How about adjusting channels settings, sm00thpapa? How about the rest of your devices working on 2.4GHz? Other electronic devices in your home (cordless phones, speakers and microwave ovens) that are on 2.4GHz might be interfering with the connection. It could be the environment since you mentioned that your firmware is up to date and it has been reset, right?
