Thread: EVDO speed problem in Ubuntu 9.04

-

hi,

recent convert ubuntu. after struggling m$'s pathetic windows vista long, decided switch allegiance ubuntu , must not disappointed.

installed ubuntu 9.04 on laptop , out-performs vista mile. i've run in problem. based in india, , use bsnl (india's national carrier) evdo internet connection. uses zte ac8700 usb modem connecting.

device evdo on laptop using userserial drivers , wvdial. put stupid mode 1, , baud rate 921600.

works alright, speed capped @ 62.5 kbps; it'll go 62.5 kbps never beyond that. whereas @ same laptop, @ same place, when connect win xp, speed goes upto 100-110 kbps.

due usbserial drivers, reportedly have max buffering capacity of 60 kbps (at many places i've read usbserial drivers in ubuntu 9.04 don't have problem)? , if yes, how change airprime drivers?

please help.

regards

nitin

i think facing same problem soon, when receive sprint novatel ex270 expresscard in mail week, , try on dell 15n ubuntu 8.10. sprint pdg guide linux says max thruput limited 599kbps usb drivers. live in oregon , california.

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
