I just returned my WRT54G and exchanged it for the same on the\nsalesman's reccomendation. This second one has the same problem as\nthe first. After setting it all up and enabling WPA it works for\nabout five minutes. Then, although the wireless connection on the PC\nreports a strong connection to the router, it cannot access the\ninternet.\n\nI have a Linksys WMP54G PCI card in the computer.\n\nIf I was doing something wrong it wouldn't work at all, would it?\nThat's what is baffling me. That it works great for a little while,\nalways about five minutes, and then after that there is nothing I can\ndo to get it to work again except shut it all down and go back to it\nlater on.\n\nIs this a common problem with this model?
