in the hope that a newer model equals better I've ordered the AC600. Have tested it and unfortunately it is not as it should be.
Test: N standard router with 2.4 and 5 GHz. Router distance 5 meters. 2 router test TP_LINK N900 and D655 DLINK
At 2.4 GHz, the 150 MBs are never displayed at full signal strength. Moreover, not even come through half the power.
At 5 GHz Max 150 Mbs at full signal strength display does not even begin to is what is promised.
I can not recommend a purchase.
NOTE: Product description is wrong here!
2.4 in n MAX 150 MB
5 in n MAX 300 MB
