Building home network with wifi roaming

Question

I live in a new apartment building which means a lot of concrete. The internet (fiber) enters the house at the beginning where the modem is hooked up to my Linksys WRT320N. From there two cables run through the house:
1 to the home office, where two computers are connected through a switch
1 to the living room, where the Xbox, blueray player are connected through a switch
I also have a wifi network running from my WRT320N, but as it is at the beginning of the house, there are some black spots in other parts of the house. I tried to fix this with a Netgear repeater, but that keeps disconnecting.
What I want to do know is place a second linksys device in the living room at the end of the already existing cable that will also broadcast a wifi network, but I want this to be exactly the same wifi network as I already have. What I want to achieve is that I can walk from one end of the house with my iPad, streaming a video, to the other end of the house and that I always stay connected to the internet and that my tabled just picks up the strongest broadcaster, basically the same as with a mobile phone.
I hope this makes some sense and that somebody can tell me what device I should buy.

Answer 1

As the scenario that you explained according to that you can go for RE1000 depending upon the distance. The RE1000 is meant to extend the range of an 802.11n network. While the device has the ability to extend the signal for a traditional 802.11g router, still it is not recommended. The reason for this is because the RE1000 is built to extend 2.4 Ghz 802.11n signals which use MIMO as well as other advanced technologies, if attempting to extend a G network you will not achieve the desired performance because it is not optimized to extend standard 802.11G signals.
Remember that the RE1000 will only extend the 2.4Ghz frequency. Meaning that if you have a router that is dual band you can only use an extender on the 2.4Ghz channel. The 5 Ghz channel does not currently have an Extender available for it. Since some dual band routers have the ability to select which frequency you want activated. Always make sure 2.4 Ghz is enabled if you are having troubles configuring.
Lastly and most importantly, remember that in order to get the best performance from an RE1000 you need to place the extender in an area where you still have at least 50% signal strength to your router when you place it in the final location where the RE1000 will be used. To configure the RE1000 you will need to login to the UI after you have put the RE1000 in the final location to verify the signal strength below is a reminder about signal bars and what they mean as a reminder
For ALL configurations you should have between 2-3 bars of signal at the very least. If you have less we will need to move the RE1000 closer to the router. You can also check the status on the status page of the RE1000 as well. On the status page it measures both Signal Strength and Signal Quality. If either set of bars is red you must move the RE1000 closer to the Router.
