I'm switching over to wifi for my older laptop and have problems with dropped connections intermittently at one end of the house using a usb dongle. I suspect its also when the neighbours' are also on their wifi pc's. Another laptop with a built in antenna works just fine. I used netstumbler/netview to look at the surrounding wifi networks and the channel is set appropriately. Some researching seems to suggest that pci-cards are better than usb adapters in terms of signal strength and having the advantage of "hardware connect" (whatever that means). http://www.tomshardware.com/forum/174476-28-wifi So are pci adapters still better than usb? Is that because of the bigger external antenna? There are usb adapters which also have antennas - eg. http://www.newegg.com/Product/Produc...82E16833704045 (4dBi gain). Or are the differences now moot because of advances in tech?
