I just upgraded the firmware for my SMC7004FW router to fix VOIP problems (cutting in & out ). However, I cannot connect with certain websites and have intermittent problems with other. I get the message "resolving host www.xxx.xxx
" in the status window followed by the error message "www.xxx.xxx
could not be found. Please check the name and try again." I'm also unable to open multiple tabs simultaneously in Mozilla Firefox, which I could do before. I believe I get the message that the browser cannot find the url or sometimes that access has been denied.
I've tried reloading the firmware upgrade to the router, reseting the router, and releasing and renewing it. Still have problems. I've also repaired the connection on my local computer multiple times. The computer is now plugged directly into the SMC router, rather than being routed through my MegaFast switch. Also, I tried connecting my computer directly to the broadband modem, and all the problems disappeared. But once I re-connected through the router, the problems came back. I had none of the problems before the firmware update (although the VOIP quality is improved). FYI, I'm using Comcast.
