I just got a Netgear R7000 router and installed Tomato by Shibby v130 in it. When I try to transfer large files from the attached USB HDD to my notebook over WiFi (2.4 GHz) I get extremely slow transfer rates, like 300 kB/s. Over ethernet I get 7 MB/s, so it's not a HDD speed problem. Also, running Speedtest I get the full 10 Mbps my ISP grants me even over WiFi.
The problem seems to occur only in transfers from HDD over WiFi.
Does someone have a clue?
