No AC on Tenda W1800R runing Tomato by Shibby (116-EN AIO)?

    I have successfully flashed my W1800R with the latest version of Shibby's Tomato.

    When setting up 5ghz network, available network modes are Auto/A/N. There's no AC. When connecting from a laptop using with Intel AC 7260 NIC I can't get above 54Mbps under any circumstance. There are no other 5ghz networks around.

    Should I be seeing an AC option in the firmware? I've looked through most of the settings, and can't figure out what's wrong.

    Any help appreciated.

    leave mode as Auto and set channel width to 80MHz.

    that did it, thanks.

    why no ac in the network mode dropdown?

    the tenda firmware is much appreciated.

    tomato + w1800r = amazing value!

    I recently got this router and still running the original Tenda 2.0 firmware. Everything is working fine so I'm not sure if I should risk updating to Tomato. Have you seen any improvement in speed or range? Especially at 5Ghz 802.11n 40Mhz.

    I would feel safer trying Tomato if there was a method to go back to Tenda firmware.

    well, if you're happy with what you have and all's well, that's a strong argument to keep on keepin' on.

    dunno about performance diffs. i assumed the tenda firmware to be crap. the only thing i used it for was to install shibby's tomato fw (and the availability of shibby's tomato fw is the only reason i picked up a w1800r.)

    firmware does nothing magical, so the physics of radio waves propagating through my house are the same with either fw. the only real difference is the radio drivers, and i assume they're very similar, if not identical.

    what i can say is that the w1800r outranges my ac-66u at 2.4ghz. on both routers, the 2.4ghz network significantly outranges the 5ghz one. and that's totally expected, given the characteristics of the two bands.

    tenda fw seems available here: if you want to revert.

    Thanks for the feedback. While I would love some of the additional Tomato features, my main concern is range and speed for my older clients limited to single stream (150 Mbps max) 5Ghz 802.11n. I'm currently averaging ~5.5 MBytes/sec copying files to those clients from my NAS. I would hate to see that degrade and have no way to go back.

    Having the Tenda firmware file available is no guarantee that it can be re-installed after going Tomato. Doesn't the ac66u require using an Asus recovery utility to go back to stock? I suspect that the Tenda would also require some special method - maybe tftp server?

    Let's say your router had some hardware failure within the warranty period. Wouldn't you also need to flash back to stock before sending it in for service?

    (for the uninitiated reading: MBps is megabytes per second. Mbps is megabits per second. 1MBps = 8Mbps.)

    5.5MBps is 44Mbps. i write off half of a connection's reported speed, so for 150Mbps that gives you 75Mbps. then there's the wireless encryption overhead, rule of thumb say reduces available throughput by ¼-⅓. by that estimate, you have 50-56Mbps of usable throughput, which is fairly close to 44Mbps.

    do you have security enabled? if you disable it do you see any increase in network speed? if you answer yes to both of those, that's relatively definitive that you're maxing out your wireless throughput.

    i might not be surprised if you can wring 50% more performance from your described setup. to get to a 3x improvement (~15MBps) you're probably going to need relatively heroic infrastructure changes. and even then you're moving 1GB in 1 minute vs 3 minutes.

    this is not to throw aspersions on your technical skill, just the numbers are what they are, to an order of magnitude. :)

    as to fw reversion and warranty... valid points. see previous note about keep on keepin' on.

    I loaded Shibby's 116EN firmware, but I noticed the 5Ghz LED light won't turn off even if I disabled the wireless interface.
    This happened on Victek's 1.2x firmware as well.

    Is there some special process to flash the tomato firmware onto W1800R?

    Can I flash via Web GUI as if I am updating to another Tenda firmware like explained in this video?

    Do I need to do the 30-30-30 hard reset?

    Or is there a site with instruction on how to flash Tomato firmware?

    And is this the latest firmware for Tenda W1800R?

    I just did it through the Tenda web interface.
    Your link is correct, just pick the Tenda folder. I use the AIO and everything seems to be working for me except the 5Ghz LED.
    After the flash, I went to administration-->configuration-->erase all data in NVRAM.

    Hi, anyone know if we can increase the 16MB memory to 32MB chip on these W1800R and W1801R routers?
    I've seen hacks for other routers and devices where they were successful. I am comtemplating such a project for my new W1801R. Anyone knowledgable on this?

    Any ideas about optimal power settings, both 2.4 and 5Ghz?
    Also, what would stock firmware 100% power setting be on Tomato FW?

    And, if anyone knows, are the external antennas for 2.4 or 5Ghz band?
