Thats a problem we've had... there's a way around it... go to the linksys site, grab the firmware upgrade for the router and then upgrade it via the router settings page... (it's all pretty easy enough to do) but I found out with this particular flava of router that it does do this kind of thing... and the only cure we know of, is to keep reinstalling the firmware upgrade. As I am aware, there are no more upgrades for this particular model router and although it's a PITA, it's something we've come to terms with... well worth the 5 minute wait while the firmware upgrade does its thing.
We too were at the point of going absolutely mental with it... we were close to buying a new router until I did the necessary......
Trust me.. firmware upgrade is the answer to your problem and your envisioned hair loss will be no more
