10.6.5 and wifi issues

Having the same issues as other people on 10.6.4 and also 10.6.5, I've run through the various fix suggestions and nothing sticks beyond a day. My imac running 10.5 has no issues as well as my iPhone 4.

Well, at least some of you are getting their problems resolved. I just tried the latest reports of success, with no luck. The only thing I couldn't try was WPA2, since my SMC Baracade is too old to have it. It is set to channel 6, though.

Did you set it to 6 or was it already at 6? Make sure you've changed it at least once. So if it was 6, make it something else. Shot in the dark but better to say it than to go hours of frustration before realizing. =)

It was set to auto before, but in a previous attempt after 6 didn't work I set it to channels 1-11 one at a time.

I'm currently in the process of reinstalling 10.6.4 by installing from the DVD and then upgrading to 10.6.4 from the combo updater.

If that works, I guess I'll wait until Apple "officially" fixes the problem or wait for a few months. I've wasted over a day at this.

Hi, I am currently having this new wifi problem on my mid-2007 macbook. I tried repairing permissions so far but that hasn't helped. All networks around me will suddenly have "no bars" and I just have to wait until it decides to work again... I'm not going to rack my brains out over this because it seems like apple's problem... How long until they acknowledge this? Boy I wish I had backed up my computer before this...

My first MacBook circa 2007 with fresh Snow Leopard install. Decided to blindly run updates...Combo update 10.6.5 was approx 1.2gig. After the required reboot I too had little to no reception with the WiFi radio.

I tried removing the three pref files mentioned in this thread...also tried changing wifi channel on my router. Oddly I have multiple wireless networks in my house on separate channels. One was WEP and the second is not secured. Both had major issues due to lack of connection and timeout errors.

I did permission repair and multiple on/off and connection attempts seemed to get me connected. Hope it does not end up being a persistent problem

Glad to see Microsoft and Linux are not the only OS's subject to breakage on updates....Yes another reason yo backup. If it is a firmware issue, backup may not help though.

Nope it is a persistent issue... Hope Apple or a knowledgeable user figures it out. I may be inclined to do a clean install just because the laptop is new to me and no issue of loosing data.

There must be some corrupt file for wifi settings. Possibly in the user folder and elsewhere. I have been fighting with this to try and determine what is causing it. It seems to me, it may be just the wireless networks that had been saved.

I think changing the essid has the greatest effect vs. changing the channel. It seems the range is really diminished. As stated I have two essid's running in the house, one Asus Router on channel 3 and one Linkys acting as just an access point on channel 8, each with unique essid's. They are only 30 feet apart. With the mac I had to get between them to see both. Any other machine in the house can see both from anywhere inside the house and at least 75' radius outside.

I am having a wifi issue since updating to 10.6.5. At first, only wifi would not work and I tried repairing permissions, restarting and deleting the files suggested in this discussion and else where but nothing worked. Now I don't have wifi and I also have lost ethernet access. I get a self assigned IP address whenever I try to connect using DHCP and if I try to change the settings manually I still get nothing. I'm away from home on business so I guess I'll have to reinstall the OS when I get back.

I am also experiencing some weird wireless behaviour with our 2008 13" White MacBook since upgrading to 10.6.5.

In our home office, which is situated at the back of the house, which is where the wireless router is located, the MacBook connects fine and as expected shows full signal strength.

However, when I walk through to our front room it drops the connection and will not reconnect. Once the MacBook has dropped the wireless connection after moving through to the front room it no longer shows our wireless network in the list of avilable networks. Trying to force it to connect manually by entering SSID and password doesn't work. If I subsequently walk back to the office it will reconnect.

However, if the MacBook is booted up or restarted in the front room it connects fine (showing full strength or one bar down) but if I then walk through to the back room it drops the connection as above!

This behaviour is 100% consistent. On 10.6.4 the MacBook was absolutely fine. All other devices (including an iPhone 3G on iOS 4.1, and iPod Touch and various Windows devices (including the MacBook booted up in XP under Boot Camp) all work fine so this looks to me very much as though it's a 10.6.5 glitch of some sort.

I'm, sort of happy, to report that I reinstalled 10.6 from my DVD and then applied the 10.6.4 combo update.

My Wifi now works fine, except it's back to not automatically connecting to my network when it wakes from sleep. I can live with that.

Hopefully, Apple will fix this, soon.

Do any developers read this?

Does anyone want to sign up as a dev to report this bug?

My guess is Apple is hard at work trying to break the Hackintosh world, leaving legit users to bug test their software.

Might sound silly, but I just notified Steve two days ago, just like - I hope - many others did 😉
Apple will never admit mistakes (not since 1983). Not with iPhone4 not with this. It will be some crappy third party component they used "over 3 years ago"

Lol, you just got to love Steve and his gang 😀

Yes, I did yesterday. And I left a reference to this discussion.

i'm very disappointed. got the first MacBook Pro "17 that came out.

never had any problems with updates.

now my wifi works 2 or 3 minutes.. then it stopps working.

i still can use the lan. but i'm a bit angry that i didn't wait a few days with the update just to know if it works or if there are any problems.

if we have to wait for Mac Os 10.6.6 it will take another 5 Months or so 'til it comes out.

Same problem here with 10.6.5 combo update on my early 2008 MacBook Pro. Wireless connectivity is nonexistent after upgrading. I have tried every non-network administrator fix listed. The problem persists. For me, this problem exists when at work. Since there are 2000 computers at my workplace, I can't request for the network administrators to change the whole network configuration for an isolated issue such as this. Thank god my MBP is not my primary machine at work otherwise I would be in serious trouble. This is a mess. I hope Apple can resolve this quickly.
