MacBook Pro :: No Wifi Connection With External Monitor?
Aug 25, 2010
My problem right now is, when i connect my macbook to my hp external monitor wake the computer up in closed lid mode, my internet connection is lost, and it doesn't come back unless i restart my computer.
I'm using the new airport express.
how can i make it so i can connect my external monitor, use it in closed lid mode, and keep my internet connection
But it work in that scenario with the lid open.
I'm just trying/wondering how to figure out lid closed while can be connected with the wireless connection.

Did any of you experienced this ? My WiFi slows down or even stops working when external monitor is connected (via the big connector, don't remember it's name, DMI or something like that). Air Rev A, 1.6.

I have a strange problem with a WiFi slowdown when connected to a TV. Here are the specs of the equipment:
2.2 Ghz white macbook, santa rosa, 4 gb ram, purchased January 2008
Panasonic TV connected via HDMI to DVI cable + Apple Mini DVI to DVI connector
USB Western Digital harddrive connected to a 500 GB Time Capsule (1st edition, no dual channels)
Snow leopard 10.6.1
Before upgrading to snow leopard, I would frequently use the macbook to provide video to the above mentioned TV streamed from a hard drive connected to an imac (connected to the same time capsule). I moved, and upgraded to snow leopard, and haven't tried this until finished setting up my equipment yesterday. I can stream videos to the macbook from this hard drive fine when nothing is connected. However, the moment I plug in the mini-DVI connector, the WiFi drops to a crawl. This applies not only the to air disk but any data from the network (internet, etc.)
A couple of additional notes: Display is set to mirror. Has nothing to do with clamshell mode because the macbook isn't closed. Nothing to do with location/interference- the effect is instantaneous with plugging and unplugging the cable. The base station is actually closer than in my previous setup and is pretty much 20 feet away in direct line of sight. I connect to another external monitor daily at work (vga, again with apple mini dvi to vga adapter)- no issue whatsoever restart did not help. I canceled all time machine backups over the network to limit that as a factor- no effect.

I have an 09' 13 inch Macbook Pro and I want to get an external monitor so I can use my laptop screen and the monitor at the same time for more space. What type of connection capabilities should I be looking for in the monitor to ensure that my macbook will be able to connect with the monitory?

I recently purchased a 21.5" Samsung monitor that is connected to my late 2009 13" 2.26GHz 8GB RAM MacBook Pro through a VGA connection with the VGA to Mini DisplayPort adaptor. Since I've started using it, my Internet connection has slowed to a crawl. I've researched the issue online and external monitors can apparently created wireless interference. I'm using a 2011 AirPort Extreme 802.11n/b/g. Is there anything I can do to eliminate this interference?

I have recently purchased the mini display port to DVI adapter and a Belkin DVI to HDMI cable, to plug into my MacBook & Samsung SyncMaster 2032MW monitor. However when I connect this all up the display resolution is appalling, blurry and doesnt fit the screen. I have tried all the available resolutions turned mirror-mode on & off and its still shockingly bad! Also tried this on my LG TV and still the same. I have a Dell laptop which I connect via HDMI and the resolution is amazing. I thought the MacBook would output the same?

However Ive just bought a LG M2794D 1080p tv/monitor and now have a problem. The TV is showing it recognises when the HDMI cable is connected to the macbook (on the screen the input menu shows live connections) or not through HDMI cable and mini-DVI to HDMI connector but the macbook does not recognise any external monitor. In display preferences there is no arrangement tab either and no resolution greater than 1280 x 800. Of course the TV has full 1080p resolution.

I have a Time Capsule wirelessly connected to my iMac. Since I've encountered some problems with backups because of intermittent wifi connection failures, I want to switch to a wired connection with an ethernet cable. I know I could fiddle with the wifi channels etc. but since the TC is just sitting next to my iMac anyway, I could profit from the higher bandwidth of a wired connection as well.Two questions:
1. What exactly do I have to do to make the switch? Are there any new settings I have to apply? Create a new network?
2. Will I still be able to use the wifi connection to get on the internet using my smartphone?

Just got a new MacBook Pro, and it is having wifi connectivity issues. Every time I fully shut down and restart the computer, it will not connect to my house's wifi. Rebooting the wifi solves the problem. This didn't happen w/ my old macbook, and no one else in the house is having wifi connection problems.

MacBook Pro (13-inch Late 2011), Mac OS X (10.7.3)

I don't have WiFi internet at home and have an Ethernet cable plugged into my Mac Book Pro from my modem. From there I can use the Mac Book Pro as a WiFi transmitter and can surf the net on my iPad and iPhone using the Wifi from the Mac Book Pro.When I try and connect my XBOX One via Wifi to my Macbook Pro the Xbox one detects the Mac Book Pro and after I enter the password it mentions something about a MAC error.

I have recently had BT infinity installed and ever since, I lose internet connection on my Mac. When asked for the WPA password that I was supplied with, I put this in, but it says it is invalid. The only way to get a conncetion, is to press reset on the router. Then the same things happens the next day. We have tried changing the channel, frequency, etc. I thought it might be a setting on the mac...

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?

I have a 22" Dell external monitor on my MBP. I know that I just close the cover to my MBP to shut off the screen. What do I do in those instances that I want to use both screens? There has to be something simpler than restarting the MBP?

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.

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.

Evey time it goes to sleep or I turn it off it forgets the fact that there is any wireless around. I have to look for the networks. Then if it wants to will find them and trying to connect to my own wireless network (apple extreme) is a challenge. I do have parallel desktop installed, could that be the problem?

I have a 2 year old macbook that just refuses to connect to my wifi, I also have 4 other apple devices that connect seamlessly. it registers the network, it joins the net work and then fails, I have had several different error messages as follows while re entering my password I get a dropdown box saying I have changed settings, this then sends me back to the preferences to start again. and then i get error message that my password is incorrect (I can confirm it is correct) I have also been to the genius bar, and we managed a connection for the duration of the visit ( a healthy reading too apparantly)they carried out a hardwear diagnoistics check and it was given a full bill of health. I was advised to insert the reinstallation disk and carry out a reinstall - I have done this and the problem is still there.
