That was a suggestion which was offered in a previous thread on this topic, some time ago. We tried it, but it didn't resolve the issue, in our case.

I think that the fact that there seems to be multiple fixes suggests the possiblity that this is not a single problem, but rather, a constellation of problems which share the same symptoms.

In the case of our business usage of the 8800, we are not dependent upon the data connection for our priority needs. So, if the battery pull doesn't solve the problem, then we know the problem will resolve all by itself, in a few hours.
