Upgraded to 10.6.7 and wifi problem is back

How long ago did you do this?

Please keep up posted as to whether or not it continues to work as I did all of these things and it worked fine for a couple of days... then wouldn't connect one day... I did NOTHING and the next day it connected... then didn't the next! (All of these issues at school while, when I went home, it connected to my home network without a hitch!)

Hope you are more successful! 🙂

Just to update on my previous post. I've now been running for a week without any wi-fi connection problems after re-installing 10.6.7 using the combo-installer.

I'll update my own situation - my problem seems to have begun when I added a Time Capsule to my system, and enabled its wifi radio as a repeater of another wifi router in my home. There must have been some interaction or interference with two strong radios in the vicinity, and the symptoms were very similar to those described in this post. These symptoms were very apparent after the upgrade to 10.6.7, and were not a problem with 10.6.6. None of the proposed fixes in this post were effective.

My solution (1 week so far) was to disable one of the wifi radios. I left the Time Capsule wifi on and turned off the Belkin radio that is in the primary router that serves my wired network.

Those of you who are having issues in your work or school environment but not in your home - I suppose this could be a problem in Snow Leopard of not dealing properly with multiple wifi signals. In that case there may be nothing you can do about it except hope that later releases of 10.6 have (or will) resolve this problem.

I've tried twice to solve the problem, separated for three months jus to wait some update from Apple, and the problem is not solved whatever solution you try is just for a while.

Last solution I was able to connect reasonably fine was install rEFI, install Ubuntu. With Ubuntu in my Mac I've been able to connect without any problem to my wifi Network and even to the magic mouse. Once you restart in Mac OSX Snow Leopard the wifi was there connected and with a strenght signal, as in Leopard version was, but was unable to connect to my Magic Mouse.

So, I can coclude that Snow Leopard is not an ended version for old MacBook1,1 (Boot ROM Version MB11.0061.B03) the wireless connections are not correctly resolved. As soon as I come back with Time Machine to my old Leopard everything works fine as far as everybody would expect from an Apple product.

Is Apple Microsoftzing their products?

On my old MacBook, upgrading from 10.6.6 to 10.6.7 using the combo installer made WiFi either unable to connect, or would cause it to keep "forgetting" the password. I was able to fix it by turning off security at the wireless router, which is the Actiontec that Verizon FiOS gives us here near Boston. But I want some security, so...

Here's what Apple said. Use WPA2. 10.6.7 actually updates the FIRMWARE, too, so various things under the hood change functionality.

Believe it or not, that worked instantly!

The instruction for setting up WPA2 on Verizon are here http://www22.verizon.com/residentialhelp/fiosinternet/networking/setup/vzmi424/1 20467.htm

I really hope this sticks. And I hope my iPod is compatible with WPA2... BTW Ever since going to 10.6.7 we've had many problems on the MacBook. I spent 48 hours rebuilding it, and don't feel like doing it again.

I just bought an imac 21.5 last friday and i haven't any kind of internet yet, sometimes it works and other times doesn't load at all. I have a dlink 655 router that works flawlessly with xbox, ipad and windows laptop. I've tweaked my internet settings on my router and just switched to WPA2, did the PRAM, SMC RESET, had a time warner technician to my house and he said connection are good, so i will see if this works or i will be returning imac!!

I've upgraded some weeks ago to snow leopard 10.6.7

start the problems, sites don't load at all with mi wireless net...

it worked fine for 4 or 5 days ago, but now the problem is back!

i hope apple do something soon.

Did you try using WPA2 at your wireless router? It solved the problem for me. (It has made it difficult for OTHER devices in my house to get any bandwidth, but that's not Apple's fault.)

Gregg

yes, i use WPA2.

only happens on my macbook pro 15"

i didn't do anything and suddenly it works fine for 5 or 6 days....

yesterday it happens again

That is the real puzzling part about this. This week I was able to connect at school for 3 1/2 days outta 5! Monday it didn't work at all and then midway through Wednesday I got kicked off.

One of the teachers at my school has been unable to log on at home through her wireless also. I know she has not updated to 10.6.7 (MacBook) so there is another twist! Bresnan (her supplier and also our school's supplier) says it is her issue. I use a local Montanasky service (via phoneline) and have never experienced ANY issues despite running 2 iMacs continuously here and bringing my MBP back and forth daily from school. I have never failed to connect to my Airport Extreme...

Hopefully this will be figured out some day!

i've tried different routers also.....

virus?

I've had problems ever since upgrading to 10.6.7. Mac Mini purchased 3 years ago. Reading this thread, I've tried everything listed, not much luck, until I rebooted my router, Voila! Everything worked great for about a week, and then while watching a netflix movie, lost the connection, and haven't been able to use wifi since. Tried rebooting the router, and this time, nothing. Using WPA2, deleted locations, reinstalled them, tried using manual configurations. it is very frustrating.

Some people have talked about backing out the upgrade-- any pointers as to how do this?

hey guys, ive been having wifi issues lately too. i have the new imac 27" and wifi intermittently drops out. even tho it shows full bars in wifi. ipad2 and iphone4 seem fine though...

hopefully they'll fix this with an update?

Same problem here, tried everything suggested in every thread I could find on it and still no fix, just juping on this thread in hopes apple or somone responds with a solution..
