    Wireless Bridge mode -- better performance with DD-WRT than Tomato!?!??

    hi all,

    i have used dd-wrt for years but have just recently switched to tomato because of better stability (from what i've read). well, here's the deal.... i use a wireless bridge to connect to my main network router and with dd-wrt installed on the exact same router in wireless bridge mode, i would get about 1.3 MB/s download speeds without any packet loss. well, i just put on the latest version of tomato (not beta) and am using wireless bridge mode and am only getting around 300 KB/sec also with no packet loss, but about 1/4 the download speed. nothing has changed, they were both sitting in the exact same spot.

    is there a magic setting that i don't know about that i don't know about like turning off firewall or something????? i would really like to stick with tomato, but with 1/4 of the performance, i'll have to switch back to DD.

    any ideas??

    use the ND version it has a newer wireless driver it should work faster

    use it on the WRT54GL or WHR-G54S or both??????

    you can use it on whatever it simply has a Newer Driver
    that's why it's called ND version...

    but on the downloads page it says: » Use this for WHR-G125, WL520GU.

    i don't use either of these.....

    Try it it should work

    any stability issues involved? i would rather it be a little slower instead of packet loss or random disconnects :\

    depends on hardware revisions, I usually go for the newer builds the old build have some issues..

    newer builds of the routers? that could get interesting :O

    all my WRT54GL work flawlessly with ND version it seems snappier to me

    used it on any buffalo's? WHR-G54S or WHR-HP-G54 ?????

    no I don't think I did, but as I said earlier it should work and usually it works better
    some hardware revision (of the wireless chip) has some issues with random resets or such if you experience such errors then simply reflash the regular version.

    do ND and the older version firwares talk to each other trouble free or should they all be on 1 or the other in a WDS system?
     
  14. roadkill

    roadkill Super Moderator Staff Member Member

    yes you don't have to reset nvram it's only a driver switch they are otherwise the same
    and I think you can mix WDS of the two types without problems

    gotcha, thanks. i'll give it a whirl!

    Here is an screenshot of the Overview page from my Buffalo WHR-HP-G54 30 feet from my main router ASUS WL-500gP V2. Twenty Seven days up and running since last config change. I use WDS over bridge which I personally find to be more stable. I have a neighbor accessing the net wirelessly from the buffalo with a desktop and laptop. The Buffalo has not failed yet in performance.

    is there any risk of brickin the router by puttin ND on it?

    mastec-

    are you using ND ?

    Find out whar corerev you have. If you're at 7 or over, ND should work fine. Lower than 7 and you may have no performance gains at all. Lower than 4 and you might brick your router.
    To find out your corerev, type "nvram get wl0_corerev" in router console.

    prepare for a dumb question:

    where do i enter this in the tomato interface?

    Login through telnet to your router...

    i used putty. checked all 5 of my units and they are all rev 9.

    so ND, here i come!

    just change the filename of the ND download to .bin and let 'er rip?? this is going on WRT54GL and WHR-G54S units.

    I am using ND on both routers​
     
  26. though

    though Network Guru Member

    ok i put ND on the routers and i am currently getting 100KB/sec. with dd-wrt i would get 1MB/sec :(
     
  27. though

    though Network Guru Member

    and im getting some heavy packet loss (around 15%)

    like i mentioned before, all my units are rev9

    Now that's plain weird. Are you sure you're using the SAME settings as when using DD-WRT?

    You must have some thing wrong in the configuration. Did you do a reset to factory defaults after you upgraded?
     
  30. though

    though Network Guru Member

    did i do a 'clear nvram' ? nope, i have to do this remotely (they are in a different state in a wds configuration). guy in page 1 said it's just a simple driver update and that i don't need to reset it. i rebooted the units and nothing changed, but i did have someone power them off and back on and it seems to be much better.....

    would a 'clear nvram' be highly recommended after going from the 1.25 standard to 1.25ND ?

    If you didn't erase NVRAM after flashing from DD-WRT to Tomato this would almost certainly give you multiple headaches. Apologies if you've already done it though. Also, just to be on the safe side, try the NVRAM erase anyway. Because Tomato is usually fast. In fact Victek's 8515.2 release was clocking some of the fastest speeds of any normal G router.

    i think you misread. i did clear NVRAM after flashing from dd-wrt to regular tomato. speeds were bad after this so people said try ND which i have but didn't clear NVRAM after going to ND.

    This is correct, you don't need to clear NVRAM if going from Old driver tomato to ND tomato, as long as the tomato version is the same (i.e 1.25 to 1.25ND) However if going from any other firmware brand to tomato, you should definitely erase NVRAM.

    it's simply a driver change I don't think a clear nvram is needed
    since when the driver is initialized nvram values for all wl0* (wireless settings) are overwritten.

    ok. im still baffled as to why the throughput has decreased :(

    oh well...... let's get tomato support on the RT-N16 and i'll upgrade all my stuff :)
