Does the job

It does the job and the brand name is very reputable. However I have noticed that it isn't as well made as it's previous model. The plastic is very thin and does not feel very durable. It is also more expensive than the previous one it has replaced.

Can I put two Ethernet cable in the two slots thing? Would that let me use the broadband with two different computers?

1 Answer

Hi Jess,

Thanks for using Argos Q&A.

I can confirm that the Masterplug UK Compact Double Equipment Adapter will split your single telephone socket in to two separate telephone sockets.

The best way to get two computers to connect to your broadband router would be to check the back of your router for extra Ethernet ports as most broadband routers will have more than one for this exact purpose. Alternatively, if you have WiFi you can connect multiple devices to your WiFi and can achieve this with non-WiFi devices by getting a USB wireless dongle.

I hope this helps,

Can I put this in the wall and put the broardband line and the telephone in it? At the moment I think the only telephone socket in the study is being used by the broadband line, and I would like a corded speaker phone there, rather than a wireless phone in there. I have virgin wireless cable broadband.

Would this adaptor work with the Caller Display / Caller ID ?

I have the Caller Display / Caller ID service, the numbers of incoming & missed calls are shown on the telephone. When I used other brand of double adaptor, I found the telephone numbers of incoming calls cannot be displayed. Please let me know if this adaptor could work with the Caller Display ? Thank you.
