Netgear Router Firmware Upgrade Invalid File Name

Fortunately, the steps to switch from Tomato to DD-WRT on your NETGEAR router are virtually the same as above, only you have to rename the DD-WRT firmware file to have a.TRX extension. Once you've renamed the file, head to the Administration tab, select the file you renamed, upgrade, perform the 30-30-30 reset, and you should be ready to go. Updating your router's firmware (its operating system) on a regular basis is important for: better connections; reliable security; fixing bugs. That's why we push updates directly to your router. We test and verify any manufacturer updates before sending them to your router. Because Frontier updates your firmware automatically.

WARNING - PLEASE READ BEFOREUPGRADE:

Upgrading firmware (in most cases) will reset all settings backto defaults. This includes the login passwords, the IP address andInternet connection settings provided by your ISP. Please ensureyou have backed this information up before proceeding.

We recommend performing a reset to factory defaults after anyfirmware upgrade to avoid conflicts with prior configurations.

How To Update Netgear Router

Do NOT upgrade firmware from a computerconnected wirelessly. Use a computer that connects to the routerusing an Ethernet cable. Join xbox party on mac. You may cause the router to becomeinoperable due to the wireless connection dropping while theupgrade is in process.

To upgrade the firmware of your router, you will first need todownload the required files from the D-Link Support page for thisrouter. After saving it to a local storage device (e.g. harddrive),you will have to unzip the file.

Once this is done, log in to the web configuration interface, goto the TOOLS or MAINTENANCE tab and click on the UPDATE FIRMWARE button on theleft-hand side. Click on Browse, browse to andselect the file that you saved before, then click on Update Firmware or Firmware.

The router will then copy the new firmware into its memory andperform the update, after which it will reboot. This will takeapproximately three minutes.

I have almost 300 Mb without Shortcut Forwarding Engine and 650 Mb/s throughput LAN <> WAN with SFE turned on, on my R6400v2 with the latest Kong build
Try 'erase nvram' from Command Line Interface / Putty and put settings in manually

You inspired me to change firmware to dd.
Before I started I cheked the connection speed on stock firmware on wifi 5GHz and 2.4
5 GHz was 150 Mb and 2.4 was 80-90 Mb.
5 minutes later I had DD with clean memory. I set only wlan and lan and I repeated connection speed (same servers). Results was withering. 5Ghz has 7Mb, 2.4 has 3 Mb.
Tell my why there are such differences with speeds. I have two other devices (TP-Link) and there are no such problems. Both working on DD.
Now I come back to stock.

We can’t do that. It’s out of our control.

I did a quick search through the pages of this thread, but saw no mention about the R6700v2. What's the status on this? Can I use any of the firmware versions with it? Thanks!

I trust you used these builds.
Report your findings in the respective build threads so that it is noted by the devs

Tried both. PPP-based protocols didn't work on WAN port.

That's a MediaTek chipset, not Broadcom. The only two devices with the same hardware AFAIK are the DIR-878 and DIR-882. The R6700v2 is not directly supported to my knowledge, but you might check through the proper forum (Ralink, I think?) to see if anyone has a workaround.

Read the second post of this thread.
Many of us have had our routers not working. Though we call it bricked - it is truly bricked only when you are unable to ping the router. If you can ping the router, it is easy-peasy to recover. I have done this a dozen times already.
You are able to telnet to the router. Definitely not bricked. NMRPFLASH should get it up and running easily. Read the instructions carefully, though. Needs patience.

Ive tried most everything suggest (most as in I may have missed something in the tons of posts). I am still unable to flash anything it seems. I keep on getting the error 'This firmware is incorrect! Please get the firmware file again and please make sure it is the correct firmware for this product'.
I tried flashing kong to Netgear firmware months ago (cant find the package anymore) and it brought me to the netgear r6400 firmware version 1.0.0.26_1.0.14. I have tried everything I can think of - I cant even tftp new files to it BUT I can login / ping which means its not bricked.

From DDWRT? Or Netgear?

I downloaded all I could find. I did v2 from beginning to current for ALL firmware from netgear, not a single one was successful.
