Errors on 2511

I have a 2511 and it is connected to a 3com 10baset 8 port hub and i am getting E0 input/output errors. Can I configure the speed/duplex on the router? Also, from the sh ver. output my image file is flash:igs-i-l.111-6". I can't find any documentation on that image.

I can not find specific information on that image but was able to find these docs on 11.1 software:

Make sure the duplex settings follow these guidelines to reduce issues with autonegotiation:

A. NIC set to 10Mbps/half-duplex, switch set for auto.

Result: The switch can detect the NLP from the NIC and sets itself for 10Mbps and with no auto-negotiation (FLP) from the NIC, the switch defaults to half-duplex. A valid combination results, but only if the switch's default duplex matches the NIC setting.

B. NIC set to 10Mbps/half-duplex, switch set for 100Mbps/half-duplex.

Result: No link. Neither side will establish a link to an incorrect manual speed configuration. Auto-negotiation has been disabled on both link partners by manually configuring them.

C. NIC set auto, switch set for 10Mbps/half-duplex.

Result: Link is established in a valid configuration. The NIC sees the NLP from the switch and sets itself for 10Mbps and with no auto-negotiation (FLP) from the switch, the NIC defaults to half-duplex. A valid combination results, but only if the NIC's default duplex matches the switch settings.

Use the full-duplex and the half-duplex commands to change the transmission mode under the interface.
