Anyone had any success? Have a Netgear R7000 AC1900 and want to flash it to a DR Regional location.

It's from the US. DDWRT?

Thanks.

Gringo- it means nothing.

Im guessing if I unlock North America region there will be no compatible region for the DR. Maybe South America. I am fairly sure there is no Carribean Region or otherwise.

I am trying to optimize the thing as it is not operating at 100%...dropping wifi- lagging- dropping out.

Your router is ddwrt compatible so nothing ventured, nothing gained. dropped internet can be related to new firmware upgrades or just the fact that you have been running the same settings for so long they have become corrupted in the router's ROM.

Before deciding to flash a different fw, I would do a hard reset of what you have. Reconfigure everything and see if that helps.

If no success, I'd go back to the last fw version and see if that is any better and if not then reinstall from scratch the current factory fw version.

The current ddwrt fw version is not always the best. You'll need to read the forum for your router to see what most people have decided is working well for them.

Before flashing ddwrt, make sure you know exactly how to do that and revert back to factory fw if need be. Some routers even have a means of reviving a bricking that does not entail throwing the router at the wall. Make sure you have all the files and software you need to install ddwrt, revert to factory and unbrick (if necessary) on your HD before you begin.

Learn what a 30-30-30 reset is if you don't already know. Resetting your current fw should be enough fix the problem unless the radios are dying due to age and operating at high temps for a long time. Then a new router is the way to go.

The difference in regional fw is primarily regulation compliance due to signal strengths and radio interference considerations. The core fw functions are usually the same regardless of region.

Good luck. If you are successful with ddwrt, you'll really like the extra config control you have. Don't be tempted to set your wifi strength to max, you could hasten the burnout of your radios.

Cdn-Gringo. All correct.

I have flashed a number of routers and still did a wrong version once and bricked one with firmware was just one -dash number off from the correct firmware. No recourse for that one to revive it without a JTAG interface as far as I can tell. Coincidentally the job that allowed me to retire to the DR was selling JTAG interfaces and firmware development software tools to companies like CISCO and Netgear.

If you were going to replace the router anyway, then DD-WRT might make a difference.

Router hard reset fixes most problems, but you have to reconfigure it. Sometimes having too many WiFi connection on the same router will cause conflicts that drop a connection. Usually unplugging the router power cable, waiting 10 seconds and replugging will mean everything gets back on. And if you are in an area of lots of WiFi signals try setting the channel to 1 or 6 or 11 These are non-overlapping 2.4 Ghz channels but there may be interference on one channel. For 5 Ghz use non-overlapping channels also between 48 and 149.
If fact it is good to have 5 Ghz capable devices on 5 Ghz connections if they are close to the router. And always plug your TV direct to the router if possible - You'll get a better flicker free experience

Also if you have updated you computer WiFi software that can lead to problems. Roll back the WiFi drivers on your computer, or update them to see if that fixes anything - It did on my laptop

I just bought the router. New out of the box. I will save my factory FW then maybe flash it with ddwrt and see my options.

If you use claro they wont help you because you didnt buy the router to them, their router when you flash it has factory configuration with the parameters for Claro Dominican Republic, and also out of that They dont have fu.....g idea about what you are talking about. What I did was asked a friend to take screen captures of one router working with Clara and based on that info I sucessfully configured it the one I was working.

I am assuming you want DD-WRT on your router to set it up with router-based VPN or Dynamic DNS... ! Make sure your router can cope with that even after DD-WRT upgrade, aka someone has tested it, some routers just can't do it.

I put the Netgear Nighthawk app on all devices as it contains a "Smart Switch" feature and it seems to be doing the trick. It auto adjusts the device to best bandwidth of the router.

There is also a button to click that enables all devices to respond as quickly as possible so they are not lagged by slower devices on the network.

The routerlogin interface has many options on it.

Im going to ride with this before I do any new Fw installs.

Thanks for all the tips.

Yes this. I wanted to put my VPN into the router so any device is covered instead of having the VPN on all devices. The R7000 is an open VPN from the factory so cannot input a private VPN.
