Unable to configure N66U

[TrueTenacity]

Hi,

I bought an N66U yesterday and am having great difficulty in setting it up...

1. I don't have an internet connection at the moment.

2. Every time I change the lan ip or add a dhcp reservation, the router stops responding and I have to reset it to defaults to get it back.

I have updated it to the latest firmware.

have you tried this?

telnet 192.168.1.1
"admin"/password

mtd -r erase nvram
reboot

the "mtd -r erase nvram" was what I originally saw on the internet from someone else for a different router, and I assumed that the Linux commands on that other router would be the same on the RT-N66U. That was a long time ago *smile*.

What actually works with to clear the nvram on the RT-N66U is:

mtd-erase -d nvram

Sorry.

I have updated it to the latest firmware.

1. The router doesn't have an internet connection? Or your computer doesn't have an internet connection?

2. If you're changing the router from 192.168.1.1 to something like 192.168.2.1, your computer will disconnect. That's normal. Most computers will reconnect automatically. I have one that doesn't for whatever reason (it's old). All of the rest of them have no problem reconnecting automatically when changing certain settings on the router...e.g., router local IP address, DHCP reservations, DHCP pool. You might have to re-connect manually or reboot your computer. Or maybe even flush your arp/dns cache.

You can also try removing all of your wireless profiles and then reconnect. I actually create a completely new (never used before) SSID so I don't have to worry about it when changing firmware.

You can also try a different computer or try using a wired connection. It's most likely the computer that is having problems....not the router (at least that's been the case from my similar experience).

Edit: It might be simpler if you just powercycle the router instead of repeatedly clearing nvram over and over.

1. There is no internet connection to the router, still waiting for the phone company to find the house (no I'm not kidding)

2. I tried the latest firmware, I'm now running the Merlin firmware.

I managed to setup the router via my laptop, but now, the router is working like a dream, but nothing can get to the web ui... (2x android phones, iPad, 2x laptops and a PC...)

Am I going to have to wipe the router and setup from scratch every time I want to change something?

Unless the router has a defect, it maybe that you configure some things in such a combination that you run into some hidden bug.
Try the following:

1. Revert to factory defaults (or erase RAM as instructed).
2. Now ONLY configure the bare minimum as guided by the setup wizzard, which is:
3. WAN Connection Type (should be found automatically).
4. Router Admin password.
5. Wireless SSIDs (use alphanumeric characters only, Aa to Zz and 0 to 9), different SSIDs for 2.4 GHz and 5 GHz.
6. Authentication Method WPA2-Personal.
7. Set your WPA Pre-Shared Keys (use alphanumeric characters only, Aa to Zz and 0 to 9), these maybe identical for 2.4 GHz and 5 GHz.
8. Leave the rest default!

Does this work stable and for longer time?

If above works stable and for long time, make additional changes, step by step, test each step and DOCUMENT all the configuration changes you make other than default. Making the changes step by step you may find the one that works out bad.

By changing the LAN and DHCP settings, I assume you have basic knowledge about IP addresses, subnetmasks and what will work or not. You can easily lock your self out too.

I cannot complete the setup wizard as I have no internet at the moment... and the router cannot complete the wizard without internet.

I will try the step by step process.

Have had an managed a router or two for nigh on a decade now, think I've got the basics...

First priority is to get the Internet connection fixed.
Without Internet, there is no need for a router anyway.
