cisco 1751 is doing half duplex instead of full
cisco 1751 router
one 10mb nic set to full duplex
one 100mb nic set to full duplex
hooked to a trendnet smart switch, the switch port where the cisco hooks immediately goes to 10mb half. If I try to change it to 10 full, it responds that the cisco is only doing half and the port must also do half.
the connection going out the other port goes to the our wan which is full.
why is the cisco doing half even though it is set to full?

these cards are nockoffs.
1. they have copper solder points, cisco uses only silver
2. were there should be one electrical part there are two
3. the port is not cisco standard
4. the writing on the cards does not fit in spaces aloted, and is on, not part of the board
5. serial number are printed wrong
6. words on chips are stamped on not etched as they should be
they will not do duplex and they cause extreme packet loss.
to conclude they are second rate junk, and from what I am hearing any cisco or any other card listed on Ebay from China or Hong kong are fakes.
after we tried to use these cards and had major problems with our network, we started looking on the web for info on fake cisco equipment.
check this site out.

bought an authentic cisco card to compare these with and one can see the problems with the cards immediately.
put the authentic cisco card into service, network problems went away!
any one reading this needs to spread the word about not buying Chinese cards sold on ebay.
live and learn I guess

I added a 10mb wic 1enet which will do full
I found out the the telco had set our line to half because the router we had in there was a 1600 and only did half.
I called them and they went to full
The problem is that only one of my 6 offices on this private telco network will the smart switch report that the cisco 1750 is talking to it at full duplex.
so what it appears is that the telco side is full and my side is half, and it appears for no reason.
all interfaces are set to full duplex on the router
