l have a Linksys wrk54g model which l used till recently with a linksy notebook adapter card in my toshiba laptop. Anyway the toshiba laptop had a motherboard fault so l bought a new packard bell laptop which has wireless enabled so l dont have to use the adapter card anymore. The problem is the linksys router picks up the wireless laptop but after so long it loses or says limited connectivety and a yellow tri-angle next to the wireless icon in taskbar, this even says this when it says l have a good signal :no: .Everytime this happens and it will happen everytime l shut down and start up again l have to switch the modem and router off and back on to get a signal. This never use to happen on the toshiba laptop.What could be the problem and how to sort it out please.. :hmmm:
Could be a power saving option on the laptop to disable WiFi after so much time without internet traffic as to conserve battery life. What OS are you running?
