MacBook :: While Using External Monitor With DVI Kills Wireless Connectivity

Dec 30, 2008

Upon receiving the monitor, I immediately plugged it in to my Macbook, using the Mini-DV to VGA adaptor I already had, for use with projectors. The monitor was good, but a bit blurry and not too sharp, due to the analog signal. So I ordered a Mini-DVI to DVI adaptor. When it arrived, the improved picture quality was immediately apparent.

However, as time went on, I noticed my wireless connectivity was getting terrible. Extremely slow Safari page load times, and upon going to Terminal and pinging my router, I would often get response times of 21000 milliseconds, or worse! I did a lot of research, on router firmware, on wireless connectivity, etc., but to no prevail. Then, on a whim, while continually pinging my router, I removed the DVI adaptor from my monitor. The ping instantly dropped from tens of full seconds to just a stable 0.4 milliseconds! Using my VGA connection resulted in no worse wireless connectivity than without it, but upon plugging in DVI and stressing the connection a bit (i.e. downloading a large file), the connection went bonkers. The pings also immediately jump from 0.4 milliseconds to a range of 1-4 milliseconds, regardless of any "stressing".

MacBook Pro :: 10.6 Recent Update Kills Connectivity With External Monitors?

Jan 7, 2010

Formatted my MacBook Pro and clean installed Snow Leopard after I lost connectivity to any external monitor I plug in to my MBP. I noticed that as soon as I restarted with the Snow Leopard DVD, I regained the connection with my external monitor.

After format all was well until I updated all to the way it was. No problems showed until I loaded the recent update of Snow Leopard.Does anyone suffer from this? Does anyone know a solution?

MacBook Pro :: Connect To External Monitor With Wireless Keyboard

Dec 8, 2014

I want to buy a 19inch monitor for my desk because I am going to start coding and the display on my Mac is too small and I want something a little bigger.

What I want to do is connect my macbook to the external monitor with my wireless keyboard and mouse connected to the mac and then close the lid and the display is on the external monitor. So in other words, my macbook is becoming a Mac mini.

OS X V10.7 Lion :: Kills Wireless To All Other Devices In The House?

Jun 3, 2012

So recently I got a new Macbook Pro. It works great, but as soon as it connects to the wireless internet in our house, my husbands hp computer will have horrible connection. Same for my husbands xbox 360. If he trys to play Modern Warfare 3 or any online game on his360 while Im is connected to the internet, he will have one bar ofI connection and the game will be unplayable. Same if he trys and play diablo 3 on my laptop. Went from 90-110 msec to over 2500+ once  connected.

I know absolutely nothing about macs, so there isnt much I can do there. Have tried connecting with ethernet cords and same thing occurs. Just to be warned I am not super tech savvy, so please explain any ideas to your best abilities.

MacBook Pro :: Drops Wireless Connectivity When Moving Around?

Mar 8, 2012

My job requires me to be mobile, and I move from one office to the next frequently, to attend to various meetings etc.  Every time I move from one office to the next, I have to turn WiFi OFF, and then back ON again, in order for it to re-establish connectivity.  This is a major frustration, as quite often I am downloading or uploading work applications, and have to re-start the download / upload again from scratch.  It's impractical to not move until these are complete.

MacBook :: Safari 5 Kills Flash Support On External Displays?

Aug 12, 2010

I have a blackbook running 10.6.4 with a GMA 950 that I use dual monitors with. If I use the extended desktop mode, and drag a safari window with a flash player onto the external display it will freeze and become unusuable (can't interact with it). The audio will still play through the speakers, and dragging the window back onto the main display brings back the flash functionality. This is a fairly new problem, it never used to happen before.

Hardware :: Apple Wireless Keyboard But Bluetooth Power Management Kills It?

Mar 15, 2009

Sorry to mention the 'W' word, but wondering if anyone has had this issue.

Basically Apple wireless keyboard works perfectly in Windows, but the Bluetooth power management kills it after just a few seconds, which is extremely irritating. It works after you've 'woken it up' again though.

I can't find anywhere to change this, and no joy with a forum search / Google.

PowerPC :: G3 Wireless Connectivity Only When Right Next To Router

Sep 16, 2007

My wife has an iBook G3 500mhz with 320mb of ram. She is having trouble with the airport card that is installed in it. I have a 2.4ghz wireless access point in the upstairs of my house (next to my main machine) which is sending the signal to a 2.4ghz bridge in the downstairs. House is wood frame. She is having problems connecting to the wireless network. When she can actually connect, she has to be right next to a wireless router and even then it doesn't work sometimes to connect. Is the airport card going bad in this? Is it possible that the antenna has gone bad or has a kink in it or something?

Windows On Mac :: Wireless Connectivity In XP Not Above Two Bars

Jul 21, 2009

I get great wireless connectivity under Mac OS X, since the wireless base is in the room right next to the MacBook Pro, but under Windows XP Home Edition with the Mac drivers installed, I never get above two bars, and connection drops every 20 minutes or so. Windows is completely updated, all boot camp drivers are updated, everything.

Mac Pro :: Its Constantly Losing Wireless Connectivity?

Mar 13, 2012

I have a PC laptop which also uses the wireless and has never had a problem.My Mac Pro loses access to the net every few minutes or so. I usually follow a sequence of "Turn AirPort Off" / "Turn Airport On" to cycle the connection, and this works but only for a temporary solution until it drops out a few minutes later.also link to pic here..[URL] It always shows full bars even though in the activity monitor it just flatlines or flutters near 0kB/sec. Like many others, my connection drops although the wireless signal icon remains full. I've noticed that as long as my system doesn't idle (ie - if I'm downloading something, or on a webpage which is always sending or recieving data) the wireless connection seems alright. But if I am on a webpage (for instance, this Apple website which is idle and not sending or recieving data) for a few minutes or am away from the computer for 5 minutes, the connectivity dies and I cant access the net. I then follow a sequence of "Turn AirPort Off" / "Turn Airport On" to cycle the connection, and this works but only for a temporary solution until it drops out a few minutes later. Also, can I ask that NO ONE suggest that I hook my computer up via the ethernet cable as there is no access points upstairs and I'm not going to pay a tonne of money to get one installed when I paid a tonne of money for my "AirPort Extreme" so I didnt have to (which was just over 2 years ago). 

Its been a constant problem for the last 12 months and the short-fix of "Turn AirPort Off" / "Turn Airport On" to cycle the connection has driven me to madness (especially when I write a lot of information into a site for example this, and after 15 minutes I click the next button or send and dont realise the net is no longer connected and I LOOSE EVERYTHING I'VE JUST TYPED. It's happened 1000's of times.

OS X :: Fixing Slow Internet Connectivity With Wireless-N Routers?

Nov 1, 2008

I must admit that this posting is a last resort. However, remarkably, on narrowing the problem it seems it has to do with an unknown default setting on my Mac OS X Leopard on both my MacBook and iMac.

This week I invested in two new Wireless-N routers - Belkin and D-Link - and both fail to perform. The problem manifests itself as follows:

- When my Apple is wirelessly connected to the router, it takes a very long time to pull up any website. And unless I am imagining things, it seems to first pause when the blue progress indicator reaches just beyond "[URL]" each time. It is slow loading beyond this initial pause as well.

- When I change my security from WPA2 to WEP to None, it makes no difference whatsoever.

- When my Apple is connected to the router via ethernet, it performs very well. Each website appears very quickly and as expected i.e. no wireless connection.

- Very surprisingly, when I am using Windows via Boot Camp on my iMac, it performs very well when *wirelessly* connected. This threw me a little. This is what led me to suspect there's a default configuration with my Mac OS X that is causing the problem.

- In light of the above point, I have not yet checked to see whether wireless frequency or channel affect the download speed.

- For 2.5 years I had been using a Netgear Wireless-G router without any problem.

Might anyone know what the problem is? Or at the very least how better to diagnose it?

PowerPC :: How To Access The Airport Card Settings To Get Wireless Connectivity

Mar 4, 2009

I just installed the Airport extreme wireless card on my emac, but I have run into some problems:

1)after installing the card, the mac took a very long time to start up, I tested to make sure it was the card: everytime I started it up without the card, it did the normal thing, but with the card, it took a long time

2)after finally starting up, nowhere can i find where/how to configure the wireless. When I go to configure the network, it has all options, but the airport card option is not usable.

MacBook :: Using External Monitor With New MB (2.4GHz)/monitor Sleep?

Oct 16, 2008

I picked up a new MacBook yesterday and I noticed a weird issue when coming out of "monitor sleep" mode, not regular sleep mode.

When I move the mouse, the external monitor shows what you see in the picture, kinda like a TV with no signal. The MacBook screen works fine so what I just do is unplug and re-plug in the DVI plug and everything is good again.

My 24 inch Dell monitor worked fine with my M1330 and other computers so I know it's not that. Does anyone have the same issue or maybe give me some light on this?

MacBook Pro :: Detects An External Monitor But No Display On The Monitor?

Aug 5, 2009

As said, my current set up is an HDMI - DVI cable (HDMI to monitor and DVI to adapter) and my DVI - mini DisplayPort adapter, everything is connected fine but when I turn on the monitor, it says cable not found... and nothing is displayed on the screen but on the Macbook side of things, it sees the monitor is connected (I can extend the screen and leave the screen) but other than that, it appears I cannot get an image on the monitor, pressing every button on the monitor does not work either.

Any other information that may seem necessary, let me know. I tried clearing my PRAM and clearing the power and such but nothing seems to work.

IMac :: External Monitor - Bad Mouse Tracking When External Monitor Off?

Jan 9, 2010

I have a 27" i7. I have a 24" DVI Montior hooked up to it via MDP->DVI adaptor. When the 24" Monitor is on, everything is fine. When I turn the monitor off, the magic mouse tracking on the 27" screen stutters. I am not kidding - it took me ages to figure out that to fix I either need to turn the other monitor on OR disconnect the MDP->DVI adaptor.

Hardware :: Powerbook With Broken Monitor - Force Boot To External Monitor?

Jan 31, 2010

I have a G4 powerbook with an LCD that only displays the top 25% of the screen. I've been using an external monitor with it just fine. Today, I reinstalled the OS and ran into a problem. The main OSX startup menu (you know, where it asks for your location, timezone, personal info, etc) is prompting me for information, and I can't see the forms to fill them in! The external monitor defaults to "extended" as opposed to "mirrored", and the forms are embedded, meaning I can't drag them over to my external monitor. Obviously, if I can't fill out these forms and get to the desktop, the laptop is completely useless.

Does anyone know how to force the external monitor to be "mirrored" from startup? Is there a keycommand?

OS X :: Monitor Suddenly Goes Completely White / External Monitor Goes Black

Jul 30, 2005

I have been using the latest macbook pro 13.3" since April 2010. Over the last week the monitor suddenly goes completely white and the external monitor goes black. The laptop becomes unresponsive although the programmes opened continue running (e.g a skype voice call would continue without interruption although the monitor is all white).

The only solution at the moment is to press the turn off button for a few seconds then switch the laptop on again. It will then work normally until for no apparent reason this happens again.

OS X :: Lag With External Monitor From MacBook Air?

Dec 1, 2010

I have my MacBook Air hooked up to a 46" HDTV so that I can play games on the big screen.

Problem is, I notice a slight lag with the mouse when looking around in the game on the big screen.

When I look at the game from my MacBook Air there is no lag with the mouse.

I heard theres a mode called "clamshell" that would fix this but don't know where to find it or enable it.

Info on fixing the lag from the big screen so that games could be playable when watching from the big screen.
