Closed lid slow wi-fi/internet

Got a new Thunderbolt display for my MBP, but major issue ...when I close the lid to my MBP the wireless internet becomes EXTREMELY slow. I've read through the forums that the wifi antenna is located in the lid and by closing it the device does not have good reception. I've also read that you can buy a USB wifi booster to potentially fix the problem. BOOO
Here is my issue:
1. Why wouldn't the wifi hardware perform exactly the same whether the lid was open or closed? I thought Apple was known for engineering marvels ...or in this case just standard engineering so wifi would work in all scenarios.
2. Why should I spend $90 on a USB wifi device when the MBP wifi should work with lid closed?
3. Some have suggested get an ethernet hub. I bought a mac and Thunderbolt display with everything wireless possible to eliminate wires!!! Why would I add a hub, with power cable, and RJ45 cable to boot???
If there is any better solutions or fixes from Apple out there I'd love to hear them. Very frustrated ...

Closed Lid Airport Performance

My Sept 2011 MBA with lid closed sees 50% drop in Internet speed & performance. I don't this was the case a month ago but its easy to see now. Other computers on the home network (Airport) see 20 Mbps download speed. So does MBA with lid open. When closed, whether its in its BookArc stand or flat on the desk speed drops considerably. I used an outboard antenna in same room with my 2009 MBP 13" but the driver for the antenna seemed to effect stabilty of MBP. Any suggestions? It should work like this. Connected via thunderbolt to Apple 27" monitor.

Often I notice slow Internet on my computer, so I run a speed test. With the lid closed I'll get a download speed of 2.5 Mb/s, when I open the lid (even just an inch), it rises to 15.2 Mb/s.
I believe that the wireless antenna for the MBP is built into the top portion of the case. I would think that closing the case will affect performance as you would be changing the orientation of the antenna ... and will be especially noticeable at greater distances from the base station as signal strength weakens.
Is there an external antenna I could plug into a USB port or something?
Yes there are at least two vendors, that I am aware of, that offer this type of option: QuickerTek and hField Technologies

MacBook Pro won't turn on after closing lid & fully charged. Help!

I have a MacBook Pro from June 2008, I have been using it all day, this evening it was fully charged and I left it on with the screen open - by the time I came back the screen was black ( I assumed it had gone to sleep) I closed the lid to take it upstairs to discover that when I opened it the power light was not on. When I press the power button nothing happens, but if I hold the power button for around 5 seconds the light stays on, the laptop sounds like it is trying to start up but then dies. I have tried the smc reset, but it has not worked. Also tried taking the battery out and trying this with just power adapter. Does anyone have any clues to what is wrong? Or do I just take it into the apple store?
Thanks, really could do with some help!!

Hey Pascale,
I am not sure if you have fixed this but I had the same problem and found some advice from another website...
http://www.adeepbite.com/lion-seems-having-insomnia-it-doesnt-sleep-easily/
All I had to do was turn off my "internet sharing" (System preferences -> Sharing -> Internet Sharing (uncheck) )
and presto, no more closing lid problems.
If your internet sharing wasn't the issue then I don' t know what is.
Cheers

MacBook (Lion) doesn't sleep even after closing lid

Is anyone experiencing this as well? I have encounter the same problem a few times now. My macbook would have it's fan keep running even when the lid is closed. Isn't it strange? I haven't had this problem before in Snow Leopard.
In snow leopard, even when the fan is running at 6200rpm, as soon as I close the lid. My macbook would be quiet almost instantly. However, with Lion my fan and processor would keep running. Anyone else? any idea?

Itunes slow connection with internet

HELP please someone!
I recently purchased an iphone 4 and so had to get itunes!
I never had the need for it before but I'm quite impressed with it, sorts my music well and works quicker than I thought it would on Windows.
There is 1 issue though, the connection with the internet seem terrible!
I can't stream the 30sec clips of songs in the itunes store! If I download a song it takes at least half an hour! =(
My connection works fine for everything else, normally around 3Mb/sec download speed, often more though! So don't have any issues with anything else!
If I download a song from another source, often takes a matter of a few mins, if not seconds. But itunes seems so slow on the internet!
Really quick to use, just slow as **** on the net!
Any solutions you can suggest?
I've got a Comodo firewall and Mcafee anti-virus and I've added itunes to their safe lists! I can't see what's slowing it up!
HELP PLEASE!
Thanks in advance folks!

How about the built-in Windows firewall - is that also active?
As a test if this was my PC, I'd turn off all firewalls and security to see if it made any difference. You can always turn it back on after the test.
Also I'd try closing itunes in the main account, logging into the windows guest account and see if it is slow there, too.

DVI to VGA Adapter Closed Lid Mode Distorted Picture on TV

Hi
I managed to hook up the DVI to VGA adapter and view on my Sanyo TV. Nothing fancy just a older TV.
I am feeding through the Yellow Video output into the video input on the TV. (Also tried s-video)
Viewing with the macbook lid open no problems. Remembered that I could close the lid.
Followed the instructions online about connecting, closing the lid and waking up using my bluetooth mouse.
First time things went well - able to use Front Row and View Slideshows etc. also steaming video from Safari, (TV Land for my kid)
Then the screen began to flash - and change to black with rolling images.
Like you used to have in the 60-70's black and white TV - multiple images rolling past over and over.
I tried rebooting - starting new connections, using different cables, using both VGA and S-Video directly into the TV and not through my reciever.
Any ideas!
I can't use closed lid mode at all. I must instead, dim my screen.
Help?
Thanks
Buddy

Thanks, BSteely, I have the latest QT and iTunes already. Closing the lid seems to kick the MacBook external display into some special mode that Front Row can't display videos in. For example, you get the Front Row interface, but as you select movies/TV shows, the preview window on the left side is blank. Open the cover, and have both displays going, and you can see the previews fine (and of course, you can see the movies/TV shows play fine as well when you click on them)
Running Quicktime Player full screen works fine without Front Row in either open or closed lid mode. So it is apparently something wrong with Front Row itself.

Updated to firefox 4.0. since then my computer is very slow accessing the internet, websites and getting information from within a website.

Over a week ago I updated my computer to Firefox 4.0. Since then my computer is very slow accessing the internet, websites and getting information from within a website. Also, a tool bar has shown up for YAHOO which I did not request. The old detailed tool bar for Firefox has disappeared. All that now shows for Firefox is the area to enter website urls and an area to enter topic for a Google Search.
Many times I have to exit Firefox and re-enter it later to access the internet.
Please advice what I need to do to get back to the speed I had with the older version of Firefox.
Thank You,
Dennis

TV + Closed-Lid Mode?

Is running in closed-lid mode on the MacBook using a television with the Apple Video Adapter supported? I can't get it to work properly.
Brian

Make sure your power saving settings aren't unusual - I find normal works fine. Configure your external displays with the lid open and then with the power cable connected try closing the lid. It will fall asleep immediately - let it. Then when the light throbs try waking it back up again with the remote... It works for me, but it did try my patience before I came up with a routine that I was happy with.
Also - how do you connect your TV? My TV has a monitor / DVI out and it's quite happy with that. I shouldn't think that S-Video should be too different. Has anyone tried with S-Video? Hope this helps...

Slow response using internet, just hangs

Not the best at IT and just clicked update when it came up as available without realising what I was doing! Turns out it was an upgrade to os x 10.9.4. Since then the laptop has been practically unusable particularily when it comes to safari, it is either really slow getting to a particular page or just doesnt do anything, no matter how long you wait. Restarting doesnt seem to help, reload view fails as well. Its strange as sometimes its ok for 10 minutes then starts doing this. I know this is bad but I have never backed the laptop up so cant restore to previous version. I am currently looking into which external hard drive to buy so I can start doing regular back ups. I have run EtreCheck in the hope somebody can help!! Results below

My 1st Generation time capsule won't connect to the internet thru a new motorola sb6121 - get continuously flashing yellow light. Using a router in between the modem and capsule yields good but slower connection to internet. Any thoughts?

My 1st Generation time capsule won't connect to the internet thru a new motorola sb6121 - get continuously flashing yellow light. Using a router in between the modem and capsule yields good but slower connection to internet. Any thoughts?

Thanks for your response
Let me give the history - I started with an Apple Express being fed thru a D-Link EBTR 2310 cable Router from an RCA DCM315 Modem (Pure). Comcast service all the way.
Got the 1st generation TC in 2008 and merely replaced the Airport Express with the TC. Worked ok
A year or two ago I did try removing the modem and feeding the TC directly from the modem. Resulted in the same condition I have now - Continuous flashing amber on the TC. So I put the router back in the chain.
Some time later, at the recommendation of a Comcast rep, I replaced the router with (a Belkin F5D 5231) to see if speed and dropout problems would be improved. I thought it helped some at the time but now I am not so sure.
Last week I decided to see if a new modem would help with download speeds. So I got another pure cable modem (Motorola SB 6121- high on the Comcast recommended list).
Got up and running easily with Comcast help and with the modem connected directly to a computer.
Next I put the TC in the link and again could not get past the TC continuing to flash amber. Although I did get connected to the internet with this configuration I lost connection two both of my printers - one connected by USB and the other wirelessly to the TC. Again everything works fine when I put the Belkin router back in the system.
However with the router in there, the modem shows the downstream connection to be 10/100 ethernet speed. (Modem light changes color for indicating speeds.}
I have gone thru all of the combinations of powering down/ up, but all stays the same.
I can live with what I have but something still doesn’t seem right.
Thanks again

10.5.2 wake/sleep and closed-lid problems

As of 10.5.2 my MBP no longer works correctly in closed lid mode using a hardware
setup that previously worked flawlessly. After plugging in power and video, plugging
in the USB keyboard seems to wake the system, but no video. I then must open the
lid, unplug the USB and video and try to get the system to respond. I often must cycle
the power to reset the system--very disturbing to do that.
Also as of 10.5.2, I have had to power-cycle the machine when it has refused to wake
in open-lid mode and this weekend I the entire machine froze (no mouse movement,
no expose, etc) in the middle of work using a graphics-intensive program and I had
to reboot by cycling the power.
A friend also reported similar issue in which the system would not respond after the
screensaver became active.
Are others seeing problems like these? I am beginning to suspect that the post-10.5.2
graphics update has problems.

I just wiped my HD and reinstalled everything besides the Graphics Update. I can now close the lid of my MBP and use my external monitor alone. The Graphics Update had made that impossible.
Further, I am in the habit of putting my MCP to sleep and putting it in a backpack in the morning, meeting friends for breakfast, and re-awakening it at the office. When I did get to my office, I found (as another user had on another thread) that the MBP, even closed, had woken itself up and was hot as heck. I am uncertain that sleep will work properly under 10.5.2, but I know that the display wackiness of the Graphics Update was driving me nuts. I will not install it until Apple fixes it.
I looked around for awhile for a way to uninstall the Graphics Update, but could not find it...I suspect it exists somewhere.
The 10.5.2 Combo update (343MB download) DOES NOT include the Graphics Update, and at this time, I seem quite ok with everything else updated.

15-r007TU-Display does not turn on when it automatically turns off after closing lid.

I just purchased hp 15-r007TU, Windows 8.1 x84. I'm facing a strange problem. After all initial setup, I put the laptop on to download and install all lates Windows 8.1 patches. The display is set to tuen off automaticaaly after 5 minutes. After 5 min it did turn off as set. But then I can not turn it back on. I pressed all (except power) keys, used touch pad, closed lid and opened but it stayed off. Laptop was on and running as I could see HDD lights flickering, I could hear system sounds on pressign mute/volume keys, also I could toggle WiFi with key. I then pressed power off key to turn Windows off normally. I did turn off. I again turned it on, I could see 'hp' logo with spinning wheel and then nothing. Display is off and I don't see start screen. I have to hard reset (press power button for more than 5 seconds) then display is normal. This happens every time the display turns itself off automatically after set time or I close the lid. Only after hard reset it works normally and I see the start menu.
The power settings I use are:
1. never put system to standby after preset time. (either on battery or AC power)
2. turn display off after 5 min. (both on battery or AC power)
3. when I close lid - do nothing. (both on battery or AC power)
4. when I press power button - shut down
I am using Windows 8.1 x64 with all latest patches installed. BIOS updated to lates available. All latest drivers installed.
I have not yet set password to the system to log in.
Help would be immensly appreciate. The device is still in warrenty if it needs to be replaced.

Hello K1200LT,
Welcome to the HP Forums!
I understand the computer will not sleep when you shut down the lid. You seem to have already done most of the troubleshooting I would've suggested.
To be honest, it is either a hardware or software-related issue. To determine this, I would like you to reinstall the operating system. It will clear up any software conflicts and allow you to start fresh.
First, please ensure you backup your files. Here is information on how to do this: Backing Up Your Files (Windows 8)
Once this is done, it is safe to reinstall the operating system. Performing an HP System Recovery (Windows 8)
If the same situation occurs, the computer likely has faulty hardware. At that point, please contact HP phone support. You can utilize this website to learn how to contact HP appropriately, based on your region: Contact HP Worldwide
Please let me know what happens. Thanks!
Mario
I worked on behalf of HP.

Closed Lid Operations Wont Work

I am a big fan of the closed lid with external mouse, keyboard, and display (minimize spill risks in college dorm room). I just got a new macbook pro after 4 great years with my g4 powerbook and I cannot get the new machine to work with the lid closed. I have tried working with both displays then closing it, but it won't wake up. I tried putting it to sleep and attaching the external display but it doesn't wake up. The for either if I try to open the machine to use it normally the built in display, keyboard, and trackpad are non-responsive and so are all my external items. Has anyone else had this problem or any ideas on what could be going on.

Jonathan , I am experiencing the same exact problems with my Macbook Pro 15 inch. I first started noticing about a month ago that the computer was getting unusually HOT to the touch , and after one day I set the lid down, when I tried to open it back up, it remained on , but no screen, and unresponsive. I have had to restart it everytime since then. It also now takes a lot longer than usual to reboot. I hope the people at Apple resolve this soon, because this is WAY too expensive to be having these problems on a new machine Ive only had for 5 months.

Closed lid, fans always running

Howdy. I've been using my MBP in closed lid mode attached to a Cinema Display. I expected the fans to run constantly when in use, especially with XP running in Parallels. When I put the computer to sleep--still attached to monitor, usb keyboard, bluetooth mouse and power adapter--it acts as I suspect it would, fans stop, front LED starts fading in and out. However, I'll come back later and the LED will be solid, display blank, and the fans running away. The keyboard or mouse will wake the computer and then it runs as normal. This has happened overnight as well as in half an hour, and several times.
I am kind of getting concerned about using the computer this way. Fans always fail, and I am not really looking forward to opening the computer up again.
I guess my questions are: why would the computer be running the fans, especially after being in sleep for hours, and is it shortening my MBPs expected life using it with the lid closed?
Thanks.

I'd guess/assume that something is actually waking it from sleep and causing the heat/fan activity and that when you return you're not actually waking it up just re-activating it from screensaver mode ...
Run Utilities/Console and click 'All Messages' top left - what lines appear during the time you think it should be sleeping ?
It isn't shortening the life of the hardware using it in clamshell mode but if something is causing it to overheat regularly that will have an impact on internal components/motherboard that could be detrimental.

EXTERNAL HDD NOW DISAPPEARS WHEN USING MY MBP IN CLOSED LID MODE

I have an 15" MBP 2.53 running Snow Leopard, which installed fine. When I go to use it with my Apple 24" Display and my external hard drive, the external HDD disappears when I go into closed lid mode.
The finder freezes too, and I can no longer enter into Time Machine.
The external HDD does show up in disk utility, however.

and please ... STOP SHOUTING!
It doesn't make your message any more relevant or increase the motivation to help you. To be honest, it makes you look like a moron, if anything.
Cheers,
Jazz
