Hi, My WRT54G-tm with raf outperforms wnr3500L with raf or dd-wrt k2.6. I am hitting a fraction of the old wifi speed with the n setup. I have 2 wired pcs and they seem to be fine, the problem is with the wireless setup. Two laptops without native N card and ipod touch 4 with N support (not sure if 150 or 300 capable). 1 laptop has xp, g card disabled and the other has win 7 with g card disabled. Both have belkin N usb adapters model F7D2101 v1. Ipod has much faster connection than the two laptops but still not as fast as I had with good old G. My tomato/dd-wrt setings - N only, 40mhz, wpa2-aes. Tried all sorts of possibilities including 20mhz, auto channel. Read that lowering pawa from 75 to 20-30 might help, didn't have time to test it yet. What can I do to troubleshoot it?
