SonicWall TZ205 keeps disconnecting
Just recently my sonicwall started disconnecting from the internet and i can't find what is causing it. The SonicWall has a static IP and is connected to an AT&T modem. I have called AT&T and they say all is good up to their modem. The SonicWall disconnects then shows the amber light on the wrench icon. When we restart the SonicWall router it connects to the internet and runs find for about 15 minutes then crashes and needs to be restarted.
When I look at the log it has a bunch of firewall notices about and "Unhandled link-local or multicast IPv6 packet dropped." To me it sounds like a virus but can't be sure. How can I troubleshoot this issue? Where to start?
Thank you

> I am unable to upload any new firmware because the upload keeps failing
what browser were you using to upload the firmware? and the version?
some old SonicWALL firmware only works well with old versions of IE, it could make things tricky.
