Swapped out switch and firewall, still our internet goes down, Any ideas?

By sudima25 ·
Our internet goes down at least 2-3 times a week. ISP has no problems and can ping our switch, but we can't get access. We then have to manually reboot switch and firewall and everything is back to normal until the next fail. Any thoughts?

We swapped out old switch and firewall and now are running a Cisco switch and SonicWall firewall. Thank you.

Have you got any Filtering on the Switch & Firewall?

Power Spikes can cause this to happen and if you fit a Filtering UPS it stops it from happening.

What operating system do you run?

Does this happen to one computer or do you have many?
Go to your onboard nic and do a update, if possible update it to another nic software/hardware.
Another way is to get a NIC card and try that. It could be that your onboard nic is failing.
