Please post your full router stats. Full router stats are key to any speed & connection issues.
Stats from any router will do. They're all much the same. It's not the logs but something like Connection Status, I seem to remember Netgears calling it. It'll have the word "Attenuation" in it.
What is this router you are using? Is it 1 device? Not aware of a Linksys/Netgear/CISCO hybrid.
