Hi, i have frequent disconnects on my RE450 Range Extender, 
i did all the troubleshooting indicated by the customer service and i still continue to have the problem, 
Below are some troublehsooting that was done as indicated by CSR.
Place the RE next to the main router. 
Update the firmware ( as directed from download center). 
changed the channels on the main router.  

I called up the customer service multiple times and i was indicated that i will get a call back in the next 2-3 Hours and this had never happened.

The CSR whom I was talking indicated that she will be writing an email to near by service center for replacement  but wont be able to do as it was a saturday. 

These discussions are not getting recorded and turns out to be a pain point everytime when i need to call up customer service, ending with no solution and the call is getting over indicating that i will receive a call in the next 2-3 Hours and this never had happened. 

is there someone to look around this and provide me a solution?
