    I've been fighting this issue for a few days and I'm starting to wonder if their is something wrong.

    I use an AirPort Extreme which is connected by Cat5 to my iMac and of course WiFi to my Macbook.

    Problem is that my Macbook displays a wide array of weird things in relation to the WiFi. At it's best it will connect without issue, browse ok but say if I go over the network to play a video off of my iMac, it will hesitate and skip at random intervals. During this time if I run an constant ping to the router I see random jumps in latency sometimes at the same time as the video skips.

    I can run for awhile in the condition above and then it can turn for the worst even going so bad that I loose all connectivity even though it says I'm still connected to the AirPort with a full signal.

    Sometimes if I'm trying to recover from the above problem I've had the MacBook list no WiFi networks available. I've had it show networks available but tells me I can not connect to the router when I try, etc.

    On the flip side, my iPhone and my previous laptop (an HP running Ubuntu 7.10) connects fine and with the HP laptop I can watch the same videos that hang on the Macbook with no issue, perfectly smooth.

    The Macbook is the new SR 2.0 laptop running Leopard. I've also tried a complete erase and reinstall of Leopard with no change to the problem. I would try going back to Tiger but I can't on this sysetm since it came with Leopard.

    Any tips?

    EDIT: I forgot to add that I've also hooked up my Linksys 45g router with the same hesistation problems I described above so it shouldn't be the router. I have tried changing channels on the router though, also changed from WAP2 to no secure encryption, robust connection, etc. No change on any of it.

    Same system, same problem here. I've switched routers without effect. Out of the box, it was constantly slow, maxing at 400 kbps download speed, even while plugged directly to the modem. I found some threads here about changing the DNS servers to the servers. That actually fixed the issue for about 10 minutes, then it reverted to it's max 300-400 kbps speed.

    Occasionally it will go up to full speed again. If I am enjoying full speed and restart the computer, it will usually revert to slow speed. I can't figure it out, neither can apple care or the Genius Bar. I only have a few days left before my exchange period ends, and I'm leaning toward taking this dog back. I have old, slow, spyware-laden PCs on my network that are smoking my brand new's sad. I believe the DNS server issue is the fundamental problem for most people, but for some reason it has only solved it partially/intermittently for me.

    2.0GHz MacBook Wireless / wifi problems

    I've got a 2.0GHz MacBook C2D. I'm experiencing intermittent wireless connectivity issues with my Airport Router. I struggle trying to join the network, sometimes it pops up the password screen, even though it has the password in the key chain.

    When I reboot I can get right into the network. I think I remember having the issue under an earlier version of 10.4. I'm wondering if there was a patch that wasn't incorporated into the 10.5 baseline.

    Does anyone have any info? I love 10.5, but I'm not sure I can tolerate the unpredictable nature of WiFi running 10.5.

    New Macbook

    I recently switched to a Apple with a new MacBook purchase. I am also experiencing the same lags and drops with the airport wifi. I returned my first MacBook yesterday for another but the lag continues. This seems to be a common problem with other mac users so I'm at odds to returning again...
