Ad hoc network issues?

[Advantageinv]

Is anyone else having issues connecting to ad hoc wifi since ICS update?
Prior to the update, I had been able to tether to my phone (ad hoc) but since the tab went ICS, it will not connect to ad hoc networks.

Is there a setting in there that I have missed and need to enable?

I have not had any trouble bluetooth tethering my phone to my tablet using PdaNet Tablet. It actually works much better with ICS than it did with Honeycomb.
