is it feasible to pull LAN cable from 1st floor to ground floor, by inserting the cable into the power cable conduit? I'm worried about not able to push the LAN cable through conduit bends.
has anyone done that before?

I haven't bought LAN cable yet. but don't want to buy and end up not able to do it.

For normal cat 6 ok ,if your house really have conduit but as industry std not recommended as the electrical cable may interfere with the network cable although it was shielded.

Big No No.
Separate conduit ok.

big NO. You don't mix network cable with electrical cable.

You can cross them at some point but not run along with them.

Why don't run mesh since is only one floor difference? Mesh nowadays quite powerful already.

I use tplink powerline adapter, works very easy, almost plug and play.been using a few years, somerime need to switch on/off, maybe 2 or 3 times a year. But very stable, good speed for noemal use. Latency high so not good for gaming.

I did 2 cables DIY.

Pull first and hold with double sided tape. After that, fix the casing with VHB (very high bond) double-sided tape. This tape only can get from 3M. So strong that pulling out the casing will also pull the paint out.

My contractor pulled fiber + converter at both side in those electric cable conduit. No issue for few years already.

By right you should NOT have high voltage and low voltage in the same conduit due to performance and safety reasons

But it is doable if you insist

Fiber is non-conducting (electrically) so that is still ok. But copper runs the risk of interference as well as any damage to cable(s) leading to current leakage onto the network cable, which is both dangerous as well as destroying your equipment.
