can't get connected at more than 54Mbps on 2.4 or 5Ghz?

    I've got tomato installed on my Linksys E3000 and although I am able to get connected via my laptop or phone on the 5Ghz wireless, I can't get over 54Mbps (with a real throughput of around 15Mbps) on either 5Ghz or 2.4Ghz, which is a little frustrating. I've tried the 40Mhz channels and upper and lower sideband, but nothing seems to work. is there some other setting I'm missing?

    is there a better firmware for me to be running on it? the current firmware on it is: v1.28.9054 MIPSR2-beta E3000 USB vpn3.6

    Try just using aes encryption

    Were you able to connect at a higher speed with stock firmware? Is WMM enabled? Did you clear NVRAM after flashing Tomato?

    disable Afterburner... it happened to me when I was on a quest for maximum speed!
    Later edit: just noticed you use TKIP+AES change that to just AES.

    A screenshot of your advanced wireless settings may be helpful in addition to the above.

    When it comes to wireless n

    AES and WPA2 encryption. Those are the only that will work with wireless n settings.

    When I have that working, My laptop gets about 84mbs connection from my laptop to a wired desktop connection when I am within 10 feet of the router. At about 40 feet through a couple of walls, it would drop to about 26mbps.

    And I read that 40mhz channel can be a bit prohibitive if you are in a crowded area so it would be better to just switch to a 20mhz channel

    Hi, sorry it's been a while, i didn't realise I'd gotten any replies.

    I managed to get up to 150Mbps by removing TKIP and turning off the afterburner (that thing that's supposed to make it faster!) so i'm happy with that, thanks.

    Just in case there's anything I could be doing to get a bit more speed, I've added my advanced wifi settings if anyone could have a look and see any way to improve things?

    thanks again for the help, i'm a happy camper! :D

    Switch to short preamble for slightly better throughput. Consider disabling Bluetooth coexistence and interference mitigation, or at least testing with those features enabled and disabled. Same goes for Frame Burst. If there is absolutely no 802.11a traffic around, and all 5GHz devices are n, then you can try the green field preamble on 5GHz. None of these will increase the "connection rate," but they may get you a bit more throughput for wireless traffic.

    Changing wireless Country to Singapore and setting transmission power to 0 may also be helpful for signal stability.

    yep, much better thanks. :)

    here's the before and after.

    Never got more than 48-54Mbps connection speed until now, but had it up to 117Mbps from the next room with the tweaks.

    Every time I see the ping I keep thinking i really should get gaming online again. :D
