I was wondering if it's normal for the maximum wireless speed rate to be reduced by half when the wireless radio is not in use? For example, I've installed the K2.4 build of the Shibby firmware (tomato-ND-1.28.5x-093-VPN.trx) on my Linksys WRT300N V1, and I was able to measure (and maintain) 270 Mbps according to inSSIDer. However, when I installed the K2.6 build (tomato-K26-1.28.RT-MIPSR1-093-MiniIPv6.trx) on the same router, it started as 270 Mbps max, but later on, it was reduced by half (135 MBps). The same occurrence happened when I installed the latest K2.6 build (tomato-K26USB-1.28.RT-MIPSR2-093-VPN.trx) on my WRT610N V2 router, with the difference being that the max speed is reduced to 150 MBps, instead of the proper 300 MBps. I did the proper reset (i.e., full NVRAM erase) when I install new firmware.
