I got a brand new laptop at work which is usually connected to the internet via ethernet cable with a bandwidth of 100 Mbps.
Lately the clean energy task stopped appearing on my list of tasks. I saw this in my message log: 12/1/2013 10:17:55 PM World Community Grid Message from server: The Clean Energy Project - Phase 2 requires 63.48 KB/sec download bandwidth. Your computer has been measured at 30.09 KB/sec. Since when has the "download" bandwdith been measured? And why is it seeing much less bandwidth than 100 Mbps or somewhere 10 Mbps when connected via wireless? How can this be resolved? |

Adding the following if this helps.

See all the other previous posts on this "New device, no CEP2". Latest tech reply translation: We are in a code freeze... not going to be fixed until the back-end has been upgraded to deal with variable sized tasks [for differently capable devices... small for Android, big for the 3930's]. Only way that might overcome the 'not getting' is to set the device profile to CEP2 unlimited or just wait it out... can take 48 hours when suddenly they start appearing out of nowhere.

Oh wait, the 63.4K BW limit. Has always been, the 'wrong BW' why many times explained too! Set CEP2 selector to allow at least 2 on a client in the custom section of the device profile. One of the sticky posts at top of of Clean Energy forum.

In addition, the 100 Mbps connection for your ethernet is NOT the same as your internet bandwidth. 100 Mbps is the maximum theoretical connection the ethernet port can handle. You can test your actual internet bandwidth through a site like speedtest. On the corporate side there are usually limits in place per port, to prevent one system taxing the network. Just an FYI.

Interestingly, when my computer from which tested is connected by ethernet cable [router is 100Mb on wire], it shows better numbers than when same on WIFI [300mb 802.11N only]. Maybe it introduces another layer of latency, like the overhead of transferring many small task files causes BOINC to 'measure' the connection to be much slower. Got 20Mb, but it shows 200Kb in the client_state at present. Opposed, when receiving an MCM task with that 32Mb txt file, the measurement shoots up to 2Mb near the end [courtesy of 'on the fly compression / decompression' whilst transmitting]. Suddenly, then those CEP2 will come if the setting is only 1 - default.

I have the same problem. And no my internet connection (my band width) is not slower than 63.48kb/s. I can achieve much more than that. In fact I have been processing clean energy tasks for some time. But when I am at home, on a slower connection, with more than one family member using the line then I can understand why it may sometimes measures a slower connection. But now I am back in a fast connection area. Surely the error should go away now and send me new work? So far no clean energy phase 2 tasks. I wonder with what regularity my band width is measured? Does anyone know?

So why not do this?
