5 GHz speed on RT-AC66U

    What is the maximum "rate" you guys see on an RT-AC66U with Tomato? Mine only goes to 173 Mbps. I ask, because I had an Apple Airport Extreme (latest version), and in the same location (a few feet from my laptop), I would consistently get 600 or 700 Mbps (confirmed by the Intel Proset Wireless utility in Windows). Is 173 Mbps the maximum Tomato allows? Not that it really matters, but for file transfer from my gigabit LAN, it's nice.

    i notice the speeds reported are lower but for me performance is equal to asus and merlin-wrt. i think if you actually did some testing its most likely to probably get better results then your airport extreme.

    Did you actually test this by performing a file transfer from a wireless computer to a wired computer? The connections speed as reported by a utility has been unreliable since dial-up.

    yes. full 1gbps link straight into a 2 stream 5GHz N client. no AC was tested. multiple 100MB tests were ran, i also did testing on iphone 5 via speedtest app. never got over 80 on the Asus FW. hit 81 on tomato. single stream N 40MHz

    I was able to push ~225mbit Wireless N 5Ghz uploads to a wired server on my e4200v1 FWIW , with tomato.

    225mbit with RT-AC66U and tomato? i didnt even think the router could pass 180 with tomato. are you sure your numbers are right that doesnt make sense.

    lol SMB is not really a lab test. its a real world enviroment test in someones house.

    also there are many AC routers that can top 400mbit throughput. lol if they couldnt cross 400mbit that wouldnt even be 1/3 of the 1300mbit link speed potential.

    There are several people in this forum pushing wireless data at that rate on a daily basis, myself included. It's well within 802.11n capabilities, particularly in 5GHz range where there is usually less WLAN and non-WLAN interference.

    i never said the wifi link couldnt hit those speeds. but the processor without HW acceleration on cant hit above 180mbit. tomato doesnt have HW acceleration as it is a closed source broadcom code, im sure the RT-AC66U can hit 220mbit on 5GHz N. but not with tomato.

    or would it be possible to have HW accleration on in tomato if QOS and ip traffic were disabled? well i still use the BW limiter anyway, but im like 99% sure tomato cant use HW acceleration.

    @Connor. HW acceleration has nothing to do with wireless speeds. Broadcoms HW acceleration only speeds up NAT. If you transfer from a wired PC to a Wireless PC HW acceeration does not kick in. If you look at other benchmarks for example at smallnetbuilder you will see, that oem has the same speeds as tomato if nat is not an issue. I have not seen any wireless benchmarks that shows more than 400Mbps in one direction if AP-Client test is done. If we are talking about bridging two routers, then you will see different speeds.

    My 225 mbps result was with a Linksys 4200v1, which is slower than the Asus router (480Mhz only). This was only achievable when uploading from a macbook pro with a recent Intel N 5Ghz chipset , download performance was less. The router's CPU was maxed out during this traffic.

    However, logic would dictate that a faster router like the Asus (especially since it has AC!) should be able to beat these numbers. I use tomato shibby.

    just to let you know. im pretty sure the above isnt a "lab test" but it is a very accurate real world test. i do agree with that. though i still think there is many AC clients that can do more then 400mbps, there are even routers on the charts at SMB that go over 400mbps at max. so i dont know what your talking about

    as for only getting over 400mbps router to router. u realize that the new MBP's and lots of laptops will soon have 3SS AC Cards Supporting the Same 1300mbps link rate as the routers. so no its not only routers. but it had been for a while yes.

    you are correct. thank you i didnt know this.
