comment Adding WiFi connection to a desktop PC
It might have plenty of speed headroom, but does it have enough power headroom? USB 2.0 power is quite limited, is it enough for 3x3 HT40?

comment External HDD connecting via USB disconnects wireless LAN connection
@Kensai: "How is this even possible?" If both are using the same power supply, very easily. Test with a separate wireless device (a battery-powered one like a laptop or smartphone) to see if it is wireless interference or some problem (power supply or some conflict) within the computer.

comment Why does Windows 7 assume there is a new network connection when connecting to an existing access point?
I saw a Windows Vista computer do that (add a " 2" to the name and ask for the location) when I changed the wireless router (keeping the same SSID, WPA2-PSK keys, and IP addresses). I thought it was very bizarre, but since it is Windows Vista, I let it slide.

comment Wi-fi Router Neighbor-Friendly Mode?
@zharvey: 3 20MHz channels. Or 4 if you are in a place which can use channels up to 13 (they are channels 1, 5, 9, 13 - the channels have a 5MHz spacing), but some devices cannot use channels 12 and 13, so people normally use only 3 20MHz channels and space them a bit more (channels 1, 6, 11).

comment Does it make sense that the lower a router is to the floor, the worse my reception?
There are several mistakes in this answer. For instance, you CAN combine signals from multiple antennas (maximal-ratio combining), and you can transmit on all antennas without making a phased array (else 802.11n MIMO would not work as well - there is a trick to avoid making a phased array, which 802.11n uses). Oh, and reflections are good for MIMO.

comment Using UDF on a USB flash drive
@romeovs: I did not partition the drive. That is the whole point of zeroing it, to remove the partition table and old filesystem leftovers and put the UDF filesystem in the whole unpartitioned drive. Creating a partition table would only risk confusing things.
