Questions and Answers C-15
Why doesn’t x2 technology work for me (connecting at
33.6 Kbps or lower)?
If you are getting a connection rate of 33.6 Kbps or lower,
then you are getting a V.34 connection instead of an x2
connection. If this is your situation, one of the three required
components for an x2 connection (as listed in the previous
question) is lacking.
Why am I not connecting at 53 Kbps?
Phone lines limit V.34 and x2 connections. These connection
speeds are decreased by line noise in analog phone signals.
Since there is an analog portion in an x2 connection (between
your home and the Central Office) this will limit the
connection rate. Many times, x2 connection speeds will be in
the range of 42 Kbps to 47 Kbps. The highest connection
speed according to FCC regulations should be 53 Kbps.
Miscellaneous Questions
What can I do to upgrade performance?
„
Increase system memory (see “DIMM Upgrade” in
Chapter 5 for guidelines about increasing system
memory).
„
Increase video memory (depending on the video upgrades
available for your system).
„
Clean out the files in the Windows\Temp directory on the
hard drive. If you access the world wide web in Internet
Explorer, clean out the files in your
Windows\History
and
Windows\Temporary Internet Files
directories. These
files are created automatically during normal usage of the
computer and should be deleted periodically to free up
hard drive space.
