I've been having some wlan issues here off and on for a while and it seems
like it has been getting worse. Where I'm at I can see about about 7 APs,
including my own. Sometimes a few more, sometimes a few less. Typically
the other APs are on channels 2,6 (several), 10 and 11 (several). I have
tried various channels trying to avoid the crowds, usually 8, 9 or 4
(since the 6's and 11's are closest to me, at least in terms of signal
strength). I am sitting about 8 feet from my AP right now and still
getting 15-25% packet loss! I'm receiving about -57db from my AP and -79db
from the nearest competing AP, so its not clear to me that the
interference is necessarily coming from other APs. One other thing to
note, sometimes I start getting a lot of drops (usually when I'm further
away from my AP) and resetting the AP (d-link, 802.11g) seems to "fix" the
problem for a while.
Any ideas on what might be causing the poor performance? Is this normal
performance for this amount of congestion? Is this due to a cheap AP?
Is there anything I can do to track down the interference or make
adjustments that will increase my reliability?
