4 out of 5 eggsGreat router but usb printer support bewarned

Pros: Easy setup of the router itself, very good range. I have it hooked to my cable modem and to a switch. Set up a guest network.

Cons: Set up my Brother HL-2040 laser printer to the usb port on the router. After a couple of months it would not print correctly. Sometimes it would printer blank pages one after the other. Turns out there is a very very short approved printers list.

Other Thoughts: If the USB printer support is a deal breaker, check the approved printer list.
If your printer is NOT on that list, don't count in it working.

5 out of 5 eggsAmazing

Pros: Super fast and great range I can go outside my house and about 50 feet from the house and still have a full signal ni loss of speed so that's awesome but you better set up a secure connection bc I'm pretty sure my neighbors have a great signal for my wifi as well.

Cons: None at all

4 out of 5 eggsGreat Router

Pros: -Runs cool
-plenty of options

Cons: -signal strength was ok, but not as good as i thought it would be
-price happened to drop a few days after i got it.

Other Thoughts: The only reason i am giving it one egg less is mainly due to the signal strength...its still great and i can connect from my bedroom to living room with about 4 strength on most of my devices but sometimes i see a dip below half. Regardless, performs rather well and was a step up from my linksys router.

5 out of 5 eggsOutstanding!

Pros: I have been a die hard Linksys fan for years (WRT-54G callout). This is the first router I have ever owned that I did not have a need to modify firmware. For stock firmware, this device provides every option you will generally need for customizing operations...short of DD-WRT firmware options (which I have not had a need to try on this unit yet). I replaced a Linksys 300N and have noticed remarkable improvement in reception (I live in an older house with a lot of metal in the walls). I especially like that you can add custom antennas to boost reception (amazing difference over stock antennas which are decent enough). Range for my wireless is easily doubled (have not tested max distance yet).
ASUS also thought of the underside cooling as the stand lifts the bottom up a good two inches for better airflow. They did an outstanding job on this device!

Cons: This guy runs hot. This thing does run hot so you will want to make sure there is proper ventilation for the unit. Not hot to where you can't touch it nor am I worried of fire or whatnot...just use your common sense here.

Other Thoughts: Some have complained about connecting printers to the USB port. I am not sure why router manufacturers have not been able to fix these issues but remember, these are network devices so your printer's comm requirements may many of my IT brethren, I HATE printers.

4 out of 5 eggsgood

Pros: Samba server, built in VPN client and server, no need to change bios to wrt to use a vpn. FTP (9mbps), and DLNA streams 1080I flawlessly, 2 USB 2.0 ports to share your hard drive across your network.

Cons: day 3 it flaked out and i had to restart it. but since it has been fine.

5 out of 5 eggsAwesome router!

Pros: Was worried this wouldn't make a difference over my TP-LINK TL-WDR3600 Dual Band Wireless N600 I replaced. But wow - what a difference! Now I get maximum bandwidth from my time warner connection and get coverage all over my 2300 sq ft house. No crazy flashing leds.

Cons: Maybe kinda expensive but definitely worth it

4 out of 5 eggsvery happy

Pros: Very happy with this router after a DD-WRT flash of my RT-N16 messed up my UPNP from my WHS 2011 server. Options are great and it's been fairly reliable....except for one thing. Pleased with firmware and ease of use. Don't feel compelled to flash to DD-WRT. Everything in the menus works quickly.

Cons: I have to reset the router whenever I power off my printer....took me forever to figure out why my network printer would sporadically function. Probably a pro for some people, but I have to add each MAC address to both 2.4 and 5Ghz lists.

Other Thoughts: USB shared drive didn't work with my Sans Digital box....don't know if the problem is unique to a box like that since it's not exactly a simple external drive.
