Hello guys,

I have a Linksys E3000 which I would really like to run on DD-WRT.

Unfortunately it seems that it´s not performing well with it. I have a 128MBit/s cable modem behind it. If I use the stock firmware it is able to push the link to it´s limit. If I use DD-WRT it only achieves rates between 30-50MBit/s.

I tried several different DD-WRT versions (the last one was dd-wrt.v24-14929_NEWD-2_K2.6_big-e2k-e3k), the result is always the same: Bad throughput. As soon as I revert back to stock the performance is back....

I was wondering if anyone has similar experiences with the E300 and/or could give me a tip if there is a chance to boost the throughput.

(I´d really like to use netflow and snmp.)


Best regards,
Fusion

For such a fast connection you need this build:

Hello Kong,

thanks for the tip! I´ll try your build in the evening.

A shame it has no rflow, this is one of the main reasons for me to use a non-stock firmware.

Any chance you might include it in the future?

Hi fusion,

yikes, I have to add it to the E3000 build again, as it is included in my default builds.

I'll rebuild them right away and then upload them.

[<Kong>]

Ok, just uploaded the updated e3000/e4200 build which inludes rflow.

Hello Kong,

many many thanks!

I´m a little bit uncertain what to download now.


Is it http://www.desipro.de/ddwrt/dd-wrt-e3-usb-ftp-samba3-vpn-O2-v24-K26-broadcom.bin?

I downloaded this yesterday and neither filename nor size have changed so I´m a bit suspicious if this is the right file.

[<Kong>]

I always keep filenames so links that point to my build always point to the latest version. Size does not always change even if it is a bit bigger or smaller this comes from the packing that is done by the firmware build tools.

[fusion]

Ok, just wanted to be sure .

Will try it out and give some benchmark results.

Many thanks in advance!!!

Hello Kong,

I updated a few minutes ago. Throughput speed is stable at 128-138 MBit/s. Great! So far so good! Many many thanks for that!

[fusion]

Hmmm, I´m afraid something is still weird. After ~1h of uptime the throughput speed drop to ~ 50-60 MBit/s. Rebooting doesn´t help. A factory reset solves the issue instantly. Back to 120-140MBit/s with the same router settings as before.

Any ideas?

You could try TomatoUSB and its various branches worked on by different developers.

[<Kong>]

You said you are using rflow.
Did you check once the throughput drops, if rflow or some other process is eating up cpu?

If only a reset helps, then it must have to do with things in nvram , maybe once there are some values stored some process is consuming more cpu power.

[fusion]

I did some further testing.

Meanwhile the throughput is stable @ highspeed (120MBit/s) but only with a single connection (like one big http download). As soon as I´m using multiple connections (20-30) the throughput rate drops to ~ 30 MBit/s.

Any ideas?

I'm a happy Kong e3000 user. I get great speed and extra features. Just running it a day now, so I will tell later if it's stable.
