MacBook Pro as a Signal Booster?

Hey,
My Macbook Pro (13" Late 2011) has a full WiFi signal at home but my iPhone 5 barely connects to the same network.
Is there a way connect my iPhone to the WiFi through my MacBook? (As a signal booster)
Thanks in advance.

You can share your Ethernet connection to other devices using WiFi. This turns your MacBook into a primitive Router.
You cannot both connect via WiFi and share via WiFi.

Macbook Pro weak wireless signal

I recently purchased a new battery for my MacBook Pro and ever since, I've had terrible wi-fi signal. I've got an iPad, MacBook and iPhone that all have no problem connecting to the network, from all over the house, but with my MacBook Pro, I've got to be within 5 feet of the router or I have no signal at all.
Any thoughts on how to increase the wireless signal so that I can get out of my house again? =)

Hi
I've had a similar problem - see http://discussions.apple.com/message.jspa?messageID=7278377#7278377 . Things continued to get worse, so that sometimes I was losing the signal for several hours at a time: meanwhile my nearby G4 iMac continued to connect with never a hiccup.
In the end replacing the original airport card with a Sonnet Aria Extreme N Mini PCIe 802.11n card has (touching wood, crossing fingers and taking all similar necessary precautions) completely sorted it. No other changes - I'm still using the 11g base station. However, mine was a first revision MBP with an 802.11g card: I guess yours has an 11n card already.

Wifi signal strength on 2012 Macbook Pro

Well after extensive diagnostic testing with other computers, ipad 2 and 3 generation ipad the Wifi signal strength needs some tweaking on the 2012 13 in macbook pro. The signal and download speed is 1/2 the speed of other devices I own the same distance from my home router. I get 10MB/s typically and my ipad gets close to that using Speedtest.net. When the same distance away from the router on the new 2012 macbook pro I get 3MB/s-4mb/s. Way off from what I should get. I have tried several times at different locations. An older MBP gets similar strength and readings close to 10MB/s.
Is there a tweak or does Apple need to tweak somehow?

yes it got better closer to the router. It's signal strength. Bring back?
I would and keep bringing back until I got one that worked like the other WiFi devices you have.

How can I get my 2010 macbook pro to send signal out through the mini display port?

First, what you said is contradictory. You say "can't get a video signal", then say"the Mac wallpaper is broadcast, the mouse pointer is visible". "No video signal" means an absolutely black,blank screen. It sounds like you have plenty of signal.
I am supposing what you are seeing is actually a blank desktop, which is to be expected if your settings are such that you are extending the desktop, instead of mirroring it.
Within the preference panes is a setting that allows you to change this. Open System Preferences, click Displays, and then click Arrangement. You will see that you are extending the desktop. Change that setting.

MacBook Pro and Vizio HDMI problem

I have a 2010 Macbook Pro, a new Moshi Mini DVI to HDMI converter, HDMI cable, and a Vizio VW32L (32 inch HD TV). The MacBook detects the TV, but the TV only shows "Retrieving Data..." for a few seconds and then goes to blue with "No Signal!" showing.
Is there anything I can do? Is there something I don't know that would prevent this from working? Are there any settings on the TV or MacBook I can fiddle with to make this work?

No MacBook Pro uses mini-DVI. It uses mini-DisplayPort if it is newer than a certain generation, otherwise it uses DVI-D. Are you sure you got the right cable description?
What does your Apple menu -> About This Mac -> More info
say about your MacBook Pro x,x model.
MacBooks without the Pro name have used mini-DVI prior to a certain age, and after a certain time started using mini-Displayport. Knowing your exact model will tell us what connector you should be using.
If you are using a Pro and definitely a mini-DVI, I'm surprised your MacBook Pro sends any signal let alone doesn't get damaged in its port.

Help needed to troubleshoot why my MacBook Pro repeatedly drops wifi connection

We run Mac & PC laptops, iPhone, iPad on occasion, with ATT DSL, 2Wire 2701HG-B Router. First 6 months of enjoying my Mac, no trouble. Then things started to go south. Been dealing with this problem of dropped internet connection for over a year. Got a new router--the 2Wire 2701, finally got a new phone line put in from the outside to inside. It now seems like the MacBook Pro drops the signal far more than the PC. It seems worse when I'm at my desk, which is only a room away from the router. It can drop the signal about every 3rd or 4th click on the internet. The Networks Diagnostics will show red buttons on the Server and Internet. Been testing other areas of the house, and find it seems better in these other areas, dropping far less. Hard to tell, because the problem comes and goes, like the sun. iPhone has dropped connection on occasion. iPad has occasional slow download of YouTube. Neither of those are troubling.
I tried checking with the Airport Utility, but it tells me it can't find any Airport. I obviously understand very, very little of this. Any help would be appreciated.

Which os are you using?
Change your router channel. Sometimes this is all you will have to do.
Power cycling the router. Read the router's user manual or contact their tech support for instructions.

Isolated wifi connectivity issues for MacBook Pro

When I connect my MacBook Pro to the wifi at my university only google.com and apple.com load. No other websites will load (including gmail.com). It is an isolated issue to my machine with this one particular network, as my iPhone connect to the same network with no difficulties as do other MacBook Pros and PCs around me. My MacBook Pro shows excellent signal strength when connected to that network.
When I am using my home wifi or wifi and work, I have absolutely no issues with connectivity or loading any pages.
Can give me an idea as to what might be going wrong?

There's a reason why the Finder in the dock is doing this. Click on the icon and tell us what the prompt says.

23" Apple Cinema Display & 15" MacBook Pro?

1) Any ideas on how to crank up the res on a MacBook Pro for external mirroring?
A manager at my company ordered a 15" MacBook Pro & a 23" Apple Cinema Display for the purpose of Mirroring.
When spanning, the laptop and the display look great (and both run in their native modes of 1920 x 1200 and 1440 by 900, respectively), but when mirroring is enabled, the MacBook video card acts like it can't power the 23" LCD properly. It wants to default both the 15" built-in display and the Cinema display at 1440 by 900 - which is unacceptable.
2) Is it possible to close a MacBook Pro's lid and continue to power the external monitor without the MacBook sleeping?
3) Is it possible to toggle the MacBook Pro's video signal to turn OFF the built-in laptop display and ONLY run on the external display? I remember older PowerBooks being able to do this. Many PC laptops will allow you to disable the local video and only send a signal to the external display (for presentations etc).

1) Any ideas on how to crank up the res on a MacBook Pro for external mirroring?
Mirroring is pixel to pixel. The MacBook only has 1440 by 900, so that's all it can show on the external display when mirroring.
2) Is it possible to close a MacBook Pro's lid and continue to power the external monitor without the MacBook sleeping?
Attach the power adapter and an external keyboard and mouse (bluetooth is OK if it's set to wake the computer). When you close the lid, the computer will sleep, but will wake (and continue to run with the lid closed) when you use the external mouse or keyboard.
3) Is it possible to toggle the MacBook Pro's video signal to turn OFF the built-in laptop display and ONLY run on the external display?
Not with the lid open, but if not mirrored, you can move the menu bar to the external display by following the instructions in the "Arrangement" tab of "Displays" system preference.

Macbook Pro Wirless Signal Reception Issues - How to Improve?

I just bought a new Macbook Pro 17" laptop. A few feet away from me is my new Linksys WRT350N wireless router, and I get "choppy" network connectivity at times, moreso recently which leads me to suspect something electrical is nearby that may be interfering with the signal.
Yet, my friend who has a Dell laptop is surfing next to me, and around the apartment, from time-to-time and has no trouble. This has been the pattern for a while.
This leads me to believe that the antenna on the Macbook Pro may need a little boost; using a hardwired has no troubles at all.
I found this "solution": http://www.quickertek.com/products/Quicky.php
I wonder what others' experience has been and what creative solutions have been found that may be like or better than the above.
Thank you in advance.

That model has a max possible RAM fo 8GB (two 4GB modules). As long as you are not doing anything heavy-duty, 4GB (two 2GB modules) is probably OK for Mavericks. I have on MBP running Mav on 4GB with no indications it is struggling for more RAM.
Only buy RAM from a trusted Mac RAM reseller. I use Other World Computing (their RAM listings for your model are here):
http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3
Crucial.com is also good. Avoid Kingston ValuRAM. It has never been happy in Intel Macs. You will get the right RAM from either vendor. Can't say that for brick-n-mortar electronics stores. Too hard to find one with a resident geek who speaks Mac.
Installation is an easy do-it-yourself task; all you need is the right screwdriver. Handy video here:
http://eshop.macsales.com/installvideos/macbookpro_13_unibody/
As for the battery, there is a built-in utility that will show the current condition. Click and hold on your Apple menu. Hold down the OPTION key and the first item with change to System Information. Launch it. When it comes up. find "Power" in the left-hand contents pane and select it to get a battery report. Looks like this:
Copy the information I've outlined in red and paste it into a response to your thread here. Those numbers describe the current condition of the battery.

Mini Displayport to vga adapter on MacBook pro 13" late 2011. No signal on external monitor

Hi
Connecting a Late 2011 MacBook Pro 13" to an external monitor, trough mini Dispalyport to vga adapter, i see "no signal" messagge on external monitor, even if i get it as secondary monitor on Preferences > Monitor of my MacBook it's visible (i can change resolution, position, clone screen, ecc.).
Any suggestion? somebody found the same problem?

Hi
i did what you said and tried with other resolution/refresh rate combinations, also with anoter external monitor (and vga cable) but its still the same: monitor is detected but there's no signal.
Now I will try to chek if the adapter works on other pc and monitor.
Thanks
(anyway it was the firs time i connect this mac to an external monitor)

Issue with MacBook Pro (mid 2009) wifi multiple AP signal 'confusion'

I'll try to explain this as best I can, not being an expert in networking!
I recently upgraded my router from a Linksys WRT160N to an Airport Extreme, in the hope that it would do a better job of broadcasting a stronger wifi signal throughout my house. Whilst it is improved, it's still no good enough for streaming to my iPad 2 where I want in the house. Reading around on the web I discovered that I should be able to use the Linksys as an AP to extend the effective range of my wifi network, as long as it is hardwired into the base station via Ethernet (no WDS support on the Linksys model).
So, I managed to get this all up and running, disabling the dchp on the Linksys, fixed ip allocation etc and using the same SSID and passwords etc. All is well with the iPhone and iPad2 access - they just automatically switch to the strongest signal no problem when I move around the house. Cool.
The issue lies with the MBP - I have a favoured spot in the house where both the broadcast signal from the AEBS and Linksys are very strong, and the MBP gets all confused. opening up the lid from standby it searches for the wifi (bar moving up and down the signal indicator) and then just has an exclamation mark. I try to manually select the SSID but no dice. I have to switch the MBP adaptor off and on, rescan avail networks, and lo and behold two versions of my SSID are shown. Select one and then it connects. However, I have to go through this whole exercise every time I pull the MBP out of standby, which is very irritating.
I do have a workaround - if I name the SSID on the Linksys something different, the problem goes away. However, i effecktively now have 2 wireless networks & I then have to manually switch between the two SSID's to get the strongest signal depending where I am in the house. It's suffices for now but not ideal.
What I don't get is why is it only the MBP affected & the iPhone & iPad 2 are fine? Is this anything to do with the 2.4 ghz & 5 ghz being broadcast by the AEBS getting all mixed up with just the 2.4 ghz being broadcast from the Linksys??? Both 2.4 & 5 ghz are broadcasting the same SSID.
Any help appreciated.

OK - fixed this now. By setting the 5 Ghz channel on the AEBS to a different SSID and putting this to the top of my priority WIFI connections on the MacBook Pro then it ignores the conflict between the 2.4 Ghz networks being broadcast by the Linksys & AEBS. No more hanging connection when I resume the MBP

Why does my Vizio hdtv say no signal when I connect my minidisplay port to hdmi cord between my macbook pro and tv?

My Vizio hdtv says "No Signal" when I use my mini displayport to hdmi cord. It worked flawlessly for a month but randomly decided to no longer work.
I am using a macbook pro from early 2011 running os x Lion 10.7.5 and a thunderbolt to hdmi cord. The cord has worked without a hitch the numerous times I've used it until recently. Now plugging it in will cause the macbook to flash blue quicker than normal and immediately go back to the normal screen. I know the macbook recognizes the TV because changing the input on the TV to the hdmi connected to the computer will cause the macbook to flash blue again, with the same result. The TV remains unresponsive. I have tried all combinations of turning on and off the TV and macbook with the cord plugged in and unpugged from either and both systems and in both hdmi inputs on the TV. I've changed the display resolution to every possible option with no result. The TV is not recognized as a display on either the Display section of System Preferences or the Sound section.
It confounds me that the cord should work flawlessly until now, a month after buying it, for no apparent reason. I've been gentle with the cord, so the problem being a result of damage is unlikely. I had not updated my computer in any way between the successful and unsuccessful uses of the cord, but I have since updated my computer and the problem remains.
I have searched for this problem on the Internet and have seen others with similar problems, but I have not found a solution that resolves my problem. I hope to avoid having to make any additional purchases.
And a thousand and one thanks to any and all who help.

Do you have gfxCardStatus installed? Is your monitor set to "Integrated" or "Discrete". You want it set to Discrete to drive the external HDMI display.
Try resetting the PRAM and SMC

Are you sure you have a good miniDisplayPort to HDMI cable?
Do you have another HDMI display you can test against (your neighbor's HDMI capable TV).
Do you have friend that can test the cable using their Mac and maybe their TV or a monitor that has HDMI input.

Thanks, W

I'm not sure if you understand that 5 GHz has some upsides, but also some very significant downsides.
The upside is that the 5 GHz signal will allow faster speeds.
The downside is that you must always give up something in order to gain something else.Unfortunately, the marketing hype about 5 GHz does not go into very many details about this.
In the case of 5 GHz, the 5 GHz signals are much weaker than 2.4 GHz signals, so they do not travel as far or penetrate any obstructions like walls or ceilings nearly as well as 2.4 GHz signals. In many cases, in order to get good 5 Ghz performance, you literally have to have almost a line-of-sight relationship between your computer and the wireless router.
If you have a new dual band router, which broadcasts both a 2.4 GHz and 5 GHz signal simutaneously, your Mac will connect to the best signal quality automatically depending on its location in relation to the router. In the same room, without any obstructions, it will connec to 5 GHz. But, take the laptop down the hall a few rooms and around the corner and the Mac will connect to the 2.4 GHz signal because at that location, the 2.4 GHz signal is not only stronger, it is also faster.

I am trying to hook my macbook pro to a sony bravia TV via DVI to HDMI cable and the TV will not recognize the signal. The same set up has worked with three other, though different televisions. Any thoughts?

I am trying to hook my MacBook Pro to a Sony Bravia TV via DVI to HDMI cable and the TV will not recognize the signal. I have used the same setup with three other TV's, each a different brand with no problem. Any ideas?

Is the TV set to take input from the HDMI connection?
On your computer, if you open the Displays preferences and do not see an Arrangement tab (or there is an Arrangement tab that shows only a single monitor) then there is something physically wrong with your connection. Try clicking Detect Displays just to see if the computer can now sense the presence of the connection. Check your connections.
If you do have an Arrangement tab, and it shows two screens, then click Gather Windows to bring the TV's Displays preferences on to your main screen if the TV is not yet showing an image. Set the proper resolution (probably 720p, 1080i, or 1080p). Set the refresh rate (probably 60Hz) if that preference is shown. You should see a picture at this point. I recommend turning off mirrored displays if it is enabled.

I cannot get a signal from my MacBook Pro to a Samsung T220HD using an HDMI cable

I was in the Apple store to see how to improve the resolution on my Samsung T220HD, which I had connected to my MacBook Pro using the PC cable and an Mini DisplayPort adaptor. The staff recommended I buy a Kanex Mini DisplayPort to HDMI Cable instead. I've plugged the new cable in, and the Samsung display reads "Check signal cable".
I don't have another cable to test it; am I doing something wrong?

Mini Dis[playPort cables have a lot of contacts, and require a lot of force to seat properly. Push until all the metal part of the plug disappears into the jack.
