#2274 closed enhancement (fixed)

add Junxion patch to usbserial to improve HSDPA throughput

Reported by: arnoldsvincta@… Owned by: nico
Priority: normal Milestone: Barrier Breaker 14.07
Component: packages Version:
Keywords: usb-serial Cc:


Following the testing of numerous HSDPA cards on the wrt54g3g with the standard kmod-usb-serial package, I have noticed that while the connection between me and the mobile tower is >1Mbs, my actual throughput is restricted to a relatively slow 460kbs. I suspect this is due to the hard buffer limitation of usbserial to 64k as explained here:

Please consider adding the junxion patch explained in the link above to the usbserial package to enable effective use of HSDPA cards/usb modems.

Thanks Nico and the team for including the 2.6 patch and accept my apologies that the previously mentioned diff did not suit the 2.4 source.

Please find a tested patch for the 2.4 branch for inclusion.

This patch is more suitable for the wrt54g3g due to its broadcom wireless.
