Thanks for sharing your experiences with E4200 v1 vs RT-N
56U and E4200 V2!
I kept the RT-N
66U because it outperformed my E4200 v1 to a realtively significant degree on 2.4 GHz in terms of signal strength and because the E4200 V2 actually performed slightly worse overall (in any case no better) than the V1 on 2.4 GHz wireless in cNet's tests and, correct me if I am wrong, also in Tim's wireless throughput tests.
I can dig up my E4200 v1 numbers (to be compared to the RT-N66U vds Amped R1000 results I posted a few weeks ago).
In any case, I am glad the V2 is working so well for you and that you found the 4200 V2 was better than the RT-N56U which, in turn, was better than E4200 V1 and hence V2 is working better than the V1 for you.
I find it interesting (I am sure your numbers are real by the way and not doubting you at all) that you got such great signal strength * given the tests run by cNet and SNB that show them to be close in terms of throughput and overall actually seem to favor the V1 on 2.4 GHz if I recall correctly (cNet's overall 2.4 GHz performance results certainly seemed better in the V1 than the v2).
Obviously throughput and signal strength do not necessarily directly correlate (i.e. a medium signal on one router may still support a higherr throughput than another router with a strong signal - in fact I noticed this with my Asus versus Amped - the Asus had a stronger signal one room from the router than the Amped, but the Amped [in that room] had the higher throughput of the two routers).
If you use LAN Speed Test (easiest and quickest since you only need it to be running on the client, albeit not the most accurate by a long shot) or if you have more free time use a tool like jperf, you could run actual throughput comparisons between the V2 and your Asus RT-N
56U.
* I assume you compared the signal strength [in RSSI[ of the v2 to your V1 as and RT-N56U as well and not just comparing transfer rates? )
By the way, 130 MBps and 300 MBps sound a lot like link rates not actual throughput.
I personally like the included advanced features of the RT-N66U (even if I am not using many of them just yet).
Transmit power adjustment could come in handy if I ever move to a smaller dwelling where I might actually want to lower it a tad.
My RT-N66U was actually cheaper than the V2 by about $20 (even though money was not a deciding factor in my selection - I was willing to pay more than the V2 or other competitors if the performance was good enough, which it was in my 3 location throughput and signal strength testing).
Also the Asus RT-N66U has fixed a bizarre "missing Netflix cover art" issue that happened while using the Amped. That alone was worth the price of admission of the Asus since I was going to return my SmartTV and just use the Blu-Ray player's Netflix app since that one did not have Netflix issues even while using the Amped (despite using the same Netflix menu layout as the TV).
I love having Netflix built into my TV (which for the price paid was competitive with other non-Smart TV' sets and also included the thin size of LED technology, 1080P, 120Hz and Dolby TruSurround HD) and not even having to turn the Blu-Ray player anymore.
Anyway, I am starting to digress too much...
