RE: Sprint Novatel Ovation U720 USB phone very slow on Fedora

I finally got a chance to try this and used the wvdial thing vs. kpp. It works great! It was pretty dang fast.
Now I have one more dumb question. I have it set as a network interface. So, in order to get to it, they have to click system > network > administration > network and then they activate the interface. When they do that, it asks for the root password. Is there no way to activate that without supplying the root password?
The guy was taking the laptop out of town. I did not notice the problem until 3 minutes before he left and did not have time to dig into the answer.
Any ideas?

I am trying to install a Sprint Mobile Broadband USB Modem (Novatel Ovation U720) cellular USB phone on a Dell laptop running FC7 test4. I found a variety of instructions on getting it to work with FC6 and applied it to my install and it works..sort of.
I have the laptop set to dual boot with XP. I first made sure it worked under XP. It does and it extremely fast. I then did the install on FC7. After issuing "/sbin/modprobe usbserial vendor=0×1410 product=0×2110". Once that was done, the modem appeared as /dev/ttyUSB0 and /dev/ttyUSB1 (someone said they think the latter is a management and diagnostic interface; the former is used for the PPP connection). I was then able to use KPPP to set up a dialer connection. I started the dialer and bam it connected. Once connected I see this:
# ifconfig

The only problem is that it is slow as glue. When I click on a website, it takes 30 to 90 seconds to respond. Once it actually starts pulling data, it seems a little quicker but then bogs down when trying to go to the next website. I manually changed the "serial" bit rate in the configuration files to the same way it was set in XP (230400 bps) but that did not help.
In XP, the IP is set as follows:
Connected to NDIS:

Does anyone have any ideas?

That is an IPV6 address.
Can we see your: /etc/wvdial.conf ?
It is usually a matter of the 'correct' initialize/dial strings.
No K bashing intended here:
wvdial is a package and required for dial up networking done with
system-config-network
However, none of that matters to the argument at hand, its just easier
for me to explain how to watch things.
With syslog set to debug you should be able to see the entire handshake
and any error messages or unexpected results.
We use both EVDO and GSM based cards on trucks. The computer on the
trucks run FC6. :)
----X----
#!/bin/sh
# add debug to syslog
ed << _EOF /etc/syslog.conf
/local7/
a
# Debug
*.debug /var/log/debug
..
w
q
_EOF
touch /var/log/debug
chmod 644 /var/log/debug
service syslog restart
----X----
Now you can:
% tail -f /var/log/debug
and watch the entire conversation during a dial up.
What you are looking for are the strings that begin with sending the
modem 'AT'.
At the least you should see 'ATZ' and or 'ATM0' or something like:
'ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0'
These are all sort of generic initialization strings.
Unfortunately for use we cannot see what Windows driver is sending to
the modem, but it will contain something like these.
This forum expresses similar issues as you are having ...
http://www.evdoforums.com/thread3308.html
The speed issue is explained here:
http://samat.org/weblog/20070127-high-speed-cellular-wireless-modems-in-ubuntu-linux-6-10.html
"Switching from 1xRTT to EVDO is not automatic (though I believe EVDO to
1xRTT is). On Windows, I believe this is done manually by the connection
manager software…"
This means that a dial up initialization string (AT command) needs to be
added, or that a command has to be sent on the command channel (ttyUSB1)
to set the mode.
Using the above degug data you should see a response from Sprint as to
which mode is established when connecting.
The PCMCIA versions of similar cards default to EVDO mode (thankfully),
but this one may not.
Beyond this, its not clear to me yet how to change the mode.
Hope this helps a little.
Good Luck!
