I upgraded my wireless network to N and I got a internal Linksys PCI wireless card for sale. Its the GS series with Speed Booster , WMP54GS. Will work with B/G/GS/N routers , with a N router you will only get G speeds. I've had it for less then a year , I paid $79.00 for it and I am asking $30.00 , $20 for the card and $10 to ship it properly. You send me $30.00 cash in the snail mail , I send you the card the same day. In private message I will give you my home phone number to seal the deal voice.
Performance :
Ive had no problems with this card connecting to wireless networks or installing. Its about 30 feet from my router and I get "Good" signal strength according to Windows XP Zero Wireless Configuration.
This cards works on Mac OSX Leopard 10.5.* with -
NO - user interactions , plug it in , Leopard recognizes , installs the drivers and finds/joins open networks automatically.
Works with Vista , personally tried , auto installs drivers , joins networks no problems.
Works with Linux , personally tried , took alittle tweaking with set up and driver install but got it working 100% with Ubuntu Linux.
I am a hardcore gamer and I don't have any problems with lag or studdering during online gaming sessions.
