I know I set up my Linksys WRT54GL access point correctly because
my wife can do wifi to it on her Windows2000 laptop late at night or
early in morning.
It chokes during the day.
All I can guess is that the number of people doing wifi shoots up during
the day such that interference is unbearable for my little Linksys access
point.
I can't believe wifi is that susceptable and I'm at a loss as to what to do.
Should I buy a bunch of repeaters to push my signal above my neighbor's
interference? Is that all I can do?
That won't likely work. Normally the culprit is the Sony Location Free
TV which refuses to play nice with WiFi (it ignores backoffs and just
blasts packets). The fact that it goes down during the *day* would seem
to back that up (unless its some stupid nearby office. If it is, well,
hijack their connection if its that strong...). Normally residential
internet usage goes *down* in the day.
First, bump the system down to 802.11b *only*. That will force the
other routers in the area down as well. In addition, 802.11b is far
more robust.
Second, enable interference robustness. This tends to increase the
beaconing rate and decreases the packet sizes so that even when
interference hits, it doesn't wipe out as much.
Third, disable as much encryption as possible. Encryption requires that
none of the packets be missing before the decryption will work. In
the face of significant packet loss, it will cause a lot of unnecessary
retries. If you need encryption, it should be IPSec, https, ssh, etc.
which are handled at the client level rather than in the wireless.
Fourth, try to figure out which channel the stupid LocationFree TV junk
is on, and move out of it. Even moving to in-between channels which
have overlap (3 & 8) can be useful if you have a *really* crowded Wifi
space.
