Hi bpnola,
We do offer wifi extenders in our Cox Retail Stores, it would be hard to recommend a specific brand or model as they are all universal adapters and will work with any router. The following link will help you locate the stores in your area, you would just need to enter your zip code in the search field. Click here - http://ww2.cox.com/aboutus/neworleans/contact-us/cox-centers.cox. Our reps at the retail stores will be able to answer any specific questions you may have in regards to the equipment that are in the stores in your area.
