Query: Firmware on this box is buggy

It would be nice if it did what it said on the tin but we found that this box couldn't stay up for more than a week before hanging and requiring a power cycle to get going again. 3Com gave us a patch to fix the bug which totally wrecked the thing and took out the onboard webserver required to manage it. We're replacing it with something else. Do not buy this product.
