Hi! Can everyone help me ???? I've a problem with my Ethernet-Card. The card will be recognized correctly, but it has a very slow Data-Transfer (about 10 KBytes/sec) Infos (about my laptop) (I hope they are sufficient): CPU: Mobile-Pentium II 333 MHz Chip-Set: Intel MX RAM: 64 MB HDD: 4,5 GB Fujitsu Card-Bus-Controller: O2Micro OZ6836 Ethernet-Card: Longshine LS 8534 TB-A1 10base2 or 10baseT cardctl config: ================ Socket 0:   not configured Socket 1:   Vcc 5.0V Vpp1 0.0V Vpp2 0.0V   interface type is "memory and I/O"   irq 10 [exclusive] [level]   function 0:     config base 0x0fd0       option 0x41 status 0x00 copy 0x00     io 0x0300-0x031f [auto] cardctl ident ============= Socket 0:   no product info available Socket 1:   product info: "Ethernet", "Adapter", "2.0"   manfid: 0x0149, 0xc1ab   function: 6 (network) dmesg: ====== Linux PCMCIA Card Services 3.1.15   kernel build: 2.2.15 #4 Tue May 30 15:37:59 MEST 2000   options: [pci] [cardbus] [apm] PCI routing table version 1.0 at 0xfdf00   00:03.0 -> irq 11   00:03.1 -> irq 11 Intel PCIC probe:   O2Micro OZ6836/60 rev 62 PCI-to-CardBus at slot 00:03, mem 0xe1000000     host opts [0]: [ring] [pci/way] [pci irq 11] [lat 32/176] [bus 32/34]     host opts [1]: [ring] [pci/way] [pci irq 11] [lat 32/176] [bus 35/37]     ISA irqs (default) = 3,4,7,9,10,12 PCI status changes cs: IO port probe 0x1000-0x17ff: clean. cs: IO port probe 0x0100-0x04ff: excluding 0x408-0x40f 0x4d0-0x4d7 cs: IO port probe 0x0a00-0x0aff: clean. cs: memory probe 0xa0000000-0xa0ffffff: excluding 0xa0000000-0xa00fffff eth0: NE2000 Compatible: io 0x300, irq 10, hw_addr 00:E0:98:7B:D2:A3

A few general questions: - Are you using a network cable that you know is good? (are you sure you don't have a wiring problem?) - When these slow transfers are going on, do you get any error messages from the driver in your system log? And what do the error statistics reported by "ifconfig" look like? - Does the interrupt counter for the card in /proc/interrupts run up while you are transfering data? Is the transfer rate similar for transmit and receive? -- Dave
