problem in throughput to internet

hi !

my problem is as follows. My Service Provider gives me 40 Mbps Internet Connection (dedicated), the topology is connected as follows:

(ISP CPE) --- (CPE Customer) ------ (SWITCH 2960) ------- (LAN Customer)

When I connect directly to the customer router, I get 40 Mbps, but when I connect to the switch, I only get 3 Mbps to internet, in any of its interfaces.

IOS has is c2960-lanlitek9-mz.122-50.SE5.bin, all interfaces are forced to 100 full duplex, and an interface is in trunk mode to connect to the router of the customer.

It may be a problem in the IOS?,I suggest you check on the switch to detect the fault?

attached configuration file

thank everyone for their contribution

Wrong forum, post in "LAn and switching". You can move your posting with the Actions panel on the right.

Can you show config of the customer router?

Try to connect link from router to another port on the Catalyst. Don't forget reconfigure this link to the trunk. Also give us output of "show interface Gig0/1" command

where Gig0/1 is trunk to the router.

How did you connect directly to the customer router? Did you use PC with tagged interface?

And check ethernet cables

I tested with another switch and is operating correctly. Only I need to know because the other switch does not work with the proper performance
