When using ES File explorer, I get around 7.5Mbps (Notebook on wired LAN, transformer on Wi-fi)
For speedtest.net I get is 7Mbps, but my notebook clocks 13Mbps over wi-fi.
I don't have another computer with me right now, therefore no way to test PC to PC wireless speed (one on wired, other on wireless). But from the looks of it, transformer is at least 2x slower than my notebook according to speedtest results; but since my ADSL connection max outs at 13Mbps anyways (even over a wired connection), I'm pretty sure that is far lower than the maximum achievable speed with my router. I was expecting speeds in the range of 20Mbps +.
What speeds are you guys getting ?
P.S: Transformer detects the link speed as 54Mbps, all speeds listed above are in Mega Bits Per Second.
