I start Mozilla which loads my homepage then I clicked a link on my page.
I've tried different links on different attempts with the same results.
I've also tried keying in a url manually. ie.

I should note that I only connect at 33,600 with this hardware even though
this is a v.92 modem?

Here's my modem config:

I'm using ATZ as my int. string but someone suggested AT&F. But I can't figure
out why connects are so slow? My Zoom 56k on my desktop gives me great connects
using the same phone line and ISP. So I guess the problem is with my
laptop/pcmcia modem? But I've been trying different things (KPP, pppconfig, XP
with different settings) with no luck.

I've also tried this modem with XP (same laptop) and I get hung up on also.
The logs show compression and error correction is disabled. (Under XP
that is.)

Thanks for the response and any ideas. Oh yeah, the modem manufacturer has
yet to get back to me.
