I think I might have misunderstood your cable running into your room. If this is just the cable from the ISP and you are looking for cheap and cheerful, then below might work: 802.11n (where wireless performance and speed is not your main concern) https://www.amazon.de/NETGEAR-WNR2000-200PES-300Mbit-LAN-Ports-schwarz/dp/B00S9DKS02 https://www.amazon.de/TP-Link-TL-WR940N-Anschluss-Glasfaser-Modem-schwarz/dp/B00VVHONRM 802.11ac (still not fantastic performance, but slightly better than above) https://www.amazon.de/Netgear-R6120-100PES-Dual-Band-Gästenetzwerk-kostenfreie/dp/B071HWVV5J https://www.amazon.de/dp/B07GVR9TG7 These are just examples. Without knowing your priorities on cost vs performance.

It sounds like you already have a router, so you probably only need an access point or something similar to extend the wifi you get from your existing router. If that is the case, something like this might be what you want: https://www.amazon.de/Netgear-WAC104-100PES-Business-802-11ac-Wireless/dp/B01LQ23DU4 It has a few ethernet ports for your wired and you can setup your own SSID for your room for your own wifi. Can can set it up with the same SSID and password as your existing wireless (make sure to use a different channel), however note it will not allow for proper roaming.

Yeah I find the Orbi system really good - even using the wireless backhaul, however wireless is so dependent on the environment that it's hard to say it will work for you. My house is timber framed, so that helps. Based on the square footage I would say a router and 2 satellites would do the trick, but you know your house layout better than me. I think RBK53S is the SKU you would be looking at. Or you might be able to get a better deal buying separately.. I don't know.

The ideal solution would be if you are able to run an ethernet cable from the position of your router to the locations you need to boost your signal. For example I have a Netgear Orbi mesh system, but am actually using ethernet backhaul instead of wireless. There are two advantages to this from my point of view: 1. The ethernet backhaul means faster and more reliable network (though I must say when I tested the wireless backhaul it was actually almost as good). 2. By using a mesh solution it allows for roaming between the router and the satellites to work properly. I used to have a router and access point (again connected by ethernet) but the roaming and the hand off between them did not work very well.

Here we go again.. Getting the vacuum to the PC to make sure it's in optimal condition.

Both repeaters and extenders (unless they have a separate radio for connecting to the client and for broadcasting) will half your throughput. If you were to do it properly you would get a dual/triple radio extender, however this would be outside the budget.

What might be a better solution is to buy a dedicated repeater/extender, then when your internet goes down, you turn on your hotspot and then repeat the signal from your phone. Maybe something like this: https://www.amazon.com/NETGEAR-AC750-Range-Extender-EX3700-100NAS/dp/B00R92CL5E However I think you are asking about an actual WiFi card for your PC? If this is what you are saying then you need to decide between internal or external. https://www.amazon.com/TP-Link-Archer-T6E-Wireless-Technology/dp/B016K0896K or https://www.amazon.com/NETGEAR-A6200-WiFi-USB-Adapter/dp/B00FKD6OC0

If you plan on gaming, you might be better off to get a 802.11AC WiFi adapter to take advantage of the lower latency that that allows over 802.11n. A lot will depend on your router as well.

Does this AP have a repeater mode? What you will need to do is to connect the repeater to your routers wireless. Perhaps the issue is that the placement of your AP is outside of the wireless range of the router?

Is the access point connected to the router via ethernet or are you trying to do a wireless bridge?

So well deserved. Well done mate!

Glad to hear it. Any issues running the cables into the different rooms?

IMO you generally get what you pay for up to about $500 mark for consumer grade routers. After this the returns on your investment go down. Generally anything under $100-150 will be fine for non techies and anyone that just goes on FB. The only thing to consider for these lower end routers would be wireless range and coverage. One advent over the last couple of years that has been fantastic for home networking is mesh wireless networks. They allow easy placement of a router and multiple "extenders" for want of a better word. The advantage they have is great coverage and usually good roaming. Were you looking at anything in particular?

You'll have loads of bandwidth and you are adding no real latency by adding a switch. it might be more helpful if you could give an idea of the topology you are looking for. A good place to start would be the physical distribution of the PC's you want to connect. Are they all in the same room?
