Just get a small 4 or 5 port Gigabit switch.

My new dilemma - I now have the one ethernet cable from the router to my office which has three computers (two of which are old and do not have WiFi).

What is the best way to connect them to the one ethernet cable? Can I keep the main speed for the one main work Mac and split the signal for the other two?

As Pheasant said get a 5 or 8 port gigabit switch, if you can upgrade the cable to 6a (not needed but worth doing in the long run).

You may find that the netgear wifi unit may work better in there. If you do decided got a 2nd mesh unit i think the office may be a good idea to put the 2nd mesh unit .

Might also want to consider connecting the “through wall” network cable directly to the Huawei ONT copper port.

Move the Velop unit into the office for the best WiFi (if that’s the primary WiFi usage area) and then hang the little gigabit Ethernet switch off the Ethernet port on the Velop for the other wired computers.

Sorry Taras I just re-read your post, I think I’m repeating your suggestion somewhat.

Could you not connect the ethernet cable to the ONT, then the router to ethernet cable in the office ?

i think all 3 of us have said the same thing of sorts.. The bigger thing as we don't know the cable length is to make sure the cat cable to the office is of good quality.

For me, backbone cabling - spend the money and for patch cabling in most cases you get away with 5e!

Cat5e everywhere. It's cheaper, more flexible, easier to terminate correctly than Cat6/Cat6A. YAGNI.

true about decent 6a cable ....... IT DOESN'T BEND (not that you should bend cable but i think you know what i mean)!

But it probably does blend.
