As reported, the Idea E1550 shows signal and the vendor manager claims “connected” on Ubuntu 10.04 but upload/download remain at zero. has offered carrier support and correctly pointed to mode‑switching as a common cause. The checklist below is a compact, practical troubleshooting path that isolates whether the stick is exposing a real modem (PPP) interface or only the vendor “connection manager”/storage device.

Quick diagnostics (run with sudo):

lsusb
dmesg | tail -n 80
ls /dev/ttyUSB* /dev/ttyACM* 2>/dev/null
tail -n 200 /var/log/syslog | egrep -i 'ppp|pppd|modem|option|usb'
ifconfig -a
ps aux | egrep 'ppp|wvdial|pppd'

What to look for

  • If lsusb shows the device but no /dev/ttyUSB* nodes appear, the stick is still in storage mode and needs mode‑switching (as noted by ).
  • If /dev/ttyUSB0 (or similar) exists, a PPP session should create ppp0; check ifconfig -a and syslog for pppd negotiation or authentication errors.
  • NetworkManager sometimes reports “connected” to the vendor GUI while no PPP link exists. Running sudo wvdial (or using a manual pppd invocation) exposes the actual AT negotiation and error messages.

Minimal example wvdial snippet (replace <APN> and device path):

[Dialer Defaults]
Modem = /dev/ttyUSB0
Phone = *99#
Username =
Password =
Init3 = AT+CGDCONT=1,"IP","<APN>"
Stupid Mode = 1

Other checks and cautions

  • Confirm the APN and dial number with the operator before changing settings.
  • If the stick stays mounted as a mass storage device, use a mode‑switch tool or the vendorless drivers; blacklisting usb_storage is a last resort and may affect other USB devices.
  • Collect lsusb, dmesg and syslog output to identify vendor/product IDs and exact driver behavior; those logs show the definitive reason for zero traffic.
