Q: MacBook Pro constantly losing wireless connectivity

That sounds like an interesting suggesting - haave unticked the box so fingers crossed!

Thanks for posting that

Did everyone try deleting all "login items" from your account and rebooting?  After months of dropped connections and months of trying all the suggestions other forum members had made, I found this solution and haven't had a dropped connection for over 24 hours

I finally bit the bullet and replaced my crap router ... all issues solved. The thing kept rebooting itself. Good luck yall !

GregApp.  IT WORKED!  REMOVING THAT CHECK MARK SEEMS TO HAVE DONE IT. 

I cannot believe how good my internet surfing is now.  It's been good for a day now including transferring files within my home network. 

Mine is so far so good too, good work GregApp!

i too am absolutely sick of the constant wifi dropout. my PC laptops never drop out.  A friend is convinced it's to to with the aluminium unibody shell of the pros.  apple really need to sort this out - even recalling laptops - as right now i have very expensive "ornament" as most of the tasks i do are internet based. even installing updates is a pain as i have to go to my son's bedroom where the router is and install a network cable to do these.

Thanks for your suggestion Gregapp, it seems to have done the trick for me. What amazes me however is that this only applies to my 17" '07 MBP, not an older 15" model, not my wife's Air nor my MacPro at work. All are running OSX 10.7.2 and I've never had a similar problem before. Not that I really care, now that you've found the solution !

Your suggestion is correct. I was just on the phone with Expess Lane to try to eliminate my wife's frustration with her MacBook Pro connecting to the community wi-fi instead of the router across the room from her. Apparently, even if the "check for wi-fi" box is unchecked, if our router is not at the top of the list in "Advanced," then the computer will try the other routers in order. So far so good. Happy New Year.

I am glad that I was able to help a few people out with my earlier post where I advised to try and uncheck the "ask to join new networks" option under WiFi network preferences.  It seems like I may have found out another bit of information about this issue though.

I ended up returning the original machine on which I first experienced the WiFi connection problem.  The notebook was having some freezing issues, unrelated to the topic of this thread.  I now have a brand new 13 inch running Lion, the refurbished system I had was running Snow Leopard.

To make a long story short, the "ask to join new networks" option has always been checked on this new system from the time I took it out of the box and I have not experienced any connection problems.

So what I am thinking now is this issue can be fixed with a simple reset, just by unchecking and checking the option again.

Of course if things are working as they are, I would probably just leave them as is.  On the other hand, if like me, you like the computer to search for new networks automatically you may just want to try and uncheck and recheck this setting.

The other possibility is that this setting works on Lion and not on Snow Leopard.  It could also be that some systems may have hardware issues which make the WiFi not function properly when it comes to this setting.

I am interested in seeing if just resetting this setting helps some of you, especially people like Halidor who also commented on the fact that unchecking this setting is only necessary on some of his machines using the same wireless network I assume.

I hope this additional bit of info helps some more people.  Sorry for the long post and a Happy New Year to all!!

Yes the system will try the WiFi networks based on the order they are in.  The system should not be losing connection once logged onto a given network due to the fact that it starts to look for other networks though.

Unchecking the Ask to join networks worked. I, at this point in time, have had no problems for 3 days. I have AirPort at the top of the list and all is well. Snow Leopard is the OS of choice here as I have legacy apps too valuable to blow away.

1. Go to system preferences under the apple icon on the top left corner of your screen and then click on network.

 

2. Click on WiFi on the left side

 

3. Now on the right side you will see a box and next to it will be written "ask to join new networks".

 

4. All I did was uncheck this box and it solved my problem with losing Internet connection for the most part.

In the 83+ pages of this thread, this post is the winner. Along my lengthy troubleshooting, I had somehow unchecked this box in the process. My wifi problem went away, but I didn't realize this was what fixed it. When I first read this post about unchecking the box, I was skeptical, but I re-checked the box to test the theory, and it actually caused the problems again. Unchecking once again fixed it.

Perhaps the problem is already fixed in Lion, but I am not upgrading, and shouldn't need to. Apple is still supporting Snow Leapord, and should back-port whatever fix they have (if it truly is fixed). If it's not yet fixed, well, for Pete's sake--fix it. They should at the very least give people an option to enable more debug info in the system logs so we can send it in and help them help us.

In any event, I sincerely hope this cuts down on the bloated, unhelpful discussions people are having on this thread.

Thank you gregapp.

I just checked my WiFi settings on my iMac and that box is not checked. Must be default setup on Desktop as I've never touched that setting.

Thanks for that, but just knowing that you have an iMac without that box checked doesn't really provide enough context for that post to be useful.

1. What version of the OS are you running?

2. Are you having the same problems described in this thread, or have you not had any problems and just wanted us to know that the default setting works?

Also, if you use the "quote" button in reply to this post, it'll help keep the context going so people don't have to search back in the thread.

Hmm, so I guess unchecking and checking again would not fix the problem on Snow Leopard.  It seems the box just has to be left unchecked in Snow Leopard.  It also could be an issue with older hardware that has nothing to do with the OS.
