I live in panel-house (cube with concrete walls, reinforced with steel) which is part of bigger block. Recently I have successfully setup wifi network through the flat, but at the recieving end I have really bad reception (-80dB). One problem is the environment and the other problem is interference with other wifi's in the block. The radio spectrum is really overflowing...
I would like to move the AP to better position in flat, but the problem is, it would mean to lay ~12m of UTP cable which would be also mean reconstruction of the flat, to properly hide the cables.
So I was wondering if there is any better option. I'm considering two options listed below:
a) Use power network adapter. This thing is plugged into electric outlet and provides ethernet connection between 2-N places. The manufacturer says it can reach 300 meter, but I'm a bit skeptical about this number. The thing is, that our flat has only aluminum wires, roughly 25 years old... My another concern is security.
b) Second option I'm considering is to use WiFi repeater. I have drawn a simple diagram od flat layout:
The green AP would be the position of the repeater.
What is your opinion on the proposed setup options? Thanks for any feedback.
UPDATE: Some more details. The router I have is Tp-Link WR741ND, running N WiFi, 2.4 GHz. The router is locked by my ISP, so I cannot really tinker with it. 5 GHz is unfortunatelly not an option, because the PCs are laptops without 5GHz capabilities. Plus there are smartphones on the network which doesn't have 5Ghz either.
Answer
I've messed with everything you've talked about before, and I can make a few suggestions to how to go about it.
When homeplug works it works - but when it dosen't, you're out of luck. I'm using 15 year old copper wiring, and it works reasonably well, but I tested it before I went all in.
I strongly recommend testing with the cheapest kit you can find (I went with a ~75 dollar pair of 200 mbps Homeplug AV adaptors from aztech), then building out if it works - I've added a 500 mbps gig-e switch to my desk). Once you're sure it works, in typical configurations, you'd want to go for units with passthrough - this lets you actually use the plug, and isolates noise from systems that are plugged into that connector (so its perfect for places where you have PCs with SMPS - which produce noise).
Connections between paired devices is encrypted (AES 128) and should be reasonably secure. They come with a default private network name, so you may want to change that.
My network, simplified (I have another AP... and so on ) now looks like this
The two routers have different SSIDs and cover different parts of the apartment - I have complete coverage loss at a specific beam, and as such a repeater wasn't an option. Since the secondary router is not a DHCP server, the systems are on the same subnet. In theory this setup should let you run an AP in a different channel, or band, or even both.
