers w/MBP C2D

OK, the other thread related to this topic:
(http://discussions.apple.com/thread.jspa?threadID=403194&tstart=0)
is getting kind of convoluted with too much stuff that does not belong in there.
So I am starting this new thread, as well as a thread of GOOD routers that work ok. When posting, only post your router that IS NOT working with the Mac Book Pro Core 2 Duo via wireless, and it's model number. NOTHING ELSE!

My first mbp c2d which I shipped back and a new replacement mbp c2d (pure apple software out of the box osX 10.4.8 + 2006-007 patch, no 3rd party, no data transfered from an old pbG4) randomly drop connections (can easily re-establish, thou) and the signal strength fluctuates between 15 and 5 bars, which cuts the average download speed by 50% (e.g. 4Mbit/s)compared with an old pbG4 which (on the same network) never drops connections and is on average faster (10 Mbit/s ) when close (~3 yards) to AEBS or AE.
In a larger distance (~45 feet) from AEBS the mbp c2d has better signal and download speed than pbG4.
