I found different opinions about E3000 HW info, for example - http://en.wikipedia.org/wiki/Linksys_routers#E3000Quote:

I simply suspect that E3000 has much better stock firmware...
Can it happen that they have a newer (better) ethernet driver? It would be so good to get rid of the crapy TCP performance...Quote:

Btw I've found some interesting AHB description (some other chip vendors use it+separate ethernet for WAN and LAN no VLAN tagging thus sharing bandwidth).
MIPS74kc may have ~30% advantage in CPU architecture compared to MIPS24Kc and higher clock but the SoC chip may not be that shiny as Broadcom states (or would like to see).
And Broadcom's attitude towards open source developers simply shocks me after all of this.
All of my respect goes to lly, theMIROn and other developers who have done such an excellent job despite the difficult situation.
Update: One more question, would TCP/UDP checksum calculation offload possible with these chips (or is it already used), so that MIPS CPU is not loaded with this?
you can request them to put it up it seems: http://linksys.custhelp.com/cgi-bin/...er/gpl_ask.phpQuote:

Even that way, how it's possible the same hardware (and even worst, case of WRT320N) with so much diferences of performance? It's a HUGE diffence, something is not right...Quote:

Broadcom does not supply any kind of updated drivers?
Thank you all for replying :D

Routing performance for the E3000 using our standard test method is summarized in Table 1, along with the 610N's (V1) test results for comparison. Since the CPU is the same Broadcom BCM4705 for both routers :confused:, the E3000's higher performance can only be attributed to improved routing firmware. I don't have a 610N V2 to test. But I'd imagine that its current firmware would provide similar performance.
Can this updated SDK mean some better C compiler? I know that MIPS 74Kc can re-order instructions but it checks only up to 8 instructions so quite much is left for the compiler.Quote:

Update: This dual long 74Kc pipeline may require quite different code to run efficiently...
right now we use the same (modified & updated) toolchain as asus used in their WL-500 models.Quote:

What they used for compiling the pre-compiled drivers is still a mystery :p
SDK's also include drivers and api depending on the type of product it's for.

Actually it is completly the same. I use firmware from Asus and I use ipkg repository for WL500G. I was also using toolchain for WL500G to compile and run software for my RT-N16.Quote:

Has anyone tried to compile GPL sources from Asus for RT-N16? They fail to compile with bizzare warnings and there is no FAQ :)
I requested the GPL source for the linksys E3000 router...
who knows, they might put it up:D
It cannot be compiled "out of the box", you have to fix many warnings & minor errors... There is no FAQ and it cannot be written, because errors are sporadic and it is impossible to teach use of compiler & tools in one small document.Quote:

Dear Customer,
I am currently having engineering look into this GPL for you. I will let you know when I hear back from them.
Thank You,
GPL Manager
I see, I see. But the problem is not in warnings. The problem is in errors. If I do make from src it fails with errors. However, if I enter router folder and do make N16 it goes ok for several minutes untill again breaks with error ..Quote:

lly said "minor erros", so I guess he's talking about those.Quote:

the old oleg fw was good, but in that form it could never grow as mutch as the new oleg fw.
Obviously I'm not saying oleg did a bad job, thanks to him we have all this in the end:D
Well, that's how it is called in russian.Quote:

I have applied "thermal adhesive tape" in all, the temperature is very low, 29~30º with router closed :D
Dry ice :D L.O.L
Anyone tried 3G Connection on the current firmware? Does it work ok? Firewall / Forwarding issues?
I've tried Koppel & Mango FW and i simple CAN'T redirect / open / forward ports (firewall not working) Anyone?
Thanks in advance.
3G modems support now in development (in the first place for wl500-branch). Current version contains two branches of dial scripts - Koppel`s and our universal dial script.Quote:

Try to use latest version at ftp://core.dumped.ru/rt-n/ with universal dial script.
Hi,
I have had a wl-500gp for a couple of years now with Oleg's firmware and has been happy with it. Now I have got hold of a Asus RT-N16 and I assume that I can expect some performance improvement compared to wl-500gp.
Am I correct?
I have mainly used it with transmission and as file-server on my LAN.
What is the recommended firmware?
I see that RT-N16 have 128 MB ram. Do you still recommend to setup a swapdrive?
Yep, significantly faster.
I have found the latest rt-n alpha firmwares have been mostly stable ftp://core.dumped.ru/rt-n/ (you can see whats changed here) and I have been updating mine every couple weeks. But always back up your settings before firmware upgrade, regardless.
Tutorial on N16 firmware and optware config ... http://wl500g.info/showthread.php?t=23684
Always try use swap-space, and best to keep it larger than physical memory. My N16's been up for 3 days and consumed no swap yet.
My N16 is slowly increasing the usage of its memory. I have used wengis tutorial.Quote:

Transmission is running with two active torrents, but no download/upload
This is a problem when you want to spin down the harddrive.
Should I just do a swapoff?
it's just cache and bufferingQuote:

yet it's unusual that it increases that much.
When you do some work at samba after a reboot you can see the usage increasing btw.
You were right. I killed Samba and the usage of memory stayed on 33 mb.Quote:

Good idea, but transfers might be a bit slower:)Quote:

Hi guys! It's been almost a year since my last visit but you know... I had a perfect asus WL-500GP v2 with Oleg's fw and I was happy all the time :) Yesterday I've bought an RT-N16 and the problems, unfortunately, begun.
As you all know the Asus FW sucks, so I tried Olegs and ddWRT to test if I get better performance, since I have 1 media centers (cat5), 5 laptops (wifi), 3 smartphones (wifi) and a homeserver (cat55), all connected to de RT-N16.
Strangely I got no wifi neither with oleg's neither with ddwrt unless I put them exclusively on channel 1. I don't get it, how is this happening? Can you help me?
I use open system security with mac address access restriction.
Thank you very much and sorry for my English.
Hi, was the WIFI working with original ASUS fw?Quote:

Currently the 2.6 builds available (dd-wrt, Tomato, stock) use kernel versions around 2.6.22-24 and the proprietary Broadcom driver. OpenWrt trunk currently uses 2.6.3x kernels."
As you can dig from OpenWRT svn, they receive contribution with partial sources of broadcom driver 5.10.56.27 for MIPS.
It use in our firmware requires deep tests, since we hasn't any knowledge about binary part of it. After this, we should try to port Broadcom SDK to newer kernel. It is large task too...
Thanks for replying! :)Quote:

In that case you can try those:Quote:

2. Check if you wifi is working after loading defaults, before you costumize any setting.
3. Try to connect to the router in other computer, and see if the same problem is happening.
Can anyone tell-me if jdownloader (http://jdownloader.org/download/index) work in this router ?
No java on the router...Quote:

Hello
My old wl500gp(oleg firmware) I can use usb sound stick with build in driver(soundcore.o and audio.o) and play music with madplay.
Now I turn to rt-n16(oleg firmware), but I can't find audio driver. Can I use usb sound stick to play sound on rt-n16?
Thanks,
Thanks,Quote:

Do you have this noise on your pc as well?Quote:

Great to hear. I've upgraded to the latest version, loaded modules but need to test it out with some player when at home. Thanks.
Is there anyone to help me understand how to make bluetooth work (i.e. how to add/build necessary modules e.g. bluez.ko)?Quote:

Very thanks wpte, I loaded latest rt-n16 firmware and modules from your site. :DQuote:

I played sound on rt-n16 with same environment(different only driver modules).
I tryed low volume, but noise still come out.
