I have an old computer (P1, 32MB, Win98, Winamp, Realtek8139 ethernet card) that plays mp3 files from another computer (up-to-date laptop) without interruption, but only when that other computer is connected wireless to the router (WRT54G). When the other computer is connected to the WRT54G with ethernet cable, the mp3 files have dropouts every 5 seconds. I also get the same frequency of dropouts when the old computer is connected to a desktop computer (wired). Note: Everything works fine into the other direction. Router firmware: Both with Linksys 4.20 and Hyperwrt-Thibor-15c It does not matter if the other computer is running Windows or Linux, in both cases wireless works and wired does not. I expected wireless connections always to be slower and less reliable than wired. So I think that there is a hardware problem in WRT54G. What could be the reason and, more important, what could be the solution?
