Wireless configuration - Modem/Booster - multiple log ins?

Hi all,

Hopefully somebody can explain this setup for me, or point me to a tutorial if necessary.

I'm not overly familiar with ways to configure my internet setup.

I've just switched providers, and I've now got different logins to a booster (although I think it's a router, the install tech confused me a bit).

Anyway, I now have:
1. Modem set up in my basement, connected to RJ45/CAT5e to 3 rooms in my house that were already set up (but not in use). Leaves me 1 spare ethernet port to run to a gigabit switch to hardwire my devices in the basement (PS3, Nexus Player - I'll get a microUSB to ethernet adapter, and likely more devices to come). I can connect devices via Wireless to the modem, but it's limited to 2.4G.

2. A 'booster' is connected in my living room via the CAT5e to provide wireless signal (I think the terminology changed and this is simply a router). This puts out both 2.4G and 5G signals. It also has 2 additional ethernet ports if I want to wire anything up.

3. 2 bedrooms (wired to the CAT5e) have nothing connected at the moment.

I have 3 different access points available to me when I connect via wifi. A standard name (which I believe is the modem in the basement) which doesn't clarify frequency, I believe 2.4G and 2 other networks, which are the same name, but have the distinction of either 2.4G or 5G at the end of their names.

Most of our devices can't take advantage of the 5G signal (my girlfriends desktop, our iPhone 5's and the PS3). - although my newly build computer can!

So, my questions:
1. If a device is connected to 5G, but cannot take advantage of newer technology, would it make sense to connect these to the 2.4G signal instead? Would it be better/worse/no difference?

2. One of the bedrooms is at the other end of the house, and while wifi signal is better than our previous provider, it's still not perfect. Would I see a benefit attaching another router to the CAT5e in that bedroom and connecting to wifi in there? Would this create yet another "available connection" to sign in to?

3. With multiple available connections (modem, router x2 signals & potentially a 2nd router in the bedroom), is there a way to configure my devices to connect to the best suited connection?

4. I'm pretty sure this doesn't work, but for the bedroom, can I run a CAT5e cable from the wall directly to our smart TV? Or would it need to pass through a router?

Thanks!

#1 -- If it will connect to 5Ghz, then it will have the best bandwidth, but the shortest range. 5Ghz doesn't penetrate walls as well as 2.4Ghz.
#2 -- A WIFI access point is what you want rather than another router. A router will work, and can be configured like a wireless access point.
#3 -- There is no easy way to get a device to connect to specific WIFI sources other than choosing them manually or having much more expensive WIFI hardware (commercial).
#4 -- Yes, you should be able to run a cable from the wall to the TV and it should work.

Thanks kanewolf!

Just a couple of follow ups:
1. Glad to hear. I've got the phones hooked up to 5Ghz (the phones can 'see' then, the girlfriends desktop does not - I assume it all depends on the wifi chip in it). Would you recommend 2.4Ghz for the bedroom then? Realistically it has to pass through 4 walls to get there.

2. Thanks, I'll look into access points (I've heard of them, but don't have much knowledge there).

3. I expected as much. Would it work (say on phones) if I just signed into all the available connections? Kind of like how it picks up a wifi signal if you've been connected at somebodies house/work etc? Or would it not work because there's so many connections in range?

4. Thanks! Funny, the one thing I thought for sure wouldn't, should. I'll test that out this evening.

If the access point allows multiple SSID names, as many do, set one of them to a unique name. Then for devices that you want to connect only to that point, set up only the unique SSID on the device. This is particularly helpful for non roving devices like printers and game boxes.

Fro example if the common SSIDfor the network is Bartynet, call the unique SSID BartynetDen.
