Thread: discovery issue when using as a wifi router

has anyone any ideas what may be going on, i have the app that makes my htc touch hd into a wifi router,, great it worked once, able to connect the lappie easily, well that was yesterday , for some reason .. now i cant get neiither my laptop or desktop to discover the mobile , they pick up other wireless networks but not the touch hd? im guessing it must be something with the phone.. any ideas, ive googled this and have found the same question but never an answer
