I recently noticed this about a week ago... I have 3 wireless clients on my WRT54G running latest thibor firmware. On ethernet port 1 i have my voip adapter [linksys voip] --(port 1)--[WRT54G wifi router] -- [cable modem] Usually everything works great. The network is fast and the phone quality is great. I have one wireless client which is my development server (I work from home). I have a laptop, my fiance has a laptop. The problem is, I would be working and then all of a sudden I wont be able to access anything (not even on my network or internet). At the same time, the phone goes dead; no dialtone. When I look at the router, i see that the WIFI light is blinking really fast AND the voip adapter light (remember, on port 1) is flashing really fast. The phone isnt being used so obviously the light shouldnt be flashing this fast (usually it's solid when not being used, slow flashing then in use). The Internet light is also flashing really fast. SOMETHING is going on here! While these lights are on, I can't access the router interface via wifi or plugged in. Also, the connection light on the voip goes off during this time too. I noticed also that while this is happening, my development server is also flashing REALLY fast on the adapter. If i disconnect that client, the problem resolves itself and the dialtone comes back. I scanned the development server multiple times for viruses; nothing. Anyone have any ideas? Thanks!
