I have had this issue since brining my EVO home 2 months ago. I turn on wifi and connect to my home network with no problems. After random amount of time I lose internet (anywhere from 10 minutes to an hour). Everything connected to my wireless router loses internet (hardwired and wireless). Wireless signal stays connected to all devices, just no internet. Pull the plug on the wireless router and do a hard reset and internet comes back on. I am positive my EVO is the cause, as this problem only happens when I turn the wifi on. Any ideas on what to look for?
