Connection Drops . wrt150n disconnecting
This is a firmware issue with the newer Linksys routers, and most people are having the same issue. Don't expect a stable firmware release from the manufacturer any time soon.
Instead, if you want to fix the problem properly, head on over to www.dd-wrt.com and install their firmware. I did this in a last ditch effort before throwing out my router, and now the router hasn't acted up for more than 10 days.
Be sure to follow the instructions when flashing firmware, several of the steps are critical to not "bricking" your router. As usual, make sure you are on a WIRED connection, as flashing from a wireless connection is guaranteed to kill your router. When flashing dd-wrt's firmware, you must also first flash a "mini" or "micro" version before flashing the full version.
