Boosting laptop wifi broadcast signal

[moiety]

I just found this out today. There's been a few occasions -mostly when trying for some free wifi- when the signal has been banging in at 3 bars out of 5; but I can't connect. It turns out that manufacturers turn the wifi broadcast power down out of the box; because it helps battery time and looks better in the sales figures.

So in Device Manager; Network Adapters; Your WiFi adapter...right click on the adapter, and select Properties. Varies from machine to machine, apparently, but I found mine under Power Management...and sure enough, it was turned right down.

You might find this handy. Useful to know, anyway.

For Wi-Fi cards and other networking devices I always disable the power saving settings on those. Nothing good with those besides degrading quality of service at times, or saving 5 minutes of battery power if that. You're better off getting battery life by lowing the core voltage of the CPU and GPU and/or lowering the screen brightness.
