Firefox 5.0. 1 internet lost after sleep but email works - os Lion

Firefox 5.0.1 was working fine under Snow Leopard but since upgrading to Lion I can not access websites when waking from sleep. I have to go into Network Preferences Diagnostics to get it working. I am using a Virgin Media wireless router (Netgear).
Wireless and internet connection are there as email works straight away.
Macbook Pro 2008.

Thanks drewmaness.
Confirmed. It works now after setting network.negotiate-auth.allow-proxies to False.

Tap Settings > General > Reset > Reset Network Settings
Then restart the iPad.
Hold the On/Off Sleep/Wake button down until the red slider appears. Slide your finger across the slider to turn off iPhone. To turn iPhone back on, press and hold the On/Off Sleep/Wake button until the Apple logo appears.
If that doesn't help, try here > iOS: Troubleshooting Wi-Fi networks and connections

Must re-enter password after sleeping; but then works okay; what can I do?r

I see a lot of stuff on the boards about the signal dropping. Ours doesn't do that but we find that we regualarly must re-enter the password, or sometimes just re-connect manually even though the password is there.
I've deleted some of the "preferences" files to start over. I've also deleted the keychain files to make sure there are no duplicates. Maybe I'm overlooking something. I've also changed channels on our time machine to give that a shot. No fix with any of these options.
This is a brand new macbook so I would hope everything is working as intended. I'm running out of options...and my wife is frustrated! Ha.
Any thoughts? Thanks.

Try opening Network preferences, click Airport in the pane on the left. Click the Advanced button. Highlight your network name if it isn't already by clicking it. Click the "pencil" button. Enter your password there and click Add.
See if that corrects your problem. Not having a search function right now on the forums is a little frustrating because you can almost always find answers that way. I've never had your specific problem before so I'm kinda flying by the seat of my pants here. If this doesn't help you might try posting the same question in the Airport or Time Capsule forums.

My iPod is up to a 4.1 ios, and it won't update to a 5.1 which I need for some of my apps for school. It keeps saying that my internet connection is bad; but, it works just fine. What do I need to do?

If you get a network timeout error, then disabling the computer's security software duirng the download and update usually resovles that error.
If that is not the error what is the wording of the error message.
Note that only a 3G or 4G iPod can go to iOS 5. A 2G iPod can only go to iOS 4.2.1

Firefox not working when PC wakes up after sleep but Chrome is working.

When laptop wakes up from sleep, already opened tabs in Firefox are not getting connected to internet. After two minutes opening a new Firefox window is connecting to internet. But this problem is not happening with Chrome.

When you are doing this, set the drive to never sleep, slider completely to the right and display sleep to something like five minutes. Or just hit Control-Shift-Eject, to sleep the display. Uncheck "put the hard disks to sleep..." That said, the firmware on the externals may be spinning them down. But this shouldn't be happening if they are being written to.

My brand new Macbook PRO i5 can't connect to internet after sleep? It works fine after reboot.

I have a brand new Macbook PRO with the latest OS and the latest EFI. I haven't installed any 3'rd party products except Moneywell for my private finances. After a couple of days it couldn't connect to internet after sleep. I run the network diag and it says the connection is OK. Log out/in doesn't help. I have to reboot everytime it wakes up after sleep. Any clue?
br,
DAVID

I am having the exact same problem. It started with 10.7, was fixed with 10.7.1, then came back again with 10.7.2.

Airport connection lost after sleep mode

Hello everbody,
Each time I send my PowerMac G4 MDD Dual 867 to sleep it won't to connect to my (or rather to any) Airport network anymore after waking up, it just seems as if Airport is completely defunct after waking up.
My iBook G4 works without any problems on the same network, by the way.
I know the workaround with restarting IPv4 networking (described here: http://discussions.apple.com/thread.jspa?messageID=1122310&#1122310) and I have also created an AppleScript for automatising this process, however I am still wondering, if this issue will ever be addressed by Apple, since it is still present for me in 10.4.6.
Best regards,
Björn Wilmsmann

Okay, this might not solve your problem, but I had a similar problem when I switched from WPA2 to WEP on my Airport, therefore also changing the password which again somehow got my Powerbook confused.
I went into System Preferences > Network > Airport and looked at my "Preferred Networks" list (Not "By default, join..." > "Automatic"). Then I edited my airport network in that list (the small "Edit" button) and I saw that the password somehow was corrupted. When I corrected this error my Powerbook began joining automatically after sleeping again. Strangely, this setting has nothing to do with the Keychain Access, even though you can find your base station's password there too...
Oh, and I might add: My airport is on a closed network and is therefore not "visible"...

Shared computers lost after sleep

There are three computers normally appearing under "Shared", to which I connect via my home network (cable, router, etc.).
One computer is a Macintosh (Powerbook G4, on Tiger), the others are PCs (one on XP, one on Vista).
Since I have installed Leopard a few days ago, those computers disappear from the "Shared" list after my iMac wakes up from sleep.
Any solution?
Thanks!

I had this too... tried all the remedies I read online, from deleting plists to tweaking MTU sizes... including the one that solved it for the above poster, but nothing worked more than a few hours.
What 'finally' worked was static IP reservations in DHCP on my Airport Extreme, and 'just' for my Yosemite Macs. My older Mavericks Mac and Apple TV don't have this problem... clearly something introduced with Yosemite. Personally, I think it's related to the new Continuity 'features', but that's just speculation.

Mouse gestures lost after sleep

I have a MacPro 1,1 using a USB BT module when, login from boot gestures work fine. But as soon as I log back in from a sleep the mouse works but the gestures do not. Anyone experiancing similar issues? This is happening with a magic mouse and magic trackpad.

From the Belkin site:
Can I use Belkin Bluetooth adapters on my Apple computer running MAC OS?
As long as the Apple computer in question is running Mac OS 10.2 or later, then the necessary Bluetooth drivers are built into the operating system. All you should need to do is plug it in and you should be able to use Bluetooth.
The exact Bluetooth services you can use will be determined by the services offered by the Apple Bluetooth stack.
This would seem to put the bug squarely in OS X's camp.

Browser not connecting after returning from sleep, but email and imessage working fine

My Browsers are not able to access the Internet after returning from sleep. This effects other browsers (Firefox & Chrome) as well. The connectivity from mail and iMessage is working fine. I am also hardwired and not using WiFi.

I have the same problem since updating to Yosemite, works fine after restarting but once it goes in to sleep it affects email as well as browsers, I have a broadband connection. Also accessing the app store is hit and miss, it's either working or simply not not working.
It also affects other devices trying to connect to the internet over wifi via the airport time capsule, the problems started after installing Yosemite.

Password after sleep but not when starting?

I have set the option to require a password immediately after sleep or screen saver begins, and that works fine. Waking from sleep requires a password. However, if I shut down the computer and then start up again, I'm not required to enter a password. Can't seem to locate the settings to require a password in that situation.Any suggestions?

That's under users in system preferences. Unlock if necessary and look under Login Options -> Automatic Login.

Nokia won't wake up after sleep mode! ( Work aroun...

WCH1.... Posted this in my first thread
Found this somewhere, and it worked for me.
Freezing in sleep mode:
Go to the device manager (you can go to control panel and click on SYSTEM and then device manager will be in the upper left corner). Go to the very bottom and find Universal Serial Bus controllers.
Click on the arrow next to it and it will reveal 2 "USB Root Hub" devices. Double click (or double tap).
On each one, choose Power Management tab from the top. Uncheck "Allow the computer to turn off this device to save power". Then click on OK.
Be sure to do this on both device ISB Root Hub listings. ( The Credit is not mine) but much needed because they keep posting in my first thread !

Well my solution may not be the most cientific one but it works for me (at least until the real solution comes to the public)...
My computer has the problem that when it goes to sleep mode she never comes back... but it the screen that does not comes back... all the system is workin in behind (its like the brightness level was set on the less power possible) so i had to turn off the computer and had to do for a long time some times i had to wait that the computer cooled off a little and then try again to turn it on... I some tried things that the support page of apple said it could be... but did worked out... i dont know i think is a problem over 2 factors...
1. heating (the screen generates to many heat but, TO MANY!)
2. tiger os the OS "sleep mode" (it knows that the screen its heating a lot and tries to go to sleep to prevent over heating and damage)
So based on this i tried conecting a external monitor to the computer while she was unable to "awake" (or to show some thing in the screen)... and it worked whit no problem at all... so my conclusion was to prevent the over heating (1st factor) and the sleep mode (2nd factor)... so I deactivated the sleep mode setting up the computer to a never sleep mode... and to prevente the over heating well I use a low bright and when i need more brightness (to se the colors of what im doing or some thing like that) I use high brightness... when I away I set the brightness level to no brightness so there is no over heat and no sleep mode (cus if it is deactivated and it over heats it will go to sleep anyway...
Soooooo....
1. deactivate Sleep mode...
2. Activate a Screen saver...
3. And remember to contro your brightness your self... and turn it off when you are not using your computer...
well i hope it works for some body :P cya...

Bonjour sleep proxy not working; Mountain Lion (10.8.1, 10.8.2) not waking up for remote management, itunes library

Since updating to 10.8.1 (I'm currently on 10.8.2), my Mac Mini no longer wakes for network access.
That is, when I attempt to connect remotely to the computer (i.e., mac mini is at home, I am at work), the computer never wakes up.
I have an Airport Extreme 2011, I believe; I updated it to the latest firmware a week or two ago. (Now that I think about it, maybe it was after this firmware update that the Bonjour sleep prox stopped working?)
Ideas?
My system:
Mac Mini (2011) with 8gb RAM
[added 2nd hard drive -- SSD]
Mountain Lion 10.8.2
Connected via ethernet cable to an Airport Exreme (2011)

Since upgrading to 10.8.2 I have had this issue.
I have 'Wake for Network Access' enabled but I am unable to wake my Mac Pro from my AppleTV2 using Home Sharing.
If I reset the PRAM, WOL works the first time the Mac goes to sleep but after that it wont work.
The Mac Pro still periodically wakes up (as in the fans and HDDs spin up, no GUI) to keep the network address alive but nothing can actually wake it, (except once on the first sleep after PRAM reset).
This was not an issue prior to 10.8.2.
I have also noticed since upgrading to 10.8.2 that after waking the Mac, it takes approximately 10-15 seconds for the network to re-connect. This is via a wired ethernet connection.
This also was not an issue prior to 10.8.2.
I really hope this is fixed with 10.8.3.

Lost internet connection after sleep

When waking from sleep my internet connection is lost and I have to click the airport icon and reselect my network to reconnect. I dont have this problem with my MacBook, it reconnects automatically when when waking. Is there a way to set up the iMac (running 10.6.6) so that it reconnects to my my network automatically when it wakes?

Hi Rick,
I am having the same problem of the airport network not coming up automatically without pressing the network manually in the signal bar. I checked the system preference checks as you explained and still have the problem. Any other suggestions.
