WLAN Repeater Improving Your Router connection

By | January 21, 2015

Every wireless user has at some point had a problem with a wireless signal lacking in strength. This may be due to walls, floors, or other obstructions in the link – or because routers and client are simply too far apart. Such wireless connection problems in the home network can be solved by a so-called “wireless repeater”.
 
Wireless repeaters / range extender can give an improvement from a bad signal.
 
A wireless repeater is a kind of radio amplifier, which amplifies a weak radio signal from a router giving a more desirable connection.
 
Wireless repeaters / range extender
Instead of the term repeaters some manufacturers use the term “range extender”. Other terms such as a wireless bridge can also be used. Whatever they call it the main goal is still the same to give dead Wi-Fi zones in a home or business a good signal.
 
Most routers now come with a WPS button that can make for a easy setup to connect a range extender. To use WPS simply plug the repeater into a wall outlet, wait a moment, then press the WPS button on the repeater and then the WPS button on the router. Shortly thereafter, the repeater is connected to the encrypted Wi-Fi on your router. After doing these simple steps your wireless repeater should be ready to use.
 
Same or different WLANs
Some repeaters automatically copy the settings when connecting to a router, such as the SSID and WPA password and use this data for your own Wi-Fi, which in turn connect the clients. When a range extender does this it simply mimics the exact settings of a router and increases the signal. This has the advantage that all the clients in the home network, which already have the wireless access to your router, can connect instantly without any additional setup.
 
Anyone who uses a repeater as a wireless extension or bridging, however must understand data will not be transmitted as fast as a connection straight to a router. When transmitting data via the repeater theoretically available transmission bandwidth is halved.
 
The reason: When a extender sends a packet of information the packet goes first to the repeater, and then by the repeater to the client. During this time, the router must wait, because the transmission channel is not yet released. Only when the second transmission path from the repeater is completed to the client, the router can send the following package.
 
Basically a repeater will half the speed data can be transmitted. This has been a known problem for years and many manufactures are building much better repeaters to send and receive better signals.
 
Often this is not a problem with most devices such as a laptop that uses wireless N. It can send and receive at up to 300 Mbps. Most internet cable modems and DSL modems transmit at 20 Mbps.
 
Dual Band Repeater
Many manufacturers now offer repeaters that can transmit in the 2.4 GHz and 5-GHz band, this includes routers and wireless adapters. The 5 GHz band is especially interesting because it is not overcrowded like the 2.4 GHz band. 5 GHz doesn’t travel as far as 2.4 GHz but since there is less traffic, less data packets collide that can cause signal loss.

 
Tips for buying repeater
Reading reviews from real people is the best way to judge a repeater. Amazon or forums is a good place since so many other people that have bought a repeater will leave a review of it.

    Moving routers may be all well and good for folks with nice wiring systems in their homes, but I’ll wager that is a pretty small number of people. Many, if not most, of us have little to no choice in the matter of where we place our routers due to the entry of the incoming wires into our homes, wall placement and types of walls, concrete slabs instead of basements and lack of an attic in which to put wires … unless we want to turn our homes into Franken-houses with holes and wires coming out of them. My house is one such place, and I already have a new router, it just can’t reach upstairs into the master bedroom.

    Bad wiring in older houses makes it problematic for powerline ethernet also.

    That’s good to know. Are the houses brick? I can’t get 5GHz in the next house very well right now, but I don’t have the Asus you mentioned either.

    I actually have the same set up as you, only I’m using the 2.4 GHz for the backhaul because there is a storage building and trees between the two houses and the 5 Ghz band won’t connect. Neither house was wired for cable so we have 6 mbps DSL. Whenever I test at either house on either the router or extender I get about 5.8 mbps. I suppose the extender speed might be an issue if I had 50 mbps or faster internet but I’ve been extremely happy with my extender.

    What’s the best option for blasting signal to the next house over? It has to go through 2 brick walls, but after that, I’d like to have good coverage in both houses. Extender or new WiFi router or both?

      I have this setup between my house and my parents house. The two houses are approximately 150-200 ft apart. I use an Asus RT-AC66U on my parent’s side and the Netgear WN2500RP on my side. The Netgear is setup to connect to the Asus’ 5GHz band and I connect all wireless clients thru the 2.4 GHz links. I also was very selective about which channels everything runs on to avoid interference (it’s sad how many wireless access points around me are on Channel 6).

      With all this setup, I am able to stream a 3D HDTV movie with no buffering. I average around 13-16 Mbps even on wireless clients.
