There was a thread about that issue on Pegasosforum.de (from Thore). On MorphOS, network-statistics shows also 10mbps, but it seems that this value is'nt the truth...... Thore reported that his PEG2 is as slow as shown, but mine (and others) connets with 100mpbs - nevertheless 10mbps is shown in statistics.....
You report now the same behaviour under OS4.....strange! I've tested speed under OpenFirmware - seems hardware is OK. MorphOS uses a stack based on AmiTCP - maybe Roadshow and AmiTCP have the same issues (seems it depends to device....). But the strange thing: why are'nt all PEG2 affected....? (Depending on board-revision.........?)
