@Lee Do you also have a Cisco gateway? If not, you may want to start your own topic.
As for wireless stopping, could you explain the symptom? If you mean your wireless stops working but wired doesn't, then yes, that is a problem with your wireless router. What happens when it goes out? Can you see the SSID? Can you not connect? Error message? Does it ask for the passphrase? Or was your post just a rant?
