    hi everyone!

    i have a question about the wireless speed i get when both the 2.4GHz and 5GHz are enabled on my Asus RT-N66U router. I'm using the Shibby Tomato Firmware 1.28.0000 MIPSR2-108 K26 USB AIO-64K.

    When i only enable the 5GHz with Channel Width at 40MHz, i can get 10MB/s with my laptop but when i also enable the 2.4GHz, i only get 3-4MB/s with the same laptop.

    I would like to know if it's normal. I really need the 2.4GHz since that my wireless printer and the iPhone that i have won't connect on the 5Ghz.

    Is there a way to solve this problem?

    My ddwrt acting as additional AP, connected to main tomato router FW, has no issue. If I swtich 5Ghz, I can see immediate change in link speed using window task manager.
