I have a N810 WiMax unit and having some problems with it logging on to WiMax (Wifi works). I can surf the web via WiMax but I am not able to use instant messaging or internet calls, I have my accounts set correctly (they connect with Wifi). Also the WiMax icon in the toolbar flashes and the Presence icon stays red. Xohm tech help can´t seem to find an answer. Have you any tips? thanks
