We have an installation where we use ATT for the isp on DSL. The DSL goes to the DSL Router, where the next node is a Apple wireless router, and the rest of the house is wireless.
Unfortunately, every day we loose wireless to router confusion on a daily basis. Sometimes only temporarily, sometimes bad enough we have to reset everything.
We are running five computers off the wireless sometimes. Would that cause problems? is it just the nature of wireless to get lost like this?
