I have a 486 which runs as a router, and I want to change to 2.4. After boot and working out which order the ether cards are now found in, everything is OK except I can't ping PCs connected to a 3com switch, which connects to a ne2k-pci RTL-8029 card in the 486 via a hub. PCs directly connected to the hub ping OK.
Does this ring any bells as to why this could be OK with a 2.2.13 kernel but broken with 2.4.17?might be related to ECN (just a guess). Have a look at this:

Well that fixed it. Many thanks I'd never have found that. Yours
