i recently purchased a wrv200 wireless router. all was working well, everything was set up ok. then one day my pci network card couldnt find my router. it connects through the wire ok, but doesnt show up on wireless. i can find other routers around my street, but cant see mine. also im sure that when it was working the wireless light was solid green, but now its flickering. i cant be sure either way. but is this normal? ive tried pressing and holding the reset button for 30 secs and it still doesnt find it. my wireless pci cards are WMP54G and the wireless router is WRV200 anyone have any ideas?
