This is very odd (note the size of the mtd partitions):

Code:

root@Asus:/proc# cat /proc/partitions
major minor #blocks name

31 0 256 mtdblock0
31 1 32384 mtdblock1
31 2 5733 mtdblock2
31 3 128 mtdblock3
31 4 25344 mtdblock4
8 0 7827456 sda
8 1 7825423 sda1

Code:

root@Asus:/proc# cat /proc/mtd
dev: size erasesize name
mtd0: 00040000 00020000 "cfe"
mtd1: 01fa0000 00020000 "linux"
mtd2: 00599400 00020000 "rootfs"
mtd3: 00020000 00020000 "nvram"
mtd4: 018c0000 00020000 "ddwrt"

root@Asus:/proc#

The cfe is the correct size, but mtd block 1 is only 32MB? Not 128MB?

sda and sda1 is my flashdrive which I still cannot mount, but yet the size is correct...

Please think before you speak (post). Flash is 32M; ram is 128M... Clear?

Just replaced my in service WL-500gPv2 with my new RT-N16.

Most impressed. The speed that the UI responds is very quick.

I've recreated my port forwards, they all work.

Wireless is fine, although I only have .g clients. Range seems as good, if not better, than the WL-500gPv2.

It took a long time to clean the jffs partition, which makes sense given that it is 24Mb. (I'm not using USB on this router)

Nothing I'm doing is actually taxing the router, nor was it taxing the WL-500gPv2.

I have not yet noticed any high cpu usage.

All I have remaining to test is OpenVPN server, which is the primary reason I purchased this router. Will report back on those results.

Dear Eko, thank you for firmware. I just wish to report an issue - after flashing my router I've got problems with WiFi - long pings to router, reconnections and so on. I thought there are problems with channels, changed them without success. The problem was fixed lowering TX power from default 71 to 20. Now it works like a charm.

Other issue from me:
root@DD-WRT:~# wl status
wl:status ->wl driver adapter not found

2nd issue I think Eko already answered above

"With NEWD-2 driver you must always include interface in wl command: like: wl -i eth1 status"

Thanks for the info about the power setting, I'm making notes, waiting for mine to ship....

I'm sorry, missed it, yes, "wl -i eth1 status" works fine. Thank you!

I've also been having wireless dropouts. Have changed wireless TX power to 20mW as per the post above and will monitor. _________________ D-Link DIR-300 Asus RT-N16 Asus WL-500gPv2 Linksys WRT54GL 1.1 Way too much time.

changing tx power to 20mW seems to help here. with 71mW i was experiencing similar problems like sysdemonmsk.

So this has been running really well considering its the first build for this router and its the new 2.6. UPnP though definitely does seem to cause high CPU usage with it eventually going to 100% CPU usage. It seems a bit delayed after actually using a UPnP enabled program (utorrent in this case) but it eventually kicks the CPU up. Disabling and rebooting fixed the problem.

Haven't tested wireless yet.. will post soon about that.. although I only have a g card.

Edit: Wireless didn't work until I dropped my TX power to 30.

Also, looks as tho the CPU usage is a problem with all 2.6 builds (like in the WRT320n thread)

I don't know what you are on about, your cpu is 97.2% idle there.

Look at the load average, and my screenshots..

Can you describe what Load Average measures?
What are the limits, and what does it mean if you are exceeding them?

I think you better stick to the CPU field in top, you can compare that with individual processes %cpu to see if there is something wrong.

There is clearly a problem LOM..Not only does the CPU graph indicate high CPU usages, but the web interface itself actually slows down quite a bit. Also, if you read further back you will notice that the firewall blocks UPnP responses, allows IP Multicast thru the firewall (not good), and will randomly delete the UPnP port forwards (i.e Skype, Windows update, certain games etc.)

I wouldn't pay too much attention to that graph either, your 79% is the average over the last 15 minutes and you have to know what the figures means.

Take a look instead in your top output and tell me which process you think is loading the cpu heavily.
