Connecting to Different APs

At hotels, motels, airports, and many other
sites I am unable to "associate" on many occasions.
These sites are all infrastructure, no password,
no WEP, no apparent, to me, reason why I should
not be able to "associate." Some of these sites have strong
signals, i.e., greater than 70 percent. At the same time
time I am able to connect to some APs with very weak signals, for
example, 20 percent signal strength. I use a LinkSys USB
adapter which will connect almost when no signal is present.
Could someone educate me as to the reason that I cannot
connect to these very strong signals on the one hand,
and can connect to very weak signals on the other hand??
Thanks

Perhaps they are using MAC filtering.
