582n Wi-Fi Test Results
Quote from: Anotherone ...you really need to check whether they are pushing out more power, or whether it's purely antenna configuration that's making the difference.
Probably antenna configuration, RF receiver quality and signal processing. And obviously pushing out more power doesn't usually help - the device at the other end may receive it but will still be transmitting back at the same power level.
@Graham21
This thread is very interesting but can I ask a more fundamental question... what is the objective of this further testing? I think the original objective was to determine whether any of the routers returned as "faulty" were actually performing differently to a sample of known "good" devices. It seems the answer to that was no.
Beyond that, I'm unsure what further testing proves, other than that your wife is very patient
Quote from: Anotherone I wouldn't agree that pushing a bit more power doesn't help.
Yes, I agree with you. The point I was trying to make (perhaps not very well) was that cranking up the power at one end (eg the router) often doesn't result in better throughput or range, since you can't also increase the receiver sensitivity or the Tx power output of the other end. But yes, as long as there is still plenty of noise margin at the router's receiver it will help. Going back to the original question you raised, I understand the maximum output power allowed by ETSI in Europe is 20dBm (100mW) and most wifi routers use something around that level. My Asus router is set to 80mW (19dBm) but has much better wifi performance than the TG582n. I'm 99.9% certain that's down to a better antenna configuration (3x3 MIMO), good RF engineering and receive sensitivity, and better signal processing for handling both transmit and receive diversity.
Quote from: Anotherone just because Technicolor found no difference between the test units, that doesn't mean they perform as well as other makes/models.
I'm sure you know I'm not going to disagree with that!
But my question about the objective of further testing was a genuine one. It's a while since I read the rest of the thread, so I'm not sure if Graham is planning to test a variety of different types of router under (as near as possible) identical environmental conditions (useful!), or test the same set of TG582n routers in a variety of different environments (not very useful, in my own view).
Graham, if PN bulk purchased a better router you would obviously get a big discount. This could then be offered to your customers as a pre paid option instead of their using the TG582N. That then becomes a win, win situation as those customers who are at present dissatisfied with the TG582N will be much happier than at present. 
Re the router I returned to PN, it was situated in exactly the same place as my Asus replacement so I guess the speed difference will remain a mystery.

Ah, now I understand. However, your reply reinforces what I've said above.
Have a great w/e.
Quote You've replaced the 582n with a dual-band 600 mbps wi-fi router with 5 antennas! It costs £80 though

Quote from: gofaster I don't think O2 offer fibre though.
That's a valid point, also explains why I'm not seeing any wireless problem with my fibre connection --- it's no better than a good ADSL2+ connection.
I thought there was other complaints about the routers wireless performance (drop outs, range etc) or do they all revolve around speed?
