IMac/Macbook Pro WiFi connectivity weak.. iPad1 good

Hi, I'm having very spotty connection problems, stalling, pages not loading, working for a few min then stalling again on my imac and macbook pros (2011) models. But the iPad 1 is rock solid connecion. What can I do to get my computers to have as good as a connection?
Thanks

Hello Passenger57,
First update your User Profile if you are no longer at 10.6.5 of Snow Leopard.
Wireless Improvements
Move the Base Station If interference is particularly bad in one part of your house or office, move the base station to another location. But this can be tricky if your AirPort base station has to connect to the broadband feed coming into the house and that feed happens to enter at a particularly interference-prone spot.
Use the 5GHz Band Compared with the 2.4GHz band, the 5GHz band is practically empty. The newest AirPort Extreme Base Station is one of the few Wi-Fi base stations designed for home use that work in that 5GHz band. All of Apple’s Core 2 Duo laptops and iMacs (except the discontinued 17-inch 1.87GHz model) can also use the 5GHz band; with the build-to-order wireless option, so can the Mac Pro.
To switch to the 5GHz band, launch AirPort Utility, select your base station, and switch to Manual Setup. Click on the AirPort button and select the Wireless tab. Select 802.11n Only (5 GHz) from the Radio Mode pop-up menu. Click on the Wireless Options button and select Use Wide Channels. Click on Update to restart the base station.
Currently, no Mac-compatible adapters enable you to use the 5GHz band in older Macs or with older versions of OS X.
Also by unchecking the "Ask to Join Networks" box and deleting any networks you don't use from your Preferred Networks panel and moving your network to the top of the list by dragging it there may help.

Macbook Pro WIFI connection slow and intermittent

I recently moved to a new apartment and had Time Warner install our internet/Wifi. My Macbook Pro will connect to the Wifi and work fine for about 30-60 seconds and then become extremely slow, even to the point of no connection most times. I have tried using both the new router and the old router that worked just fine at our old apartment but both behave the same way. I have reset the routers multiple times but that does not fix the situation and I do not believe the router is the problem since my two roommates (one of which uses a Macbook Pro) have no connection problem. My iPhone connects perfectly fine as well. When I am on other Wifi addresses, my Macbook works just fine. Also, my Macbook is only one month old. I called Apple to try and solve the problem and they believe it is an interference problem however the connection remains the same no matter how close or far from the router I am and all other devices don't seem to have interference problems. Any help is very much appreciated!

Might be corrupted network preferences ..
Type or copy paste the following:
/Library/Preferences/SystemConfiguration
Click Go then move all the files in the SystemConfiguration folder to the Trash.
See if that makes a difference.
Your Mac will generate a new SystemConfiguration folder for you.

Late 2013 15" Retina Macbook Pro - wifi connection timeout with one router

Hi,
I've recently purchased a new Macbook Pro retina 15 inch late 2013 model. Everything is fine at home, but at work I cannot connect to one wireless router (Netgear WAG102). The computer tries to connect but I get a connection timeout error after a few seconds for every attempt.
I have tried every suggestion for wifi issues that I can find on the forums, and have reset the router.
A colleague has also recently purchased the same computer except 13 inch model - he has exactly the same problem.
Any suggestions? I suspect given that two of us have the same problem that there is an incompatibility with the MBP and this particular router. I notice that there are quite a few discussions about similar issues with the macbook pro.

I too have a MBP Retina, 15", late 2013, and am having wifi connection issues. I've tried several fixes suggested on these discussions and by Apple. Nothing corrects the problem. I've been told it's my router, but I find that difficult to believe give that my wife has a MBP 13" 2012 (non retina), that has no issues at all, nor do our iPhones. It's just my MBP Retina.
My issue seems to be when waking from sleep, I lose the wifi connection. I have to turn wifi of then on again, and it reconnects. The only thing that corrects the problem for me is when I disable bluetooth. I have the magic mouse and it's basically useless becuase I need bluetooth on for it to work.
I find this to be an annoying problem. This is my first MacBook, and I really like it, but this wifi thing is bad. Never had this problem with my Windows machines.

Macbook Pro WiFi connectivity issues

Hi there - planning on contacting Apple directly tomorrow but thought I'd put this question to the community before I run up my phone bill!
For the past few days I've seen my WiFi connectivity go severely downhill, I've had my new Macbook Pro 2012 (non-retina) for a little less than a week, and I haven't had a problem with my internet since a few days ago.
This is DEFINITELY an issue with my computer. I have other computers and an iPhone which work perfectly well with the same network - in fact, my girlfriend was next to me running on her laptop for 20 minutes whilst I sat there pulling my hair out to the messages of "You are not connected to the Internet" and "Network timeout".
The computer was originally installed with OS X Lion, but I updated to Mountain Lion after 2-3 days. (Perhaps it's a problem with this? Is this an ongoing thing with the range or the OS?). I have tried reinstalling the OS X, a frustrating ordeal as I actually needed an internet connection to do this! This, however, doesn't seem to have done too much...
I've tried deleting all information about my network (in the advanced wifi tab, and in Keychain), and also tried entering the wrong password in when manually adding the network, I'd heard that works yet clearly not!...
I feel like I'm using a mobile phone with bad signal when I have to hold the pc in the air as if i'm looking for that "sweet spot" (strangely enough this usually works for a minute)
Any ideas? I feel like I've exhausted all means, I'm at the end of my tether!

I have been having the same problem. When my MacBook Pro running 10.9.1 (Mavericks) wakes up from sleep, whether from shutting the lid or inactivity, the Wi-Fi seaches for a network, but won't reconnect to my known home Wi-Fi network. When I try to select my network from the menu at the top-right of the screen, I get an error message after about 10 seconds saying that the network is unavailable. If I turn off Wi-Fi and turn it back on twice, I can then reconnect to my home Wi-Fi network. This is a very annoying problem. Please fix it in 10.9.2.

Problems with Macbook pro Wifi connection

I purchased a new Macbook Pro 13.3 - and am having problems with disrupted connection of my Wifi - I experienced the issues after I deauthorized all of my computers (because I was at my limit). when I reauthorized my new Macbook, I keep getting kicked off the Wifi (all other computers,ipods, iphones in teh house have no issues with wifi connection). Is there something that I need to re-establish so that the wifi doesn't keep turning off?

Try deleting the wifi connection in System Preferences, then recreating it.

MacBook Pro wifi connected but won't load Internet

I've connected my MacBook Pro to my local wifi connection and it tells me that it is connected, but I can't run anything on it that needs an Internet connection (eg. Google Chrome, Skype etc.)
I've ran the 'Assist Me' checks in the Network Preferences and results have found the wifi connection to be positive..
I am so confused by this!! Somebody please help?!

First contact your ISP. You need to confirm that the issue is not on their end.
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.
System Preferences/Internet & Network/Network
Unlock the padlock
Locations: Automatic
Highlight Airport
Click the Assist Me button
In the popup window click the Diagnostic button.
System Preferences/Network- Unlock padlock. Highlight Airport. Network Name-select your name. Click on the Advanced button. Airport/Preferred Networks-delete all that is not your network.
Place a check mark next to "Remember networks this computer has joined." Click the OK button and lock the padlock. Restart your computer.

New retina MacBook Pro - WiFi connectivity problems

Dear all,
I've recently purchased the new Haswell 13" retina MBP, and I'm having exactly the same WiFi connectivity problems the 2013 Airs had. I have a solid connection for a short time, and at irregular intervals it just drops out. All of my other devices are still connected and have no problems. I've tried with two different routers/modems, but the problem persists.
Is this a known problem - with hopefully a software fix in the forseeable future, or do I need to return the MacBook?
Many thanks in advance for your help,
Nic

I haven't got a Retina, but I do have the same wifi problem. And if you've looked at these forums, you'll see it's been going on for years and no one seems to have a handle on what the issue is. All I can say is if I were in your place I'd take it back and exchange it. You have the chance now, so take it.

New Macbook Pro Wifi connection issues

I just bought a new Macbook Pro. When I try to connect to my wireless router I get a "Connection Timed out" message. It won't connect. In order to connect I have to go to Network Preferences and Select "Diagnostic". After following the steps I can type in my password. It says the password is "invalid" though I know it is correct and then it connects anyway.! I must go through this process everytime to log on. Very annoying. Any solutions?

After taking it in to the tech department, I gave up on them and opened it myself. Re-seated the connection from the Superdrive to the main board, and it works fine.

Macbook Pro WiFi connectivity issues since updating to Mavericks

I upgraded to the Mavericks OSX 10.9.1 and started seeing WiFi issues. The issues seem to happen when I have to wake up the system after closing the lid. I have an Airport Extreme router

Strange macbook pro wifi problems - selective wifi disconnection

I have 3 macbook pros, two iphones and an apple TV. My primary macbook pro has some very unusual wifi problems that are hard to pin down. It frequently disconnects and reconnects itself to the internet constantly throughout the day. I've been testing it in various ways and today I noticed the strangest anomaly by far.
While working today, my primary macbook pro could not connect to the internet through any of the 3 browsers I use. Airport Utility said the internet was down (internet icon was amber, airport icon was green). However during this disconnection, my p2p application (Soulseek) experienced no disruption of service and continued to download files. I opened my second macbook pro and strangely enough, the 2nd mac was able to connect to the internet through browsers without issue, and the airport utility on the 2nd macbook pro said the internet was connected. My Apple TV was connected too as well as my iPhone.
It is often difficult for me to troubleshoot network problems because there are so many variables (ISP, airport assembly, airport base station, OSX, airport utility, modem) but I guess in this particular instance, it seems clear that the problem has something to do with my macbook pro.
My primary macbook has always had wifi problems (and honestly, my last macbook--the one that actually worked today!--had similar issues back when it was my primary laptop). Last week, my primary macbook pro had the topcase, display and logic board replaced by Apple. When it came back, it had the same wifi connectivity issues it always had. Often, a restart will be a very temporary fix, but not always.
I am at a complete loss for what could be causing these lapses in service. In fact, right now as I was trying to access these forums, I could not even get my primary macbook to open the Apple Support Site on any browser. Every other website would open, except Apple Support. I opened my 2nd laptop and it opened Apple Support just fine. After 15 minutes, my primary laptop finally opened up an Apple support page in Firefox.
It is really hard to diagnose the problem. I find that Airport Utility has been so pared down and streamlined to the point that it is worthless. It is basically a blank window with 2 application logos inside. It looks very simple and user friendly until it has a problem, and then it tells me to do something very technical without an explanation for the layman (such as assigning DNS servers or putting the airport in Bridge mode). I always follow Airport Utility's advice, but I still have odd problems. I am often confused as to whether I should use Airport Utility or the Network button in System Preferences. They have the same options, but they're arranged under tabs with different titles.
Anyway, does anyone recognize these macbook pro wifi connectivity problems? Constant wifi disconnection on one machine (while all others experience no connection problems) coupled with instances of selective disconnection (like browsers not connecting while p2p is able to connect or browser connecting to some sites but not all?)
Thanks for any help or guidance

Same exact issue here. It happened once when I updated to Mavericks 10.9.2. It just happened again last night and I can't seem to fix it.
I tried all sorts of things like deleting the SystemConfiguration folder, PRAM, SMC, DNS flush, etc. Nothing helped. As I recall, the last time it happened it mysteriously fixed itself after a day or two.
Very weird problem. I have been troubleshooting computers my whole life but this one is tough to figure out. Other machines in the house connect up just fine.

My Macbook Pro keeps connecting to the wrong wifi. How do I stop it from doing this?

Select the wi-fi tab in the menu bar then select "Open Network Preferences..." Select the "Advanced" button, then select the network that it is interfering with your MBP, then hit the - button and it will "forget" that network. Hope that fixes your problem, good luck.

Can you open a terminal and invoke the following commands:

and

Hello, my sister her macbook pro cannot connect to our wireless internet. My imac however can, so the problem has to do with her laptop. We were wondering how we could solve this problem? Thank you very much in advance!

We did that, but it just doesn't seem to be able to connect. So basically we tried to connect to our network and insert the password, but afterwards it does nothing. Weird thing is also that the network symbol (top right of the screen) says that it has been connected, but when I go look at the system preferences --> network, it states that it has not been connected

My macbook pro is connected to wifi but it will not connect to the internet.

My macbook pro is connected to wifi but it will not connect to the internet. When I go on safari, it says that "Safari can't verify the identity of the website". Then I tried to update flashplayer but you need the internet to update it. All this only started happening after that Moutain Lion software was downloaded onto the laptop. Please help, I have been internet-less for a couple months now.

Hi rynhelp,
If you are not able to connect to the internet after installing Mountain Lion, see this article for information on how to start troubleshooting:
