Q: 10.6.5 and wifi issues

Since I upgraded to 10.6.5, my MacBook Pro (Early 2006) cannot connect to my USR9110 (802.11 g) access point. 
From 10.6 on, there's been always troubles when resuming after sleep, but now even at startup the connection goes timeout.

All other devices (an iPhone,an iPad and a MacBook Pro (Late 2006) with 10.5) work perfectly.

I tried rebooting, changing  the wifi channel, updating the access point firmware, turning on and off airport, resetting the SMC, switching to WEP, switching to WPA, switching to unencrypted. Nothing changes, connection timeout. 

MacBook Pro 1,1, Mac OS X (10.6.5), early 2006

    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.

    Same here. All fixes stop working after a short time. Temp workaround is DCHP with manual address. This works but only while here on my network.

    I have had issues before and after the update on our corporate wifi at work.

    *BEFORE 10.6.5 update*
    - Sometimes computer would connect to the wifi and be online immediately. Once connected it works as normal.
    - Sometimes it would connect to the wifi, but not get an IP address via DHCP for about a minute. After a minute it would get an IP address, but still be unable to access the internet. Disconnecting and reconnecting might fix it. Sometimes it would take many reconnects before it would work.
    - Sometimes if it was really stubborn, restarting the access point would usually allow reconnect straight away.
    - All other devices, iPad, iPhones, Windows laptops work fine.
    - Our wifi base station is a Netgear WAG302 and runs both 802.11g and 802.11n.

    *AFTER 10.6.5 update*
    - Same issue as above still applies, but now if I do get online it disconnects automatically after 2-10 minutes.
    - After much research, I have found when it connects to 802.11n the internet works fine, but 802.11g doesn't work. When it disconnects it is dropping from 802.11n to 802.11g.
    - When it's not working, it appears to be trying to send data, but receives nothing back.

    *OTHER NOTES*
    - I hold down option and click on the wifi indicator to view details.
    - No problems at home on our 802.11g only network (Airport Express UFO style base station)
    - I can't change the channel or edit the settings on the router, however can put a tech support request to do so.
    - I suspect the issues before the update are caused by whether or not my laptop decides to connect by 802.11g or 802.11n, unfortunately I didn't check that before updating.
    - The issues with the 802.11g may well be a problem with our network here at work, but it seems strange other things don't have any problems.
    - If there was a way to force my laptop to ONLY use 802.11n, I suspect it wouldn't have problems. Unfortunately it seems only possible to change the entire network to do this, which I can't do.

    Looking forward to a fix by Apple for the 10.6.5 issues.

    We have two MacBookPro's 2006 models. I made the mistake of upgrading both to 10.6.5. Like others, I lose the signals frequently, and often get it back turning it off and on. I tried Steven Tannhill's approach, which I thought worked until after a few hours it stopped working. (things are a bit better actually.)
    I just wrote feedback to Apple but of course will never know if that was just wasting time.
    I will probably attempt to reload snow leopard from my disk and upgrade to 10.6.4, unless Apple fixes this soon. It adds much frustration to working.

    Haven't read the whole thread so maybe it has come up before.
    I updated my macbook pro late 2008 to 10.6.5 via ethernet (it's almost always plugged in) and had no problems until i restarted last night. Back in mac OS i couldn't get to a internet-page like google and others, but every thing on the home network was available.

    After some research I tried the method I read on page 1 of this topic;
    System preferences; Select the network-bus (for me it was the ehternet) and hit 'minus'-icon on the bottum. Page 1 describes rebooting but i tried it before that; hit the 'plus' icon and added ethernet back in the list. And YES I was back online!

    So thx, person on page 1

    PS: While my ethernet didn't work, I tried it via wifi and that worked just fine... Weird, but resetting the drivers (ore what is it?) via system preferences did the job.

    Hope it helps!

    10.6.5 has totally crippled my networking.

    DNS on a wired connection is resolving commented-out lines in /etc/hosts

    Wireless has been a disaster; it can almost never find access points. When it can, it disconnects frequently and then can't reconnect.

    Between this and the recent iOS disaster, I am very sad at Apple. This is not the quality we have come to expect.

    What security method is your wireless network using ?

    Here is an article I found for people who are complaining about noticing a of max. 54 Mbps after installing this update. The details in this article might explain it

    I have been having many of the same problems as everyone else. After updating this morning, I see "AirPort has the self-assigned IP address 169.254.xx.xx and will not be able to connect to the internet." I get no connectivity from Safari, Mail, iChat, etc.

    Oddly enough though, Firefox works as usual. I am able to browse, watch movies, and search in Firefox.

    Same problem here. After the 10.6.5 update the connection was better for a while but more difficult to repair when it did go bad.

    I moved channel from 6 to 1 because three neighbours also used 6, so I don't see anything special about channel 6 itself.

    Today thing were really terrible, so I made a new connection under a new name, instead of using the "Automatic" setting in the Network>Airport Preferences pane. This seems to have improved thing immensely.

    So far so good... but I shall not hold my breath. Come on Apple!

    One thing I have noticed. When I select what wireless network I want, I see the lock next to my wifi since I have it secured. Once it is selected and my Mac has joined the network, when I go back to look at the wifi connection, the lock is gone. I don't recall that from before.

    MacBook pro, bought June of 2007. All other devices working fine (iPad, iPhone, PC) over wifi. MBP is not since updating to 10.6.5

    I can get to the Internet using the recommendations in these posts but the connection is very slow, e.g. It can take over a minute for pages to load, syncing fails, mail.app loads the to/from/subject line, but takes several minutes to load the content.

    1) I am on at three threads which seem about the same issue.
    2) I have followed Steven Tannehill's second post about fixing this issue. At first it did not seem to work, but yesterday I had NO problem; that is I had no problem on this computer. We have 2 Macbook Pros (2206); the other is still having trouble. Applying the same "fix" yesterday, so far not working. But it took several on and offs, repairing permissions and a day or two for mine to 'behave.'
    3)Several people--I thought it was this thread but perhaps not--got contacted by an Engineer from Apple (Kenneth Wold) asking details. So at least someone there is looking at this.
    4) I did notice that, under Airport Utility, a setting was switched. I had my Airprt Extreme>Wireless>Radio mode: set to the non-N- setting. It was switched to automatic. (My card is a new g card, since there were antenna issues getting an n card.) When I noticed, and switched it back to the setting without N, I started losing the wifi again. Just switched back, and here I am able to send this.
    Good luck

    imdcoop,
    Did you get a card replacement from the Apple Store ? If so, your card should be abg compatible. Or do you have an external wireless g only card ?

    If you have the abg card, you could try switching to the A band on your wireless router and test the connection.
