Wifi suddenly stopped working

I just got my Motorola Droid this week, and I've been having a few issues.

I bought the phone pre-flashed to Cricket, but the flash wasn't done correctly. Everything on the phone worked except the 3G and the picture messaging. WiFi, calls, texts, and everything else was great.

So today I got the phone properly flashed. Now 3G and picture messaging work fine.

And WiFI was working fine for about a half hour. Then it suddenly stopped, and I can't get it to work anymore. I tried resetting the phone, resetting the router, clearing my cache, etc.

The phone says I'm connected, but it won't run any internet-based apps or let me browse the web.

I have disabled security, told the Droid to forget the network, refreshed my settings, etc.

Nothing has helped so far.

What could make it stop working so suddenly? It had been working perfectly, both pre and post flash. And then it just decided not to.

The router is known to be functioning properly, as my netbook and Nintendo DSi are connecting and loading content without issue.
I had this problem, I called the cable company and they sent a signal to reset the modem and gthen it worked.
Why would that make a difference if only the Droid isn't working? The modem is working fine, because all my other devices are online.
Yesterday, after owning my Bionic more than a month, the wifi stopped working. Connected, ip address, but no throughput. I updated to 5.7.893, but that didn't change anything. If I forget then re-add the AP everything works for about 60 seconds, but you can watch the connection degrade very quickly. All of my other wifi devices work flawlessly, including my original Droid (with CM 7) and my Asus Transformer. I tried resetting the router (factory reset) anyway, but no luck.

I ran a shell session to poke around to see if I could narrow it down to DNS or something else, and I couldn't really find anything. Look at this output from a ping of my router, and notice that there are missing packets all over the place:

shell@cdma_targa:/$ ping -c 20
ping -c 20

And then this output pinging another computer on my network:

Then this output from an nslookup that takes 11seconds to return for Google...

I had this same problem with my original Droid until I installed Cyanogenmod. Is this just an ongoing issue with Android? I have seen lots of people talking about variations of the same issue with different phones, especially when I was trying to resolve this on my old Droid.
I have had my bionic for about a month also and I have not had any issues with 3g / 4g / wifi/ the real only issue u have is camera lag and if it doesn't get fixed with the next upgrade coming by the end of the year then I will pass the problem onto my dad and use his upgrade to get a razr.
