new iMac 24" keeps dropping AirPort connection

hmmm

Thats strange...

I don't know much about this, but have you gone to software updates and updated everything, I remember when I got my first imac ages ago, the airport kept dropping untill I updated it. I don't know if it works with the new ones tho.

Hi,

I had this same problem when I got my iMac in March. The way I fixed it was to switch the Wi-Fi channel on my router from automatic to channel 11. Not had anymore problems since then, so give that a try.

I'm getting similar problems with my 20" I think its down to 10.5.4 from what I'm reading on forums.....I am getting connection drops and very poor signal. Anyone who has experienced this problem please let us know what you did....I have tried everything from changing my router's wireless channel, upgrading to latest firmware and reseting to no avail.....

Many Thanks,

I was having the same problem on my new Mac as well, what fixed it for me was to change my WEP from key to the more secure setting, I forget what it's called and I'm at work so I'll check when I get home.

Does the OP use a wireless keyboard & or mouse - 802.11G ?

What type of router are you using?

How far away is the router from the iMac?

Have you tried using a different router to see if maybe the problem is the router?

I had a cheapo D-Link and it had the exact same issues with my mini. Now with my AEBS I have no issues at all. The cheaper routers have issues connecting multiple computers specially at further distance's. I never had any good luck with a cheapo $30-$60 netgear, dlink, linksys futher than a couple rooms or 3 walls, they are very unreliable at those distances. Now if it's it's a higher end one $150+ then it should be just fine. My AEBS has a signal on the first floor of my 3 story building like 2 bars too.

I concur with nando.

My machine has similar issues, but the problems didn't start until I updated the firmware and enabled WPA security on the crappy D-link router I connect to.

Prior to that, there were no drops when the network was unsecured and running older firmware. Drops are almost certain to occur when another computer with a similarly crappy Hawking wireless adapter joins the network.

To cope with it for the time being, just turn Airport off, then back on from the menu.

However, I wouldn't doubt that 10.5.4 may play a role; 10.5.5 supposedly addresses Airport issues among its many fixes.

changed to channel 11, with no issues whatsoever.

Told you so! Not had a single problem with mine switched to channel 11 since March so you should never see that problem again.

I have the same problem, how do I switch to channel 11?
thx

My imac 24" Tiger was working beautifully connecting via airport to Linksys DSL router until i applied Airport Express Update 2008-002. It kept dropping the connection even thought the airport wireless icon shows full signal strength.

I scoured the net and for over 2 weeks applied every possible solution from deleting widgets to changing router channels and even removing all items sourrounding the DSL router... nothing worked. I even dug up the 2008-001 airport update and reapplied that but no good

I finally got so fed up that i re-installed the OS 10.4.7 with the "archive previous system option" and everything worked great. I then updated the OS to 10.4.11 and still everthing working consistently. I applied Airport Express Update 2008-001 and things went south.

I reapplied the 10.4.11 update again and things are back to working consistently.

Reinstalling the OS took a couple of hours but it really is a lot less painful than having an unreliable connection, while the Windows machines had no issues. Hope this helps.

kinda the same problem,
1st my macbook, the name of the router, apear on my mac, Ive select it and only the IP and one more field was sign in in my mac. And it had the same IP every time. (suspicius). No internet

2nd my iphone SAME ISSUE, only ip and one adress apear on the phone, (exactly the same numbers) NO Internet.

3rd my second iphone, same issue.

So the suspect is my router DLINK. no fix there.

Just bought a new Imac 24" as well. I was having this EXACT issue with 4 PCs in the house and never having any problems with the network.

I just switched the channel to 11 and I hope it works!

Thanks for creating this topic, and thanks to google for helping me find it

EDIT:
Still having the issue with the connect drop.

My first post on here, and I'm glad that it is a good one

I have also been having problems with my 24" iMac purchased in Dec 2008.

I just changed from 11 down to 9 and all is well.

Many thanks to the above for the top advice.

I'm having the same problem with my new 24" 2.6ghz iMac...I've Been using macs for 4 days now & I'm struggling!
I think my wifi is already set to channel 11.

Wirelessly posted (BlackBerry8320/4.5.0.81 Profile/MIDP-2.0 Configuration/CLDC-1.1 VendorID/100)

I have this problem with my imac and AEBS(n). It was so annoying I went to using ethernet, but I'll try channel 11 and report back.

We had similiar issue with Jun 08 17'' MBP that the connection of the wifi would drop then come back up.

We've tried everything, from switching the channel to 11 and what not.

The router we had was a WRT54G. In our house, we had iPhones, PS3, Wii all hooked up on one network

But we finally fixed it but the solution wasn't pretty.

We went out, bought an AEBS, bridged it with the other network...

So now, we have a network on 5ghz N-only for the MBP and a B/G for everything else.. works wonder!

The channel you change to might not affect the problem, it all depends what channels other networks are using. On my network I have three windows pc's, one iMac and my iPhone. The iMac is the only one which picks up more than one available connection, leading me to think that they are much more sensitive.

My advise would be to try a couple of channels until you find one which works.
