[clug] wireless access point on Linux box?

[Paul Wilson]

I have a linux mythtv box at the other end of the house where my wifi
is just on the edge of its signal range. Initially I was thinking I
could just find a wifi card to setup a new hotspot to extend the
range, but apparently I need a special wifi card with "AP mode" or
some feature which allows this.

is this still worth getting or just a cheep router?

any ideas?
