Wifi connectivity timeout

Hi All,
I have mac book Air 2012 with following OS
OS X 10.8.2 (12C3006)
Recently My Wifi connection droped time to time at Office. But now i can not connect to Wifi at all.Its giving connection timeout issue most of the time. But my home wifi connection working fine.
Others can connect to wifi without any issue at Office. But they are using other Brands not Apple.
Please help me to solve this issue.

@semperfiguy: Do trial and error. Your functions are utilized as widgets. I have many home-made and borrowed functions and have no problem. First, test your settings with the default rc.lua and tell us if something is still wrong. Are all your modules up to date? Nvidia drivers/kernel? (Sorry but NOT everybody does this .
Also, what kind of machine/arch (32-bit/64-bit) are you running? I use 64 bit amd with 64 bit archlinux and an nvidia card.
Lastly, if it's not any trouble, try trial and error on widgets and notifications, using lua comments to comment your widgets out and keep adding them back. I suggest you change your volume hook for example. Your hooks load rather quickly. I would do Gmail notification every 5 minutes or so and my volume hook updates every 10 seconds but getVol is displayed as soon as I mouse over to change the volume. Instead, If you are using a tray, you can replace naughty notification with Noteo, highly recommended. I do not suggest checking gpu temp so often with nvidia-settings. Do you have powermizer and thermal monitor on in nvidia-settings?
Use lua style comments to comment all custom widgets out then gradually add them again, noticing any difference while we look over your rc.lua/functions.lua. Also, load the same background processes and try using a different WM to see if the same thing occurs. Hope to hear back. I don't see anything wrong in functions.lua.

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.

MBP wifi "connection timeout" issue

My 2010 macbook pro has trouble connecting to many wifi networks. It works fine connecting to my network at home, but any sort of public wifi or hotel or friend's network is likely to give it trouble.
I get the "connection timeout" issue, and I know that I'm not the only one, but I didn't manage to find anything that worked from scouring this forum. Just to delinate the issue: all my other devices (iPad, iPhone, other laptops) connect fine to wifi networks in exactly the same places. I managed to find a workaround by getting a cheap wifi dongle that connects fine in precisely the same places that the MBP's built-in antenna does not. Is there any way to fix this, or am I just stuck dongling it up?

Try going into Network Preferences > Wi-Fi > Advanced. Click the network you're trying to join and click the minus button. This forces your mac to forget any saved credentials associated with that network and it will try to make a fresh connection. You can also try Network Preferences > Assist me... > Diagnostics to give you some more troubleshooting suggestions. It will probably tell you to restart your router/modem which sometimes works but you're usually not allowed to do to this to a public wifi hotspot.
It's also possible that your AirPort Extreme card, which is the part your mac uses to connect to wifi, is failing. Since 2010's are no longer under warranty, you can look up the iFixit guides to see if you're feeling adventurous enough to replace it yourself (if it is replaceable).

WiFi Connection timeout error, but still connecting

Since upgrading to Lion I've been having a strange problem. When I connect to a new WiFi hotspot I've been getting an error message suggesting that I have failed to connect, but in reality I have been connected. This happened today at an Apple Store, an office, and when I returned home. It might be related to trying to connect right after waking the computer from sleep, but this never happened with Snow Leopard. Any ideas?

How far do you get in Network Diagnostics? Any difference if you disconnect all other wireless clients?
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Enter the name of your wireless network in the search box. You should have one or more "AirPort network password" items with that name. Make a note of the name and password, then delete all the items. Quit Keychain Access. Turn Wi-Fi off and then back on. Reconnect to the network.

Connection timeout on hotel wifi - only with MacBook8.1 (810.9) configd plug-in:8.1 (810.9)

I'm having a "Connection Timeout" issue while trying to connect to my hotel's WIFI.
I bought an ex-lease refurbished white MacBook (Build 12E55 - 2.4GHz, the last 2010 model I think) a couple of weeks ago. I bought it so I could use it while on vacation in Bali, Indonesia. I've got OS X 10..8.4 installed.
At home in Australia, this MacBook connected to my home WIFI with absolutely no issues at all.
Now that I'm in Bali, I'm surprised to find that every time I try to connect to the WIFI at the hotel (where I'm staying for a whole month), I get a "Connection Timeout" error. I'm surprised because my iPhone connects to the hotel WIFI with no problem at all, as does our two iPads and the Android phones that belong to other family members. It's only my MacBook that struggles, even though I get even better signal strength indicated on my MacBook compared to my other devices.
I can connect my MacBook to my iPhone hotspot fine, though I'd prefer to use the free hotel WIFI over my very small 3G data allowance.
So the problem isn't that my MacBook can't connect to any WIFI, because it did at home and it still can to my iPhone hotspot.
And the problem isn't with the router, because all other devices work flawlessly.
I've trawled many forums and articles trying to find a solution. Here's everything I've tried already, that I can remember. (Not in this order and not all at once.)
Rebooted MacBook (duh)
Sitting directly under the WIFI router. (It's not a signal strength issue.)
Set up new Network > Location. Deleted Ethernet and Bluetooth PAN so it's just WIFI in the list.
Renewed DHCP Lease countless times.
Tried manual TCP/IP variations. It doesn't help that I'm not sure what to put in the IPv4 Address field. I do know the Subnet Mask and Router IP from looking at my iPhone network info.
Tried using my MAC address as the DHCP Client ID. Also tried just using "1" or leaving it blank.
I don't know what an IPv6 is either.
Tried BootP and completely Manual setups but not really sure of the correct settings to try.
Tried using the DNS servers that I found on my iPhone network info for the hotel WIFI. (One of them is 8.8.8.8 which I think is Google's DNS thing?)
Tried checking Auto Proxy Discovery and Use Passive FTP Mode, since it was suggested as part of a solution in a forum thread.
Tried changing the MTU to a couple of other settings from an article I read. I think one was around 1453 and the other was 1494 or something close to that.
Tried resetting PRAM
Tried resetting SMC
Tried a variation on resetting SMC that involved pressing down the normal keys plus one extra, for 10 secs, since it worked for someone who was told to do that by an Apple Care person. (He didn't know why it worked and other forum posters thought it was supposed to have been a SMC reset.)
Checked the Network> Wi-Fi in System Information to see if the Channel is compatible. The router uses Channel 1 and my MacBook is capable of using Channel 1.
Checked my country profile. It's X1. I have no idea if that's good. All I know is that I'm in Indonesia not Australia and I'm having WIFI issues with this hotel network.
Checked the PHY Mode. Supported are 802.11 a/b/g/n. The hotel router uses 802.11n.
Made sure I was using WPA2 Personal.
Tried deleting all WIFI-related passwords in Keychain.
Tried deleting all Network-related preference files.
Tried removing all LaunchDaemons and LaunchAgents.
It's not a "lost WIFI connection when waking from sleep" issue but I tried turning off sleep anyway.
My husband even had the nerve to unplug the hotel router (small hotel, we're the only guests at the moment) for 10 minutes hoping it will reboot. But I don't know if that's the actual modem or just a WIFI repeater thing (sorry, can't remember the right terms). It didn't work anyway.
I've run out of options, other than just sucking it up and getting a big 3G data allowance since I'm here for a month.
If there is anything else I can try - perhaps working out how to set up my Network manually properly, please help me out. Here is everything in System Information that might help. I'll happily provide any other info.

Sorry. The topic title got mucked up when I tried to paste in my System Information. And I can't paste it in using my iPhone without it going haywire. I can provide any details you need.

A connection timeout occurred. I have been receiving this error when trying to connect to the open wifi connection at my university. My wifi works perfect when I am using it on my home network. I have tried all the suggestions in forums online no luck.

I am getting a connection timeout occurred message on my mid-2009 macbook pro I am running mountain lion 10.8.2 but problem occured before and after update. The message only happens when i attempt to connect to the wifi at my university. It works normal at my home. This error just started last semester out the blue. I have read many forums and non have helped ive reset my pram a few times, ive deleted all my networks including my home network out of my system preferences<network and all that extra stuff. if anyone has a clue please help me because one of my classes requires me to take in class test over the internet. Thanks for reading. If anyone can help PLEASE help ive been trying to fix for last few months.

From the menu bar, select
 ▹ System Preferences... ▹ Network
Click the Assist me button and select Assistant. Follow the prompts. You may get a warning that Wi-Fi is not available, that you're too far from the base station, or that you're using the wrong password.
Assuming that you've ruled out those possibilities, click the lock icon in the lower left corner of the preference pane and authenticate, if necessary. From the Location menu at the top of the window, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.

I'm trying to connect to my home wifi with my imac gh5. After I enter the password it says connection timeout or password incorrect. I know there's no issue with the connection but I don't know what else to do. Does anyone know how to fix this problem?

What is the make & model of your home Wi-Fi router that you are attempting to connect your G5 iMac to? Which exact model of iMac do you have?
What wireless security type is your router using: WEP, WPA, or WPA2? If you temporarily disable wireless security, can the iMac connect to it now?

Could not join "wifi network name". A connection timeout occurred.

Mac Pro running 10.7.5.
Whenever the computes wakes from sleep or logs in, it no longer automatically connects to my wifi network. When I manually select the network for from the Wi-Fi status in the menu bar, I get the following message: Could not join "wifi network name". A connection timeout occurred.
Even though I get that message the machine joins the network with no other problems. I am led to believe that is is on the Mac Pro as my Macbook and iPad/iPhone join the network with no issues.
I have tried deleting and restoring the preferred network, and remember networks is checked. I have also restored my airport express base station.
Any suggestions?

Connection timeout with Apple WiFi devices

Ok, here's the scenario.
The important thing to remember is that all was working well, as happy as 'larry the lamb'. Being that I was running Snow Leopard on my MacBook Pro 8,3 while accessing the internet through my iPhone 4 using it's Personal Hotspot feature (with iOS 4.2.5/4.2.6 running on the iPhone 4). Internet thethering worked beautifully between the MacBook Pro & iPhone4 and all was well. Some time before this I had used the Time Capsule's WiFi for internet access with NO problems (when I had dedicated broadband), but then switched to using mobile tethering (personal hotspot feature).
I then upgraded to OS X Lion 10.7 (11A511) the day it was released and did this over a friends fast internet connection using cable ethernet connection for quicker speed. While I was doing this, I also downloaded the latest iOS update for my iPhone 4 being iOS 4.3.4 (8K2).
Then the problems started.. I have not been able to connect to the iPhone's Personal Hotspot, nor the Time Capsule's WiFi and neither the Airport Express unit (that plugs straight into the power socket). All three devices say 'connection timeout'. Resetting them either physically (reset button) or through the Airport Utility using an ethernet link (in the case of time capsule and airport express) make no difference.
I wish I never updated the iPhone iOS and previously put of updating it for the previous few updates because the tethering worked so well on it, therefore I would want to downgrade it to iOS 4.2.5/4.2.6 again (need to locate and re-download those two versions and accuire instructions - if anyone could help, would be very appreciated?).
Now this is the strange thing:- Although I cannot connect to the Apple Time Capsule, Apple Airport Express and iPhone Personal Hotspot (getting the 'connection timeout' error all the time), I am however able to connect to a non-Apple device Vodaphone 3G WiFi point. The Vodaphone 3G device is a 3G USB mobile dongle that is plugged into it's own dedicated small WiFi base station.
I am at a loss as to what is going on here?

I can totally understand your frustration and it ***** that you are having to experience it. I do know that for me yesterday the Apple.com page was down all day. I could connect to any other website, but not the Apple.com website. However, that doesn't solve your issue.
I would advise you to break down your issue by each component and then work to solving them one at a time. I would first look into getting your machine connected to the internet first. If you have no way of getting it connected to the internet without using the other devices you mentioned at your home network, then go to a friends or to a place where you can test your machine's ability to stay connected to the internet through a different network. This will allow you to rule out the posibility that the issue is isolated to your machine/OS. If you find yourself still having connectivity issues, then work on solving them before introducing your other devices to the problem.
Once and if you solve the issue with your machine I would then start looking into your home network and the devices you are using (i.e. Time Capsule, Airport, etc.) and be sure to check to see if you have the latest updates for them: http://support.apple.com/downloads/#airport
For my own network, I use a modem (ARRIS) and router (Linksys E2000) and have had no issues with any of my machines (running Lion) or any of my other devices (i.e. iPhones, iPods, printers, etc.) connecting to my Wi-Fi network. I do however have family and friends that are using the same devices as you, but are not having any issues. However, none of them are using their iPhone's HotSpot and neither myself or anyone else has updated to iOS 4.3.5.
I truly wish I could be me more of help, but the truth of the matter is when dealing with networks that deal with many different devices there are just so many variables that can be at play in regards to the issue, that you truly just have to take it one step at a time until you isolate the source of the issue at hand.

Wifi via os 10.8.5: "A connection timeout occurred"

I've had the same internet connection for 5 years. Same wifi. Same password.
My previous mbp / os had no problems connecting and *staying* connected.
Now, with my 8-month-old MBP / OS10.8.5, I regularly get bounced off wifi and when I try to reconnect, I see my wifi in the networks list, but I get "a connection timeout occurred" fail.
Why? How can this be fixed?
Incidentally, my iPhones (4 and 5) over five years have *never* encountered this issue. They are on the exact same wifi / password / network as my MBP.

Some suggestions in this link, and the links within the article, that sometimes help users solve wifi problems:

Can't connect to my wifi it says ( a connection timeout occurred) !!

Can't connect to my wifi it says ( a connection timeout occurred) !!

Sometimes, but not all the time, network colision does happen. That may cause your "connection timed out" message. It may also be caused by having too many devices hooked up and you are getting an ip address that's already being used.
If you know how to configure your netgear router, try to get into it's settings and see how many devices are actually hooked up and start taking some off that aren't being used.
Also, go to the wireless section of your router and see what channel it's on. Usually defaults at channel 7. Try changing that channel until you get a good connection with your MB.

I have lost my wifi network. Get connection timeout message???

I suddenly lost my Airport wifi in my house. I get a "connection timeout" message. I am able to use my ATT Uverse modem and had a second network going with my apple airport extreme and airport express. Suddenly that network is gone. I have reset all the modems and the aiport express shows up in the airport utility although on the ATT network. Any help???

Probably restarting your router by removing power to it for 30 seconds would have solved your problem.

My computer keeps getting kicked off wifi and says there is a connection timeout.

My computer keeps getting kicked off the wifi- it's not s problem with the wifi because all my other wireless products are working just fine. What could the problem be? It will connect for about 5 seconds and then says the there is a connection timeout.

Delete the Wi-Fi connection in the Network preference pane, then recreate it with the same settings. Any difference?
