Hello, I have just migrated to the Linux kernel version 2.4.20 on my old Dell Latitude CPi A, and am experiencing problems with networking through the PCMCIA ethernet adapter, a 3Comm Model 3CCFE575BT. The symptom is extremely slow throughput; for example during FTP of large files, the rate is under 20 kB/sec. Running the same transfers under Windows 2000, I get more like 10 MB/sec. Also, this card worked fine under my earlier Linux driver, which was the 3C575_CB driver in the 2.4.5 kernel. A hint could be that the transfers seem to start off rather fast, but then get slower and slower. Hoping that it's of any help in finding the problem, I enclose the output of lspci -v and dmesg. Let me know if there is anything else I can try to get more information for you. Thanks in advance for any help you can provide in figuring out what the problem might be. Regards, /Bob =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Robert E. Penny <[email protected]> Ericsson AB - UAB +46 8 727 2705
