CLEAR Net Tempest

Hi All, Has anyone else had any problems with Clear's 802.11 wireless internet service (http://www.clear.net.nz/services/tempest.html) as a source of interference? They have just done a rollout in Rotorua and totally stoped 3 separate wireless networks that had been running together nicely for the past year or two. Clear have told me that Rotorua is the only place that this has happened in and are being very slow to do anything about it so if this has happened to you could you let me know.
