I have two identical iMacs hooked up to a router. Both had no internet connection problems until now. One iMac works fine, the other just stopped. I swapped LAN cables and router ports but the iMac that quit connecting still won't connect.
View 3 RepliesI updated iTunes to 11.4. No sooner had I done that, than I lost the connection to my wireless keyboard (Apple). iMac, OSX 10.7.5..I inserted new batteries into the keyboard. That did not work. My Apple Keyboard connected by wire operates just fine.

a few days ago I noticed that my Late 2009 Macbook seemed to lose its internet connection every few minutes just for a couple of seconds only to reconnect. I have no idea why this problem suddenly started occurring, I had not not modified any hardware or software. Strangely enough, this happens whether I use Wifi (at work) or Mobile Broadband via USB ( at home) so I don't think it can be blamed on the internet connection. Stranger still, I should probably not be talking of losing my internet connection but of not being able to access the internet: While again being in a few seconds of slump, I checked my Mobile Broadband Manager and it was not disconnected, upstream traffic was occurring! Just the downstream was at zero. I run windows with bootcamp on the same Mac and there the internet works without trouble. I have all the newest updates installed.

My iMac is waking up from sleep in the middle of the night. The only clue to what is going on is that is says the wireless keyboard has lost connection.

My iMac keeps dropping internet connection. This has only been a problem since installing Lion, it often tells me there is no connection when my iPhone and MacAir work perfectly so i know its not the broadband itself. I also get the message that my network configuration has changed.

I have an iMac (without an Airport Base). It is connected to a Sky router through an Ethernet cable but still with wireless capabilities. The internet connection keeps dropping out at regular intervals throughout the day to the point that my partner may just throw it out the window! The router lights still show it is connected as does the wifi signal at the top of the screen. Our iPhones still work even when the Mac drops off.

Since last week my iMac (Early 2009, OS 10.7.3) has been dropping its connection to the Internet. I'm using a router connected to an Airport Extreme and connect to it via WiFi. I tried connecting via Ethernet cable from modem to iMac but it would drop the connection entirely, which is why I had been connecting via WiFi. I have no problem with my other devices (iPad, iPhone and MacBook, this one with 10.7.2 installed), they connect immediately to the Internet and all, even the iMac, are able to connect to each other.Â
I already tried restaring the Airport Extreme, zapped the PRAM, reset the SMC, repaired permissions, disconnected the router and Airport from the power source and it still won't connect. Last time this happened, my iMac went to sleep and dropped the Internet connection after waking. I put it back to sleep and woke it using the power button as someone had suggested in another post, that helped and the connection was reestablished. This morning the iMac it was working fine, did not go to sleep at any time and suddenly dropped the connection, which I haven't been able to restore since.Â

My iMac is connected to the internet wirelessly.
Every hour (or even more often), I get the message "Safari cannot connect to the Internet", followed by a prompt to run diagnostics. I run the diagnostics, re-select my network (provided via BT Hub) and pronto - the issue is fixed, by why does the connection drop so often. Surely this can't be right - I can't be doing that every time I want to go online. Â
Interestingly, my iPad (which uses the same network and Safari) never drops the connection, so it is something to do with the iMac.

My internet connection has always been very fast and I have never had any problems with its speed or loading of web pages. Over the last two day I have experienced extremely slow connection speeds and webpages have been taking forever to load. Is there a setting I can check or cache to empty to help speed up my connection? Or is there a disk cleanup to help get rid of whatever may be causing this problem?

Why does my Mac keep losing internet connection every 5 minutes - I end up having to turn wifi OFF and ON again each time.
As all other devices in the house connect seamlessly to the wireless router, the problem is only with my MAC desktop.Â

I have a 27" iMac running OSX Lion 10.7.3. Some time in the last 2-3 weeks, it has started to getting into a state where the kernel_task is using 100% of one CPU constantly. When this happens, it also kills my Internet connection and I cannot use the browser, email, Skype, Twitter, etc. I have tried putting it to sleep, closing all programs that are open checked the process list with ps to see if I could find anything weird, but it still keeps happening.Â
I have to restart the computer whenever this happens. It might happen again in a couple of minutes or not for several hours, but happen it does. I thought it might be Chrome or Mail for a while, but it happened today when those were not running.Â

Trying to get Mac to connect to the internet video D-Link router. When I click on my wireless the box that comes up shows a place to enter a password and I do so but the connect button is not active only the cancel button is active? Did find another box that gives about 6 choices of connection types this is geek to me. In the list of wireless connections there is one unsecured and it does connect to it.
