3.0 out of 5 stars DD-WRT = WIN; Wireless power = Lose, September 26, 2012
This review is from: Buffalo AirStation HighPower N600 Gigabit Dual Band Open Source DD-WRT Wireless Router (WZR-600DHP) (Personal Computers)
I really want to love this router; and outside of the wireless signal strength I adore it.

It comes with built-in dd-wrt, albeit slightly customized for buffalo, which I use for some very advanced configurations: multiple public facing IPs, complex port forwarding, QoS, etc. This could be achieved with other dd-wrt compatible routers, but none of them come with it pre-installed and ready to go; sometimes there are special caveats.

Wireless AP configuration is also awesome, there are 2 individually configurable interfaces for the 2.4 and 5ghz bands. Each interface can be configured with its own SSID, WPA or WEP or whatever security you choose. Additionally, virtual interfaces can be added in case you want to present more than 2 SSIDs, and the virtual interface can even have its own security configuration!

All of these positives are counterbalanced by a heavy negative: the wireless signal strength is absolutely terrible. The maximum power I am able to get out of the router are 19dBm and 20dBM for the 2.4 and 5ghz bands, respectively. In terms of signal range, I used to keep all of my routing equipment in a closet in my garage. My old netgear wrt-54gr sat in this closet and was able to provide a strong signal throughout my house and covering my front yard and back yards (1350sqft, single-floor home on a 5000sqft lot). This 600DHP can barely penetrate walls on either band; in one of my bathrooms, which is under 20ft away and passing through only 2 or 3 inside walls, I am unable to get a signal at all. The backyard also has maybe 75% less coverage than I had before.

Fortunately, I have my house completely wired with cat6 drops and a configurable patch-panel in my garage. So, I am able to move the router to a more centrally located placement in my family room which improves the coverage situation somewhat.

Because of the above, I have so many mixed feelings about this router. If I had to do it again, I would research more dd-wrt compatible routers to find one that has better TX power. But for the convenience of having dd-wrt pre-installed, I am utterly lazy and pretty happy with my purchase.

There are other features which I haven't bothered using, but I think would be very useful for those who want to take advantage of it: USB hard drive support (plug in a usb hard drive) for basic network-attached storage, a DLNA media-server for streaming to network connected media players (lots of new TVs support this) and easy-to-use wifi setup through WDS and AOSS

Do you not have the option in DD-WRT to increase the TX power? On my old WRT-54G (that I'm looking to replace soon), there's an option in the Wireless tab in the Advanced Settings, there's a field to change the TX Power anywhere from 0-251mw. It defaults to 70mw, but I keep it at 100mw and it provides good coverage across my house. This router seems to be good for me, but if you can confirm that you can boost TX power in it, then I would feel more comfortable buying it. So I would appreciate a response!

The option for TX power is there, but it does not get accepted. Basically, no matter what you do, the tx power remains the same.

I just changed mine and it worked fine. Did you save it and then apply settings as well?

I'm thinking about picking this router up but I have a question. Is there a way to have some devices in my house connected through a VPN that is configured on the router and some devices not? From your review and what I know about dd-wrt I might be able to have 2 separate SSIDs with one using the VPN connection but is there an easier way? VLANs or something?

Thanks for that tip cause the default on mine was 20! it sucked bad, as P.F. Nguyen stated, mine would not hardly broadcast accross the house. I changed the TX power to 251 and now it works fine. Thanks again.
