I have a couple of the gwn7711p out here and there, great little switches and nice that I can remotely reboot. I have one that keeps blocking print jobs even though I can ping the printer. As soon as I reboot it, print jobs start working. I have one at another location that will prevent the computers hooked up it from logging into a domain controller, once again reboot and all good. Firmware is up to date. I opened a ticket with GS support but was interested if anyone else has seen this. Thanks
