I came home one night to find that my internet wasn't working. So, I go check the cable modem and notice it looks fine, then look at the router, a WZR-HP-G300NH to see a solid green power light and a solid red diag light. After about 45 seconds, all the lights would come on, then shut off and repeat the process, rebooting itself every 45 seconds or so.
Wzr-hp-g450、wzr-hp-g450h、wzr-hp-g450ha 親機の電源が入っていることを確認します。 親機の 底面 にある、[RESET]スイッチを約3秒間(DIAGランプが点灯するまで)押し続けます。.
Searching around trying to find the 'right' information on debricking a Buffalo WZR-HP-G300NH router, sent me to countless forums and all sorts of 'try-this-try-that' scenarios. I am not a fan of forums because everyone has the same problem, but no one ever has a solid fix. Well, after pulling my hair out, I finally figured out how to re-flash my endless reboot router back to a good ol' DD-WRT firmware, using Pumpkin TFTP.
I realize someone else has probably already blogged on this, but I didn't find their page that was specific to the solid diag & endless reboot, so I'm trying to get some SEO going for that specific problem. First off, if you try to ping the router in this state, you WILL NOT see it. I have a feeling ICMP is turned off because I couldn't even get a reply after setting a different timeout period on ping. Ping 192.168.11.1 -t -w 2 Notice the 192.168.11.1 This is the IP of the router when it's in the endless reboot cycle (or) the double blinking diag.
Secondly, I did all of this in Windows 7. Most of the forums and guides, show how to use Linux. For those of us who don't use Linux on a regular basis, I can tell you this DOES work on windows. (Dunno about XP?) For the most part, I'm going to use what other's have pieced together already, with a few of my own tid-bits to help bring things along. Keep in mind, I blog stuff so I can go back and have a solid guide on how to fix something. Take this info 'AS-IS'.
I recommend that you take a look at the instructions all the way through, before proceeding with things. Go out to: and take a look on how you need to setup your computer to transfer the file. The only part you really need to know, is getting the ARP setup so 192.168.11.1 points to the MAC address of your router. Once you have this part, move to step 2 For whatever reason (Windows is stupid) you can't just add it through the arp command.
Long story short you have to do a: route print Find the 'Number' associated with your ethernet interface, then type: netsh interface ipv4 add neighbors?? 192.168.11.1 xx-xx-xx-xx-xx-xx Where?? Is your interface number and xx-xx.
Is the routers mac address. Note About The MAC: Most routers have a sticker on it that says mac: xx-xx-xx-xx-xx-xx. On the WZR-HP-G300NH, the MAC address is the same thing as what the 'SSID' is. Weird and nonconformant, but whatever. Look to the SSID for the mac address. Next, we are going to download the firmware that will allow you to get things going.
This is the stock firmware, provided by Buffalo and there are two version to note: 1) the proprietary Buffalo version - Official 2) the Buffalo DD-WRT version In order to unbrick it, you will need the Official version. I am yet to get the DD-WRT Buffalo version to work. If you do want to move over to DD-WRT after it's unlocked, I recommend getting both the Official and DD-WRT versions. Just make sure you flash the 'Official' version first. Then you can upgrade to DD-WRT using the web interface and finally update to a non-buffalo DD-WRT firmware. To get the downloads, go to the official Buffalo Support site: Select the router from the drop down and you will find the two firmware versions listed. As of this writing, (2011/01/02) the two versions available are: 1.76 - Official V24-SP2 build 14998 - DD-WRT Professional.
Now that you have the IP set on your computer to something like 192.168.11.2, the ARP setup for the router MAC and the necessary files downloaded, go out and download the tftp program I recommend which is and can be. Some other folks have mentioned that they couldn't get the Linksys tFTP program to work.
Pumpkin tFTP has yet to let me down. Launch Pumpkin TFTP program, point to the firmware you wish to push, whether it's the official or DD-WRT Professional and begin the transfer. At this point, it's assumed that your router is unplugged. Plug-in your router and the transfer should begin around 15 seconds of it being turned on. Watch for the 'send' process and once it's completed, the router diag light will begin to blink for a couple of minutes.
DO NOT turn it off during this process. If it takes longer than say. 15 min, you might unplug it and try it again. Some have reported that it takes every bit of 15 minutes before it reboots.
I think it only look mine around 10 though. If you want to be safe, then wait 20:) If for some reason you get a double blinking diag light at any point, unplug the router and try to re-send the firmware through tFTP. The diag light should stay solid for about 20 seconds before it goes to the double diag blink. If the router doesn't reboot on it's own after the flash is complete, (Wireless light blinking) and it's back to a solid diag light, go ahead and un-plug it and plug it back in. If it works successfully, you should now be able to access the web interface at 192.168.11.1 If you decided to put the Buffalo DD-WRT professional version on so you can upgrade to the latest DD-WRT version, simply download the webupgrade version of DD-WRT for the router and flash it through the web interface. Notes.
If you successfully flash the firmware and you can't access the web interface or ping the router ip (192.168.11.1), chances are there's something screwy with the arp table. Try issuing the arp -d command to clear your arp cache, then re-add the router mac using the netsh command listed above. If I forgot something, or you want me to add / change something, feel free to let me know and if this works for you, let others know in the comments! This worked for me - after many gyrations around and around. Situation: Bad flash left me with a solid power light and DIAG light. No response to Ping, or any other probes of the device. Solution: Using Windows XP Pro, and a direct wired connected between the laptop and the Buffalo.
Used LAN port 1 (furthest from the WAN port) - so I don't know if it matters which port is used, Changed the network card to 100Mbps and half-duplex (not sure if the HD was required), 192.168.11.2, 255.255.255.0, Downloaded a.enc file from the Buffalo website, Created the.bat file shown above. Using the 02-AA-BB-CC-DD-1A MAC address was required (not the true MAC address of the device), Get everything ready on the laptop.
Power on the Buffalo. Wait 12 seconds (until the laptop says the ethernet card is connected), then start the bat file, Smile - as the DIAG light starts to flash and otherwise show life. Be patient, and wait for the router to load the new firmware, and start up. The MAC address is usually either on the side of the case, or on the bottom. It will be a random string of letters and numbers with dashes or a colon between them. There are 12 total characters and the letters will never go past the letter F.
(A-F and 0-9) For example, you're looking for something with a pattern of: xx-xx-xx-xx-xx-xx or xx:xx:xx:xx:xx:xx A Real World example will look like: 9E-54-95-2D-50-62 or 91:BF:7A:16:CA:17 In some rare cases, vendors will print the MAC address without any separator like so: 0F 35 95 E9 B5 DA Hope that helps! This seemed to work for me, no more rebooting after red diag light. Now I have wifi symbol going on and off intermittently, which is apparently normal. Unfortunately I uploaded the 'V24-SP2 build 14998 - DD-WRT Professional' image as suggested above, and now I cant find the IP address of the router. 192.168.1.1 and 192.168.11.1 don't seem to work, so I haven't been able to connect to it. The wifi seems to be working - it gives me an SSID to connect to that is very similar to the SSID printed on the back of the router, but I don't know what password to use.
Any ideas appreciated!:-). Glad you got it going:-) The site's pretty old (been around since 2007) but it still gets some tender love from time-to-time. This page is pretty old though and while I still have my Buffalo routers, I've moved on to hardware firewalls and Google Wifi for my setup which is a breath of fresh from the days of trying to manage DD-WRT. I'm not a big fan of my hardware firewall, but I absolutely love the Google Wifi.
It just works. All the time. Good luck to ya and hope you get some great service out of those routers!
The 30-30-30 reset There are no specific instructions for this model yet, but you can always do the 30-30-30 reset as follows:. When router is powered on, press the reset button and hold for 30 seconds. (Use a paper clip or something sharp). While holding the reset button pressed, unplug the power of the router and hold the reset button for 30 seconds. While still holding the reset button down, turn on the power to the unit again and hold for another 30 seconds.
This process usually works for resetting any router to it's factory setting. Note: It is worth reading more about and what the risks and considerations are when resetting your router this way, instead of just rebooting it.
How to login to the WZR-HP-G302H To login to the WZR-HP-G302H router and change the settings, you can follow these steps:. Make sure you are connected to the router's network, either by Wi-Fi or ethernet cable. Open your browser and visit.
You should be prompted with a login dialogue. Enter the username: root and if it requires a password, leave it empty or try with admin/ password Note: If you have already changed the password use that instead. You will now be logged in.
If you haven't yet changed the defaul password, we recommend that you change it first thing you do after logging in. If these instructions don't work for your router, you can always try a factory reset to get the default, or try some other common, as they can usually be shared across models/variants. WZR-HP-G302H Firmwares Staying up to date with the latest firmware is a good idea to keep your router even more secure from various security flaws. If you want to squeeze a little bit of extra functionality out of your router, consider flashing an open-source firmware like dd-wrt, openWRT or LEDE.
Flashing a custom ROM can greatly increase the stability and functionality of your old router. Following are the firmwares that we have identified existing for the Buffalo WZR-HP-G302H: Flashing dd-wrt on the Buffalo WZR-HP-G302H We haven't find any specific instructions for flashin dd-wrt onto the Buffalo WZR-HP-G302H, but you can read the over at dd-wrt to get a clue on how to proceed (As this model is listed as supported). Note: Always make sure to read the wiki and howtos of dd-wrt before doing any flashing. Flashing OpenWrt on the Buffalo WZR-HP-G302H The Buffalo WZR-HP-G302H is supported by OpenWrt according to their Table of Hardware. So flashing OpenWrt onto it should be quite straigthforward. We couldn't find any specific instructions for flashin OpenWrt on the Buffalo WZR-HP-G302H, but since it's listed in their Table of Hardware as supported, you can head over to the and read on there.
Note: Flashing custom firmwares is always on you're on own risk. Make sure to read OpenWrt's wikis to understand the risks and how to proceed if something goes wrong.
