Two or three years ago I installed a Trendnet TEW-432BRP
(802.11g) wireless router to link upstairs with downstairs
(and out to the Internet via wireless router with antenna).
This home network works reasonably well about 28 days
a month; the upstairs unit (Belkin 802.11g wireless card)
occasionally reports Very Low Signal, sometimes no signal.
When on line without trouble download speeds are OK, e.g.
50 Mb in 10 minutes or so.
Just lately performance has been poor just when I wanted
to update the income tax software . . . Would a newer
router (perhaps Wireless N) give better performance?
