<html><head></head><body><div style="font-family: Verdana;font-size: 12.0px;"><div>Hello,</div>
<div> </div>
<div>i have been trying to get my huawei e3276 dongle to work for almost a year now and have become frustrated enough to actually ask someone about it.</div>
<div> </div>
<div>the thing is that it does not behave like the ones i have seen working in posts on the Internet.</div>
<div> </div>
<div>All dongles i have read about can be brought up by issuing th AT command (i use 'cu -lttyUSB0' to talk to the dongle )</div>
<div> </div>
<div>
<pre style="color: rgb(0, 0, 0); font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: pre-wrap;">AT^NDISDUP=1,1,"online.telia.se"</pre>
<div> </div>
<div> </div>
<div>but in my case absolutely nothing happens, i just get an 'OK' reply</div>
<div> </div>
<div> </div>
<div>instead i have used the commands</div>
<div>AT+CGDCONT?</div>
<div>+CGDCONT :1,"IP","online.telia.se","0.0.0.0",0,0</div>
<div> </div>
<div>OK</div>
<div>AT+CGATT=1</div>
<div>OK</div>
<div>AT+CGACT=1,1</div>
<div>OK</div>
<div> </div>
<div>then i will get a fixed ligt on the dongle led and the command :</div>
<div> </div>
<div>AT+CGPADDR=1 will show an IP number in the expexted range for operator telia.</div>
<div> </div>
<div>dhcpcd wwan0 will time out</div>
<div> </div>
<div>after doing this, a look at the wwan 0 in ifconfig shows me this:</div>
<div> </div>
<div>
<div>wwan0 Link encap:Ethernet HWaddr 0C:5B:8F:27:9A:64 <br/>

<div> </div>
</div>
<div> </div>
<div> </div>
<div>i am using kernel 3.14.18 right now but will happily trade it for something else if needed</div>
<div> </div>
<div>does anyone have any ideas ?</div>
<div> </div>
<div> </div>
<div>here is an lsusb "portrait" of the device</div>
