N300 WiFi Range Extender(EX2700) is generating annoying, high-pitched noise

[CHSimonsen]

Hi. My new N300 WiFi Range Extender is generating a very annoying, high-pitched noise, which is hard to ignore. 

Has this problem occurred to anyone else? Is it normal? Are there any solutions to this problem? Should I just return the product?

Any help would be appreciated - Thank you so much!

If its new, I'd return it for a replacement. If you search google or these forums, you find lots of posts about routers/extenders making a high pitched noise. Sometimes its a bad power supply, sometimes a bad cap, and sometimes its within specifications. If you can hear it and it bothers you, I'd exchange it while you still can.
