    BTW - we see the same issue on SL 10.6.8 as well.  Our workaround - we run KisMAC (a WiFi Scanner) constantly to keep the WiFi connection busy and from dropping...

    I am actually nervous about the .1 release.  Just installed it, and I'm online.  Haven't been knocked off yet, but I'm on the edge of my seat waiting for the connection to die. I know that ax is going to drop any second now . . .

     

    Uh, wait.  Is this PTSD?

    Downloaded 10.7.1. Guess what? Still Wi-Fi problems. Sweet Mary Mother of God Apple get your act together....

    Same here. 10.7.1 does not fix the WiFi problems on my iMac (27-inch, Mid 2010)

    3 hours in and there are no issues for me with the update.

    Well, I upgraded to 10.7.1 and I'm still seeing the dropouts. There not quite as frequent but still occur often enough to practically cripple my internet as I have no hope of being able to use websites that require a constant, stable connection (youtube, facebook for the IM, etc.) Really not sure what my next step is as nothing posted/recommended in the forums worked and any standard warranty on my iMac is over, this update was really my last shot...Looks like I'll have to wait for 10.7.2 assuming that further addresses the issue and/or builds on whatever was done in this last update.

     

    (Just for referance well typing out this comment I've had a ping running in the terminal and I have watched it timeout about 5 times over the course of 3 minutes.)

     

    Great OS though. I mean I've always felt that wifi was just another feature that should be taken away in the ongoing quest for upmost simplicity. ...

    Your pompous attitude is not very helpful to the hundreds of people on this thread that are clearly having an issue related to their upgrade to Lion.  Did you ever consider that the way Lion handles wireless protocol negotiation might be locking up the router.  My Linksys running DD-WRT FW using WPA2-PSK hadn't been rebooted in 6 months prior to my upgrade to Lion.  Since the Lion upgrade on my 2010 iMac the wireless side of my router freezes when the iMac is coming out of sleep and reassociating to the AP. This causes all of my client devices (2 iPads, Macbook, Win 7 Laptop and Apple TV) to all lose connection to the network. The wired side of the router continues to function. I can disable WiFi on the Lion machine and the problems cease to occur. The only change that has been made to my network during this time is the upgrade to Lion.  In the future maybe you should keep your unhelpful comments to yourself.

    Guess what - if that happens, it's a firmware bug in the router.

     

    How many times do I have to reiterate that if a client can cause a router to "lock up" or otherwise stop working, it's the fault of the router?

     

    That doesn't meant Mac OS X doesn't have bugs, that doesn't mean it may not be doing things it shouldn't, but if the router locks up, it's a buggy router, period.

     

    That's not pompous, arrogant or anything other than truthful.

     

    So perhaps, just perhaps, this is a bug in DD-WRT and you should try a different router.

     

    For example, if you happen to have a revision 2.2 WRT-54GS:

    Apparently there is a bug in the WRT54GS v2.2. The bug involves a fatal memory access error due to a difference in the CPU clock speed and the clock speed on the memory bus. This bug causes connections to be dropped when transferring large files. New versions of the Linksys firmware overclock the CPU to 216 MHz. This can be fixed by logging into the router via SSH or Telnet and executing the following commands:

     

    nvram set clkfreq=216

    nvram commit

    reboot

     

    When running DD-WRT micro v23sp2 on a WRT54G v5 the clock speed can be adjusted by logging into the router via SSH or Telnet and executing the following commands:

    nvram set overclocking=216

    nvram commit

    reboot

     

    After rebooting the router you can confirm that the new clock speed has applied by checking the Status page of the DD-WRT GUI or by logging in via Telnet and executing the following:

     

    nvram get clkfreq

    I think Apple is squarely to blame if the router in question is a Time Capsule or Airport Express like mine is. There should never be an issue between two Apple products.  It should "just work".

     

    Additionally, I'm having issues with every router I come in contact with. So my experience says, it's not the router. So tone it down.

    Tone down what?  If the router has issues, it's a router bug.

     

    That goes for whether it's a D-Link, Linksys, or Apple router.

     

    I never said it didn't apply to Apple's products.

     

    If you're really having an issue with every router, take your machine into an Apple Store and see if you have issues with their in-store network.

     

    If so, it's an issue with your machine or with Lion.

     

    If not, it's elsewhere.

     

    Regardless it's a great troubleshooting technique, though obviously much easier if you have a MacBook of some type rather than an iMac or Mac Pro.

    Tone down your attacking and arrogant tone.  There's no need for it.  People are frustrated with a product that used to work and since upgrading, doesn't.  So cut them some slack.  Not everyone is so well versed as you.
