I have just recently switched to Plusnet Fibre. I have noticed that my router is making a loud buzzing/hissing sound - it’s in the same room as our TV which can’t be avoided. I have seen various threads regarding this and it looks like I seem to be having the same issue as others. I’ve disabled 5ghz for now which has reduced the noise partially only. However, I need to use 5ghz therefore please can I get a replacement router sent to me? Are there any details you need from me in order for you to do that?
