I'm currently running on Mac OSX 10.7.4. Access to my NAS via wifi is very slow as compared to accessing it via Windows. I've tested with both AFP and CIFS but both are equally problematic.

For several weeks I've lost internet connection on my iMac every day or so; the wifi icon changes to show a ! and is otherwise greyed out. My internet connection is via a relatively new Time Capsule (2011) which has an ethernet cable connecting it to my Sky broadband router. I moved to this new Sky broadband router in early Jan 2012 (changing to Sky as a Broadband provider) and it works nicely as a router. My iPhone, iPad, AppleTV and a range of other devices (including an Apple Airport Express connected to a Sky TV HD box to enable it to download movies) have continued to work on the internet without problems.
The IP address of the iMac (27 inch quad core i7, 8 GB RAM, fully up to date on Lion) disappears from the Network settings when the problem arises but the connection of the iMac to the wifi (and backing up to the Time Capsule) still works. I can even use a VNC app on the iPad to connect to the iMac on the same wifi LAN when the IP address has gone and the ! is showing in the wifi icon on the menu bar. To get reconnected to the internet, I just restarted the iMac and it was then back accessing the web nicely. Eventually the iMac would not connect to the internet at all. It would momentarily get an IP address from the router and then lose it again. I then tried taking the iMac to the Apple Store.
Various diagnostics run in store at Genius Bar and during the week and the problem (using the same account) was not replicated. On its return home, it was still not working on the internet. I then tried booting into 'safe mode'. This enabled a stable and reliable connection to the internet! After several days in this mode, I re-installed Lion and booted into normal mode again. The problem returned and has been with the iMac since. However, at least a restart of the iMac gets it straight back on to the internet again. I suspect some sort of corrupted network preference file or the like. But where? The disconnection from the internet can happen any time of day; for example it happened while typing this message but more often than not it happens when the computer is unattended.

My iMac is very slow. It only works on wifi. Ive got good cat 6 hard wire to cox business and its fast internet. but it wont work on the network. it says i need an ip address. it says the internet is connected but needs an ip address. Ive got it on dhcp auto. but not working. All other computers work fine with dhcp. It says the computer is connected but does not have an ip address. Not possible if its set in dhcp as that is supposed to give you a rolling ip address. Ive got a cisco gigabit switch that is working well with 10 - 15 other computers working fine on it. Ive changed the port multiple times in the switch. rebooted of course. nothing works.Â

for the last few days my wi fi cuts out. If I go to the diagnostics it turns back on. It says that my network configurations have changed but then allows me to access it. But the next time I go to use it it has gone again.

The phone recognises the network and it looks as though it has connected as it is ticked in the networks, but unfortunately it hasn't as my phone won't connect to the internet.Â

Since installing Lion I lose my wireless internet connection frequently - only from the IMAC, not from the IPAD or Dell. I called support and after quite a lengthy "try this" session, I was told that this was a known problem. I can always get it back but sometimes have to unplug the router.

i want to get an imac and put it in my room but there is no place to plug in my modem and router up there so i was wondering if there was a way to wirelessly setup my imac with the internet.

Before the 10.7.4 update the WIFI connection from the iMac 21.5" to the airport extreme router works fine!
Now it's failing several times a day! it looses the wifi connection and you are unable to see any wireless accesspoints or SSID's
Macbook pro, iphone & ipad + PC's still works fine!Â
The only way to get the wireless up and working again is to shutdown and restart the iMac.Â
In the log i can see alot, don't know if this is some clue or error occuring just after the wireless connection is dropped for unknown reasons.Â
"kernel: 2329.723808: ath_chan_set: unable to reset cannel XX (XX00Mhz) flags 0x10080 hal status 17"
"kernel: 2632.354892: ASSERT: Can not reenter VAP State Machine"
"kernel: AirPort: Link Down on en1. Reason 8 (Disassociated because station leaving)."Â
Turning off and on the wireless interface only shows the following in the log, and the wifi will not see any SSID's : "kernel: 71847.200440: switchVap from 1 to 1" Â

My brand new imac randomly disconnects from the internet. We have a BT hub - wifi. I have googled this issue and see that it is relatively common and it is incredibly frustrating. It is fairly simple to reconnect each time but it is driving me mad having to. It generally happens when the computer is asleep but sometimes in the middle of doing something.

My music library is on my iMac, located in a different room of the house than my home theater system with a decent Denon receiver and good Infinity towers. I have an iPod connector to the Denon which I can use, but the iPod has a limited library of songs, so I would like to somehow access my iMac music library and be able to play it through the home theater system. Hard wiring the components is out of the question due to length of run through several rooms of the house, no basement and cathedral ceilings. I already have my iMac and my Panasonic Blu-Ray player both connected to my wi-fi, and it seems there should be a way to connect both of them using the wi-fi. The blu-ray player is DLNA, but the Mac isn't, so that is out of the question. Is there any other way to get these components to talk to each other over wi-fi?

This problem never happens with my MBP - and it is running a CCC Clone of the same 10.7.x system. But whenever I restart my iMac 20.5" it never automatically connects at startup. I always have to touch the wifi symbol in the menu. After that I don't need to select my home network - it will then find it and connect. But until I do that it doesn't connect. This has happened ever since I've gotten this iMac. Also annoying is that the sound output upon startup always defaults to my Logitech headset regardless of how I left it set in Sound settings.Â

I have a Brother MFC-9340CDW WIFI printer which my iMac says it can't find sometimes when I want to print. I think I have narrowed the problem down to when my MacBook Air is on at the same time and using WIFI on the same network If I turn off WIFI on the MacBook I can print from my IMac. I am not sure if it is a router problem or what but we use the iMac and MacBook Air at the same time quite often. Checked on the Brother website - nothing.Â
