Intel Mac :: Cannot Connect To Internect On It Even Though Wifi Is Full Strength
Jun 7, 2012
Mac won't connect to internet even though wifi is connected. Message "network configuration has changed". I click on assist and the end result is that the wifi disconnects and I get the same message. Other devices connect to the wifi like my itouch and husbands laptop that runs windows. What do I need to do to get this to run? Previous times when this happened I was able to go through the diagnostic steps to reconnect and wifi would connect to internet not anymore.

I have the 13" Macbook Pro mid 2012 model and for some reason the wifi status bar would show full strength however when I open up Chrome or Safari the webpages won't load at all. I'll get a message saying something like "can't connect to Internet." I first thought it was my modem but all the lights are lit up and it shows I do have an Internet connection. I get the same problem with my ipod touch 4g as well. Only on the ipod's side it will try and connect but fails to do so at all. So I have two devices that fail to connect despite an existing Internet connection.

I've recently converted to mac and replaced my 8 month old Vaio AR11s with a new white macbook(2.16ghz). Recently I am having all sorts of problems with the wireless. I've been reading this forum for a week of so now and realize that I am not alone with my WiFi woes. My problem is the fact that my wireless intermittently drops and although the signal strength is still showing full I have no internet connection until i turn off and on the airport card.. this happens on both psu and battery!
I have tried installing the 2007-004 update, deleting the airport.plist file and the 2007-002 update and it appears to fix the fault for a while but then it comes back. I' ve also messed with enable/disabling frame bursting,different channels on my netgear wnr834n router but my other mac(using ethernet, bought a 24" imac tuesday!) and wifes vista laptop (wifi 802.11g) are fine so I have ruled out the router.

Does anyone know how accurate the 2010 macbook pro wifi signal strength monitor is? There are times I have full bars but my internet is really slow, or stops working all together for a few minutes. I THINK, because I'm on a different floor than the router, which would explain reduced signal. BUT my computer says I have full bars.

I am on a macbook. My wireless was pretty decent during winter break but when I come back for spring break, it is ridiculously slow. The signal strength is completely full, but its almost dial up slow. my wireless on my iphone is blazing.

I have a I mac and an airport. I've been having problems lately(one month) every time I try to connect to the net. it says there is no connection. if I refresh, it works. the reception icon was showing full (4 bars). 3 days ago, no reception, o bars, today, I got it back. i am about 50 feet away, around a corner outer house wall. nothing has changed in terms of new or moved electronic equipment. I even turned off my 5.0 ghz phone.
any thought on how to fix this?

So I've got an odd problem, here's the scenario: 27" iMac 2.8GHz Quad Core running OS X 10.7.1, and a netgear router (connected to a Comcast modem).It sees the network, connects then drops the network. However, a MacBook Air running 10.6.8, an iPad, and a Sony Viao running Windows 7 can connect and stay connected to the network fine.This made me think that something with the iMac's WiFi card is broken so we brought it to work and connected it to our network (802.11x, WPA2 Enterprise, Cisco routers) and it worked perfectly. He brought it back home, still couldn't connect to his network.We brought it to the campus Apple store and they replaced the airport card and it seemed to resolve the problem for a bit, but now the issue has come back.Yesterday we did a full time machine back up, wiped the hard drive and did a full OS X Lion re-install and restored from the Time Machine back up, ran all of the Apple software updates and it connected to the WiFi here at work fine.Brought it home, still won't connect to his network. This would make me think that it's an issue with his home network but all the other devices are working fine.We had a Comcast technician look at the network and they found nothing wrong.

I have an older (white) iMac that connects wirelessly to my Linksys router. I bought a new iMac and I am unable to connect both iMacs wirelessly at the same time. I was wondering if the issue had to do with using the same Apple ID's, but I don't think that is the case. It seems like the old iMac is connected to the router, the new one wont connect and vise versa.

I've seen this question asked before, but it was all related to people who are running lion. I have 10.5.8, which I believe is leopard. Whenever I try to connect to airport, I get my network from the list, enter the password then I get a connection timeout after about 15 seconds. We have had this problem for a while now. We just got a new router this week and I'm still have this problem.

Our iMac running OS X 10.5.8 has several problems, some of which may be related.Â
1. The hard disk is close to full. I am not sure this is the root problem. I would like to either find junk files that I can delete (sort of like disk cleanup in Windows) or copy some old, but possibly still useful, files to a CD or an external hard drive, but I have not been able to do so.Â
2. I cannot connect via WiFi to my home LAN. If I try to connect, I get an "invalid password" error message, even though I am using the same password that other devices are using to connect successfully.Â
3. I cannot open iTunes because an unknown error occurs (13014). Â
The problems started when we tried syncing an iPad and the process would not stop. Then there was a temporary power outage. Â
We have also recently tried adding a Time Capsule to our home network. I am not sure that it is configured properly. I want to continue to use our older router for WiFi but use the Time Capsule for backing up Macs.Â

I have a pretty old Titanium Mac Book that runs OS 10.3.9. It's a moderately slow machine, but still works- and although I realize that it won't be able to stream video or anything, I figure it would work for email, and basic web browsing- But I'm wondering if it's going to be compatible with any new products such as a USB wifi antenna - because the room where I want to use it won't alow for an ethernet connection-  Also, will the old 10.3.9 OS allow me to connect wifi to the newer airport extreme base stations?Â

I don't know what's wrong with it.My ipod touch connects just fine and yet when i try to connect my new macbook it won't allow me to connect.I've never owned a macbook - so i have no idea how to fix this.
I currently have the network setup assistant running and configuring - but it's been about an hour and it hasn't done anything.Is there something else i need to do?

It is on my home network which I have been using for months. I have made no changes to my router or network setting. Other devices will still connect to the wifi with no problem and I connect through the ethernet connection with no problem. I have disabled the wifi and restarted my computer with no luck.

I have done some searches, but from the nature of my internet I hope you can understand if this question is a repeat, if so please point me in the right direction. I am using a August 2007 black macbook with airport extreme using 10.4.11 I am using a neighbors wireless network that is WPA. I live in Senegal and my computer is American, and I have heard that this might cause problems because of hardware. But the wifi connection works, it just bounces from full bars to no bars, spends a lot of time at 1 bar, and then when the connection drops and I try to rejoin the network, it says that there was an error. Sometimes, the network won't even show up. After long stretches of time trying to rejoin the network only to find an error, it will suddenly work. I have tried using interference robustness and relocating my computer. The router is just one floor above me, and when it was being installed (before they applied the pw) I had full bars. I think this is a mac problem because my host sister's PC does not seem to be experiencing problems. Also, due to the nature of the wifi (it belongs to my moroccan neighbors).

all threads are outdated from 2006 and 2007 as far as I looked, or has a different issue. My macbook is a 2009 model running 10.6.4, using a linksys router, signal will drop for no reason. The bars are full, but nothing will connect. NO messenger, web browser, or downloading software will work, like its dead. This usually happens if I keep my computer on over night for huge downloads (1GB+).To fix this, I just have to click on the airport icon on the top right corner of my screen, choose disconnect, wait 3 seconds, then choose reconnect and it will work again.

I have had my 15" i7 MBP for around a week now, and a handful of times (3 times last night) it just decided it doesnt want to connect to the internet.The WiFi Signal still says its connected full, and other laptops don't have an issue (not even my old 13" MacBook).I have tried changing the DNS to OpenDns and to Google's DNS but with no luck. The problem is intermittent, and it will be fine for a day, then it will just decide it doesn't want to work.

I'm back at my dad's place for the summer and I'm trying to connect to his house's wireless connection on my MacBook. It seems to connect okay when I type in our 10-digit password next to "WEP 40/128-bit hex" in the drop-down menu, but then even with full signal bars, it loads browser pages very slowly if ever, usually just giving me a timeout error and it's the same thing across all programs, my instant messenger takes forever to connect, WoW takes forever to connect, if ever, basically the internet I get from this connection is useless. It's odd because both my sisters have MacBooks and the internet works fine for them at my dad's house when they connect, and MY internet on my computer works perfectly when I'm using any WiFi but this one. By the way, the transmitter is a "D-Link 514 2.4GHz Wireless Router" and we're connected to cable internet.
Update:
* I have tried resetting the router and that didn't help.
* I have tried changing the channel, authentication method and password and that didn't help.
* I tried a DNS troubleshooting guide and it doesn't appear to be a problem with that.

I have a macbook pro 15" retina. I am a photographer and have to upload images at the end of every day. I noticed that the internet speed was flucuating a lot. From like 3 mbps to 30 mbps. I thought it was the internet service at first, but then noticed if I turned off the wifi on my macbook, then turned it back on, I would get a full strong signal. It would then start to slow down again to a crawl. Is it the macbook or maybe a Apple Express Airport update?Â

I am writing this from a Panera Bread, as my school's internet won't work on my MacBook since a fresh install of SL.There isn't much to say, except I cleared out all my old Airport profiles, and my old networks. My school will let me connect for about 5 minutes, then it kicks me off (I see the exclamation point over the Airport icon in the menubar). I checked a friends MB without SL, and she is connecting no problem.My school's network was never protected according to Airport (never saw the padlock), but whenever I would go to connect it would ask for my username and password.
