Same problem here but with WiFi from a Netgear DGND3700. Lion has had WiFi issues roughly as follows, on my 2010 iMac:
10.6.8 Snow Leopard - excellent
10.7 Lion - poor WiFi
10.7.1 Lion - poor WiFi
10.7.2 Lion - fixed WiFi
10.7.3 Lion - back to no WiFi following wakeup from sleep
On past history this thread could grow as users update to 10.7.3. I am hoping for a fix and it could be that we have to wait for 10.7.4!

Well, I've just reset my TC Router to its default settings and, for the moment, my Time Capsule seems dead !
Upon restart, I get the green light for a second or two and then the steady yellow light for about 50 seconds (which I find normal).
But instead of getting the steady green light afterwards (at which point the WiFi connection normally gets alive), I get that yellow flashing light that will keep on flashing forever.
I've then tried hard resetting with a pencil at the tiny recessed knob at the rear of my TC, and the problen remains: the boot process still ends up with the same flashing yellow light.
Disconnecting / Reconnecting the Wan Ethernet cable didn't help neither.
Luckily, I have an old D-Link WiFi Router on hand. That's how I'm now back on the Internet to find a solution.
Any suggestion ?

sure... how did you reset your TC? did you use a hard reset or a soft reset? If the soft reset does not work try the hard reset... dont forget it takes a moment to write the infomation change inside the router. let me know, I am availabe.

Not a fix - a workaround requiring a download of SleepWatcher and dabbling with the Terminal:
Expand your download to the desktop.
Read the instructions.
Step by step:
Open Terminal and for a first time installation.
sudo mkdir -p /usr/local/sbin /usr/local/share/man/man8
sudo cp ~/Desktop/sleepwatcher_2.2/sleepwatcher /usr/local/sbin
sudo cp ~/Desktop/sleepwatcher_2.2/sleepwatcher.8 /usr/local/share/man/man8
echo '#!/bin/sh' >~/.sleep
echo '/usr/sbin/networksetup -setairportpower en1 off' >>~/.sleep
chmod +x ~/.sleep
echo '#!/bin/sh' >~/.wakeup
echo '/usr/sbin/networksetup -setairportpower en1 off' >>~/.wakeup
echo '/usr/sbin/networksetup -setairportpower en1 on' >>~/.wakeup
chmod +x ~/.wakeup
cp ~/Desktop/sleepwatcher_2.2/config/de.bernhard-baehr.sleepwatcher-20compatibilit y-localuser.plist ~/Library/LaunchAgents/de.bernhard-baehr.sleepwatcher.plist
Posting may screwup the syntax so be careful and the last cp is all one line with a space between ...plist ~/Library...
Restart your machine to have the LaunchAgent do its thing. Your WiFi should restart after sleep - always.

Dave - thanks for your detailed response. There is developing news about the 10.7.3 "software update" download causing problems beyond this wifi one we are discussing here.
I think I am going to wait a bit before diving into the terminal workaround you outlined. Every so often Apple simply blows these Airport updates and it takes some time for them to set things right.

This problem is only impacting one of our Macs as previously mentioned. So I wonder if the issue is related to 10.7.3 or AU 6.0 or something wonky with the install on our i5 iMac or .........?

Well - I decided to load the 10.7.3 COMBO over the "software update" to 10.7.3 I did yesterday - problem appears to be resolved - wifi connects from sleep after the combo download :-)

Well I installed via the software update. Thought all issues fixed but no.
When my imac wakes from sleep the network box is greyed and says no network. If I tick the remember net work box it connects but if it sleeps the same thing, or if I switch user or open the network box and and click my network it works.
How long has the world and their wife been trying to resolve this problem?
Should i install 10.7.3 again through the combo update?
Come on Apple this is pretty basic stuff, even my PC has never ever had this problem with any version of windows!
