Intel, this latest driver worked flawlessly for about 30 seconds. When I first installed it and rebooted, the first speedtest I did on Wireless N actually looked like a normal, sustained curve. But on the second attempt just after, on the same server, the wireless went back to the sporadic way it looked before. (Note this is the earlier image but it had this shape.)
Now, this driver actually degraded my backup, the Wifi G! When I went back to disable the wireless N as usual, the new curve looked like this.
This is what it looks like when it works (i.e the first 30 seconds after driver install, and what wireless G looked like during a speedtest before this driver):
So... it worked like this for the first minute after the driver install... then back to the normal crappy spikes/drops.
Also, when the connection is spiky(first two graphs), the ping is exceedingly high for some packets. It almost feels as if the browser freezes, then loads all at once after a few seconds.
