I recently setup a LAN between two comps at a friend's house using an SMC1211TX card (came with one comp) and a new Realtek RTL8139 with a crossover CAT5 cable. The network allows access as it should and performs in LAN games adequately (showing 0 ping!), but transferring files is unbearably slow (about the same speed as a 26.4 modem connection.) What can I do to get this working right? I'll be happy to list more detailed network specs as needed.
