Conclusion: For those looking for an affordable, dual-band wireless-N router, the ESR600H's relatively low price is still not low enough to justify its poor 2.4 GHz performance, weak range and some software issues.
Pros: Some software improvements since last firmware. USB 2.0 port support printer and external storage. Very good performance at the 5 GHz band. Relatively affordable.
Cons: Poor 2.4 GHz performance. Some interface issues. Long reboots for settings changes. Significant drops in throughput with distance.
