Tomato Firmware

500 Internal Server Error

I put shibby 1. So far its been working great. Or do I need to repeat the above procedure? Thanks for the guide. Seeing you got both the latest Asus router can you confirm your thoughts with regards to performance on them minus being able to install tomato firmware on n66u. I have ordered my n66u but been reading elsewhere performance wise mainly wireless N56 is better. First wanted to say thanks! I found this guide because I blogger I follow posted about it: It appears to me that the current location for the firmware has changed again to here:.

Thought you would like to know. Only 5Ghz wireless is working. I had to drop down to XP to make it work — very frustrating, it took a while to figure this out. It would be a nice footnote in the guide to suggest a different machine if you are having trouble with Win7x Just an addendum to your instructions here… I had some trouble flashing TomatoUSB onto a brand new router out of the box and had to do a little poking to figure out why.

There are four steps that you need to accomplish to get the flash to work. Fancy timing is not required, as you implied, it just has to be done in the proper order…. Plug into the router with a cable and set your PC to have an IP address in the So anything from Press and hold on to the reset button with the power cable disconnected.

Plug in the power cable and turn on the power button so that the RT-N66U turns on. Keep the reset button pressed until the power led begins blink slowly. The router is now in Rescue Mode. Start the firmware restore utility, browse to the downloaded firmware file, and start the upload.

When you are warned that this is not official firmware, click OK. The firmware will upload and the router should restart automatically. Hope this helps someone. Got THE router today. What a nice black beast!!! Flashed it with the tomato, but after some vlantweaking i lost my wireless.

Had to reset it and flash it again. Followed your steps today and they worked liked a charm! I noticed though that the link for the firmware download no longer works. Any solution for this? Would be nice if that is fixed in near future.

I am using Tomato Firmware 1. Personally I have yet to try this out but on my other devices that support USB devices, attaching a hub does not break the functionality. You can try it out. Thanks everyone for the great information. I have a very basic setup, with 5 to 6 connected devices. However, I would like to add a robust QoS setup for an Ooma, insure proper security, etc. I plan on getting u-verse service soon.

It took a while before it finally uploaded the firmware successfully. Once it did, everything seemed to work. But for some reason the 5ghz channel only appears on my Samsung galaxy s2, and not on my Asus N53 dual band adapter. Nevermind I fixed it. Under advanced wireless settings I changed my country region to my country and set the Thanks for the instructions.

I am assuming you are from Singapore. Your router must be set to DHCP mode and both the cable modem and router need to be rebooted. Else the cable modem will remember the last MAC address of the connected equipment and refuse to issue an IP to your newly connected equipment.

I am about to order the N66U and already bookmarked this awesome guide! Thanks shadowandy for sharing this info with us. Is it possible to save the original firmware to disk before flashing the new one?

Press and hold the WPS button on the back while plugging in the power cable. Hold for 30 seconds and release the WPS button, the router will now boot. Thanks for sharing your experience.

I am sure one will panic if the web admin cannot be accessed. Nice guide used it on my new RT-N66U as the pppoe would not work this firmware solved the problem. To upload the firmware you need to hold down the reset button push the power switch on while holding down the reset switch down untill the power light starts flashing on and off.

To access the web interface after installing the firmware the Nvram must be cleared first. You do this by Pressing and hold the WPS button on the back while plugging in the power cable. Hold for 30 seconds and release the WPS button.

It will now reboot. I cannot put the router into the restoration mode. I followed the instruction in the article and in the message from Glenn Sullivan. None of them works. Here is what happens: Is this the signal for the restoration mode, the so called slow blinking? This is all I get, anyway. Then I try a variety of possibilities: I tried releasing the reset button both before starting the flashing process and after that but, no luck. It scans for the router for about 30 secs and then gives the message that the router in not in restoration mode.

Is there another way to flash the Tomato firmware? I have a Mac too and I have access to a terminal. I finally got this thing working. I brought it in to work so that I could work on it in my down time. I think this is the only tutorial that I read that actually made it clear that to clear this out you need to hold down the WPS button for 30 seconds and NOT the reset button.

Thanks for the great advice. I would have hated to spend so much money with the promise of a custom firmware only to have to use the stock firmware. I just installed the tomato-K26USB It seem faster now with the Tomato one and easier to configure. I wander wy Asus dont come first with a firmware as good! I finally managed to flash to Tomato. I was using a third party modified version of Asus firmware and apparently, it was allowing me to go to restore mode.

I first switched back to an original Asus firmware and from there I was able to follow the instruction on this site. If you can make this opiton possible I would be very happe. Can anyone confirm whether Parental Controls work on Tomato?

Kids can still access the internet after hours. Did a quick test and it appears to work. Well, unless your kids are tech enough change MAC addresses on their devices. Worked on the first try without having to do anything beyond the instructions you wrote no setting ip address, performing ceremonial dances to appease the gods, etc….

Just in case anyone else has this questions: Just did the flash on the RT-N66R model, works great. I am having trouble logging back into user interface of the router. When the flashing is completed, i waited for 10 mins. The router seems not willing to reboot itself. And the power led stays ON. My connection icon on my computer shows no connect to the router. Can anybody let us know about 5Gz wireless option on rt n66u at tomato fw? On stock and Merlin Fw there are only 4 channels there to choose.

I do wonder what configuration options now you have? It is visible just on few devices as samsung galaxy s2 and dell xps studio lapt, but nobody else. And I see last messages from ddwrt forum — they do have problems with 5gz either. What is the experience with 5Gz at you guys. Connecting only 1 Ethernet cable to my computer, I get the error: Couple of questions for clarification: Is there a link to describe what the different build types are?

The difference in the nonk and 64k is the amount of nvram set aside for saving the router settings. For feature rich firmwares like TomatoUSB, people found that they ran out of storage space when they enable more features. So it is better to install the 64k builds to avoid migration in the future.

I had to reconfigure from scratch when I changed over to 64k builds. For the features, he used to have a English site. Now is just Polish http: For me, I simply chose the AIO build. Your explanation of the 64k variant was helpful. Does anyone know if this firmware supports running OpenVPN on a separate guest network? As wyred detailed, I had an Invalid IP message when attempting to upload the firmware. The methods mentioned on timing recovery mode did not work for me.

What finally worked was to 1 put the router in recovery mode as mentioned above 2 reboot Windows 7. Did anybody tried to flash RT-n66u directly from Asus original firmware 3. Restart the restore utility. Mine appeared to still be trying to use a now disabled adapter. I managed to flash it in another way, via tftp from my Linux laptop.

Still, I need to be very fast. Since laptop connect to router with cable, while router is in maintenance mode, there is a very short time window when firmware can be uploaded. With Shibby fw is not a problem, as it is small for the moment, but Merlin is bigger, so I had couple of retries.

And, just to share a little bit of my experience: Hi, I am new to Tomato Shibby, but not to 3rd party firmware. I have used dd-wrt in the past. I had been running several stock firmware iterations in the past, all the way up to the latest 3. I rarely had any glitches with wireless connectivity. Since upgrading to tomato-K26USB I bumped up the transmission power from 42 to 80mW but still same. The stock Asus firwmare was set to 80mW and again, wireless network connectivity was reliable.

Nothing else has changed, just the firmware. Did I do something wrong? Any help is appreciated. After installing Tomato, Parental Controls work the way they are supposed to.

Everything is disconnected mid-stream. Same thing with ddwrt, as I have used that in the past on an older router. If you are using a Merlin build, please test it and if it works, I will gladly consider switching. The result was that the parental control works, meaning that the banned computer cannot access internet anymore. I wonder if you tried exactly the same on stock firmware, as it supposed to work too… So, even the parental control is not very granular configurable, it seems to work fine.

Try streaming both before the cut-off time, then see if they continue past the cut-off time. If they both stop, then Parental Controls are working. I wanted to try Tomato-Shibby for this very reason, which seems to have fixed the Parental Controls issue now as both streams stop at the cut-off time, but the wireless connectivity is occasionally intermittent on Tomato I am not sure if it is the TomatoUSB firmware issue but have you tried to baseline your wireless noise floor and choose a wireless channel that is less congested?

Hi shadowandy, no, I have not tried that but perhaps I should. Can you direct me on how to do that please? By the way, thanks for the awesome flashing instructions. To baseline or calibrate your wireless, we will need to measure the existing noise floor for the affected range — 2. To measure the noise floor, 1.

Login to your TomatoUSB web admin using a wired computer 2. To choose a wireless channel that is less congested, 1. Click on the Refresh button 3. If you are unable to locate an unused channel, choose a channel whereby most of the RSSI is in the range of to dBm. The more negative is that number, the weaker is the signal of others e.

Thank you for these instructions but I am not sure what the objective is. Is the goal to change to a specific channel on my router? Right now Tomato24 is on 6 and Tomato50 is on Auto. I got the floor as you suggested dBm. Not sure where to go from here.

Also, someone on the Tomato Shibby General forum stated that the build that I chose might be unstable and suggested flashing an older build. Is there any truth to that? If so, how would I go about flashing to an older build, and which build should I choose? Would I use the same process I used to flash from the Asus stock firmware to the build I have now? The objective is to measure the wireless interference in your area and hopefully get the software to work better by taking account of the surrounding noise.

Thank you very much for your help. As with dd-wrt, the process works smoothly when performed from an XP OS. That was before I installed the firmware. The firmware version on my router is Tomato Firmware 1.

So Yes or No? And if yes, then how? The simple guest account requires only the virtual wl0. For my guest wireless, I had created: My wireless clients could connect, get a DHCP address in the vlan on the separate subnet but there was no internet access.

I assumed that to be a routing or gateway configuration problem but I was not able to resolve the issue. You have a interesting set up. IP address of actual gateway Subnet mask: This routing rule is suppose to route all traffic on the new interface to the next hop your actual gateway. Try if it works. If it have internet access, I suspect your guest wireless might be able to reach out to your non-guest segment via your actual gateway. It might be a security concern. I ask because the factory firmware has a tendency to randomly disconnect hard drives I verified many people were having this issue via Google search.

It does hold an IP belonging to the same subnet as the gateway right? Just trying to figure out how it is routing. My intent is to make it a router for your guest lan while still remaining as an AP for your regular non-guest wireless.

Not pretty sure if it is achievable. For the harddisk, the disconnection could be due to some firmware spinning down the disk when there are no activities.

I vaguely remember that TomatoUSB has got this feature. Do experiment with this feature to see if it solves your issue. Cannot really help on this issue as I am not using this feature. I have direct access as usual. Keep the reset button pressed until the power led begins blink slowly. The router is now in Rescue Mode. Start the firmware restore utility, browse to the downloaded firmware file, and start the upload. When you are warned that this is not official firmware, click OK. The firmware will upload and the router should restart automatically.

I couldn't use the web ui to do the install, as it rejected the firmware as being wrong not signed presumably. Using the firmware restoration inside a Virtual Box VM worked fine. Play air… Hopefully this works! I've spent the last days kinda reading what I can about it but doesn't seem to be a lot of clear information out there.

For now, I just have 2 questions…. I have his trx file but of course when I try to flash the basic firmware that comes with the router with the trx file the router complains that it is a incorrect image!

Check if it's a 4MB or 8MB flash version. No matter what you do, you won't be able to flash tomato without using the method listed above. You use the method above, and use the trx file provided above…. It worked for me. TomatoUSB Unleash your router. Wiki Forum Help us! Admin Recent changes List all pages Site Manager for admins.
