I am attempting an 802.11b lan install, I have a dlink wireless router that is working on the wired lan and seems to be sending out a signal, on the system needing the wirless I have a dlink wirless PCI card and roughly between the two I have a Dlink wireless repeater. My system picks up a very strong signal (90% sig strength 90% sig quality) for about 5 min then every thing drops to 0% and connection is lost, if I fiddel with the antena connection comes back ocasionaly other times the sig takes hours to come back. Any ideas?
