I use a a Buffalo AirStation B/G/A wireless card in my TiBook. It's been having a lot of problems lately, especially today. Today it has dropped connection to my router entirely about 5-6 times at least (It doesn't even see the router until I try reconnecting several times). Sometimes, when I plug it in, my mouse pointer freezes and I have to eject it and keep reinserting it several times to get it to actually work. And if I don't take it out before booting the laptop, it prevents it from booting (I get the start up sound, but then the screen stays black), and if I leave it in and my Powerbook goes to sleep, it refuses to wake from sleep. I've had it for too long to ask the website I got it from for an exchange, but I'm about to take it out and throw it around my room because it's just aggravating me that much.
I know it's well within range of my router, as it's in the same area where I used to use my iBook, and my AirPort Extreme never had any major problems.
I need a fix that's going to make this more stable without costing me a lot of money. Any help would be appreciated, because I really want to just have more than a 12 hour period per week of actual smooth running.
