5 out of 5 eggsExcellent low cost option

Pros: Out of the box is easy to set up
Upgrade the Firmware!!!
Best option is DDWRT firmware upgrade, but note this will void you warranty.

Cons: shipped firmware is junk.
Upgrade the Firmware!!!

Other Thoughts: If you want a low cost wireless router with decent speed and ability to upgrade to DDWRT firmware, this is it. If you want to go to the next level, check out the RT-N16

5 out of 5 eggsIf you have a WiFi adapter with RaLink chipset, run. Screams with Realtek (RTL8192CU) chipsets.

Pros: Very fast performance with latest Firmware. Works like a champ with Realtek-based (RTL8192CU chipset) WiFi adapters.

Cons: Epic Fail with RaLink chipsets.

Other Thoughts: For a while I was having nothing but trouble with this Asus router for months. My speeds would fluctuate. No amount of factory resetting or firmware tweaks did the trick. That was until I replaced my useless Tenda N300 WiFi adapter that had an RaLink chipset in it with one that used a Realtek chipset, specifically RTL8192CU. I bought a cheap one for $7.50 on *that really big auction site*. The difference is night and day. No more corrupted downloads, no speed degradation, no more wonky problems. My Asus router rocks once again.

Asus recently put out version beta of the firmware and it *dramatically* improves the speed of the GUI and time it takes for reboots and changes to be made in the system config. With the new firmware, getting up and running took minutes with the new QIS. Prior to this, I often had to reboot my cable modem and then the Asus router for things to work. Now it just works. One caveat, going from the 2.0.x firmware to 3.0.x firmware will wipe out your settings and you won't be able to use your 2.0 setting backup file to import it into the 3.0 firmware.

I am now convinced this is a quality Asus product that I am very happy with. Wish I would have known it was RaLink's fault, and not Asus. If you have trouble with this device, check and see if you're stuck with a WiFi adapter that is RaLink-based. Heaven help you if you are. You can always try going to station and see if you have newer drivers. Don't know how well it works with Atheros chipsets though. Try the 3.0 firmware, it's great.

5 out of 5 eggsVery satisfy. Got a second one.

Pros: Sorry, everyone but this is one of the best router I have ever own. The speed is great. But all great things don't have to come to an end just purchase my second one after almost 2 years of the first one. In the whole 2 years only reset once. I used this router as a AP,Router,and Repeater. No issues and very easy to set up. I have own Berklin,Linksys,netgear,ZyXel, and Rosewill router's but by far this is the best. The only issue I ever came across with this router is didn't want to connect to my viszo Blu-ray though wifi, but good new it was the player not the router.

Cons: Viszo does not find the wifi for this ASUS router. Couldn't nock down a gold ball for that one Blu-ray players fault.

4 out of 5 eggsUpdate your Firmware to v2. people! And do two tweaks to make this router work properly.

Pros: Cheap. Nice design. Works a heck of a lot better than the junk Tenda W308R I bought that couldn't hold a WiFi signal to save its life.

Cons: The 300Mb rate just won't work for me as it seems to be buggy or something but the default 144Mb rate screams. Yes, I am using a 300Mb USB adapter--a Tenda, unfortunately, but running current drivers (all these USB WiFi adapters use Ralink chips nowadays)---on USB 2.0 but it just keeps dropping the connection or, when I download, the speed just drops from 300Mb to 250, 190, 150, 90, 75, 54, 30, 20, then 10 and after the download completes, it shoots right back up to 300Mb again. Something wonky is going on at 300 megabit speeds. My router is only 10 feet away from my PC.

The B1 revision of this router had the oldest firmware running so, like any good tech, I went out and factory reset it, threw on the latest firmware (, factory reset again, and did my best to get N300 speed working. It just would not work well for me. The reality is, this has four 100 megabit ports. Let me repeat that, 4 *100* megabit ports. You'll never realize 300 megabit speeds on wired ports that are running 100 megabit, especially if you have Internet service that's 100 megabit or greater. You need gigabit ports.

I didn't have Laptops or more computers that could connect at 300Mb to test and see if through WiFi I could achieve 300Mb between PCs but I just chalk it up to a lame Broadcom chipset and buggy firmware. Haven't ventured to DD-WRT. Yet.

There are a couple of tweaks to this device that you really should do to make it usable, at least at 144Mb speed.

1) Update to Firmware
2) Disable WMM
3) Go to Advanced Settings > QoS tab, set Manual Uplink Speed to 102400kbps (that is the maximum speed of a 100 megabit connection in kilobits).

Doing these things has made this Asus router work well for me on my 25Mb Comcast connection. No slowdowns in speed or download speed. YMMV.

If they fix the other bugs, I'll revise my review (if possible).

Other Thoughts: Hey Asus, the newer firmware made things "better" but disable WMM by default in your next firmware update for crying out loud. There are still bugs to be fixed with your router, especially the 300 megabit rate. Get to work.

1 out of 5 eggsProblematic

Pros: Appearance is pleasant. Somewhat easy to set up. Offers 4 different SSID's. Graphic interface of the website is easy with simple to read help files.

Cons: After one day, the router would need to be rebooted for wireless access. The medical billing office needs to have continuous online access, which this router failed to do. Tech support at ASUS recommended upgrading the firmware from their download. After downloading the firmware upgrade files, and extracting them, they would disappear. The router would neither accept the zipped file, nor could it find the extracted file after following the directions on the site. The zipped file did have the firmware upgrade file inside...but it would disappear on every computer I tried to download it to. I ended up having to loan my personal router to the office until the current router could be exchanged or refunded.

Other Thoughts: The ASUS tech said he could not send me the file directly because it was too big. It was actually less than 6 KB. ne. The tech did not even attempt to use a cloud so I could access the file that way.

Manufacturer Response:

Dear Valued Customer,

I am sorry to hear that you had problems with your RT-N12/B1 router. If the file you downloaded was less than 6KB it sounds like you either didn't download the whole file or it wasn't the correct file.
You should get any firmware and/or utility from our ASUS Support page -
The firmware for the RT-N12/B1 is about 5.5MB. If you found a different file please let me know.

If you would like any help, you are welcome to contact me at I am happy to help with any questions, comments, or concerns you may have.

5 out of 5 eggsFAR LESS disappointment in bright white and electric blues...

Pros: Inexpensive & Functions much better AFTER FIRMWARE UPDATE

Cons: None in the past few weeks AFTER FIRMWARE UPDATE

Other Thoughts: I wrote the review a few tiles down entitled "Disappointment in bright white....."

This is to counter my two eggs rating and review after a FIRMWARE UPDATE. There's something you may need to do BEFORE setting this thing up to work; I'll repeat it so there can be no misunderstanding or missed instruction:


Did you get that? I hope you did, else you, too, will be disappointed.

This router is now working well (after 3 weeks with the FIRMWARE UPDATE). ...and appreciation to the Asus tech that answered and directed me to perform a FIRMWARE UPDATE.

5 out of 5 eggsAnother Good Asus Router

Pros: - Good speeds
- Barely ever drops signals
- Good site support/options/settings
- Decent range (will cover a 3 floor distance with a good signal)

Cons: It be nice if Asus had a shell around there routers, they are so "plastic-y", and will crack at a drop (well some, not all).

Other Thoughts: Asus has been making some pretty good routers recently. I have stuck with them for the last 5 years and I don't regret any of it. Def. marches over linksys and netgear in my point of view, because those routers always come up with issues.

1 out of 5 eggsNot for wireless networks.

Pros: Ethernet works and maybe the price.

Cons: Bought one just recently and found that the wireless connection is inconsistent and very picky. It would either connect to my desktop or laptop but not both and only give me some of the internet service if it did work.

2 out of 5 eggsDisappointment in bright white and electric blues...

Pros: Inexpensive & Functions

Cons: Spotty LAN and WAN connectivity

Other Thoughts: Man....

I've had a Linksys WRT54G in the closet for years, all the while running DD-WRT's excellent software. Then heat and years finally fatigue the pup and it begins sputtering. I head to Newegg looking for a replacement, and fall for this thing. Sigh...

The Asus turns on and blinks its pretty blue lights. Sometimes it assigns DHCP for everyone, sometimes only for some machines. Sometimes it connects to my cable modem and serves the 'net, sometimes not so much.

I've had to power-cycle this thing more time in the past month than Moe's gouged Larry's and Curly's eyes. I miss my Linksys 54G, I really do.....

Manufacturer Response:

Dear Valued Customer,

I am sorry you have had problems with your RT-N12 router. Please try doing a Firmware Restore to reset the software on the router. You can follow this guide to perform the procedure -
*It shows the RT-N56u, but the steps are the same on the RT-N12.

Download a new copy of firmware and the utility here -

If you continue to have trouble with your router please contact me at so that I may do what I can to help.

4 out of 5 eggsWorks great with a few tweaks

Pros: Excellent range, very easy initial setup, 3 modes to choose from.

Cons: wifi speeds are unusually slow, needs two extra steps to get good performance.

Other Thoughts: Had this badboy for about two months and speeds have been reliably slow. Couldn't figure it out until I looked at the reviews here and did these two things:

1. Update the firmware to version
2. Turn off "Wireless Multimedia Support Settings" (WMM) in the advanced "professional" settings of web interface.

That did it for me.
