I recently bought a Macbook Pro (my first Mac). I'm having a problem whereby it keeps disconnecting (a few times a day) from the internet. When I click on network preferences -> Assist Me -> Diagnostics... the ISP, Internet & Server lights are red. I click continue under airport, select my network and it then says my internet appears to be working which it does until the next time.

After downloading Yosemite, my computer (macbook pro) keeps disconnecting my home wifi. I had no problems with my wifi before and my roommates have no problems with it still (they do not have macs). This is only happening at home though, when I go anywhere else, my wifi stays connected. I have tried deleting/forgetting my wifi network and reconnecting, restarting my computer, i searched through my settings but I don't know what to do. It disconnects like every two minutes. When it disconnects and i go to reconnect, the wifi is still there and has full bars, my computer just doesn't stay connected to it.

Is there any reason this would keep happening? Is there something I can do to stop it from happening?

I have a 2.3 GHz MBP bought in 2011. It sits on my desk with the power adapter plugged in and I have a large monitor, keyboard and mouse attached. Typically every weekend or at least every other weekend I disconnect everything from the MBP and carry it around for a day or so until the battery is less than half charged. Then I reconnect everything and let it charge up.
1. Is what I do necessary and if so is that frequency of recharging sufficient?
2. Is it advisable to do a shut down before disconnecting everything and again before reconnecting?
3. If letting the battery run down once in a while is advisable, as a mater of convenience could I leave the MBP connected on my desk and just remove the power adapter, so it would still be connected to the monitor, keyboard and mouse just using the battery, and then reconnect the adapter when the battery is low?

My macbook pro, running on osx mavericks, disconnects from wifi for no reason. This happens often, but I can't find a solution. I have tried making a new location and deleting all my networks in the network preferences. I have also uncheck "wake for internet access" in the energy preferences. I have reseted my computer multiple times.

Macbook Pro (Mid-2012) Which I purchased 4 months ago.
It keeps dropping the signal about every 5 minutes, only on my home network. It's only this device too, since my phone and all of my roomates' devices are unphased. (streaming videos like it's no big deal)
This started happening after we lost connectivity with the snow a few days ago here in Seattle. I have tried all sort of troubleshooting, including the DNS thingy and restarting the router.

After upgrading to Yosemite 10.10.1, my MacBook Pro has been randomly disconnecting from the WiFi access point. Nothing has changed settings-wise, and none of the other devices have the same issue. Here's my log when it disconnects:
12/9/14 12:11:52.000 PM kernel[0]: AirPort: Link Down on en1. Reason 8 (Disassociated because station leaving).
12/9/14 12:11:52.000 PM kernel[0]: en1: BSSID changed to 00:00:00:00:00:00
12/9/14 12:11:52.000 PM kernel[0]: en1::IO80211Interface::postMessage bssid changed

Lately I've been noticing that my Airport disconnects about every 10 - 15 mins or so and then reconnects after it searches for a network, which is mine. 99% of the time I'm sitting right in front of my router. I've reset the router, rebooted, reset my pram, and the problem still persists. This issue doesn't occur on my girlfriends HP.

This issue started to appear few days ago, and it is really frustrating.
Every couple of minutes, my Airport disconnects from the networks and reconnects in a matter of seconds, causing all of my on-line activities to cancel, and IM programs to disconnect.
And the main concern is that I've had my Macbook for 2 and a half years already, and this never happened before. And now happens all the time.

kernel panics after using my MicroBook II USB interface with either Logic Pro 9 or Pro Tools 10, or even standalone programs.
My macbook is a mid 2012, 4 gb, 2,5 ghz i5 with OSX 10.9.3
The only way to really avoid this, that I've found, is to close every application and then disconnect it, but this doesn't work every time.
it would be nice to be able to disconnect the USB Interface without getting the "grey screen".

Mac OS X 10.8.5 crashes after I disconnect the thunderbolt display.
I normally work in the studio with my macbook connected to an external display.
When I go to use it without the thunderbolt display it crashes - 4 times in one day.
I've checked my log files and I have a list of panic reports. each of the reports refer to the graphics control.
GPU Panic: [<None>] 5 3 7f 0 0 0 0 3 : NVRM[0/1:0:0]: Read Error 0x00000100: CFG 0xffffffff 0xffffffff 0xffffffff, BAR0 0xd2000000 0xffffff808013e000 0x0a5480a2, D0, P3/4

I have a dual Thunderbolt setup (chained). When I disconnect my Macbook Pro (Early 2013, Retina 15", 2.8 GHz, i7, 10.9.4 (13E28)) and open the lid, the display back light comes on but the screen remains black. I can hit caps lock and the light toggles. But, I never get beyond the black screen to a login. I need to do a hard reset (holding down power button) to recover every single time I disconnect from my displays.

Had my iPhone 6 replaced today from an authorized service provider.
Wanted to sync the iPhone to my Macbook Air but when I connect it, it keeps on connecting and disconnecting.
I tried to..
1. Insert the USB cable into the other port (there are 2 built-in ports) This did not work; problem persists
2. Plug in my iPhone 5 into both ports The iPhone 5 is able to connect with no problems.
3. Plug in my iPhone 6 into another laptop with iTunes installed. The iPhone 6 is able to connect with no problems.
It was only after some minor fidgeting with the end of the USB cable (near to the phone) that I am able to sync, but this is not a perm fix.
Is it my Macbook Air's USB port that is causing the problems? Or is it my new iPhone 6? (although I am doubtful since I can connect to another laptop)

I notice that every time I close the lid on my MBP the machine goes to sleep, and the wireless connection disconnects. Is there any way to stop this behaviour so I can say download large files and such even while the lid is closed?

I tried to re-apply the thermal paste myself but when it came to disconnecting the wire connectors from the logic board, 3 of the connectors came off completely from the logic board or has damaged the pins. (the battery connection, and two for the left fan)
I have a feeling that these three became brittle or weak from the heat that was generated from the laptop (hence i wanted to do the thermal paste mod). Or it's just my stupidity that these broke. But the others came off without a problem.

Simple question to you guys with multiple monitor setups:
How does the OS resize/rearrange windows when connecting/disconnecting the Macbook Pro from the larger display? I'd imagine it'd have to do something since the resolution on the larger monitor is much greater than the MB screen.

I recently installed OSX Lion and everytime I plug in my WD external hard drive it disconnects it a few minutes after pluging it in. I did some troubleshooting by pluging the hard drive into another mac book that hasn't been upgraded to OSX Lion and it wasn't disconnected. I have my entire itunes library stored on this hard drive.

I was just wondering if any other macrumorsmembers have been in the situation where there's no wifi, no decent 3G, but ethernet ports available to use, but you don't have a computer handy? Would it be possible that you could create an ethernet cable one end, dock the other, and literally connect e.g. an iPhone into the ethernet? At my place of work, there's no signal (dodgy GPRS/flakey Edge), some wifi, but in halls of residence, you get 1 ethernet port, and you can't put a wireless router onto it. It would seem that it would be an interesting solution, if it was possible.

I just bought an airport extreme w/gigabit, and I'm wondering if it's possible to connect an ethernet switch to one of my pro's ethernet ports and have things like my xbox 360 and ps3 run off it, however, my mac pro would be connected to my airport extreme via 802.11n. is that possible?

First of all here are are the Specs on it
Specs:
Blueberry Colored
iMac DV
PowerPC G3 400 MHZ
MAC OS 9.1
10GB HDD
512MB SD-RAM
10/100 NIC
56K Modem
4 X Slot load DVD-ROM Drive
two USB Ports
USB Keyboard/Hockey Puck mouse (Which I hate luckily any USB Mouse will work)
External VGA Port
It was given to me because the built in CRT came on purple every other start up Now it will not come on at all even though I can still hear the loud noise from the Degauss cable and the Power Supply and I feel the tube still throwing off alot of heat like a CRT does. I can get a picture on an external monitor as a mirror but not as a main monitor. So three questions is it safe to use this way with an external monitor and the built in CRT still attached? and how would I go about disconnecting the Built in CRT?, is there any way to fix this? Currently the HDD is blank as thats the way it was given to me but I was also given the restore DVD of OSX 10.4 from another Mac.

Have an iMac running SL 10.6.8 and every few minutes my internet connection is interrupted. But airport shows connected to my network. I have to open network preferences and it shows airport connected but ISP and Internet will be yellow or red. Then I have to go to the Diagnostics button and Airport will be green. I then hit continue and wait for my network to show up in the list and then rejoin. Then I have internet for a bit until it happens again. All other computers and devices on this network are fine. Must have a corrupted file on this iMac.

I'm just upgrade to Snow Leopard and it work great except one problem, when I turn of my second external screen (a TV using HDMI) I get a kernel panic and there is no crash log for it in /Library/Logs/PanicReporter I've done the "usual" resets on PRAM, NVRAM and SMC however this didn't do the trick. I didn't have any of this problem in Leopard, so anyone else have the same problem in Snow Leopard or have any ideas of how to solve it, I would love to hear it. I thought I should mention I using HDMI for images and TOSLINK for audio that goes to my receiver and then to the TV So when turning off the receiver or the TV I will get kernel panic.

For the past day of so I have been trying to backup my files, I am not using the Time Capsule but an external HDD for backups etc. But since the new update of 10.6.2 it keeps disconnecting my hard drive after about 10 seconds. I have tried to quickly do a disk utility check on it, but its not on the list. Is there anyway to get a new driver for it or something as i have important documents on there that need to accessed.

I have a 2009 Mac Pro ("Cyrus").
Connected to it are via USB and video an Apple Cinema Display.
Connected to the Cinema Display are an apple keyboard and to it an Apple Mighty Mouse.
Sometimes the mouse pointer freezes (or rather is found frozen when I return to the machine and the screen saver was on) and the only way to get it back to work is to disconnect the mouse and reconnect it.
However, every second or so time I do this, the Mac Pro crashes. The screen turns darker and in the middle a multilingual text tells me that I have to restart my Mac.
Does this happen to anybody else?
How can I prevent it and why does Mac OS X crash over a USB event?
