Wireless signal strength increases when connected

post #1 of 5
Thread Starter 
Say for example Windows shows the signal as 3 bars but once I connect it becomes 5 bars (sometimes 4), why does this happen? I've noticed this every single time with different wireless networks.
Just curious. smile.gif

Depends on the network. The signal "seen" is just enough for the client to see the network. Once connected the router can establish a full signal.
On my network meter it actually looks more like a "ping" or spike in signal every few seconds or so, so windows is probably just showing the average of the broadcast signal.

It's the router's doing to save power wink.gif Don't you love it when routers attempt to save power?

Usually when you're scanning for access points, your NIC is jumping between channels looking for APs. A brief snapshot from a beacon on that AP may not show the most accurate/average data or may be received on a bleedover channel instead of the intended one (spread spectrum spans your signal out which will give you a 2 channel range in either direction that your data overlaps onto).
