If I could find a way to do it, I would literally kick myself in the ass for not having taken the plunge earlier, but getting a Cingular WWAN card was an excellent decision.
In my defense, I have been able to use both my current and previous phone as modems, so my need wasn’t quite as dire. But such usage merely ensured that a.) both laptop and phone were continuously low on battery power, b.) that I was limited to the speed of the phone itself, and c.) that I couldn’t be online and use my cellphone simultaneously.
I tried to get one of these cards a week or two ago here in Maine, but Cingular is apparently transitioning away from the Sierra cards to ones provided by Option and they didn’t have any in stock. Although the newer cards apparently function perfectly well under Linux, I wanted to reward Sierra’s commendable decision to provide at least some support for Linux, so I waited until I was in San Francisco last week and picked up an Aircard 875.
Couldn’t be happier with the decision.
After a two year contract, the cost of the card was $50 with rebate, and the price for unlimited service is $59/month rather than $80 because my existing cell service is with them. That sounds expensive, until you consider that hotel wifi is often ~15/day, so if I spend more than four days per month in a hotel not buying their wireless it pays for itself. And regrettably, I spend more than four days in a hotel just about every month – let alone airports. Ultimately, this should dramatically reduce my connectivity expenses, and it frees me from having to pay the protection racket fees of local wifi providers everywhere.
In case you’re wondering why I chose Cingular’s service over Verizon, it’s primarily because of the coverage here in Maine. I can get EDGE speeds (two or three times dialup) here with Cingular, while Verizon phones usually can’t even make a call. In major markets like San Francisco, I connect at considerably faster rates: I was clocking mid 700′s down, mid 300′s up regularly this past week in San Francisco. Not a cable modem replacement, but more than adequate for my needs on the road.
Depending on where you travel and spend your time, similar offerings from Sprint, Verizon and so on may be better alternatives for you. I can’t comment on those, but feel free to do so if you’ve had good or bad experiences.
On Windows, the setup experience is very straightforward and takes about 10 minutes. On Linux, the setup experience is slightly less so, but not terribly complicated at all. Here’s how you do it on Gutsy Gibbon, the latest iteration of the Ubuntu distribution:
- Drivers: check to see whether or not you already have the Sierra drivers present by open a terminal and typing:
modinfo sierra. If you get something that looks like this:
description: USB Driver for Sierra Wireless USB modems
author: Kevin Lloyd
you’re good. Proceed to step two.
If you don’t, head over here to get the driver and follow Sierra’s instructions for installation.
- Scripts: this is the tricky part if you’re not a Linux person, but really all it amounts to is cut and paste. Seriously. So if you’re a Linux person, just follow the instructions here (many thanks to ITGuyonline for both figuring that out and posting his scripts). If you’re not a Linux person and need a bit more hand holding, do this.
In your open terminal window, type
sudo nano /etc/ppp/peers/cingular. Paste this:
connect "/usr/sbin/chat -v -f /etc/chatscripts/cingular"
user "[email protected]"
Then hit CTL-O to write the file.
sudo nano /etc/chatscripts/cingular. Paste this:
ABORT BUSY ABORT 'NO CARRIER' ABORT VOICE ABORT 'NO DIALTONE' ABORT 'NO DIAL TONE' ABORT 'NO ANSWER' ABORT DELAYED
'' "ATZ" 'OK' 'AT+CGDCONT=1,"IP","ISP.CINGULAR"'
CTL-O to write.
sudo nano /etc/ppp/chapsecrets, and paste this:
"[email protected]" * "cingular1"
That’s it, you’re more or less done.
- Connecting: plug the card into the PCMCIA slot on your machine and wait for the blue power light to steady and for a pale red light to activate next to the 2G or 3G symbols. Once that happens, type
pon cingularinto a terminal window and you should be off and running. Once the pale red light turns from red to blue, you’re connected. If you want to watch what it’s doing, open up a terminal window and type
sudo tail -f /var/log/messages.
There are ways, apparently, of connecting this process to GUIs, either KPPD or Network Manager – Miguel did that here – but I’m too lazy. The command line is fine. What I would like, for situations where I’m on a train or some such, is to get UMTS Monitor working for signal strength purposes and such, but it doesn’t seem to play nicely w/ my card.
While the arcane nature of the above procedure may confirm for some of you the wisdom of Walt Mossberg, who determined that Ubuntu isn’t suitable for mainstream users (a claim that I partially agree with – more later), it speaks to me instead of community strength and growing corporate interest. All a matter of perspective, I suppose.
