I have an SG220-26P, i have had I for a while now and it has always worked with no problem, after an office move all server and networking equipment was virtualized for the time being and now that we are bringing things back on site the switch seems to be the only weak link. The switch works fine for connections on the network but will only allow internet access for a few seconds at a time before becoming completely unusable. I have factory reset the switch and reconfigured it with no success. I have also confirmed that the issue is only present when the switch is being used as a direct connection to the router works just fine. Any help is appreciated thanks in advanced.SG220-26P
