If you already have a Virgin connection in the office, you can move the router to here. My TV 360 boxes are both connected over Wi-Fi I never connected them to the router with the provided Ethernet cable. So I have the cable to the Virgin wall from both TV boxes only, no Ethernet to the hub also.
If you don’t have a Virgin connection already in the office you would need to get one installed by Virgin at £25. Using your own wires, whilst they sell them online can cause you a huge issue, Virgin cables are specially made nobody else in the UK makes the exact cables. This ensures your service works as expected, but the main thing also, is that Virgin to get fast speeds use some frequencies used for other things. Hence, Virgin make sure that things in your home cannot send interference back into their network when they set things up. If you were to DIY and introduce service issues for neighbouring customers you could very easily become extremely liable, and whilst I can’t say I’ve seen it happen, I’m sure all the customer visits etc will cost a pretty penny before they trace things back to you.
On another note, why do you need a wired connection in your office? This to me indicates more that your wireless coverage needs improvement, virginmedia have wifi pods and you can look into wireless mesh options such as google mesh (one of the better known but costly options), there’s so many much more affordable and just as good I am sure.
Avoid wifi “boosters” only get the mesh, and avoid “powerline” and “homeplug” as they use home wiring but are constantly fighting various levels of interference on your home electricity wiring as you turn on and off appliances and use more powerful devices such as tumble dryers etc. It’s not the same as a wire by any means. It’s variable quality and that’s not what you need when you are doing something that needs stability and predictability eg a video call or a screenshare.
If I give an example, I can get 650 meg on wifi using the virgin provided hub, in default setup, not a single setting changed from how it arrived on an approximately 1.5 to 2 year old iPhone, through a single wall (ie not in the same room). On a mesh my friend brought as a test I could do 400 all over the home by placing each of the mesh pods, strategically so they had line of sight or a single wall / floor between.
My teams chat today, capped out at 2.4 meg for 50 participants. My work VPN caps out around 75 meg, so I’d have zero advantage on a wire. I get over 75 on wifi always.
If I went wired, I’d also be tethered to a usb dongle, and these dongles have variable results in how they interact with windows. I had one a few years ago and if I moved the laptop / knocked the dongle it would disconnect (ARGH!)
You may be best leaving the wifi where it is, and getting the root cause issue resolved. I am guessing the main question is why are wifi speeds not satisfactory in the office? If your speeds are good but calls etc still break up, then your connection is not “stable,” ie it might be that your wireless is reflecting off metal insulated drywall, mirrors etc and whilst it has some “speed” the reflections of wifi cause, almost an echo which is awful for teams webex etc. Powerline seem to give reasonable speeds but when it comes to hosting a teams or webex, people complain, as the home wiring is ever changing in what’s powered etc, and even interference comes in form the grid to the home at varying levels overtime.
Another thing to consider l, moving your wifi to the office might fix the work issue. However, will a tv box work well if it’s connected from office to where your hub is now (assuming your tv box connects to hub over Ethernet). You may fix one issue and cause issues elsewhere in the home. If you did opt to move your wifi, say your living rooms at the front of the home and office at the back. A better move may be to get the hub in the middle (with as little walls etc in the way both ways). I’d still say, consider the wifi pods / a mesh setup you can buy online - there’s plenty now. I saw one on hotukdeals that was wireless AC 2600 (which is pretty good), with multiple pods think it was 4, for £89 not that long ago. Of course if you go down virgin pod route you get support from Virgin and it’s tried and tested with the Virgin service.
