That sounds like a big risk, I am connected through Wi-fi now but the signal is not great and I get disconnected from time to time
That is quite expensive, I'd rather run a line on the floor and get shouted at by the landlord
Hey Arex, nice diagram, clearish problem statement. You have 3 options:
1. Upgrade your (possibly crappy cheap chinese) wifi kit. Someone suggested Ubiquiti Amplifi, a good choice, made in USA. You didn't tell us what wifi kit you currently have (we just hope that it is not Ubiquiti), so we cannot provide anymore speculative feedback.
Solution tech rating: 7/10.
Ease of implementation: 9/10. It just works. Beautifully.
Solution cost: 2/10 (more is better). The Reserve Bank don't like no 'merican imports.
Tech skill required: 9/10 (you need to be able to read and understand english).
Will the wife like it? 10/10 She will just love it.
2. Run powerline extenders. This is possible, depends on your needs in your study. You didn't give us any throughput requirements for the workstation in the study, which would help in telling you if it may work or not (to around 65% accuracy, depending on your electrical layout). It will also provide forumites fertile grounds for much anger, banter and mirth over the next 3 weeks, and also feed a few trolls.
Solution tech rating: 5/10.
Ease of implementation: 8/10.
Solution cost: 5/10
Tech skill required: 8/10 (you need to be able to read and understand chingrish).
Will the wife like it? 8/10. She will think you are a genius.
3. Run ethernet cable. You can do this two ways: in the roof, or along the walls. If you have a lady friend, both will require trunking (not her, the cable jou rowwe bliksem).
Solution tech rating: 9/10 for CAT-5 UTP, 10/10 if CAT 6, but -1 if you don't earth both ends.
Ease of implementation: 6/10 for walls, 4/10 for roofjob.
Solution cost: 6/10
Tech skill required: 3/10. You need to be able to crimp cables and/or estimate (to the centimetre) cable lengths. Aside from a crimping tool, for roofjob you need a ladder, a camping headlight, dexterity, good balance (no fatties) and common sense to only walk on the thick branderings.
Will the wife like it? 5/10. It depends. If you mess up the trunking, you will have to do it again. If you leave a 500x500mm gaping hole in the ceiling, and possibly break a femur, you are screwed.
I hope that this guide helps, considering the info available.
