But I'm only # getting the same rates as I was using just the crossover. Might I note that transferring from one (slow) laptop drive to another (slow) laptop drive will never be Fast(tm).. this is just my opinion, I guess.. but they aren't usually capable of a lot of throughput, certainly not enough to really utilize a 100mbit LAN connection.. why would a switch make any difference except speed auto-negotiation.. No, I REALLY don't believe a crossover cable is "limited" to 10mbit, I think you may just need to explicitly set each card on each end of that cable to use 100mbit ONLY.. don't let it auto-negotiate, that may be your problem.. but as I also noted, you may not see a lot of an improvement from HDD->HDD .. that's most of your bottleneck. # I've got 3 straight through twisted pair CAT5 cables, the Linksys PCM100 # Etherfast PC card, my old Xicom combo modem/LAN card, and a generic # 'Network Anywhere" card in the desktop. Xircom? 10/100 or just 10mbit? .. how fast is the "Network Anywhere"; also unfamiliar with that.. # I tested the same transfer from L100 to L70 through the LAN switch with # combinations of the 3 cables. I tried the same transfer from the L100 with # the Linksys card to the desktop with combinations of the cables # # All transfers actually turned out to be a tad slowed than using the # crossover cable. All rates averaged 4.7Mbits/sec. Think about it, add anything in the middle of your connection, how could it possibly make it faster? you're adding distance, latency, more processing time.. etc. # I've also been on live online support with Linksys, and can't determine if # the middle LED for 10/100 on the PCM100 Etherfast NIC is supposed to switch # from yellow to green connected at 100Mbps. All they can tell me is when # the light is 'on', it's connected at 100. But it's been on, and yellow for # all my transfers using the crossover cable. Anyone know if that 10/100 LED # is supposed to change from yellow to green to indicate either a 10 or 100 # connection? No ideas about this specific card.. I'm throwing out general ideas here, they may be of more use to you than tech support for your hardware, which sounds like it is functioning fine, as far as discontinued old laptops go ;) (I still love my libretto.) - Jonathan Towne ************************************************************** http://libretto.basiclink.com - Libretto mailing list http://www.silverace.com/libretto/ - Archives -------TO UNSUBSCRIBE------- Reply to any of the list messages.
