I am not sure if it is only since the upgrade to 10.4.10 but I have noticed recently that my wireless network performance when running on battery power is absolutely awful - when browsing and clicking links it just hangs for ages. If I grab the power cable and plug it in its fine so its not my router or the wireless network itself. I have the power settings set at Better Performance when on battery to see if that made any difference but nothing. Anyone have any suggestions as to what I can try to sort this? Its driving me nuts and effectively makes wireless networking pointless as I have to be plugged into the mains.
