SWMBO had complained about her Laptop, in her Study, occasionally losing contact with our WiFi Router.

As the Router is at the other end of the house and festooned with Ethernet connections, I couldn't relocate it and any amount of twiddling with the Antennae had no worthwhile effect.

So I took the easy way out and defaulted her connection to my neighbour's Router instead.

Until I twigged that the flaky performance of our Printer (also in SWMBO's study) might well be due to the same issue.

Well, after a bit of research, I came across cheap Chinese WiFi Repeaters (More expensive and no doubt more robust ones are available from Netgear etc, but folk might recall I am a Yorkshireman) so I took the plunge and lashed out just over £8 for this:

Found a spare mains socket in SWMBO's study, plugged it in, pressed WPS button, dashed into the Drawing Room and pressed the main Router WPS key and lo, I had a nice strong signal throughout the entire house.

Has been operating for a month now and it hasn't set fire to the house.

Don't worry unduly, these things happen when you get older..........

Hi G, I replied originally but the restore wiped it. I have a few questions; does this repeater create another wireless SSID for you to connect to or does it use the same one as your router on a different channel...? Did you have to connect this repeater to the original router by the Ethernet cable or is it a proper repeater that connects to the router wirelessly? If it's the latter then I am pretty sure - but could very well be wrong - it halves the available bandwidth on the wireless network.

And as I replied originally, it was my supposition that the connection to the main router was wireless and that the Ethernet port on the remote unit is for connecting to devices, such as a printer, which have a LAN RJ45 connection but are not wireless themselves. I further posited that the SSID was cloned so that handover is seamless.

T then said I was pretty much right.

Halving the bandwidth? Don't know about that but speed of connection decreases with distance so there will inevitably be a drop-off due to the master and slave being apart but that is undoubtedly less than the very poor signal from just the master.

The last paragraph is all new.

If you start from scratch (or reset the device) and use WPS, it nabs the base SSID, sets itself to the same Channel and adopts the same security method, including the key - all without the need to connect up by Ethernet.

ie True plug and play

But, of course, you can get into it manually, via a Browser and Ethernet cable (WiFi works if you access it after a Reset).

Therein are Windows 8 style menus where you can configure it however you wish, either as a Repeater or as an Access Point.

I did actually later amend the SSID so I could use the excellent WiFi Analyser Andriod App. and check around the house what the comparative signal levels were from Router and Repeater so I could easily manually change Network if I wished (Of course, some newer fangled "Devices" will change seamlessly on their tod).

Paul is righter than the rightest right thing.

As for Bandwidth, I have read that myself but in practice it has no discernible effect. Speedtest results are identical and I can stream HD telly even with other devices online. And my Broadband is 10Mbps up and down (I chose to drop from 20Mbps as I didn't need it and saved a fiver every month!)

Thanks Paul and G, I missed your replies - clearly wasn't quick enough!

I realise that the speed drops off the further away you are from the WeeFee point but there's a technical reason that the bandwidth available is essentially halved. So, on a 54Mbit link, the speed would drop to 28Mbit.

Nabbed from a site...
Wireless is shared bandwidth and is half duplex. Unlike a wired connection that has one path dedicated for transmit and another dedicated for receive you only have 1 frequency in wireless. Means you can't be sending and receiving at the same time. So if you were to use a repeater on the same frequency it will indeed cut your bandwidth in half. It is actually much worse since there is no way to prevent 2 devices from talking at the same time only a method to correct it after it happens.

Good news is most repeaters allow you to use 1 channel to talk to the remote location and another channel to talk to your PC. You still of course will have your repeater competing with your pc's in your house but it is the same as use your shop PC in the house directly. All the PC compete with each other. The key reason people do not notice this is the PC;s are not actually active at the same time. If you have a number of machines streaming video...especially highdef from media servers you can really see the slow downs.
Either way, it seems like quite a useful device - especially for the price! I should get one for the in-law's whose WeeFee is atrocious in most points of the house.

Was the previous 20Mbps service symmetric? i.e. 20 up and down?

If the connection around the house is faster than 10Mbps, and it probably is, then doing a Speedtest to the Internet will inevitably show no reduction.

@CJ: Indeed - well worth a go.

Love mine!

@PaulR: To be honest, I can't remember! (All too common a state, I fear)

Where did you get it fom Tivu. I'm using an old Dlink router to acheive a pretty similar thing but to be honest the results aren't brilliant so for £8 its well worth it to shut my teenage daughter up :D

The Bay Of Fleas - wait one and I'll find the seller (There are many, but he was cheapest, UK based and sent it within a day)

Some SAT-related hardware.
My Location
N-E from Riga
I have installed in several sites TP-Link TL-WR841N , it is not repeater by default but has bridge mode in original software. Not so difficult to set it up. So, couple of SAT-receivers, stationary PC and TV set are connected by wires. And, of course, it also disperses additional wireless network in the apartment. It is hanged behind the TV and asks for no attention.

No satellite stuff for the moment (aside from a 43cm minidish that was on the house already), Samsung SyncMaster T27B550 Smart TV & Monitor, and a few computers...

My D-Link DIR-615 reaches halfway down the garden through 10" thick stone walls, about 80ft or 25 Metres, what's wrong with your router? o_O
