Having upgraded to lion my imac drops the internet connect when not active

I have just upgraded to Lion and when I leave the computer unattended for a few minutes it drops its internet connection - therefore does not collect any email until I click on the Airport icon and reselect the network. Also when starting up the and automatically loading Firefox the home page shows the previous download.

I FINALLY SOLVED THIS ISSUE!!!!
New routers have "mixed" modes for your network; this means that it will automatically choose the best option between wireless-B, wireless-G and wireless-N network modes. I used to experience this issue using the 2.4 GHz. mixed mode wireless network.
Thankfully, my router can create 2 networks: a 2.4 GHz. network and a 5 GHz. network.
When I randomly changed this value to "use only wireless-B and wireless-G" trying to fix an issue with a wi-fi expander, the iMac wi-fi issue dissapeared! I tried it with wireless-N only, but it didn't work.
So, finally, I have a 2.4 GHz network with only wireless-B and wireless-G modes which works PERFECT with the iMac, and a 5 GHz. network with a mixed* wireless mode for everything else mode.
*PD: by "mixed" mode it means that the router will automatically choose between B, G and N network modes as it fits better.

My iMac drops the internet connection but mantains the wi-fi network.

I have a late 2011, 2.7GHz Intel Core i5, 27" iMac with 4GB Ram. When I power up the computer everything goes great, but after 3 or 4 hours (top) the internet connection stops working; and by this I DO NOT MEAN that the network utility turns off, or that it doesn't detect any netwoks. On the contrary, the computer stays connected to the wi-fi network and detects everything, but it simply has no internet connection; it even stops communicating with my iphone through itunes (with the wi-fi sync option), and crashes LAN games when i try to play at home. When this occured for the first times I just turned off and back on the network utility, but the problem continued and I had to keep turning off and on the network (it wouldn't stay connected for more than 5 minutes). I checked with my laptop (the last alluminum macbook ever available, as well as with my mom's black macbook) when the internet stopped working in the iMac (just to check that there were no issues regarding my ISP) and the internet connection just worked great in it, and it didn't drop at all! It also worked perfectly with my dad's windows XP dinosaur laptop.
At the beggining I thought my wi-fi router had gone bad, so I changed it for a brand new wireless-n ready router (it turned out that i wasted 180 dollars, because this wasn't the issue, and I had already trashed my old router). At first, I used the wireless-n feature, but other gadgets stopped working with this type (a play station 3 and a nintendo wii). I then configured it with a mixed mode, and everything has worked perfectly (including both macbooks, an ipad 2, an iphone 4s, 4 blackberries, a play station 3, a nintendo wii, 2 network printers, 1 network scanner, a 3TB network hard disk and 3 led tvs that come network ready, along with their respectives network ready surround soundbars).... EXCEPT FOR MY IMAC! So DEFINETELY MY ROUTER IS NOT THE PROBLEM.
I've been an avid apple user for almost 10 years now, and this is the first time I encounter this type of problem (it's my first iMac), so I'm pretty much out of logical options. I've already moved my router closer to the computer, I moved my wi-fi connection to the top of the list in the network utility.
I even had to re-write this whole message again because i clicked on "Post message" and it had no internet connection, so it displayed a no-internet alert in my browser.............
PLEASE! HELP!!!!
PS: all my apple gadgets are always up to date.

My airport express frequently drops the internet connection. Once I unplug it and re-plug it in, everything is fine until it drops the signal again. This happens on a regular basis. Is there anything I can do ensure it maintains the internet connection?

My airport express frequently drops the internet connection. Once I unplug it, and re-plug it in, my Macbook Pro17,IMac 24, iPad air and my wife's Acer 15 works fine until it drops the signal again. This happens on a regular basis. Is there anything I can do ensure it maintains the internet connection?

It is tricky..
But yes it can be done as long as you use a different IP subnet to what is being used for the internet..
So I need to know what modem router you have?? Does it have wireless as that would make it very easy?
What IP is the computer getting?
Then I can give you the details to setup wireless statically on a different subnet.

My MBP keeps dropping the internet connection

Since yesterday, my MBP (Late 2011) keeps dropping the internet connection from my Airport Express. I'm still connected to the network, it just loses the internet connection on the MBP. I restart the computer, and it works for a few minutes. I turn off router, and it works for a few mimutes...but no matter what I do, after 2-3 minutes, I get the exclamation mark in the wifi indicator saying there is no internet connection.
And this is only happening on that single MBP. All of the other devices in the house, another MBP (mid 2012), an iPad (retina with lightning connector) and 2 iPhones (one 4 and one 5), can all connect. And the router we have is an airport express.
Why is this happeneing only on the one computer, and how can I fix this?
Thanks.

First, changing your DNS settings could not possibly have any effect on this problem.
When you see an exclamation point in the Wi-Fi menu, from the menu bar, select
 ▹ System Preferences... ▹ Network
Click the Assist me button and select Assistant. Follow the prompts. You may get a warning that Wi-Fi is not available, that you're too far from the base station, or that you're using the wrong password.
Assuming that you've ruled out those possibilities, click the lock icon in the lower left corner of the preference pane and authenticate, if necessary. From the Location menu at the top of the window, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.

E1200 - drop the internet connection

I previously owned a wrt54g G router and had that for many years before it finally died. I wanted to stick with Cisco since the last one lasted so long and never gave me any issues. I bought the 1200 and setup was pretty simple as the user interface was the same. The first issue I had was that the router would drop the internet connection and I would have to disconnect the ethernet line from the router and plug it into my ps3 or other device to get the modem to activate the internet again. Somehow the router will not grab a signal once it is lost. Reseting the router will not work or will unplugging it. This has happened about 3 times already in about 2 weeks. My home is about 3000 sq ft and although the signal in my office used to be at 2 bars with the G router I now have 3 bars so not that big of a range difference with the N router. I will be returning this and switching to a Belkin to try out.

There are many reasons why you experience poor signal or connection. Your intermittent wireless connection has a relation to the kind of setup that you have in your home or office. Is the connection dropping on all wireless computers or just one?
A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
1] Open the software and go to the option which says "Router Settings"
2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
3] Lower the MTU (Maximum Transmission Unit) from 1500 to 1492 or less (usually found on your router's main/ basic setup page)
4] Then go to the Wireless tab, keep network mode as mixed,
For Channel Settings of 2.4 GHz you can make Channel Width to 20 MHz only and Channel to 6, 9, 11..
For Channel Settings of 5 GHz you can make Channel Width to 20 MHz only and Channel to 40 or 161...
These settings would have surly helped you...

IMac hogging the internet connection from PC

I have a serious issue with my iMac hogging the internet connection from my boyfriends PC. If I download he can't even look at a youtube video. Does anyone have a solution or an explanation?
It's driving us both mad!

Hmm. Basically it sounds like when you connect you 'steal' the Internet connection and I can think of two ways that would happen. Open System Preferences and select the Network tab. Now click on the advanced button then in the top tab click on TCP/IP and you'll something like this:
Note that in the graphic above, next to Configure IPv4 you see Using DHCP. I'm wondering if yours is set differently. For that matter, I'm wondering how his computer is set up too.

HT3546 Although I am connected to the internet via Airport the internet connection does not stay on and comes with a "time-out" message. The airport connection is still on however. I have recently bought an old Mac Book 1.1.

I have recently bought an old Mac Book after having purchased an iPhone and iPad.
The internet connection (via Airport) keeps timing out while the Airport connection is still on as confirmed by the Mac and shown on the task bar.
Any ideas?
Thank you,

N97 The internet connection would not disconnect a...

Dear guys,
I have another issue of N97.
The internet connection would not disconnect after the application is closed.
eg. OVI, internet browser, MAP, opera and all application is require internet access.
Anyone have the same issue as me or solution on this matter ?
Best regards
Anderson

a network operator issue might prevent the 'E' from disappearing even after the connection is closed, i had this issue a few months back, i was on vodafone back then. In my case, the connection would close but the 'E' won't disappear. I'm on Telenor now, and i don't have this issue no more. To confirm, check SETTINGS/CONNECTIVITY/CONNECTION MANAGER,
next, go to SETTINGS/CONNECTIVITY/ADMIN SETTINGS/PACKET DATA and make sure WHEN NEEDED is selected under PACKET DATA CONNECTION,
Next, make sure you don't have auto update enabled for home screen widgets.
Press and hold the red key for a while, this will force close active packet data connections.
Laugh, and the world laughs with you. Cry, and the world laughs louder :-)

I want to update my iphone which has 6.1 to iOS7. Can I do it thru the service center or do I need to do it on my own. Updating at home is lot more inconvinient as the internet connection is not stable.

I want to update my iphone which has 6.1 to iOS7. Can I do it thru the service center or do I need to do it on my own. Updating at home is lot more inconvinient as the internet connection is not stable.

To add to templeton advice, you need at least 3.5 GB free space to update directly from iPhone.
And don't forget to make a backup at home before you proceed.

My mac keeps dropping the internet connection

I have a Mac that has worked for 2 years great. Recently it drops the internect connection and the only way to get this back is turn of the Airport, turn it back on and reconnect to Wi-Fi.
Any ideas ?
David

Wifi problems seem to crop up a lot on here and unfortunately there doesn't seem to be a 'one fix' solution.
However, I have seen that sometimes any one of the following can help some users although, unfortunately, not always. A bit hit and miss I'm afraid - and in no particular order:
Check wifi security - if it's WEP change it to WPA or WPA2 (preferably, as it's more secure)
See if using OpenDNS numbers to your network settings as described here helps:http://use.opendns.com/#mac
Change the wifi channel on the router
Create a new Network Location: http://support.apple.com/kb/HT5289
Reboot the router

Airport Extreme keeps dropping the internet connection to my mac

Hi, for a while now my airport extreme has been dropping my internet connection to all my mac computers. Its just the internet that drops i still have connection to the airport because i have a external HD hooked up to it and i can still access it when the internet drops. I dont think it has anything to do with my macbook because i have taken it friends places that have a wireless router and it never drops there. The airport usually drops when im on youtube watching videos. It always seems to drop when the video is less then half way done loading. I would extremely appreciate the help. Thank you for your time.

My problem is gone!!!!! I found what my problem was! So... after many days of being frustrated with the dropping. I phoned apple. They said it might be the service provider. Ok, well Apple said that some internet service providers don't like it when people use wireless routers. Because of people stealing internet and such. And since there is a lot of computers running off of my wireless router there are a lot of IP addresses connected to the internet opposed to just one set if you were connected to one computer by ethernet. So after my chat with apple, I phoned my internet service provider, Tbaytel. I told them that i have been losing internet connection for 5 months, and i would like it they would tell me what's going on. I told this guy what apple told me about the IP addresses always changing and he started to laugh at me and he told me that they don't know what there talking about.. After they told me to do the stupid shut everything off... now turn it back on.... is that light flashing?? Ok... now plug in the router.... All ******** basically. So after this guy being all confident telling me what to do and thinking that the problem will be gone, we wait 5 min and the internet drops again. So i tell him. There was a long pause....Ok ill try and do a reboot of the connection. He does this reboot thing and i have connection again. It doesn't drop. 3 hours later it drops again... So the problem came from the internet service provider, which was not a very good one. 2 months ago we swithed to SHAW and guess what? We haven't dropped yet!

2nd Base station drops the internet connection

I have a WDS network that uses a time capsule and a base station to connect to the internet. The problem with this is that the 2nd base (ie the remote) loses the internet connection after about 2 mins of turning it on. I cant find out why this is...perhaps a DHCP problem??
Please somone help?

HT4628 hi has anyone else considered going back to pen and paper after upgrading their imac to lion? i miss the internet connection that i pay for

In our house we have lots of Apple products and they all conect to our wireless no problems. My imac used to until I upgraded to lion and now it is almost useless. I have updated software and tested my wireless connectivity which is fine with other devices, am I missing something or should I be compensated for the time wasted trying to work!

How to revert your Mac to Snow Leopard
Be happy.

Since upgrade to lion on Mac pro the atv2 connection is extremely slow

I upgraded my macro to lion and since then it takes 3 min to pull up the library and times out when trying to down load the show. It worked fine under snow leopard. I have removed and redone the home sharing on both ATV2 and macro still have the same issues.

Which raises the question of why would you want to upgrade? Lion is largely cosmetic, and a lot of those cosmetic differences are not pretty
- removal of coloured icons in finder sidebar, making navigation more difficult
- no scroll bar arrows making navigation more difficult (essential if you need fine control of scrollling to move around in design progs like Illustrator/ Quark),
- autosave and versions, making everything more difficult through hideous beach balling on large photoimage files in preview or keynote if you make multiple and rapid minor changes
- dodgy compatibility with some versions of photoshop
- less control over where to keep your folder (apps have to be assiged to the app folder)
- less control over what information remains on your hard disk hidden from you (including versions of your personal files).
- if you use magic trackpad on your MP, you also loose the 4-finger swipe 'app switcher' gesture
On top of all these 'features' you get given:
- mission control, which is less configurable than spaces
- launchpad, which is effectively the same as having 'stacks' and 'grid' options set on your app folder in the dock, only lunchpad takes over your whole screen and is harder to navigate.
Now, that's all IMHO opinion, of course. As someone further up in this thread advised, whatever you do use Carbon Copy Cloner or SuperDuper to clone your current installation. If all is to your liking, you can always use that disk as a regular backup drive. If all is not, the way back to your flawless system is just a five-minute reboot away.
