Hi All
Does anybody have any idea what could be happening here?.
I have a laptop DELL INSPIRON 3511 and everything works just
fine, literally everything. even the iwlwifi0.
But in order to use my full 600mbps, i dont use the wireless
but a TP-LINK USB ethernet connected on "ue0"
ugen0.6: <TP-Link USB 10/100/1000 LAN> at usbus0, cfg=0
md=HOST spd=HIGH (480Mbps) pwr=ON (200mA)
but something really strange is happening .. everytime i open
the chromium e do a speedtest (could be speedtest.net or any
other) , at the end of the test the eth interface dies .. it
changes from full-duplex to half-duplex/no carrier and the
only way to get the internet back thru ue0 is by rebooting the
whole thing.
not even a "service netif restart" does anything
if anyone has any ideas why is that , would be appreciated
Hi,
I think it some new features they use in the USB data protocol
which we don't support. Check the Linux code.
Between does:
usbconfig -d 0.6 reset
recover the device?
--HPS
Hi,
Search for axge on bugzilla:
I suspect you are using this chipset:
Try:
usbconfig show_ifdrv
To know for sure.

Hi Hans,
actually the driver i use is not agxe (i thought it would be by
the time i bought the usbcard)
this is the module im using
if_ure.ko
and thank you , yes, reseting the usb entry with your command
worked just fine.
i got the internet back after doing this
usbconfig -d 0.6 reset
do we have a bug here then?
thank you
--tzk
oh, i forgot to mention that the ure driver freezes not during the
download test but in the middle of the upload, always
dont know if that helps
thanks
--tzk
Hi Ivan,
Yes, there seems to be problem there. I need to look at the driver.
Maybe it is simply sending too much data, than the device can handle!
--HPS
Hi,
Try lowering this constant to 8192:
sys/dev/usb/net/if_urereg.h:#define URE_TX_BUFSZ 16384
Then recompile and install if_ure:
make -C sys/modules/usb/ure KMODDIR=/boot/kernel all install
--HPS
You can also try other values, like subtracting one.
--HPS
hi Hans,
it worked but with a cost.
i tried 8192 and it works 5 tests (5 speed tests in a row). freezes on
the 6th.
then i tried 4096 no success
then i tried bufsize 2048 and its working now, i did several tests in
a row and the internet keeps working just fine. but i noticed that the
speed also dropped.
with the same server , testing on windows, it goes like:
600 download / 300 upload
and on freebsd with 2048 bufsiz it goes like:
300 download / 150 upload
so it worked with a cost like i said, i had to give up half of my
bandwitch
what do you think ?
and thank you again

Hi,
Can you try this instead:
usbconfig -d X.Y set_config 1
X.Y are the numbers after ugenX.Y
Then it will use a different driver.
--HPS
Hi Hans,
After the usbconfig -d X.Y set_config 1, the interface doesn't work
anymore, how can I undo this?
Thanks
Ivan
usbconfig -d X.Y set_config 0
or
usbconfig -d X.Y reset
Did you check dmesg?
--HPS
hi Hans,
i had to reboot my router but i got my interface back running.
and i have good news
after that, im still using the buffersiz 2048 and this time i got 600mbps
download /300 upload just like that.
these 2 things were not related i can see.
i guess thats it , looks like its solved.. i will keep monitoring here , but so
far so good
thank you a lot as always
