5 out of 5 eggsI dumped linksys for Netgear!

Pros: I use dd wrt on this router and I love that I can mess around with settings and not have any worries about bricking it since dd wrt is still buggy. I can easily recover it in failsafe mode. With an old linksys (the purple WRT54G) I once had to short circuit pins on a chip to resurrect it from bricking-- and I never want to do that again!

Speaking of dd wrt, the original netgear firmware that comes with this router is actually beautiful and modern, and pretty customizable. I think there's also an easy setup version. I should have stuck to that, but I have been using dd wrt for years so I went with it.

I didn't really buy it for the dual band and I totally forgot about the 5ghz dual band broadcasting until I got a new phone and hooked up a roku player and I saw the name I had set up a while ago! 5ghz is nice and fast even though I live in a wifi congested area. I guess it's great for now since no one else has 5ghz.

Cons: I dont know if it's my computers or ddWRT but I always have problems with DHCP, even on my other netgear router and on my older linksys routers. I just set the gaming computer towers with static IPs and wired to the router and my wireless printer is also set to a static ip-- and I dont have any disconnecting.

Other Thoughts: I love these! I have this version, the WNDR3800, and the WNDR3500. The wndr3500 has been running for years and still going strong, and this version, that I have now had for a while, still up and running!

This is probably a dumb reason, but I stopped buying linksys routers when they started making them into weird rounded shapes. I like that these netgear routers are box shaped and the stands are detachable so I can stack things on top of them. I have my modem stacked on mine currently, and the other one I own had a skull put on top for weight since all the cables attached to it were pulling it off the shelf

2 out of 5 eggsDied after 15 months.

Pros: Worked great, fast, good range, easy setup, required very little power cycling (none in recent memory)

Cons: Died after 15 months of light usage.

Other Thoughts: Router worked great for 15 months. Then one day I could not connect, realized the router was making an audible buzz when the power was turned on. Range was very weak even from 1ft away, connection drops every 10min. The router is simply dead. I would have rated it very highly if it had lasted longer. I am replacing it with this: which may technically be a downgrade, but hopefully will last longer.

5 out of 5 eggsWorks great with OpenWRT

Pros: Bought to use with OpenWRT. I have two of these that have been running for 9 months at this point and they're going strong.

I upgraded from a WRT54GS and WRT54GL. These have more memory and are much faster.

I could be wrong, but as far as I can tell, you can't brick these. The installation of OpenWRT was pretty straightforward.

Cons: None

Other Thoughts: There is a header on the main circuit board with a serial port on it. I wired up a connector and mounted a DB-9 connector on the back panel. It works just fine, but the real purpose of this is to act as a serial terminal. If everything else fails, you can hook up a serial cable to the port and see what's going on as it tries to boot. You can also connect in to the console this way. As I said before, you really can't brick the router, so you really don't need this. I did it for another reason:

On my old WRT54GS, I had two serial ports, one of which I connected to a UPS. The WRT54GS ran NUT, and sent out network messages when the UPS was on battery. I intended to do the same with the WNDR3800. Because it only had one serial port, it will always output the console output to the serial port on boot. So, if the router reset, it would send a bunch of stuff to the UPS, changing the configuration of the UPS. Bottom line, the lack of a second serial port means that you really can only use the serial port for a console, or some device that can tolerate the output on boot.

2 out of 5 eggsConsider before buying

Pros: Easy to setup.
Worked fine for 6 months.
Bought for decent reviews & USB drive capability

Cons: Failed after 6 months.
Consider that this Netgear router has a 1 year warrenty, BUT they only provide free support for 90 days. So here's the catch. The router fails (it won't even respond to the "Factor Settings" reset). Support will not provide a return authorization unless you hook it up so they canrun diagnostics. But beyond 90 days you have to pay them for their support service. Also when you go to their support pages you get annoying ads popping up. One customer permanently gone.

1 out of 5 eggsNot happy with this router

Pros: None

Cons: It was hard to find a good, stable firmware for this router. V worked best for me. Router needed fairly frequent reboots to remain usable. After about one year of running, the 5GHz channel just stopped working. 2.4 GHz channel still works.

1 out of 5 eggsDisappointed

Pros: It has rebooted the 100's of times I've had to when the wireless locked up.

Cons: We have to power down and power back up the router at least twice a week. We're not bombarding the router with a bevy of devices - desktop, ipod touch and kindle fire.

Other Thoughts: Disappointed. Next stop is warranty or a new device.

5 out of 5 eggs

Pros: This router was a replacement for one that was becoming unreliable
It was very easy to setup and has been working without any problems since I put it in. Very easy to setup out of the box. I have it installed and up and working in 15 minutes.

Cons: none so far

1 out of 5 eggsJust doesn't work

Pros: it's pretty fast

Cons: I purchased this being a previously-happy Netgear owner. I'm running a Mac & PC home with Apple TVs, D-Link NAS, and multiple PCs. The Dual-band just simply filas to work. ie. my iPhones cannot connect to the 5-g Apple TVs, file sharing is impossible unless the modem is rebooted daily (seriously), and iTunes home sharing is non-existant. The Netgear support was not helpful in any way and simply sent me on a one-hour task of, yet again, flashing my firmware. My old Netgear wrt54 works perfectly - just slower.

4 out of 5 eggsStable and fast so far

Pros: dual band is really nice. 2.4GHz band is pretty saturated around here. so nice to run 5GHZ N.

Runs OpenWRT just fine.

Cons: 5Ghz radio signal strength shows about 20dbm weaker than 2.4Ghz radio. I still can connect to it though.

Other Thoughts: the premium features were not a bonus for me as I bought this to replace with OpenWRT, and it works great.

Not to mention one of the "premium features" was only a tril that expired in Feb (3 months before I bought it).

case design is a little odd. it works though and seems stable upright.
