Fix for wireless connection issues on MacBook Pro - reinstall OS!

I hope this helps some of you out there.
I was having all the usual problems with connectivity with the MacBook Pro I bought in January 09. It dropped the signal constantly and if I closed the top, it would make me search for my network again then it would give me the "connection timeout message" over and over again. I couldn't get anything done either at home or anywhere else. I finally took it in to the genius bar but they couldn't replicate the problem so I was sent home. The guy did, however, suggest reinstalling the OS (which I thought was a dumb idea since it had to be the airport card right?). Since it was a week away from the release of Snow Leopard I waited.
Once I installed Snow Leopard all was fixed. It has now been almost 2 weeks and I haven't lost a signal once - the difference is amazing. I feel liberated!!
Try a reinstall or upgrade to 10.6. and good luck. Post here to let us know if it works for you. Don't forget to backup your date first!

Nope I'm not trying to tether. I would like to be able to use a wifi connection on my mac and other devices. I've gotten by so far just hooking up my mac to the ethernet port, but that requires me to be in my room. I know its possible since there a bunch of networks nearby (locked of course), but I just can't figure out how to get mine working.
I'm living in an apartment across the street from campus that is sort of school-owned...well its private but the internet service is provided by the campus since only students live here. So we have to register anything that we want to use on the school's network. On campus I can use wifi on my mac or iphone. Its troubling how I can use the ethernet cable just fine, but when I connect it to my router (which I registered through the school as well)...nothing. Technically this should be working easily - but maybe you're right on the network security accessability...or maybe my router is old...or my mac doesn't like my router? I've had this problem before during my undergrad years except I was dealing with a cable provider and not the school.
Maybe I should just make friends with my neighbors and find out how they set up theirs haha.

Wireless connectivity issues with Macbook Pro and At&t service HELP!!!!!

I have three Computers two PC's and one Macbook Pro( the latest model).My desktop PC is used by ethernet, my girls laptop is used wirelessly and finally my MBP was being used wirelessly.
I started off with only the two PCs and my internet connection never had a problem and I was doing everything from: on the internet to downloading.
Before I bought my MBP I had also switched from internet and phone bundle to just internet from At&t service. So when I got my first MBP I notice that I was loosing wireless connection with both my girls pc laptop and my MBP so i thought it was because I had just switched service, though they send out a service technician and we came to a conclusion that it was the MBP. (I was loosing signal via wireless and ethernet). So we tried to see if both my girls laptop(wireless) and my PC desktop (ethernet) would run into the same issue which it did not.(MBP was turned off)
So I decided to go my nearest Apple store and let them know what was going on. So I told them what was going on and they said It must be the airport card, and they ended up changing it. When I get home I discover that not only I am having the same issue but other issues too. I went back they ran some diagnostic and they said it was defective and they gave me a new one few days later.
So in the mean time that I waited for my new one to arrive I used my PC desktop and my girl kept using her laptop and guess what no issue what so ever for one whole week. Now I receive my new MBP(they bumped the specs a little), went home set it up and still the same issue though I dont have the issue when Im using via ethernet. Just a view minutes ago I tried removing the ethernet and using the airport/wireless and within a few minutes I lost the signal.
I have the gateway 2WIRE model(2701HG-B) modem/router.
Is there something wrong? what do I have to do to make this work?

Hi Guys, I bough my Mac almost two years ago. All this time I have experienced the same issue. There are tons of discussions re this issue in the internet. Unfortunately, Apple has done nothing to fix it. I have tried a lot of different options, but they work no longer then 1-2 days. The official fix - does not exist so far. It is quit strange, isn't? I can share my experience: if you go to AirPort Utility - Manual Setup - Wireless and then change Channel, it could help you till the moment you restart your computer; next time you need to repeat it again. It takes 2 minutes. Not sure that it would work for you but you could give it a try. Well, not the best option. Anyway Apple must fix it asap! Hello Apple, do you hear us? Good luck.

Wireless connectivity issue between MacBook Pro/ iTouch and Airport Express

I'm creating a wireless network at home using my airport express and depending on the configuration settings I set in the airport utility, I will face the following issues:
1- To connect my MacBook Pro to the wireless network created, I have to set the radio mode to 802.11n only (5 GHz). Any other radio mode (a/b/g compatible or n only (2.4 GHz)) will not work ("Couldn't find the network")
2- Conversely, the use of the radio mode 802.11n only (5 GHz) with my iTouch doesn't work ("Couldn't find the network"). To connect my iTouch to the wireless network created, I have to set the radio mode to 802.11a/b/g compatible or to n only (2.4 GHz)
As a result, I manage to 1) either connect to a wireless network created with my airport express with my MacBook Pro only 2) or with my iTouch only, depending on the configuration setup.
I'm using the latest updates for the airport utility (7.4.2), iTouch (3.1.3) and Mac OSX (10.6.4).
Any help on this?

if you set it to the most compatible with the least common denominator you should be able to connect with both. (If that's what I understand you are trying to achieve).

Wireless Connection Issues with Macbook Pro

Maybe this is an OSX issue, but I'm not too sure. I'm trying to set up a wireless access point through my school's internet, but I'm having some issues. They provided information on how to set up the router, so I did just that. However, when I connect and try to visit a webpage, I keep getting "Wi-Fi has the self-assigned IP address 169.254.....(don't remember the rest) and will not be able to connect to the Internet."
I'm using the Linksys WRT54G v6.0 and I set up the network to the school's liking: disabled DHCP (so users are forced to talk to campus in order to connect) and enabled MAC filtering. My computer and router MAC addresses are registered with the school so I can access the internet. Ethernet works just fine on my computer, but I would like to be able to connect my iPhone and iPad to WIFI while I'm at my place.
I feel like the problem has to do more with my computer than the router since I've had these issues on different routers with other Macbooks while my friend's PC's worked just fine to connect.
I contacted the school's IT, but they won't help me when it comes to personal routers. Oddly, there is a separate IT for residence that offers help, but they're closed for the day.
Any suggestions?

A Fix for Wireless Connection Problems

I’ve been struggling with connection problems for a week. Thankfully, I found a fix. Your mileage may vary, but this may be your answer:
Fix for Wireless Connection Problems on MacBook Pro

Yeah BR, please tell me what your cure is. I have the same setup as you, Vista with the same wireless card you have. Cannot stay connected to the internet. Have spent hours on the phone with tech support and they can't fix it. I hate this f....ing computer, will never buy another one. Please let me know what you did. Once I get it running right I'm selling it and will buy a cheap Dell, never have any problems with them. I have keyboard problems, capital letter problems, connection problems, and download can take 1 to 2 days. Pure BS!!!!!!!!!!!!!!!!!

Is possible for me to use the wireless connection from my Macbook Pro

Hi All, I just got my iPad 16GB WIFI and I would like to know if it is possible for me to use the wireless connection from my Macbook Pro. Basically I will be travelling quite a bit and my Macbook Pro has a Wireless 3G dongle. Is it possble to use this via the 'internet share' option so that the iPad can connect to the 3G wireless via the Macbook Pro?

Yes. Just use internet sharing on your MacBook Pro.

Wireless connection of a Macbook Pro to a PC wired to a cable modem

Hi all, I am planning to connect my new Macbook Pro to a wireless network that I will be setting up in my home. Currently I use a wired DSL cable modem that is connected to my PC. My Macbook Pro will be downstairs (wireless) and my PC is upstairs where the cable modem outlet is. I will also want to connect my PC's printer to the wireless network so that my MBP can use it. So....are there any issues I should be aware of regarding connecting, speed issues, compatibility issues, bugs, etc?
Also, what hardware (router, ethernet hub, air-port, etc) do you recommend to make this work? (Mid-range price.)
Thanks very much.

not mid range price but usefullness and functionality for usb connected printers and hard drives and usage for Time Machine backup....Apple Extreme N router educational buy about $165.00

Connection issues with MacBook Pro and DVI to component video

How do I connect a 2007 macbook pro to a regular tv (non-hd) via the DVI port with component cables? The image is always scrambled. The connections are fine, what do I need to do?

Concerning this comment:
I know that neither the adapter nor the VGA cable have a problem since I connected the computer to my 1080p TV and it worked just fine...
I would like to point out that 1080p has a lower pixel clock than will 1920 x 1200. So it could be the stability problem is only present when the pixel clock is at the high end of the range.
You could return the adapter and try another. A new one might have better margins. Another thing you could try is to use a utility like SwitchResX to lower the pixel clock and see if stability improves.

Wireless connection lost after macbook pro sleeps for more than 15 minutes

It's annoying. I have a brand new macbookpro 3.06Ghz 17" hi-res screen running OS-X 10.6.3 and the wireless connection keeps dropping after the computer is either turned off or sleeping for more than 15 minutes.
My router is a linksys wireless G, has dd-wrt software in it which is very powerful. When I release or renew the DHCP at the router, the mackbook connects to the wireless network, no problem.
What configuration can be done at the macbook as to not have it time-out airport wireless connections unless I renew/release DHCP at the router? This is an annoyance beyond the limits of anyone's patience.... Thanks in advance for any help!

Well, since nobody answered this post I decided to try a bunch of things and I believe I came to a solution:
1 - Make airport the first connection under System Preferences->Network
2 - In the advanced window:
- Under AirPort: Keep only one network name on the list (the one you use all the time)
- Select 'remember networks this computer has joined' and deselect all other boxes
- Take note of the Airport ID (xx:xx:xx:xx:xx) and put it in your router's MAC address list. I do this because I only allow connections to my router from mac IDs that are on the list I create. In my case, I have my macbook pro and my PS3 system. If you don't know how to edit the MAC list in your router, do some research. It's pretty easy.
- Under TCP/IP: Select "Using DHCP" on the IPv4 drop box
- Select "Off" for IPV6 drop box
- Under DNS, after you connect at least once, you should see (grayed out) your router's IP address on the left box and the domain on the right side box.
Finally, under "Ethernet" you should see your Mac address there, the configure option should be set to Automatically and MTU as standard (1500).
Press OK and then press "Apply" and lock that screen by clicking on the padlock at the bottom left. BTW on the top of this screen Location should be "Automatic" - if not, select it and apply.
Done! Your wireless should connect quickly after the computer is turned on or waken up from sleep state. This assumes you configured your router correctly (mac addresses, frequencies, etc).
Good Luck to all who try this - at least I have not have any more dropped wireless connections.

Hard Drive Connection Issue on MacBook Pro

Hi,
A couple weeks ago my MacBook Pro was running and suddenly went into a non-stop pinwheel freeze. After waiting a few minutes I decided to do a manual shut down and when I attempted to reboot it, I just got a blank white screen that wouldn't go away and then a blinking question mark folder when I tried it again. Luckily I already had an external HardDrive Dock so I removed my Hard Drive, used the system startup Disc that came with the computer to redirect the start up disc, and I've been able to boot my MacBook from the Dock since then through a USB cable. So I have a temporary fix, but of course it requires a lot of set up, it's a slower connection, and is less convenient when I take my laptop from place to place.
What I want to do is replace the connection between the Hard Drive and I my MacBook but I want to make sure that I purchase the right part. My MacBook is two or three years old now but it runs fine (besides these issues) and is fast enough for all of my needs. My Macbook is a MacBookPro5,5 with an Intel Core 2. I believe it is a 15 inch model. I'd like to avoid taking this to the Apple Store if possible because I have a limited budget and this should be a pretty simple repair as long as I'm replacing the right part. Can anyone tell me what the probable part is that I need to replace?
Thanks,
Todd

SuperDuper is not compatible with Leopard, but CCC 3.0.x is.
Put the new drive in an enclosure and connect it to the computer. Prep the drive by partitioning and formatting with Disk Utility. Clone your existing system using either the Restore option of Disk Utility or CCC (CCC is a bit faster.) Test the clone to be sure it boots the computer. If all is well then replace the old drive with the new one and put the old drive in the enclosure.
Bear in mind that doing this yourself is not approved by Apple.

MX870 connection issues with MacBook Pro

Hi
I have a MacBook Pro on 10.8.5 and I cannot find or connect the MX870 printer wirelessly. It used to connect perfectly and now doesn't at all.
I have an iMac on 10.9.3 that runs the MX870 without issue.
Not sure how to resolve?
Thanks

Wireless Connection Dropping on MacBook Pro

Hello,
I have been running into an issue with my Macbook Pro dropping wireless connection to Alcatel Wireless access points. It happens when I disconnect AC power and run off of the battery. It usually drops the signal a few minutes after that. I have run all the updates and it still seems to be happening. We can tell when it drops because we are kicked off of a Filemaker remote database. Has anyone else run into this issue?
Thanks!

Please beware that Pacifist-based "fixes" like that advocated in the thread in question above have two notable downsides:
1) You will remove certain functional and security fixes from your system.
2) You may break future software updates as your system will be listed as having some software installed that no longer is installed.
I understand the frustration, but if you choose to "fix" your problem in this way, beware it is not without danger and may cause you future issues.

Wireless Router issues with MacBook Pro and Windows XP laptops

hello,
I have a d-link wireless router and I have a MacBook Pro and a Windows XP laptops. My issue is that I have to keep rebooting either the router or the modem (which I both replaced) and it still does not work right. Now can mac and windows work simultaneously through a wireless router (d-link) with no issues?

My problem is that every time I log off either computer, and when I start it back up up again I have to reconfigure all over again for both laptops to get connected to the internet. I called the d-link people and they pretty much said if i still had problem to go their web sites and download their firmware (which I have that version) so I am running out of options because I just can't turn either of them on with out reconfiguring it. Now I am using WPA on them. Could that be the issue? But right now I do not know. This is my first mac and I am getting a little irritated by this. Overall I like the mac except for this little issue. Does that help?

Verizon Fios Wireless Compatibility Issues with MacBook Pro

Good afternoon,
We have Verizon Fios as our internet provider. We both have PCs that are connected to the router and my husband has a laptop that connects both via an ethernet cable and wirelessly. We do not have any problems connecting our PCs and the laptop to the Verizon Fios service.
In December of 2007, I purchased a MacBook Pro. For several months, my ability to connect wirelessly with my MacBook Pro was great. However, beginning around March of 2008, my wireless connection began to become sporadic. Now, my ability to connect wirelessly to Fios varies based upon where I am in our home. When in the same room as the router or in the room above the router, my connection is great. I have no issues. In all other rooms, I either cannot connect wirelessly or the connection is sporadic at best.
I have spoken with Apple Customer Service and Verizon Fios Customer Service on numerous occasions. My last discussion resulted in the service representative telling me that there are inherent problems with connecting Fios and Apple and I would either have to switch to all Fios components or all Apple components. As long as I have both components connected to each other, I will continue to experience problems.
Per Verizon, we upgraded our firmware and changed our security settings. These changes did not help. Per an Apple sales clerk, I purchased an Airport Express Base Station. When I arrived home and called customer service to help me connect it, I was told that it would not help my situation.
Please tell me there are other options. The whole point of having a laptop is so I'm not restricted to one location.
Thank you,

I am having the same problem, although we have been experiencing the problem with a Windows machine as well. Sporadic internet is very frustrating! Right now it's working fine two stories above the router on my MBP, but I'm constantly checking the airport meter to see if I've lost my connection. 20 minutes ago I had nothing. It does seem to work consistently if I'm in the room next to the router. Hopefully Verizon comes up with a solution.
You wouldn't happen to be having Kernel Panics when waking your MBP from sleep, too, would you?

Wireless network Issue on MacBook Pro Duo (original) with Snow Leopard

Hello all,
I have searched the forums and tried many solutions to no avail. I have the original Macbook Pro 2.16 Core Duo running 10.6.6. Here is the problem:
When I am at home, I have moderate trouble with my wireless. My signal/noise is 78 dPm/94 dPm. However, when I am at school my computer cannot even crawl on the internet unless it is in between classes when the network activity is low.
My school is a small grad school of only about 250 people, and 80% of the people in my class have newer Apples. No other person seems to be experiencing my problem. I can watch the people beside me surfing away on newer MacBooks while my connection times out almost every time.
It seems that everyone's connections drown my connection out. However, nobody else is experiencing my problem. It is if I am the last kid in the lunch line and nothing is left for me.
If there is any more information I need to provide, please do not hesitate to ask. Any help will be greatly appreciated! Thanks!

"when I am at school my computer cannot even crawl on the internet unless it is in between classes when the network activity is low."
Make sure you are on the correct network if you have not already done so.
Repair permissions and restart your computer. If your computer has been in "sleep" mode for a few days, restart it. You really should restart your computer at least _"once a day"_ to refresh it.
"I have attempted to use the Airport Utility, *however, it detects nothing* and will not let me manually configure anything."
Is the light green on the router you are using? Apple has several Airport routers. Which one do you have?
After doing 1 through 5, did you restart your computer afterwards?
