Upgrade to 7.6 broke my network

We had this issue as well.

We reverted to firmware 7.5.2 and then reinstalled 7.6 and freshly reset the wireless settings and it seems to work now. Annoying, but at least we are back up and running!

Best of luck!

I had a similar problem after upgrading this morning.

Well, the UI message was the same, not sure about the Console messages.

Bizarrely after trying repeatedly, including rebooting computers, airport, etc. I left it for half and hour and came back the problem had disappeared and everything is now working fine.

I cannot explain what happened or why but my network is reliant on two Airport Express units to connect to the Time Capsule, i.e. ADSL Router -> Time Capsule -> Airport Express -> Airport Express -> MacBook Pro.

Perhaps it took a while to sort out the overlapping wireless networks which was a new feature of this version of the software.

FWIW, my update went smoothly.

My setup is:

Vista PC

XP laptop

ipad v1

ipod touch v2

3 Airports with ethernet connection (1 creates an N network)

2 AX units that connect to the N network created by an AX

1 AX that connects to a linksys wireless G network

All AX units are the newer N version

Remote app on all the portable devices continues to work

Airfoil still works

Didn't have to reset my network, it all worked without a glitch

I updated to 7.6 and can only connect with some devices:

iPhone 4S (AT&T, iOS 5.0.1) - can connect

iPhone 4S (Verizon, iOS 5.0.1) - cannot connect

iPad 2 (iOS 5.0) - can connect

iPad 1 (iOS 5.0) - cannot connect

iPhone 4 (iOS 5.0) - can connect

iPhone 3GS (iOS 5.0) - can connect

AppleTV 2 - can connect

AppleTV 1 - can connect

MacBook Pro - can connect

Update: Downgraded to 7.5.2 and all devices can connect again.

Update 2: Re-upgraded to 7.6 and all devies can connect.

I use an Airport Extreme Base Station and an Airport Express to boost the signal. I updated the firmware notice and now nothing works. Only connecting directly to Cable modem via Ethernet works.

Advise please. I have lost my wireless network.

iMac OS 10.6.8

Man, there's a reason I'm still on 7.4.2 ... this makes two straight updates that seem pretty messed up. I guess if mine aint broke I won't try to fix it. Glad I waited this time.

i have a timemachine and airport extreme (2.4/5ghz)... after 7.6 update to both units today i cant use wireless at all..... resetted to factory defaults and both units are detected on airport utility....

network bridge mode seems to be broken...

OK, after d*cking around with my wireless for most of the day after having done the 7.6 upgrade I was finally able to get everything working again by doing the following:

1. Upgraded all to 7.6

2. Reset Time Capsule and reconfigured. Note: If I tried selecting the "Allow network to be extended" checkbox, I would lose it again upon updating and have to reset once again.

3. Reset AEBS's, reconfigure, selected "Use ethernet to connect to and extend my existing network" (not sure if that is it verbatim, but you get the idea).

4. All working again, network extended again, in spite of NOT being able to select the "allow network to be extended" checkbox on the TC setup. just double checked with Airport Utility, and it did not autmatically become selected by virtue of adding on the AEBS's the way I did.

Works beautifully for me now - YMMV

Everybody keep resetting and trying again. I updated 2 Extremes & an Express to 7.6 and all went well. I had had major problems with 7.5.2, and had downgraded mine to 7.5.1 and waited. 7.6 has given me no problems. I would suggest hard resets and walk through them like new setups.

I just upgraded. The first issue I had was the airport utility would no longer automatically discover the basestation. I have to manually enter the IP every time. Anyone else have this issue?

As for device connectivity, I only tried one so far device- Win7 and it connected fine to the network.

Hello all:

I am certainly not suggesting that the problems above did not occur.

I do want to indicate to others that read this thread that the 7.6 firmware update for my Airport Express worked properly (in my case). I only have two devices that connect wirelessly and both work just fine. The Express is used as a bridge. I did open the Airport utility and when it detected the update, I let it do its thing.

This wonderful update broke my network as well. I see people downgrading to 7.5.2...but where to download the firmware? I've searched Apple's site, but can't find.

Thanks so much, and thank you very much, Apple.

I'm having the same problem. Still no reply from Apple, I see.

I found this in another forum post:

Open airport utility, click on manual set up, click on version, then select [old firmware version]. It will upload that version and restart the TC. You can also do the same if you have a Airport Express.
