Internet Connectivity impacted by multiple Acer S277HK displays

Hi - I am experiencing a unique problem which I have not come across before.  I have a very powerful desktop machine (i7 5930k, 32Gb DDR4 2133, MSI GTX 980ti, MSI X99 Gaming 7 MB) together with an Asus DSL-N55U modem/router. Until recently, my displays are 1 x Samsung 28" UHD + 1 x Acer S277HK (27" UHD). I currently use the Samsung and 1 Acer together in a dual expanded display set-up and wanted to add ther 2nd Acer S277HK so as to make a 3-way expanded display. The motherboard and the Graphiocs card have no problem with the 3rd monitor. I bought the 2nd Acer and connected it to my machine. However, whenever I power the 2nd Acer up, my internet connection fails - all 3 monitors display perfectly, with no issues, but my internet connection fails.

 

So, to be clear - if I am running my machine with just the Samsung + 1 Acer display, I have no problems - my DSL internet connectivity is perfect - fast download and upload. The moment I switch the 2nd Acer on (i.e. 3 displays operating), my internet connectivity fails, and the modem cannot resolve itself. Has anybody ever come across this before?

 

As I say, I've been building and operating PC's for 30 years, and have never experienced this type of problem. It's like there is an IP conflict on the Acer displays, but that's impossible, surely?
