43 of 44 people found the following review helpful  Initial shipping batch contained defective firmware - after update, nearly perfect., January 17, 2012 This review is from: ASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router (Personal Computers) Well, as mentioned in another review, the firmware in the initial shipment of these (3.0.0.3.72) is broken. Not buggy, not unstable, but broken. You CANNOT connect to the Internet with the factory firmware, at least in the initial release. I purchased one, returned it in exchange for another one, and the second one had the exact same problem. As discussed on this here: [...] You must manually enter a URL [...] then change to a language other than English, then update the firmware. (The current version from the ASUS website is 3.0.0.3.90 as of 1/13/2012) Of course, that means you need to download the firmware first, since you can't connect to the Internet with the factory firmware. And of course, a router is required for most people to access the Internet, so... well, you can see where I'm going with this. After the firmware update, things were much better. I had the Internet connection set up in a few minutes, and the speed was unbelievable. Certainly the fastest...

Here is an update now that I have owned it a while (5 1/2 weeks): 1. FYI Asus is releasing firmware version 102 on Monday (those who have been able to get a hold of that version in the meantime said it works great and has resolved the few issues that remained, which affected some users, depending on which advanced features they needed). They have been very quick, compared to other networking companies especially, to release new firmware after getting bug reports and working on the fixes ([...]). 2. As an update, my RT-N66U has been up (without a reboot) and running stably since I first configured it 5 1/2 weeks ago. (It does get rebooted to load the new firmware of course, just like a Windows PC needs a reboot after installing updates). 3. No wifi disconnects to date! 4. Smallnetbuilder.com has posted test results and it is, as of now (February 25 2012), their top performing router in terms of wireless (wifi) performance...

25 of 26 people found the following review helpful Solid router, AWESOME range, READ FOR ENGLISH FIRMWARE CONFIG HELP!, January 19, 2012 This review is from: ASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router (Personal Computers) I got my shiny new RT-N66U today from Amazon. I do networking for a living and figured even though I'd seen reports of the shipping factory firmware being broken in English mode, it would be no problem. WHAT A PAIN!!!!!!!!!!! Come on Asus!!!! The short and sweet version of how to get your router up and running with 3.0.0.3.72: *Download 3.0.0.3.90 firmware from [...] *Extract RT-N66U_3.0.0.3_90.trx to somewhere on your computer *Log in to 192.168.1.1 (User:admin Pass:admin) *Complete the initial setup wizard using any info you want. Just GET THROUGH IT. It will display a broken page at the end. *Enter 192.168.1.1 in your web browser *Click on "Administration" on the left *Click on "Firmware Upgrade" on the top tab *Switch the language box in the top-right-hand corner from "English" to something else. I used French. *Upload RT-N66U_3.0.0.3_90.trx ***WAIT FOR IT TO FINISH*** *When it's... Read more Help other customers find the most helpful reviews Was this review helpful to you? |
