Shibby 115: max 5GHz speed only 130 Mbit

    Hi there,

    My 5GHz wifi on my RT-N66U (Shibby 115, AC branch) only connects to my MacBook Air with a max connection speed of 130 MBit, no matter how close I get to the router.

    I have not touched the advanced settings. I wonder if this is due to the AC build I am using.

    Anybody else having this issue?

    well to have wireless AC you'd need an RT-AC66U

    130 mbit isn't unusual for 5ghz N, tthough you should be able to get more. have you tried uploading (sending file from a macbook air to a wired destination)

    Shibby has builds for the N66U in both the RT-N branch and AC branch on his website.

    What channel width did you specify in the Basic settings and what is being reported by the router for channel width? Anything in your Macbook hardware or settings restricting to 20MHz? Did it work at 300 or 450 with other firmware?

    Yes, it did give me 300 before. I think it was anywhere around 108/109/110, when it worked, and after that, it went down to 130 ever since.

    I am set to 40 MHz, but the status page shows, that it is only on 20.

    Just this weekend I reinstalled 115 AC anew (without restoring the settings and starting from scratch again), but this didn't help.

    This actually happens to several macs in my network, so I don't think it's a config change on the machines. I wouldn't even know how to do this in the first place :)

    Update: even after updating to v116 the 130 MBit limit is still there.
    Both wifi networks show 20 MHz, although I have set them both to 40 MHz/Upper.

    Really odd.

    I tried the AC build for my N66U but I had problems with radios not starting and connectivity problems. I would suggest to go to the RT build for N66U at least until it is supported by Shibby.

    clean nvram and try again?

    Yes, as mentioned in my initial post: I did a clean install with deep nvram flash and I was still on 20 only.

    I use the same firmware (1.28.0000 MIPSR2-115 K26 USB AIO-64K) and HP-(Business-)Notebooks connect to RT-N66U with 450Mb/s (eff. up to 28MB/s)

    The fix for this was to manually set the channel, both were set to auto before.

    Now I am on 40 MHz.

    how are you determing the connection speed? looking what the router indicated? cause i dont see u posting and tests or anything. i dont know why people cant use common sense about this. the indicated speed means nothing. right now i have a macbook pro synced at 450, yet the router shows 108, when i do speed tests on this. it always hits 200+mbps close to the router. i have been running a test on an iphone 5 before AS THE TEST IS RUNNING IM GETTING 90mbit/sec, and the router showed 42/150 or something (basically claiming the receive rate on my iphone was 42mbit when i was watching it do double that. indicated speed means nothing and should probably just be removed. now could u plz just post results from tests rather then complaining about your indicated link speed which is 100% irrelevant

    First off, I wasn't complaining, rather reporting and asking if anybody has seen this.

    Apologies, if I have insulted your common sense sensors, but did it ever occur to you, that there might be forum users who don't speak English as their mother language and thus use less perfect descriptions for their problems?

    Second, if you would have taken the time to write your post for reading through the thread instead, you would have seen, that my reduced sync problem started somewhere at FW 109, before I was fine.

    I actually found the answer in another thread, where it was noted that the auto channel setting locks the router to 20 MHz, no matter what's set in the basic wifi network settings.

    My sync speed is back to 300, while it was "locked" to 130 before, as soon as I manually set the channel.
