Low Internet Upload speed

[NInja Black]

Hi,

We are receiving low internet upload speed (6-8Mps) at our office location. The download speed is good (50Mbps).

Got in contact with the ISP Comcast and tried testing it bypassing our internal n/w i.e. connecting my laptop directly to Cienna (Comcast GW)

and both speeds were around 50Mbps.

Testing the same through my router the speed goes down. Just the Upload speed.

Could there be a configuration in our router thats causing this? Moreover we have few other offices near by with the similar router config but they seem to be getting good speeds.

FYI on the internet interface thee settings are

'duplex full

speed auto'

Any insight will be highly appreciated. Thanks

Hello,

what switch platform do you have, and how are you connected to the Internet ? Post the configs of both your switch and your router...
