All problems related to drivers

WHen you install the XP, it may not have the drivers for your hardware. You need to download from the hardware manufacturers, and usually they are free.
For problems:
(1) You need the driver for the TV tuner
(2) You need the driver for the wireless addapter
(3) You need the driver for the modem
And (4) it depends where you live. In terms of speed, Optical fiver (like Verizon Fios) is the fastest, and then cables, and DSL is the slowest among them. In terms of the service quality, you need to ask you neighbors to compare.
