Oct 20, 2008 7:13 PMby rountrjf,I must jump in...
I just bought my new macbook pro 2.4Ghz the day after they came out...
I brought it home... got on wifi... and it worked!!! Then it dropped... then it worked... then it dropped...
Still does it to this day...
I go to work, wifi is rock solid...
Go to friends houses... rock solid...
Come home... unstable...
Another note... I have 2 Vista Notebooks and Nintendo Wii all rock solid on this same router. It's a D-Link WBR-1310... only had it for like 6 months or so...
No idea why this is doing this - it's brand new... after everyone bragging about Apple and it's perfect hardware/software combination I really am frustrated!
If anyone has a solution, post it PLEEEAAASSEEE! -
Oct 21, 2008 5:50 AMby SRamsesIV,I still have this problem on my MacBook Pro (even with 10.5.5) but it seems to have abated a little. I noticed recently that as long as my Mac is the only wireless computer on the network then it is fine. The very moment my wife connects to the wireless with her Windows PC, though, my connection drops and I have to reset it by turning my Mac's wireless off and then back on again. Once I do that, though, I am generally pretty good - it is still very annoying but at least I know to expect it now.
Is it possible that Apple has managed to reduce the problem to only affect those with mixed (Windows and Mac) wireless networks? My Wii and desktop Windows PC are both on my wired network and (not surprisingly) don't appear to affect the wireless side. -
Oct 21, 2008 8:25 AMby Michael Prior,Hi Rountrif,
This is a puzzling one, i have a MBP 2.4 running 10.5.5, i have no problems with it's wireless connection, we have Apple Airport here but i also take it out regularly & the WiFi works perfectly always, i know others in the same position. However we have other Macs that are running Leopard and the connection is not as good. I have mentioned this before but have you tried re installing Leopard & then up dating with the Combo up dates, re installing Leopard isn't a big problem. I believe this issue to be with Leopard but for some reason it only effects certain computers. To try and reassure you we have over the years had stacks of Macs with precious few problems so you're unlucky, on the other hand my nephew has a new Vista machine & the Wi Fi is terrible & my Father has just changed to a Mac after numerous problems with Pc's and is much happier, so it's not just Apple.
Good luck,

thank you for your message.
The fact that the newest generation of MBPs is still impacted by the wifi stability issue sounds like very bad news to me: before today I could convince myself that Apple was pretending not to know about it; now it is almost certain that they really don't know or don't care.
I would bring the MBP back to Apple before starting using it and becoming dependent on it. I hope Apple will be more caring about issues impacting the newest models than with the previous.

Oct 21, 2008 12:25 PMby dd-blues,I confirm this. I have a Mini Mac with 10.5.5 that periodically looses and regains wireless connection. The transmission rate is also low (average 11 Mb/s with router set on "g only"). I have on my home wifi network one Mini, one MB, one MBP, two PCs, and one HP printer. If I disconnect PCs, Mini no longer looses connection, signal strength goes up and transmission rate increases to 30-40-50 Mb/s. Mini's wireless card is a/b/g, not n.
I have Netgear DG834pn router with either "b&g" or "g only" options. I use "g only"
Interestingly, this does not seem to solve the problem for the MB, which does not reconnect after waking-up (but never looses connection once connected). MB's wifi card is a/b/g/n.
So, from this very limited experience it appears that there is a conflict of some Macs with leopard with networks containing PCs.
I still do not think it is the router; my MPB (10.5.5, with wifi card a/b/g/n) works well regardless of other equipment connected to my local network. And PCs never have problems connecting to this network. -

Oct 21, 2008 5:15 PMby SRamsesIV,Wow - that was disappointing. I thought the update released today (2008-003) had finally fixed this problem. I had even composed a reply to this thread saying that it was fixed only I couldn't send it because while typing my connection dropped out! After turning AirPort off and then on again it is back to working. The correlation with starting the Windows PC doesn't seem as strong any longer but the problem is still there. -
Oct 23, 2008 5:45 AMby dd-blues,You are, of course, right. It's just that each of us can only speak about conditions they have. Since professionals are not interested i solving this problem the trouble shooting must be made by the users.
Incidentally, I have to add to my post above that I cannot be sure if it was PC computers interfering with my network or other devices attached to it. After making the post I remembered that I had connected to one of my PCs a wireless ethernet bridge. I cannot be sure, unless I do some more investigation, whether it was computers or this bridge that was interfering. In any case, after leaving only macs and a printer on my network my Mini has no longer such drastic loss of wifi signal as before.
One more thing I noticed: every time you open Airport in the menu bar with opto key pressed, the transmission rate will drop. This was in fact suggested in "help" of the AP Grapher utility. I checked and it is true (at least in Leopard). So, if there is any other process that uses wifi card, the connection may get messed up.
Perhaps we have problems because there is some running process interfering with the wifi operation. It may be coming from the router, a software etc. In any case none of my PCs or the MacBook has problems with wifi so it can be avoided. -
Oct 25, 2008 8:55 AMby Giacecco,Did any of you notice any difference after installing the AirPort Extreme Update 2008-003 fiasco and the following 004?
My MBP wireless has started again working a few days ago, before and after the upgrades. There are substantial packet losses but not to the point of killing the connection.
The behavior is so random now that I don't know what to think.
I have also noticed that keeping iStumbler running in the background (http://www.istumbler.net/) apparently prevents the connection drops to happen. I can't imagine a reason for it.
The only thing I did not try yet is going back to 10.4 , but it looks like there are people who did and did not fix much.

Oct 28, 2008 8:00 AMby macbooksad,I having the same problem, I've only at my MacBook for about 3 weeks, at first I thought there was something wrong with my router. However, I go back and forth to the beach and back to the city, both places have a wireless router. So, I finally look at my airport and it is constantly searching for networks although it was connect to the network. When I'm it is very slow because every 2 minutes or so it looks for another network. I'm taking my MacBook to apple tomorrow. But it seems that apple has no way of solving this problem and is keeping quiet.
Should I just return the computer? -
Oct 28, 2008 4:29 PMby ipoddieallovermyself,I was having similar problems dropping from the network and getting super slow speed after the macbook went to sleep and reawoke. I have a netgear dual band because of my old powerbook.
I tried most of the things in the list so i cant say this is a cure all but when i did it it worked and has been working since.
I set up my router to broadcast SSID names to reflect the band they were sending. If you keep the SSID names the same they will show up as one network in airport. If you name them for instance (network name)11G and (network name)11N you can then choose what band to connect to in airport with each computer depending on its capabilities.
This seemed to solve the problem for now? It does seem to take longer than normal to connect to the network but I have done 4-5 sleep power offs and the macbook is still getting 11207KBPS across country on speakeasy speedtest.
