CISCO 2921 to Level3 Fast E, download speed is low

bc4switch
Level 1
Level 1

Our ISP is Level3 and we have 100Mpbs Fast E line.

However, with various speed testing tools, we never got better that 20Mbps download speed.

Upload speed is usually better than download speed.

Also, using Level3 suggested testing tool: testmy.net, upload is almost 4 times faster that download speed.

Per Level3, we hard code our router interface speed to 100, duplex to full.

Appreciate any opinions or past experiences.
