I have a new laptop now with Ubuntu installed. The wifi at the office is much spottier than it used to be in my old computer. (It sometimes fails to connect, and sometimes drops the connection.) I'm looking for a good setting for iwconfig that would fix it. I don't know what are good parameters for each of the options in iwconfig...
I'm aware that switching off my wifi power management would solve the problem, but I would prefer not to do that.
