(moderation:
Looking for recommendations about fixing a BOINC problem that affects SETI@home, Einstein@home, and climateprediction.net.
No new workunits are being successfully downloaded, I get truncated workunit files and error reports like this:

The E@home project also send me links to this URL for logs:
I earlier aborted several dozen SETI@Home workunits that were not being processed...there's a message about "trust" there, but my system was working OK in October when I shut it down, I'v recently restarted it, but on a slower network connection.

Hi
Can you give us some details about your connection to the internet and network? It's a bit difficult to make a diagnosis without any information on the infrastructure.

I'm using the "usb0" interface tethered to a cell phone. Works fine for HTTP access to the web, though I've sometimes seen as much as 30% packet loss when doing pings. Right now I'm seeing 0% packet loss.
I have BOINC configured with "low" bandwidth settings, since T-mobile is limited my upload and download rates. After my billing cycle starts again I can bump these up.
Currently, I have a 10Kbyte max download rate, 15KByte/sec upload rate.
Network device: usb0
Hardware address: 26:a2:b3:9a:4c:aa

Up the speed and instead set
)
Up the speed and instead set a cap on your computer or on the mobile with an app. HTTP doesn't do too well over TCP when both sides do bandwidth limiting and there's a high amount of packet loss.
You will still occasionally see the messages, but workunits should be plenty enough to not make it a problem anymore.
Otherwise you may have to reconfigure the TCP stack on your computer for highly lossy connections and that could have a negative performance impact on normal (cabled) internet connections on that machine.
Also, some carriers allow both proxied (default) and direct internet connections. The proxied connections cut the connection if it hangs for too long while direct connections work pretty much like normal internet connections do.
Note down the proxy used in your internet settings on the phone (if any) and try to delete it to see if the internet is still working.
BOINC in particular has a setting for working with some of those bad proxies that don't send you what they receive - I forgot the name of the setting, though.
