Downstairs PC, Win XP Pro. Hooked directly to Speedstream 6520 Modem. Internet works perfectly. Upstairs PC running wirelessly off downstairs PC. Has Win XP Pro. Works perfectly. Downstairs is the host. One folder is shared, as is the printer. Upstairs computer does not see the printer or folder. I've tried a number of times and no luck. I followed online setup instructions, and nothing. Before my last wipe/reinstall of XP, it printed and accessed the folder without issues. Upstairs ping of downstairs computer: Any ideas?
