MikroTik

mp3turbo2

good to know! I don't expect such boost on full-powered beasts, but seems like the code is getting optimized what is excellent sign.

Thanks for sharing info!

mp3turbo2

speculation : could this higher performance be due to PROPERLY WORKING hardware compression of atheros cards? We all know that bandwidth test uses compressible data, at least to some extent.

somebody from mikrotik wants to shred some light here?

mp3turbo2

hi stephen,

what about fast processors like your mobile Pentium platform ? These results are far more interesting than ~20Mbps :)

thnx!

mp3turbo2

thanks martini, how is it possible that there is just so small portion of people here that can provide real answers?? I will perform extensive testing next Monday and Tuesday, I guess around 6 hours will be devoted to hardware compression tests (2.9.1, 2.9.2 versions) and nstreme2.

mp3turbo2

which CPU? Routerboard or p4/3GHz ?

mp3turbo2

gyus, questions are:

> Significantly improved Nstreme performance

how much is nstreme improved compared to v2.8.28 ? What about nstreme2 and is anyone successfully running 2.9.1 with atheros HARDWARE COMPRESSION ?

thnx, mp3turbo.

there were some quirks and rough edges from the very early 8139 batch, but recent revisions, like C and D (you shouldn't be able to buy anything but 8139D for more than two years) and 8100 recent revisions should be behaving correctly.

problem is that MS round-robins servers (DNS names and their respective IP addresses, even there is load balancing - more IP addresses under one DNS name).

as far as I know, 8100 are from 8139 family - and they work with the same binary drivers under Windows2000. So they should work with MT, as 8139 is supported.

I would guess that this fluctuation is more card-dependent than software dependent. We have replaced some noname taiwan cards with brand-name ones and the link has trippled in throughput and totally stabilized pings (1.5ms to 2.5ms) as the radios do not switch speeds every second. Of course, there c...

hello all,

may we know what was fixed here? And probably what is / should be the performance difference ?

thanks!

mp3turbo2

yes, it was :) right now, we have:

signal-strength: -67
tx-signal-strength: -60
tx-ccq: 75
rx-ccq: 75

why is it so different, still ?

mp3turbo2

hello, didn't try legacy wireless module. Nstreme reports -80dB signal strength, -61dB tx-signal-strength, but is capable of transferring data corresponding to -61dB signal :) probably this is just cosmetic or so. Upgraded from 2.8.13, where signal strengths were shown as -62/-61, so almost similar ...

mp3turbo2

yeah, simple BitchX would do it. International calls are pretty expensive today.

mp3turbo2

I wouldn't say it this way - "it doesn't help at all " is not the diplomatic way :) There are many situations where current attitude is right and there are situations, like your replacement, where your system would be more helpful. Probably there could be some command to take settings from...

hi grifter, no problem, you're welcome. I just thought the answer was clear from the first post as Nstreme is own and unique child of this company - nothing in 11a, 11b or 11g mode will associate to it and I think that regular devices will NOT even scan SSID from Nstreme APs. They could only see som...

there is ONLY one thing able to associate to nstreme AP on this planet : microtik nstreme client. once again : the only thing able to use nstreme is mikrotik server and mikrotik client.

mp3turbo2

hi,

answer is the same as for question : will karlnet client work with standard 802.11b AP? Nstreme is modified wireless protocol, it just uses the same frequency (physical layer).

quess what the answer is...

bye, mp3turbo.

mp3turbo2

I can confirm, I was not able to connect on the lowest possible frequency. Everything else works, so there could be probably some typo in source code or so.

mp3turbo2

I observed this, too. With standard 20MHz channel spacing and standard driver, everything works as expected. Switching to Nstreme or Turbo... OMG.

yeah, I observed very similar behaviour. So far, nstreme with g-turbo is not the best combination. BTW, you have to have excellent signal for g-turbo to function properly with full transfer, don't count on -78dB !! for mikrotik company : this is our official statement : so far, we found the fastest ...

my experience tells me this is safe to do as we rebooted / switched off routers hundreds times. We use classic ATX computers with PCI wireless cards and EIDE harddisks.

best way to do this is... OSPF.

There are no rules, no pptp, no ciphering, no NAT - simply nothing, this is ju...

I'd guess mikrotik only.

John, another observation : when I choose dynamic-size on AP, client shows exact-size -> probably bug.

All other modes are working as expected (ie. fast-frames shows fast-frames, exact shows exact).

btw, original 2.8.13 wireless file has date aug/11, time 13:35 ; after trying to install n-streme v12, this file is changed to aug/11, time 15:09 - does it mean that despite of "package installation script failed" error this package is installed ? I'm going to try it, but I don't have wire...

mp3turbo2

yeah, I have problems installing v12 - installation fails on three machines stating always the same : something like "package installation script failed - couldn't install"...

Anyone else experiencing this?

what are the differences between v11 and v12 ? Probably managing some change_log for n-streme would be helpful :)

none. We were facing tough decision as the traffic changes all the time, as does number of connected clients etc, etc.

Final conclusion : it did more hurt than help. We were not able to optimize it, but this is not problem, limitation etc of this system - this is nature of such a setting.
