Since upgrading my Fall 2009 21.5" iMac to Lion my wifi connection will drop out about every minute and the I have to turn Wifi off and then back on to get it to connect again. Is there any known way to fix this? Any suggestions will be appreciated
Thanks

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.
Get a grip.

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.
Has anyone attempted to upgrade to 10.7.1 yet?
It claims that one of the things that it fixs is wifi dropping.

I didn't have WiFi issues until AFTER installing the 10.7.1 update.

I did the 10.7.1 update tonight. It is a 55 MB download and installed without an issue. It appears to have fixed the wifi issue I was having, which was frequent disconnects when using 802.11b and/or long beacon intervals. I did a workaround (changing the access point to 802.11g and a 50 msec beacon time) which worked for me but obviously I can't do this with every access point I use. With 10.7.1 it seems to be stable, coming back without a problem after sleep, and working OK with 802.11b. This is with a new mid 2011 MacBook Air.
Well, let me see, William Kucharski. I stated that my Internet conneciton was dropping repeatedly after installing Lion. I stated that I was able to maintain a stable connection to the Internet when, on the same computer and using the same router and the same modem, I booted into Windows XP. I also stated that I heard that Windows 7 was a good operation system.
Now, which one of those facts do you not like? I'm guessing you're a "fanboy" and an adolescent. What else could explain your obvious dicomfiture with and hostililty toward reality?
