Verizon PC-5740 EV-DO and D-Link DIR-450

2007-03-07T16:02:40Z

Verizon’s ad campaign centers around the concept of taking your network with you wherever you go. The PC-5740 and DIR-450 extends this to the Internet. I can slip the PCMCIA card into my Ubuntu laptop when I travel. Or my wife can slip the card into her WinXP laptop when she travels. Or if we are someplace where there is power but no WIFI, we can create our own WIFI network with the D-Link anwhere there is BroadbandAccess (Locator).

Ubuntu Edgy Eft installation:

Insert card into PCMCIA slot

Configure (this only needs to be done once):

echo "[Dialer Defaults]" > /tmp/wvdial.conf
echo "Phone = #777" >> /tmp/wvdial.conf
echo "Username = 0" >> /tmp/wvdial.conf
echo "Password = 0" >> /tmp/wvdial.conf
echo "Stupid Mode = on" >> /tmp/wvdial.conf
wvdialconf /tmp/wvdial.conf
sudo mv /tmp/wvdial.conf /etc

Connect and dial

sudo modprobe usbserial vendor=0x106c product=0x3701
sudo wvdial

Notes:

Verizon does not require a username and password, but wvdial does. Providing “0” as the Username and Password works.
If you have a problem whereby your connection drops after 2 minutes, comment out the following in /etc/ppp/options:
```
# lcp-echo-interval 30
# lcp-echo-failure 4
```

D-Link DIR 450 Installation:

Upgrade Firmware
Setup the PC-5740

Contrary to what the documentation states in step 5, you do not need a static IP on your computer, but you are welcome to set one up if you like.
In step 7, select Verizon - PC-5740
In step 8, Verizon does not require a Username and password, but the DIR-450 does. Entering “0” in the WLAN User Name, WLAN Password, and WLAN Verify Password fields works.

Connect either via 802.11 or Ethernet. I've tried Win/XP and Ubuntu; SMTP, ssh, and VPN.
