The Archer dongle I received earlier failed to connect on the 5 GHz band so I returned it. Though this is more expensive than the TPlink T4U V2 Archer dongle which is cheaper by around Rs 300, but you get what you pay for. So skimping money on dongle will waste the money I am spending on my broadband. In speeds test for the same network the maximum download speed on b/g/n dongle is around 30Mbps which 3 times slower to the 110Mbps speed I get using this AC dongle. This dongle is rock solid in its connectivity to the AP with very good RSSI.A 5GHz AC standard dongle is about 4 times expensive than the comparable b/g/n standard dongles, but if you are on a fast broadband (mine gives 110mbps download speeds) then using a slow wifi dongle will kill your real internet speeds. The wifi where I live is very noisy with frequent interference due to a lot of neighboring networks. This dongle works very well with full strength connectivity to my router at 864 Mbps which is the best you can get for this standard.
