4 T1 slow upload, file corruption download

Hello Experts,

I have 4 T1's connected to my cisco 2800.

I'm having problems uploading. It only gives me 3megs when it should be 5.5.

My downloads get corrupted when they are over 200Mbps in size.

I have been reading a lot, and I can't find the answer. Only thing close is this command:

(config)int multilink

(config-if)#bandwidth 6056

Will this work? I understand that the bandwidth command is only for routing protocols and not related to the actual bandwidth.

I'm attaching the config, show version, show interfaces.

* Very important note, the ISP brought another router (not Cisco Brand) and everything worked perfectly, so it definetely is the router.

Thank you,

From first looks, you have a lot of CRC errors on your Serial interfaces. You may want to hard-code the speed and duplex for these lines. This will slow your speed down tremendously. The second is that I see "ip nat outside" on your multilink interface, but I don't see a corresponding "ip nat inside" on any of the interfaces. I'm not sure if this would cause the problem you're experiencing, I would suspect the CRC errors more than anything.

Did you post a complete config?
