OT: Wireless help

[lcjjdnh]

So, I'm having a little trouble with wireless at my house and was wondering if any tech gurus here could help me out.

The facts:

-- I'm having no problems with the wireless on my computer (Toshiba) other than at my house
-- Neither of my roommates (who both have Macs) are having problems at my house
-- When the wireless does work, it says it's not connected, even though it is
-- Wireless will only stay connected a few minutes at a time
-- The only way it will reconnect is when I re-enter the password
-- Sometimes, the settings change and says password will be provided, when I haven't touched anything.

I can give more details if needed. Any help would be appreciated.
