Phone freezes when I connect my laptop to wifi router - never did this before

[jfbk2009]

I've been using wmwifirouter for months with no problem and then suddenly, about 2 days ago, my phone freezes up completely as soon as I connect my laptop to the wifi router. The wifi router seems to be working fine before I connect the laptop. Once I take my laptop off the phone's wifi network, the phone unfreezes and the router appears to be running like normal.

I downloaded HTC wifi router and tried it but it does the same exact thing.

Any ideas? I can't think of any changes I've made to the phone at all in the last few weeks.
