    1. Is the RT-N12 B1 better than RT-N12 in terms of hardware specs?
    2. Does RT-N12 B1 work well with tomato? What about mods and 2.6 kernel support?
    3. I've tested the N16 and it's a very fast router. Well, I don't need the downloading feature, usb feature.. will the N12 B1 be fast enough? I am looking for a router to replace my WRT54G-v2.2, which already has all my requirements.. except that it's not that fast.

    Any reason to suggest those routers over asus? I had the impression Asus routers are the most superior currently.

    1. Key differences of the RT-N12 B1 over RT-N12 (v1).
    8MB flash (vs 4MB) which allows for larger code and possibly additional functionality
    Higher gain 5dbi antennas

    2. Toastman and Shibby have special builds for RT-N12 B1. Still "experimental" though.

    3. RT-N16 offers
    60% faster CPU clock so can handle more complex rules/configs,
    Larger flash and RAM for more functionality
    Wired clients get faster throughput using Gigabit ethernet
    USB support for shared printers, storage, NAS functionality
    This gives you a more future-proof router, IMHO.

    I had the RT-N12 v1 and have had issues with long-term stability - I would lose wireless connectivity after extended periods of operation. I recently switched to the RT-N12 B1 but have had issues with the Bandwidth Limiter function, so far. I am hoping for an update from Shibby to fix this soon.

    The main advantage of Cisco/Linksys routers are they provide dual band radios so if you have frequency or range issues, this may be a key differentiator. They are limited to internal antennas, though - I like the option for high-gain antennas to increase range. They usually cost more - so it really depends on how future-proof you want to be.

    They have dual band radios, but 5Ghz offers shorter range than 2.4Ghz. The performance is higher on 5Ghz, but in my house you've got to be right on top of a 5Ghz AP to get it working.

    The primary advantage of the Ciscos is internal antennas, which is only an advantage if a functional arrangement of external antennas bothers your aesthetics. If you can leave them in the correct orientation (and are willing to drop a few dollars on higher-gain replacement antennas if the stock units don't work well in your environment) then external antennas are superior.

    So I take that the RT-N16 has no issues whatsoever generally, especially in terms of stability. For common setups, the RT-N12 B1 should suffix then...

    I do wonder if the 60% faster CPU really makes any difference at all. Good if someone here has first hand experience with both to comment on 'speed'.

    They simply are more stable. Remember it is still Cisco behind them.

    I stress test routers with a large number of torrents from private trackers and the only ones that never lock are the E3000 and the E4200. NETGEAR worse of all.

    I will get an RT-N16 and an N66U and test them again with the latest Tomato builds.

    The RT-N12 has some questions about reliability, but I've had an original model setup (though, admittedly, in a public access style completely-locked-down configuration) for nearly a year now without a single hiccup or chirp.

    I swear it's running one of Teddy's builds too, but I haven't gone down there to verify that.

    At home I ran a WRT-54GL for years without problems, and for a couple months now have had an RT-N16 running in it's place, and both got/get absolutely decimated in terms of torrents. I'm not sure why I'm so lucky, but my day job is in IT, so I routinely see the "hey you walked in the door and suddenly it started behaving" phenomenon.

    If it did start failing though, I'd start out by taking regular metrics of the router to get a snapshots of what the statistics are in terms of load, RAM utilization, interface bandwidth, etc. It's just Linux, you setup a 2nd system to open a connection to it, pull statistics out of it, shove it into a database, then close the connection. Then run that script every 10 or 15 seconds. After a while you should get a very interesting picture of what's gone wrong in the minutes leading up to the crash.

    Model CPU Clock RAM ROM
    WRT54GL BCM5352 @ 200MHz 16MB 4MB
    RT-N12B BCM5357 @ 300MHz 32MB 8MB
    RT-N16 BCM4718 @ 480MHz 128MB 32MB

    You just need to figure out how much more headroom you need. RT-N12B1 has 50% faster raw clock speed. The RT-N16 goes 140% faster.

    This chart shows that the RT-N16 can give almost 3x the throughput of the WRT-54GL.

    DO share that info when you test them.

    Is it right to say BCM5357 is newer/better than BCM4718.. in the sense of following numbers?

    The N16 has tried and tested reliability and the other one has had reports of sketchy reliability.

    I'd pony up the extra dough if I were you and just buy the N16. Best router I've ever owned. It's got the reliability of my WRT54GL but with the extra hardware benefits. It will last me years.

    I have a question though. Do you need N wireless for your home setup? Do you have an internet connection over 50 MB in bandwidth? Do you stream HD video from your NAS to a set-top box on your TV? If not, you don't really need N wireless. You won't see a difference between your current router and the N16 unless you specifically need the radio to transmit at N speeds.

    Many people buy an N router thinking it will magically make their DSL internet faster, but it doesn't. If you just want longer range to cover a large home, just get replacement antennae.
