My wife has a Droid Razr as well. We also just installed the update. She still cannot connect consistently to our home router. Sometimes it works, sometimes not. It will show as connected, but the WiFi signal bar is completely grey. If I check the router, I can see that it is connected. Unfortunately it does not work. I have a Samsung Galaxy SII LTE which connects and works fine on the same router. If you Google a bit, you will find that there are a lot of Droid Razr people (an other Motorola phones as well) with this same problem. Seems to be a Motorola issue. So far I have not found a way to fix it.
