USB Modem Support - Sierra Aircard 250U 3g/4g (Sprint)

[ Edited ]

Hello Everyone,

I'm trying to get this aircard to work and i wanted to see if anyone else had or has some pointers. I'm using a RAP5, but i dont get any visibility when the AP boots up when i try to go to 192.168.11.1 i get nothing.

 

I'm following as best as i can the directions posted here...

 

http://www6.sprint.com/downloads/linux/pdfs/Sprint_Mobile_broadband_Setup_Guide_for_Linux_1.4.2.pdf

 

and these are the commands that gets pushed to my rap...

 

provision-ap copy-provisioning-params ap-name "RAP5WN"
provision-ap installation indoor
provision-ap no external-antenna
provision-ap usb-dev "0x11990301"
provision-ap usb-dial "#777"
provision-ap usb-tty "/dev/ttyUSB0"
provision-ap usb-init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 ISDN = 0"
provision-ap usb-type "sierra-evdo"
provision-ap no 4g-usb-type
provision-ap usb-user "user"
provision-ap usb-passwd "user"
provision-ap server-name jim.*.net
provision-ap master jim.*.net
provision-ap ap-group "RAPs"
provision-ap ap-name "RAP5WN"
provision-ap no syslocation
provision-ap remote-ap
provision-ap reprovision ap-name "RAP5WN"

 

I've tried multiple variations of the init string, regular ol' up atz, no user/pass.

 

I'm confident in the dial string and the device ID. I have telnet turned on in the rap system profile but i can't ever hit anything when it comes online while it's looking for the sprint connection. eventually it times out and comes up fine on the ethernet.

 

Any tips for being able to watch it boot? telneting into it and passing at commands similar to consoling into a 70 and breaking into the console?

 

Thanks for the ideas.

-Jim

What is the software version on the controller?

Did you ever find a resolution to this?

Re: USB Modem Support - Sierra Aircard 250U 3g/4g (Sprint)

have not found a resolution.

 

workaround has been having my mac "dial" the sprint card and bridging the network jack with the sprint card and then plugging in the rap to the mac and then connecting the macs wifi to the rap.

 

it's dirty but it works. I'd really love to have this work natively since the company pays for the sprint card.

hi James

 

not sure if you typo'ed that or not, but the usb-tty should not specify /dev in it, just put ttyUSB0 and the RAP will (blindly) prepend the /dev - which means for now you may be having /dev/dev/ttyUSB0

 

regards

Re: USB Modem Support - Sierra Aircard 250U 3g/4g (Sprint)

Finally had some time to start looking into this again. Jeff you are right i was using the /dev/ prefix, so i removed it and turned on telnet to the ap to get some output. So far i'm getting the rssi on the cellular side so that is encouraging but the pppd log shows an apparently dislike my init strings. I've tried both ATZ and AT+CGDCONT=1,"IP","INTERNET.COM" as listed on some of the ubuntu forums for sprint card support.

 

Here's what i'm currently provisioning the RAP5 with...

 

provision-ap copy-provisioning-params ap-name "RAP5-1"
provision-ap installation indoor
provision-ap no external-antenna
provision-ap usb-dev "0x11990301"
provision-ap usb-dial "ATDT#777"
provision-ap usb-tty "ttyUSB0"
provision-ap usb-init AT+CGDCONT=1,"IP","INTERNET.COM"
provision-ap usb-type "sierra-evdo"
provision-ap link-priority-ethernet 100
provision-ap link-priority-cellular 110
provision-ap server-name *.net
provision-ap master *.net
provision-ap ap-group "Split-RAPs"
provision-ap ap-name "RAP5-1"
provision-ap remote-ap
provision-ap reprovision ap-name "RAP5-1"

 

 

here's some output from the controller

show ap provisioning ap-name RAP5-1

show ap debug usb ap-name RAP5-1

Re: USB Modem Support - Sierra Aircard 250U 3g/4g (Sprint)

I went through all ten of the ttyUSB interfaces on the rap this evening. Every one of them return the following garbage except for 0 which returns good rssi, so i'm pretty sure i'm using the correct port with ttyUSB0.

 

ttyUSB1-9

hi James

 

sorry for delay I have been OOO and just saw this. Seems now that you fixed the ttyUSB up, you do need to set the usb init string back to the correct value for EVDO (you have set it to the what we would use for sierra-gsm at the moment). i.e. from your original post you had it set to this, which is likely the correct value provision-ap usb-init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 ISDN = 0" try that, with the corrected ttyUSB0.

 

regards

Re: USB Modem Support - Sierra Aircard 250U 3g/4g (Sprint)

Nope. Still getting rssi from 3g, but the new <old> init string errors out and pppd still dies... I was trying the other init string because some ubuntu users were reporting success with it on this card as i was googling around the net. Any other strings to try?
