I'm having problems with wifi in Mint 6. I've got an Edimax EW-7108PCg PCMCIA card (rt2500 based) in my Dell Inspiron 5100 Laptop. In Mint 5 it worked fine with ndiswrapper, connecting to my WEP network.
In Mint 6, with ndiswrapper, it appears to connect perfectly -- the lights on the card show a connection, the icon in the taskbar reports a connection. But it's not actually connected -- I can't even ping the gateway at 10.0.0.2. I just get a "Network unavailable" message.
I'm currently using the default linux driver -- rt2500pci -- but it's really awful. It loses the connection about every few minutes, and takes three or four attempts to reconnect each time. When it's up, it actually seems faster than it did in Mint 5, but it's so rarely up that this is hardly useful. My Edimax card has two lights on it -- a Tx/Rx light, and a Link light. Normally the first stays steady if the signal's good, and the second stays on and flickers with network activity. With the rt2500pci driver, only the Tx/RX light comes on, it flickers sometimes, but gives no indication of whether the network's connected or not. The icon on the taskbar shows a much higher signal than is present (I live in a big house with thick walls, so there are places where the signal from the router is quite low, but the icon cheerfully shows 87% when it used to be about 56%.)
I never had any wifi problems in Mint 5, so this is intensely frustrating, especially since wifi is my only way of connecting to the net. Any help very much appreciated!
PS the link has dropped about five times while I've been writing this!
