IMac :: Won't Work With Wifi Signal Strength / No Connection
Sep 12, 2010
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?

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'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.

I am having random slowdowns on my connection speed using Airport (nothing to do with the notorious performance issues which I also suffer).
My appleTV and my HP 2140 get 90% (it's right by the router) and 80% (floating around the same floor of the house) signal strength respectively, download speed and throughput seems very stable on both, however on the iMac (that's about 10 feet away from the router) the signal strength is 28% ! this is incredibly low and even though it does not always hurt download speed it does hurt the total throughput when sharing files over the network. Also the SNR (signal to noise ratio) is incredibly low, below 30 all the time.

I am having internet connection issues with my MacBook Pro 2011 - running the latest version of Lion OSX. My connection cuts out regularly (every 10 - 15 minutes) despite having a full wifi signal. It is happening on two different routers, in two different locations with two different ISP's.Â
When I run Network Diagnostics ISP is the test that fails, but after a couple of seconds diagnostics fixes it until the next 10 - 15 minutes. The only other alternative is turning wifi off and on. Both of these only last for the 10 - 15 minutes before it cuts out again.Â
It is very frustrating and research online seems to indicate it is a Lion issue. I have made an appointment with a genius, but browsing online it appears there is no solution. It is not acceptable.

MacBook Pro, Mac OS X (10.7.3)

I recently got FIOS and I love it. My router is in my basement because I wanted to hardwire it into my ps3 and 360. Regardless, the WiFi signal is great throughout my house. For some reason, my Macbook keeps grabbing my neighbors unprotected WiFi signal. I guess on the 2nd floor of my house, his signal is stronger than mine.
It takes 2 seconds to switch it back, but it seems to grab it whenever I wake it from sleep and at other random times. I was thinking of telling my neighbor that he needs to protect his signal, but even if I dont, I want a way to prevent my mac from locking onto the wrong signal.
Running Snow Leopard.

Is there a program where I can see the signal strength on my mac? I just want to know if it can be done without a third party program.

I just upgraded from 10.4 to 10.5 and my Airport meter is now reading 2 bars instead of 5. Same router, same position, different OSX only.

I have a time capsule hooked up to my mac mini. I don't use it for anything but the hard drive anymore so it is just plugged into the LAN connection. My Mac Mini is getting horrible wifi signal but my MacBook Pro is getting great signal in the same room. I was wondering if the Time Capsule can be used to receive the wifi and run it to my Mac Mini threw the LAN connection? Or can the Time Capsule be used as a repeater and boost the wifi signal?

My TimeCapsule drops the WiFi signal every 10 minutes or so for about 10 seconds; the light is blinking yellow during that time, and then it comes back to everything ok.
The TC is in Bridge Mode behind my router. I can connect to the internet via the router all the time - no connection lags there, it's just the TimeCapsule that stops the connection. No entries in it's logs, though.
I'm running 10.6.2, and the TimeCapsule is on 7.4.2 (same issue on 7.3.2 and 7.4.1).
As it is, it basically kills iChat and Skype on top of it's impact on web browsing and the like.

So this is my network set up:
A) Cable Modem connected to ethernet cord to new Airport Extreme Base Station.
B) Three Airport Expresses located around my house set on extending the network.
The airport extreme station is in the master bedroom and the room I am in is approx. 15-25ft away (thru a wall of course). I ran iStumbler and am getting ~42% signal and 23% noise from the main airport extreme. I am getting about 49% from one airport express with ~15% noise, ~42%/17%, and ~45%/15% from the last. Sometimes they can drop as low as 35% signal... This is not prime. Now, I do get better signal during the day, so other networks could be interfering.
I have checked local networks and their respective channels, and moved mine to an all time random number of 3. The other networks are mainly on channels 6, 8, and 11. Before I moved my network to 3, it was on channel 11. I get the same signal/noise before and after the channel move. Finally, to finish off the description... This current computer is located on the third floor. The main airport extreme is located on the third floor as well, with a relay airport express right outside the door of the master bedroom. It relays to the other 2 airport expresses. (it is also a regular airport express). Currently, all Airports are set at a Multicast rate of 2mbps.

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.

With my MacBook Pro sitting on the desk right next to my Airport Extreme Base Station, I get, according to iStumbler, a varying signal strength between 50 and 75%. I see the same with my wife's MacBook. I also have an Airport Express in another room set to "Extend a network" and I see about the same there. Shouldn't the signal strength be higher?

I have a MacBook, with OSX 10.4.11. It uses an AirPort Extreme (0x168C, 0x86) and it connects to a Linksys router which is attached to my cable modem in the basement. Approx. 4 days ago I started noticing that the signal strength would vary, and then drop off all together. I have reconfigured my router, downloaded the new firmware for it, and been online chatting with Linksys techs all day. We have had no problems for months with this router, or with signal strength. My wife brought her MacBookPro home this evening to see if her machine would connect to our wireless network. Fired it up and no problem. Her machine, using the same airport card in it, had no problem with signal strength.

My IMac is "scanning" for wifi signal while IPad finds signal @same location. How can I tell if hardware is bad or system set up wrongly?

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 a one year old Netgear wifi router that I use at home (two MacBooks and two iPhones connect to it).. Since Monday I have been battling with the the router via wifi (it works perfectly if I connect via cable). My macs or iPhones keep getting disconnected from the router, and when I try to reconnect it's a 10 minute hassle as it keeps timing out or stating the password is incorrect, when in fact it's not. When I do eventually reconnect via wifi it lasts only a short while before it disconnects again. And whenever I restart a computer from standby it won't automatically join the network and then I have to go through the whole timeout/incorrect password episode again. Also, before disconnecting it's sometimes incredibly slow. Even to connect to router's setup page takes five minutes load the page.
I've reset the modem, resetup my devices, chnages passwords, and still I get the same problem.

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 have 3 macs working off my wireless router. Two out of three are still working fine, but the third (an iMac G5) keeps losing its network connection and either won't find the network or, if it does, will not allow me to rejoin it, even after entering the relevant key/password. It has been in the same location in my house and has worked fine for the last five years. But oddly, if I move the G5 to within a few feet of the router it starts working again (though sometimes seems unable to find the network, although when it does it will let me join it, hassle free).Â
Have spoken to some Apple guys and, following their advice, have gone into SYSTEM PREFERENCES, NETWORK, LOCATION but having got that far a pop-up appears telling me that an application has changed my network settings. Zapping OK, this dialog box just keeps re-appearing and the only way I can get out of this corner is by 'force quit'. Â

I got my Kindle 3 today (yes I bought one over the ipad simply due to the price) and Ive spent some time trying to connect it to my imacs airport wi-fi. I have tried Customer service over at Amazon but sadly, no reply as of yet. It seems that the Kindle wont connect to "enterprise or peer-to-peer networks". So everytime, I enable sharing and my network shows up - it either wont accept the password or it tells me that "Kindle does not currently connect to enterprise or peer-to-peer networks"

On startup the WiFi connection symbol initially is full and black and then goes grey with in a few seconds. If I click the WiFi symbol the drop down menu shows my WiFi network which I click put in WEP code but then I get a message after a few seconds that the connection has timed out. All other Macs in the house connect to the WiFi fine.

My Linksys WRT610N with the latest firmware worked fantastically on multiple Windows 7-based ThinkPad. However, three (3) different iMac's have had the very same problem of dropping the connection and of my having to powercycle both my cable modem and the W610 router for it to work again at all! Once it drops the active connection, that's it. I have tried a few different settings and nothing has made a difference.
Can you maybe help point me in the right direction or should I just ditch it for an AirPort Extreme or Time Capsule? One additional point: It works worst in the 5GHz frequency band, even though there are none in my neighborhood, and if there are, they have their SSID's (network name) hidden. The 2.4GHz band is extremely crowded where I am which makes it difficult to enjoy my WiFi connection.

Since installing Lion I lose my wireless internet connection frequently - only from the IMAC, not from the IPAD or Dell. I called support and after quite a lengthy "try this" session, I was told that this was a known problem. I can always get it back but sometimes have to unplug the router.

I have full Wifi signal and I'm using multiple device on my Wifi which are all stable except the iMAC. We had a power failure a couple of weeks ago and since then the iMac just won't stay on the network. I have to turn wifi of and then back on to get it to join and that mitt lat 10 minutes.
