The internal card is a wireless card, not a modem. A wireless modem would work, I'm not sure if you go a wireless router and hooked it up to a desktop and called from there if that would work, but sometimes if you do the math, DSL can be cheaper.

 

$cost of dialup service

+

$cost of 2nd phone line

=

more than the $29.99 SBC/Yahoo charges.

Its absolutely possible.

Take an external modem ($35 @ Compusa) + Dlink DI-714 ($87@ PCUniverse) = $125 solution for roaming your house in a dial up connection.

You need the EXACT model above, the DI-714P+ wont work.

Wireless just involves communication between the wireless device in your computer and the wireles capabilities of the access point. The method of connection to the Internet (or even if a connection to the Internet is involved) is irrelevant.

You will need an AP to handle the wireless connection. You need a modem to handle the dial up.

A wireless router with a serial port for connection to a modem will provide what you need. If you have difficulty finding a wireless router with dial up capabilities, a standard router with dial up capabilities and an AP will do the same thing.

i have an inspiron 9100 that is working great, but the wireless thing still isn't working out (i have only dial up service).  my salesman and his call-back guy talked to a "tech guru" 
and sent me the items i needed to have stand alone wireless internet with a dial up connection (a us robotics modem and a netgear 
firewall/router/access point)...   i'm just missing a step, i think.  can you run assess the following to see what i'm missing...

a)i connected the ext modem to the AP/router
b)the router recognizes the ext modem
c)the inspiron recognizes the router and the signal is "excellent"
d)i know that the ext modem works because i can dial through it (ie.phone line 
chain from inspiron to ext modem to wall)
e)i can't figure out how to make the inspiron dial through the ext modem... 
there is no way to connect the modem to the inspiron (via a serial port, etc) 
in order to install drivers for the ext modem... is this the step i'm missing?  
i believe that i can assign the external modem as the modem of preference for 
dialing (assuming that's what i'm supposed to do) once drivers are present in 
the inspiron...

please advise...  the forum has been so helpful up to now, i just need more specifics.

oh yes, get this... the last dell techie said this... "you can't have a wireless dial up connection 
unless you have another computer wired to the phone line and dialed in."  when 
i pointed out that that was the purpose of the ext modem he had no reply... 
argh.

I'm having a similar problem, but with a different twist.  I'm trying to connect my Verizon cell phone to my 9100

 and use it as an external modem to connect to Verizon's internet network.  This works perfectly on my 8100, but when installing

on my 9100 causes it to lockup.  Only way to unfreeze is to power down and back up again.  If you run across a solution to your problem

that might help with mine, i'd appreciate it.  So far Dell is telling me my phone is not compatible with computer, which I believe is a bunch of bull.

I think there's an issue with the fact that there are no obvious COM ports configured in the 9100.  Does your device manager list any COM ports?
