I have an R13, and while I love it, the Wifi connection has been rather poor, to the point of where using it for remote desktop into my work is very hard.
Here's what I tested so far:
Running a ping on both the R13 and my Windows machine, same Wifi network and frequency, same time, same IP pinged, there is a vast difference in ping times, with the Windows machine being very consistently low, the R13 all over the place, almost always significantly higher.
Even more telling, pinging my router gives a consistent <1ms on the Windows machine, between 5-10ms on the R13.
I tried this on a different Wifi network to make sure it's not a function of the network (no difference), and I powerwashed the R13 (no difference).
What kind of ping times are you guys getting to things like your Wifi router? I feel this type of variation can't be right, and since I'm still inside warranty I wonder whether I should have it exchanged.
