Just got this laptop from a friend. Acer ASPIRE 1400xc with smartlink 56k modem. Used it but got frustrated coz' of its crawling speed. I installed antispyware, adaware and antivirus softwares and got rid of all its bad stuffs and caught a lot of it too. Now I can't connect to the internet coz' of "no dial tone" message. It's running with XP Home Service Pack 2. Don't know if the port is enabled, it is not displayed on the device manager. Uses Com 3. Any help would be appreciated. Thanks.What kind of anti-virus software do you have? My grandpa had the same issure, and I soon learned that the anti-virus was blocking access to the internet. ALSO, make sure you have a phone wire running to the internet.This error message is related with phone line. Check it very carefully...
No Dial Tone
and here's the Test for you.Tried uninstalling my antivirus software (Norton Internet SECURITY), still no luck. I think I its got something to do with IRQ. It uses IRQ 11 and COM 3. From modem properties resources, I can't uncheck the "use automatic settings" box preventing me to change the IRQ channel. Is there any way around to force my modem to use IRQ 4?Contol Panel/Modem/More Info and see what happens.

I have no idea what operating system you are using. Did the modem work before? Did ANYTHING happen to it - power surge, etc.
